We’re now a quarter of the way through the 21st century, and it’s indisputable that climate is one of the most important stories of our time. That’s our philosophy here at Heatmap, but just about everything around us illustrates it, too — from government policy and tech to movies and reality TV.
And of course — or maybe, especially — books.
It’s been about 17 years since the term “cli-fi” (or “climate fiction”) was first coined, and in the meantime, books that touch on climate themes in both fiction and nonfiction have taken off like the Keeling Curve. In 2025, we’ll be reading novels that imagine life in San Francisco after years of deluge and investigative reports into subjects such as how companies have gotten away with dumping forever chemicals into the environment for so long. There will be new natural histories to dive into — on the desert, forests, prairies, and even on the chemical compound CO2 — as well as new frames of thinking about climate change and how we approach its solutions.
Because so many 2025 books will touch on climate themes, I’ve set aside a section of honorable mentions at the end of this list that are also worth checking out. The division doesn’t indicate quality; I chose the primary 18 based on my subjective excitement and to showcase different genres, publishers, and authors. It might be in the appendix that you find a book on the topic you’re personally most excited about (Arctic exploration? Solar geoengineering? Florida-set family dramas?) for next year.
Finally, if you want to see all these books in one place or judge them by their (excellent) covers, you can browse our curated list on Bookshop here.
The U.S. government’s Fifth National Climate Assessment section on the Southwest reads like an apocalyptic horror story: “Heat-related mortality,” “increased wildfire risks,” and “longer and more severe droughts” all make it into the opening few paragraphs. The truth is that the hottest and driest region of the United States is home to 60 million people, many of whom will have to adapt to a more extreme future in the coming years. In New Mexico-born journalist Kyle Paoletta’s debut book, American Oasis, he traces the allure of places like Albuquerque, Phoenix, El Paso, and Las Vegas back to the Athapaskan migration from the sub-Arctic around 1100 BCE and through the heydays of Arizona Highways, a magazine from the 1950s, while also charting what lies ahead for those who are drawn to making the desert, however impossibly, their home. Preorder it here.
Speaking of the American desert, on the fiction side of things this winter comes Madeleine Watts’ latest novel, Elegy, Southwest. Watts made a name for herself as a writer of cli-fi after the release of her 2021 novel, The Inland Sea, set against the backdrop of Australia’s fires and floods, and she returns this year with a road trip novel that follows Eloise, a doctoral student studying the Colorado River and climate change. As part of her research, Eloise flies to Las Vegas for a road trip through the Southwest with her husband, Lewis, to whom the novel is addressed. Along the way, Eloise begins to believe she’s pregnant, while Lewis struggles with the fresh grief of losing his mother. As Watts told an interviewer of her process for The Inland Sea, “I wanted to write … about what it’s like to live in the experience of a changing climate that is not always a tangible part of your day-to-day but that’s already there – it’s in the air all around you.” Expect a similar treatment this go-round. Preorder it here.
Eric Puchner’s new novel, Dream State, is the story of two marriages set over 50 years. With the book opening in 2004, that naturally requires some speculation about the future — in this case, the future of “a rapidly warming Montana.” As The Indypendent writes in an early review, “The looming climate crisis — declining snowfall, depleted wildlife, raging seasonal wildfires, and abnormally warm temperatures — is writ large in the book, forming a blistering backdrop, highlighting newfound restrictions on what both residents and short-term visitors can now see and do in the area.” The novel has earned praise from Pulitzer Prize-winner Adam Johnson, who called it “a masterpiece,” as well as author Lynn Steger Strong, who has a climate book of her own on the list below. Preorder it here.
Four years ago, Argentinean author Agustina Bazterrica burst onto Americans’ radars with the English-language translation of her 2017 novel Tender Is the Flesh, a book that imagines a future in which animals have become toxic to humans, leading us to resort to industrialized cannibalism. (Critics have described it, vividly, as “splatterpunk.”) This year, Bazterrica turns her attention from factory farming to the climate catastrophe, telling the story of a member of a “Sacred Sisterhood” cloistered in a mysterious convent who is prompted to reflect on her life outside its walls when a new acolyte arrives. Don’t expect Bazterrica to soften her critiques of capitalism here, though it’s not all doom and gloom; early readers have said The Unworthy “ends on a light note of hope.” Preorder it here.
Charlotte McConaghy’s follow-up novel to her critically acclaimed 2020 debut, Migrations, is set on a fictional research island, Shearwater, located between Australia and Antarctica. Dominic Salt, the caretaker of the island’s seed vault, has called the refuge home for the past eight years — ever since fleeing Australia’s accelerating natural disasters, hoping to find a safer place to raise his three children. But with rising sea levels now threatening the island, Dominic and his family have just seven weeks left before they plan to move on. Just before their departure, Dominic’s oldest daughter discovers a woman who has shipwrecked on shore, and the tension — and mystery — starts to grow. Wild Dark Shore has earned a starred review from Kirkus, which calls it a “terrific thriller.” Preorder it here.
Climatologist, World Weather Attribution co-founder, and 2024 Trailblazing Women in Climate laureate Friederike Otto does not mince words about who is most impacted by extreme weather — and who needs to be involved in the solutions. “If we leave the issue of climate change to white men, it’ll continue to be treated as a physical problem with technological solutions,” she has said, adding, “The more diverse the people working on it, the closer we get to implementing these solutions and making progress on climate change.” Her new book, Climate Injustice, elaborates on her thesis further, using the stories of real people in the Global South to illustrate how exploitation, sexism, and colonialism have created a crisis with unequal impacts. Preorder it here.
Everyone who works in the climate space is familiar with the question posed in the title of this book. Entomologist Douglas W. Tallamy is one of the leading proponents of the native gardens movement, and in How Can I Help?, he answers a query implied in his own earlier book, 2009’s Bringing Nature Home: that “unless we restore native plants to our suburban ecosystems, the future of biodiversity in the United States is dim.” How Can I Help? is structured to address some of the most common questions Tallamy encounters during his lectures about how individuals can become directors of their own miniature national parks at home. Despite the daunting challenge of biodiversity loss, Tallamy offers actionable ideas for helping the planet, with conservation beginning in your backyard. Preorder it here.
If I had to make one prediction for 2025, it’d be that we will hear a lot more about per- and polyfluoroalkyl substances — that is, the “forever chemicals” commonly known as PFAS. The chemicals are found in everything from our dental floss to our clothes, but perhaps most disturbingly, they’re also found in our drinking water. In Poisoning the Well, The Hill staff writers Sharon Udasin and Rachel Frazin follow how PFAS got into our environment in the first place — a story of corporate greed and cover-ups that will be familiar to anyone aware of the fossil fuel playbook. Preorder it here.
Journalist Malcolm Harris’ last book was an “encyclopedic,” 700-page history of the city of Palo Alto, which became a fixture of best-of-the-year lists after it came out last February. Hot on its heels is Harris’ follow-up, What’s Left (which slow readers will be relieved to hear is less of a time commitment, at 320 pages). Harris’ intention with his new work is to explore “our remaining options for saving the world,” all of which involve varying degrees of collective action but which escalate from “progressive” to “socialist” to “revolutionary.” It’s one that you can be sure will have people talking. Preorder it here.
Alan Weisman’s hugely successful 2007 book, The World Without Us, speculated about humanity’s legacy if we suddenly disappeared. (Slate named it in 2019 as one of the 50 best nonfiction books in the past quarter-century.) Now, Weisman turns his attention to helping us stick around. “I am working on a book with kind of a vast topic, which is what are humanity’s best and most realistic hopes for getting through this very difficult century that we have,” he told Bangladesh’s Business Standard in 2022, while visiting the country during the research stage of his new project, Hope Dies Last. Weisman’s book took him all over the world — including the Korean de-militarized zone, the Netherlands, and the Marshall Islands — as he looked to speak with people across disciplines and professions about how we can approach our future. Bill McKibben has described the result as “a nonfiction companion to Kim Stanley Robinson’s Ministry for the Future.” Preorder it here.
In 1999, 24-year-old environmentalist Terence Unity Freitas traveled to Colombia to support the Indigenous U’wa people in resisting Occidental Petroleum, which was interested in drilling to extract some 1.5 billion barrels of oil from beneath the cloud forest. During what was supposed to be a weeklong visit, Freitas was kidnapped by the Armed Revolutionary Forces of Colombia (better known as FARC) along with two other Americans; their bodies were later found, bound and shot, just over the border in Venezuela. Twenty years later, Abby Reyes — the author of this memoir and Freitas’ partner at the time of his death — was recognized as a victim in Colombia’s truth and reconciliation process, resurfacing old griefs, reflections, and questions. “I bring the reader along in my demand for truth before the tribunal while awakening our collective awareness of what the truth demands of all of us in this era of ecological collapse and social transformation,” Reyes has said of her book.

In Susanna Kwan’s debut novel, Awake in the Floating City, San Francisco is almost entirely underwater. Years of Biblical rain mean most people have already evacuated, but Bo — who lost her mother to the waters — lingers long past when sensible people have fled. Then one day, she receives a note from her neighbor, Mia, a 130-year-old woman who doesn’t want to leave the city, either; together, the two become the last people left in San Francisco. “What post-apocalyptic vision dares be so gorgeous?” marvels the author Meng Jin in one of the book’s early blurbs. Preorder it here.
Identical twin sister arborists teach the Women’s Tree Climbing Workshop. While that sounds like the beginning of a fairy tale, it’s the delightfully real-life starting point of journalist Marguerite Holloway’s Take to the Trees. “I was there to be in trees and to better understand them,” she writes of her attendance at the climbing workshop. “Trees and forests are facing existential threats because of climate change, but it can be a struggle to grasp the extent of the danger.” While not all of us have the time, ability, or inclination to take to such “gut-lurching” heights to learn more, we can read Take to the Trees, which records Holloway’s experience overcoming her fears and learning to appreciate the threat to American forests. Preorder it here.
Natural history is one of my favorite genres, and I’m especially excited for Sea of Grass by Minnesota Star Tribute journalists Dave Hage and Josephine Marcotty about one of the more neglected ecosystems of the genre: the American prairie. The grassland, which makes up a vast swath of the inner United States, is an incredible self-sustaining marvel — and nearly as biodiverse as a tropical rainforest. Yet many people today still either share European settlers’ disinterested view of the landscape or adopt a purely utilitarian one — which is why, after 200 years of plows, drainages, and nitrogen fertilizers, the effects have been “catastrophic.” Still, plenty of people who live on the prairie understand the importance of protecting such a special ecosystem, and Hage and Marcotty follow the effort to work alongside the land, not just against it. Sea of Grass earned a coveted blurb from McKibben, in which he calls the book “well worth the read.” Preorder it here.
We’ve been attempting to predict the weather for as long as humans have existed. Satellites, radars, and computers helped us make a significant leap forward from the days of farmer’s almanacs, but advances in artificial intelligence, drones, and the proliferation of home weather stations have created previously unimaginable opportunities for accuracy. (It’s a tech frontier we’ve covered quite a bit here at Heatmap, as well). In his book, Journalist Thomas E. Weber dives into the wild — and wildly important — world of forecasting, which will hit shelves just in time for hurricane season. Preorder it here.
Climate scientist and Shift Key guest Kate Marvel structured her highly anticipated first book around nine different emotional lenses for looking at climate change. That might seem like an odd angle for a scientist, since researchers are specifically taught not to bring emotion into their work. Still, she contends that just as there is no one way to feel about climate change, there is no one emotion we can tap to guide our response to it, either. From hope to pride to love, Marvel urges readers to get deep into their feels in Human Nature, which also touches on “Greek mythology,” “witches,” “geophysical fluid dynamics,” and “romantic comedies” — though according to Marvel, you won’t find “despair” in its pages. A 120,000-copy initial print run suggests the publisher, Ecco, believes this one will be a hit. Preorder it here.
Addressing climate change will require us to address how we eat, which accounts for a third of our carbon emissions. How to ameliorate that is one of the most significant questions we’re currently staring down as a species — and the topic of journalist and Heatmap contributor Michael Grunwald’s next book. Though the answers he finds might not always fit into our comfortable narratives — Grunwald recently ruffled feathers with a related piece for The New York Times defending industrial agriculture’s high yields on small parcels of land as our “best hope” — We Are Eating the Earth seems certain to reshape how its readers think about food, policy, and our thrice-daily consumptions. I can’t wait to be challenged by it. Preorder it here.
Science journalist Peter Brannen’s last book was about the five times life on our planet almost ended in mass extinctions. His follow-up, The Story of CO2 Is the Story of Everything, will zero in on the collection of molecules that have allowed life to exist in the first place. Of course, the great irony of carbon dioxide is that while it has made our planet habitable, fluctuations in its presence in the atmosphere are also responsible for things like almost killing our ancestors all off in an event known as the Great Dying — and now, of course, we have put our thumb on that scale. By looking backward, often by many millions of years, Brennen gives us a glimpse of our future. You’ll definitely want to preorder this book, if only because it will look great on the shelf next to Brennen’s other Eric Nyquist-designed cover. Preorder it here.

Representatives Jake Auchincloss and Mark Amodei want to boost “superhot” exploration.
Geothermal is about the only energy topic that Republicans and Democrats can agree on.
“Democrats like clean energy. Republicans like drilling. And everyone likes baseload power that is generated with less than 1% of the land and materials of other renewables,” Massachusetts Representative Jake Auchincloss, a Democrat, told me.
Along with Republican Representative Mark Amodei of Nevada, Auchincloss is introducing the Hot Rock Act on Friday, focusing specifically on “superhot” or “supercritical” geothermal resources, i.e. heat deposits 300 degrees Celsius or above. (Temperatures in large traditional geothermal resources are closer to 240 degrees.)
The bill — of which Heatmap got an exclusive early peek — takes a broad approach to supporting research in the sector, which is currently being explored by startups such as Quaise Energy and Mazama Energy, which in October announced a well at 331 degrees.
There’s superhot rock energy potential in around 13% of North America, modeling by the Clean Air Task Force has found — though that’s mostly around 8 miles below ground. The largest traditional geothermal facility in the U.S. is only about 2.5 miles at its deepest.
But the potential is enormous. “Just 1% of North America’s superhot rock resource has the potential to provide 7.5 terawatts of energy capacity,” CATF said. That’s compared to a little over a terawatt of current capacity.
Auchincloss and Amodei’s bill would direct the Department of Energy to establish “milestone-based research grant programs,” under which organizations that hit goals such as drilling to a specific depth, pressure, or temperature would then earn rewards. It would also instruct the DOE to create a facility “to test, experiment with, and demonstrate hot dry rock geothermal projects,” plus start a workforce training program for the geothermal industry.
Finally, it would grant a categorical exclusion from the National Environmental Policy Act for drilling to explore or confirm geothermal resources, which could turn a process that takes over a year into one that takes just a couple of months.
Geothermal policy is typically a bipartisan activity pursued by senators and House members from the Intermountain West. Auchincloss, however, is a New Englander. He told me that he was introduced to geothermal when he hosted an event in 2022 attended by executives from Quaise, which was born out of the Massachusetts Institute of Technology.
It turned out the company’s pilot project was in Nevada, and “I saw it was in Mark Amodei’s district. And I saw that Mark is on Natural Resources, which is the other committee of jurisdiction. And so I went up to him on the floor, and I was like, Hey there, you know, there's this company announcing this pilot,” Auchincloss told me.
In a statement, Amodei said that “Nevada has the potential to unlock this resource and lead the nation in reliable, clean energy. From powering rural communities and strengthening critical mineral production to meeting the growing demands of data centers, geothermal energy delivers dependable 24/7 power.”
Auchincloss told me that the bill “started from the simple premise of, How do we promote this technology?” They consulted climate and technology experts before reaching consensus on the milestone-based payments, workforce development, and regulatory relief components.
“I didn't have an ideological bent about the right way to do it,” Auchincloss said.
The bill has won plaudits from a range of industry groups, including the Clean Energy Buyers Association and Quaise itself, as well as environmental and policy organizations focused on technological development, like the Institute for Progress, Third Way, and the Breakthrough Institute.
“Our grassroots volunteers nationwide are eager to see more clean energy options in the United States, and many of them are excited by the promise of reliable, around-the-clock clean power from next-generation geothermal energy,” Jennifer Tyler, VP government affairs at the Citizens' Climate Lobby, said in a statement the lawmakers provided to Heatmap. “The Hot Rock Act takes a positive step toward realizing that promise by making critical investments in research, demonstration, and workforce development that can unlock superhot geothermal resources safely and responsibly.”
With even the Trump administration generally pro-geothermal, Auchincloss told me he’s optimistic about the bill’s prospects. “I expect this could command broad bipartisan support,” he said.
Plus a pre-seed round for a moon tech company from Latvia.
The nuclear headlines just keep stacking up. This week, Inertial Enterprises landed one of the largest Series A rounds I’ve ever seen, making it an instant contender in the race to commercialize fusion energy. Meanwhile, there was a smaller raise for a company aiming to squeeze more juice out of the reactors we already have.
Elsewhere over in Latvia, investors are backing an early stage bid to bring power infrastructure to the moon, while in France, yet another ultra-long-duration battery energy storage company has successfully piloted their tech.
Inertia Enterprises, yet another fusion energy startup, raised an eye-popping $450 million Series A round this week, led by Bessemer Venture Partners with participation from Alphabet’s venture arm GV, among others. Founded in 2024 and officially launched last summer, the company aims to develop a commercial fusion reactor based on the only experiment yet to achieve scientific breakeven, the point at which a fusion reaction generates more energy than it took to initiate it.
This milestone was first reached in 2022 at Lawrence Livermore National Laboratory’s National Ignition Facility, using an approach known as inertial confinement fusion. In this method, powerful lasers fire at a small pellet of fusion fuel, compressing it until the extremely high temperature and pressure cause the atoms inside to fuse and release energy. Annie Kritcher, who leads LLNL’s inertial confinement fusion program, is one of the cofounders of Inertia, alongside Twilio co-founder Jeff Lawson and Stanford professor Mike Dunne, who formerly led a program at the lab to design a power plant based on its approach to fusion.
The Inertia team plans to commercialize LLNL’s breakthrough by developing a new fusion laser system it’s calling Thunderwall, which it says will be 50 times more powerful than any laser of its type to date. Inertia isn’t the only player trying to commercialize laser-driven fusion energy — Xcimer Energy, for example, raised a $100 million Series A in 2024 — but with its recent financing, it’s now by far the best capitalized of the bunch.
As Lawson, the CEO of the new endeavor said in the company’s press release, “Our plan is clear: build on proven science to develop the technology and supply chain required to deliver the world’s highest average power laser, the first fusion target assembly plant, and the first gigawatt, utility-scale fusion power plant to the grid.” Great, but how soon can they do it? The goal, he says, is to “make this real within the next decade.”
In more nuclear news, the startup Alva Energy launched from stealth on Thursday with $33 million in funding and a proposal to squeeze more capacity out of the existing nuclear fleet by retrofitting pressurized-water reactors. The round was led by the venture firm Playground Global.
The startup plans to boost capacity by building new steam turbines and electricity generators adjacent to existing facilities, such that plants can stay online during the upgrade. Then when a plant shuts down for scheduled maintenance, Alva will upgrade its steam generator within the nuclear containment dome. That will allow the system to make 20% to 30% more steam, to be handled by the newly built turbine-generator system.
The company estimates that these retrofits will boost each reactor’s output by 200 megawatts to 300 megawatts. Applied across the dozens of existing facilities that could be similarly upgraded, Alva says this strategy could yield roughly 10 new gigawatts of additional nuclear capacity through the 2030s — the equivalent of building about 10 new large reactors.
Biden’s Department of Energy identified this strategy, known as “uprating”, as capable of adding 2 gigawatts to 8 gigawatts of new capacity to the grid. Alva thinks it can go further. The company promises to manage the entire uprate process from ensuring regulatory compliance to the procurement and installation of new reactor components. The company says its upgrades could be deployed as quickly as gas turbines are today — a five- to six-year timeline — at a comparable cost of around $1 billion per gigawatt.
Deep Space Energy, a Latvian space tech startup, has closed a pre-seed funding round to advance its goal of becoming a commercial supplier of electricity for space missions on the moon, Mars, or even deeper into space where sunlight is scarce. The company is developing power systems that convert heat from the natural decay of radioisotopes — unstable atoms that emit radiation as they decay — into electricity.
While it’s still very early-stage, this tech’s first application will likely be backup power for defense satellites. Long term, Deep Space Energy says it “aims to focus on the moon economy” by powering rovers and other lunar installations, supporting Europe’s goal of increasing its space sovereignty by reducing its reliance on U.S. defense assets such as satellites. While radioisotope generators are already used in some space missions, the company says its system requires five times less fuel than existing designs.
Roughly $400,000 of the funding came from equity investments from the Baltic-focused VC Outlast Fund and a Lithuanian angel investor. The company also secured nearly $700,000 from public contracts and grants from the European Space Agency, the Latvian Government, and a NATO program to accelerate innovation with dual-use potential for both defense and commercial applications.
As I wrote a few weeks ago, Form Energy’s iron-air battery isn’t the only player targeting 100-plus hours of low-cost energy storage. In that piece, I highlighted Noon Energy, a startup that recently demoed its solid-oxide fuel cell system. But there’s another company aiming to compete even more directly with Form by bringing its own iron-air battery to the European market: Ore Energy. And it just completed a grid-connected pilot, something Form has yet to do.
Ore piloted its 100-hour battery at an R&D center in France run by EDF, the state-owned electric utility company. While the company didn’t disclose the battery’s size, it said the pilot demonstrated its ability to discharge energy continuously for about four days while integrating with real-world grid operations. The test was supported by the European Union’s Storage Research Infrastructure Eco-System, which aims to accelerate the development of innovative storage solutions, and builds on the startup’s earlier grid-connected installation at a climate tech testbed in the Netherlands last summer.
Founded in 2023, Ore plans to scale quickly. As Bas Kil, the company’s business development lead, told Latitude Media after its first pilot went live, “We’re not planning to do years and years of pilot-scale [projects]; we believe that our system is now ready for commercial deployment.” According to Latitude, Ore aims to reach 50 gigawatt-hours of storage per year by 2030, an ambitious goal considering its initial grid-connected battery had less than one megawatt-hour of capacity. So far, the company has raised just shy of $30 million to date, compared to Form’s $1.2 billion.
Battery storage manufacturer and virtual power plant operator Sonnen, together with the clean energy financing company Solrite, have launched a Texas-based VPP composed exclusively of home batteries. They’re offering customers a Solrite-owned 60-kilowatt-hour battery for a $20 monthly fee, in exchange for a fixed retail electricity rate of 12 cents per kilowatt-hour — a few cents lower than the market’s average — and the backup power capability inherent to the system. Over 3,000 customers have already enrolled, and the companies are expecting up to 10,000 customers to join by year’s end.
The program is targeting Texans with residential solar who previously sold their excess electricity back to the grid. But now that there’s so much cheap, utility-scale solar available in Texas, electricity retailers simply aren’t as incentivized to offer homeowners favorable rates. This has left many residents with “stranded” solar assets, turning them into what the companies call “solar orphans” in need of a new way to make money on their solar investment. Customers without rooftop solar can participate in the program as well, though they don’t get a catchy moniker.
Current conditions: It looks like rain on Valentine’s Day across the South • Storm Nils is battering France with heavy rain and gales of up to 100 miles per hour • A Northeast Monsoon, known locally as an Amihan, is flooding the northern Philippine island of Luzon, threatening mudslides.
President Donald Trump has done what he didn’t dare attempt during his first term, repealing the finding that provided the legal basis for virtually all federal regulations to curb greenhouse gas emissions. By rescinding the 2009 “endangerment finding,” which established that planet-heating emissions harm human health and therefore qualify for restrictions under the Clean Air Act, the Trump administration hopes to unwind all rules on pollution from tailpipes, trucks, power plants, pipelines, and drilling sites all in one fell swoop. “This is about as big as it gets,” Trump said alongside Environmental Protection Agency Administrator Lee Zeldin at a White House event Thursday.
The repeal, which is sure to face legal challenges, opens up what Reuters called a new front in the legal wars over climate change. Until now, the Supreme Court had declined to hear so-called public nuisance cases brought by activists against fossil fuel companies on the grounds that the legal question of emissions was being sorted out through federal regulations. By eliminating those rules outright, litigants could once again have new standing to sue over greenhouse gas emissions. To catch up on the endangerment finding in general, Heatmap’s Robinson Meyer and Emily Pontecorvo put together a handy explainer here.
A bill winding its way through Ohio’s Republican-controlled state legislature would put new restrictions on development of wind and solar projects. The state already makes solar and wind developers jump over what Canary Media called extra hurdles that “don’t apply to fossil-fueled or nuclear power plants, including counties’ ability to ban projects.” For example, siting authorities defer to local opposition on renewable energy but “grant opponents little say over where drilling rigs and fracking waste can go.”
The new legislation would make it state policy “in all cases” for new power plants to “employ affordable, reliable, and clean energy sources.” What qualifies as “affordable, reliable, and clean”? Pretty much everything except wind and solar, potentially creating a total embargo on the energy sources at any utility scale. The legislation mirrors a generic bill promoted to states by the American Legislative Exchange Council, a right-wing policy shop.

China’s carbon dioxide emissions fell by 1% in the last three months of 2025, amounting to a 0.3% drop for the full year. That’s according to a new analysis by Carbon Brief. The decline extends the “flat or falling” trend in China’s emissions that started in March 2024 and has now lasted nearly two years. Emissions from fossil fuels actually increased by 0.1%, but pollution from cement plunged 7%. While the grid remains heavily reliant on coal, solar output soared by 43% last year compared to 2024. Wind grew by 14% and nuclear by 8%. All of that allowed coal generation to fall by 1.9%.
At least one sector saw a spike in emissions: Chemicals, which saw emissions grow 12%. Most experts interviewed in Heatmap’s Insiders Survey said they viewed China has a climate “hero” for its emissions cuts. But an overhaul to the country’s electricity markets yielded a decline in solar growth last year that’s expected to stretch into this year.

Rivian Automotive’s shares surged nearly 15% in after-hours trading Thursday when the electric automaker announced earnings that beat Wall Street’s expectations. While it cautioned that it would continue losing money ahead of the launch of its next-generation R2 mid-size SUV, the company said it would deliver 62,000 to 67,000 vehicles in 2026, up 47% to 59% compared with 2025. Rivian CEO RJ Scaringe told CNBC that the R2 would make up the “majority of the volume” of the business by the end of next year. He told investors 2025 was a “foundational year” for the company, but that 2026 would be “an inflection point.”
Another clean energy company is now hot on the stock market. SOLV Energy, a solar and battery storage construction contractor, secured market capitalization eclipsing $6 billion in the two days since it started trading on the Nasdaq. The company, according to Latitude Media, is “the first pure-play solar and storage” company in the engineering, procurement, and construction sector of the industry to go public since 2008.

Israel has never confirmed that it has nuclear weapons, but it’s widely believed to have completed its first operating warhead in the 1960s. Rather than give up its strategic ambiguity over its arsenal, Israel instead forfeited the development of civilian nuclear energy, which would have required opening up its weapons program to the scrutiny of regulators at the United Nations’ International Atomic Energy Agency. That apparently won’t stop the U.S. from building a reactor in Israel to power a joint industrial complex. Washington plans to develop a campus with an advanced microchip factory and data centers that would be powered by a small modular reactor, NucNet reported. So-called SMRs have yet to be built at a commercial scale anywhere in the world. But the U.S. government is betting that smaller, less powerful reactors purchased in packs can bring down the cost of building nuclear plants and appeal to fearful skeptics as a novel spin on the older technology.
In reality, SMRs are based on a range of designs, some of which closely mirror traditional, large-scale reactors but for the power output, and a growing chorus of critics say the economies of scale are needed to make nuclear projects pencil out. But the true value of SMRs is for off-grid power. As I wrote last week for Heatmap, if the U.S. government wants it for some national security concern, the price doesn’t matter as much.
Of all the fusion companies racing to build the first power plant, Helion’s promise of commercial electricity before the end of the decade has raised eyebrows for its ambition. But the company has hit a milestone. On Friday morning, Helion’s Polaris prototype became the first privately developed fusion reactor to use a deuterium-tritium fuel source. The machine also set a record with plasma temperatures 150 million degrees Celsius, smashing its own previous record of 100 million degrees with an earlier iteration of Helion’s reactor.
