Accelerating the rate of renewable energy deployment in Small Island Developing States is critical to reduce dependence on expensive fossil fuel imports and meet emissions reductions goals. Though many islands have now introduced policy measures to encourage RE development, the existing literature focuses on qualitative recommendations and has not sought to quantitatively evaluate and compare the impacts of policy interventions in the Caribbean. After compiling the first systematic database of RE policies implemented in 31 Caribbean islands from 2000 to 2018, we conduct an econometric analysis of the effectiveness of the following five policy interventions in promoting the deployment of RE: investment incentives, tax incentives, feed-in tariffs, net- metering and net-billing programs, and regulatory restructuring to allow market entry by independent power producers. Using a fixed effects model to control for unit heterogeneities between islands, we find evidence that net-metering/net-billing programs are strongly and positively correlated with increases in installed capacity of renewable energy - particularly solar PV. These findings suggest that the RE transition in the Caribbean can be advanced through policies targeting the adoption of small-scale, distributed photovoltaics.
New analysis from University of California, Berkeley researchers finds that China is the only nation on track to triple its renewable capacity by 2030, a key goal for limiting global warming to 1.5 degrees Celsius.
Amid continuing geopolitical tensions, climate change remains a key area of collaboration between the United States and China. Ahead of last November’s United Nations Climate Change Conference (COP28), Presidents Biden and Xi reaffirmed their commitment to work jointly—and together with other countries—to address the climate crisis and limit global warming to 1.5 degrees Celsius.
Central to the agreement, now known as the "Sunnylands Statement,” is a commitment to supporting efforts to triple the global production of renewable energy by 2030. That goal, which is the only quantitative target in the agreement, was previously identified as a key target by the International Energy Agency (IEA) and the International Renewable Energy Agency (IREA) and agreed to by G20 leaders during their September 2023 meeting.
A study published today in Environmental Research Letters by UC Berkeley researchers finds that the global growth rate of renewable and low-carbon energy capacity is insufficient to meet this target. Using historical data from IRENA and the IEA, the authors project that China is by far the closest to triple its capacity by 2030, while the five remaining regions—the U.S., European Union, the African continent, Central and South America, and the rest of the world—will fall short.
“The climate crisis is now an emergency of inaction on a true energy transition,” said co-author Daniel Kammen, the James and Katherine Lau Distinguished Professor of Sustainability in the Energy and Resources Group (ERG), the Goldman School of Public Policy, and the Department of Nuclear Engineering. “While some specific policies and the actions of some nations show that a clean, green energy future can be achieved, we must be more systematic, holistic, and aggressive in our actions.”
China’s renewable energy capacity tripled during the last decade, a historic trend projected to continue through 2030. While developers of renewable energy projects in China may face difficulty securing financing and integrating their projects onto the grid, the country regularly surpasses its conservative targets and is more capable of leveraging other policies to facilitate necessary growth.
By comparison, the U.S. would need to significantly raise its renewable ambitions to achieve this target. The authors point to the 2022 Inflation Reduction Act, which authorized $369 billion in new government spending on clean energy and climate mitigation over the next decade, as one successful policy intervention capable of bringing the U.S. closer to its target. While they estimate that IRA-linked renewable energy projects will increase the domestic renewable energy capacity by a factor of 2 or 3, the U.S. would need to more than quadruple current projections to meet its stated targets.
“It’s heartening to see the exponential deployment of the past decade, and 2023 saw by far the biggest gains yet,” said co-author Ari Ball-Burack, a PhD student in ERG. “Moving forward, the U.S. and China have a responsibility to concretely facilitate renewables deployment worldwide.”
Co-author Xi Xi, a graduate student in ERG, notes that the greatest challenge the U.S. and China face will be facilitating and supporting efforts toward tripling renewable energy capacity elsewhere. Renewable energy deployment and power sector expansion are crucial to Africa’s sustainable development goals, yet so much of the continent’s energy development has been historically under-invested. The IEA estimates that more than $200 billion per year of investment by 2030 is required to achieve key energy goals and facilitate a just and inclusive climate transition. Comparable levels of investment are also needed in Central and South America and across the rest of the world.
“The U.S. and China operate within a global context and must proactively acknowledge and incorporate global perspectives, particularly from the Global South, and actively contribute to climate mitigation efforts worldwide,” she said.
The researchers assert that although the two countries’ joint declaration sets an optimistic framework with which to build lasting international climate cooperation, much work remains to limit warming to 1.5 degrees Celsius. They propose four actionable steps to ensure the Sunnylands tripling commitment is met:
The commitments must transform into delivered funds, with actionable plans to assemble and distribute funds committed to addressing challenges of climate mitigation and adaptation.
Subnational and informal collaborations between the two countries and the rest of the world should accelerate technology and knowledge transfer to provide appropriate, effective, and efficient solutions.
The two countries should prioritize collaboration over competition. A competitive mindset could hinder the development of globalized supply chains, significantly increasing renewables costs.
Fostering an inclusive and collaborative climate discourse internationally is crucial for a speedy, just transition toward the net zero world and can facilitate and accelerate reforms in multilateral institutions to ensure just and viable institutional and financial mechanisms for renewables development in the Global South.
As governments and non-state actors strive to minimize global warming, a primary strategy is the decarbonization of power systems which will require a massive increase in renewable electricity generation. Leading energy agencies forecast a doubling of global hydropower capacity as part of that necessary expansion of renewables. While hydropower provides generally low-carbon generation and can integrate variable renewables, such as wind and solar, into electrical grids, hydropower dams are one of the primary reasons that only one-third of the world’s major rivers remain free-flowing. This loss of free-flowing rivers has contributed to dramatic declines of migratory fish and sediment delivery to agriculturally productive deltas. Further, the reservoirs behind dams have displaced tens of millions of people. Thus, hydropower challenges the world’s efforts to meet climate targets while simultaneously achieving other Sustainable Development Goals. In this paper, we explore strategies to achieve the needed renewable energy expansion while sustaining the diverse social and environmental benefits of rivers. These strategies can be implemented at scales ranging from the individual project (environmental flows, fish passage and other site-level mitigation) to hydropower cascades to river basins and regional electrical power systems. While we review evidence that project-level management and mitigation can reduce environmental and social costs, we posit that the most effective scale for finding balanced solutions occurs at the scale of power systems. We further hypothesize that the pursuit of solutions at the system scale can also provide benefits for investors, developers and governments; evidence of benefits to these actors will be necessary for achieving broad uptake of the approaches described in this paper. We test this hypothesis through cases from Chile and Uganda that demonstrate the potential for system-scale power planning to allow countries to meet low-carbon energy targets with power systems that avoid damming high priority rivers (e.g., those that would cause conflicts with other social and environmental benefits) for a similar system cost as status quo approaches. We also show that, through reduction of risk and potential conflict, strategic planning of hydropower site selection can improve financial performance for investors and developers, with a case study from Colombia.

Before the COVID-19 pandemic hit, renewable energy was growing steadily — but still not fast enough to meet the Paris Agreement’s carbon reduction goals, let alone to make the further strides needed to keep climate change from spiraling out of control.
Now, the virus-induced economic shock is likely to slow the expansion of wind, solar, and other clean power sources, at least temporarily, experts say. But while lockdowns, social distancing requirements, and financial uncertainties have put some new projects on ice, the underlying strengths of renewables remain strong, and analysts expect their economic advantage over volatile fossil fuels will only increase in the long term.
Leaders must seize the opportunity to design economic recovery packages so they accelerate a shift toward wind and solar power, rather than propping up the fossil fuel economy, said Francesco La Camera, director-general of the International Renewable Energy Agency, an intergovernmental body.
“The only thing we have to be afraid of,” he said, “is that governments can be pushed by lobbyists to bail out sectors that belong to the past. And this is the real danger.”
As shutdowns aimed at stemming the viral spread have caused global energy demand to plummet, renewable sources have accounted for an increased share of power generation. That is in part because the low cost of solar and wind power means they are often dispatched to grids before other sources such as coal and nuclear power. The huge drop-off in demand, for both electricity and transportation fuels, has also pushed oil and gas prices to historic lows, and left fossil fuel companies struggling to find storage space for huge gluts of product.
In the short term, however, analysts say that the global economic fallout from the pandemic will almost certainly also be a drag on the growth of renewables. Stay-at-home orders halted production at factories making solar panels and wind turbine parts, and shipping delays have exacerbated supply problems. Construction on some big arrays stopped, and social distancing requirements have forced home solar companies to postpone rooftop installations and sales visits.
“The industry needed installations to be speeding up rather than slowing down at this point” for countries to bring carbon-cutting realities into line with their promises under the Paris Agreement, said Logan Goldie-Scot, head of clean power research at analysis firm BloombergNEF, or BNEF. “Anything that makes that gap bigger is hugely problematic from an emissions perspective.”
BNEF has scaled back its projections for 2020 installations by 12 percent for wind and 8 percent for solar, compared to what it anticipated before the pandemic. Renewables growth has been steady in recent years, and last fall, the International Energy Agency, or IEA, predicted the world’s renewable power supply would grow by 50 percent over the next five years, adding new power generation equivalent to the entire existing electricity capacity of the United States.

“We were expecting a boom year” in 2020, said Heymi Bahar, the IEA’s senior renewables analyst. “So this becomes very bad timing.”
The bigger question, experts say, is what happens as countries reopen. With cash tight, and economic troubles expected to keep energy demand below pre-COVID-19 levels, new wind and solar projects may find financing hard to come by.
Auctions in which companies bid to build such projects have been postponed. Altogether, more than 40 percent of wind and solar capacity that was scheduled to be commissioned from April to the end of this year has been delayed, said Goldie-Scot. “That’s an immediate setback.”
Home solar took a bigger hit than utility-scale projects. Those rooftop sales are likely to continue struggling, as the slowdown forces homeowners and small businesses to restrict spending on big-ticket items like solar arrays, even if, in the long run, they generate substantial savings.
Still, analysts agree the renewable energy sector’s fundamentals are strong. A lot has changed since the last global meltdown, the financial crisis of 2007-08. Technologies have matured and prices dropped, to the point where renewables in most cases provide cheaper energy than fossil fuels. Battery storage, key to making clean power steady and reliable, is improving rapidly.
“Renewable generation sources have become extraordinarily competitive from an economic standpoint,” said Dan Shreve, head of global wind energy research at consulting firm Wood Mackenzie. “It’s a terrific story. Do we expect any of that to change in the near term? No, I don’t think so.”
Indeed, with oil companies in a tailspin, clean energy’s steadiness also increases its appeal to investors, in Shreve’s view. “Folks looking for a safe haven in a very turbulent market may continue to turn to this sector,” he said.
Even the breathtaking drops in oil and gas prices may not be enough to undermine wind and solar. While oil is central to transportation, it doesn’t play a direct role in power generation. And its low price will mean drilling is scaled back. Since natural gas — which does go up against wind and solar in electricity markets — often flows from the ground along with oil, its supply is likely to decline too, bringing its price back up.
“Which means it won’t be competitive with renewables,” said Amy Myers Jaffe, director of the Program on Energy Security and Climate Change at the Council on Foreign Relations.
Indeed, Shreve said nuclear and coal-fired power plants faced far stiffer headwinds than renewables. “That’s been the case for the last five years. It was expected to be the case for the next five years, regardless of the Covid crisis,” he said. Early retirements of such plants, particularly the ones for which finances were already in trouble, could pick up pace, he said.
Another sector likely to take a hit is electric cars. That has less to do with low oil prices than with unemployment slowing sales for all cars, Jaffe said. “If you believe that people were going to have the next car they buy be an electric vehicle, if you delay by two or three years the next time they’re going to buy a new car,” that will slow the transition, she said.
Fewer electric cars means less power demand, which hurts the renewables outlook. But Jaffe said the pandemic could hasten the economy’s electrification in other ways, including a long-term increase in remote working, which would likely shift energy demand away from oil-based transportation needs, and toward residential use, which is more heavily electric.

In the bigger picture, what comes next depends on the virus, the economy, and the path governments decide to chart. With vast amounts of stimulus money likely to be poured into economies around the world, clean power advocates say it’s a historic opportunity to speed the growth of a sector whose fortunes are central to hopes of stemming climate change. La Camera said the renewable energy sector’s big-picture strengths, and its resilience through the crisis so far, make him hopeful.
“My impression is that we are going to have a future that will be more decarbonized than we could have imagined three months ago,” he said. “And in the end, this health and economic crisis will push us to a cleaner path forward.” Risks in the other direction include not just direct government support to oil firms, but also regulatory loosening like the Trump administration’s decision to essentially suspend enforcement of air and water pollution rules, or to relax limits on mercury and other toxic power plant emissions. Such moves save the industry vast sums it would otherwise have to spend reducing pollution, said Daniel Kammen, professor of energy at the University of California, Berkeley.
Even without a push to help fossil fuel companies, COVID-19 could bump climate change down the list of leaders’ priorities.
For now, most governments are still focused on immediate response to the health and jobs crisis. Longer-term measures will come next, and countries including South Korea and New Zealand are already talking about incorporating climate action into recovery plans. The European Union may combine parts of its Green Deal — a plan for transforming nearly every sector of its economy to cut carbon and improve quality of life — with efforts to repair the pandemic’s damage. In the U.S., the fate of any ambitious renewables plan depends largely on whether President Trump is reelected in November.
For the most part, countries’ interest in green stimulus plans aligns with their pre-coronavirus stance on climate action. “We think they are more likely in countries where there was already broad-based support,” such as China and much of Europe, Goldie-Scot said.
What might green recovery efforts entail? Given clean power’s competitiveness, companies don’t really need direct subsidies anymore, experts say. They would benefit from upgrades that make power grids smarter and more flexible, and therefore better able to utilize renewables. Spending to expand electric vehicle charging networks is essential, too, the analysts say.
The U.S. and China both have year-end deadlines when important tax and price incentives for renewables expire.
Access to credit will also be crucial, Bahar said. While it easily competes with fossil fuels on cost, “the renewables industry just doesn’t have as deep pockets,” added Kammen.
Policy changes matter, as well. National, long-term carbon-cutting commitments would provide some certainty in frightening times. In the shorter term, the U.S. and China both have year-end deadlines when important tax and price incentives expire; extending those would help projects delayed by the pandemic, analysts say.
Green stimulus advocates say climate action is well-suited to creating jobs, and if done right can also help remedy the stark economic, social, and racial inequalities the virus has exposed so vividly, particularly in the U.S.
A shift to cleaner energy promises health gains too. Many have taken note of the better air quality lockdowns have brought, and Shreve said that could help people see the benefits of finding lasting ways to reduce fossil fuel use.
“The one bright spot in this crazy crisis is to have been able to walk outside in places that have been notorious for air pollution, and seeing clean skies, and having a dose of what could be,” he said.
Kammen said he is hopeful the pandemic would ultimately speed the move to a cleaner economy.
“Covid gives an opportunity for governments and companies to make that switch more strongly,” said Kammen. “I don’t think this is going to be an easy goodbye, but I would definitely say we’re in the long goodbye to fossil fuels.”
The short-term prospects for wind and solar power look rocky amid the economic upheaval of the coronavirus. But long term, renewables could emerge stronger than ever, especially if governments integrate support for clean energy into COVID-19 economic-recovery programs.
Before the COVID-19 pandemic hit, renewable energy was growing steadily — but still not fast enough to meet the Paris Agreement’s carbon reduction goals, let alone to make the further strides needed to keep climate change from spiraling out of control.
Now, the virus-induced economic shock is likely to slow the expansion of wind, solar, and other clean power sources, at least temporarily, experts say. But while lockdowns, social distancing requirements, and financial uncertainties have put some new projects on ice, the underlying strengths of renewables remain strong, and analysts expect their economic advantage over volatile fossil fuels will only increase in the long term.
Whether the pandemic ultimately puts clean energy on a faster track than before, though, depends to a large extent on the choices political leaders make now, analysts say. Which means 2020 is shaping up to be a pivotal moment for renewables — and the world’s hopes of checking warming.
Leaders must seize the opportunity to design economic recovery packages so they accelerate a shift toward wind and solar power, rather than propping up the fossil fuel economy, said Francesco La Camera, director-general of the International Renewable Energy Agency, an intergovernmental body.
Some 40 percent of wind and solar capacity that was scheduled for the rest of 2020 has been delayed.

In 2015, ASEAN established a goal of increasing renewable energy share in its energy portfolio from approximately 13–23% by 2025. Renewable electricity, especially intermittent and variable sources, presents challenges for grid operators due to the uncertain timing and quantity of electricity supply. Grid flexibility, the electric grid's ability to respond to changing demands and supply, now stands a key resource in responding to these uncertainties while maximizing the cost-effective role of clean energy. We develop and apply a grid flexibility assessment tool to assess ASEAN's current grid flexibility using six quantitative indicators: grid reliability, electricity market access; load profile ramp capacity; quality of forecasting tools; proportion of electricity generation from natural gas; and renewable energy diversity. We find that ASEAN nations cluster into three groups: better; moderately; and the least prepared nations. We develop an analytical ramp rate calculator to quantify expected load ramps for ASEAN in an integrated ASEAN Power Grid scenario. The lack of forecasting systems and limited electricity market access represent key weaknesses and areas where dramatic improvements can become cost-effective means to increase regional grid flexibility. As ASEAN pursues renewable energy targets, regional cooperation remains essential to address identified challenges. Member nations need to increase grid flexibility capacity to adequately prepare for higher penetrations of renewable electricity and lower overall system costs.
