U.S. EV sales have been way up — just not for the domestic champion, which sank to its worst-ever market share in August.
Using more electricity when it’s cheap can pay dividends later.
One of the best arguments for electric vehicles is the promise of lower costs for the owner. Yes, EVs cost more upfront than comparable gas-powered cars, but electric cars are cheaper to fuel and should require less routine maintenance, too. (Say goodbye to the 3,000-mile oil change.)
What about the societal scale, though? As the number of EVs on the road continues to rise, more analysts are putting forth the argument that EV ownership could lead to lower energy bills for everyone, even the people who don’t buy them.
The idea may be counterintuitive, given the prevailing narrative about voracious appetite for electricity. EVs do require a lot of energy. Electricity demand for EVs in the U.S. jumped 50% from 2023 to 2024 alone as more Americans bought electric, and the research group Ev.energy says demand could triple by 2030. Studies suggest that replacing every internal combustion vehicle in the country with an EV would eat up as much as 29% of American electricity.
Meanwhile, the grid is struggling to keep up — it is, after all, much more difficult to add more megawatts to the capacity of our power system than it is to put a few more EVs on the road. The obvious inference would then seem to be that a battery-powered car fleet could cause an energy crunch and spike in prices.
A new report from Ev.energy, however, argues that if we got smarter about how and when we charge our cars, their presence could actually cut costs for the average American by 10%. The gains could be even better if EVs reach their true potential as a way to give the grid a unique kind of flexibility and resilience.
Compare an electric car to a data center, the other application painted as a ticking time bomb for electricity prices. Worries about the energy-gobbling habits of AI-powering servers are well-founded, given their 24/7 appetite. An EV, however, needs to charge only once in a while. In fact, most people don’t need to charge every day, given the range of modern EVs and the driving habits of the typical American.
As we've covered before, it’s when you charge that matters. Optimizing EV charging can be a helpful way to ease pressure on the power grid and align EV charging with the availability of clean energy.
Here in California, which has far and away the most EVs in America, TV commercials remind us to use less energy between 4 p.m. and 9 p.m., when the state is dealing with rising residential energy use just as solar power is tapering off for the day. It would cause a grid crisis if every EV owner charged as soon as they got home from work. Having EV owners charge their cars overnight, a period of low demand, helps ease the pressure. So does charging during midday, when California sometimes has more solar energy than it knows what to do with.
When EVs charge in this mindful manner, using energy during times of day when it’s cheap for utilities to provide it, data suggests they can effectively push down electricity prices for everyone. Says one recent report from Synapse Energy: “In California, EVs have increased utility revenues more than they have increased utility costs, leading to downward pressure on electric rates for EV-owners and non-EV owners alike.” As the NRDC points out, California has revenue decoupling in place for its utilities, so “any additional revenue in excess of what was anticipated is returned to all utility customers — not just EV drivers — in the form of lower rates.”
Those rosy figures depend upon drivers following this model and charging during off-peak hours, of course. But with time-of-use rates giving them the financial motivation to charge overnight rather than in the early evening, it’s not an outrageous presumption.
And there’s something else that differentiates EVs from other applications that consume lots of electricity: Thanks to their ability to store a large number of kilowatt-hours over a lengthy period of time, electric vehicles can give back. EVs can be a cornerstone of the virtual power plant model because the cars — those equipped with bidirectional charging capabilities, at least — could feed the energy in their batteries back onto the grid to prevent blackouts, for example. In Australia, the Electric Vehicle Council recently crunched the numbers to argue in favor of incentivizing residents to install vehicle-to-grid infrastructure. Their math indicates Australia would reap more than the government invests because these connected EV would cut everyone’s electricity price.
It’s getting more expensive for the individual to own an EV — the federal tax credit for buying one disappears at month’s end, and punitive yearly fees for EV ownership are coming. Yet it seems that driving electric might be doing your neighbors a favor, and not just by clearing the air.

The Trump administration’s plan to kill a $20 billion clean energy financing program got the green light from a federal appeals court on Tuesday. The Greenhouse Gas Reduction Fund, housed under the Environmental Protection Agency, was designed to provide low-cost loans for solar installations, building efficiency upgrades, and other local efforts to reduce planet-heating emissions. The three-judge panel overturned a lower court’s injunction temporarily requiring the EPA to resume payments, ruling that most of the plaintiffs’ claims were contract disputes and belonged in the Court of Federal Claims. If the case now moves to that court, Heatmap’s Emily Pontecorvo wrote, “the plaintiffs would only be able to sue for damages and any possibility of reinstating the grants would be gone.”
Before leaving office, the Biden-era EPA finalized awards to eight nonprofits that would “create a national financing network for clean energy and climate solutions across the country.” The move was meant to insulate the program from cuts, but it stirred the new administration’s ire. The Trump EPA called the move a scam to give taxpayer-funded slush funds to nonprofits stacked with former Biden administration appointees. The recipients could still appeal the decision, which experts told Emily could still have significant ramifications. Watch this space.
The country’s largest electrical grid, the PJM Interconnection, put out a conceptual proposal in August for a plan to ask large electricity users such as data centers to voluntarily reduce their power consumption when there’s a shortage of electrons on the grid — and potentially require them to do so if too few step up. The plan is largely in line with what the Data Center Coalition, a trade association representing server companies, recently backed in a legal filing in North Carolina, as this newsletter previously reported. Yet big tech companies balked at the proposal, according to comments submitted in response. Microsoft warned that imposing curtailment undermines investor confidence. Amazon said targeting large power users to cut back on demand is discriminatory. Talen Energy, an independent power producer, said the 13-state-spanning PJM has no authority to make such a rule, and that individual state law governs load. The Data Center Coalition itself criticized the rule’s assumption that big power users have on-site back-up generation as overly broad and not reflective of reality.
The idea itself derives from an influential paper released by Duke University researchers in February that found the U.S. could add gigawatts’ worth of additional demand from new data centers without building out an equivalent amount of power plants if those facilities could curtail electricity usage when demand was particularly high. Heatmap’s Matthew Zeitlin described the strategy as “one weird trick for getting more data centers on the grid,” boiling down the approach simply as: “Just turn them off sometimes.”

The Trump administration said it would reconsider the permit for SouthCoast Wind, a Massachusetts offshore wind farm approved last year by the Biden administration, according to legal filings seen by Reuters on Tuesday. In a motion filed to the U.S. District Court for the District of Columbia on Friday, lawyers at the Department of Justice said the Department of the Interior would review the project’s construction and operations plan.
The move came a week after Trump yanked back approvals for the nearly-complete Revolution Wind project off Rhode Island’s coast. It’s just the latest escalation in what Heatmap’s Jael Holzman called “Trump’s total war on wind.” As I reported yesterday in this newsletter, the Department of Transportation was the most recent agency to join the effort this week, axing $679 million in funding for infrastructure to support offshore wind development. But the Interior Department has led the charge with a witch hunt against policies that favor wind power, the de-designation of millions of acres of federal waters for offshore turbine construction, and a new investigation into bird deaths near windmills. The Department of Commerce tapped in last month by teeing up future tariffs with its own probe into whether imported turbine components pose a national security threat. The assault is prompting pushback. On Monday, the Democratic governors of five Northeastern states called on Trump to “uphold all offshore wind permits already granted.”

In spite of Trump administration pressure aimed at convincing countries around the world to reject Russian oil, the Kremlin netted an energy deal with the world’s second-most populous nation on Tuesday in a sign of what Russian President Vladimir Putin called an “unprecedentedly high level” of good relations between Moscow and Beijing. Under the new agreement, China will buy Russian gas through a new pipeline from Siberia. Once complete, the Power of Siberia 2 pipeline will carry 50 billion cubic meters of gas through Mongolia to northern China every year.
The deal came at the tail end of a summit in China between Putin, Chinese President Xi Jinping, and Indian Prime Minister Narendra Modi. The trio of hardline leaders, who represent the three biggest economies in the world, came together for a photo depicting a friendly three-way handshake widely interpreted as a show of unity and defiance against Washington’s attempts to impose its will through economic sanctions.
The Tennessee Valley Authority is broadening its effort to remake itself as the testing ground for new American small modular reactors. On Tuesday, the federally-owned utility announced plans to buy 6 gigawatts of reactors from NuScale Power, the first and only SMR developer whose design has won approval from the Nuclear Regulatory Commission. Shares of NuScale — which has struggled since the high-profile failure of what was supposed to be the nation’s debut SMR power plant in Utah two years ago — surged nearly 8%.
The TVA had already planned to build the first U.S. units of GE Vernova-Hitachi Nuclear Energy’s 300-megawatt reactors, and last month became the country’s first utility to sign a power purchase agreement with a fourth-generation reactor developer, the Google-backed Kairos Power. The deals come amid what Heatmap’s Katie Brigham called a “nuclear power dealmaking boom.” On Tuesday an industrial standard-setting group that includes Exxon Mobil, Chevron, Shell, Rio Tinto, and IBM launched a new consortium to streamline processes around building advanced nuclear reactors. On Wednesday, Kairos inked a deal with nuclear fuel producer BWXT to work together on producing the rare type of uranium fuel the reactor company needs for its plants.
Wind turbines are notoriously not always recyclable. But they are reusable. Just ask Jos de Krieger, the co-founder of a Dutch company called Blade Made that purchases used turbines and transforms them into sleek, minimalist tiny homes. “Everything in the built environment — everything that you see around you — has an end of life,” Krieger told CNN. “And we need solutions besides waste or landfill, incineration or something without value… Changing that perception is really something that has to happen in the eyes of everyone,” he added, calling for “processes that create stories, instead of waste.”
