Geopolitics, the heightened importance of climate change, and the sheer size of the conference have transformed the event into something that it was never meant to be.

It didn’t attract a lot of attention, but for a few months, it looked like the United Nations climate process might break down.
There, process is substance: One of the most important acts every year is the selection of the next country to run the Conference of the Parties to the United Nations Framework Convention on Climate Change, or COP. This distinction normally rotates among the UN’s five regional country groups; next year, a country in the “Eastern Europe” group is due to host. All the members of a group must unanimously agree on which country will get to host.
This is a highly contingent way to decide who gets to host a climate conference. Really, the entire schema of UN regional groups represents a hangover of Cold War geopolitics that is now indefinitely unchangeable. (The “Western Europe” group is essentially the early members of NATO; it includes such notably non-western-European countries as Turkey, the United States, and — hilariously — Australia.)
The “Eastern Europe” group, meanwhile, amounts to more or less the former members of the Warsaw Pact. For obvious reasons, these countries cannot agree on a consensus choice in 2023. Russia, the group’s largest member, was not amenable to holding the COP in any eastern Europe NATO member state, such as Poland, Latvia, or Finland. The eastern European NATO members — as well as Ukraine, which is also in the UN regional group — were similarly opposed to holding the COP in Russia.
That meant that attention focused on the group’s countries in the Caucasus, at the edge of central Asia: Georgia, Azerbaijan, and Armenia. Yet difficulties presented themselves here too. Azerbaijan successfully seized an Armenian exclave earlier this year, evicting up to 120,000 Armenians as part of a campaign described as ethnic cleansing. Armenia blocked any Azeri bid to host the COP.
For the first time in the UN Framework Convention on Climate Change’s history, no country would have been able to lead COP the following year. Geopolitics had seemingly broken the consensus mechanism that makes the climate conference work.
This amounted to more than just a deficiency in party planning. It would have forced Bonn, Germany — the home of the UNFCC’s permanent headquarters — to host COP29, a kind of “break in case of emergency” default option. And it would have allowed the United Arab Emirates, a petrostate that has reportedly used the COP to make oil deals, to retain the conference presidency for at least another year.
That didn’t happen. Late last week, Armenia lifted its block of Azerbaijan’s bid, and the two countries mutually released prisoners in a gesture of good will. (Their rapprochement happened suspiciously close to President Vladimir Putin’s visit to the U.A.E.) Next year’s COP will seemingly happen in Baku, the Azeri capital.
But just because the COP process didn’t break doesn’t mean that it’s not being stretched. All is not well with the COP. During this year’s conference, a picture emerged of a COP being tested by a more rivalrous, conflict-prone world. Geopolitics, the heightened importance of climate change, and the sheer size of the conference have transformed the event into something that it was never meant to be.
This year, more than 100,000 people attended the COP. It was held at Dubai’s opulent Expo City, the Disney World-style convention campus initially built for the 2020 World Expo, the modern successor to World’s Fairs. Hundreds of nonprofit groups and companies, as well as more than 190 countries, ran public pavilions that advertised their climate accomplishments and views on decarbonization. Negotiators divided into different blocs: China and the United States, oil-producing states and small island nations, the West and the rest.
It wasn’t always like this. When the first COP was held in Berlin in 1995, the world was in a very different era, Lee Beck, the senior director for Europe and the Middle East at the Clean Air Task Force, told me. It was “the peak of multilateralism, followed by relative geopolitical stability and peace,” she said. The United States and the broader West set the agenda for global events.
“In the last two years — others would say the writing was on the wall as early as 2014 — geopolitical fragmentation really is visible,” she said. “You’re really pushing the limits of multilateralism at this one. One of the cracks is we’re unable to agree where the COP even will be.”
But geopolitics are not the only force stretching COP to the limit. Another is the sheer size of the event itself.
There used to be “big COPs” and “small COPs”: COP21, the 2015 meeting where the Paris Agreement was finalized, was a “big COP,” but the following year’s conference in Marrakech, Morocco, was a fairly minor one. Even COP21 was less than half the size of this year’s COP. And in one possible read, this year should have been a smaller COP — the biggest to-dos were formally launching the Loss and Damage fund and writing the Global Stocktake report, a kind of report card on the world’s climate progress (or lack thereof).
But small COPs don’t seem to happen any more. Since the pandemic ended and COP26 took place in Glasgow, Scotland, COPs have swollen in size, creating the age of the new “mega-COP.” More than 100,000 people attended the conference this year, making it by far the biggest COP ever. It was more than twice the size of last year’s confab in Sharm al-Sheikh, Egypt, which was previously the biggest COP ever. Most of those attendees had nothing to do with the negotiations ostensibly at the center of the conference — they were investors, technologists, scholars, scientists, or experts — and instead made up a de facto global trade show on climate solutions.
COP is now so big and climate is now so important that even the lack of news about the conference can generate news. When President Joe Biden declined to attend this year’s conference, The New York Times push-alerted it.
But there are possibilities that could improve the situation. One of them might be that COP simply becomes so unmanageable that it has to scale back. Few cities have the spare capacity to house an extra 100,000 visitors for 12 days. New York City, for instance, only has about 123,000 hotel rooms total. If COP were to keep growing, the problem would only get harder. When 150,000 people descended on San Francisco for Salesforce’s annual conference in 2015, the company docked a cruise ship in the bay to provide an extra thousand rooms.
There are solutions, Beck said. She noted this was the first year that every continent had held its own Climate Week: a smaller event focusing on more region-specific decarbonization challenges. This COP has also seen the emergence of country coalitions that rally around different issues or approaches. The set of countries that backed a pledge to triple renewable capacity, for instance, is different from the smaller coalition that wanted to triple nuclear capacity. These smaller, more sector-specific coalitions may have more ability to actually decarbonize and address climate change, she said.
For all these challenges, perhaps the biggest miracle is that the UNFCC process works at all, Eve Tamme, a former climate negotiator for the European Commission, told me.
“The UNFCCC process is based on consensus between almost 200 countries. Judging based on the complexity of the issue at hand and the divergence of views among the countries, it seems impossible that such a process could deliver anything at all,” she said. Even when you follow the negotiations closely, it may seem like there’s barely any movement at all, she said.
“But then again, we got the Kyoto Protocol,” she said. “And we got the Paris Agreement. So while it may look broken in the short term, somehow this dysfunctional process can still deliver.”

Current conditions: A bomb cyclone is headed up the East Coast, bringing more cold air and possible blizzard conditions to the Northeast, especially New England • Even Tampa Bay, where so-called snowbirds from the Northeast go to winter, could see snow by the end of this week • A storm system named Kristin is on track to bring thunderstorms, strong winds, and hail to Greece.

Sales of electric vehicles in Europe surged 30% to a record high last year, with battery-powered models outselling gas-burning cars for the first time last month, the Financial Times reported. The increase came despite a 38% drop in Tesla’s annual sales on the continent as Chinese rival BYD zoomed past Elon Musk’s automaker. Electric vehicles now account for 17% of EU car sales, up from 14% in 2024.
Tesla, meanwhile, is shifting gears. During a quarterly earnings call Wednesday evening, Musk announced plans to end production of the Model S sedan, its first fully original car design, and Model X SUV. “It’s time to basically bring the Model S and X programs to an end with an honorable discharge, because we’re really moving into a future that is based on autonomy,” he said. “So if you’re interested in buying a Model S and X, now would be the time to order it.” He said he would continue offering support for the existing models “for as long as people have the vehicles.” The big seller in the quarter, however, wasn’t any car at all. The company sold a record number of its utility-scale Megapack batteries. In a shareholder deck, the company told investors it had “achieved our highest quarterly energy storage deployments, driven by record Megapack deployments.” That brought revenue from the energy sector up 27% from 2024 to $12.8 billion.
The Department of Energy has overhauled a set of nuclear safety rules and shared them with companies it’s regulating without making the changes public. Citing leaked documents, NPR reported Wednesday that the agency had cut more than 750 pages from earlier versions of the rules, “leaving only about one-third of the number of pages in the original documents.” The changes include loosening rules on monitoring radiation leaks in groundwater and raising the threshold for an accident investigation. When I asked Emmet Penney, a nuclear historian and a senior fellow at the right-leaning Foundation for American Innovation, what he made of the report, he said the cuts eliminated a number of dubiously useful rules, including reducing how much security is required at nuclear stations, and praised Secretary of Energy Chris Wright. “Reducing costs burdens like unnecessary security for test reactors is a smart move from the DOE, as is clarifying vague radiation standards,” he told me. “These changes demonstrate Secretary Wright’s seriousness when it comes to catalyzing the nuclear renaissance.”
Also on Wednesday, the Energy Department announced a new initiative asking states to express interest in hosting “Nuclear Lifecycle Innovation Campuses,” where companies across the nuclear fuel cycle could set up shop, including recycling used fuel.
Electric and gas utilities requested almost $31 billion worth of rate increases last year, according to a new analysis by the energy policy nonprofit PowerLines. That compares to $15 billion in 2024. “In case you haven’t already done the math: That’s more than double what utilities asked for just a year earlier,” Heatmap’s Matthew Zeitlin wrote. Electricity prices went up by 6.7% in the past year, outpacing the 2.7% increase for prices overall. That makes power prices 37% more expensive than just five years ago. “These increases, a lot of them have not actually hit people's wallets yet,” PowerLines executive director Charles Hua told a group of reporters Wednesday afternoon. “So that shows that in 2026, the utility bills are likely to continue to rise, barring some major, sweeping action.” Those could affect some 81 million consumers, he said.

Drax built its business off a loophole in carbon accounting. Under the international rules on how to quantify emissions, the carbon from losing a tree is counted in the country where it’s felled. That meant chopping down old-growth trees in forests in the American South and shipping the vitamin-sized wood pellets to England to burn in a power plant counted as low-carbon energy in the United Kingdom — even if the power plant had to burn twice as much wood to equal the energy from coal. At long last, European and American policymakers are waking up to the realities of the wood pellet energy industry. Enviva, a major wood pellet producer, went bankrupt in 2024. Drax, meanwhile, has been losing green-energy subsidies in its native U.K. Now the company is facing the potential loss of the new biggest market for its wood pellets. Japan, compensating for the nuclear reactors still sitting idle 15 years after the Fukushima disaster, is set to soon surpass the U.K. as the world’s largest pellet importer market. But Japanese policymakers are now considering pulling support for all projects over 10 megawatts. “The real intention is quite simple: no new government support, phasing out. We don’t see any clear path of bringing down costs in the foreseeable future,” one government official told the Financial Times. “Existing projects might survive but no new projects are coming.”
New York City’s Department of Consumer and Worker Protection filed a lawsuit late last week against Radiant Solar and its owner, William James Bushell, demanding $18 million in restitution and about $1.7 million in penalties for damaging New Yorkers’ homes and leaving the customers across the city in debt. It’s the largest sum the city has ever sought from a home improvement contractor. The city argued that Radiant, as The New York Times put it, “engaged in a dizzying array of mechanical and monetary malfeasance for years.” That included padding loans with undisclosed “dealer fees,” signing customers up for large loans they didn't ask for, failing to file paperwork for customers to receive tax credits, and neglecting city approval processes. The company even allegedly ran a bogus sweepstakes for a new Tesla.
Redwood Materials’ big transformation is bringing in the money. Amid a two-year slump in lithium prices, the battery recycling startup announced the launch of a new venture last summer to provide grid-scale storage from restored battery packs. Yesterday, as Heatmap’s Katie Brigham wrote, “it’s clear just how much that bet has paid off.” The company raised a $425 million round of Series E funding for the new venture, called Redwood Energy. The money came from such investors as Google and Nvidia’s venture capital arms
A new PowerLines report puts the total requested increases at $31 billion — more than double the number from 2024.
Utilities asked regulators for permission to extract a lot more money from ratepayers last year.
Electric and gas utilities requested almost $31 billion worth of rate increases in 2025, according to an analysis by the energy policy nonprofit PowerLines released Thursday morning, compared to $15 billion worth of rate increases in 2024. In case you haven’t already done the math: That’s more than double what utilities asked for just a year earlier.
Utilities go to state regulators with its spending and investment plans, and those regulators decide how much of a return the utility is allowed to glean from its ratepayers on those investments. (Costs for fuel — like natural gas for a power plant — are typically passed through to customers without utilities earning a profit.) Just because a utility requests a certain level of spending does not mean that regulators will approve it. But the volume and magnitude of the increases likely means that many ratepayers will see higher bills in the coming year.
“These increases, a lot of them have not actually hit people's wallets yet,” PowerLines executive director Charles Hua told a group of reporters Wednesday afternoon. “So that shows that in 2026, the utility bills are likely to continue to rise, barring some major, sweeping action.” Those could affect some 81 million consumers, he said.
Electricity prices have gone up 6.7% in the past year, according to the Bureau of Labor Statistics, outpacing overall prices, which have risen 2.7%. Electricity is 37% more expensive today than it was just five years ago, a trend researchers have attributed to geographically specific factors such as costs arising from wildfires attributed to faulty utility equipment, as well as rising costs for maintaining and building out the grid itself.
These rising costs have become increasingly politically contentious, with state and local politicians using electricity markets and utilities as punching bags. Newly elected New Jersey Governor Mikie Sherrill’s first two actions in office, for instance, were both aimed at effecting a rate freeze proposal that was at the center of her campaign.
But some of the biggest rate increase requests from last year were not in the markets best known for high and rising prices: the Northeast and California. The Florida utility Florida Power and Light received permission from state regulators for $7 billion worth of rate increases, the largest such increase among the group PowerLines tracked. That figure was negotiated down from about $10 billion.
The PowerLines data is telling many consumers something they already know. Electricity is getting more expensive, and they’re not happy about it.
“In a moment where affordability concerns and pocketbook concerns remain top of mind for American consumers, electricity and gas are the two fastest drivers,” Hua said. “That is creating this sense of public and consumer frustration that we're seeing.”
The battery recycling company announced a $425 million Series E round after pivoting to power data centers.
Amidst a two year-long slump in lithium prices, the Nevada-based battery recycling company Redwood Materials announced last summer that it had begun a new venture focused on grid-scale energy storage. Today, it’s clear just how much that bet has paid off.
The company announced a $425 million round of Series E funding for the new venture, known as Redwood Energy. That came from some big names in artificial intelligence, including Google and Nvidia’s venture capital arm, NVentures. This marks the final close of the funding round, increasing the total from $350 million announced in October.
Redwood Energy adapts the company’s original mission — breaking down spent batteries to recover, refine, and resell critical minerals — to suit the data center revolution. Instead of merely extracting battery materials, the company can now also repurpose electric vehicle batteries that still have some life left in them as energy storage solutions for AI data centers, allowing Redwood to get value from the battery throughout its lifecycle.
“Regardless of where lithium prices are, if we can put [a lithium-ion battery] in a large-scale energy storage system, it can have a lot more value before we break it down into critical materials,” Claire McConnell, Redwood’s new VP of business development for energy storage, told me.
Over the past 12 to 18 months, she explained that the company had started to receive more and more used electric vehicle battery packs “in better condition than we initially anticipated.” Given the substantial electricity load growth underway, McConnell said the company saw it as “perfect moment” to “develop something that could be really unique for that market.”
At the time of Redwood Energy’s launch last June, the company announced that it had stockpiled over a gigawatt-hour of used EV batteries, with an additional 5 gigawatt-hours expected over the following year. Its first microgrid pilot is already live and generating revenue in Sparks, Nevada, operating in partnership with the data center owner and operator Crusoe Energy. That project is off-grid, supplying solar-generated electricity directly to Crusoe’s data center. Future projects could be grid-connected though, storing energy when prices are low and dispatching it when there are spikes in demand.
The company also isn’t limiting itself to used battery packs, McConnell told me. Plenty of manufacturers, she said, are sitting on a surplus of new batteries that they’re willing to offload to Redwood. The potential reasons for that glut are easy to see: already-slower-than-expected EV adoption compounded by Trump’s rollback of incentives has left many automakers with lower than projected EV sales. And even in the best of times, automakers routinely retool their product lines, which could leave them with excess inventory from an older model.
While McConnell wouldn’t reveal what percent of packs are new, she did tell me they make up a “pretty meaningful percentage of our inventory right now,” pointing to a recently announced partnership with General Motors meant to accelerate deployment of both new and used battery packs for energy storage.
While Redwood isn’t abandoning its battery recycling roots, this shift in priorities toward data center energy storage comes after a tough few years for the battery recycling sector overall. By last June, lithium prices had fallen precipitously from their record highs in 2022, making mineral recycling far less competitive. Then came Trump’s cuts to consumer electric vehicle incentives, further weakening demand. On top of that, the rise of lithium-iron phosphate batteries — which now dominate the battery storage sector and are increasingly common in EVs — have reduced the need for nickel and cobalt in particular, as they’re not a part of this cheaper battery chemistry.
All this helped create the conditions for the bankruptcy of one of Redwood’s main competitors, Li-Cycle, in May 2025. The company went public via a SPAC merger in 2021, aiming to commercialize its proprietary technique for shredding whole lithium-ion battery packs at once. But it ultimately couldn’t secure the funds to finish building out its recycling hub in Rochester, New York, and it was acquired by the commodities trading and mining company Glencore last summer.
“We started really early, and in a way we started Redwood almost too early,” JB Straubel, Redwood’s founder and Tesla’s co-founder, told TechCrunch last summer. He was alluding to the fact that in 2017, when Redwood was founded, there just weren’t that many aging EVs on the road — nor are there yet today. So while an influx of used EV batteries is eventually expected, slower than anticipated EV adoption means there just may not be enough supply yet to sustain a company like Redwood on that business model alone.
In the meantime, Redwood has also worked to recycle and refine critical minerals from battery manufacturing scrap and used lithium-ion from consumer electronics. Partnerships with automakers such as Toyota, Volkswagen, and General Motors, as well as global battery manufacturer Panasonic, have helped bolster both its EV battery recycling business and new storage endeavor. The goal of building a domestic supply chain for battery materials such as lithium, nickel, cobalt, and copper also remains as bipartisan as ever, meaning Redwood certainly isn’t dropping the recycling and refining arm of its business, even as it shifts focus toward energy storage.
For instance, it’s also still working on the buildout of a recycling and battery component production facility in Charleston, South Carolina. While three years ago the company announced that this plant would eventually produce over 100 gigawatt-hours of cathode and anode battery components annually, operations on this front appear to be delayed. When Redwood announced that recycling and refining operations had begun in Charleston late last year, it made no mention of when battery component production would start up.
It’s possible that this could be taking a backburner to the company’s big plans to expand its storage business. While the initial Crusoe facility offers 63 megawatt-hours of battery energy storage, McConnell told me that Redwood is now working on projects “in the hundreds of megawatt-hours, looking to gigawatt-hour scale” that it hopes to announce soon.
The market potential is larger than any of us might realize. Over the next five or so years, McConnell said, “We expect that repurposed electric vehicle battery packs could make up 50% of the energy storage market.”
