On-​​demand automotive fleet electrification can catalyze global transportation decarbonization and smart urban mobility

ABSTRACT: Mobility on-demand vehicle (MODV) services have grown explosively in recent years, threatening targets for local air pollution and global carbon emissions. Despite evidence that on-demand automotive fleets are ripe for electrification, adoption of battery electric vehicles (BEVs) in fleet applications has been hindered by lack of charging infrastructure and long charging times. Recent research on electrification programs in Chinese megacities suggests that top-down policy targets can spur investment in charging infrastructure, while intelligent charging coordination can greatly reduce requirements for battery range and infrastructure, as well as revenue losses due to time spent charging. Such capability may require labor policy reform to allow fleet operators to manage their drivers’ charging behavior, along with collection and integration of several key data sets including (1) vehicle trajectories and energy consumption, (2) charging infrastructure installation costs, and (3) real-time charging station availability. In turn, digitization enabled by fleet electrification holds the potential to enable a host of smart urban mobility strategies, including integration of public transit with innovative transportation systems and emission-based pricing policies.

Exploring the Enabling Environments, Inherent Characteristics and Intrinsic Motivations Fostering Global Electricity Decarbonization

The need for transitioning towards low-carbon energy systems, and the recent boom in available data, allows for a constant re-evaluation of global electricity sector decarbonization progress, and its underlying theoretical assumptions. Arguably, the existing decarbonization literature and institutional support frameworks focus on top-down supply side mechanisms, where policies, goals, access to financing, and technology innovation are suggested as the main drivers. Here, we synthesize eleven global datasets that range from electricity decarbonization progress, to quality of governance, to international fossil fuel subsidies, and environmental policies, among several others, and use methods from data mining to explore the factors that may be fostering or hindering decarbonization progress. This exercise allows us to present numerous hypotheses worth exploring in future research. Some of these hypotheses suggest that policies might be ineffective when misaligned with country specific motivators and inherent characteristics, that even in the absence of policy there are particular inherent characteristics that foster decarbonization progress (e.g., relatively high local energy prices, foreign energy import dependency and the absence of a large extractive resource base), and that the interaction ofcountry-specific enabling environments, inherent characteristics, and motivations is what determines decarbonization progress, rather than stand-alone support mechanisms. We present the hypothesis that existin gsupport mechanisms for decarbonization may be relying too much on blanket strategies (e.g., policies, targets),and that there is a need for support mechanisms that encompass a wider diversity of country-specific underlying conditions.

Power system balancing for deep decarbonization of the electricity sector

We explore the operations, balancing requirements, and costs of the Western Electricity Coordinating Council power system under a stringent greenhouse gas emission reduction target. We include sensitivities for technology costs and availability, fuel prices and emissions, and demand profile. Meeting an emissions target of 85% below 1990 levels is feasible across a range of assumptions, but the cost of achieving the goal and the technology mix are uncertain. Deployment of solar photovoltaics is the main driver of storage deployment: the diurnal periodicity of solar energy availability results in opportunities for daily arbitrage that storage technologies with several hours of duration are well suited to provide. Wind output exhibits seasonal variations and requires storage with a large energy subcomponent to avoid curtailment. The combination of low-cost solar technology and advanced battery technology can provide substantial savings through 2050, greatly mitigating the cost of climate change mitigation. Policy goals for storage deployment should be based on the function storage will play on the grid and therefore incorporate both the power rating and duration of the storage system. These goals should be set as part of overall portfolio development, as system flexibility needs will vary with the grid mix.

Opinion: More big PG&E rate hikes if use of outdated system continues

EAST BAY TIMES: MARCH 4, 2021: For the original, click here. Opinion: Daniel M Kamen If you live in Northern California, your utility bill likely will rise by 8% this month. For Pacific Gas & Electric customers, this will be the seventh year in a row of increases. The company’s rates have doubled since 2005 — and they’re going to get much worse unless PG&E changes its ways. Simply put, utilities are spending too much money on the same outdated, unreliable system. Energy consumers are forced to rely on power plants in far-away places to distribute energy on an expensive maze of poles and wires to power our homes. We’ve already seen how running power lines through remote forests can spark massive, deadly wildfires.image But we have the technology today to reduce the risk of wildfires, lower electricity bills and provide reliable clean energy. The solution is simple: Generate and share more energy where it’s being used. The benefits are tremendous: Higher levels of reliability, flexible and smarter systems, improved environmental quality and huge environmental justice wins for frontline and under-served communities. This is California, the land of innovation and new ideas. Yet utilities in the state are planning to spend $15 billion over the next two years on outdated energy technologies. They need to pivot to invest in decarbonization, efficiency and energy storage. It’s for their own and their customers’ financial well-being.

From this spending binge, the worst is yet to come. California regulators expect rates to go up 20%-40% in just the next three years.  As we rebuild after a pandemic, who will be able to afford this? Gov. Gavin Newsom deserves praise for his commitment to clean electricity. While utilities are poised to spend billions of dollars that will only lead to rate hikes, we have better solutions that reduce rates for everyone. Solar and wind are the least-cost forms of generation, so let us target investments there instead. A study put together by Dr. Christopher Clack, a weather scientist formerly with the National Oceanic and Atmospheric Administration, found that an energy system built around local solar and batteries could save the United States $473 billion by 2050. A model developed in my laboratory comes to the same conclusion. We’re already seeing the benefits of local solar and batteries here in California. In 2018, California’s Independent System Operator canceled $2.6 billion in utility spending thanks to local solar and efficiency improvements. We should be encouraging this because the people who are hurt most by rate hikes are always those who can least afford it. Low-income communities also face the highest pollution exposure levels from generation of carbon-based energy. It is no secret that the current utility business model of “the more you spend, the more you profit” is broken. It’s time to innovate and put communities and people at the center of the solution. Local clean energy will boost the economy, create jobs and make electricity cleaner and more affordable for everyone. Newsom recently called for a “new paradigm” for how we produce and distribute energy. He challenged policymakers to make energy more local and to look at clean energy technology such as rooftop solar and batteries. We can meet that challenge.

The Activists Who Embrace Nuclear Power

For the original in The New Yorker (February 19, 2021), click here. In 2004, Heather Hoff was working at a clothing store and living with her husband in San Luis Obispo, a small, laid-back city in the Central Coast region of California. A few years earlier, she had earned a B.S. in materials engineering from the nearby California Polytechnic State University. But she’d so far found work only in a series of eclectic entry-level positions—shovelling grapes at a winery, assembling rectal thermometers for cows. She was twenty-four years old and eager to start a career. Screen Shot 2021-02-19 at 11.21.04 AM One of the county’s major employers was the Diablo Canyon Power Plant, situated on the coastline outside the city. Jobs there were stable and well-paying. But Diablo Canyon is a nuclear facility—it consists of two reactors, each contained inside a giant concrete dome—and Hoff, like many people, was suspicious of nuclear power. Her mother had been pregnant with her in March, 1979, when the meltdown at a nuclear plant on Three Mile Island, in Pennsylvania, transfixed the nation. Hoff grew up in Arizona, in an unconventional family that lived in a trailer with a composting toilet. She considered herself an environmentalist, and took it for granted that environmentalism and nuclear power were at odds. Nonetheless, Hoff decided to give Diablo Canyon a try. She was hired as a plant operator. The work took her on daily rounds of the facility, checking equipment performance—oil flows, temperatures, vibrations—and hunting for signs of malfunction. Still skeptical, she asked constant questions about the safety of the technology. “When four-thirty on Friday came, my co-workers were, like, ‘Shut up, Heather, we want to go home,’ ” she recalled. “When I finally asked enough questions to understand the details, it wasn’t that scary.” In the course of years, Hoff grew increasingly comfortable at the plant. She switched roles, working in the control room and then as a procedure writer, and got to know the workforce—mostly older, avuncular men. She began to believe that nuclear power was a safe, potent source of clean energy with numerous advantages over other sources. For instance, nuclear reactors generate huge amounts of energy on a small footprint: Diablo Canyon, which accounts for roughly nine per cent of the electricity produced in California, occupies fewer than six hundred acres. It can generate energy at all hours and, unlike solar and wind power, does not depend on particular weather conditions to operate. Hoff was especially struck by the fact that nuclear-power generation does not emit carbon dioxide or the other air pollutants associated with fossil fuels. Eventually, she began to think that fears of nuclear energy were not just misguided but dangerous. Her job no longer seemed to be in tension with her environmentalist views. Instead, it felt like an expression of her deepest values. In late 2015, Hoff and her colleagues began to hear reports that worried them. P.G. & E., the utility that owns Diablo Canyon, was in the process of applying to renew its operating licenses—which expire in the mid-twenty-twenties—with the federal Nuclear Regulatory Commission. Because its cooling system takes in and spits out about 2.5 billion gallons of ocean water each day, the plant also needs a lease from the California State Lands Commission in order to operate, and P.G. & E. was applying to renew that as well. Environmental groups had come to the commission with long-standing concerns about the effects of the cooling system on marine life and about the plant’s proximity to several geologic faults. The commission, chaired by Gavin Newsom, then the lieutenant governor, had agreed to take those issues into account. At a meeting that December, Newsom said, “I just don’t see that this plant is going to survive beyond ’24-2025.” Around this time, Hoff discovered a Web site called Save Diablo Canyon. The site had been launched by a man named Michael Shellenberger, who ran an organization called Environmental Progress, in the Bay Area. Shellenberger was a controversial figure, known for his pugilistic defense of nuclear power and his acerbic criticism of mainstream environmentalists. Hoff had seen “Pandora’s Promise,” a 2013 documentary about nuclear power, in which Shellenberger had been featured. She e-mailed him to ask about getting involved, and he offered to give a talk to plant employees. Hoff publicized the event among her colleagues, and baked about two hundred chocolate-chip cookies for the audience. On the evening of February 16, 2016, a couple hundred people filed into a conference room at a local Courtyard Marriott hotel. Shellenberger told the audience that Diablo Canyon was essential to meeting California’s climate goals, and that it could operate safely for at least another twenty years. He said that it was at risk of being closed for political reasons, and urged the workers to organize to save their plant, for the sake of their jobs and the planet. Kristin Zaitz, one of Hoff’s co-workers, was also in attendance. A California native and civil engineer, she had worked at Diablo Canyon since 2001, first conducting structural analyses—including some meant to fortify the plant against earthquakes—and then managing projects. Zaitz, too, came from a background that predisposed her to distrust nuclear power—in her case, an environmentally minded family and a left-leaning social circle. When she first contemplated working at Diablo Canyon, she imagined the rat-infested Springfield Nuclear Power Plant on “The Simpsons,” where green liquid oozes out of tanks. Eventually, like Hoff, she changed her thinking. “What we were doing actually aligned with my environmental values,” she told me. “That was shocking to me.” Zaitz and Hoff sometimes bumped into each other at state parks, where both volunteered on weekends with their children. After Shellenberger’s talk, they lingered, folding up chairs and talking. Before long, they decided to team up. Using the name of Shellenberger's site Save Diablo Canyon, they organized a series of meetings at a local pipe-fitters’ union hall. They served pizza for dozens of employees and their family members, who wrote letters to the State Lands Commission and other California officials. Other nuclear plants across the country were also at risk of closing, and soon they decided that their mission was bigger than rescuing their own plant. They wanted to correct what they saw as false impressions about nuclear power—impressions that they had once had themselves—and to try to shift public opinion. They would show that “it’s O.K. to be in favor of nuclear,” Zaitz said—that, in fact, if you’re an environmentalist, “you should be out there rooting for it.” Hoff and Zaitz formed a nonprofit. Like the leaders of many other movements led by women—protests against war, drunk driving, and, of course, nuclear power—they sought to capitalize on their status as mothers. They toyed with a few generic names—Mothers for Climate, Mothers for Sustainability—because they worried that the word “nuclear” would scare some people off. But they ultimately discarded those more innocuous options. “We wanted to be really clear that we think nuclear needs to be part of the solution,” Zaitz said. They now run a small activist organization, Mothers for Nuclear, which argues that nuclear power is an indispensable tool in the quest for a decarbonized society. On December 8, 1953, President Dwight Eisenhower delivered his “Atoms for Peace” speech at the United Nations General Assembly. He described the dangers of atomic weapons, but also declared that “this greatest of destructive forces can be developed into a great boon, for the benefit of all mankind.” Eisenhower proposed that governments make contributions from their stockpiles of uranium and fissionable materials to an international atomic-energy agency. One purpose of such an agency, he suggested, would be “to provide abundant electrical energy in the power-starved areas of the world.” The first commercial nuclear power plant in the United States opened four years later, in Beaver County, Pennsylvania. In the following decades, dozens more were constructed. There are currently fifty-six nuclear power plants operating in the U.S. They provide the country with roughly twenty per cent of its electricity supply— more than half of its low-carbon electricity. The plants were not always presumed to be environmentally unfriendly. At the dawn of the nuclear age, some conservationists, including David Brower, the longtime leader of the Sierra Club, supported nuclear power because it seemed preferable to hydroelectric dams, the construction of which destroyed scenery and wildlife by flooding valleys and other ecosystems. But Brower changed his mind in the late nineteen-sixties and, after a bitter split within the Sierra Club over whether to support the construction of Diablo Canyon, left to found Friends of the Earth, which was vehemently anti-nuclear. As John Wills explains in his 2006 book, “Conservation Fallout,” these disputes coincided with broader philosophical shifts. Conservationism—with its focus on the preservation of charismatic scenery for outdoor adventures—was giving way to the modern environmentalist movement, sparked in part by Rachel Carson’s 1962 book, “Silent Spring.” Carson’s book, which investigated the dangers posed by pesticides, articulated an ecological vision of nature in which everything was connected in a delicate web of life. Nuclear power was associated with radiation, which, like pesticides, could threaten that web. By 1979, the U.S. had seventy-two commercial reactors. That year proved pivotal in the shaping of public opinion toward nuclear power in America. On March 16th, “The China Syndrome,” starring Jane Fonda, Jack Lemmon, and Michael Douglas, was released; the film portrayed corruption and a meltdown at a fictional nuclear plant. Twelve days later, one of the two reactors at the Three Mile Island Nuclear Generating Station in southeastern Pennsylvania partially melted down. Most epidemiological studies would eventually determine that the accident had no detectable health consequences. But at the time there was no way the public could know this, and the incident added momentum to the anti-nuclear movement. By the time of the Chernobyl catastrophe, in Soviet Ukraine, in 1986—widely considered to be the worst nuclear disaster in history—opposition to nuclear power was widespread. Between 1979 and 1988, sixty-seven planned nuclear-power projects were cancelled. In the mid-eighties, the Department of Energy began research into the “integral fast reactor”—an innovative system designed to be safer and more advanced. In 1994, the Clinton Administration shut the project down. Today, the looming disruptions of climate change have altered the risk calculus around nuclear energy. James Hansen, the nasascientist credited with first bringing global warming to public attention, in 1988, has long advocated a vast expansion of nuclear power to replace fossil fuels. Even some environmental groups that have reservations about nuclear energy, such as the Natural Resources Defense Council and the Environmental Defense Fund, have recognized that abruptly closing existing reactors would lead to a spike in emissions. But U.S. plants are aging and grappling with a variety of challenges. In recent years, their economic viability has been threatened by cheap, fracked natural gas. Safety regulations introduced after the meltdowns at Japan’s Fukushima Daiichi nuclear plant, in 2011, have increased costs, and, in states such as California, legislation prioritizes renewables (the costs of which have also fallen steeply). Since 2013, eleven American reactors have been retired; the lost electricity has largely been replaced through the burning of fossil fuels. At least eight more closures, including Diablo Canyon’s, are planned. In a 2018 report, the Union of Concerned Scientists concluded that “closing the at-risk plants early could result in a cumulative 4 to 6 percent increase in US power sector carbon emissions by 2035.” The past decade has seen the rise of a contingent of strongly pro-nuclear environmentalists. In 2007, Shellenberger and his colleague Ted Nordhaus co-founded the Breakthrough Institute, a Bay Area think tank known for its heterodox, “ecomodernist” approach to environmental problems. The organization, which presents itself as more pragmatic than the mainstream environmental movement, supports nuclear power alongside G.M.O.s and agricultural intensification. Other pro-nuclear groups include Third Way, a center-left think tank, and Good Energy Collective, a policy-research organization. (Shellenberger left the Breakthrough Institute, in 2015, and founded Environmental Progress, partly to focus more on efforts to save existing plants.) The 2011 Fukushima disaster shifted the landscape of opinion, but not in entirely predictable ways. Immediately after Fukushima, anti-nuclear sentiment surged; Japan began to shutter its nuclear plants, as did Germany. And yet, as Carolyn Kormann has written, studies have found few health risks connected to radiation exposure in Japan in the wake of the accident. (The evacuation itself was associated with more than a thousand deaths, as well as a great deal of economic disruption.) Pro-nuclear advocates now point out that, after retiring some of their nuclear plants, Japan and Germany have become increasingly reliant on coal. Heather Hoff watched news footage of the Fukushima disaster while at Diablo Canyon. What she saw resembled the scenarios she had learned about in training—situations that she had prepared for but never expected to face. “My heart instantly filled with fear,” she later wrote, on the Mothers for Nuclear Web site. For a time, her confidence in nuclear power was shaken. But, as more information emerged, she came to believe that the accident was not as cataclysmic as it had initially appeared to be. Eventually, Hoff concluded that the incident was an opportunity to learn how to improve nuclear power, not a reason to give up on it. She and Zaitz visited the site in 2018. They saw black plastic bags of contaminated soil heaped on the roadside, and ate the local fish. Afterward, they both blogged about the experience. Zaitz wrote that she understood the fear provoked by radiation, “with its deep roots in the horrendous human impacts caused by the atomic bomb.” Pro-nuclear environmentalists often tell a conversion story, describing the moment when they began to see nuclear power not as something that could destroy the world but as something that could save it. They argue that much of what we think we know about nuclear energy is wrong. Instead of being the most dangerous energy source, it is one of the safest, linked with far fewer deaths per terawatt-hour than all fossil fuels. We perceive nuclear waste as uniquely hazardous, but, while waste from oil, natural gas, and coal is spewed into the atmosphere as greenhouse gases and as other forms of pollution, spent nuclear-fuel rods, which are solid, are contained in concrete casks or cooling pools, where they are monitored and prevented from causing harm. (The question of long-term storage remains fraught.) Most nuclear enthusiasts believe that renewables have a role to play in the energy system of the future. But they are skeptical of the premise that renewables alone can reliably power modern societies. And—in contrast to an environmental movement that has historically advocated the reduction of energy demand—pro-nuclear groups tend to focus more on the value that abundant nuclear energy could have around the world. Charlyne Smith, a twenty-five-year-old Ph.D. candidate in nuclear engineering at the University of Florida, who shared her story on the Mothers for Nuclear Web site, grew up in rural Jamaica, where she had firsthand experience of “energy poverty.” During hurricanes, she told me, no one knew when the electricity would come back; food would spoil in the fridge. Smith learned about nuclear power as an undergraduate and decided to enter the field, with the goal of bringing reactors to the Caribbean. She is not naïve about the risks: she is writing a dissertation on nuclear proliferation. But, she says, “Waste and radiation—those are risks that are minimizable. Proliferation of nuclear material—that risk is minimizable. Versus what you can get out of nuclear energy, weighing the pros and cons. I strongly believe that nuclear energy can solve countless problems.” The pro-nuclear community is small and fractious. There are debates about how large a role renewables should play and about whether to focus on preserving existing plants or developing advanced reactors, which have the potential to shut down automatically in the event of overheating and to run on spent fuel. (These reactors are still in the experimental phase.) There are also differences in rhetoric. At one end of the spectrum is Shellenberger, who seems to see mainstream environmentalists as his main adversaries; his newest book is titled “Apocalypse Never: Why Environmental Alarmism Hurts Us All.” His recent commentary decrying what he calls the climate scare has been widely circulated in right-wing circles and has perplexed some pro-nuclear allies. At the other end is Good Energy Collective, co-founded, recently, by Jessica Lovering, Shellenberger’s former colleague at the Breakthrough Institute. Her organization situates itself specifically on the progressive left, and is attempting to ally itself with the broader environmental movement and with activists focussed on social and racial justice. Mothers for Nuclear falls somewhere in between: their tone is less combative than Shellenberger’s, but Hoff and Zaitz often seem frustrated with anti-nuclear arguments and, in their social media feeds, point out the downsides of renewables—an emphasis that may turn off some of the people they are trying to persuade. (They believe that nuclear power should do most of the work of decarbonization, supplemented by renewables.) Nuclear energy scrambles our usual tribal allegiances. In Congress, Democratic Senators Cory Booker and Sheldon Whitehouse have co-sponsored a bill with Republican Senators John Barrasso and Mike Crapo that would invest in advanced nuclear technology and provide support for existing plants that are at risk of closure; a climate platform drafted by John Kerry and Alexandria Ocasio-Cortez included a plan to “create cost-effective pathways” for developing innovative reactors. And yet some environmental organizations, including Greenpeace and Climate Justice Alliance, deplore nuclear energy as unsafe and expensive. Perhaps most telling is the ambivalence that some groups express. Although the Union of Concerned Scientists has warned about the climate impacts of shutting down nuclear facilities, it has historically sounded the alarm about nuclear risk. Ed Lyman, its director of nuclear-power safety, told me that, because “there are so many uncertainties associated with nuclear safety analysis,” it’s “very hard to make a conclusion about whether it’s safe or not.” He noted, dispiritingly, that climate change could increase the hazards at nuclear plants, which will have to contend with more extreme weather events. When Hoff and Zaitz officially launched Mothers for Nuclear, on Earth Day, 2016, they had to figure out how to tell their story and to change minds. The standard images of renewables—gleaming solar panels, elegant wind turbines in green fields—are welcoming, even glamorous. It seemed to Hoff and Zaitz that, by comparison, the nuclear industry had done a terrible job at public relations. By emphasizing safety, they thought, the industry had activated fears. Airlines don’t advertise by touting their safety records. It might be better to unapologetically celebrate nuclear energy for its strengths. They gave talks at schools and conferences, shared stories on their Web site, posted on social media, and eventually started chapters in other countries. Iida Ruishalme, a Finnish cell biologist who lives in Switzerland and now serves as Mothers for Nuclear’s director of European operations, told me that she was drawn to the organization, in part, because of its appeal to emotion. The widespread impression, she said, is that “people who like nuclear are old white dudes who like it because it’s technically cool.” Mothers for Nuclear offered “this very emotional, very caring point of view,” she said. “The motivation comes from wanting to make it better for our children.” Ruishalme said that online commenters often tell her that the group is “clearly propaganda, a lobbyist front, not sincere—because it’s so preposterous to think that mothers would actually do this.” On the organization’s Web site, a photo montage of women and children is accompanied by a caption clarifying that they are pictures of real people who support the group—not stock images. Among opponents, there is a long-standing assumption that anyone who promotes nuclear power must be a shill. The name “Mothers for Nuclear” sounds so much like something dreamed up by industry executives that it can elicit suspicion, even anger, in those who are anti-nuclear. The organization is entirely volunteer-run, with a tiny budget, and has not accepted donations from companies. But Hoff and Zaitz work at a nuclear plant and have been flown to give talks at industry-sponsored events; Mothers for Nuclear has received small donations from others who work in the industry. There is no denying the conflict of interest posed by their employment; even within the pro-nuclear community, their industry ties provoke uneasiness. Nordhaus, the executive director of the Breakthrough Institute, wrote in an e-mail that, although he thinks Hoff and Zaitz are “well-intentioned,” nuclear advocacy should be independent of what he called “the legacy industry.” (The Breakthrough Institute has a policy against accepting money from energy interests.) Yet, from another angle, their connection to industry may be an asset. “Where they’ve been successful is coming at it from a personal perspective,” Jessica Lovering, the co-founder of Good Energy Collective, told me. Their approach to telling their stories, as outdoorsy, hippie moms, “humanizes the industry,” she said. On a drizzly morning in May, 2019, when such visits were possible, Hoff and Zaitz offered me a tour of their plant. Hoff picked me up from my hotel in San Luis Obispo in her slate-gray electric Ford Focus, adorned with a “Split Don’t Emit” bumper sticker. While we waited for Zaitz at a café a few blocks away, Hoff told me about the lavender pendant hanging around her neck. Crafted for her by an artist she knew in Arizona, it was made partly of uranium glass, an old-fashioned material that has a touch of uranium added in for aesthetic purposes. “I wear it as a demonstration—radiation is not necessarily dangerous,” she said. Like many nuclear advocates, Hoff believes that the fears provoked by radiation are often unfounded or based on information that is not contextualized. A CT scan of the abdomen involves about ten times as much radiation exposure as the average nuclear worker gets in a year. Some scientists argue that no level of radiation exposure is safe, but others doubt that exposure below a certain threshold causes harm, and note that we are all exposed to natural “background” radiation in daily life. (Uranium glass emits a near-negligible amount.) Hoff and Zaitz believe that panic about radiation from nuclear energy has, cumulatively, caused more harm than the radiation itself. After Zaitz arrived, we set out for Diablo Canyon. I rode up front; Zaitz sat in the back, pumping breast milk for her year-old daughter. The light rain had stopped, but mist still hung in the air. We passed through the town of Avila Beach, driving alongside the ocean. To our left, aquamarine water sparkled. On our right lay gently sloping terrain of grasses, sagebrush, wildflowers, and shrubs. The facility sits amid twelve thousand acres of otherwise unoccupied seaside land. Along the curving road, a sign proclaimed “Safety Is No Accident.” In the distance, the two massive containment domes rose above a cluster of shorter structures. We pulled into the parking lot. In one of the outbuildings, I handed over my passport, then placed my jacket and bag in a plastic bin for an X-ray. I walked through a metal detector, then stood under the arch of a “puffer machine,” which blasted me with air, shaking loose particles and analyzing them for traces of explosives. Once I’d been cleared, we walked upstairs to Hoff’s office, where the two women exchanged greetings with a few co-workers. We put on safety glasses and hard hats before entering “the bridge,” a narrow corridor with large windows that connects the administration building to the turbine hall. Through the windows, we could see the ocean, where water was continually cycling into and out of the plant. A security guard, armed with a handgun and a rifle, and wearing a red backpack, sauntered by. The turbine hall, a vast space with a soaring, arched ceiling, was dominated by two large generators. Outside, within the two containment domes, uranium atoms were splitting apart in a chain reaction, heating water to more than six hundred degrees Fahrenheit; the steam spun the turbines, which in turn drove the generators. The resulting electricity would bring power to about three million Californians. Warm air rushed noisily around us. Through the din, Hoff explained different parts of the system: the pipes, the springs that supported them, the condenser, which takes wet vapor from the turbine exhaust and turns it back into liquid. Vending machines selling Pepsi and Chex Mix stood against one wall. I wasn’t allowed to take photos, but Hoff snapped a few of me and Zaitz. We smiled as if we were at Disneyland. In June, 2016, not long after the formation of Mothers for Nuclear, P.G. & E. announced that it would not renew its operating licenses: the reactors at Diablo Canyon would cease operations in 2024 and 2025, respectively. The company said that its decision was based largely on economic considerations. Customer demand was declining, in part because of the growing popularity of a system called community-choice aggregation, in which localities can choose their energy sources; often they choose wind or solar farms (though they still need to rely on natural gas at night, when solar is unavailable). The year before, California had passed Senate Bill 350, which requires the state to derive half of its energy from renewable sources by 2030; since P.G. & E. would be legally required to increase its procurement of renewable energy, it could end up with more electricity than it needed if it kept Diablo Canyon online. The environmental groups that supported P.G. & E.’s plan, including the Natural Resources Defense Council and Friends of the Earth, see it as a model for gradually transitioning to a grid fed entirely by renewable energy. P.G. & E. has pledged to replace Diablo Canyon with other low-carbon energy sources. And yet energy storage remains a major challenge. Even if P.G. & E. does manage to fill the gap without help from natural gas—a heavy lift—some argue that, given California’s ambitious climate goals, the state should be adding to its total portfolio of low-carbon energy rather than subtracting from it. Experts differ on the wisdom of the choice. Steven Chu, the Nobel Prize-winning physicist who served as President Barack Obama’s Secretary of Energy, told me that he had urged P.G. & E. not to decommission the plant. “It’s really the last twenty to thirty per cent of electricity where it’s going to be hard to go a hundred per cent renewable,” he said. Daniel Kammen, a physicist and a professor of nuclear energy at the University of California, Berkeley, however, was more sanguine. Although he is not opposed to nuclear power, or even to keeping Diablo Canyon open, he said, “We don’t need nuclear, and we certainly can get to a zero-carbon future without nuclear. The mixture of other renewables means you don’t have to go there.” Hoff and Zaitz are not especially optimistic about the future of Diablo Canyon, but they hope that, between now and the planned closure, P.G. & E. and state officials can be persuaded to reverse course. They seek to recruit ordinary Californians to their cause. After touring the plant, I accompanied them to a radio studio, where they were scheduled to be guests on Dave Congalton Hometown Radio, a popular local talk show. On the air, Hoff explained who they were. “Mothers for Nuclear offers a different voice,” she said. “Nuclear power plants are run by lots of men, and women have been more scared of nuclear energy. We’re here to offer the motherly side of nuclear—nuclear for the future, for our children, for the planet.” The phone lines lit up. The first couple of calls were favorable. “It’s kind of nice to hear a little bit of sanity about nuclear power, for a change,” a caller named John said. But then Pete, a listener who said that he had protested the construction of Diablo Canyon back in the early eighties, brought up nuclear waste. “There’s been numerous efforts to put it here, put it there, put it in barrels, bury it in the sea, bury it in deep caves—this, that, the other thing,” he said. “I don’t think any really good solution has even come up.” “Pete, where do you put your garbage?” Hoff asked. “Where do you put your plastic waste?” “That’s not radioactive!” “It’s still really damaging to the environment,” Hoff said. “An accident at a nuclear plant is a lot worse than an explosion at an oil plant,” Pete said. Zaitz jumped in. “The surprising thing, Pete, that we found out is that nuclear is actually the safest way to make reliable electricity when you look at even the consequences of the worst accidents we’ve ever had,” she said. “Any other energy source ends up, in the long run, killing more people, whether it’s due to air pollution, whether it’s due to industrial accidents. Air pollution kills about eight million people per year.” As the conversation continued, Hoff and Zaitz held their own, but it seemed unlikely that many minds would be changed decisively. In trying to plan a carbon-free future, we are faced with imperfect choices and innumerable unknowns. In such situations, we typically go with our guts. Gut feelings are hard to alter. And yet, especially for younger people, nuclear power may not elicit visceral fears. Many people who did not grow up with the threat of a nuclear holocaust now face a future of climate chaos. Many lie awake at night imagining not meltdowns but lethal heat waves and calving glaciers; they dread life on an inexorably less hospitable planet. Since I first met with Hoff and Zaitz, the coronavirus pandemic has upended the world. At Diablo Canyon, the comparatively small fraction of the plant’s workers who need to be on site—security guards, control-room operators, and the like—are now doing so in masks, and with other safety protocols in place; Hoff and Zaitz have been working from home. Meanwhile, last summer, wildfires set the West Coast ablaze. For Hoff and Zaitz, both crises have reinforced their existing beliefs. Evidence that air pollution exacerbates vulnerability to covid-19 is yet another reason to move away from fossil fuels; the importance of ventilators and other devices at hospitals underscores the need for reliable, around-the-clock electricity. Last August, when thick smoke blocked the sun in parts of California, solar output in those areas temporarily plummeted. Rolling blackouts have raised questions about how California’s grid will function after Diablo Canyon is shut down. In May, the office of the California Independent System Operator, which is responsible for maintaining the grid’s reliability, filed comments to the state’s Public Utilities Commission. Its modelling, the office reported, showed that “incremental resource needs may be much greater than originally anticipated and that the system hits a critical inflection point after Diablo Canyon retires.” At the same time, the plant’s outsized role is not without drawbacks. The reactors periodically need to be taken offline for maintenance, withdrawing a substantial amount of electricity from the grid. Our energy system is in flux. There are innovations under way in the renewables sphere—advances in battery storage, demand management, and regional integration—which should help overcome the challenges of intermittency. Nuclear scientists, for their part, are working on smaller, more nimble nuclear reactors. There are complex economic considerations, which are inseparable from policy—for example, nuclear power would immediately become more competitive if we had a carbon tax. And there are huge risks no matter what we do. To be fervently pro-nuclear, in the manner of Hoff and Zaitz, is to see in the peaceful splitting of the atom something almost miraculous. It is to see an energy source that has been steadily providing low-carbon electricity for decades—doing vastly more good than harm, saving vastly more lives than it has taken—but which has received little credit and instead been maligned. It is to believe that the most significant problem with nuclear power, by far, is public perception. Like the anti-nuclear world view—and perhaps partly in response to it—the pro-nuclear world view can edge toward dogmatism. Hoff and Zaitz certainly seem readier to tout studies that confirm their views, and reluctant to acknowledge any flaws that nuclear energy may have. Still, even if one does not embrace nuclear power to the same extent, one can recognize its past contributions and question the wisdom of counting it out in the future. One of the last times I spoke with Zaitz, she noted that a lot of people seemed to be feeling discouraged at this moment, overwhelmed by the scale of the challenges ahead. But she counselled against despair. “The hopeful way to go into that is, ‘Oh, wow, we actually have technology that can do this,’ ” she said. “And that’s nuclear. And so I’d rather stay hopeful.”

Hello everyone, this is Jason Jacobs and welcome to My Climate Journey. This show follows my journey to interview a wide range of guests to better understand and make sense of the formidable problem of climate change and try to figure out how people like you and I can help.

Today's guest is Daniel Kammen. Dr. Kammen is a distinguished professor of energy at the University of California Berkeley, and has parallel appointments in the energy and resources group, the Goldman School of Public Policy and the Department of Nuclear Engineering. He was also appointed the first environment and climate partnership for the Americas Fellow by secretary of state Hillary Clinton in April, 2010. He's the founding director of the Renewable and Appropriate Energy Laboratory, co-director of the Berkeley Institute of the Environment and Director of the Transportation Sustainability Research Center. He's founded or is on the board of over 10 companies and [00:02:00] has served the state of California and the U.S. federal government in expert and advisory capacities.

Now his bio goes on and on from there, so I was both very excited and also a little intimidated about this discussion. But Dan is a super guy and we have a long form discussion in this episode about Dan's background, how his perspective on the problem of climate change has evolved over the years, how he thinks about the problem today, the best path or paths forward to help us address the problem. And also some of the issues and barriers that are holding us back and what we might do about them. Dan's perspective is particularly unique given the diverse background that he brings, which I find super interesting given the systems nature of the problem. Daniel Kammen, welcome to the show.

Daniel Kammen:  Oh, thanks for having me on.

Jason Jacobs:  Thanks for being here. I have to say we've never spoken before, but from the size of your bio and the contents of your bio, I am [00:03:00] intimidated to have this discussion.

Daniel Kammen:  I don't think so. Academic bios are designed to be long for reasons I don't understand [laughs] so.

Jason Jacobs:  Academic but you've got an interesting blend because there's an academic component, there's a published author component, there's a private sector component, there's a government component. And I think those types of discussions in those types of backgrounds are immensely interesting for me given the systems nature of the problems that we're dealing with.

Daniel Kammen:  No, I agree. I mean, that's why having an academic job is great because it allows you to keep some of the research and investigative threads going through good and bad funding times. But it's ultimately for me the implementation of climate solutions, that is how I kind of define my career. So yeah, bouncing back between those different worlds is really what I like.

Jason Jacobs:  Yeah. No. And I, although I've been focused on climate a heck of a lot less long as you, I kind of think similarly people say like, so you're focused on the podcast or so you're focused on the community or you're focused on investing or so [00:04:00] you're focused on advising early stage companies or things like that. And it's like, well actually no, I'm focused on figuring out how to have the maximum impact on the problem of climate change. And this portfolio of things is constantly in flux and evolving as I'm figuring out how to grow the impact that I can have in this growing web of people that are involved in my climate journey community can have on the problem, but I'm not web to any one kind of functioning or occupation or anything like that. I'm just web to having the biggest impact that I can.

Daniel Kammen:  Getting something done. Yeah.

Jason Jacobs:  Yeah. So how would you, I mean, it's, given the diversity of your experience, how would you describe professional you and what you do?

Daniel Kammen:  So I started out as a physicist, I went through undergraduate and graduate school on physics, but I hadn't decided to be a professor. Actually my interests were divided between physics research and becoming an astronaut and being an astronaut didn't work out because I failed the vision test when I went off to the NASA testing grounds. And so that pushed me towards kind of the research side. And so I [00:05:00] began my academic career first and physics, but then working on energy problems mainly on the technology side. So better longer lasting lower costs, solar cells, hardware to go into energy storage systems. But the more you do that, the more that leads you to the astronaut world, the, we don't just research it we want to do, right? The joke is that there's, in Jurassic Park they said there's two kinds of kids. Those who wanna grow up to be astronomers, those want to be astronauts. And I always like to think that it's both.

And so the more you work on low carbon energy technologies, particularly when I started several decades ago when essentially none of them were affordable. We're now in a world where all of them are affordable and that pushes you even more towards understanding the systems approach. And so in my academic work here at University California, Berkeley I have teams working on off-grid power for Southeast Asia, for East Africa. And I have looking at systems integration. And then I have a [00:06:00] whole bunch of postdocs and fellows that come through that are really interested in the implementation. Whether that's spinning out of my laboratory to form a company or to set up a nonprofit to do energy and conflict regions in Africa, or as people who really want to learn enough technical material so that when they go into companies or state or federal office they feel like they're really on top of the science and engineering.

And so my lab is really a mixture of those things and the projects and opportunities we have will range from working with very small off-grid communities, native American communities in the United States, or very small coastal communities in Kenya, Nicaragua, all the way up to trying to redesign the power system at the scale of the U.S. or China. And so my physics background has morphed into some mixture of physics, electrical engineering, policy and as a result, I probably have the most schizophrenia faculty position than anyone I know at Berkeley.

[00:07:00] I'm in the energy and resources group where I'm chair, I'm in the Goldman School Policy and I'm in the Department of Nuclear Engineering. And I definitely know I have too many meetings as a result, but I wouldn't want it any other way because I feel like that mixture of science of decarbonization, energy technology options, and policy really fits my work at the university. And when I go into public service, I go back and forth between jobs at the state department, a world bank, California government. And so that mix really describes where I feel like you can really maximize getting things done on. Not just a low carbon economy, but an increasingly one that's focused on equity and equality.

Jason Jacobs:  So it's my impression and granted, I caution myself about my impressions because in 2003 I took a month before grad school and I went backpacking around Europe and I only had a month to cover way more ground than we could possibly fit in a month. And so what we would do is we would make a stop in each place. We would go to Barcelona for example, or Madrid or Lisbon or places like that. And [00:08:00] as we did, we were just land in one part of the city, we wouldn't have a plan, we would stay 24 or 48 hours and then we would move to the next. And that would be our impression of the city. But I think about Boston where I live and it's like, if you happen to overnight in Allston versus Beacon Hill versus Kendall Square, you know, versus Harvard Square or Dorchester, [inaudible 00:08:17] or any of these places, you get a very different impression of the city.

And so that's kind of been my experience with climate change, right? I'm so broad in that but I get a little sliver of all these different things. That was my preamble. My impression though, is that when it comes to energy there's like renewables and everything that's going on over there with the grid and clean energy transition and things like that. And then nuclear of course, is an incredibly prolific energy source, but it's tends to be of like a different group of people or different discussion kind of siloed off doing its own thing. Is that your impression as well?

Daniel Kammen:  I think it was, there's no question that nuclear was so-called born secret. It came out of war efforts and the early civilian reactors, the first civilian reactor [00:09:00] was in shipping port Pennsylvania. These were really spin out of the military industrial complex, not value judgment, but the military industrial world. And for decades that was really how people saw nuclear potentially fitting in. It was the technology that was different because it is both energy dense, but it also comes with some very large risks. But what's happened in the last decade and a half is that a whole suite of technologies that the U.S. government, the French government, the Russian government, didn't have the bandwidth to research, bandwidth both people and money have found private sector backers. And whether those end up being things that are useful in the safe low cost commercial world of [trust ROL 00:09:47] energy, or whether there are things that end up being better for space missions and other features is something that we're gonna see.

But most of the high profile billionaires that you hear about these days have made [00:10:00] some pitch into nuclear. So it has privatized very similar to how the space launch world that was only governments for long time. Now has the Elon Musk, the Richard Branson, it's now got a real private sector flavor. And so nuclear is in this point of transition but in terms of climate change, what we don't know yet is will nuclear undertake this transition and become a player in the climate change story or whether it will just be competitive our long-term future. And I say just, I don't mean in a bad way but we know that the climate change story will be decided between now and 2050. And whether nuclear becomes a different player in that coming 30 years is something that no one can say.

There are people who have plans to scale it up but right now the least cost clean energy technologies are not nuclear. They are solar, wind, increasing the energy storage, geothermal [00:11:00] power and so whether nuclear becomes a partner in that low carbon world is something that we're gonna see. I believe nuclear will be very important in the long-term after I'm retired and gone. But whether it's a real player in the climate change story where we have only a few decades left, that's still a question.

Jason Jacobs:  Why does he get so much backlash and how much of that backlash has founded?

Daniel Kammen:  That's a hard question. It gets a lot of backlash for the obvious reasons that we've had some spectacular disasters in the nuclear world. From Chernobyl to Three Mile Island to Fukushima, the downsides are really severe. Whether it's justified or not is a much more complicated question because it very much depends on what's your perspective. Many more people have died and many more animals and ecosystems have died from coal than nuclear, but each nuclear accident is so horrific that it changes the landscape for the [00:12:00] technology going forward. And so nuclear's role is really this complex one. Because humans are really bad at understanding and thinking about low probability, high consequence events. And while coal is like the creeping cancer that eats away at our health, ecosystem's health, when nuclear has a bad day it's a doozy. And so I think that's really the position that nuclear astraddle and it's why nuclear for decades was a government only enterprise.

And obviously there were private companies but they were very tied to the government set up. Now nuclear is trying something new and it is a big experiment. We don't know whether small modular reactors or uranium thorium mixed reactors are going to be cost-effective and significantly safer and cheaper. So they get to play in a world right now where, when you look at the low carbon future, what solar has done is so [00:13:00] dramatic. And most of my career as a energy physicist has actually been with solar and storage. And so when I started grad school solar was the most expensive of all the technologies.

Today in 2020 solar in many parts of the world is the cheapest. I don't mean with subsidies, I mean just simply you buy the hardware, you install it, you buy energy storage to go with it. And that is the least cost technology for many places in many parts of the world. That transition it's just kind of remarkable, it means that solar has gone to scale in a way that some very smart people were simply dead wrong on decades ago. And so every time I hear someone saying solar is getting at the end of its learning or improvement curve, I say, don't count out the technology that has made the global biggest change over the past decades.

Jason Jacobs:  Is it true that most people either work on solar or renewables or nuclear, [00:14:00] but that you kind of have to pick a side like you work on both, which seems like a rare breed.

Daniel Kammen:  It generally is you're right. That people have generally picked aside and I would even go further, that frequently I have seen people who are strongly in the solar camp devoting a great deal of effort to attacking the nuclear camp and people in nuclear, I think have gone overboard in attacking renewables. Whereas the enemy is climate change and the enemy is fossil fuels because that economy, however you think about what it got us to today, simply can't be the energy system of the future. And so I think you're right, people like me that work in both and physicists have kind of a nice training to work in both solar and nuclear.

And I always joke that of course, solar is nuclear. It happens to be 93 million miles away but solar of course is fusion and so I see a natural match between the two. But I think you have to have that kind [00:15:00] of physics and policy kind of love like I have to see them as potentially real partners.

Jason Jacobs:  To the people that advocate that 100% renewables can get us there and should get us there in any talk of any kind of portfolio that doesn't just raise their focus on that is a distraction that slows our progress. How do you react to that?

Daniel Kammen:  Well, so I mean, there's no question that 100% renewables is possible. I've done a lot of research, my lab works on scenarios to get the U.S., China, Mexico, Kenya, Bangladesh, Morocco to 100% renewables. And in many cases where the technology mix is improving enough, the climate favors that you can do that. It's also a case that we are not today ready to think about a solar and wind only world, but solar and wind plus storage, plus geothermal, plus potentially [00:16:00] nuclear. I'm much more bullish today on keeping the current nuclear plants operating than on picking the winner of the emerging technologies. But all the plants we have today and there's about 420 nuclear plants in operation around the world, 100 of them are in the United States, 60 in France, so those two countries alone dominate who has nuclear.

All those plants have to be retired by the mid century 2050 reaching number when we've got to be on the clean economy. And so that means that for nuclear to have a role, it will need to not only replace 420 plants worldwide which the industry is not ready for, but expand that share. And that's why I say that 100% clean energy world we could get there with the classic renewables and storage alone. It just makes the job of space heating and industry and override the of things quite challenging. And so for me, not investigating a portfolio would be irresponsible.

Jason Jacobs:  How much [00:17:00] is not having an answer to long duration storage holding us back. And how realistic is it that we'll ever have an answer too long duration i.e seasonal and beyond storage?

Daniel Kammen:  You're talking about renewable storage, just to make sure 'cause some people, when you say storage and long duration they're thinking nuclear.

Jason Jacobs:  Yeah. Intermittency for renewables.

Daniel Kammen:  Yeah. So just like I said, don't sell solar short, don't sell storage short and for many reasons it's the same thing. Solar has this huge benefit that there's multiple material science, there's multiple technologies, there's traditional crystal in, there's thin film, there's organic solar cells, there's quantum dots, there's [photovoltaic 00:17:40]. Some of those are commercial today, some of those are coming. Same thing is true for storage. When I used to go and testify to the U.S. [inaudible 00:17:48] 15, 20 years ago around something like air quality and vehicle mile per gallon for example. You would get someone saying, well, cars are never gonna get much more efficient. We can [00:18:00] maybe have some small increases, but we're not gonna do much better.

And that's really, people have said that about energy storage. They said, well, we have lead acid batteries, car batteries, truck batteries. They're not gonna meet the challenge and everything else is too expensive. Now we have lithium ion batteries for our devices and they are very cost-effective. They have some challenges and materials and lifetimes, but storage has now diversified so that there's lithium ion, nickel metal hydride, liquid flow batteries. We have mechanical batteries like flywheels, we have physical battery systems. There are companies that now essentially move rock uphill or up cranes, and they have storage that's mechanical. And so storage is 10 years behind where solar was in the sense it is improving and it's diversity is its biggest strength.

Jason Jacobs:  And how much of [00:19:00] what we need to achieve 100% renewables exist today and if there's anything missing, what's missing?

Daniel Kammen:  Well, I would say we have everything we need today in the sense that we have sufficient opportunities for expanded solar and wind. And storage while it's not as cheap as we want it to be it has met and exceeded all of the national milestones. And so what I would say we need is more and lower cost storage. And more and lower costs go together, for every technology we see these learning or experience curves where the more you build and deploy the cheaper it gets. And so storage is there, but we would pay a premium if we built out everything overnight. And that's actually why I am so pleased to see Vice President Biden's plan, where he initially was saying 2050 was his target year for 100% clean energy. But in the last month he's up that to say 2035. And that was a very shrewd [00:20:00] choice because it reflects where we are with the cost declines of renewables, the cost declines of storage.

And so we're there in terms of having the tools, but we want to make clean energy available for all. So a ubiquitous justice argument needs to go in there. And so for that, we need continuing innovation. We need the R&D pipeline to be reinvigorated. We need more different products, technologies, and we need more systems thinking because in many cases we're wasting so much energy through inefficiency, through transmission systems that lose energy, that we are not living up to the best of our technologies but we need to make those better as well. So I would say this is a co-evolution that will us there. But if we were charged with you must replace all fossil fuel overnight, we could do it, it would just be prohibitively expensive.

Jason Jacobs:  And when you take a step back from technology innovation, and you just look at the overall [00:21:00] transition. Are there key levers that if this one or handful of things happens, they'll have an outsize impact more than any other thing, or is it more like there's tens, hundreds, thousands of things that need to happen, and they all help push the Boulder down the mountain and we need it all and shouldn't have favorites.

Daniel Kammen:  Well, I think we shouldn't have favorites in the sense that all of these technologies, these low carbon ones are a benefit, but there are still some levers there that are critically important. Now that solar and wind have gotten cheaper than fossil fuels for much of the country and much of the world, we're actually seeing something that was obvious to economist, but what was not obvious to kind of sustainability thinkers. And that is just by having a lower cost Gizmo. Here's a little off-grid solar light, solar panel on the front, LED light on the back and then a lithium ion battery. So here's an example of something that needs to get [00:22:00] cheaper, but there are some really critical individual things that we should be doing.

The biggest one is that the, the world subsidizes fossil fuels to a huge degree. Depending whose math it's between a half a trillion and $5 trillion a year, the governments of the world put into subsidizing coal oil and gas. And to put that number in perspective the global renewable energy industry has invested about two and a half trillion over the past decade. And yet we now currently subsidize fossil fuels by about that same amount each year. So getting rid of fossil fuel subsidies would be the number one thing on the agenda and you can, of course either do it by getting rid of those subsidies. But many of those are baked into the giveaways that governments give to many companies, or you could think about increasing the carbon price. And so removing fossil fuel subsidies and, or getting rid of, or, and adding a price on [00:23:00] carbon, those two are at the top of my list because they would reset the playing field.

The other thing which I think is central to getting us to this clean economy is that we've treated climate change as kind of an academic exercise. There are lots and lots of academic groups, think tanks that write about what we need to do, and those are all true. But climate change up until recently up until the efforts of Greta Thunberg and the youth, and some of the real alarmists has not been a movement and the next stage needs to be a movement. And I think we're seeing that now, and making climate change and social and racial justice kind of co-equal partners, to me that's an example of moving from a critical scientific issue to a movement.

Jason Jacobs:  And you mentioned getting rid of fossil fuel subsidies and a price on carbon is two key things that we could do. I understand that, that those would both be impactful things to do but, I mean, how realistic is it [00:24:00] that we can do either of those things anytime soon, regardless of who wins in the upcoming election?

Daniel Kammen:  This is really become an issue where the U.S. is the real outlier. Europe has had a price of carbon for quite some time. Well, over a decade, it has some problems, the price has fluctuated. China is launching a price of carbon that will of course be the biggest carbon market in the world. And China is launching theirs at just about the exact same price that we have in California, which is about 20 U.S. dollars a ton. That's on the low end of the range we think is needed to tip whole economies but Europe, California, China, being aligned on this means that the federal argument in the United States, because certainly Republicans in the U.S. are against a carbon price and some Democrats are too.

And so where I say, I would like to see a carbon price, yes. Do I think we needed to get there? No, because I think that removing these fossil fuel subsidies would be essentially the equivalent and because clean [00:25:00] energy has become so inexpensive, we really need to unlock innovation for private companies to stay level, utility, planners and regulators that often don't see clean energy as cheap as it is because they're so invest in the old way of doing things.

And so opening up markets to clean energy, rewarding cities that protect human health, which often means the health of underprivileged people and minorities. Those are all things that we can put into place without having to spend all our time obsessing about a carbon price or the subsidies. And those things as well would move clean energy into the central part of our economy. And every day you hear a story the Coal Museum in Kentucky just put solar panels on the roof. We have wild cat, natural gas frackers that are using some of their land also do solar. Even in the industries that are the most ideologically opposed to clean energy, we're seeing that transition.

And then you look at places like [00:26:00] California, we've been running 60 to 75% on clean energy every day for the last month. Costa Rica just has run for almost 150 days straight with clean energy. Same thing is happening in England. And so we are seeing that just on the energy infrastructure generation side clean energy can get there. And that's even before we get to the jobs store and there are many, many more jobs available per dollar invested in renewables than in fossil fuels. And so if you combine lower costs with more jobs the fact that clean energy has become such an ideological football in the United States and really bucking the global transition, which is seeing clean energy as the natural way to go.

Jason Jacobs:  And I mean, we've talked about innovation and we've talked about certain specific policy initiatives like the fossil fuel subsidies or a price on carbon. But if you look bigger picture at things like capitalism, and [00:27:00] even just like the way that we're used to living our lives, I mean, can those just kinda go on as they do except swapping out things that are clean or do we need dramatic changes or somewhere in between? Like, I guess, how do the things we've been talking about on the technology and policy side fit into the bigger picture and what are the implications for life as we know it, if any?

Daniel Kammen:  The preface that I would say that innovation, new companies, new business models is all about the future. Whereas politics is generally about the past, because politics is generally about who is rich and in powered today. Whereas every startup and even big companies that wanna build new markets, they're all about the future. And so innovation and industry I think are aligned around the clean energy economy we wanna see. And even Shell they were dramatically cutting their fossil fuel business and ramping up the renewable business. But the broader question you ask, is it enough to simply close our fossil plants and swap in renewables? That's a harder question because we have done such damage to the [00:28:00] planet. And COVID for example, there's no question that the chance of COVID type outbreaks is where it is today because we have done such damage to nature.

We have put humans in much more direct contact with many of the pathogens and illnesses. We have weakened ecosystems that keep things like this in check. And so switching from a dirty energy economy to a clean energy company has to be job one. If we don't do that, nothing else works. But on the other hand, we also need to give back land to nature. We need to think very differently about the social contract we have with each other, so that one out of seven on the planet isn't living in energy poverty. And to fix those things I think we do need the larger perspective you're talking about. And so for example, clean energy isn't just beneficial because there's no carbon emissions. It's also beneficial because by managing the supply, the life cycle of materials in our solar panels and wind turbines and [00:29:00] batteries, we can actually go to an economy which the Chinese call circular economy, we can be recycling much, much more of material.

So we don't throw away the lithium in our cell phone, we recycle it into new devices. We don't pour the effluent, the slag from our coal plants into rivers, we invest in renewable so that we can repair ecosystems. And we're now starting to see the first really hopeful signs. In California and British Columbia we're seeing serious efforts to decommission dams. Yes, they're considered low carbon, but of course, dams in many parts of the world have submerged vegetation so those methane emissions. But by thinking about the opportunities from solar and wind and geothermal and potentially nuclear to now get rid of some of the world's big dams and to return rivers to free flowing status, that's a invaluable benefit of the clean energy transition. And if we [00:30:00] don't do those things, we're not reaping all the benefits.

And so I think that an example that comes up a lot which really just encapsulates how far you can go is the transition from a gas powered car to an electric vehicle isn't just about the improvement in miles per gallon, which is all ready impressive. Gas powered cower average in the United States, 25, 28 miles per gallon, electric vehicle, even in the states powered by coal that's a vehicle getting 60, 70 miles per gallon and electric vehicle in a clean energy state like California or New York or Vermont that's a vehicle getting 120, 130 miles per gallon. So the mile per gallon equivalent is a big deal. That's just the start. Go to an electric vehicle you have no tailpipe emissions, which means you improve air quality in our cities, you cut down the bills that we get from exposure to particulates and asthma. You have co-benefits that frequently benefit the poor more than anywhere else.

And as we [00:31:00] go to a cleaner and cleaner electricity mix we don't just cite those emissions at some big power plants, we get rid of them from the system altogether except for the manufacturing, which we can also clean up. So that's this kind of win-win or kind of virtuous cycle that you start to see as you emphasize clean energy, more and more.

Jason Jacobs:  You mentioned the importance of social and racial justice both as something that needs to be addressed, but also kind of a close collaborator to the decarbonization and mutual dependencies, if you will. So what makes say that and how will that play out? How should that play out?

Daniel Kammen:  So we really didn't recognize for decades just how damaging to our most vulnerable populations our fossil fuel economy is. We have our oil refineries that are in low-income areas, and whether all are finery came first, or the low income community came [00:32:00] first, it's kind of, doesn't really matter they are co-located. Our nuclear industry has much of the waste and the mining issues and low income communities, whereas the power plants tend to go into the nicer suburbs. And so everything from the fossil fuel to how we've treated infrastructure has been something where the benefits have gone to the affluent and the harms have gone to the poor. And this is something that we are seeing very clearly in COVID. We are seeing that the quality of care goes first to the more affluent, not to lower income individuals. We have more cases of COVID on the Navajo reservation than in 13 states combined.

So we have a sad history of disproportionate benefits to the affluent and the penalty is to the poor. And what's come out of the Greta Thunberg youth climate movement to the black lives matter movement has been a real recognition that we need to rethink our infrastructure. And thankfully clean energy is aligned with [00:33:00] that mission and just a remarkable way. The ability to have low cost energy on the rooftop of homes to reduce the pollution burden in low-income communities, to not only link up how we do power generation but to do cleaner, cleaner industrial activities through renewables and potentially nuclear. These are all opportunities that the clean life cycle of renewables allows us to engage on the social justice side. And I think we're gonna look back at this period of time and we're gonna see that dealing with inequality and greed was far more difficult than dealing with dirty energy, clean energy simply beats it out.

I hate to say it in this day and age, but renewables Trump fossil fuels. What's harder for us to wrap our minds around is how do we really make this a story about social equality. Because we're more tied to our petty differences and petty grieves that I think we're gonna see [00:34:00] ourselves as tied to fossil fuels.

Jason Jacobs:  One of the things that I struggle with is that on any given day, I bounce back and forth between seeing so many things that give me cause for optimism and hope and so many things that give me cause for despair. And so it's just hard to know how we're doing. If you just take a point in time snapshot look at the math, we're not doing well at all, but if you look at all the different things that are going on that could feed each other and have virtual cycles kick in, there's a lot to be encouraged about. But then same thing in terms of the apathy, the foot dragging the sabotaging, the trade groups working maliciously behind the scenes, et cetera. So at this moment in time, so this is what? August 6th of 2020, where are we on that pendulum as you look at the world?

Daniel Kammen:  Well, I mean, I think that we're at a low not due to technology and innovation and social progress, we're at a low due to partisanship. In the '50s and early '60s for all of the problems we generated huge amounts of pollution, we isolated minorities in communities through white [00:35:00] flight, through a whole variety of things. There was a, an investment and a reliance on innovation from funding basic research and development to testing out new ideas. And in this very partisan moment we're in, the fact that in the United States there's even this argument that we should trust science or not. And the right wing of the Republican party has highlighted a real distrust for science despite the fact that the quality of their own lives is very clearly dependent on that scientific advance, from medicine and healthcare to quality of homes and jobs. And so I really look at this as a moment that we'll look back on and just shake our heads and how self destructive we were at a time when we weren't actually championing science.

The real issue is not you invest in science or not, it's how do you make science and innovation something which is a partnership, not just for [00:36:00] the all ready affluent. That were solving problems that are problems for the poor and that anyone who really feels they want to grow up to be a scientist innovator that's an available path. And we now are seeing clear, clear data that if you're Latino, if you're African-American, your chance to go into these fields over the past decades has been severely limited by systemic racism. So I see this as a really sad moment and I'm very hopeful that we will emerge from. Most of the rest of the world is emerging from it, most of the metrics around investing in science and innovation in Europe and South Korea and elsewhere are very positive.

United States right now is at a point where discussing schools and healthcare and investing in research development have become partisan divides. And it's just so painful because the people arguing against these things, their lives have been made so much better by being pro science, pro innovation. So this is the bigger problem we need to [00:37:00] fix.

Jason Jacobs:  So what do we do? I mean, granted the U.S. is only one piece. I mean, we had a bigger role historically than we'll have going forwards from a, an emission standpoint but we still have played an outsize role and we have outsized resources and might relative to much rest of the world and a responsibility. I would argue to have a leadership role in cleaning up the mess that we played a significant role in making. Certainly there's a good chunk of the country that doesn't seem to agree with that but, I mean, what path forward do you see that would give you the most hope?

Daniel Kammen:  Ironically I think that we've allowed ourselves to get here because we have marginalized people for so long. Low income minority groups across the country have gotten the short end of the stick over and over again in terms of access to the benefits of a technological policy savvy society. And we're seeing other places pass us by. And so I actually think that recognizing that many of our challenges are gonna require better [00:38:00] scientific literacy, better human literacy, in the sense of understanding that we are only as good as society as the most vulnerable and that walling off communities through technology and through physical barriers that's a recipe for decay.

Whereas investing in communities, public schools, so that equity and access are part of our equation. I actually think that helps us to solve climate and I think that solving climate helps us to recognize that societies that become as unequal as ours is, and actually Brazil in the United States are two of the most inequitable societies we have in terms of economic opportunity for low income residents and high-income. Ironically, we both right now have leaders that are going in the absolute wrong direction and so replacing both the leader in the United States and in Brazil are critical jobs to getting there societies to recognize [00:39:00] that we can innovate and we can do it in a way that's for everyone.

Right now we see that innovation, the worries of globalization, the worries of investment are things that only benefit the rich. That is the feature I think as we can undo that catch up to the rest of the world, we can actually make innovation something that everyone, no matter what your political party in persuasion is in favor of. And innovation I don't just mean hardware, I also mean social innovations. How do we integrate communities? How do we make school access more equal? How do we make air quality beneficial and not just for the rich, but for everyone, those are all climate and society interface points.

Jason Jacobs:  So January 2021 there's a new administration in place. Whoever it is, it could be an incumbent, it could be new, but there's a, administration in place for the next four years. What advice do you have for that sitting president for first 100 days and for the next four years in [00:40:00] terms of what they should be focusing on in this regard?

Daniel Kammen:  We are still gonna be working the COVID recovery at that point as well. And part of that recovery is to recognize that subsidizing pollution and inequality are not good tools for governance. And the countries that have made their COVID response also a green stimulus like South Korea and New Zealand and Denmark, they're all ready reaping the benefits. Their economies are open. Kids are to school there, they wear masks but they don't worry about this incredible burden that we're seeing here. And it's because we turned away from science and innovation.

And so whoever is the president in January I certainly think that the key advice is that by not investing in clean energy and inequity, we are throwing away social benefits. And we're throwing away opportunities to make ourselves not only [00:41:00] a faster growing economy but also more resilient against crises like COVID. Because we all know whether it's a virus, we're gonna have other huge crises going forward. Australia just live through a horrific wildfire season where up to 3 billion animals were killed. And whether it's that, or whether it's COVID or the wildfire season here, or the changing storms that are currently lashing to bit these coasts, these are all examples of the kinds of things that a pro-equity and green energy economy can actually help us to solve. So whoever is the president I really hope that's the central feature. And anyone who wants an economic recovery needs to recognize that's where you put your resources.

Jason Jacobs:  So I have one final question. I'll ask it kind of in parts which is, are you an optimist? But I wanna ask you that same question over say one year, five years, 10 years, 100 years.

Daniel Kammen:  I think actually the answer is the same for each of those, [00:42:00] because we have demonstrated through this past century that when we wanna innovate around a topic. When we invest not just in a one-off bunch of money for something one year, but when we invest regularly, basic research, more equitable schooling, health care, these are things we have examples around the planet that if you wanna do it, we can do it. The challenge is the United States has put itself in a hugely partisan box. And so I'm equally optimistic on all those timescales that you mentioned from the next month for the next 100 years, given that I think it's inevitable that we get back into investing and believing in innovation and equity. And I think if we do those two things we make the story much more workable. And we also restore the U.S. to the position it should be in of being not a global police person but being a global partner. Because the economies around the planet know they need to grow their energy mix.

[00:43:00] When President Obama and premier chief from China were partnering on climate, the U.S. was getting a huge share of those overseas energy contracts. We now need to get back to that position. The U.S. China trade war has taken us away on the short term from a really interesting evolving partnership around energy access and clean energy around the planet. So I actually think that those timescales are gonna work together when we decide we're tired of tearing each other down in United States and we're more interested in actually growing our ability to be not a bully, but a leader worldwide.

Jason Jacobs:  And I feel like we could easily extend this conversation in another hour, but given that I know you've got a call and we're coming up on time. Is there anything that I didn't ask you that I should have, or any parting words for listeners?

Daniel Kammen:  We're all gonna make our own choices in November, I hope just everyone no matter what your individual party affiliations are, that you recognize that we need to invest in U.S. infrastructure. We need to be a better partner around the world that will generate more U.S. jobs and I think that if one votes once conscious around that, we will actually see what's happened the last few years as an unfortunate digression to do partisanship, but it's much easier to build up these opportunities. So that's what I'm looking for in the coming months.

Jason Jacobs:  Great. Well, Dan, this was awesome. I wish we had another hour. Maybe we'll have you back at some point, but thank you so much for coming on the show and best of luck.

RAEL Lunch (9/​30/​2020), Alan Lamont, “Innovations in energy storage for a carbon-​​neutral economy”

In looking ahead to entirely decarbonizing the electric generation system, there is a debate about the use of nuclear generation.  One school of thought argues that nuclear will be essential to successful decarbonization, while the other feels that this can be done entirely using renewable technologies, essentially wind and solar.  This research investigates the role and value of using nuclear generation in decarbonizing the electric generation system.  Along with generation, however, storage technologies will be needed.  This study also compares the value of using batteries (expensive but efficient) to the use of ammonia (quite inefficient, but very cheap per unit of energy).  Based on the Capacity Expansion Model, the study develops an analytical function to evaluate the marginal cost of carbon reduction under various scenarios of primary generation (with and without nuclear) and storage technologies (with batteries or with ammonia).  The behaviors of the generators and storage determine the different components of this equation.  Illustrating these behaviors gives us insight as to the role of nuclear and different types of storage in decarbonizing the system.
 Alan graduated from Stanford University in 1970 with a Master’s degree in geotechnical engineering.  As a civil engineer he worked in heavy construction in Alaska and Vietnam,  Peace Corps in Venezuela in dam design, and in the Bay Area in earthquake analysis.  He returned to Stanford and completed a PhD in Engineering Economic systems in 1983.  He joined Lawrence Livermore National Laboratory in 1987,  working  energy system economics, developing and applying modeling platforms to evaluate policies and technologies for energy generation and storage.  He was also active in risk analyses  for nuclear materials production and waste disposal.  He is currently retired, but continues to work in energy systems economics to better understand strategies for reducing carbon emissions from the energy system.
