China’s car industry has been on a tear lately. Last year, China became the world’s largest auto exporter, and its home-grown carmaker BYD recently eclipsed Tesla as the world’s No. 1 maker of electrified vehicles.
If China were following a playbook first written by Japanese or Korean automakers, you’d expect them to start selling their cars in the United States pretty soon. But China — unlike Japan or South Korea — is not an American ally, and so it’s going to have to follow a different path.
On Thursday, the Biden administration opened an investigation into the national security risks posed by Chinese-made “connected vehicles,” which essentially means any vehicle or any car part that connects to the internet. New cars, especially EVs, are outfitted with cameras, sensors, or cellular modems required for modern safety features.
The probe is the first part of what is likely to be a broad American policy response to the rise of Chinese electric vehicles. “China’s policies could flood our market with its vehicles, posing risks to our national security,” President Joe Biden said in a statement. “I’m not going to let that happen on my watch.”
The investigation is a big deal, in part because it marks that the backlash to Chinese EVs has begun in earnest in the U.S. Look closely and you’ll see Biden’s quote this morning gives away the game: Is the risk that Chinese vehicles flood the market, or is the risk that they’ll harm national security? For this administration, one has the sense that it’s both.
In a press briefing with reporters, Commerce Secretary Gina Rainmondo, whose office will lead the investigation, argued that these sensors and computers could pose a risk to national security.
“Imagine if there were thousands, or hundreds of thousands, of Chinese connected vehicles on American roads that could be immediately and simultaneously disabled by somebody in Beijing,” she said. “It doesn’t take a lot of imagination to figure out how a foreign adversary like China with access to this sort of information at scale could pose a serious risk for national security and the privacy of U.S. citizens.”
It was crucial to launch the investigation now, she added, before Chinese-made vehicles became more prevalent on American roads. Today, only a handful of brands — including Volvo, Polestar, and Buick — sell Chinese-made vehicles in the United States, and no Chinese-originating brand sells cars here.
There are three more things to observe about the sudden American action against Chinese EVs.
First, the administration’s actions aren’t particularly surprising. As I’ve previously written, the rise of Chinese EVs poses an existential threat to the legacy American automakers, including Ford and General Motors. These companies employ four times more workers in Michigan than in any other state, and Biden’s path to reelection runs straight through Michigan this November.
And even though Biden’s climate agenda has been aggressively focused on domestic development — you could argue that the Inflation Reduction Act is as much about national competitiveness as emissions reductions, per se — Donald Trump will claim no matter what that Biden’s climate policy is a “job-killing” gift to China. So Biden has to be especially certain that Chinese-made EVs don’t threaten — can’t even seem like a threat — to the Michigan auto industry.
Democrats, too, are not alone in calling for action against Chinese EV makers. Republicans have already branded Biden’s pro-EV campaign as a giveaway to China. On Wednesday, Senator Josh Hawley, a far-right Missouri Republican, proposed legislation that would raise tariffs on Chinese EVs much higher than their current level — to an astounding 125%. That would exceed the highest tariff rates on the books, and it would also apply the duties to Chinese-branded EVs made anywhere in the world, including in countries that the U.S. has a free-trade agreement with.
Second, the investigation reflects just how difficult it will be for the United States and China to keep from fighting over their highest quality technological exports. Over the past few years, the U.S. has targeted or restricted Huawei devices and the social network TikTok. China has slapped rules on how Apple’s and Tesla’s products can be used.
At Heatmap, we have written frequently about how the effort to deploy green technologies is becoming inseparable from geopolitics. But this fight is over something much broader than zero-carbon technologies — it’s potentially about digitized products, anything with software, which includes electric vehicles and batteries as well as smartphones and gadgets. If the American government now believes that Chinese-made products with cameras or sensors risk U.S. national security, then potentially a whole range of products — robot vacuums, e-bikes, GPS watches, even home appliances — could pose some sort of security risk. Electric vehicles may represent a greater security risk, but the difference between them and, say, phones is one of degrees and not kind.
Finally, the investigation reveals something that canny observers have already noted: Tariffs alone probably can’t keep Chinese-branded EVs out of the American market forever. BYD, the world’s No. 1 seller of electrified vehicles, is planning to open a factory in Mexico; it already sells its cars there. If BYD succeeds in establishing a North American beachhead, then its cars could potentially fall under U.S.-Mexico-Canada Trade Agreement rules and freely enter the United States. (The Hawley bill would theoretically circumvent this by applying its tariffs to Chinese-branded vehicles wherever they are made. Whether this would actually be worth the rift it would open with one of our most important manufacturing partners is an open question.)
Those vehicles could rapidly become the most affordable new cars on the road — if not in the United States itself, then in Mexico and Canada, where American brands compete. BYD recently advertised an $11,000 plug-in hybrid targeted at the Chinese market. Even if meeting American highway safety regulations added another $4,000 to that vehicle’s cost, it would still be among the cheapest new cars sold in this country. Even doubling its price with tariffs would keep it firmly among the country’s most affordable new vehicles.
That could be good. Electric vehicles need to get cheaper everywhere, including the U.S., if we are to fight climate change. Likewise, the Commerce Department’s investigation could result in a happy outcome, by which the national security and privacy risks of Chinese EVs could be managed — through software, for instance — allowing BYD or Polestar to sell some cars here without exposing Americans to significant risk. But that’s not the the direction that I expect things to take.

Current conditions: The remnants of Tropical Storm Chantal will bring heavy rain and potential flash floods to the Carolinas, southeastern Virginia, and southern Delaware through Monday night • Two people are dead and 300 injured after Typhoon Danas hit Taiwan • Life-threatening rainfall is expected to last through Monday in Central Texas.

The flash floods in Central Texas are expected to become one of the deadliest such events in the past 100 years, with authorities updating the death toll to 82 people on Sunday night. Another 41 people are still missing after the storms, which began Thursday night and raised the Guadalupe River some 26 feet in less than an hour, providing little chance for holiday weekend campers and RVers to escape.
Although it’s far too soon to definitively attribute the disaster to climate change, a warmer atmosphere is capable of holding more moisture and producing heavy bursts of life-threatening rainfall. Disasters like the one in Texas are one of the “hardest things to predict that’s becoming worse faster than almost anything else in a warming climate, and it’s at a moment where we’re defunding the ability of meteorologists and emergency managers to coordinate,” Daniel Swain of the University of California Agriculture and Natural Resources told the Los Angeles Times. Meteorologists who spoke to Wired argued that the National Weather Service “accurately predicted the risk of flooding in Texas and could not have foreseen the extreme severity of the storm” ahead of the event, while The New York Times noted that staffing shortages at the agency following President Trump’s layoffs potentially resulted in “the loss of experienced people who would typically have helped communicate with local authorities in the hours after flash flood warnings were issued overnight.”
President Trump announced this weekend that his administration plans to send up to 15 letters on Monday to important trade partners detailing their tariff rates. Though Trump didn’t specify which countries would receive such letters or what the rates could be, he said the tariffs would go into effect on August 1 — an extension from the administration’s 90-day pause through July 9 — and range “from maybe 60% or 70% tariffs to 10% and 20% tariffs.” Treasury Secretary Scott Bessent added on CNN on Sunday that the administration would subsequently send an additional round of letters to 100 less significant trade partners, warning them that “if you don’t move things along” with trade negotiations, “then on August 1, you will boomerang back to your April 2 tariff level.” Trump’s proposed tariffs have already rattled industries as diverse as steel and aluminum, oil, plastics, agriculture, and bicycles, as we’ve covered extensively here at Heatmap. Trump’s weekend announcement also sent jitters through global markets on Monday morning.
President Trump’s gutting of the Inflation Reduction Act with the signing of the budget reconciliation bill last week will add an extra 7 billion tons of emissions to the atmosphere by 2030, a new analysis by Climate Brief has found. The rollback on renewable energy credits and policy means that “U.S. emissions are now set to drop to just 3% below current levels by 2030 — effectively flatlining — rather than falling 40% as required to hit the now-defunct [Paris Agreement] target,” Carbon Brief notes. As a result, the U.S. will be about 2 billion tons short of its emissions goal by 2030, adding an emissions equivalent of “roughly the annual output of Indonesia, the world’s sixth-largest emitter.”
To reach its conclusions, Carbon Brief utilized modeling by Princeton University’s REPEAT Project, which examined how the current obstacles facing U.S. wind and solar energy will impact U.S. emissions targets, as well as the likely slowdown in electric vehicle sales and energy efficiency upgrades due to the removal of subsidies. “Under this new set of U.S. policies, emissions are only expected to be 20% lower than 2005 levels by 2030,” Carbon Brief writes.
Engineering giant SKF announced late last week that it had set a new world record for tidal turbine reliability, with its systems in northern Scotland having operated continuously for over six years at 1.5 megawatts “without the need for unplanned or disruptive maintenance.” The news represents a significant milestone for the technology since “harsh conditions, high maintenance, and technical challenges” have traditionally made tidal systems difficult to implement in the real world, Interesting Engineering notes. The pilot program, MayGen, is operated by SAE Renewables and aims, as its next step, to begin deploying 3-megawatt powertrains for 30 turbines across Scotland, France, and Japan starting next year.
Satellites monitoring the Southern Ocean have detected for the first time a collapse and reversal of a major current in the Atlantic Meridional Overturning Circulation. “This is an unprecedented observation and a potential game-changer,” said physicist Marilena Oltmanns, the lead author of a paper on the finding, adding that the changes could “alter the Southern Ocean’s capacity to sequester heat and carbon.”
A breakthrough in satellite ocean observation technology enabled scientists to recognize that, since 2016, the Southern Ocean has become saltier, even as Antarctic sea ice has melted at a rate comparable to the loss of Greenland’s ice. The two factors have altered the Southern Ocean’s properties like “we’ve never seen before,” Antonio Turiel, a co-author of the study, explained. “While the world is debating the potential collapse of the AMOC in the North Atlantic, we’re seeing that the Southern Ocean is drastically changing, as sea ice coverage declines and the upper ocean is becoming saltier,” he went on. “This could have unprecedented global climate impacts.” Read more about the oceanic feedback loop and its potential global consequences at Science Daily, here.
The French public research university Sciences Po will open the Paris Climate School in September 2026, making it the first school in Europe to offer a “degree in humanities and social sciences dedicated to ecological transition.” The first cohort will comprise 100 master’s students in an English-language program. “Faced with the ecological emergency, it is essential to train a new generation of leaders who can think and act differently,” said Laurence Tubiana, the dean of the Paris Climate School.
A fifth of U.S. counties now restrict renewables development, according to exclusive data gathered by Heatmap Pro.
A solar farm 40 minutes south of Columbus, Ohio.
A grid-scale battery near the coast of Nassau County, Long Island.
A sprawling wind farm — capable of generating enough electricity to power 100,000 homes — at the northern edge of Nebraska.
These projects — and hundreds of others — will never get built in the United States. They were blocked and ultimately killed by a regulatory sea-change that has reshaped how local governments consider and approve energy projects. One by one, counties and municipalities across the country are passing laws that heavily curtail the construction of new renewable power plants.
These laws are slowing the energy transition and raising costs for utility ratepayers. And the problem is getting worse.
The development of new wind and solar power plants is now heavily restricted or outright banned in about one in five counties across the country, according to a new and extensive survey of public records and local ordinances conducted by Heatmap News.
“That’s a lot,” Nicholas Bagley, a professor at the University of Michigan Law School, told us. Bagley said the “rash of new land use restrictions” owes partly to the increasing politicization of renewable energy.
Across the country, separate rules restrict renewables construction in 605 counties. In some cases, the rules greatly constrain where renewables can be built, such as by requiring that wind turbines must be placed miles from homes, or that solar farms may not take up more than 1% of a county’s agricultural land. In hundreds of other cases, the rules simply forbid new wind or solar construction at all.
Even in the liberal Northeast, where climate concern is high and municipalities broadly control the land use process, the number of restrictions is rising. At least 59 townships and municipalities have curtailed or outright banned new wind and solar farms across the Northeast, according to Heatmap’s survey.
Even though America has built new wind and solar projects for decades, the number of counties restricting renewable development has nearly doubled since 2022.
When the various state, county, and municipality-level ordinances are combined, roughly 17% of the total land mass of the continental United States has been marked as off limits to renewables construction.
These figures have not been previously reported. Over the past 12 months, our energy intelligence platform Heatmap Pro has conducted what it believes to be the most comprehensive survey of county and municipality-level renewables restrictions in the United States. In part, that research included surveys of existing databases of local news and county laws, including those prepared by the Sabin Center for Climate Change Law at Columbia University.
But our research team has also called thousands of counties, many of whose laws were not in existing public databases, and we have updated our data in real time as counties passed ordinances and opposed projects progress (or not) through the zoning process. This data is normally available to companies and individuals who subscribe to Heatmap Pro. In this story, we are making a high-level summary of this data available to the public for the first time.
Restrictions have proliferated in all regions of the country.
Forty counties in Virginia alone now have an anti-renewable law on the books, effectively halting solar development in large portions of the state, even as the region experiences blistering electricity load growth.
These anti-solar laws have even begun to slow down energy development across the sunny Southwest. Counties in Nevada and Arizona have rejected new solar development in the same parts of the state that have already seen a high number of solar projects, our data show. Since President Trump took office in January, the effect of these local rules have become more acute — while solar developers could previously avoid the rules by proposing projects on federal land, a permitting slowdown at the Bureau of Land Management is now styming solar projects of all types in the region, as our colleague Jael Holzman has reported.
In the Northeast and on the West Coast, where Democrats control most state governments, towns and counties are still successfully fighting and cancelling dozens of new energy projects. Battery electricity storage systems, or BESS projects, now draw particular ire. The high-profile case of the battery fire in Moss Landing, California, in January has led to a surge of local opposition to BESS projects, our data shows. So far in 2025, residents have cited the Moss Landing case when fighting at least six different BESS projects nationwide.
That’s what happened with Jupiter Power, the battery project proposed in Nassau County, Long Island. The 275-megawatt project was first proposed in 2022 for the Town of Oyster Bay, New York. It would have replaced a petroleum terminal and improved the resilience of the local power grid.
But opposed residents began attending public meetings to agitate about perceived fire and environmental risks, and in spring 2024 successfully lobbied the town to pass a six-month moratorium on battery storage systems. The developer of the battery storage system, Jupiter Power, announced it would withdraw after the town passed two consecutive extensions to the moratorium and residents continued agitating for tighter restrictions.
That pattern — a town passes a temporary moratorium that it repeatedly extends — is how many projects now die in the United States.
The Nebraska wind project, North Fork Wind, was effectively shuttered when Knox County passed a permanent wind-energy ban. And the solar project south of Columbus, Ohio? It died when the Ohio Power Siting Board ruled that “that any benefits to the local community are outweighed by public opposition” to the project, which would have generated 70 megawatts, enough to power about 9,000 homes.
The developers of both of these projects are now waging lengthy and expensive legal appeals to save them; neither has won yet. Even in cases where the developer ultimately prevails against a local law, opposition can waste years and raise the final cost of a project by millions of dollars.
Our Heatmap Pro platform models opposition history alongside demographic, employment, voting, and exclusive polling data to quantify the risk a project will face in every county in the country, allowing developers to avoid places where they are likely to be unsuccessful and strategize for those where they have a chance.
Access to the full project- and county-level data and associated risk assessments is available via Heatmap Pro.
And more on the week’s biggest conflicts around renewable energy projects.
1. Jackson County, Kansas – A judge has rejected a Hail Mary lawsuit to kill a single solar farm over it benefiting from the Inflation Reduction Act, siding with arguments from a somewhat unexpected source — the Trump administration’s Justice Department — which argued that projects qualifying for tax credits do not require federal environmental reviews.
2. Portage County, Wisconsin – The largest solar project in the Badger State is now one step closer to construction after settling with environmentalists concerned about impacts to the Greater Prairie Chicken, an imperiled bird species beloved in wildlife conservation circles.
3. Imperial County, California – The board of directors for the agriculture-saturated Imperial Irrigation District in southern California has approved a resolution opposing solar projects on farmland.
4. New England – Offshore wind opponents are starting to win big in state negotiations with developers, as officials once committed to the energy sources delay final decisions on maintaining contracts.
5. Barren County, Kentucky – Remember the National Park fighting the solar farm? We may see a resolution to that conflict later this month.
6. Washington County, Arkansas – It seems that RES’ efforts to build a wind farm here are leading the county to face calls for a blanket moratorium.
7. Westchester County, New York – Yet another resort town in New York may be saying “no” to battery storage over fire risks.
