Republicans launched multiple attacks against EVs, clean air and American jobs this week, at the behest of the oil industry that funds them. These attacks won’t be successful, and EVs will continue to grow regardless, and inevitably take over for outdated gasoline vehicles.
However, these republican attacks on EVs will still have some effect: they will diminish the US auto industry globally, leading to job losses and surrendering one of the jewels in the crown of American industry to China, where there is no similar effort to destroy its own domestic EV industry.
But they should inspire worry for Americans, because they will only harm the country’s domestic manufacturing base in the face of a changing auto industry.
Republicans keep trying to kill clean cars
The last time a republican occupied the the White House, we saw similar efforts to try to raise fuel and health costs for Americans, and to block superior EV technology from flourishing. That didn’t work in the end, and EVs continued to grow both during that period and after.
All the while, fossil fuels have maintained their privileged policy position, being allowed to pollute with impunity and costing the US $760 billion per year in externalized costs. Much of that subsidy is accounted for in the cost of pollution from gas cars, which are one of the primary uses of fossil fuels, which means that, in fact, gasoline vehicles receive much more subsidy than EVs do.
And yet, EVs still managed to grow substantially, despite these headwinds. EV sales have continued to grow, both in the US and globally, even as headlines incorrectly say otherwise. The republican party’s attempts to kill them were futile, and will continue to be.
It didn’t work, but it did delay progress
However, anti-EV actions from Mr. Trump and the republican party did manage to delay progress from where it could have been if America actually instituted smart industrial policy earlier.
Surely the American auto industry would be ahead of where it is now if those investments had had time to come online. But instead, republicans are currently trying to kill those jobs, which has already led to several manufacturing projects being cancelled this year, depriving Americans of the economic boost they need right now.
Meanwhile, there’s one place that this sort of stumbling isn’t happening: China.
China is taking advantage
China has spent more than a decade focusing on securing material supply, building refining capacity, developing their own battery technology, and encouraging local EV manufacturing startups.
This has paid off recently, as Chinese EVs have been rapidly scaling in production in recent years. It took a lot of the auto industry by surprise how rapidly Chinese companies have scaled, and how rapidly Chinese consumers have adopted them, after having an initially slow start.
But that adoption hasn’t just been local, it’s also global. Last year, China became the largest auto exporter in the world, taking a crown that Japan had held for decades. But the change was even more dramatic than that – as recently as 2020, China was the sixth-largest auto exporter in the world, just behind the US in 5th place.
China’s dramatic turn upward started in 2020, and now it’s in first place. Meanwhile, because of all the faffing about, the US remains exactly where it was in 2020 – still in fifth place. Well, sixth now, since China eclipsed us (and everyone else).
But tariffs have been tried before, and they didn’t work. When Japan had a similarly meteoric rise to global prominence as an auto manufacturer in the 1970s and 80s, largely due to their adoption of new technology, processes, and different car styles which incumbents were ignoring, the US tried to stop it with tariffs.
All this did was make US manufacturers complacent, and Japan still managed to seize and maintain the crown of top auto exporter (occasionally trading places with Germany) from then until now.
Then as now, the true way to compete is to adapt to the changing automotive industry and take EVs seriously, rather than giving the auto industry excuses to be complacent. But instead, republicans aren’t doing that, and in fact are working to ensure the American auto industry doesn’t adapt, by actively killing the incentives that were leading to a boom in domestic manufacturing investment.
US auto industry jeopardized by republicans
Make no mistake about it: destroying EV incentives, and allowing companies to pollute more and innovate less, will not help the US auto industry catch up with a fast moving competitor.
As we at Electrek have said for years, you cannot catch up to a competitor that is both ahead of you and moving faster than you.
It also applies to nations, which could have spent the last decade doing what the Chinese auto industry has been doing, but instead non-Chinese automakers have been begging their governments for more time, even though it’s not the regulations that threaten them, it’s competition from a new and motivated rival that is moving faster and in a more determined manner towards the future.
The way that we get around this should be clear: take EVs seriously.
But that’s not what republicans are doing, and in doing so, they are signing the death warrant for an important US industry in the long term.
Another thing republicans are trying to kill is the the rooftop solar credit, which means you could have only until the end of this year to install rooftop solar on your home before the cost of doing so goes up by an average of ~$10,000. So if you want to go solar, get started now, because these things take time and the system needs to be active before you file for the credit.

International equipment manufacturer Vermeer has unveiled a full-scale prototype of its Interlune excavator, a machine designed to ingest 100 metric tons of rocks and dirt per hour, extracting valuable helium as it makes its way across the surface … of the Moon.
Helium plays a critical role in the manufacturing of semiconductors, chips, optics, and all the other stuff that makes EVs, autonomy, the Internet, and the rest of twenty-first century life possible. The problem is that, despite being the second-most common element in the universe, helium is pretty rare on Earth – and we are rapidly running out. As such, there are intense economic and political pressures to find new and reliable sources of helium somewhere, anywhere else, and that demand has sparked a new modern space race focused on harvesting helium on the Moon and getting it back home.
To that end, companies like American lunar mining startup Interlune and the Iowa-based equipment experts at Vermeer are partnering on the development of suite of interplanetary equipment assets capable of digging up lunar materials like rocks and sand from up to three meters below the surface, extract helium-3 (a light, stable isotope of helium believed to exist in abundance on the Moon), then package it, contain it, and ship it back to Earth.
“When you’re operating equipment on the Moon, reliability and performance standards are at a new level,” says Rob Meyerson, Interlune CEO. “Vermeer has a legacy of innovation and excellence that started more than 75 years ago, which makes them the ideal partner for Interlune.”
The company showed a scaled prototype of the machine at the 2025 Consumer Electronics Show (CES) in Las Vegas (above), emphasizing the need to develop new ways to operate equipment assets in the extreme temperatures of extraplanetary environments beyond diesel or even hydrogen combustion.
On the airless surface of the moon, it would be impossible for an internal combustion engine to operate on the moon’s surface because there is no oxygen for combustion. Electrically powered machines seem the obvious solution with solar power generation supplying the electricity. But the answer is not that simple.
Temperature changes on the surface of the moon are extreme. They can soar to 110° C and plummet to -170° C. Developing electric construction machinery to perform in this environment is no easy task, but Komatsu is tackling issues one by one as they appear. Using thermal control and other electrification technologies, we are engineering solutions.
Despite Komatsu’s apparent head start, however, Vermeer seem to pulled ahead – not just in terms of machine development, but in terms of extraction potential as well.
“The high-rate excavation needed to harvest helium-3 from the Moon in large quantities has never been attempted before, let alone with high efficiency,” said Gary Lai, Interlune co-founder and CTO. “Vermeer’s response to such an ambitious assignment was to move fast. We’ve been very pleased with the results of the test program to date and look forward to the next phase of development.”
Interlune is funded by grants from the US Department of Energy and NASA TechFlights. In 2023, the company received a National Science Foundation (NSF) Small Business Innovation Research award to develop the technology to size and sort lunar regolith (read: dirt). Interlune has raised $18 million in funding so far, and is planning its first mission to the Moon before 2030.

Solar power CEOs believed the billions of dollars that they invested in Republican congressional districts would ultimately shield their industry from President Donald Trump’s threats to end federal support for renewable energy.
But they may have been disastrously wrong. The tax bill that House Republicans passed this week is a “worse than feared scenario” for solar, analysts at the investment bank Jefferies told clients in a note.
The legislation would terminate key tax credits that have supported the industry’s growth, triggering a broad sell-off of solar stocks on Thursday. The bill does still have to pass the Senate, where Jefferies expects the “unworkable” provisions to be undone.
But in its current form, the tax bill effectively takes a “sledgehammer” to President Joe Biden’s Inflation Reduction Act, the Jefferies analysts said. The legislation would “upend an economic boom in this country that has delivered an historic American manufacturing renaissance,” said Abigail Ross Hopper, CEO of the lobby group Solar Energy Industries Association.
Hopper excoriated the tax bill as “willfully ignorant” of the role that solar power and battery storage is playing in meeting electricity demand from U.S. consumers and businesses.
“If this bill becomes law, America will effectively surrender the AI race to China and communities nationwide will face blackouts,” she warned.
Sunrun CEO Mary Powell told CNBC in an interview Thursday that the legislation could result in the loss of 250,000 jobs and would increase the cost of electricity for consumers. The rooftop solar installer had its worst performance ever Thursday, with shares dropping 37%.
Trump, for his part, called on the Senate to pass what he calls the “one, big, beautiful bill” as soon as possible. “There is no time to waste,” the president said on his social media platform Truth Social Thursday.
Solar and battery storage is the fastest growing energy source in the U.S., making up 81% of expected power additions to the grid in 2025, according to the Energy Information Administration.
But the tax bill would basically kill the two tax credits that have done the most to enable the surge of solar power. It terminates the investment and electricity production credits for clean energy facilities that begin construction 60 days after the legislation is enacted or enter service after 2028. This also applies to wind power, which is growing at slower place in the U.S.
“That’ll put a massive slowdown on the amount of clean energy that gets added to the grid,” said Ben Smith, associate director of Rhodium Group’s energy and climate practice. The deployment of clean energy to the grid could decline by 57% to 72% over the next decade, according to Rhodium.
Clean energy projects also cannot claim the tax credits as early as next year if they receive “material assistance” from prohibited foreign entities. This mostly targets projects that source basic materials from China, such as glass for solar panels or cobalt and lithium for batteries, King said.
“It really does serve in our estimation as a de facto repeal of the credit as early as next year,” he said. The manufacturing tax credit that has supported companies such as First Solar remains in place until 2031, though its also subject to the foreign entity restrictions.
The tax bill is “disastrous” for the rooftop solar industry, Guggenheim analyst Joseph Osha told clients. It terminates tax credits for companies like Sunrun that lease solar equipment to customers. About 70% of the residential solar industry is using lease arrangements, Osha said.
GOP senators could tweak bill
But some Republican senators have pushed back on the legislation, raising at least some hope for the industry that the bill’s harshest provisions will be softened. Sen. Shelley Moore Capito, R-W.V., told Politico that the tax bill acts like a blanket repeal of the tax credits.
“I would expect that to change,” Capito told Politico on May 13. “There has been job creation around these tax credits.”
Indeed, GOP congressional districts would get hit the hardest if the credits are terminated. Some 81% of IRA investment has gone to Republican districts, according to data from advocacy group E2.
A slowdown in solar deployment would come at the same time that electricity demand is increasing due to the construction of artificial intelligence data centers, reindustrialization and the broader electrification of the economy.
Renewables can be deployed the most quickly to meet demand right now because solar, battery storage and wind represent 92% of the power projects waiting for connection to the grid, according to Interconnection.fyi, an organization that tracks connection requests.
Natural gas demand is also soaring in the U.S., but the wait time for new turbines is five to six years if an order is put in now, said Reid Ramdathsingh, an analyst at consulting firm Rystad Energy. While growth may slow, solar and batteries will continue to be deployed because there really isn’t an alternative, Ramdathsingh said.
“The demand is there for energy,” he said. “Gas is not able to meet this demand in the short term. The biggest alternative to that gas generation that we would need in the next couple of years is renewables.”
