I’m thinking of comics like Marc Maron, whose act riffs off existential pain points like mortality, antisemitism, the delaminating geopolitical situation, and, of course, that multigigaton carbon elephant in the room, climate change.
“The reason we’re not more upset about the world ending environmentally, I think, is that, you know, all of us in our hearts really know that we did everything we could,” Maron deadpans. “We brought our own bags to the supermarket,” he says, then pauses a few beats.
“Yeah, that’s about it.”
No surprise that comedians are able to play our eco-dread for yuks. Comedy is often rooted in the fertile manure of uncomfortable truths: we laugh so we don’t sob. And that’s all fine and good; laughter’s a good antidote to the malaise that comes from doomscrolling our newsfeeds day in, day out.
But are we really ready to throw in the towel and laugh ourselves into oblivion? And is Maron correct? Have we really done nothing to confront our foremost environmental crisis? Hardly. True, we haven’t yet reversed the upward trend in greenhouse gas emissions, and the challenge of transitioning away from fossil fuels often seems insurmountable. Is it, though?
According to Berkeley experts interviewed for this story, there’s reason for hope that we’ll make it through the bottleneck yet. The technology is already here and improving all the time. It won’t be easy, but it is doable. Now, let’s see how:
SOLAR
If you’re looking for a peg to hang your hopes on, start with energy economics and, in particular, the price of solar panels. Costs have dropped by nearly 90 percent since 2009, driven by both improved technology and global production (particularly from China). In 1976, solar electricity cost $106 a watt; today, it costs less than 50 cents per watt. Bottom line: Solar is now competitive with fossil fuels as a means of energy production.
While solar still only accounts for 3.4 percent of domestic energy consumption, production has been growing by more than 20 percent annually over the past five years, and likely would have been higher if not for shipping and supply chain difficulties stemming from the pandemic.
Production isn’t everything, however. For widespread adoption, an energy source must be available on demand. And it’s here that fossil fuels have a big leg up. Natural gas or coal can be burned at any time to generate electricity as required. Solar panels produce only when the sun shines. Storing adequate energy for later use—i.e., at night or on cloudy days—has long posed a major obstacle.
Solar production has been growing by more than 20 percent annually over the past five years, and likely would have been greater but for the pandemic.
Not anymore, says Daniel Kammen, the founding director of Cal’s Renewable and Appropriate Energy Laboratory and a professor in the Energy and Resources Group and the Goldman School of Public Policy. A coordinating lead author of the Intergovernmental Panel on Climate Change since 1999, he shared in the 2007 Nobel Peace Prize.
“I don’t see storage as a major problem at this point,” Kammen says. “It’s not a single breakthrough that makes me think that way, but more that we’re seeing the same trend in price and performance for storage that we saw with photovoltaics. A variety of approaches are coming to market, and they’re scaling really fast. Things that used to take several years to develop now take a year, and that’s almost certain to continue.”
The storage of the future will serve two different sectors, observes Kammen: transportation (think electric vehicles) and everything else (homes, office buildings, factories, etc.).
EVs
From a climate change point of view, an electrified vehicle fleet is desirable because it dovetails nicely with a green electric grid—i.e., one fed by sustainable energy sources. Currently, cars burning gasoline or diesel spew about 3 gigatons of carbon into the atmosphere each year—about 7 percent of total human-created CO² emissions. Just electrifying roughly a third of China’s vehicle fleet could slash carbon emissions by a gigaton a year by 2040. So there’s a lot at stake with electric vehicles, and everything considered, Kammen is pretty sanguine about their progress.
“It’s really been picking up, particularly over the last year,” he says. “It’s probably not a coincidence that gasoline and diesel prices have been spiking at the same time, and I hate to think that the war in Ukraine is part of that, but it probably is.” EVs are now the best-selling cars in California, Kammen continues, “and it’s the same in Norway, and it’ll soon be the same in New York. Prices on EVs are coming down. The trend is strong and accelerating.”
EVs generally store energy in batteries that use lithium, a relatively rare element that charges and discharges rapidly and is lightweight—an essential quality for automobiles, where excess weight is anathema. Lithium battery technology is well advanced, and some EVs can now go 400 miles between charging, alleviating earlier anxieties about limited range.
A central goal of the Biden administration is the construction of 500,000 new EV charging stations. For perspective: There are currently fewer than 150,000 gas stations in the entire United States.
The next challenge to overcome is a paucity of charging stations, a reality that still gives Tesla drivers pause before embarking on a long road trip. But that’s being remedied, Kammen says, thanks in significant part to the 2022 Inflation Reduction Act (see sidebar), which provides generous home and business tax credits for new and used EV purchases and fast-charging EV stations. A central goal of the Biden administration is the construction of 500,000 new EV charging stations distributed across all 50 states and the District of Columbia and Puerto Rico by 2030. For a little perspective on how ambitious that number is, consider: There are currently fewer than 150,000 gas stations in the entire United States.
“Worries over charging station access are real, there’s no denying it,” says Kammen. “But this legislation, coupled with the fact that recharge times are now very fast, will make a huge difference. The one thing that we still have to address, though, is the social justice component,” as not all zip codes will see the same resources. Without policies to ensure otherwise, Santa Monica will likely have charging stations aplenty; South Central Los Angeles not so much.
“We really need to ensure that doesn’t happen,” says Kammen. “First, it’s wrong. Second, to make a real difference, both energy production and transport must progress across a broad scale. That’s an easier case to make when everyone benefits.”
BATTERIES
In addition to transportation, urban infrastructure must transition to sustainable, carbon-free energy as well. That will require combining clean energy with adequate storage to provide “grid reliability”—that is, systems that will keep the juice flowing in all seasons, even when the sun is absent or the wind stops blowing. In short, you need really, really big batteries.
But what kind of batteries? Lithium-ion batteries, already well established, are one option, says Kammen. But the qualities that make them ideal for vehicles—lightweight, fast charging capabilities—aren’t as critical when you’re trying to light a city at night. For stationary power needs, batteries can be industrial scale—heavy, with a large footprint.
Another problem with lithium is its scarcity. The United States currently controls less than 4 percent of global reserves. For that reason alone, researchers are looking for alternatives: batteries that employ cheaper and more readily available elements.
One of the most promising approaches, according to several sources, is iron-air batteries. And one of the leaders in the technology is Form Energy, a company headquartered in Massachusetts with satellite facilities in Berkeley.
Zac Judkins ’06 is the company’s vice president of engineering. He stresses that Form was obsessed with finding a way to address the problem of multiday storage, not enamored of a particular technology.
Judkins and colleagues evaluated a wide array of candidate chemistries before settling on iron-air batteries, which work by rusting and unrusting thousands of iron pellets with every cycle.
“When we started up in 2017, we saw that the world was rapidly moving to renewables—mainly solar and wind—and setting increasingly ambitious grid reliability and decarbonization goals.” Without effective storage, however, progress was going to hit a brick wall, Judkins says.
Analyzing the market, Form’s engineers arrived at a target. They needed to build a battery that could continuously discharge for 100 hours at a total cost of $20 per kilowatt-hour and had a round-trip efficiency (the amount of energy stored in a battery that can later be used) of 50 percent.
Those parameters, Judkins says, would allow for very high adoption of renewables with no sacrifice to grid reliability and minimal increase in cost to consumers. “That was the benchmark we had to hit.”
Judkins and colleagues evaluated a wide array of candidate chemistries before settling on iron-air batteries, which work by rusting and unrusting thousands of iron pellets with every cycle. Says Judkins, “We didn’t invent the iron-air battery. It was developed by Westinghouse and NASA in the late ’60s and ’70s. They’re not good for cars—they’re not light, and they don’t discharge rapidly. But there are advantages. For one thing, iron is abundant. It’s cheap. We don’t have to worry about supply constraints.”
What you also get with iron, says Judkins, is low cost and high energy density—i.e., the amount of juice you can put into the battery. The tradeoff is lower power density—how fast you can pull the energy out relative to volume.
“It’s roughly 10 times lower on power density than lithium-ion, but for our needs it’s fine,” says Judkins. “This is storage for large-scale, grid-tied projects.” Take the example of a large photovoltaic array like those on California’s Carrizo Plain. One array there has a 250-megawatt capacity, enough for about 100,000 homes, but only when the sun is shining. At night, during storms, there’s no electricity. But, says Judkins, with the addition of a Form plant with a footprint of 100 acres or so, you could store enough energy to keep the electricity flowing for a four-day period.
The company is now transitioning from proof of concept to full production. Ironically, the first commercial rust/unrust battery systems will likely come out of the Rust Belt. “We’re building a factory in West Virginia on a 55-acre site—a former steel plant—that will have approximately 800,000 square feet of production space and employ 750 people at full operation.” Green jobs. Once the plant is fully on its feet, Judkins says, it will produce 50 gigawatt-hours of storage capacity every year.
MICROGRID
In sub-Saharan Africa alone, 600 million people live without electricity. Providing them carbon-free power will require microgrids.
Large, centralized utility grids are naturally the focus for decarbonizing developed countries—but they don’t really apply to parts of the world where access to electricity is still rare. In sub-Saharan Africa alone, 600 million people live without electricity, which doesn’t mean they don’t want it. Providing carbon-free power to these communities will require microgrids: small systems that serve neighborhoods, hamlets, or even multiple villages. But while the microgrid concept has been kicking around for years, its full realization has been elusive—until recently.
“What we’re seeing is a meshing of enabling technologies,” says Duncan Callaway, an associate professor of Energy and Resources at Berkeley and a faculty scientist at Lawrence Berkeley National Laboratory.
For starters, he points to cheap solar. “With the profound price drop in panels, it’s a truly affordable resource that’s ideally suited for mid-latitude countries,” which experience less seasonality. “In general, you can serve electric demand with solar better in those latitudes than in countries [closer to either pole], where there’s just less sunlight.”
Another driver is cheaper, better storage options, Callaway says. For microgrid-scale, lithium-ion batteries work well. And these, too, have grown more affordable. “The explosive growth in electric vehicles really pushed things along,” Callaway says. “Ten years ago, it cost $1,000 for one kilowatt-hour of storage. Now it costs less than $100.”
Finally, says Callaway, “smart grid” technologies have been developed that make microgrids, once notoriously balky, highly efficient.
“We now have ‘big bucket’ control systems that allow for the smooth coordination of energy production, storage, and demand,” Callaway says. “That makes these small grids both low-cost and really reliable. The goal is to make systems that are truly modular, so you can plug various components into larger systems. That will allow easy customization and scaling.”
More than 150 microgrids already are deployed in the United States, powering everything from individual buildings in large cities to small, remote villages in Alaska.
As far as widespread adoption goes, Callaway doesn’t foresee many technical difficulties. It’s social and political roadblocks that need to be overcome. “The great thing about microgrids is that they work well in remote, underserved areas and they can be managed locally. But in less developed countries, there are often corrupt governments that want their cut from any project. And if that’s the case, you’d have an inherent bias toward centralized grids with baseline power plants.”
It’s a challenge that must be met, says Callaway. “Somehow, some way, small grid technology must be put on a level playing field with the old system, the large, centralized grid—or it’s unlikely to make it, even where it’s clearly the superior choice.”
FUSION
Microgrid or macrogrid, we’ll need a lot of clean, sustainable energy flowing through the wires if we’re going to simultaneously sustain an advanced civilization and cool the planet. Kammen is convinced it will largely come from fusion. But by that he means fusion in all its forms, including, as noted, the sun: that massive reactor in the sky that continually fuses hydrogen into heavier elements, releasing 3.8 x 10²6 joules of energy every second.
But there’s also that will-o’-the-wisp that’s been tantalizing futurists and physicists for decades: terrestrial fusion reactors. These would use hydrogen—the most common element in the universe—as feedstock to generate gigawatt-hours of cheap energy, producing harmless, inert helium as the primary by-product. (Radioactive tritium would also be generated, but it has a short half-life and it’s consumed by the reactor in a closed-loop process.) Fusion technology remains the Holy Grail of clean, Earth-friendly energy production, but it’s also the butt of waggish comments. The most common is that it looks promising, but it’s 20 years away. And it’s been 20 years away for 60 years.
But after a breakthrough on December 5, 2022, at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF), it now seems highly possible that a commercial fusion reactor actually could be available in, uh, well, 20 years. Maybe sooner.
Most fusion efforts to date have involved tokamak reactors—toroidal vacuum chambers that corral hydrogen atoms via magnetic coils, subjecting them to heat and pressure until they become plasma, a superheated (as in 150 million degrees Celsius) gas that allows the hydrogen to fuse. This releases energy that transfers as heat to the chamber walls, where it is harvested to produce steam to drive turbines for electricity production.
For the first time on this planet—other than during a thermonuclear explosion—a fusion reaction was created that produced more energy than was required to initiate the process.
Tokamaks have been able to coax hydrogen to fuse for brief periods—indeed, progress has been steady, if plodding, since the first machine was built 60 years ago. But to date, they haven’t been able to achieve “ignition”—that point at which sustained fusion occurs, and more energy is produced by the device than it consumes.
NIF took a different approach. Researchers there fabricated a minute pellet from frozen deuterium and tritium (both hydrogen isotopes). They then placed the pellet in a small gold capsule known as a hohlraum, which in turn was situated on an arm in a chamber bristling with 192 lasers. The scientists then fired the lasers simultaneously at the hohlraum, causing the inner capsule to compress. The result: temperatures and pressures exerted on the deuterium/tritium admixture were extreme enough to produce ignition. For the first time on this planet—other than during a thermonuclear explosion—a fusion reaction was created that produced more energy than was required to initiate the process.
True, the sustained yield was modest. The reaction lasted less than a billionth of a second and released 3.15 megajoules of energy, or slightly less than one kilowatt-hour. Not very much, in other words; the average American household uses about 900 times that every month. Still, it was 50 percent more energy than was expended by the laser bursts. Progress! But here’s another catch: While the actual laser beams represented only around two megajoules of energy, it took about 300 megajoules to power up and operate the mechanisms that fired the beams.
So, there’s still a lot to be done before we’re microwaving our frozen burritos with fusion power. Nevertheless, Kammen, ever the optimist, is fairly sure we will be soon.
“Given the trends, I think I’m pretty safe in predicting that we’ll derive about 70 percent of our power from fusion by 2070,” Kammen says. “Half of that will be from the sun and half from fusion power plants.”
And while NIF’s laser-blasted pellet approach points to future success, don’t rule out tokamaks. Kammen says he’s “expecting some exciting announcements about tokamak reactors pretty soon.” You heard it here first.
Solar fusion, too, will follow multiple avenues toward fuller implementation.
“It’s not just rooftop panels in cities and solar farms out on the landscape,” he says. “There’ll also be marine solar—large arrays out in the ocean.”
Also: orbital solar. Live trials are now underway at Caltech and the Jet Propulsion Laboratory, says Kammen, to establish large, autonomously assembled (i.e., no live astronauts required) solar arrays in space. The energy would be beamed down as microwaves to terrestrial collectors, where it would be converted to electricity. That may raise the specter of a loose-cannon death ray immolating cities from orbit if something goes awry—but not to worry, says Kammen. “The watt-per-square-meter dose is pretty low, so there’s no danger of anyone getting fried if they’re hit by it.”
He also thinks the fusion technology now under development for terrestrial reactors will have applications for space travel. “There’s a dual angle on fusion that’s really catapulting the technology,” Kammen says. “For better or worse, it’s imperative that we colonize the solar system so our fate as a species isn’t completely tied to one planet. Fusion propulsion will be an excellent means for getting us to the moon and Mars and beyond, and fusion—solar, reactor, or both—will also serve as a base-load power source when we get there.”
FISSION
Fission generates a lot of energy from a small footprint. Diablo Canyon, California’s sole nuclear plant, produces almost 10 percent of the total electricity consumed in the state, and it does it within a confine of 600 acres.
With all the fuss over fusion, the other “nuclear” power source, fission, seems to have faded into the background. That’s illusory. Fission is still quite hot, so to speak, with increasing numbers of erstwhile foes in the environmental community now embracing it—or, at least, tacitly supporting it. The reasons are clear. First, fission can generate a great amount of energy on a small footprint. Diablo Canyon, California’s sole operating commercial fission plant, produces almost 10 percent of the electricity consumed in the state and does it within a confine of 600 acres. And from a climate change perspective, nukes are peerless: they emit zero CO².
Of course, people remain worried about other kinds of emissions, such as intense radioactivity from long-lived waste isotopes. And older generation plants—that is, most of the ones operating today—are susceptible to core damage to varying degrees, with catastrophic results à la Chernobyl and Fukushima.
Those concerns are entrenched, especially in the United States, where environmental issues, regulatory red tape, and simple cost often conspire to scotch large infrastructure projects in the proposal phase.
“We’re pretty bad at megaprojects in this country,” says Rachel Slaybaugh, formerly an associate professor in nuclear engineering at Berkeley and now a partner at venture capital firm DCVC. “For one thing, it’s incredibly easy for them to go over budget. Just look at the new Bay Bridge, which ran triple the original estimates.”
That problem is compounded for nuclear plants, given heightened safety concerns and the regulations and litigation they engender. But there has been an upside to the impediments imposed on traditional nuclear power, Slaybaugh says: Out of necessity, more efficient—and perhaps more socially acceptable—technology has been developed.
The newer reactors are smaller—some much smaller—than the behemoths of yore, and pilot projects are underway.
“A good many of these designs originated from basic concepts developed in the 1950s or 1960s, but their refinement and commercial deployment is being driven in large part by our inability to construct large projects,” Slaybaugh says.
Different reactors have been designed for different situations, Slaybaugh observes, employing various fuels, coolants, and configurations. Some “breeder” reactors could even burn their own byproducts, greatly reducing radioactive waste.
“What’s the priority?” Slaybaugh asks rhetorically. “Economics? Providing high-temperature heat, or balancing renewables on the grid? Minimizing nuclear waste? A combination of different goals? These new designs can be standardized or customized and scaled for the site and requirements, and all involve considerable engineering to ensure safety.”
Some of the reactors will be large enough to power a city, or several cities. “And others will be teeny,” Slaybaugh says. “Those will be perfect for remote military bases or research facilities, say Antarctica or the Arctic. You’d eliminate several major problems with one of these very small reactors. Think of the logistical difficulties involved in getting diesel fuel to an arctic base, not to mention the heavy pollution it produces and, of course, the CO² that’s emitted.”
Fission technology also has some profound advantages over renewables, she says. “There are real limits to how many solar farms and wind turbines we should or even can build,” she observes. “A lot of materials are required for their production, and a lot of mining is needed to get the necessary elements. And these facilities tend to have very large footprints. I’m actually worried that we’re going to see a strong solar and wind backlash as people really start to understand all the impacts.”
Every energy source has strengths and weaknesses, continues Slaybaugh, “and we need to have sophisticated conversations on what they are and where each can best apply. Ultimately, my view of fission is that it’s a necessary tool that we must use in conjunction with other available tools to get the job done as well and as quickly as possible. No single solution is going to work for all scenarios.”
CARBON REMOVAL
At this point, we know what we must do to turn things around. Even better, we have the technologies and techniques to do it. But we need to deploy them.
Reducing carbon emissions is not the complete solution to global warming, say scientists. To really get a handle on the problem, we’ll also need to remove existing CO² from the atmosphere and sequester it permanently in the ground. One option, direct air capture (DAC), is the basis for a small but growing industry: Currently, there are about 20 DAC pilot plants operating, in total capturing and sequestering around .01 megaton of atmospheric CO² annually. According to the International Energy Agency, that storage could grow to 60 megatons a year by 2030, assuming large-scale demonstration plants proceed apace, current techniques are refined, and costs drop as the technology scales.
But those are a lot of assumptions for minimal benefit. Granted, a 60-megaton mass of anything is impressive. But from a climate-change perspective, 60 Mt is negligible, given energy-related carbon emissions hit an all-time high of over 36.8 billion tons in 2022. Many researchers think there are better options, and we don’t have to do anything to develop them because they already exist. They point to natural carbon sinks: forests, wetlands, grasslands, and, most significantly, the oceans. These natural systems are part of the Earth’s carbon cycle, which absorbs and releases about 100 gigatons of carbon a year. A planetary mechanism of that scale might seem more than adequate to handle carbon emissions, and it would, if atmospheric CO² only originated from natural emission points such as volcanoes and hydrothermal vents. As noted recently by MIT professor of geophysics Daniel Rothman, natural sources contribute ten times more carbon to the atmosphere than human activities, but it’s the anthropogenic carbon that is pushing the cycle over the edge. The planet can’t process the extra atmospheric carbon back into a stable earthbound state fast enough.
This deficit is exacerbated by the fact that we’re degrading our carbon sinks even as we’re pumping more CO2 into the sky.
“The ecological services carbon sinks provide are really priceless,” says John Harte, a professor of the Graduate School in Berkeley’s Energy and Resources Group. Harte, who conducted pioneering work on the “feedback” effect a warming climate exerts on natural carbon cycles in high-altitude meadows, observes that carbon sinks were poorly understood 35 years ago.
“But we now know they absorb 18 billion tons of CO2 a year. Realistically, we should be putting more of the money we’re devoting to the development of carbon sequestration technology into enhancing natural carbon sinks. At the very least, we need to stop their degradation.”
Harte’s work in the Colorado Rockies entailed artificially heating plots of land and tracking changes in vegetation types and carbon sequestration rates. In plots that weren’t heated and experienced climate change in real time, he found that wildflowers dominated, cycling large volumes of carbon into the soil during the short alpine growing season; when the plants died back each fall, the rate of carbon storage dropped off dramatically. But as Harte warmed specific plots over a period of years, woody shrubs replaced the flowering annual plants earlier than on nonheated land. These slower-growing plants sequestered carbon at a much slower rate than the wildflowers.
“The ‘money,’ the carbon, in the bank account shrinks,” says Harte. But after about 100 years, you begin to see dividends. “The carbon coming into the soil from woody plants is stored longer, so you eventually still have carbon in the soil.”
The goods news: This suggests natural sinks could be managed for optimal storage. But if emissions remain high, they’ll strain and ultimately overwhelm the sequestration capacity of the sinks, negating their value.
“If climate change continues, if we don’t cut back on emissions,” says Harte, “there’ll be no way to buffer the effects.”
And really, that’s the crux of the whole issue. At this point in the climate change crisis, we know what we must do to turn things around. Even better, we have the technologies and techniques to do it. But we need to deploy them. That means everything: solar in all its forms, from rooftop panels to orbital microwave arrays; wind turbine farms, both on land and at sea; fusion reactors; fission reactors; microgrids; massively distributed storage systems. And we must enhance, not debase, the natural systems that sequester carbon. We need to plant many more trees and manage working forests more sustainably, calculating carbon storage as a product equal to or exceeding board feet of lumber. And we need to protect the greatest carbon sink of them all: the ocean.
“I’m terribly worried about the trend toward seabed mining,” says Kammen. “It’s the least regulated of all the new frontiers, some very large companies are pushing it, and it’d be absolutely devastating. If we don’t stop activities like that and if we don’t use all the sustainable energy options that are available, we are risking extinction.”
That may not be a very optimistic note to end on, but then, optimism only gets us so far, doesn’t it? What we need now is grit and determination.

Access to reliable, affordable and clean energy is increasingly recognized as the "golden thread" tying together and enabling many other Sustainable Development Goals (SDGs). Despite progress over the last decade in making solutions to energy poverty more accessible to the more than 800 million people currently without electricity (and the many more with intermittent or unaffordable energy) many gaps remain. In particular, the COVID-19 crisis has disrupted supply and demand for energy, both of which are necessary to meet SDG 7.
At the same time, transitioning to more renewable energy-based electricity systems requiring battery storage, whether in emerging markets or developed ones, will require massive amounts of mineral resources with significant human and environmental footprints. A paper published by USAID in late 2021underscores the urgency of addressing mining in the context of the green energy transition:
Recent global studies predict demand increases of up to ten times current production levels for minerals like cobalt, graphite, and lithium. No matter the mix of alternate energy sources the world turns to, the mining sector will be a key player in the years ahead.
To meet the ambitious goal of universal modern energy by 2030 — while grappling with the consequences of critical minerals demand growth — harmonized policies, coordinated investment and innovative research are urgently needed. Equally or even more important, however, are the understudied and undersupported partnerships that can catalyze and scale these efforts to make SDG7 both a lifeline and a means of economic empowerment and equity.
The Congo Power alliance represents one such innovative coalition approach. Initially launched by Google's Supplier Responsibility team in 2017 to reinforce responsible minerals trade and expand economic opportunity through clean energy, the initiative supports communities committed to the responsible sourcing of minerals that are ubiquitous in electronics and historically tied to conflict and human rights abuses. This mineral trade focuses on tungsten, tin, tantalum, gold and cobalt, making this issue particularly critical in the African Great Lakes Region, where much of the world’s supply of these minerals’ stock lies underground.

As part of its overarching sustainability strategy, Google committed to maximizing our use of finite resources, which includes supporting in-region programs that reinforce responsible supply chains, and increasing the use of recycled materials. These program commitments are also part of meeting the expectations of Section 1502 of the Dodd-Frank Act, which mandate that all publicly traded companies complete due diligence on their supply chains, and report on those measures.
In line with these commitments, the Congo Power team has invested in 14 community projects since 2017 and has brought a broad group of stakeholders along. On a Public-Private Alliance for Responsible Minerals Trade (PPA) delegation with the U.S. State Department in late 2019, for example, Google, Nokia, Intel, Apple, Global Advanced Metals, USAID, U.S. Department of State, GiZ, the Responsible Business Alliance and RESOLVE visited the Idjwi Island minigrid and spent time with the Panzi Foundation’s Denis Mukwege discussing the intersection of human rights and responsible sourcing in the region.
As a result of that trip, the Congo Power team focused on building a deeper relationship with the Panzi Foundation and put community health clinics at the center of addressing power, gender, energy equity along with reinforcing responsible supply chains. The team also continues to expand collaborations with conservation areas such as Garamba National Park, which is deploying clean power systems to support local economic activities (both mining and non-mining) in ways that reduce threats to the park's conservation and biodiversity goals.

The program’s launch highlighted the importance of deep relationships between development partners, consumer brands and NGOs with deep in-country operating expertise, such as GivePower and Resolve. This multi-sector approach is critical for drawing in further "downstream" conglomerates whose customers increasingly demand end products made with responsibly sourced materials.
This strategy has successfully brought on some of the world’s largest manufacturers to the alliance’s commitment to responsible sourcing. Intel has funded two additional phases, and other partners are in the process of making funding commitments. The alliance collaborates with platforms such as Cobalt for Development (BMW, Samsung, BASF, GIZ, Volkswagen, Good Shepherd International Foundation and others) and the Fair Cobalt Alliance(Tesla, Fairfone, The Impact Facility and others) to reinforce mutual objectives in responsible sourcing, and support organizations that are working on the ground.
Beyond public and private partners, academia plays an important role within this consortium. Through a collaboration with the Renewable and Appropriate Energy Lab (RAEL) at the University of California, Berkeley, the Congo Power initiative explores how innovative energy solutions can improve livelihoods and resilience across communities in East and Central Africa. Previously funded research has explored the intersection between energy poverty and conflict, the evolution of real-time monitoring of decentralized energy systems, operating models for mini-grids in urban informal settlements, the impact of solar-home-systems on energy, gender and social justice, and frameworks for understanding community participation’s role in mini-grid projects.
This is just the beginning, however. Many questions remain for the RAEL/Congo Power collaboration to uncover in improving the delivery of sustainable and appropriate energy solutions across the various supply chains that constitute the lifeblood of vulnerable communities around the world.
Chief among the initiative’s research ambitions is developing a deeper sense of how to make $1 of investment in renewable energy "go further." Benchmark impact metrics for innovative energy projects are lacking in the empirical literature, particularly for mini-grid technologies, increasingly recognized as the least-cost way to electrify hundreds of millions of those without power. Developing and documenting enabling partnerships also offers a key resource for nations, businesses, multinational aid / development organizations and civil society to interrogate potential solutions and scale up winning concepts that can help meet goals set in the Paris Climate Agreements and other SDGs.
Fundamentally, such a private-public-academic partnership boils down to exploring what kinds of impact — described both quantitatively and qualitatively — different energy delivery models can achieve across institutional and geographical scales. And beyond the evaluation of impact: Which narratives can most effectively communicate these insights into actionable support for promising solutions and their developers?
Guided by such academic research questions, these partnerships are able to fund implementation partners as well. Nuru, Equatorial Power and OffGridBox are three such partners in East and Central Africa, whose operations are providing critical insights into key techno-economic and operational challenges to scaling energy access.
These organizations have a wide and diverse footprint. Nuru builds and operates mini-grids across remote, rural, and urban areas of the Democratic Republic of the Congo (DRC). Their principal installation is one of the largest mini-grids in Africa, supplying more than 1,800 customers through a 1.3 megawatt solar-hybrid installation in peri-urban neighborhoods in Goma, DRC. Congo Power supported Equatorial Power’s very first installation mini-grid, a 20 kilowatt-peak (kWp) installation on Idjwi Island on Lake Kivu (separating the DRC and Rwanda) supplying over 300 connections, including several small-to-medium enterprises. OffGridBox has deployed one of its 3.4 kWp containerized power and water installations in Walikale (a mining center in eastern DRC), with more than 80 identical such deployments around the world.

To gain deep yet broad insights into the challenge of strengthening the "golden thread," RAEL researchers within the Congo Power alliance aim to be both methodical yet practical in developing research themes from these initial project foci — particularly important given the challenges of doing in-person research through a pandemic.
One theme that consistently emerges through and across such projects is the importance of "productive" uses of electricity — most simply defined as the ability of electricity users to generate additional income on the basis of improved energy access. When, where and how are informal artisans, entrepreneurs and laborers able to convert renewable electricity into improved economic outcomes for themselves, their homesteads and their communities? These questions have proven particularly challenging to answer, despite over two decades of scholarship describing productive uses of electricity as a cornerstone underpinning the financial sustainability, and thus scalability, of energy access solutions with high upfront investment costs and low margins.
RAEL researchers have brought novel evaluation approaches to tackle this problem, including live-monitoring of electricity consumption of productive use pilots across the region, geospatial and remote sensing techniques leveraging satellite imagery and machine learning, as well as piloting new power quality and reliability measurement methodologies for evaluating the state of electricity for health services, including cold storage, through collaborations with infrastructure-monitoring startup nLine.
Many important questions beyond how to catalyze income generating uses of electricity remain, however. Does street lighting reduce crime in remote villages or rapidly urbanizing environments? Can decentralized energy solutions bridge the gaps in Africa’s vaccine cold chains? How can project funders best collaborate with private sector implementers, NGOs, and policymakers to optimize the impacts of a given energy project, targeting outcomes as disparate as supply chain traceability, productive end uses, conservation or women’s empowerment?

Photo by Esther NsapuThese and many other research questions will guide RAEL researchers as the Congo Power initiative continues to gain momentum and partners. A much wider consortium of partners, however, is still needed to confront the magnitude of the challenges ahead, and data-driven research is critical to harness the disparate perspectives, resources and objectives such a big tent approach entails.
For corporate sustainability professionals, joining coalitions such as Congo Power is one way to connect many distinct pieces of the challenges that lie ahead: confronting climate change by supporting cleaner energy production in communities at the very start of their supply chains, tackling the human rights implications of exponential demand growth for minerals required for electronics infrastructure including renewable energy equipment and battery storage technologies, and ensuring the equitable distribution of potential benefits from the global energy transition are distributed equitably. No one company or organization can move the needle on their own, but it is increasingly clear that shareholders, consumers, employees and regulators are placing greater responsibility on global brands to step up to the challenge.
Partnerships such as Congo Power provide a clear pathway for private-public partnerships to explore and support cutting-edge projects, technologies and infrastructures, guided by the most recent empirical evidence of impact. With rigorous, intersectional and actionable research guiding such a powerful coalition of committed partners, a truly just energy transition is possible.

It is abundantly clear that adequate, reliable and clean energy services are vital for the achievement of many of the Sustainable Development Goals (SDGs). In essence, energy access has come to represent one of the intractable challenges in development, and therefore emblematic of the call for poverty eradication, and economic and social transformation. This focus issue on "Energy Access for Sustainable Development" is initiated to draw broadly from the ideas and emerging experiences with energy activities and solutions that sought to enhance sustainable development through expansion of energy access. The focus issue includes several contributions from authors on some of the knowledge gaps this field, including: (i) the role of off-grid and mini-grid energy systems to meet multiple SDGs; (ii) the impacts of the evolving suite of off-grid and distributed energy services on inequalities across gender, and on minority and disadvantaged communities; (iii) the opportunities that the evolving technology base (both of energy services and information systems) plays in expanding the role of off-grid and mini-grid energy systems; (iv) energy options for cooking; (v) new insights into energy planning as well as the political economy, institutional and decision challenges across the energy system. Drawing from papers in this focus issue and other literature, this paper provides a sketch of the key issues in energy access.
The Intergovernmental Panel on Climate Change, which shared the 2007 Nobel Peace Prize, issued a critical report in October 2018 on the vital need to hold anthropogenic global warming under 1.5 degrees Celsius. Humans have already warmed the planet 1 degree C.
An about-face on pollution and planetary degradation is needed to achieve this remarkable goal, with actions at the individual, community, national, and global scales. Thankfully, the pace of innovation and improvement of clean-energy technologies has been dramatic, but we are still far from on track to meet this climate imperative.
In this talk, Daniel M. Kammen will examine the pace of scientific change, the problem of sustained innovation and deployment, and the tremendous array of benefits that could be realized by making climate protection the priority it must become. Most remarkable, perhaps, is the range of benefits—in social equity, ethnic and gender inclusivity, cultural diversity, and poverty alleviation—that can be realized through an energy plan Earth can live with.

The Beautiful Rivers—And the DammedAdvances in solar and wind power mean that hydropower is no longer the only renewable game in town—and that’s good news for the world’s rivers.BY JEFF OPPERMAN, CHRIS WEBER, DANIEL KAMMEN

In October, the Intergovernmental Panel on Climate Change released a report outlining strategies the world can pursue to keep global warming below 1.5 degrees Celsius and maintain healthy economies and ecosystems. But unless we are smart about how we implement that blueprint, it could cause irreparable damage to the world’s great rivers.
The panel’s report urges a rapid transition to low-carbon, renewable sources of electricity. That call to action could trigger expanded investment in hydropower, which is currently the world’s main source for that kind of energy (70 percent as of 2017). But if that development follows the pattern of earlier dam-building, it could accelerate an alarming loss of rivers and their resources, including of the fish that feed hundreds of millions of people.
The case of the Mekong River puts the problem into sharp relief. The river is the world’s most productive freshwater fishery—it provides nearly 20 percent of the annual global freshwater fish harvest, the primary source of protein for tens of millions of people in the region. Already, several hydropower dams on the Mekong are under construction or are moving through the planning process. Scientists estimate that those dams, if completed, will cut the river’s annual harvest by half.
With the Mekong Delta’s sand supply cut off, scientists project that it will sink and shrink, with more than half underwater by the end of the century.
The dams are also projected to trap within their reservoirs more than 90 percent of the sand that would otherwise flow into the Mekong Delta, which is home to 17 million people and produces 90 percent of Vietnam’s rice exports. With its sand supply cut off, scientists project that the delta will sink and shrink, with more than half underwater by the end of the century.
It is easy to hear such stories and conclude that the world faces an agonizing dilemma: Must we sacrifice our rivers to save our climate? Even just a few years ago, that trade-off seemed unavoidable. With wind and solar power limited by their expense and variability, global hydropower was projected to nearly double by 2050. Massive dams were under construction or planned for many of the world’s great rivers, including the Yangtze, Mekong, and most tributaries of the Amazon. Some governments used climate and renewable energy objectives to justify these projects, even as scientists quantified their impacts and affected communities and indigenous groups protested.
But we do not need to sacrifice rivers for zero-carbon energy. In the last two years, solar energy has rapidly become more economically viable due to technological improvements and to economies of scale in production and deployment. Whereas solar energy used to cost 20 cents or more per kilowatt-hour, new projects in Chile, Mexico, and Saudi Arabia have come in at one-tenth that cost. Wind energy costs have likewise plummeted. In 2017, a winning bid for a new wind farm in Mexico featured costs of around 2 cents per kWh. That was half the previous year’s lowest bid there. This makes solar and wind the price leaders across much of the world.
Even with falling costs, the variability of wind and solar power remain a challenge. Simply put, in order for these technologies to offer reliable, round-the-clock electricity generation, there needs to be a way to store power when the wind is blowing and the sun is shining and then deploy it when the wind dies down or the sun sets.
Fortunately, the costs for storage technologies are plummeting as well, with the cost of lithium ion batteries, capable of grid-scale storage, dropping by about 90 percent over the past few years. New technologies are emerging as well. For example, a Chilean solar power plant that uses molten salt as storage recently offered to provide24-hour baseload electricity at less than 5 cents per kWh. That is comparable to or cheaper than most hydropower and fossil fuel options. Tesla and Google X, meanwhile, are pursuing “moonshot” solutions for storage technologies.
Also tipping the scales toward wind and solar is that, among large infrastructure projects, hydropower dams have among the worst performance in terms of delays and cost overruns, in part due to the conflict and controversy surrounding them. Whereas some dams take a decade to complete, wind and solar power can be delivered through rapid, smaller-scale, and lower-risk projects that tend to engender far less conflict.
Governments are taking note. Thailand earlier this year signaled that it would delay signing a power purchase agreement for Pak Beng, a 912-megawatt hydropower dam that Laos is planning for the Mekong. In announcing the delay, the country stated that it needed to revisit its energy strategy since other renewable sources, including wind and solar, were becoming increasingly viable. Thailand was slated to buy 90 percent of the dam’s electricity, so its change of plans could spell the end of the project. In Guyana, meanwhile, rising cost estimates and delays for the Amaila Falls hydropower project led the government and financiers to transfer funding intended for the dam toward a 100-megawatt solar project.
The rapidly evolving renewable energy landscape doesn’t mean an end to hydropower, but rather a shift in its role. Hydropower reservoirs are currently the dominant form of energy storage for grids, and although other forms of storage are improving, they will continue to provide critical storage services in the near future. Upgraded older dams and strategically planned new projects, carefully located to minimize environmental and social disruption, can emphasize energy storage to facilitate adding large increments of wind and solar into a grid.
Although it is now possible to build affordable, low-carbon wind and solar systems, they still face constraints, including political and social preferences for large infrastructure projects. Pak Beng may have been paused, but other dam projects on the Mekong and on other key rivers are moving forward.
It would be a great tragedy if the renewable revolution arrived just a few years too late to save the world’s great rivers. Market reforms and new financial mechanisms can accelerate the adoption of more sustainable energy systems, as can innovative science. For example, the Renewable and Appropriate Energy Laboratory at the University of California, Berkeley recently developed and is using an energy planning model for Laos. The lab found that investments in solar panels (backed up by existing hydropower) could meet that nation’s objectives for selling electricity to neighbors—with greater returns and lower risks than the planned dams that threaten the Mekong’s fish harvests and the viability of its delta.
There’s no need to continue accepting tragic trade-offs between healthy rivers and low-cost, reliable, and renewable electricity. The renewable revolution provides an opportunity to have both. Governments, funders, developers, and scientists should seize it.

Good Grids Make Good Neighbors: Peace and Sustainability in the Post Paris World
Location: William J. Perry Conference Room, Encina Hall, 2nd Floor, Stanford University, 616 Serra St, Stanford, CA 94305
3:30 - 5:00 PM, Monday, February 26, 2018
Abstract: Clean energy provides a number of benefits at scales from household to village to city and region. An unrealized and under-appreciated opportunity is to transition conflict regions from external fuel supply chains to local, clean and unpolluting energy. The benefits of this transition include local energy security to shared benefits from sustaining local generation capacity, which we term 'peace through grids'.

Overview:
Energy poverty, is arguably the most pervasive and crippling threat society faces today. Lack of access impacts several billion people, with immediate health, educational, economic, and social damages. Furthermore, how this problem is addressed will result in the largest accelerant of global pollution, or the largest opportunity to pivot away from fossil-fuels onto the needed clean energy path. In a clear example of the power of systems thinking, energy poverty and climate change together present a dual crisis of energy injustice along gender, ethnic, and socioeconomic grounds, which has been exacerbated if not caused outright by a failure of the wealthy to see how tightly coupled is our collective global fate if addressing climate change fairly and inclusively does not become an immediate, actionable, priority.
While debate exists on the optimal path or paths to wean our economy from fossil fuels, there is no question that technically we have today a sufficient knowledge and technological foundation to launch and to even complete the decarbonisation (IPCC, 2011). Critically needed is an equally powerful social narrative to accelerate the clean energy transition. Laudato Si’ provides a compelling formulation of the injustice that is both greed and pollution, but an ongoing outreach and partnership effort is needed to truly leverage its powerful message.
In this essay we present examples across scales of the evolving knowledge base needed to build universal clean energy access. This leads to a formulation of an action agenda to defeat energy poverty and energy injustice.

310 Barrows Hall, Room 323
---Wednesday---
While geoengineering was once considered to be “taboo” in the forum of climate change policymaking, the increasing desperation engendered by the specter of passing critical temperature thresholds has led to increasing interest in the approach, including by key stakeholders. Even President Obama’s chief science advisor has indicated that geoengineering should “not be taken off the table” as a potential component of climate policymaking. The purpose of this presentation will be to assess the potential benefits of climate geoengineering, as well as potential negative impacts. Moreover, the presentation will discuss governance issues, including pertinent international treaty regimes, the contours of a potential framework for liability for potential negative impacts.
Wil Burns currently serves as the Co-Director of the Forum for Climate Engineering Assessment, a scholarly initiative of the School of International Service at American University. He previously served as Director of the Energy Policy & Climate program at Johns Hopkins University and has taught also at Tulane University’s School of Law, Colby College and Williams College. He holds a Ph.D. in International Law from the University of Wales-Cardiff School of Law.
While the boons of electricity are obvious to anyone who has watched a 49ers game on a 70-inch ultra HDTV or whipped up a frozen margarita in a blender, it also has its downsides—most of them environmental. Coal and natural gas power plants belch planet-warming CO2 into the atmosphere, while nuclear plants produce highly lethal radwaste.
Still, access to electrical power is a basic social-equity issue. About 1.5 billion of the planet’s 7 billion people lack electricity, and their lives are impoverished, physically and culturally, as a result. Further, a deficiency of electricity generates environmental problems of its own. If people lack electricity to cook their food or warm their homes, they’ll substitute wood or charcoal, resulting in deforestation and yes, more carbon spewing into the atmosphere.
But a paper by UC Berkeley researchers Peter Alstone,Dimitry Gershenson and Daniel Kammen indicates that a major change in the way power is produced and consumed is in the offing—one that could electrify the developing world (literally and figuratively) while promising reduced carbon emissions.
The study, published in the journal Nature Climate Change, identifies the present moment as a tipping point, one in which decentralized transmission networks, cheap photovoltaics, sophisticated low-energy appliances, mobile phones and “virtual” financial services are all merging to create a kind of alt-grid that will, as one addicted to clichés might say, shift the energy paradigm.
Here’s what’s happening: Solar panels and batteries have gotten both better and cheaper, to the point that the developing world’s mini-grids (for communities) and micro-grids (villages or individual homes) can afford them. Such systems are easier and cheaper to set up than legacy systems dependent on big, centralized power plants and tower-supported transmission lines festooned around the countryside. Ultra-efficient appliances—everything from TVs to refrigerators—also are now widely available, as is LED lighting (which uses minimal power).
“What’s making this new system possible is the merging of information and energy technologies, of aggressive innovation in both the power production and smart phone worlds,” says Kammen, a professor at the Goldman School of Public Policy and the director of UC’s Renewable and Appropriate Energy Laboratory.
Kenya was once an energy black hole. Today Masaai moran (warriors) herd their livestock while simultaneously checking cattle prices in Mombasa on their cell phones, which they holster in beaded pouches worn around their necks.
The abrupt and massive spread of cell phone technology has encouraged virtual banking systems that allow small-scale energy producers and their customers to do business from anywhere, and on a pro-rata basis. Customers are able to buy power in exceedingly small increments—say, enough to recharge their cell phones and power an LED light or two, or a tiny refrigerator and a high-efficiency hot plate. That’s a big deal in the developing world, where even a few such amenities make a gigantic difference in the quality of life—and where cash always is in short supply. It allows customers in rural Africa and Asia to analogously do with energy what they do when they visit a village store: buy a single stick of gum or a matchbook.
Indeed, Kammen says, trusted e-banking systems are essential for the support of the mini-grid network, and he notes that the developing world has led in creating apps for such services.
He cites Kenya as an especially shining example. Fifteen years ago, the country was a communications black hole. Hard-line telephony was the rule, and spotty at best. Outside Nairobi and Mombasa, people made do with CB radios or word of mouth. Then mobile technology arrived, and within a few years everyone was connected. Today, when visiting the country’s wildlife reserves, you’ll see Masaai moran (warriors) herding their livestock while simultaneously checking cattle prices in Mombasa on their cell phones, which they holster in beaded pouches worn around their necks.
“In the 1990s I helped start up Mpala Research Center in Laikipia [in northern Kenya],” recalls Kammen. “We had to wait for a satellite to pass overhead so we could make our 35-second phone calls. Now researchers are receiving streaming data on individual lions and African wild dogs that they’re tracking.”
In 2007, a proprietary mobile system known as M-Pesa was launched in Kenya. Originally promoted as an easy way to post payments for microloans, it was soon used by working urbanites as a means of sending money to relatives back on the rural shamba. M-Pesa is now Kenya’s preeminent banking system. As of late 2013, 19 million of the country’s 44 million people were signed up, with 25 percent of the national economy flowing through M-Pesa’s virtual conduits. In terms of energy development, that means small-scale power providers can receive payment for specific services from customers seamlessly, bypassing everything from poor infrastructure (people don’t have to walk miles over cattle trails to pay their bills) to government and corporate corruption.
“And we’re seeing other IT applications all around the developing world,” Kammen says. “In Bangladesh, for example, phones are being used to test battery [arrays]. Keeping battery systems fully functional is critical for mini-grids, and it’s a big problem in Bangladesh, where a third of the country floods each year. Mini-grids don’t have maintenance teams regularly checking the systems, but you can upload data on cell phones when there’s a specific problem, and the provider can deal with it.”
“We’re moving from an era that has remained under-innovated for decades—the system where you pay a big utility for your energy—to decentralized systems…. It’s essentially the democratization of energy.”
Decentralized electrification also reduces the causes of deforestation. When people have electricity, the rate of charcoal and wood burning typically decreases dramatically, Kammen observes.
And decentralized energy isn’t just an accelerating trend in the developing world. In America, solar panels are sprouting on suburban homes like chanterelle mushrooms in Mendocino after a winter rain; cell phones are ubiquitous. The United States, in short, is experiencing its own decentralized energy revolution.
“I have solar panels on my roof, and I can use my phone to track how much power each one is producing,” Kammen says. “I can determine which ones are dirty and may need a cleaning to improve performance. I can see how green my energy consumption is at any moment.”
That points to a shift in power (political, not electrical) from the energy producer to the consumer. In fact, Kammen contends that the “Big Grid” of the existing utilities must adapt, melding with the growing mini- and micro-grids, to thrive.
“We’re moving from an era that has remained under-innovated for decades—the system where you pay a big utility for your energy—to decentralized systems that have a lot of networked components and consumer input, all driven by powerful IT,” Kammen says. “It’s essentially the democratization of energy.”
But to really accelerate the trend, Kammen says, a big dog must emerge from the pack of alt-energy advocates.
“We’re working with a number of start-ups that are wrestling with the best way to put this all together,” Kammen says. “Nobody has hit on the right approach yet, but I anticipate somebody will do a Facebook kind of breakout sooner or later, come up with an off-grid version of Tesla. Our paper has been getting a lot of response in the week since its publication, in part because it demonstrates just how negative the impacts of poor energy access are. We show how it stymies educational opportunities and exacerbates gender inequality. It accelerates deforestation and can increase carbon emissions. But we also identify a goal: providing electricity to the 1.5 billion people who don’t have it by 2030. And with the systems we discuss, we think that’s achievable.”
In 2007, a proprietary mobile system known as M-Pesa was launched in Kenya. Originally promoted as an easy way to post payments for microloans, it was soon used by working urbanites as a means of sending money to relatives back on the rural shamba. M-Pesa is now Kenya’s preeminent banking system. As of late 2013, 19 million of the country’s 44 million people were signed up, with 25 percent of the national economy flowing through M-Pesa’s virtual conduits. In terms of energy development, that means small-scale power providers can receive payment for specific services from customers seamlessly, bypassing everything from poor infrastructure (people don’t have to walk miles over cattle trails to pay their bills) to government and corporate corruption.
“And we’re seeing other IT applications all around the developing world,” Kammen says. “In Bangladesh, for example, phones are being used to test battery [arrays]. Keeping battery systems fully functional is critical for mini-grids, and it’s a big problem in Bangladesh, where a third of the country floods each year. Mini-grids don’t have maintenance teams regularly checking the systems, but you can upload data on cell phones when there’s a specific problem, and the provider can deal with it.”
