Any EV is better for the planet than a gas-guzzler, but size still matters for energy use.
A few Super Bowls ago, when General Motors used its ad spots to pitch Americans on the idea of the GMC Hummer EV, it tried to flip the script on the stereotypes that had always dogged the gas-guzzling SUV. Yes, it implied, you can drive a military-derived menace to society and still do your part for the planet, as long as it’s electric.
You don’t hear much about the Hummer anymore — it didn’t sell especially well, and the Tesla Cybertruck came along to fill the tank niche in the electric car market. But the reasoning behind its launch endures. Any EV, even a monstrous one, is a good EV if it convinces somebody, somewhere, to give up gasoline.
This line of thinking isn’t wrong. A fully electric version of a big truck or SUV is far better, emissions-wise, than a gas-powered vehicle of equivalent size. It’s arguably superior to a smaller and efficient combustion car, too. A Ford F-150 Lightning, for example, scores nearly 70 in the Environmental Protection Agency’s miles per gallon equivalent metric, abbreviated MPGe, that’s meant to compare the energy consumption of EVs and other cars. That blows away the 20-some miles per gallon that the gas F-150 gets and even exceeds the 57 combined miles per gallon of the current Toyota Prius hybrid.
In terms of America’s EV adoption, then, we’ve come to see all EVs as being created equal. Yet our penchant for large EVs that aren’t particularly efficient at squeezing miles from their batteries will become a problem as more Americans go electric.
Big, heavy cars use more energy. This is how we worried about the greenness of cars back in the days before the EV: Needlessly enormous models such as the Ford Expedition and the Hummer H2 deserved to be shamed, while owning a fuel-sipping hybrid or a dinky subcompact was the height of virtue.
This logic has gotten a bit lost in the scale-up phase of electric vehicles going mainstream. We talk at length about EV sales and how fast their numbers are growing; we rarely talk about whether the EVs we buy are as energy-efficient as they could be. As a new white paper from the American Council for an Energy-Efficient Economy points out, though, getting more miles out of our EV batteries would save drivers money and reduce the strain on the grid that will come from millions of people charging their cars.
The simplest way to measure an EV’s fuel efficiency is to know how many miles it travels per kilowatt-hour of electricity. Popular crossovers like Tesla’s Model Y and Kia’s EV6 achieve a pretty-good 3.5 miles per kilowatt-hour. Look at bigger, heavier vehicles and you’ll see a major fall-off. InsideEVs found that Rivian’s R1S gets between 2.1 and 2.4 miles per kilowatt-hour. The hulking Hummer EV scores just 1.5, according to Motor Trend’s testing. The EPA’s MPGe data is another way to see the same story. The 60-some miles per gallon equivalent of an electric pickup like the Rivian R1T or Chevy Silverado EV crushes the mileage of petro trucks, but pales next to the 140-plus MPGe that an electric sedan from Hyundai or Lucid can claim. (Those EVs can deliver 4 or more miles per kilowatt-hour.)
Even modest gains in EV efficiency could cause beneficial ripple effects, the ACEEE says. Drivers who own a 3.5 miles per kilowatt-hour car would save hundreds of dollars on fuel annually compared to those whose vehicles get 2.5 miles per kilowatt-hour. More efficient cars should be less expensive, as well. Huge, inefficient EVs need to carry enormous batteries just to reach an adequate range, and the bigger the battery, the bigger the cost. Whereas a Model Y’s battery capacity ranges from 60 kilowatt-hours for standard range to 81 kilowatt-hours for long range, a Rivian’s runs from 92 to 141.5 kilowatt-hours. ACEEE calculates that the jump from 2.5 to 3.5 kilowatt-hours could shave nearly $5,000 from the cost of making a car because it would need so much less battery.
Making EVs more efficient would mean faster charging stops, too, since drivers wouldn’t need to cram so many kilowatt-hours into their batteries. It would ease demand for electricity, making it easier for the grid to keep pace with an electrifying society. But convincing Americans to buy smaller, more efficient vehicles has been an uphill battle for decades.
Earlier this summer, Ford CEO Jim Farley called for a return to smaller vehicles as more of the U.S. car fleet turns over to electric. Yet it was Ford that just a few years ago quit making cars altogether (outside of the Mustang) because it reaped so much more profit on the pricier crossovers, SUVs, and pickups that Americans have voted for with their wallets. And not long after Farley’s speech, the company scaled back its EV ambitions, clearly struggling to find a way to sell electric vehicles profitably.
The issue is not only carbuyers’ preference for big, heavy vehicles. ACEEE points out that public policy doesn’t punish big electric cars. “The EPA standard treats all EVs as having zero emissions. It therefore provides no incentive to improve EV efficiency since inefficient and efficient EVs are treated the same for compliance purposes,” the paper says.
That is why ACEEE floats the idea of a policy change. For example, its paper suggests the fees some states levy against EVs (ostensibly to make up for the lost revenue from those cars avoiding the gas tax) could be tweaked to charge more for inefficient EVs. Rebates for purchasing an EV could be changed in the same manner.
It was, after all, regulatory loopholes and misplaced incentives that helped big gas guzzlers conquer the roads in the first place. With better rules about big EVs, perhaps we could avoid repeating the mistakes of the past.

The state’s senior senator, Thom Tillis, has been vocal about the need to maintain clean energy tax credits.
The majority of voters in North Carolina want Congress to leave the Inflation Reduction Act well enough alone, a new poll from Data for Progress finds.
The survey, which asked North Carolina voters specifically about the clean energy and climate provisions in the bill, presented respondents with a choice between two statements: “The IRA should be repealed by Congress” and “The IRA should be kept in place by Congress.” (“Don’t know” was also an option.)
The responses from voters broke down predictably along party lines, with 71% of Democrats preferring to keep the IRA in place compared to just 31% of Republicans, with half of independent voters in favor of keeping the climate law. Overall, half of North Carolina voters surveyed wanted the IRA to stick around, compared to 37% who’d rather see it go — a significant spread for a state that, prior to the passage of the climate law, was home to little in the way of clean energy development.
But North Carolina now has a lot to lose with the potential repeal of the Inflation Reduction Act, as my colleague Emily Pontecorvo has pointed out. The IRA brought more than 17,000 jobs to the state, per Climate Power, along with $20 billion in investment spread out over 34 clean energy projects. Electric vehicle and charging manufacturers in particular have flocked to the state, with Toyota investing $13.9 billion in its Liberty EV battery manufacturing facility, which opened this past April.
North Carolina Senator Thom Tillis was one of the four co-authors of a letter sent to Majority Leader John Thune in April advocating for the preservation of the law. Together, they wrote that gutting the IRA’s tax credits “would create uncertainty, jeopardizing capital allocation, long-term project planning, and job creation in the energy sector and across our broader economy.” It seems that the majority of North Carolina voters are aligned with their senator — which is lucky for him, as he’s up for reelection in 2026.
The new Nissan Leaf is joining a whole crop of new electric cars in the $30,000 range.
Here is an odd sentence to write in the year 2025: One of the most interesting electric vehicles on the horizon is the Nissan Leaf.
The Japanese automaker last week revealed new images and specs of the redesign it had teased a few months ago. The new Leaf, which will arrive in 2026, is a small crossover that’s sleeker than, say, a Tesla Model Y, but more spacious than the previous hatchback versions of the car. Nissan promises it will have a max range above 300 miles, while industry experts expect the company to target a starting price not too far above $30,000.
The updated Leaf won’t be one of those EVs that smokes a gas-powered sports car in a drag race, not with the 214 horsepower from that debut version and certainly not with the 174 horsepower from the cheaper version that will arrive later on. Its 150-kilowatt max charging speed lags far behind the blazing fast 350-kilowatt charging capability Hyundai is building into its Ioniq electric vehicles. But because it lacks some of these refinements, the new Nissan may arrive as one of the most compelling of the “affordable” EVs that are, finally, coming to drivers.
Not bad for a car that had become an electric afterthought.
The original Nissan Leaf was a revelation merely for its existence. Never mind that it was a lumpy potato derived from the uninspired Nissan Versa — here was the first mass-market electric car, heralding the age of the EV and welcomed with plenty of “car of the year” laurels at the dawn of the 2010s. Its luster would not last, however, as the arrival of the Tesla Model S a couple of years later stole the world’s attention. The second-generation Leaf that arrived in 2017 was an aesthetic and technological leap forward from its predecessor, with a range that topped 200 miles in its most advanced form. It was, for the time, a pretty good EV. Almost immediately, it was overshadowed by the introduction of Tesla’s Model 3 and Model Y, which catapulted Elon Musk’s company into complete dominance of the global EV market.
It took nearly a decade for Nissan (which fell into corporate mismanagement and outright crisis in the meantime) to update the stale and outdated Leaf. As a result, you might think the new version of the OG EV will arrive just in time to be outshone again. Yet the peculiar nature of the evolving electric car market has created an opportunity for the Leaf to finally grow and thrive.
There was a time when the mythical affordable Tesla could have taken the brand into the entry-level car market, and perhaps below the magic starting price of $30,000. But that has turned out to be a distraction dangled in front of fanboys and investors. In reality, Musk effectively killed the idea as he instead rolled out the Cybertruck and pivoted the company toward the dream of total vehicle autonomy.
Thanks to Tesla’s refusal to act like a normal car company, the affordable EV market is still there for the taking. Some are already in the game: Hyundai’s little Kona Electric starts at $33,000, and I’ve lauded Chevrolet for building a base version of the Equinox EV that starts around $35,000. In the next year or so, an influx of EVs in the $30,000 to $35,000 range might really change the game for electric-curious buyers.
The new Leaf is suddenly a big part of that mix. No, it won’t compete on price with a comparable combustion Nissan like the Kicks crossover that starts in the low $20,000s (not without the $7,500 tax credit, which would have made the new crop of affordable EVs directly cost-competitive with entry-level gas cars). The Leaf is likely to start just above $30,000, with the price creeping higher for buyers who opt for better performance or more range (and as I’ve noted numerous times, you ought to buy all the range you can afford if an EV is going to be your main car).
Arriving next year to compete with the Leaf is the new Chevy Bolt, another revival of an early EV icon. Experts expect a similar price range there. The anticipated Kia EV3 should come to America eventually with a starting cost around $35,000. The Jeff Bezos-backed Slate electric truck shocked the world with its promise of a bare-bones EV in the $20,000s — but, by the time the average buyer adds enough amenities to make it liveable, most Slate trucks will probably top $30,000.
Elon Musk may have abdicated his role as the Leaf’s antagonist via his refusal to build an affordable car, but erstwhile ally Donald Trump is poised to assume the role. Since the Leaf is slated to be built in Japan, the EV would be subject to whatever tariffs might be in place by the time it goes on sale next year. A 25% tariff, plus the federal government’s flip to punishing EVs with penalties instead of rewarding them with incentives, would kill the car’s value proposition in the U.S. Perhaps, then, it will become the next great affordable EV — for everybody else.
On life-threatening temperatures, New York’s nuclear ambitions, and cancelled clean energy projects
Current conditions: Monsoon conditions are bringing flash floods to New Mexico • A heat warning has been issued in Beijing as temperatures creep toward 100 degrees Fahrenheit • It's hot and dry in Tehran today as a tenuous ceasefire between Iran and Israel comes into effect.
New York Governor Kathy Hochul announced on Monday that she wants to bring new, public nuclear power back to the state. She directed the New York Power Authority, the state power agency, to develop at least 1 gigawatt of new nuclear capacity upstate. Hochul did not specify a design or even a location for the new plant, but based on a few clues in the press release and where Hochul chose to make the announcement, Heatmap’s Matthew Zeitlin speculates that the project could be a small modular reactor, specifically GE Hitachi’s BWRX-300, one of a handful of SMR designs vying for both regulatory approval and commercial viability in the U.S. “Canada’s Ontario Power Generation recently approved a plan to build one,” Zeitlin notes, “with the idea to eventually build three more for a total 1.2 gigawatts of generating capacity, i.e. roughly the amount Hochul’s targeting.”
The announcement comes at a time when the federal regulatory and tax balance is tipping toward nuclear. The Trump administration issued a fleet of executive orders looking to speed up nuclear construction and regulatory approvals, and Senate Republicans’ version of the mega budget reconciliation bill includes far more generous treatment of nuclear development compared to wind and solar.
The heat dome that’s moving slowly across the U.S. is bringing dangerous conditions to millions of Americans. Multiple cities across the Midwest and East Coast felt hotter than 100 degrees Fahrenheit yesterday, including Chicago, Nashville, and Raleigh. Roads buckled in Missouri. In New York’s Staten Island, the heat index hit 113 degrees. “This is life-threatening,” NYC Emergency Management said in a post on X. “At this level, the human body struggles to cool itself. Prolonged exposure or physical activity can quickly lead to heat stroke.” Power outages were reported in parts of the city. New York Mayor Eric Adams urged residents to help relieve the strain on the electric grid by avoiding using large appliances in the middle of the day, turning off lights, and limiting unnecessary air conditioning use. Wholesale energy prices soared as use skyrocketed. According to AccuWeather, more than 160 daily high temperature records could fall this week before things cool down Wednesday. Nearly 150 million people are affected by some kind of heat alert, and about 10% of the nation’s population will endure temperatures at or above 100 degrees today.

About $1.4 billion in clean energy projects were cancelled last month as policy uncertainty mounts and the GOP’s budget reconciliation megabill hacks away at clean energy tax credits and permitting reform. According to a new report from clean energy business group E2, $15.5 billion in new factories and electricity projects have been nixed since the start of 2025, along with the 12,000 new jobs those projects were expected to create. “Republican congressional districts are losing the most,” the report finds. “More than $9 billion in investments and almost 10,000 jobs have been cancelled, delayed, or closed in Republican districts so far in 2025.”
The world added 741 gigawatts of renewable energy capacity last year, according to the new Renewables Global Status Report from Paris-based think tank REN21. That’s a new record, but it still falls far short of the COP28 goal to triple renewables capacity by 2030. In fact, “current trajectories suggest a shortfall of 6.2 terawatts – more than all renewables deployed to date,” the report finds. Here are some other key takeaways:

The Trump administration will roll back protections for nearly 60 million acres of pristine national forest, Agriculture Secretary Brooke Rollins announced Monday. Rescinding the 2001 “Roadless Rule” will open vast swathes of the nation’s forests — including Tongass National Forest in Alaska, which is North America’s largest temperate rainforest — to industrial activities. The administration called the rule “overly restrictive,” and said rolling it back will allow for better fire prevention and “responsible” timber production. The logging industry applauded the announcement; conservation groups condemned it. The rollback is likely to be challenged in court.
“I now believe that cleaning up methane leaks from the production and shipping of oil and gas — one of the most significant sources of these emissions — is the best hope we have to avoid triggering some of the most consequential climate tipping points in the next decade. I think realistically it is our only hope.” –Carl Pope, former executive director of the Sierra Club, on his biggest regrets as an environmentalist.
