After a decade of leadership, voters are poised to overturn two of its biggest achievements. What happened?

Twenty years ago, you could still get away with calling Redmond, Washington, an equestrian town. White fences parceled off ranches and hobby farms where horses grazed under dripping evergreen trees; you could buy live chicks, alfalfa, and Stetson hats in stores downtown. It wasn’t even unusual for Redmond voters to send Republicans to represent their zip code in the state legislature, despite the city being located in blue King County.
The Redmond of today, on the other hand, looks far more like what you’d expect from an affluent (and now staunchly progressive) suburb of Seattle. A cannabis dispensary with a pride flag and a “Black Lives Matter” sign in the window has replaced Work and Western Wear, and the new high-performing magnet school happens to share a name with one of the most popular cars in the neighborhood: Tesla. But Washington is a state full of contradictions, and among Redmond’s few remaining farms is one registered under the winkingly libertarian name of “Galt Valley Ranch LLC.” It belongs to a multimillionaire who has almost single-handedly bankrolled the most significant challenge yet to Washington’s standing as a national climate leader.
Andrew Villeneuve, the founder of the Northwest Progressive Institute, a left-wing think tank also based in Redmond, told me he’s struggled to get voters to pay attention to ballot measures in the past. “I’ve had no such awareness issues this year,” he said. “Nobody’s like ‘Who’s Brian Heywood?’”
A hedge fund manager, multimillionaire, and recent California transplant, Heywood has in short order made himself the supervillain of Washington’s left. His Joker arc into politics involves fleeing the liberal dystopia of the Golden State in 2010 for the no-income-tax refuge of Washington, only to discover that Olympia was progressive, too. This year, he set out to personally “fix stupid things” in his adopted state by spending $6 million out of pocket on a signature-gathering campaign that ultimately landed four conservative initiatives on Washington’s general election ballot. (His campaign, Let’s Go Washington, is also allusively named, although Heywood told The Seattle Times that he is not a MAGA supporter.)
Two of the four ballot measures Heywood has willed before voters this November address standard small-government gripes: One would repeal the capital gains tax, and the other would allow workers to opt out of the state’s long-term care payroll tax. Others, however, will ask Washingtonians to vote directly on whether to repeal the state’s landmark cap-and-invest carbon-trading program (I-2117) or block its transition away from natural gas (I-2066).
“We’ve faced initiatives like these before,” Villeneuve told me, “but what is different is how many of them are coming at once.”
As in many Western states, it’s relatively easy for a motivated individual with means to collect the roughly 320,000 signatures needed for a petition to end up on the ballot in Washington. (Contract workers are paid up to $5 per signature, and they often descend on ferry lines, where bored motorists can be talked into putting down their names as they wait for the next boat.) But while rich activists have leveraged this system in the past — Washingtonians may remember the name Tim Eyman — the outcome of the ballot measures before voters this fall will be closely watched by other states and legislatures to gauge how directly popular bold climate progress really is.
“What happens in Washington will certainly have an impact on what happens around the rest of the country,” Leah Missik, the Washington deputy policy director at the clean energy nonprofit Climate Solutions, who also serves on the executive board of the No on 2066 campaign, told me. She added, “If these [laws] are in any way repealed or weakened, that is a sign to other states, and I think it would be incredibly damaging and incredibly unfortunate.”
Though politics in Washington have long been conservation-minded and, shall we say, crunchy (I grew up in Redmond), the state really began to stand out as a leader in progressive climate policy with Governor Jay Inslee’s election in 2013. During Inslee’s tenure, Washington committed to one of the most aggressive 100% clean energy pathways in the country, passed a wide-ranging building emissions law that RMI described as “significantly [raising] the level of ambition on what might be possible for other states,” and in 2023 enacted its landmark cap-and-invest program, called the Climate Commitment Act, which has generated over $2 billion in state revenue so far for transit projects, decarbonization initiatives, and clean air and water programs. Washington has even been credited with inspiring some of President Biden’s climate actions in office.
With Inslee, a Democrat, retiring at the end of this term, Let’s Go Washington’s campaign begins to appear designed to dismantle his legacy while proposing little in the way of alternatives. Hallie Balch, the communications director, denied this allegation in an emailed statement, telling me the initiatives “promote choice and affordability.” The cap-and-invest program, for example, “has not done what the governor said it would do,” she said, and “there are no metrics in place to track [its] success.”
Though the CCA’s cap covers about 75% of the state’s total greenhouse gas emissions, it’s true that we’re still a few years away from having a clear picture of the program’s results. (The law’s first compliance deadline for polluters isn’t until this November.) “The CCA has only been around for almost two years at this point, and so we haven’t yet seen the big emissions declines,” Emily Moore, the director of the climate and energy program at the Sightline Institute, a nonpartisan sustainability think tank that does not take an official position on initiatives, told me. “But what we are seeing,” she added, “is the money that it has generated for a whole suite of climate-friendly and community-friendly projects.”
There isn’t a revenue source remotely comparable to cap-and-invest available to fund the state’s transit, infrastructure, and community projects if the program goes away, meaning a repeal would have a dramatic impact on everything from bus service to salmon recovery projects to local heat pump and induction stove rebates, with most likely getting the axe. The program is also one of the main levers Washington has to reach its goal of reducing emissions 95% below 1990 levels by 2050. As one person involved in crafting the CCA described the upcoming vote on I-2117 to me, it’s “life or death for climate action in Washington.”
That’s partially because I-2117 wouldn’t only repeal the CCA; it would also bar the state and any municipality therein from implementing a new climate tax or cap-and-invest program at any point in the future. When asked what an alternative might be last week during a debate at Seattle University’s Department of Public Affairs and Nonprofit Leadership, Heywood vaguely proposed “something that works.”
“We always knew we were going to have to defend this program at the ballot box,” Joe Fitzgibbon, the majority leader of Washington’s House of Representatives and the chair of the House Environment and Energy Committee, who helped create the CCA, told me. He admitted that he’d expected such a defense to take the form of legislative elections, but 2022 came and went without a single backer of the CCA losing their seat. “I guess in hindsight, I thought we were out of the woods,” Fitzgibbon said.
Let’s Go Washington has labeled CCA a “hidden gas tax” and, bundled with its other initiatives, is running on the slogan “vote yes, pay less.” I-2117 is already the most expensive ballot measure campaign of this election cycle — and the most controversial, with Heywood campaigning at gas stations offering discounted gas, which opponents say violates vote-buying anti-bribery laws. But opposition to the initiative has also rallied a remarkable and unprecedented coalition of strange bedfellows in defense of the CCA, including over 500 businesses, environmental groups, health care organizations, faith leaders, tribes — as well as more than 30 breweries, “a very important coalition member in the state of Washington,” as No on I-2117’s communication director Kelsey Nyland quipped to me. Jane Fonda recently swung through the state to stump for I-2117; the ‘no’ campaign even has the support of the Green Jobs PAC, whose contributors include Shell and BP.
Almost all the advocates I spoke to about I-2117 were feeling optimistic ahead of Washington ballots going out at the end of this week, with the most recent Cascade PBS/Elway poll on the initiative showing support has dropped slightly since May; 46% now say they would vote no, over 30% who would vote yes. (Heywood has pointed optimistically to the number of undecided voters this leaves.) Still, it seems pretty unlikely that Washingtonians will repeal their cap-and-invest program.
I-2066 is a different story.
To the immense frustration of its opponents, Let’s Go Washington touts I-2066 as “Stop the Gas Ban.” The measure was only certified for the ballot in July, compared to January for 2117, meaning that organizers have had much less time to mobilize — several major national green groups, including Defenders of Wildlife and the Environmental Defense Action Fund, confirmed to me that they’d endorsed No on I-2117 but not considered a position on I-2066 — and are on the back foot to combat misinformation.
For one thing, there is no gas ban: I-2066, rather, would repeal parts of a Washington law directing its largest utility, Puget Sound Energy, to consider electrification alternatives before installing new gas pipes; scuttle a pilot effort to promote thermal energy networks as a gas alternative; and, most starkly, it would bar cities and towns, as well as Washington’s energy code, from “prohibiting, penalizing, or discouraging” gas appliances in buildings. “Discouraging” does a lot of work here. For example, Seattle’s building emissions performance standard, which doesn’t ban gas but nudges large developments toward a 2050 net-zero emissions target, could be in jeopardy.
Still, all of this is a lot to expect voters to sort through in the few minutes they might spend filling in the bubbles in their ballot, especially when Let’s Go Washington is making out its message to sound like one simply about energy choice. Add the opaque triple-negative climate campaigners have to sell (“vote no on a ban on banning gas”), and the messaging headaches grow more severe.
Earlier this month, the editorial board for the largest media outlet in Washington, The Seattle Times, endorsed a yes vote on I-2066, arguing for a slower transition away from fossil fuels that leans more heavily on natural gas. “Unfortunately, we are up against a network of fossil fuel corporations and their allies who have a lot of money and who are very invested in the status quo because it perpetuates their wealth and their influence,” Missik, who’s involved with the No on I-2066 campaign, told me, pointing to the Building Industry Association as well as Northwest Natural, National Propane Gas Association, and Koch Industries, who have backed the other side. I-2066 is also polling much better than I-2117; as of September, 47% of voters said they would vote yes, compared to 29% who said they’d vote no.
Rather than interpret those numbers as the electorate’s backlash to Washington’s climate progress, advocates argue they indicate how fossil fuel groups have successfully capitalized on the door propped open by Heywoods’s signature-gathering campaigns. It’s “because one guy opened his wallet; it is that simple,” Villeneuve, the founder of the Northwest Progressive Institute, said. “There is no grassroots movement to overturn these laws; it doesn’t exist. Brian Heywood brought this entire thing into being.” Or, as Missik put it: “Most Washingtons do believe in climate progress, whether or not this will be overridden by money. I sure hope not.”
All of this ultimately brings us back to the question of what Heywood’s whole deal is. With the singular exception of I-2066, his $6 million initiatives seem mostly doomed.
Some I spoke to floated the idea that Heywood and his allies are using Washington as a testing ground for dismantling climate action and seeing what sticks. “If it can happen here, it can happen anywhere: It can happen in California, it can happen in Colorado, it can happen in New York, it can happen in all these states that have passed really strong climate policies,” Caitlin Krenn, the climate and clean energy director of the nonprofit Washington Conservation Action, told me.
But there are other rumors, too. The Washington State Standard’s Jerry Cornfield recently quoted a local GOP chair calling Heywood’s initiatives “a powerful tool” that will “help get Republicans elected” — essentially, a turnout generator. (“We certainly want to see as many people as are eligible to vote exercise their right to make their voices heard, but our top priority is to educate voters about what's at stake with the initiatives this November,” Balch told me in response.) And then there is Heywood’s ranch. Republicans have long cosplayed as rural farmers and cowboys to tap into the masculine conservative fantasy of rugged individualism (what Texas Monthly once called “authenticity drag”). It’s essentially an image-building exercise — perhaps not so unlike positioning yourself as the guy who tried to rein in the state’s runaway Dems.
So far, Heywood has dodged questions about whether he plans to run for governor, and his campaign told me he “isn't using the initiatives as anything other than a way to bring broken policies directly to the people to vote on.” But with this year’s ballots going out to Washington voters today, it’s also a question for another time.
Regardless of what happens, many of the organizers I spoke to rejected the framing of Washington voters cooling on climate. One went as far as to tell me that the time, attention, and money Heywood has spent trying to roll back Washington’s progress is the highest compliment of all. “This is part of the process of doing big things,” Isaac Kastama, who was involved in enacting the CCA and now works for the advocacy group Clean and Prosperous Washington, told me. “If it’s not big and if it goes undetected, that probably means you’re not doing something serious enough.”
Editor’s note: This story has been updated to clarify the scope of I-2117 and correct what Let’s Go Washington has termed a “hidden gas tax.”

The enhanced geothermal company just announced a new 19,448-foot well.
Enhanced geothermal company Fervo has drilled another well.
This one is 19,448 feet deep, the company announced Thursday, and includes a 7,500-foot span laterally across the sub-surface. The well — called Sawtooth 7, part of Phase II of its flagship Cape Station project in Milford, Utah — took 21 days to drill, the company said. That matches the time required to drill the wells in Phase I, though the new one is nearly 35% deeper than those, on average, with a 50% greater lateral extension.
The greater depth and distance means greater energy potential from the well, while faster drilling times mean much lower costs. Tim Latimer, Fervo’s co-founder and chief executive, compared the timeline to that of the company’s 2022 Project Red well in Nevada, which achieved a depth of 11,220 feet in 70 days.
“Today, we are drilling deeper, hotter wells that will produce multiples more [megawatts] per well than our Project Red pilot, and we are doing it in a fraction of the time,” Latimer wrote.
Fervo says that its drilling rates at the Cape Station site have improved by 143% since it broke ground there in 2023.
The company says it’s now on track to get project costs down to $5,500 per kilowatt, working toward a goal of $3,000 per kilowatt over the long term. In its IPO filing, Fervo said costs at Cape Station were around $7,000 per kilowatt, indicating significant improvements in drilling efficiency in a relatively short period of time.
The news should be welcome to Fervo and its investors. Shortly after going public in May, the company announced that one of its Utah wells blew out. The company said at the time that there were no injuries, nor was there any environmental damage or “material impact to either cost or schedule of the project” at Cape Station.
Fervo raised almost $2 billion in its IPO, which it said will go to fund further progress on the flagship installation. Shares were trading at around $26 on Thursday afternoon, just shy of their $27 IPO price and up over 13% on the day.
The Earth Fire Alliance is aiming for a constellation of high-resolution sensors that can capture the whole globe every 20 minutes.
Wildfires burn tens of millions of acres worldwide every year, and they’re only becoming more destructive.
For the past few decades, satellites operated by the likes of NASA and NOAA have assisted fire crews in detecting and tracking wildfires in even the most remote, difficult-to-monitor landscapes. But helpful as they are, these systems can’t provide real-time, actionable insights. They typically can’t spot fires until they’ve grown to several acres, for instance. They also only provide an image of the same spot every 12 hours at best, and by the time the data reaches the ground, hours — sometimes days — may have passed.
But the nonprofit Earth Fire Alliance says it’s built a far more capable alternative. In the wee hours of Tuesday morning, it launched three minifridge-sized satellites into orbit, the first components of a purpose-built wildfire detection constellation of more than 50 satellites planned to be fully operational by the 2030s. Designed to detect much smaller blazes than existing systems, the network will give first responders earlier warning and more time to contain fires before they spread. FireSat will also provide the broader scientific community with new data on how and why smaller burns grow into destructive wildfires, helping to improve models of fire behavior amidst a changing climate.
“We’ll be able to see fires as small as five by five meters — that’s the size of a shipping container — and be able to see fires at a lower temperature than a lot of the other satellite systems do,” Karen O’Connor, a founding principal at Earth Fire Alliance, told me. Once the full constellation is in orbit, the goal is to use the satellite’s thermal imaging capabilities to provide updates on fires every 20 minutes. “When you think about how that compares with current systems, they might see two to three acres. They might be over the same region maybe once or twice a day,” O’Connor explained.
The initiative has raised $69 million from a coalition of philanthropic backers, including a $26 million grant from the Bezos Earth Fund, over $15 million from Google.org, and support from the Gordon and Betty Moore Foundation, as well as other donors. The alliance’s technical partner, Silicon Valley startup Muon Space, designed and built the satellites. The company validated its tech last March when it launched a prototype satellite into orbit that detected a small fire in Oregon that existing systems missed.
O’Connor told me the team has interviewed hundreds of firefighters, fire agency officials, and fire scientists since the project kicked off six years ago, so that they could design the system to meet their needs. Those features include ultra-high-resolution sensors and an unusually wide field of view — over 930 miles across. Each satellite can quickly scan vast swaths of land, imaging the entire globe in about 12 hours. With more satellites will come greater imaging frequency: The alliance aims to capture an image of any point on Earth at least once an hour by 2029, reaching every 20 minutes by the early 2030s.
Hourly imaging “gets us within operational decision making timeframes,” O’Connor told me. Many fire agencies already receive intelligence updates from weather monitoring stations on this cadence, meaning at this point FireSat data can fit directly into their existing workflows to inform decisions about if, where, and when to deploy crews.
FireSat also provides a much clearer, more detailed view of active fires than standard Earth observation satellites, whose imagery generally lacks the resolution needed to manage fires in real time. Its specialized sensor captures six distinct bands of light — one visible, one near infrared, and four thermal infrared bands — each revealing different characteristics of the fire and its progression.
Visible light provides a baseline view of the landscape, while near infrared wavelengths reveal how vegetation responds to a fire — a stronger near-infrared signal indicates healthy vegetation. Short-wave infrared allows satellites to see through smoke during active fires and identify the areas burning with the most intensity. Mid-wave infrared is FireSat’s most unique and valuable channel for fire detection. Unlike most systems which use a single mid-wave band, FireSat uses two. One is attenuated — essentially tuned down — to allow the sensor to measure extremely hot fires without its gradations becoming saturated. The other is not, allowing the satellite to pick up smaller, lower-intensity blazes.
Long-wave infrared helps detect cooler parts of a fire as well as the temperature of the surrounding landscape, including smoldering areas, burn scars, and changes in ground temperature. This helps researchers better distinguish fire signatures and understand their impacts on smoke and air quality.
The three newly launched satellites will now undergo about three months of testing and calibration before they begin feeding data directly to FireSat’s early adopters, which include Cal Fire in California as well as fire agencies in Colorado, Oregon, Texas, Africa, Australia and Portugal.
“We’ve started with the operational community because we think that they’re the ones that need to be using the data from the beginning,” O’Connor told me. But as FireSat’s data set grows and researchers build a more exact historical record of recent fires, the patterns that emerge should provide valuable scientific insights such as seasonal shifts in fire behavior, how fires spread across different environments, and their impacts on ecosystems, biodiversity, and emissions.
Fire modeling is already evolving quickly these days, as startups and research labs increasingly integrate AI into their wildfire simulation models and risk assessments. Examples include companies like Pano AI and Technosylva, as well as researchers at the USC Viterbi School of Engineering and the University of Buffalo. O’Connor told me she thinks FireSat’s data will help further improve these models. “By having a real-time, regularly updated fire path, they can actually go back in and train those tools again — like this is how the fire actually behaved — so that in the future those types of tools will be better for the operational decision makers.”
FireSat could also help reveal the true global scale of fire activity. Until recently, existing systems couldn’t reliably detect smaller conflagrations, so the historical record has mostly captured only the largest ones. A more complete picture of fire activity will improve carbon emissions accounting and inform better land management practices.
That said, it remains true that not every fire ought to be put out. Fire is a natural — and often essential — ecological cycle that helps landscapes like grasslands, chaparral, and forests stay healthy while clearing dead vegetation that would otherwise accumulate as fuel for more destructive wildfires. O’Connor expects FireSat to play a role here, as well, giving agencies a better way to monitor prescribed burns and naturally occurring fires alike to ensure they deliver their ecological benefits without getting out of hand.
Even so, there are limits to what better detection and more sophisticated modeling can achieve when it comes to reducing the toll of wildfires. As the deadly Los Angeles fires at the beginning of 2025 demonstrated, even blazes caught in their earliest stages can explode under a dangerous combination of high winds and drought — conditions that are becoming increasingly common with climate change. Furthermore, as people continue to build homes and infrastructure along the wildland-urban interface, there are limits to how much technology can protect developments in landscapes that are naturally adapted to burn.
Still, FireSat’s data stands to make a meaningful difference in our ability to respond to an increasingly fire-prone world, though those benefits won’t arrive overnight, of course. These first three satellites will offer an early glimpse of what FireSat can deliver at scale, with the real value of the constellation beginning to emerge by the end of the decade. “Four of the five biggest wildfire years were in the 2020s,” O’Connor told me. “We can’t afford to go any slower than that.”
On Trump’s mineral paradox, China’s Great Green Wall, and sodium-ion batteries
Current conditions: After devastating the U.S. island of Rota in the Northern Mariana Islands territory, Super Typhoon Bavi is barreling toward Taiwan with winds of up to 200 miles per hour • Rare tornadoes brought on by storms touched down in China’s Hubei province, leaving 11 dead • Temperatures in Madrid are hovering at around 100 degrees Fahrenheit all week as the Spanish capital roasts in Europe’s latest heat wave.
Exactly three weeks after President Donald Trump signed a formal memorandum to halt the bombing campaign against Iran that the United States and Israel embarked on nearly five months ago, the war is back on. After Washington accused Tehran of launching missiles at tankers passing through the Strait of Hormuz this week, Trump officially declared the resumption of combat. Speaking Wednesday morning at the NATO summit in Turkey, Trump called the Iranian regime “scum,” “sick people,” and “vicious, violent people” when asked about the peace pact during a press conference. “If they had a nuclear weapon, they’d use it,” Trump said. “So as far as I’m concerned, it’s over.” He spent the rest of the day posting more than a dozen videos and photos on his Truth Social account purportedly showing U.S. missile strikes in Iran. “This is in retribution for yesterday’s bombing of ships by Iran,” Trump wrote in one post. “If it happens again, it will get much worse!”
The market is certainly preparing for worse. The price of Murban crude, the benchmark for oil flowing out of the United Arab Emirates, spiked nearly 7% on Wednesday. The European benchmark, Brent crude, jumped more than 5%. The American pricing yardstick, West Texas Intermediate crude, rose by just over 1%. Last month, my colleague Matthew Zeitlin cautioned that, despite a ceasefire, it would take a while for the Strait of Hormuz to return to normal — and “even longer” for energy markets. Emphasis on that last part.
The world’s capacity to generate nuclear energy has increased by 2.2 gigawatts already this year as new Chinese reactors have come online at a rapid clip. By 2035, global nuclear capacity is on track to surge by 44% to 535 gigawatts, up from 372 gigawatts last year. That’s according to the latest forecast from the consultancy BloombergNEF. China, the unrivaled global leader in domestic reactor construction, is largely responsible for the projected spike. Today, the People’s Republic is the world’s No. 2 user of atomic energy behind the U.S., which has long operated the largest fleet of plants on the planet. But China is on pace to surpass the U.S. by 2030 with 102 gigawatts of nuclear capacity.
Among the more promising signs for the democratic world: The U.S. is now working with Japan and South Korea to commercialize new small modular reactor technologies. On Tuesday, at the margins of the NATO summit, U.S. Secretary of State Marco Rubio signed onto a memorandum with the foreign ministers of Japan and South Korea. The document “outlines opportunities for our three countries, which have complementary advantages in the civil nuclear field, to encourage mutually beneficial cooperation among their respective nuclear industries,” the State Department said in a statement.
Right after the presidential inauguration in January 2025, Matthew wrote a sharp piece identifying what he called the “paradox of Trump’s critical minerals crusade.” At issue was the fact that the new Trump administration planned to (and ultimately did) kill off policies designed to spur demand for domestically mined and processed minerals such as lithium, cobalt, and rare earths — even as he slashed barriers to increasing the supply of those metals. U.S. production of minerals is picking up as the White House brokers a growing list of deals to give the government equity stakes in mining firms in exchange for federal support for increasing output. Sure enough, the demand just isn’t there in the U.S. On Tuesday, the Financial Times reported that companies backed by the administration, including rare earths miner MP Materials, uranium producer Energy Fuels, and the rare earths refiner Phoenix Tailings are instead selling their goods to buyers in Asia. Japanese customers were “clamoring” for rare earth metals from Phoenix Tailings, CEO Nick Myers said. The materials the firm produces are ending up “primarily in Korea and Japan.”
That isn’t stopping Trump from reviving his calls for Washington to seize Greenland and its resources from Denmark, a founding NATO ally. Speaking at the conference in the Turkish capital of Ankara, the American president repeated his claim that the U.S. invasion of the world’s largest island following Copenhagen’s collapse to Nazi blitzkrieg in April 1940 should have qualified as a permanent conquest. “We took Greenland and then, stupidly, we gave it back,” Trump told reporters. “We shouldn’t have given it back to them. We’re the ones who need it. We need it for protection of the world, not just the United States.”

Not to be an old man about it, but I remember the Iraq War distinctly — the debates over the role of Baghdad’s oil and the calls from Congress for increased U.S. production with an eye toward energy independence. Here’s some data that will make you want to dismiss your humble millennial correspondent with an “ok boomer.” On Wednesday, the U.S. Energy Information Administration issued a definitive new analysis showing that U.S. petroleum exports hit a record high in April after Iran closed the Strait of Hormuz, forcing overseas buyers to find new sources of fuel. Exports increased to 13.6 million barrels per day, 15% more than the previous record set in March.
On the other end of the American energy spectrum, the nation’s largest provider of home battery and solar equipment just launched a distributed compute pilot program for artificial intelligence servers. Under the program, Sunrun will coordinate “the selling of inference capacity to enterprise compute buyers.” In other words, homeowners can earn money by hosting “compute nodes” — small servers —that then supply output to AI companies in much the same way Sunrun’s customers are paid by giving the virtual power plant operators access to solar panels and batteries. “Over nearly two decades, we have perfected our ability to operationalize, finance, and scale distributed assets,” Paul Dickson, Sunrun’s president and chief revenue officer, said in a press release. “We are now using our leadership position in distributed home energy and proven infrastructure to bring compute closer to the sources of energy and inference.”
Much like the United Nations effort to plant trees at the southern edge of the Sahara to keep the desert at bay, China is building a Great Green Wall. Since 1978, the country has planted 66 billion trees and plans another 34 billion by 2050 in a bid to slow the spread of the Gobi and Taklamakan deserts. A new study using satellite measurements of leafy areas found that the planted forests are greening much faster than wild ones. Younger trees grow faster. But even at similar ages, planted stands grew 4.6% faster, meaning they can absorb more carbon. The findings, according to Fertilizer Daily, “suggest global climate models should better distinguish forest types and age when accounting for carbon.”
Sodium-ion technology, as Heatmap’s Katie Brigham explained two years ago, promises cheaper, less combustible batteries than its dominant lithium-ion cousin. But it remains niche and underdeveloped. Perhaps not for long. On Wednesday, sodium battery startup Peak Energy announced plans for a factory in Sacramento capable of producing 4 gigawatt-hours of sodium battery systems annually. “America needs energy storage that is lower cost, more affordable, more reliable and purpose-built to meet the demand coming onto the grid,” Peak Energy CEO Landon Mossburg said in a statement. “This facility is proof that America can lead not only in inventing the technology, but in building it at scale.”
