Kamala Harris quickly rang up endorsements from Democratic elected officials and convention delegates Sunday afternoon after President Joe Biden ended his re-election campaign, making Vice President Harris the likeliest Democratic nominee for the presidency of the United States. Many of these plaudits came from figures in the climate policy space, but few were quite as vociferous as the one from Gina McCarthy, a director of the Environmental Protection Agency under President Obama and White House climate advisor under Biden.
“Vice President Harris would kick ass against Trump,” she said in a statement. “She has spent her whole life committed to justice, fighting for the underdog, and making sure that no one is above the law. She will fight every day for all Americans to have access to clean air, clean water, and a healthy environment.”
When Harris has had the chance to formulate climate action on her own — as the attorney general of California, as a U.S. senator, as a candidate for the Democratic presidential nomination in 2020 — it has tended to be aggressive in its timelines for decarbonization and heavily focused on the harms that fossil fuel extraction and processing inflict on marginalized communities.
As vice president, however, she has been subsumed into the rollout of both the Inflation Reduction Act and the Infrastructure Investment and Jobs Act. In some cases, the programs she’s pitched and praised have an organic connection to her own personal policy work — a grant program for electric school buses, for instance, the launch of which was the source of one of her more enduring Kamala-isms: “Who doesn’t love a yellow school bus?”
Assuming she wins the party’s nomination and then, finally, the White House, a Kamala Harris climate agenda would no doubt look much like Biden’s. To people who’ve been paying attention all along, however, there’s no reason to think she couldn’t push the country even more zealously toward decarbonizing.
For one, there’s the historical record. Harris not only endorsed Green New Deal legislation in 2019, she also put out a climate plan during her campaign that included $10 trillion of public and private spending and called for reaching net-zero by 2045, achieving a carbon neutral electric grid by 2030, no new fossil fuel leasing on public lands, and a carbon pollution fee. While expansive, Harris’s plan was not the work of someone like Jay Inslee, who has legislated on climate for years, or Bernie Sanders, who was willing to simply outbid his fellow candidates on progressive policy, but her climate policy was the process of consulting with climate activists. In fact, her team had reached out to Inslee’s after he dropped out for advice on climate, Jamal Raad, Inslee’s campaign communications director, told me.
“If we jump in the Wayback Machine, [Harris] was one of the most ambitious presidential candidates in the 2020 primary cycle,” Justin Guay, program director at Quadrature Climate Foundation, told me. “She had the largest proposed spending plan of any candidate not named Bernie. She promised a sum 10 times that of the greatest climate president we’ve ever had, Joe Biden.” Importantly, he added, she focused on “sticks, not just carrots,” including investigating and bringing lawsuits against fossil fuel companies, as she’d done in California. This, he said, is “red meat for the climate base.”
Where she did stand out in the Senate, on the campaign trail, and in the Biden administration was in her focus on environmental justice, an issue combining green politics and racial justice that she used to reach out to the party’s left wing. By the time the she was picked to be President Biden’s vice presidential nominee, she had won the praise of both the youth-led Sunrise Movement (which has since protested outside her Southern California home and notably withheld its support from Biden during his reelection campaign) and Evergreen Action, a climate policy group built by former Inslee staffers. “She made environmental justice central to her climate plans on the presidential campaign,” said Raad, an Evergreen Action cofounder.
In the summer of 2019, she joined up with Alexandria Ocasio-Cortez on a bill that would have required all climate-related legislation to undergo a review of its effect on “frontline communities,” those living adjacent to energy-related facilities, which tend to be disproportionately populated by poor people of color, and created offices of climate equity within the Congressional Budget Office and the Office of Management and Budget.
While this particular piece of legislation went nowhere, the motivating ideas have been all over the Biden-Harris White House’s policy agenda — in tax benefits directed toward projects in “energy communities;” in the Justice40 Initiative, which aims to direct 40% of climate and related spending to flow toward disadvantaged communities; and in the Greenhouse Gas Reduction Fund, a.k.a. “green banks,” aimed at making climate-friendly investing more affordable.
That’s all great, Raad told me. But he also added, “What’s more relevant has been how central she’s made climate in her vice presidency as one of her top priorities.” Harris reached out to Raad and others in the run-up to the IRA’s passage, he said. “She held a town hall. She barnstormed the country. As far as folks wanting further momentum in the next presidency, that’s the more relevant development — that she wanted to be associated with climate action.”
Whatever her policy priorities as president, they would have to fit between the lines of what would be, at best, narrow majorities in both chambers of Congress, limited by the filibuster and reconciliation process, along with large policy shifts that any new administration will have to deal with, such as the expiration of key portions of the 2017 Tax Cuts and Jobs Act in 2025. It will be a far distance from the heady days of the 2020 Democratic primary campaign, when Harris eagerly participated in a bidding war between the candidates for the most aggressive and expansive climate program — less Frank Capra, more Alan J. Pakula.
“The reality is that the climate movement should focus as much, if not more, on creating the conditions that force politicians to act on climate as we do pushing for candidates with a hawkish climate policy platform to begin with,” Guay told me. “That was the greatest lesson from the Joe Biden era. He was no climate hawk when he entered the 2020 primaries,” but thanks to decades of unrelenting pressure and calls for more policy ambition, “he emerged the most powerful climate president we’ve ever had.”
Raad, too, emphasized the importance of realpolitik at this point in history. Having a president willing to put herself on the line for climate policy is important — “even if we don’t get major legislation done,” he told me. “We need to make sure the IRA is implemented effectively in the fullest way possible. We need a very careful eye towards writing regulations that are as effective as possible so they’re not getting overturned by Federalist Society judges.” Getting money out the door will be key, he said, “and that’s why we need an advocate in the White House.”

A new report from LevelTen Energy shows that advance purchase prices are down for solar but up for wind.
The renewables market is in a state of flux. On the one hand, the tax credits that were a key pillar of wind and solar project financing have started to expire, while the race to be up and running in time to claim those that remain is on.
At the same time the renewables industry is getting whacked by federal tax policy, it’s also getting a shot in the arm from hyperscalers and data center developers, many of whom are hungry for power that can be deployed quickly to the grid and complies with their clean energy pledges.
“There’s a massive onslaught of demand, not enough supply to meet that demand and then Trump’s administration effort to slow down certain types of supply,” Jon Powers, the president of solar and storage developer CleanCapital, told me, describing how data center buyers are snapping up whatever power they can.
So what does this mean for pricing in the market? LevelTen, a marketplace for power purchase agreements, looked at the data and, in a report released Tuesday, found that solar PPAs were almost 5% cheaper in the second quarter of this year compared to the first quarter.
LevelTen attributed this decline in part to an especially steep drop in prices in CAISO, the California electricity market; excluding CAISO, solar PPA prices dropped slightly less than 2%. And while those hyperscalers are still buying, LevelTen found, other commercial and industrial customers are pulling back — what the analysts described as a “continued softening in the market’s buy-side.”
“We saw a lot less corporate energy buyers in the space in 2025 — 40% less — and that is just due to the increase of hyperscalers and data centers getting projects and snapping them up quickly,” Sarah Wolf, LevelTen’s director of North American transactions, told me.
To explain California specifically, Wolf said that the market there tends to be more volatile than in the rest of the country due to the expense and regulatory hurdles to development. With fewer new projects coming online, especially as compared to a larger, more light-touch market like Texas, individual project pricing can swing average prices more.
The tax credit cliff is “creating this very competitive atmosphere, where buyers are feeling like — in order to safe harbor their equipment, to keep on the development timelines that they have — they need to get a PPA in place,” Wolf said. “They’re looking competitively for a buyer. That’s driving some pricing down.” The same holds for renewables developers, who have wanted to get a PPA in place as quickly as possible, giving leverage to buyers who can demand lower prices.
The other factor driving down prices LevelTen identified was potential revisions to standards issued by the Greenhouse Gas Protocol, which are currently the subject of a long and fraught overhaul process.
“We have many buyers who are fully leaning in and want to contract now,” Wolf said. “And we have buyers who are in a kind of a ’wait and see’ — they want to better understand what that’s going to be, so there’s not a risk that they might have to unwind something.”
As for wind, PPA prices have actually risen, according to LevelTen’s data — up 5.5% on the quarter and 17.5% on the year. “We’re also seeing wind just being less competitive than solar,” Wolf added.
The report attributed this to tariffs, gas prices pushing up delivery costs, and the “ongoing federal permitting bottleneck that has largely ground new-build wind development to a standstill.” That means specifically the Department of Defense’s efforts to hold up wind projects on potentially spurious national security grounds.
This has meant a “fast-dwindling pipeline of viable wind assets,” LevelTen’s report says, “and price premiums for fully permitted projects available for offtake.”
In short, the best news for individual wind developers may be bad news for the industry — and the climate — as a whole.
Cement, plywood, and some electronic equipment will face 50% levies. But the real cost is much higher.
Here we go again. The United States will impose new 50% tariffs on a slew of imports from Canada, the White House announced on Monday afternoon. The trade levies — which will hit more than 500 categories of goods, from anoraks, beer, and curtains, to yarn, wool, and whey protein — will take effect in 30 days.
The new tariffs don’t seem to be wildfire-related. President Trump threatened to impose new tariffs last week after smoke from Canadian wildfires drifted south over the northern U.S. border, but administration officials have claimed to CNN that these new levies were already in motion by then.
Even so, a few aspects of the announcement stand out. Most important, at least from a generalist perspective, is the legal mechanism that President Trump is using to apply them: Section 338 of the Smoot-Hawley Tariff Act. This passage, which has never been used by a previous president to levy tariffs, allows the United States to tax trade from countries that the president says have “discriminated against” U.S. commerce.
Significant, too, is the fact the White House asserts this new kind of tariff could apply to any kind of product — even those that would normally be covered by the North American free trade pact, the U.S.-Mexico-Canada Agreement. So far, the “Big Three” automakers — whose supply chains cross the Mexican or Canadian borders half a dozen times before a car is finally assembled — have avoided major tariff danger because auto parts and other inputs fall under the USMCA’s auspices. If the White House now thinks it can levy taxes despite that pact, then the risks for Ford, General Motors, and their suppliers have increased.
Energy and critical minerals are exempt from the new tariffs, so Canadian crude oil, gasoline, diesel, natural gas, and electricity will presumably keep flowing into the United States. (That explicit carve-out might be ominous in its own right, because energy had been protected by USMCA so far, too.) By omitting energy, Trump and his officials may be calculating they can avoid major inflationary hazards from this round of tariffs.
Who knows. In any case, to my eye, these tariffs do seem like they could aggravate construction costs and possibly contribute to wider U.S. inflation. There’s already some evidence that data centers are driving a new wave of inflation, for instance, by hiking construction input and labor costs. Yet data centers use a lot of cement — and cement will now face a 50% tariff under the new regime. So too will plywood, plaster, and paperboard, as well as industrial cooling equipment, chemicals, and some circuit boards.
I could keep listing the potential economic costs here — I could point out that overall inflation risk is rising or that average U.S. gas prices rose to $4 a gallon today on the Iran war news — but I think it’s important to look at least one step beyond the hits to commerce alone.
I mentioned earlier that these tariffs are meant to punish “discrimination.” In this case, some of the “discrimination” appears to be what some Canadian provinces did to retaliate against the president’s earlier tariffs. The state-owned liquor stores in Quebec and Ontario, for instance, stopped buying U.S.-made booze after Trump slapped 25% tariffs on Canada in March 2025; those boycotts are mentioned by name in today’s proclamation. Canada, you see, is not supposed to respond to Trump’s tariffs. It is just supposed to take it — just like it’s supposed to take the constant stream of falsehoods, abuse, belittling, and invasion threat.
Over the past few years, politicians and pundits have learned to respond to Trump’s policies by appealing to U.S. self-interest — by explaining how the president’s policies are making Americans poorer. It is a sensible strategy for a morally denuded era. A recent statement from Senate Minority Leader Chuck Schumer about Canada, for example, criticized the president for hurting “our closest ally and partner … right when summer tourism season is arriving.” I get the move here — and I think, in some sense, Schumer is trying to avoid polarizing Trump’s treatment of Canada along partisan lines — but Canadians are more than their tourism dollars.
For the past several years, Trump has threatened to strip Canada of its sovereignty and its dignity. He has treated what was once a deep and secure relationship as something to be bartered and mined and dissipated. It is a mucilaginous approach to statecraft, and as recent reporting has made clear, its long-term costs will exceed any simple accounting. We Americans have been robbed of an honorable friendship. Some losses cannot be counted in dollars.
In seven years of owning an electric car, I’ve done practically no maintenance. My 2019 Tesla Model 3 has gotten a new set of tires and windshield wipers, but because an EV doesn’t require oil changes or many of the other occasional chores that come with gas cars, that’s about it.
The one thing I have had to fix is the battery, and no, I don’t mean the big one that makes the car go.
Twice in those seven years, I’ve replaced the car’s 12-volt battery. This is the toolbox-sized unit that’s familiar to millions — it’s what the phrase “car battery” used to mean back before electric vehicles. Lots of new or aspiring EV drivers may not even realize their car has a second, smaller battery borrowed from combustion days. But this crucial holdover — the most recycled object on the planet, by the way, at a rate of more than 100 million annually — has already been a source of annoyance for EV engineers and drivers.
The reason behind the weird setup is straightforward. Despite the fact that EVs are effectively giant batteries on wheels, they need a backup source to operate the power windows and doors. If you’re in a car accident that disables the main battery, for instance, you need power to the doors to escape, and also a way to disconnect the high-voltage battery. Thus, the old-fashioned 12-volt battery squirreled away deep inside the car to protect it during collisions.
It’s not just a matter of backup power, either. A large, high-voltage battery would have to step down its electrical output for applications other than pushing a car down the road; it’s simpler to power them with a 12-volt battery and use the big unit to recharge the smaller one. After all, legacy carmakers have decades of experience building this kind of electrical system for gasoline-powered cars. Some EVs also use the 12-volt setup to disconnect the high-voltage power supply when the car is simply parked for a long time.
All this makes solid engineering sense. It also means that a sleek, modern EV is reliant upon the clunky car battery of yesteryear. Some drivers, including those in new Kia EVs, have said they can’t drive their cars even though there’s plenty of juice in the big unit because something went wrong with the 12-volt. As one Reddit commenter wrote: “It seems absurd to design a car that can run out of electrons and not be able to start while it is carrying 70 kWh of energy in a giant battery.” Yet that’s exactly the reality.
There are a few reasons why. As InsideEVs has noted, the rugged old 12-volt keeps getting more and more responsibility. Nowadays, the constant cellular connectivity of modem EVs — as well as features that can be used while the car is parked, such as security systems that tap into the vehicle’s exterior cameras to monitor the surrounding area — can cause a continuous drain on the 12-volt battery. That requires the car’s big battery to “wake up” and recharge the smaller one, which not only bleeds the vehicle’s driving range while it’s sitting still but also causes lots of recharging cycles for the 12-volt, prematurely aging the small battery.
Rivian had notorious problems from this issue for the older R1T and R1S and had to engineer a fix. Hyundais and Kias, meanwhile, have had longstanding issues with their Integrated Charging Control Unit, the system that recharges the 12-volt battery, that have caused a variety of recalls and headaches widely documented in online posts and videos. Chevy and Toyota have endured their own growing pains trying to make a low-voltage electrical system work well inside an EV.
But the car companies are getting smarter. Rather than duplicating what works in gas cars, more of them are building EV-specific systems with this application in mind. For example, the 12-volt in an EV doesn’t need to provide the big single burst needed to start up a gas engine, but it does need to be able to survive being subjected to more recharging cycles. In other words, it’s not that using these batteries in modern EVs is a bad idea — we just need to be smarter about how.
Perhaps EV builders one day will engineer away the old battery. Rivian, for one, has filed a patent for an electrical architecture that would work without a low-voltage battery at all. But those workarounds are a long way out. For now, even the most futuristic-feeling electric cars are stuck with the same kind of battery your dad had to jump-start in the church parking lot that time you left the AC on and the engine wasn’t running. My big, high-voltage battery might keep running forever, even as its capacity continues to diminish. But inevitably, I’ll need another small, dumb battery when this one goes kaput.
