How Texas unleashed a geothermal boom

News Feed
Saturday, April 20, 2024

With its nation-leading renewables fleet and oil and gas industry, Texas is poised to dominate what boosters hope will be America’s next great energy boom: a push to tap the heat of the subterranean earth for electricity and industry. That technology, known as geothermal energy, has demonstrated the rare ability to unite the state’s warring political camps — and is fueling a boom in startups that seek to take it national.  While other forms of renewable energy lost ground during Texas's 2021 and 2023 legislative sessions before a legislature that combined a hard-right political bent with a focus on building more "dispatchable" power, the geothermal industry advanced. State lawmakers passed four key bills in 2023  that helped lay the foundation for a new generation of drilling — with just one vote against.  In the 2023 session, "we didn't get put into the renewable bucket, we didn't really get put into the oil and gas bucket,” said Barry Smitherman, former Republican head of the state Railroad Commission and head of the Texas Geothermal Energy Alliance. Instead, “we became this hybrid that was acceptable to people on both sides of the aisle"​ The regulatory clarity established by those bills  has laid the groundwork for a new generation of startups powered by the state’s urgent need for reliable electricity in the face of increasingly extreme weather, as well as a growing trickle of oil and gas veterans leaving an industry they see as plagued by boom-and-bust cycles. As of last year, Texas had 11 of the 27 total geothermal startups in the US. On Wednesday, startup Bedrock Energy unveiled a new geothermal-powered heating and cooling system at a commercial real estate complex in Austin. Earlier this month, next-generation drilling company Quaise — which uses high powered radio waves to drill through hard rock — filed a permit with the state energy regulator to begin field testing its drills, years ahead of what industry insiders had thought was possible. Houston-based Fervo is building a 400-megawatt project in Utah. Military bases across the state are looking into geothermal as a potential source of secure electricity in an era of price spikes and cyberattacks. And later this year, Sage Geosystems, a company founded by three former Shell executives, will begin using a fracked well as a means of storing renewable energy — which CEO Cindy Taff said will get the company most of the way towards the ultimate goal of commercially viable geothermal electricity. The rise in geothermal startups comes alongside a broader surge in Texas renewable energy. Last month, solar generation eclipsed coal both in terms of power generation and market share. Texas also has more utility-scale wind and solar capacity than any other state, though it lags California when it comes to rooftop solar.  The Sage project shows the conceptual benefits of geothermal energy to the Texas grid, which increasingly runs on wind and solar energy. When the sun is high, the wind is blowing and demand is low, Sage will pump water into subterranean wells, creating zones of high pressure that utilities can tap as "batteries" when other energy supplies fall.  Though it lags California in total capacity, Texas is set to add the most utility scale batteries in the country in 2024, but these can only store power for two to six hours — creating a niche for projects like Sage, which aim to store power for up to a day. In building out its projects, Sage benefited from that nearly-unanimous package of legislative reforms passed by the during the notably acrimonious 2023 session, which opened the way to operators like Taff — and offered a potential roadmap to other oil and gas states looking to set up geothermal industries of their own. In its campaign for those pivotal laws, the geothermal lobby benefited from a recent traumatic experience for Texas: the brutal, deadly and staggeringly expensive legacy of 2021’s Winter Storm Uri. In addition to resulting in hundreds of deaths from freezing temperatures and carbon monoxide poisoning from generators, the storm left tens of millions across the state without power for nearly a week and caused electricity prices in Texas’s spot markets to soar to an unheard-of $9,000 per megawatt hour — costing ratepayers an estimated $17 billion in overcharges, a court ruled in 2023. The total cost was even higher: an estimated $300 billion, higher than that of Hurricane Katrina, according to the American Society of Civil Engineers. That tragedy was weaponized by both sides in the state’s frenetic culture wars. Republicans blamed the wind industry, which had 27 percent of its turbines freeze, according to a report from the Federal Energy Regulatory Commission (FERC). Meanwhile, Democrats blamed the lack of weatherization in the natural gas industry, which FERC found had lost 58 percent of its generation or pipeline capacity during the storm — undercutting the "firm" or "dispatchable" supply of energy needed to avert blackouts.  As Republicans sought to restrict the state’s burgeoning renewables industry, geothermal threaded the needle — aided by its lobbyists' deep ties to the oil industry and the Republican establishment. The lobby pushed the message of “geothermal as firm, dispatchable, 24/7, on-off switch, clean,” Smitherman told The Hill. “And it just resonated with everyone.” Lobbyists were “playing offense on three bills,” Smitherman said. First, in S.B. 785, the industry tackled the question of who owns geothermal heat — the subterranean energy that future projects will want to tap for industrial use or to generate electricity. That was a thorny question, because Texas law divides up surface rights — which include rights to land and the groundwater beneath — and mineral rights, which govern commodities like oil and gas below the surface.  During the fracking boom, that division created ugly situations in which mineral-rights holders allowed drilling rigs to operate on — and pollute — lands that they didn’t live on, sometimes against the wishes of the people on the site.  In S.B.785, legislators agreed with the industry that heat is legally more like water than oil — which makes the process of exploration substantially easier. For operators like Sage, Taff said, “that means we go in and we just really have to have an agreement with a landowner,” rather than having to sign separate deals with the mineral rights holder and landowner. S.B. 786 clarified that the geothermal industry is regulated by the Texas Railroad Commission, the state’s confusingly-named oil and gas regulator — rather than a mix of the commission, the state environmental regulator and the state utility commission for different aspects of the industry.  And in S.B. 1210, the legislature overwhelmingly voted that the state's thousands of “orphaned wells” — inactive, non-producing oil and gas wells — can be converted to geothermal wells without an additional permit. (As The Texas Tribune reported, Sage used one of these for a test well in south Texas.) Finally, in what Smitherman called “a defensive play,” the lobby worked to ensure through H.B. 5 that geothermal energy was eligible for the same tax breaks as other forms of dispatchable power — a privilege that would otherwise have only been available to coal, nuclear and natural gas. Together, these laws mean that a geothermal startup now just has to talk to a single regulator and a single rights holder; can cut costs on drilling using an existing well; and can realize tax breaks previously available only to far more established forms of power generation. It can also take advantage of the state’s burgeoning startup scene and huge oil and gas workforce — a necessary ingredient in a sector that is built on exploring the subsurface and drilling holes. For oil and gas workers, geothermal offers its own appeal. Part of this is emotional: Taff told the Tribune about how she moved to geothermal after a decade of being pressured by her daughter to leave the “dark side” of oil and gas for renewables — and found that geothermal offered her a chance to use her downhole experience in a way that wind and solar would not. ”That redemption arc is really, really inspiring for oil and gas people,” said Jamie Beard of Project Innerspace, a nonprofit geothermal advocacy group. Involvement in the industry lets former oil and gas workers “feel like they can use their entire life's work for something that they're going to be respected for — and right now they are villainized for,” she said. But in a state — and an energy sector — where belief in climate change remains controversial, geothermal can also make a more prosaic pitch: a stable job after the rollercoaster of oilfield work. “Oil and gas is very feast and famine,” Joselyn Lai, the CEO of Bedrock Energy, told The HIll.  “It's good times — and then it's like everyone's unemployed for like six months. There's definitely this hope and belief that the clean energy future will be one where there's more consistent jobs, and that it's where growth is happening.” That pitch comes as automation and efficiency have cut oilfield jobs — and as many projections suggest that oil demand will peak this decade, even as production is currently at record levels. One Bedrock employee who had specialized in well completions — the process of inserting pipe and bringing out oil and gas — described being laid off from an oil company because his job could be done by a worker in South Asia at a tenth the price. By drilling so many wells and dialing in their efficiency so much, he said, “we drilled ourselves out of a job.” Now he helps Bedrock drill 1,000 foot wells into the stable temperature of the subsurface, which can be used to dump heat in the summer or retrieve warmth in the winter — potentially offering commercial real estate clients a way to cut their heating and air conditioning costs by two to four times. That kind of project exemplifies a main part of geothermal’s appeal: It is a consistent product, which despite being zero-carbon offers the kind of electricity that utilities are used to working with.  The industry also faces serious challenges — particularly when it comes to securing financing to roll out and develop prototypes. First-of-their-kind geothermal projects often struggle to get across what the startup industry calls the “valley of death” — the dangerous period when they have secured initial investment and are paying for operations and payroll but aren’t yet making any money. (All of the companies listed in this article are in this difficult zone.)  Despite the promise of geothermal, many potential corporate partners “want to be first to go fifth,” Bedrock investor Gabriel Scheer of Elemental Excelerator, a nonprofit investment firm focused on climate technologies.  But for those investors who take the risk, Scheer said, there is the upside of getting a jump on a new technology — and getting to shape the way it unfolds. And in Texas specifically, the geothermal industry has certain distinct advantages. First, the experience of Winter Storm Uri means state businesses may be more focused on securing reliable heat and electricity than other states. Geothermal also benefits not just from the need to buttress the large wind and solar fleet, but also from the trail that those industries have blazed in terms of innovative forms of financing. In particular, virtually every wind and solar project in the state is built after developers sign a “power purchase agreement” with potential customers — something that the geothermal industry can easily adapt, said Dennis Wamsted of the Institute for Energy Economics and Financial Analysis. In Texas, Wamsted said, “Geothermal has the ability to come in and say, ‘You guys are familiar with all these contracts? Here, we are doing exactly the same thing.” Beard, the industry advocate, argued that Texas offers a model for other fossil fuel-rich states — like North Dakota or Pennsylvania — that want to transition their own industries. She was one of more than a dozen coauthors of “The Future of Geothermal in Texas,” a landmark 2023 report by five state universities that helped establish the industry’s bonafides before that year’s legislative session.  In the next six months, her team intends to replicate that report in ten such states, including Oklahoma and Pennsylvania. “The idea is, if you go into a state that has a big, significant oil and gas industry and you catalyze geothermal —  you all of a sudden have a bipartisan solution,” she said. Geothermal, she conceded “has really struggled on a federal level, with things like permitting and incentives.” But if such a research and lobbying effort were replicated across “all the oil and gas states, all of a sudden you have a federal coalition. You have movement on the federal level, and that’s the eventual outcome of all of the state work.” A national boom in geothermal would offer significant climate benefits. And in a world where the past pollution from oil and gas production is already anticipated to cut mid-century incomes by nearly 20 percent — even with aggressive climate action — it also has notable economic appeal. But in her pitch to investors or clients, Lai told The Hill, she doesn’t make the environmental pitch — because she doesn’t need to. At the end of the day, she said, “it's about the financial benefits.”

Greenpeace threatens to sue crown estate for driving up cost of offshore wind

Greenpeace is threatening to sue King Charles’s property management company, accusing it of exploiting its monopoly ownership of the seabed.The environmental lobby group alleges the crown estate has driven up costs for wind power developers and boosted its own profits, as well as the royal household’s income, due to the “aggressive” way it auctions seabed rights.The crown estate, as the legal owner of the seabed around England, Wales and Northern Ireland, is responsible for auctioning offshore wind rights. It has benefited from the huge growth in the industry, commanding hefty option fees from renewable energy developers to secure areas of the seabed to build their windfarms.It made a £1.1bn profit in its financial year ended in March, double its level just two years ago.Will McCallum, co-executive director at Greenpeace UK, said the estate should be “managing the seabed in the interest of the nation and the common good, not as an asset to be milked for profit and outrageous bonuses”.“We should leave no stone unturned in looking for solutions to lower energy bills that are causing misery to millions of households,” he said.“Given how crucial affordable bills and clean energy are to the government’s agenda, the chancellor should use her powers of direction to ask for an independent review of how these auctions are run. If the problem isn’t fixed before the next round, we may need to let a court decide whether or not what’s happening is lawful.”Greenpeace argues the crown estate has a legal duty not to exploit its monopoly position as owner of the seabed around England, Wales and Northern Ireland, but that it is now in breach of this.The lobby group said it was concerned the crown estate was rationing supply of the seabed to protect high prices, and argued this could harm the development of offshore wind power in the UK.The crown estate has reportedly rejected Greenpeace’s claims, arguing the lobby group has misinterpreted the estate’s legal duties.About 12% of crown estate profits flow to the monarchy to fund its work. This was lowered from 25% in 2023 to offset the rise in profits from offshore wind projects.skip past newsletter promotionOur morning email breaks down the key stories of the day, telling you what’s happening and why it mattersPrivacy Notice: Newsletters may contain information about charities, online ads, and content funded by outside parties.

The property assets in London, which is concentrated around Regent Street and St James’s, are valued at £7.1bn.A spokesperson for the crown estate said: “Greenpeace has misunderstood the crown estate’s legal duties and leasing processes. Option fees are not fixed by the crown estate. They are set by the developers through open, competitive auctions and reflect market appetite at the time. As our net revenue is returned to the Treasury, option fees help to ensure that taxpayers benefit from the requisite value from the development of our scarce and precious seabed resource.“The crown estate is accelerating offshore wind in line with government policy to move forward the energy transition at pace and improve energy security.”The Treasury was approached for comment.

New England’s final coal plant shuts down years ahead of schedule

Poor economics drove the aging New Hampshire plant offline three years early, even as the Trump administration pushes to revitalize coal.

Even as the federal government attempts to prop up the waning coal industry, New England’s last coal-fired power plant has ceased operations three years ahead of its planned retirement date. The closure of the New Hampshire facility paves the way for its owner to press ahead with an initiative to transform the site into a clean energy complex including solar panels and battery storage systems. “The end of coal is real, and it is here,” said Catherine Corkery, chapter director for Sierra Club New Hampshire. ​“We’re really excited about the next chapter.” News of the closure came on the same day the Trump administration announced plans to resuscitate the coal sector by opening millions of acres of federal land to mining operations and investing $625 million in life-extending upgrades for coal plants. The administration had already released a blueprint for rolling back coal-related environmental regulations. The announcement was the latest offensive in the administration’s pro-coal agenda. The federal government has twice extended the scheduled closure date of the coal-burning J.H. Campbell plant in Michigan, and U.S. Energy Secretary Chris Wright has declared it a mission of the administration to keep coal plants open, saying the facilities are needed to ensure grid reliability and lower prices. However, the closure in New Hampshire — so far undisputed by the federal government — demonstrates that prolonging operations at some facilities just doesn’t make economic sense for their owners. “Coal has been incredibly challenged in the New England market for over a decade,” said Dan Dolan, president of the New England Power Generators Association. Read Next Nobody wants this gas plant. Trump is forcing it to stay open. Rebecca Egan McCarthy Merrimack Station, a 438-megawatt power plant, came online in the 1960s and provided baseload power to the New England region for decades. Gradually, though, natural gas — which is cheaper and more efficient — took over the regional market. In 2000, gas-fired plants generated less than 15 percent of the region’s electricity; last year, they produced more than half. Additionally, solar power production accelerated from 2010 on, lowering demand on the grid during the day and creating more evening peaks. Coal plants take longer to ramp up production than other sources, and are therefore less economical for these shorter bursts of demand, Dolan said. In recent years, Merrimack operated only a few weeks annually. In 2024, the plant generated just 0.22 percent of the region’s electricity. It wasn’t making enough money to justify continued operations, observers said. The closure ​“is emblematic of the transition that has been occurring in the generation fleet in New England for many years,” Dolan said. ​“The combination of all those factors has meant that coal facilities are no longer economic in this market.” Granite Shore Power, the plant’s owner, first announced its intention to shutter Merrimack in March 2024, following years of protests and legal wrangling by environmental advocates. The company pledged to cease coal-fired operations by 2028 to settle a lawsuit claiming that the facility was in violation of the federal Clean Water Act. The agreement included another commitment to shut down the company’s Schiller plant in Portsmouth, New Hampshire, by the end of 2025; this smaller plant can burn coal but hasn’t done so since 2020. At the time, the company outlined a proposal to repurpose the 400-acre Merrimack site, just outside Concord, for clean energy projects, taking advantage of existing electric infrastructure to connect a 120-megawatt combined solar and battery storage system to the grid. It is not yet clear whether changes in federal renewable energy policies will affect this vision. In a statement announcing the Merrimack closure, Granite Shore Power was less specific about its plans than it had been, saying, ​“We continue to consider all opportunities for redevelopment” of the site, but declining to follow up with more detail. Still, advocates are looking ahead with optimism. “This is progress — there’s no doubt the math is there,” Corkery said. ​“It is never over until it is over, but I am very hopeful.” This story was originally published by Grist with the headline New England’s final coal plant shuts down years ahead of schedule on Oct 12, 2025.

Scientists Watch Fungi Evolve in Real Time, Thanks to a Marriage Proposal in a Cheese Cave

A new study pinpoints a disruption in a gene that made a beloved blue cheese's rind go from green to white

Scientists Watch Fungi Evolve in Real Time, Thanks to a Marriage Proposal in a Cheese Cave A new study pinpoints a disruption in a gene that made a beloved blue cheese’s rind go from green to white Sara Hashemi - Daily Correspondent October 10, 2025 3:27 p.m. The mold growing on batches of Bayley Hazen Blue cheese changed from green to white between 2016 and the present day. Benjamin Wolfe In 2016, Benjamin Wolfe, a microbiome scientist at Tufts University, was scheming. He’d convinced his former advisor, Rachel Dutton, to drive with him to Jasper Hill Farm in Greensboro, Vermont, to collect samples of a cheese called Bayley Hazen Blue. But the visit was about more than the sweet, creamy dairy product: It was a ruse so that Dutton’s boyfriend could propose at the farm, where they had first met. The surprise proposal went ahead as planned, and the biologist got his samples—scrapes from the cheese wheels’ rinds. He stored them in a freezer in his lab for years. “I’m notorious for not throwing samples away just in case we might need them,” he says in a statement. The cheese collected in 2016 was coated in a “very avocado-limey-green color,” Wolfe recalls to Elizabeth Preston at the New York Times. But a few years later, when graduate student Nicolas Louw went to pick up new samples at the farm, the rinds of the newer cheeses were completely white. The recipe hadn’t changed. Neither had the caves where the farm ages its blue cheese. Perhaps the mold had changed instead, the scientists surmised. “This was really exciting, because we thought it could be an example of evolution happening right before our eyes,” Wolfe says in the statement. “Microbes evolve. We know that from antibiotic resistance evolution [and] pathogen evolution, but we don’t usually see it happening at a specific place over time in a natural setting.” Did you know? A fungus among us According to a report from the American Academy of Microbiology, “Cheese is one of the few foods we eat that contains extraordinarily high numbers of living, metabolizing microbes.” Fungi are just the start—cheeses gain their flavors and textures from yeast (a type of fungus) and other microbes, like bacteria. Genetic analysis revealed the cheese rinds’ color change happened because of a disruption in ALB1, a gene involved in the production of melanin, which is known for its role in protection from ultraviolet (UV) radiation. In humans, melanin produces eye color as well as hair and skin pigmentation. In cheeses, melanin affects the appearance of the rind. It makes sense that fungi growing in a cave would shed a gene designed to produce melanin as it evolved, since it doesn’t need protection from ultraviolet light, Louw explains in the statement. The phenomenon, known as “relaxed selection,” is common in species that experience the removal of an environmental stressor. “By breaking that pathway and going from green to white, the fungi are essentially saving energy to invest in other things for survival and growth,” Louw says. The findings, published in the journal Current Biology last month, are a “perfect example of evolution in action,” Sam O’Donnell, a fungal genomicist at the University of Wisconsin–Madison who wasn’t involved in the work, tells the New York Times. Understanding how the Penicillium solitum fungi in the cheese evolve can also have other benefits. In the statement, the researchers say the work could be used to help prevent lung infections caused by other molds in the same family—or even help bolster global food security. “Around 20 percent of staple crops are lost pre-harvest due to fungal rot, and an additional 20 percent are lost to fungi post-harvest,” Louw says in the statement. “That includes the moldy bread in your pantry and rotting fruit on market shelves.” Being able to manage mold could help solve that issue. Next, Wolfe and his team will explore making new types of cheese with different tastes and textures based on their findings. They’ve already collaborated with the farm on a fresh brie with the white mold and found it tastes “nuttier and less funky,” Wolfe says in the statement. The cheeses will continue to be refined on the farm. “Seeing wild molds evolve right before our eyes over a period of a few years helps us think that we can develop a robust domestication process, to create new genetic diversity and tap into that for cheesemaking,” Wolfe adds. As for Dutton? She said yes. “We are very grateful to [her husband] for his elaborate marriage proposal,” the researchers note in the acknowledgments section of their paper. “It is because of his marriage proposal that the 2016 samples were collected.” Get the latest stories in your inbox every weekday.

State approves Zenith Energy’s air quality permit

The DEQ found Zenith was in compliance with state law, had met all applicable rules and regulations and had submitted a complete permit application, including an updated land-use credential issued by the city of Portland.

The Oregon Department of Environmental Quality has issued Zenith Energy’s air quality permit, allowing the controversial company to continue storing and loading crude oil and renewable fuels at a hub in Northwest Portland. State regulators issued the permit on Thursday after evaluating more than 800 written and 60 verbal comments, many of them opposing the permit. Zenith needed the permit approval to continue operations at the Critical Energy Infrastructure hub on the Willamette River. The Houston-based Zenith’s presence in Portland has attracted fierce backlash in recent years from environmental activists and some city residents concerned with the company’s myriad violations and the potential for fuel spills and explosions in the event of a large earthquake in the region. Zenith is one of 11 fuel companies at the hub.Lisa Ball, an air quality permit manager with DEQ, said the agency issued the permit because it found Zenith was in compliance with state law, had met all applicable rules and regulations and had submitted a complete permit application, including an updated land-use credential issued by the city of Portland. The new permit requires less frequent state inspections and company reporting requirements than Zenith’s previous permit, Ball said, though the department retains the authority to inspect the company as needed or in the case of violations. Ball said the new permit is also more stringent than Zenith’s previous permit because it prohibits crude oil storage and loading starting in October 2027 and includes stricter emission standards. It requires Zenith to reduce by 80% the amount of emitted volatile organic compounds, known as VOCs, a group of air pollutants that can cause irritation to the eyes, nose and throat, damage to the liver, kidney and central nervous system and, in some cases, cause cancer. It also adds PM 2.5 and greenhouse gases – chiefly carbon dioxide – to the company’s regulated pollutants. PM 2.5 are tiny particles that are small enough to penetrate deep into the lungs and even enter the bloodstream. “This permit is more protective of human health and the environment,” Ball said.Environmental groups have disputed that characterization and said their own analysis – submitted as part of the public comments on the permit application – shows Zenith will not meet the emissions limits in the newly granted permit. “DEQ chose to accept Zenith’s mathematical sleight of hand despite expert analysis showing real-world pollution will be much worse,” said Audrey Leonard, an attorney with Columbia Riverkeeper, a Hood River-based environmental group focused on protecting the river. “The public knows better – Zenith’s expansion of so-called renewable fuels will result in more harm to our rivers, air and communities.” A previous analysis of Zenith’s draft air quality permit application by The Oregonian/OregonLive showed the permit, if approved, was not likely to lead to substantial emission reductions because Zenith is currently emitting far below the cap of its previous permit limits. The analysis also found the permit would likely pave the way for Zenith to significantly expand the amount of fuel it stores in Portland because renewable fuels such as renewable diesel or renewable naphta produce less pollution, allowing the company to store more of them without going over the permit limits. Zenith officials praised the permit approval and said the company’s transition to renewable fuel storage would ensure Oregon has the supply it needs to meet its carbon reduction goals. “The infrastructure investments being made during this transition will also ensure our terminal continues to operate at the highest standards of safety. We look forward to supporting regional leaders in creating a lower-carbon future,” Zenith’s chief commercial officer Grady Reamer said in a statement. In the meantime, Portland is still in the midst of an investigation into the potential violations of Zenith Energy’s franchise agreement, including whether Zenith violated the law when it constructed and used new pipes at an additional dock on the river – without reporting it to authorities – to load renewable and fossil fuels. City officials have said the investigation would likely conclude by the end of the year. Also ongoing: a legal challenge over the city’s land-use approval for Zenith, filed by environmental groups with the Oregon Land Use Board of Appeals. Portland officials have had a complex relationship with the company. The city denied Zenith’s land-use credential in 2001 and defended the decision in court before reversing course and approving it with the condition that Zenith transition to renewable fuels and secure a new air permit with more stringent emission limits. In February, despite mounting opposition from local activists, city staff once again approved a land-use credential for Zenith.The approval came after DEQ last year found Zenith had been using the McCall dock and pipes to load and unload fuels without authorization. As part of the sanctions, DEQ officials required Zenith to seek a new land-use approval before continuing its air quality permit process.DEQ officials said they would reevaluate Zenith’s air permit if the legal case or city investigation led to any changes to the status of the land-use approval – such as if the city revoked it or the state land use panel invalidated it.The newly issued air permit is valid for five years.

Renewables have now passed coal globally – and growth is fastest in countries like Bhutan and Nepal

Even as clean energy progress slows in the US and EU, developing nations such as Bhutan, Nepal, Sri Lanka and the Maldives are surging ahead.

Commuters pass a new solar array in the Maldives. Ishara S. Kodikara/GettyFor the first time, renewables have toppled coal as the world’s leading source of electricity, in keeping with International Energy Agency projections for this historic shift. But progress is uneven. The shift away from fossil fuels has slowed in the United States and the European Union – but accelerated sharply in developing nations. China attracts headlines for the sheer scale of its shift. But many smaller nations are now taking up clean energy, electric vehicles and battery storage at remarkable speed, driven by governments, businesses and individuals. Importantly, these moves often aren’t about climate change. Reasons range from cutting dependence on expensive fossil fuels and international market volatility to reducing reliance on unreliable power grids to finding ways to boost livelihoods. Pakistan’s enormous solar boom is partly a response to spiking power prices and grid unreliability. Meanwhile Pacific nations see clean energy as a way to slash the crippling cost of importing diesel and expand electricity access. My research has given me insight into the paths four countries in South Asia have taken to seize the benefits of clean technology, each shaped by unique pressures and opportunities. All are moving rapidly, blending necessity with ambition. Their stories show the clean energy path isn’t one-size-fits-all. Bhutan: from hydropower giant to diversified energy The landlocked Himalayan kingdom of Bhutan has long relied on hydroelectricity. But the country faces a persistent challenge: seasonal variability. Most of Bhutan’s plants are run-of-the-river, meaning they don’t have large dams. As a result, power generation drops sharply during dry winter months when river flows are low, particularly between January and April. At the same time, rapid industrialisation has driven up demand for power, outstripping winter capacity. Climate change is expected to worsen this variability. During these months, Bhutan shifts from its role as clean-energy exporter to an importer, buying electricity from India. But imports aren’t a long-term solution. To secure reliable supply year-round, Bhutan’s government is diversifying energy sources. To that end, up to 300 megawatts of solar is expected to be installed, potentially as soon as next year. Bhutan’s first utility-scale solar farm is under construction. Over time, Bhutan will blend hydro with solar, wind and biomass to create a more balanced clean energy mix. Bhutan has long relied on hydroelectricity. But authorities are moving to find new sources of power as demand surges and river flows become less reliable. Kuni Takahashi/Getty Nepal: electric cars in Kathmandu Nepal has long imported all its petrol from India. But when India launched an unofficial blockade in 2015, vital supplies and fuel tankers stopped coming. Fuel prices surged. People queued for days at petrol stations, while black-market prices soared and public transport collapsed. Households, already enduring many hours of daily blackouts, faced even worse conditions. The crisis exposed Nepal’s deep vulnerability. The mountainous nation makes its own electricity, largely through hydropower. But it had to import petrol. In 2018, authorities launched an ambitious program to shift to electric vehicles and free the nation from dependence on imports. Electric vehicles would charge on domestic hydropower and reduce Kathmandu’s well-known air pollution. The plan called for electric vehicles to reach 90% share of new commuter vehicle sales (including popular two-wheelers) by 2030. This year, the electric vehicle share for new four-wheel vehicles reached 76%, jumping rapidly in just the past year. Exemptions and incentives have supported this growth. As electric vehicles surge, new charging station and maintenance businesses have emerged. It’s not all smooth sailing. A protest movement recently overthrew Nepal’s government, creating uncertainty. Analysts warn stable government policy and infrastructure investment will be essential. Electric vehicles are soaring in popularity in Nepal.

Chinese News Service/Getty Sri Lanka: innovation emerging from crisis Between 2022 and 2023, a serious economic crisis hit Sri Lanka. Citizens reeled from severe energy shocks, such as fuel shortages, 12-hour blackouts and punishing electricity price hikes of over 140%. Half a million people were disconnected from the grid as they were unable to pay. The crisis showed how fragile the island nation’s energy system was. Authorities looked for better options. Hydroelectricity has long been a mainstay, but solar and wind are growing rapidly. Sri Lanka runs on about 50% renewables, with hydro the largest contributor by far. By 2030, the goal is to reach 70% renewable energy. While renewables offer cheap power, they have to be coupled with energy storage and new systems to integrate them into the grid. In response, universities, international partners and companies have worked to integrate renewable energy in the grid, developing artificial intelligence-based systems to improve reliability and supply to consumers. For instance, they can reduce voltage fluctuations associated with high uptake of rooftop solar. Importantly, some of these projects have a gender focus, prioritising women-led small enterprises and training for women engineers. The crisis may prove a turning point by exposing vulnerabilities and pushing Sri Lanka to adopt new energy solutions. After a severe energy crisis gripped Sri Lanka, authorities began looking for ways to reduce reliance on imported fossil fuels.

Kodikara/Getty Maldives: bringing solar to diesel-dependent islands Few countries are more vulnerable to fossil fuel dependence than the Maldives. Spread across 1,000 islands, the nation relies on imported diesel for power generation, with high transport costs and exposure to oil price swings. In 2014, Maldivian authorities launched the Preparing Outer Islands for Sustainable Energy Development project as part of a plan to reach net-zero by 2030. The project focuses on around 160 poorer islands further from the capital, progressively replacing a reliance on diesel generators with solar arrays, battery storage and upgraded power grids. Women’s economic empowerment is a priority, as women-led enterprises run solar systems and utilities train female operations officers. The Maldives government released a 2030 roadmap, which has a welcome focus on the “just energy transition” – ensuring communities benefit equitably. For the Maldives, renewables are more than an environmental choice — they are a lifeline for economic survival and resilience. Lessons from the margins While these energy transitions rarely make global headlines, Bhutan, Nepal, Sri Lanka and the Maldives show how smaller economies are finding their own pathways to cleaner, more resilient energy. Their reasons to act stem from different crises, from blockades to economic upheaval. But each nation is working to turn challenge into opportunity. Reihana Mohideen has previously consulted for the POISED project in the Maldives.
