See also: federal policy, batteries, and electricity demand.

The clean energy industry is beginning to report to investors and the public on its first brush with Donald Trump’s trade policy. While earnings season has only just begun, already some broad themes are emerging across the sector: Tariffs hurt. Batteries are getting more expensive. And there’s big demand for power, especially natural gas.
Four big clean energy companies that have reported results so far — inverter and battery maker Enphase, turbine manufacturer GE Vernova, electric vehicle giant Tesla, and developer and utility NextEra — mentioned tariffs prominently in either their earnings reports or their analyst calls. GE Vernova said that tariffs would result in $300 million to $400 million of additional costs. Enphase said that tariffs would take off two percentage points from its margin in the second quarter and six to eight points of gross margin in the third quarter. Tesla said that “increasing tariffs may cause market volatility and near-term impacts to supply and demand.”
Tesla’s executives — including chief executive Elon Musk — expanded on that market volatility later in a call with investors and analysts, with Musk saying that he was an “advocate of predictable tariff structures, free trade, and lower tariffs.” Musk added that economic uncertainty could continue to weigh on Tesla’s auto sales, which notably declined in the first three months of the year. “When there is economic uncertainty, people generally want to pause on doing a major capital purchase like a car,” he observed.
NextEra chief executive John Ketchum said the company had “dramatically diversified where we source our solar panels” and was not affected by the recent announcement of high tariff rates on solar panels from Southeast Asia. He also specified to analysts that “we source our wind turbines from the U.S., with manufacturing in Florida.” The company estimated that it has “$150 million in tariff exposure through 2028, on over $75 billion in expected capital spend,” Ketchum said.
Enphase chief executive Badri Kothandaraman attempted to tread delicately on the tariff issue. “While the global policy environment remains fluid with tariffs, with interest rates and subsidies constantly evolving, we are moving quickly to realign our supply chain to minimize downside across a range of scenarios,” he said. “While we cannot control the macroeconomic conditions, we can absolutely control our response.” GE Vernova chief financial officer Ken Parks described tariffs as a “continued increase in the cost base,” and said that the combined tariffs on steel plus various imports from Canada, Mexico, China — which is facing import duties of 145% or more, depending on the product — affect about a quarter of its spending.
A lot of that tariff impact comes from the battery supply chain, which China dominates. For Tesla, that means its fast growing energy storage business is particularly at risk. While the company has made some efforts to onshore stationary storage battery production, its chief financial officer, Vaibhav Taneja, said that domestic production would ultimately account for only a “fraction” of its battery needs, and even that would “take time.”
Enphase was similarly upfront about the impact on its battery supplies. “We are no exception. We use Chinese sources for the cell packs,” Kothandaraman said. He explained that thanks to the tariffs, making batteries domestically with Chinese cells “therefore turns out for us that whether we make it domestically or whether we make it outside the U.S., our costs are becoming approximately the same. And the cost impact is significant.” In other words, the tariffs make domestic battery production less appealing than it was before. Kothandaraman said that the company is working on establishing a non-Chinese supply chain, which will take six to nine months.
NextEra’s Ketchum said that the company had made “arrangements” to buy batteries made in the U.S. “for a significant portion of our backlog,” and that its contracts for non-Chinese-sourced batteries required the supplier to cover any tariff-related costs. Ketchum did say that the domestic batteries meet local content requirements for tax subsidies under the Inflation Reduction Act, however “there are certain components that come in from outside the United States.” Overall, Ketchum said, “our tariff exposure on batteries is expected to be negligible.”
All four companies are heavily exposed to various energy regulatory and subsidy plans that may or may not survive the double-whammy of the congressional Republicans’ budget-making priorities and the Trump administration’s desire to roll back environmental regulations.
Tesla’s revenue from emissions credits that other carmakers buy to comply with California’s fleet emissions standards was $595 million in the first quarter of this year, compared to $409 million of net income — implying that the company would have lost money if not for the credits. This Trump administration has already attempted to take away California’s ability to set emissions standards, as it did the first time around. Then it was not successful, and this time it might not have to be — the Supreme Court on Wednesday indicated that it would be open to a lawsuit from the fossil fuel industry challenging California’s limits.
Kothandaraman said that “the lack of certainty” around the fate of the Inflation Reduction Act, which is currently being hashed out in Congress, “is definitely a factor” in explaining what one analyst described as “a bit of paralysis on the customer side.” He was hopeful that “demand will be unlocked” once there’s “clarity” on IRA tax credits.
Meanwhile, GE Vernova said that offshore wind orders had fallen by 43%, “as a result of ongoing U.S. policy uncertainty and permitting delays.” It also took a $70 million charge related to the cancellation of a deal to supply 18-megawatt turbines in New York.
Musk bragged that Tesla’s Megapack utility storage system “enables utility companies to output far more total energy than would otherwise be the case,” and that “utility companies are beginning to realize this and are buying in our Megapacks at scale.” While the company deployed almost 40 gigawatt-hours of battery storage in the past 12 months — an impressive amount based on the current level of grid battery storage in the U.S. — Musk predicted that Tesla could end up deploying “terawatts” of storage on an annual basis.
NextEra has a large renewables development business, and Ketchum sees the uptick in demand for electricity as a boon: “When I look at the demand and the outlook in the renewable sector going … we just continue to see strong demand across the board, with hyperscalers being a nice sized part of that.”
GE Vernova competed with NextEra for the most investor-friendly demand growth story — though its is not a particularly climate-friendly one. The company says it has a backlog of 29 gigawatts of natural gas turbine orders, with an additional 21 gigawatts of reservations that will turn into future production. Its earnings before interest, taxes, depreciation, and amortization for its power business jumped from $345 million in the first quarter of last year to $508 million in the first quarter of this year, while its margins grew from 8.6% to 11.5%.
About a third of its reservations for turbines are for data centers, Scott Strazik, the company’s chief executive said. Some more were to provide baseload power. And the rest? “A healthy amount of these are also F-class gas turbines to just strengthen the durability and the resiliency on the grid,” he said.

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.
