From the national to the state to the local level, the state is about to hold some of the country’s most crucial elections.

In 2022, the Arizona Republic published a sentence many Democrats had dreamed of reading for decades: “Arizona,” the paper announced, “is a blue state.”
At the time, it felt true. In 2020, Joe Biden won the Grand Canyon State — only the second time a Democrat had done so since Arizona broke for Harry Truman in 1952 — and Democrat Mark Kelly defeated Republican Sen. Martha McSally in a special election to fill the late John McCain’s Senate seat, a victory that helped the Inflation Reduction Act get over the finish line. The 2022 midterm elections confirmed that the Democrats’ wins in the state hadn’t just been a one-time occurrence: Kelly successfully defended his seat, securing a full term; Katie Hobbs won the governorship; and Adrian Fontes beat a January 6 participant to become the secretary of state, Democrats all.
With the 2024 election still a little more than a week away, it’s too soon to tell whether the blue state proclamations of 2022 were premature. But Arizona hasn’t been looking terribly cerulean. In 2023, the Republican-held state legislature passed eight of 16 anti-environment bills introduced and stranded 22 pro-environment bills without committee hearings. Republican voter registration in the state has also swelled since 2016 as Democratic rolls stayed relatively stagnant, giving the GOP an edge in a place where 10,457 votes can make all the difference.
Arizona is just one state out of 50 (or 11 electoral votes out of 538, if you prefer), but it represents a curious microcosm of the high-stakes climate and energy elections happening all over the country this November. Or perhaps it is not so curious: Arizona is on the front lines of the climate-related impacts of droughts, longer and nastier heat waves, ozone pollution, and wildfires, while also being in a position to weigh the trade-offs of crucial clean energy developments like building new energy transmission, critical mineral mining, and utility-scale solar. “It’s like an incubator. There’s just so much happening here, it’s ready to burst,” Jane Conlin, a co-leader of the Tucson chapter of the Citizens' Climate Lobby, which has been engaging in get-out-the-vote efforts with the Environmental Voter Project, told me.
Aside from its electoral college allocations, the most consequential race in Arizona this cycle will be for outgoing Independent Senator Kyrsten Sinema’s seat. The state is currently leaning slightly toward Democratic Representative Ruben Gallego, who could help stem a total hemorrhaging of blue seats from the Senate — which, in turn, would have implications for the passage of any decarbonization legislation in the next administration.
Two U.S. House elections in Arizona could similarly help determine the balance of power on Capitol Hill come January. AZ-01 is the wealthiest congressional district in the state, in the northeastern corner of Phoenix’s Maricopa County, where a former E.R. doctor is trying to unseat a seven-term Republican incumbent in a battle that has centered on abortion access. (The district is also home to the Rio Verde Foothills, which made national headlines in 2022 when Scottsdale cut off its water supply due to drought-related shortages.)
But it’s the other race, in the sixth congressional district spanning the suburbs of Tucson, that looks more like a proxy battle between different climate ideologies. Kirsten Engel — who previously worked for the U.S. Environmental Protection Agency and serves as the co-director of the Environmental Law Program at the University of Arizona — is challenging Juan Ciscomani, a Trump-endorsed moderate conservative who has backed residential solar projects, promoted himself as an advocate for a “secure water future,”and, earlier this year, co-sponsored a bill seen as a first step toward a carbon border tax. (As his opponents quickly point out, he also voted against the IRA; Ciscomani has also been tied to a groundwater scandal involving a Saudi Arabian-owned alfalfa farm.)
Engel previously lost a tight election against Ciscomani in 2022, and has made abortion a centerpiece of her campaign, too. But she has also gone aggressively after the Republican for his alignment with the mining industry, including his support for a proposed open-pit copper mine that opponents say will pollute Tucson’s air and waterways; supporters, meanwhile, say it’s critical to create a domestic supply chain for the energy transition. The League of Conservation Voters, which identified the sixth congressional district election as one of its priority races, is running ads in the state playing up this pollution angle.
Engel herself has slammed the proposed mine, which would be built on public lands, as a “giveaway” to a foreign mining company, and touted the need to protect the region’s “spectacular scenic vistas and the tourism economy.” She has also sought to go toe-to-toe with Ciscomani on water conservation, though as Grist has reported, drought and water rights can be tricky for Arizona politicians to run on because voters don’t have a firm grasp of how the complicated policies work.
The future of climate policy at the regional and municipal levels in Arizona is also in play. Democrats could potentially flip the balance of power in the state House and Senate, each branch currently having just a one-seat Republican advantage, and restart movement on the slate of stalled pro-environmental bills. (The Democratic governor’s term runs through 2026.) “The state legislature in Arizona is so critical,” John Qua, the campaign manager of Lead Locally, told me. “Not only does building a democratic trifecta get the state closer to passing policy that tackles climate change in some of the ways we might more typically understand it — like moving towards clean energy — but it also makes it much likelier that the state legislature will pass water conservation policy.”
The 11 races are “all at a razor-thin margin,” Qua told me, though climate is unlikely to be the issue that tips the balance in any of them. That goes for just about any race in Arizona — except the state’s Corporation Commission, which Heatmap’s Emily Pontecorvo covered earlier this week. Currently, the ACC is operating with a four-to-one Republican majority, but with three Democrats, two Green party candidates, and three Republicans (including an incumbent) running to fill three seats, there’s a wide-open chance that candidates sympathetic to clean energy policy, including the state’s massive solar opportunity, could take control.
“Arizona could lead the world in solar power if politicians would only let it,” Nathaniel Stinnett, the founder and executive director of the Environmental Voter Project, told me. “But that isn’t going to happen unless the climate movement starts showing up in unstoppable numbers whenever there’s an election.”
Conlin, who co-leads the Tucson chapter of the Citizens’ Climate Lobby, has been working on the ground to reach the 230,000 potential first-time environmental voters that Stinnett and his team have identified in the state. (EVP numbers released earlier this week showed that those who vote based on climate issues were about 20% more likely to have submitted an early vote than the average voter.) During a recent folklife festival CCL volunteers attended, “I think about only 25% of people [we engaged with] were really aware of the Arizona Corporation Commission,” Conlin told me. But she’s excited nevertheless: This year, the ACC poll is on the front of Arizonans’ ballots, rather than the back, making it harder for even low-information voters to overlook.
The state is also a case study of how an elected body as small and seemingly insignificant as a school board can make a difference in the progress toward decarbonization. The Tucson Unified School District board of governors will vote next week on a climate action plan that would set a goal of reaching net-zero emissions by 2045. If successful, TUSD would be one of the first school districts in the nation to have implemented such a plan.
Arizona is not the only state in the country that, as Colin put it, feels “on this cusp of being able to reach out — not only to see a 50% cut in emissions but 100%. It’s doable, it’s within reach.” Pennsylvania and Michigan voters will also have opportunities to elect politicians who will advance climate legislation, and voters in Washington, California, and New York can defend their states’ progress. But it’s Arizona where the stakes seem especially immediate — and high. “It’s supposed to be 96 [degrees Fahrenheit] here today,” Conlin marveled when we spoke this week, at the end of October.
I could hear the weariness in the voices of the organizers I spoke to after a long, hard-fought season; candidates are set to make their final pitches to voters next week. Early-voting ballots are already in the mail or in hand. The CCL has just one final day of canvassing planned, on November 2. The polls will close three days later, at 7 p.m. local time, and then the count will begin.

Topsy turvy oil prices aren’t great for the U.S.
Oil prices are all over the place as markets reopened this week, climbing as high as $120 a barrel before crashing to around $85 after Donald Trump told CBS News that the war with Iran “is very complete, pretty much,” and that he was “thinking about taking it over,” referring to the Strait of Hormuz, the artery through which about a third of the world’s traded oil flows.
Even $85 is substantially higher than the $57 per barrel price from the end of last year. At that point, forecasters from both the public and the private sectors were expecting oil to stick around $60 a barrel through 2026.
Of course, crude oil itself is not something any consumer buys — but those high prices would likely feed through to higher consumer prices throughout the U.S. economy. That includes the price of gasoline, of course, which has risen by about $0.50 a gallon in the past month, according to AAA, — and jet fuel, which will mean increased travel costs. “Book your airfares now if they haven’t moved already,” Skanda Amarnath, the executive director of the economic policy think tank Employ America, told me.
High oil prices also raise the price of goods and services not directly linked to oil prices — groceries, for instance. “The cost of food, especially at the grocery store, is a function of the cost of diesel,” which fuels the trucks that get food to shelves, Amarnath told me. Diesel prices have risen even more than gasoline in the past week, by over $0.85 a gallon.
“We’ll see how long these prices stay elevated, how they feed their way through the supply chain and the value chain. But it’s clearly the case that it is a pretty adverse situation for both businesses and consumers.”
The oil market is going through one of the largest physical shocks in its modern history. Bloomberg’s Javier Blas estimates that of the 15 million barrels per day that regularly flow through the Strait of Hormuz, only about a third is getting through to the global market, whether through the strait itself or by alternative routes, such as the pipeline from Saudi Arabia’s eastern oil fields to the Red Sea.
Global daily oil production is just above 100 million barrels per day, meaning that around 10% of the oil supply on the market is stuck behind an effective blockade.
“The world is suddenly ‘short’ a volume that, in normal times, would dwarf almost any supply/demand imbalance we debate,” Morgan Stanley oil analyst Martjin Rats wrote in a note to clients on Sunday.
The fact that the U.S. is itself a leading producer and exporter of oil will only provide so much relief. Private sector economists have estimated that every $10 increase in the price of oil reduces economic growth somewhere between 0.1 and 0.2 percentage points.
“Petroleum product prices here in the U.S. tend to reflect global market conditions, so the price at the pump for gasoline and diesel reflect what’s going on with global prices,” Ben Cahill, a senior associate at the Center for Strategic and International Studies, told me. “What happens in the rest of the world still has a deep impact on U.S. energy prices.”
To the extent the U.S. economy benefits from its export capacity, the effects are likely localized to areas where oil production and export takes place, such as Texas and Louisiana. For the economy as a whole, higher oil prices will improve the “terms of trade,” essentially a measure of the value of imports a certain quantity of exports can “buy,” Ryan Cummings, chief of staff at Stanford Institute for Economic Policymaking, told me.
Could the U.S. oil industry ramp up production to capture those high prices and induce some relief?
Oil industry analysts, Heatmap founding executive editor Robinson Meyer, and the TV show Landman have all theorized that there is a “goldilocks” range of oil prices that are high enough to encourage exploration and production but not so high as to take out the economy as a whole. This range starts at around $60 or $70 on the low end and tops out at around $90 or $95. Above that, the economic damage from high prices would likely outweigh any benefit to drillers from expanded production.
And that’s if production were to expand at all.
“Capital discipline” has been the watchword of the U.S. oil and gas industry for years since the shale boom, meaning drillers are unlikely to chase price spikes by ramping up production heedlessly, CSIS’ Ben Cahill told me. “I think they’ll be quite cautious about doing that,” he said.
A test drive provided tantalizing evidence that a great, cheap EV is possible for the U.S.
Midway through the tortuous test drive over the mountains to Malibu, as the new Chevrolet Bolt EV ably zipped through a series of sharp canyon corners, I couldn’t help but think: Who would want to kill this car?
Such is life for the Bolt. Chevy revived the budget electric car after its fans howled when it killed the first version in 2023. But by the time the car press assembled last week for the official test drive of Bolt 2.0, the new car already had an expiration date: General Motors said it would end the production run next summer. This is a shame for a variety of reasons. Among the most important: The new Bolt, which starts just under $30,000 and is soon to start arriving at Chevy dealerships, shows that the cheap EV for the masses is really, almost there.
The 2027 Bolt comes with a 65 kilowatt-hour lithium iron phosphate battery that’s rated to deliver 262 miles of range. That’s not bad for an economy car, given that lots of more expensive EVs came with ranges in the low 200s just a couple of years ago.
Charging speed, the big bugaboo with the original Bolt, is fixed. The glacial 50-kilowatt speed has risen to 150 kilowatts, allowing the car to charge from 10% to 80% in about 25 minutes. That pales in comparison to the 350-kilowatt Hyundai touts for some of its EVs, but it makes the Bolt road trip an acceptable experience, not a slog. Crucially, the new Bolt comes with the NACS port and will seamlessly plug-and-charge at many charging stations, including Tesla’s.
Bolt comes with a single motor that delivers 210 horsepower and 169 pound-feet of torque — not eye-popping numbers. But because all of an electric car’s torque is available at any time, the Bolt feels livelier as it accelerates away from a start compared to an equivalent combustion-powered economy car. It huffs and puffs just a tad trying to accelerate uphill on California’s mountain highways, sure, but Bolt has enough oomph to have some fun without getting you into trouble. And in a world of white cars, Bolt comes in honest-to-goodness colors. Red. Blue. Yellow!
The tech features are the same story — that is, plenty good for the price. Many Bolt loyalists are incensed that Chevy killed off Apple Carplay and Android Auto integration in the new car, forcing drivers to rely on what’s built in. For those who can get over the disappointment, what is built into Bolt’s 11-inch touchscreen is pretty good, starting with Google Maps integration for navigation. Its method for displaying charging stations — and allowing the driver to filter them by plug style, provider, and other factors — isn’t quite up to the Silicon Valley seamlessness of a Rivian, but is easier to use than what a lot of legacy car companies put in their EVs. (The fabulous Kia EV9 three-row SUV I tested just before the Bolt is superior in just about every way except this.)
The Bolt even has a few features you wouldn’t expect at the entry level. The surround vision recorder for storing footage from the car’s camera is a first for a GM vehicle, Chevy says. The brand is also making a big to-do over the Super Cruise hands-free driving feature since the Bolt is now the least expensive car to get it, though adding all that tech takes the basic LT version of the Bolt up from $29,000 to more than $35,000, which is the starting price for the bigger Chevy Equinox EV.
With so much going right for this vehicle, why preemptively kill it? The most obvious factor is the Trump White House. Chevrolet had always called the Bolt’s return a limited run, but the fact that its production run might last for just a year and a half is a direct result of Trump tariffs: GM wants to make gas-powered Buick crossovers, currently made in China, at the Kansas factory that builds the Bolt.
And the loss last year of the federal incentive to buy an EV is particularly punitive for the Bolt. With $7,500 shaved off the price, the Chevy EV would have been cost-competitive with the cheapest new gas cars, like the Hyundai Elantra or Toyota Corolla. Without it, Bolt is closer in price to a larger vehicle like the Toyota RAV4. When Chevy can’t make the case that its EV is as cheap as any other small car you might be looking at, it must sell a car like Bolt on its down-the-road value: very little routine maintenance, no buying gasoline during a period of wartime oil shocks, and so on. That’s a tougher task, and perhaps explains why GM was so quick to move on.
Still, there’s clearly something bigger at stake here for GM. The American car companies’ pivot back to the short-term profitability of petroleum, exemplified by the Bolt-Buick affair, comes as the rest of the world continues to embrace EVs. Headlines lately have wondered whether China’s ascent combined with America’s yoyo-ing on electric power could lead to Detroit’s outright demise, leaving the U.S. auto industry with scraps as someone else’s superior EVs take over the world.
In this light, Chevy’s own market data on Bolt is especially jarring. Of the nearly 200,000 Bolts on the road from the car’s previous generation, 75% percent of those drivers came from other car companies to GM, and 72% remained loyal to GM. In other words, the new Bolt is set to build on General Motors’ status as the top EV-seller in America behind Tesla by expanding the established base of customers who love Chevy electric cars. That is what’s being tossed aside to increase quarterly profits.
Maybe the Bolt will surprise its maker, again. Even if a groundswell of enthusiasm for the new car isn’t enough to save it from extinction, perhaps it will prove to GM to give the budget EV yet another go-around when the market shifts yet again.
Current conditions: Spring-like temperatures have arrived in New York City, with a high of 62 degrees Fahrenheit today • The death toll from the flooding in Nairobi, Kenya, has risen to at least 42 • Heavy rain in Peru threatens landslides amid what’s already been a deadly wet season.
It only took a week. But, as I told you might happen sooner than later, oil prices surged past $100 per barrel for the first time since 2022 as the war against Iran continues. The latest hit to the global market came when Kuwait and the United Arab Emirates started cutting production over the weekend at key oil fields as shipments through the Strait of Hormuz ground to a halt. In a post on his Truth Social network, President Donald Trump said prices “will drop rapidly when the destruction of the Iran nuclear threat is over,” calling the rise “a very small price to pay for U.S.A.” In response, oil analyst Rory Johnston said Trump’s statement would only spur on the market craziness. “No one who has any idea how the oil market works is buying it — all this does is make it seem like Trump believes it, which means the base case length of this disruption is growing ever-longer,” he wrote. “Tick. Tock.”
The war’s effect on energy markets isn’t just an oil story. As Heatmap’s Matthew Zeitlin wrote, it’s also a natural gas story. Similarly, as Matthew wrote last week, the winners of the market chaos run the gamut from coal to solar panels.

The numbers are in. Last year, the United States generated 4,430 terawatt-hours of electricity. That’s up 2.8% from 2024, which previously had been the highest annual total in the Energy Information Administration’s record books, which date back to 1949. Residential electricity sales grew 2.2%, while commercial surged by 2.9% and industrial rose by just 0.7%.
France produced a record 521.1 terawatt-hours of low-carbon electricity in 2025 as upgrades to existing nuclear reactors allowed the fleet to produce more power, according to data from the grid operator RTE. The latest report is not yet public on RTE’s website, but NucNet reviewed the findings. The electricity mix has largely remained steady for the last two years. France first achieved a 95% low-carbon grid back in 2024, RTE data shows.

Qcells has resumed solar panel assembly at its plant in Cartersville, Georgia, following a series of delays. By the end of this year, the South Korean-owned company said it plans to add the capacity to pump out 3.3 gigawatts of ingots, wafers, and cells per year. “We are proud to be back to work manufacturing the American-made energy the country needs right now,” Marta Stoepker, head of communications at Qcells, said in a statement. “Like any company, hurdles have and will occur, which requires us to adapt and be nimble, but our overall goal remains the same — to build a complete American solar supply chain.” The moves comes as MAGA warms to solar power as part of a broader “renewables thaw” that Heatmap’s Jael Holzman reported is part of a legal strategy.
Roughly two hours away, SK Battery America laid off nearly 1,000 workers at its factory northeast of Atlanta as automakers cool on electric vehicles. Friday marked the last working day for 958 employees, according to a federal filing the Associated Press reviewed.
A wave energy startup hoping to harness one of the trickier sources of renewable power just broke a record with its latest pilot project. Last month, Eco Wave Power deployed its EWP-EDF One technology Jaffa Port in Israel. The pilot test lasted nine days last month under moderate conditions with daily average wave heights between one and two meters. Throughout the test, the project generated about 2,000 kilowatthours of electricity. “Not only did we continue stable production during moderate wave conditions, but we also experienced the highest waves recorded at our site to date,” Inna Braverman, Eco Wave Power’s chief executive, said in a statement to the trade publication Offshore Energy. “Achieving record average and peak power production during 3-meter wave events provides meaningful validation of our technology’s performance potential as we scale toward commercial projects.”
Scientists discovered a molecular trick used by a unique group of plants to convert sunlight into food. Hornworts are the only known land plant that possesses internal compartments that concentrate carbon dioxide similarly to algae. A new study by researchers at the Boyce Thompson Institute, Cornell University, and the University of Edinburgh suggests that genes from the plants could be used to breed more resistant crops such as wheat. “This research shows that nature has already tested solutions we can learn from,” said Fay-Wei Li, a co-author of the study, said in a statement. “Our job is to understand those solutions well enough to apply them where they're needed most — in the crops that feed the world.”
