Do you want a light tailwind or a full-on hurricane?

“The only thing better for the climate than buying an EV over a gasoline-powered car is buying no car at all,” the climate scientist
Rob Jackson has written. But for many Americans, not having a car at all is the stuff of logistical and cultural nightmares. The average person living in the U.S. covers more than 1,000 miles per month in their vehicle, and nearly 45% of people don’t even have the option of opting for public transportation. Ditching your car? You might as well ask people to give up their cell phones.
But across the country, transportation advocates and e-bike warriors are looking for solutions to go, if not entirely car-less, then at least car-light. Heatmap has put together a comprehensive guide to help you make a decision that best fits your lifestyle, whether that’s becoming a superpedestrian, a committed e-bike user, or just trying to replace a couple of short-haul drives a week.
Doug Gordon is the cohost of “The War on Cars,” a podcast about the fight against car culture. He is also a writer, TV producer, and safe streets advocate, and he advises nonprofits and mobility companies on communications strategies to promote better streets and public infrastructure through his Brooklyn Spoke Media consulting business.
Alexa Sledge is the director of communications at Transportation Alternatives, a nonprofit organization that has worked to promote non-polluting, safe, and quiet travel in New York City since 1973.
Bryan Dean is the sales manager at The eBike Store in Portland, Oregon, which opened in 2008 as the city’s first e-bike-only retailer. He’s spent over six years helping customers pick out their perfect bikes and is also the creator of the #eBikeAnywhere hashtag.
Kevin Lau is a product specialist at REI with more than 20 years of experience. He is based out of Marlton, New Jersey.
Only 8% of U.S. households currently get by without owning a car, and less than 1% of Americans commute to work by bike. The U.S. is so driving-centric that we’re home to one-fifth of all the cars on the planet despite having less than 5% of the global population. Eleven states have more registered vehicles than people.
But just because driving has always been your default doesn’t mean it makes the most sense for the kind of travel you do — even if you live somewhere without great public transportation. Over half of all trips Americans make in a car are for a distance of less than three miles — perfect to convert into a bike ride.
“I think of mobility like a Swiss army knife: You have to use the right tool for the job,” Gordon told me. “If I just need to pick up a carton of milk, does it make sense to do that in a 6,000-pound metal box on wheels that is powered by dinosaur juice? Not so much.”
On average, commuting by bike in the U.S. saves an estimated $2,500 per year, and it has been found to have massive benefits for one’s mental health, cardiovascular health, and even productivity at work. Yes, even e-bikes!
“If you go to places like Copenhagen or Amsterdam — places where there are huge numbers of cyclists — and you poll those people, concern for the environment barely cracks the top five reasons why they cycle,” Gordon said. “The reasons why people cycle in Denmark and the Netherlands are because it’s safe and convenient, and it’s often the fastest and cheapest way to get where they’re going.”
Transportation is the most significant contributor to climate change in the United States, with nearly 60% of the sector’s greenhouse gas emissions coming from cars alone (another 23% comes from trucks). Replacing a quarter of your total driving with walking, biking, or e-biking could save 1.3 tons of greenhouse gas emissions per year, according to our friends at WattTime — about the same as forgoing burning 1,433 pounds of coal or three barrels of oil. If every American drove even a mere 10% less per year, it’d be like taking 28 coal-fired power plants offline.
You can still make a significant impact without ditching your car, in other words: You simply have to drive less. And the upsides are enormous. More Americans die of car pollution than in car accidents every year. Additionally, commuting by bike or by foot makes us healthier and happier.
It also helps us realize what our community priorities should be. “Individual action is not always what we need to focus on,” Gordon said. “We need to focus on institutional change. But my philosophy is that lots of individual action actually adds up to the political will to get the institutional change you need.”
A survey of studies from five countries (including the U.S.) found that the main barriers to cycling were low perceived safety, bad weather, lack of cycling infrastructure (including “shower facilities” at one’s destination), and distance and perceived effort.
Safety is a valid concern. Riding a bike is about 500 times more likely to be fatal than riding a bus, according to a 2007 study; even with the success of programs like New York’s Vision Zero, collisions with cars remain a real danger for people on bikes. The car-related pollution inhaled while cycling can also shorten a cyclist’s life by an estimated one to 40 days. But the benefits of cycling on average far outweigh the risks: Riding a bike adds an estimated three to 14 months to your life, even when the possibilities of collisions and air pollution are considered. The health benefits are so significant that a separate study by Swedish researchers found that cyclists had a 47% lower risk of early death and a 10% lower risk of hospitalization compared to car and train commuters.
What about concerns about shower availability and the “distance and perceived effort” of riding a bike? That’s where the advantages of an e-bike’s pedal assist come into play. “E-bikes are great at blasting through any concerns you have about sweat,” Gordon told me. Even in hot weather or on difficult terrain, pedal assist can keep you looking fresh when you arrive at the office.
The first step to driving less is thinking about when and where you can replace specific trips with walking, cycling, or public transportation instead. Lau told me his general rule of thumb is that if a trip is less than a mile and he can safely walk (i.e. if there are sidewalks or safe paths), then he’ll walk. “If it’s more than that, I’ll take the bike if I have a place to lock it or can bring it into my workplace or store,” he said. For trips where he might need some extra assistance — that are farther, longer, hillier, or will require carrying “more cargo without working as hard,” he’ll opt for an e-bike instead.
You can do a lot of this reconnaissance from your couch. Apple Maps and Google Maps can take a lot of the guesswork out of finding the best bike paths to and from your house and the other places you frequent, including informing you ahead of time if the route will require riding on major or minor roads or ones with protected bike lanes. Google and Apple Maps can also give you real-time information about public transportation options in your area (as well as allow you to plan for trips when service might be reduced, like late nights or weekends), and many transit systems now have their own apps to make tracking delays or alternative service simpler.
It’s funny how you don’t realize where the long, slow inclines are in your neighborhood until you’re huffing up them on a bike. Google Maps and Apple Maps can show you what elevation to expect on a walking or cycling route. If you live in a hillier area, an e-bike might be better than a traditional bike since it can take some of the ouch out of the ups.
“Something really, really important that people don’t always think about is gear,” Sledge told me. “It doesn’t necessarily have to be expensive, but if you can only ride your bike when it’s 80 degrees and sunny, that’s not the best scenario.”
If you live somewhere where it gets hot, rainy, snowy, windy, or the weather can change unexpectedly, think ahead of time about the sort of gear you’d need to make cycling or walking more comfortable. (We have a checklist of ideas below.)
California, Colorado, Connecticut, Hawaii, Massachusetts, New York, Oklahoma, and Vermont all have statewide tax credits or rebates to encourage e-bike adoption.
Live somewhere that isn’t on that list? Here is a super handy tracker from the Transportation Research and Education Center at Portland State University of more than 100 counties, cities, and municipalities that offer e-bike incentive programs. Also, look for e-bike lending libraries that might be in your area.
If you’re having trouble learning about the programs available to you, head into a brick-and-mortar e-bike shop in your area or connect with your local transportation advocacy group — they’ll know what programs you can take advantage of and be happy to point you in the right direction.
Do you know what bike enthusiasts love more than anything? Creating new bike enthusiasts. If you’re still feeling intimidated by the idea of getting on a bike — or even if you’re not — “find a friend who’s already doing it,” Gordon suggested. Bike people are “an evangelical bunch, and if you tell a friend who you know is into biking or bike commutes regularly that ‘Hey, I’m thinking of doing it,’ I can guarantee that person will be more than happy to hold your hand and help you through your first ride.”
There are dozens of emissions-free or emissions-light transportation options, from using your own two feet to digging the old beater bicycle out of your garage to going full Steve Wozniak with a Segway. The most important thing is to something you’ll actually use.
That said — “What’s really going to be the best option for most Americans is an e-bike,” Sledge told me. “That’s a true car replacement when so often a [traditional] bike can’t be a true, true, true car replacement.” E-bikes are simply more practical and comfortable for longer rides or daily commutes, and if you need to haul things like groceries or children, they can’t be beaten.
I’ve looked at all my options and don’t think I can drive any less than I already do. What can I do instead?
There’s no way around it: E-bikes are pricy. “An e-bike is going to be a big purchase — nowhere near as much as a car, but still, it’s a major purchase,” Sledge said. Even with incentive programs (more on that below), you’re likely to spend more than $1,000 out of pocket.
It is tempting to look for a bargain. But Dean stressed that manufacturers and bulk retailers are “sacrificing a lot” in terms of quality and service to make a profit at lower price points. As a rule, “If you’re spending less than $1,000 on any bike, it’s landfill,” he said. “And that waste is toxic — odds are, it isn’t going to be recycled properly.”
Gordon suggested that if you’re concerned about how often you’ll use an e-bike, it makes sense to get “a cheap regular bike” initially. “Then you can figure out if this is something you want to do in the long term, and after a few weeks, or a month, or a year, you can go, ‘Okay, I’m ready for the $1,000, $2,000, $5,000 bicycle.’”
Perspective is important, too. Yes, e-bikes are expensive — if you compare them to regular bikes. “If you compare them to cars, they’re a bargain,” Gordon said. “E-bikes are a replacement tool; they’re not an upgrade from other bikes. So if you’re a family with two cars and are going down to one, getting a $2,500 or even $5,000 e-bike is a relative bargain.” Additionally, many retailers — including The eBike Store in Portland, Oregon, where Dean works — offer installment plans to help make the purchase more manageable.
Conversion kits are a popular way to convert an analog bike you already own into an e-bike by attaching a motor to the front hub, rear hub, or mid-drive. Many of these kits can be found cheaply on websites like Amazon, though The Washington Post warns that it is still a “very Wild West market” and to only buy batteries from reputable e-bike battery brands (low-quality batteries are more likely to start fires). While converting to an e-bike might be a good option for you if you want to dip a toe in the e-bike water, you’ll still need to spend several hundred dollars to get a kit that gives you the same oomph as an actual e-bike. That said, whatever option gets you on a bike is the best one, and if you’re converter-kit curious, here’s a good guide for learning where to start.
“Buying a bike at a brick-and-mortar store from competent, kind people who love their job — customers are going to have a fantastic experience,” Dean told me. “They’re going to get a great taste for the bike, which means they’ll be riding it a lot. We’re not in the business of selling bikes that sit and rot in someone’s garage.”
It is especially important to go to a store with e-bike specialists on staff (rather than a bulk retailer like Costco — or worse, anything online) because the mechanics will have checked the bike over and adjusted the safety points so it’s ready to go. “You’re going to get educated and get a strong appreciation of the beautiful tool that you are buying, and learn how to operate it and make it last,” Dean added.
Most importantly, though, ensure you take the bike for a test ride before handing over your credit card. Any retailer worth its salt will offer this as an option; the best retailers will take you on a guided test ride, where they’ll teach you how to use the e-bike you’re trying out. But the bottom line is, “Don’t buy a bike that you haven’t ridden,” Dean said. “Ride the bike before you buy it; that’s in all-caps with smiley faces and exclamation points. Don't buy the bike if you can’t ride it first.”
“Buy the bike that’s going to put the biggest, dumbest smile on your face.”
Dean said he points riders looking to log miles to the Specialized Como. “When you’re commuting long miles, you want something comfortable, something that’s reliable, something that has a strong enough motor that will get you where you’re going and a big-enough battery that you’re not going to sweat it,” he said. The Specialized Como is also an excellent choice for people who want to “show up to work not sweaty” but maybe get a little bit more of a workout on the way home.
If you prefer commuting on a traditional bike, Lau suggested REI’s ADV 1.1, a road touring bike, or the CTY 1.1 bike, a less-expensive hybrid built for logging longer distances and enduring the daily wear-and-tear of a commute. His e-bike pick for commuters is the CTY e2.2, a popular, well-reviewed, and accessible commuter bike specifically marketed to “replace car trips.”
Dean loves to recommend Tern bikes to people who want to make trips with their kids. “They’ve been doing this for a long time, they have tons of great accessories, and they use Bosch power systems,” he said — all points in the bike’s favor. That customizability and reliability make it a good fit for families who want to be able to tailor the bike to their needs and price point while also not having to worry about it breaking down in the middle of a toddler’s meltdown.
But there is one other primary reason why Dean points parents to Tern. “All of their bikes are rider first, cargo behind” — versus bucket bikes that put the cargo in front of the rider. While the latter design is also popular, it also means that if you’re trying to squeak out into traffic, you’re nosing your most precious cargo ahead of you, into potential harm’s way.
Lau offered three options for e-bikes that won’t make you miss the trunk of your car, starting with the Cannondale Cargowagen, which can lug up to 440 pounds — that is a lot of Chili & Lime Flavored Rolled Corn Tortilla Chips. Its range isn’t quite as good as some other bikes on the market — the battery is 545 watt-hours — so it’s probably a better fit for people who live in higher-density areas or near their preferred market. (You can always buy a second battery if you want a little more range.) The Cargowagen is also a class 3 bike, meaning you won’t have to worry about the ice cream melting before you can get home.
Like Dean, Lau loves to recommend Tern bikes for handling heavy loads, especially the Tern GSD S00, which conveniently folds up so it can even be stored in an apartment or transported in an elevator while still being compatible with Tern’s line of cargo-carrying products — but at almost $6,000 before add-ons, it’ll likely be out of many first-time e-bikers’ budgets. Tern’s Vektron S10 is a less expensive option and still has the power to handle hilly roads with six Trader Joe’s bags in tow. (Note that both Terns are class 1 bikes, meaning the pedal assist tops out at 20 miles per hour.)
“Lightweight e-bikes are out there,” Dean said, and can be had — for the right amount of money. “They’re usually going to start around $3,500 to $4,000 and then go up from there,” he told me, pointing to Specialized as one of his favorite lightweight brands.
Keep in mind that you may not need a lightweight e-bike. “No one has ever come in and said, ‘I want a heavy bike,’” Dean pointed out. Electric motors are, by necessity, heavy, so getting a lighter bike can mean sacrificing half the motor and battery. There are workarounds: “If you have stairs to go up, almost all of these bikes have a walk assist mode,” which gently turns the tires so you’re not fighting gravity on your own, Dean told me. Likewise, if you’re trying to load your bike onto a car rack, “you don’t have to Hulk it up there; you can be a little smarter about your efforts by picking up the front wheel and putting it in the rack behind your car. Then pick up the back wheel.” If you’re really struggling with your bike, you can always pop off the battery — one of the heavier components — and carry it separately.
The best new commuter bike you can get away with is the CTY 1.1, the analog bike Lau recommended above, but for an e-bike option, he points customers to the Co-op CTY e2.1, an easy, accessible, no-frills class 1 bike that won’t run you more than $2,000. It might be a little light on features for a serious urban commuter, though.
Dean told me that the Gazelle Medeo and some of the bikes from Electra Country will have price points that could be more acceptable to customers on a budget. Gazelle uses the reliable Bosch power system, and the Medeo is “really good” and comes in “multiple versions.” (I found one for less than $2,000). Electra Country is a subsidiary of Trek and is a “one-size-fits-all, beach cruiser-looking bike” that comes in super fun colors.
Congratulations! You’re the proud owner of a bike or an e-bike (or skateboard or e-scooter or a really good pair of walking shoes). What happens now?
While the benefits of riding a bike (or any other form of active transportation) still outweigh the risks, cars are getting bigger, their blindspots are getting larger, and pedestrian and cyclist deaths nationwide are at a 40-year high. Even electric vehicles might be a small part of the problem since they’re so much heavier than regular cars — and that much more dangerous if you get hit.
I asked Sledge how newly carless commuters could become better pedestrians, and she quickly corrected me. “There is no such thing as being a good pedestrian,” she said. “So often, in the United States, when we have groups of people that are consistently harmed by other groups of people, we’re like, ‘How can the victims be better?’ And the real answer is, ‘How can we create systems and designs that protect those people?’”
We’ll get into that. But the bottom line is: be safe when you’re out on the road. Learn how to navigate intersections safely, and don’t take unnecessary risks. Especially if you’re on an e-bike, “You’re traveling faster than most cars are expecting you to,” Dean said. “To remember that, imagine you are not only invisible, but they’re all trying to kill you.”
“Riding a bike is a really good entry for a lot of people into larger political conversations about climate, the design of their cities or towns, and a host of other issues,” Gordon told me. It might only be a short amount of time before you start to wonder why there aren’t more protected bike lanes in your town or city, or why mass transit isn’t reaching your neighborhood or destination, or why lousy road design is making your commute more dangerous than it should be.
There’s some good news, though: There has never been a better time to become a transit advocate. “It could be as small as your block, or your neighborhood, or your city, but there are tons of groups all over the country that focus on working to make them safer and better for the people in them,” Sledge said.
One of the best places to start is by making your voice and your values heard. As Sledge reminded me, car companies already have — and continue to spend money and time lobbying policies that are better for drivers (and their bottom lines) than others on the road. But where to begin? “First, I would look for any kind of organization in your community, your neighborhood, or your city that focuses on safe streets or fighting climate change, and see if you can get involved with them,” Sledge said. “And if you don’t have that kind of organization, start to go to your city council meetings, making your voice heard with your local representatives — those kinds of things really make a difference.”
Another great resource is Transportation for America’s Transit Advocate Guide, which takes you step-by-step through building a movement in your community. Transportation Alternatives also hosts occasional activist trainings to help you learn how to organize successful campaigns in your neighborhood.
Maybe you bought an e-bike or a monthly metro pass … but you’ve been unable to quit your car the way you thought you would. That’s okay! This is not an all-or-nothing activity. “Don’t feel guilty if you’re still driving,” Gordon stressed. Remember that “you’re operating within a system that is built for you to drive, so starting small is really good.” Every fit and start of progress helps.
Remember also that better, low- and zero-emissions-friendly infrastructure and a pedestrian-first culture aren’t going to be built overnight. Even the most hard-core among us still need to use cars occasionally. Just “reimagining how we’re going to truly allocate our public resources — our public dollars, our public services — to serve everyone, and radically rethinking how to do that, is so important,” Sledge said.
I will leave you with one last instruction for ditching your car. When you discover the bike that lets you “follow your joy, follow your bliss,” and puts a “smile on your face” — as Dean likes to say — don’t keep it to yourself.
Someone else in your community is beginning to think about ditching their car, too. It’s your turn now. Go forth. Become someone else’s enthusiastic bike geek.

Citrine Informatics has been applying machine learning to materials discovery for years. Now more advanced models are giving the tech a big boost.
When ChatGPT launched three years ago, it became abundantly clear that the power of generative artificial intelligence had the capacity to extend far beyond clever chatbots. Companies raised huge amounts of funding based on the idea that this new, more powerful AI could solve fundamental problems in science and medicine — design new proteins, discover breakthrough drugs, or invent new battery chemistries.
Citrine Informatics, however, has largely kept its head down. The startup was founded long before the AI boom, back in 2013, with the intention of using simple old machine learning to speed up the development of more advanced, sustainable materials. These days Citrine is doing the same thing, but with neural networks and transformers, the architecture that undergirds the generative AI revolution.
“The technology transition we’re going through right now is pretty massive,” Greg Mulholland, Citrine’s founder and CEO, told me. “But the core underlying goal of the company is still the same: help scientists identify the experiments that will get them to their material outcome as fast as possible.”
Rather than developing its own novel materials, Citrine operates on a software-as-a-service model, selling its platform to companies including Rolls-Royce, EMD Electronics, and chemicals giant LyondellBassell. While a SaaS product may be less glamorous than independently discovering a breakthrough compound that enables something like a room-temperature superconductor or an ultra-high-density battery, Citrine’s approach has already surfaced commercially relevant materials across a variety of sectors, while the boldest promises of generative AI for science remain distant dreams.
“You can think of it as science versus engineering,” Mulholland told me. “A lot of science is being done. Citrine is definitely the best in kind of taking it to the engineering level and coming to a product outcome rather than a scientific discovery.” Citrine has helped to develop everything from bio-based lotion ingredients to replace petrochemical-derived ones, to plastic-free detergents, to more sustainable fire-resistant home insulation, to PFAS-free food packaging, to UV-resistant paints.
On Wednesday, the company unveiled two new platform capabilities that it says will take its approach to the next level. The first is essentially an advanced LLM-powered filing system that organizes and structures unwieldy materials and chemicals datasets from across a company. The second is an AI framework informed by an extensive repository of chemistry, physics, and materials knowledge. It can ingest a company’s existing data, and, even if the overall volume is small, use it to create a list of hundreds of potential new materials optimized for factors such as sustainability, durability, weight, manufacturability, or whatever other outcomes the company is targeting.
The platform is neither purely generative nor purely predictive. Instead, Mulholland explained, companies can choose to use Citrine’s tools “in a more generative mode” if they want to explore broadly and open up the field of possible materials discoveries, or in a more “optimized” mode that stays narrowly focused on the parameters they set. “What we find is you need a healthy blend of the two,” he told me.
The novel compounds the model spits out still need to be synthesized and tested by humans. “What I tell people is, any plane made of materials designed exclusively by Citrine and never tested is not a plane I’m getting on,” Mulholland told me. The goal isn’t to achieve perfection right out of the lab, but rather to optimize the experiments companies end up having to do. “We still need to prove materials in the real world, because the real world will complicate it.”
Indeed it will. For one thing, while AI is capable of churning out millions of hypothetical materials — as a tool developed by Google DeepMind did in 2023 — materials scientists have since shown that many are just variants of known compounds, while others are unstable, unable to be synthesized, or otherwise irrelevant under real world conditions.
Such failures likely stem, in part, from another common limitation of AI models trained solely on publicly available materials and chemicals data: Academic research tends to report only successful outcomes, omitting data on what didn’t work and which compounds weren’t viable. That can lead models to be overly optimistic about the magnitude and potential of possible materials solutions and generate unrealistic “discoveries” that may have already been tested and rejected.
Because Citrine’s platform is deployed within customer organizations, it can largely sidestep this problem by tuning its model on niche, proprietary datasets. These datasets are small when compared with the vast public repositories used to train Citrine’s base model, but the granular information they contain about prior experiments — both successes and failures — has proven critical to bringing new discoveries to market.
While the holy grail for materials science may be a model trained on all the world’s relevant data — public and private, positive and negative — at this point that’s just a fantasy, one of Citrine’s investors, Mark Cupta of Prelude Ventures, told me over email. “It’s hard to get buy-in from the entire material development world to make an open-source model that pulls in data from across the field.”
Citrine’s last raise, which Prelude co-led, came at the very beginning of 2023, as the AI wave was still gathering momentum. But Mulholland said there’s no rush to raise additional capital — in fact, he expects Citrine to turn a profit in the next year or so.
That milestone would strongly validate the company’s strategy, which banks on steady revenue from its subscription-based model to compensate for the fact that it doesn’t own the intellectual property for the materials it helps develop. While Mulholland told me that many players in this space are trying to “invent new materials and patent them and try to sell them like drugs,” Citriene is able to “invent things much more quickly, in a more realistic way than the pie in the sky, hoping for a Nobel Prize [approach].”
Citrines is also careful to assure that its model accounts for real world constraints such as regulations and production bottlenecks. Say a materials company is creating an aluminum alloy for an automaker, Mulholland explained — it might be critical to stay within certain elemental bounds. If the company were to add in novel elements, the automaker would likely want to put its new compound through a rigorous testing process, which would be annoying if it’s looking to get to market as quickly as possible. Better, perhaps, to tinker around the edges of what’s well understood.
In fact, Mulholland told me it’s often these marginal improvements that initially bring customers into the fold, convincing them that this whole AI-for-materials thing is more than just hype. “The first project is almost always like, make the adhesive a little bit stickier — because that’s a good way to prove to these skeptical scientists that AI is real and here to stay,” he said. “And then they use that as justification to invest further and further back in their product development pipeline, such that their whole product portfolio can be optimized by AI.”
Overall, the company says that its new framework can speed up materials development by 80%. So while Mulholland and Citrine overall may not be going for the Nobel in Chemistry, don’t doubt for a second that they’re trying to lead a fundamental shift in the way consumer products are designed.
“I’m as bullish as I can possibly be on AI in science,” Mulholland told me. “It is the most exciting time to be a scientist since Newton. But I think that the gap between scientific discovery and realized business is much larger than a lot of AI folks think.”
Plus more insights from Heatmap’s latest event Washington, D.C.
At Heatmap’s event, “Supercharging the Grid,” two members of the House of Representatives — a California Democrat and a Colorado Republican — talked about their shared political fight to loosen implementation of the National Environmental Policy Act to accelerate energy deployment.
Representatives Gabe Evans and Scott Peters spoke with Heatmap’s Robinson Meyer at the Washington, D.C., gathering about how permitting reform is faring in Congress.
“The game in the 1970s was to stop things, but if you’re a climate activist now, the game is to build things,” said Peters, who worked as an environmental lawyer for many years. “My proposal is, get out of the way of everything and we win. Renewables win. And NEPA is a big delay.”
NEPA requires that the federal government review the environmental implications of its actions before finalizing them, permitting decisions included. The 50-year-old environmental law has already undergone several rounds of reform, including efforts under both Presidents Biden and Trump to remove redundancies and reduce the size and scope of environmental analyses conducted under the law. But bottlenecks remain — completing the highest level of review under the law still takes four-and-a-half years, on average. Just before Thanksgiving, the House Committee on Natural Resources advanced the SPEED Act, which aims to ease that congestion by creating shortcuts for environmental reviews, limiting judicial review of the final assessments, and preventing current and future presidents from arbitrarily rescinding permits, subject to certain exceptions.
Evans framed the problem in terms of keeping up with countries like China on building energy infrastructure. “I’ve seen how other parts of the world produce energy, produce other things,” said Evans. “We build things cleaner and more responsibly here than really anywhere else on the planet.”
Both representatives agreed that the SPEED Act on its own wouldn’t solve all the United States’ energy issues. Peters hinted at other permitting legislation in the works.
“We want to take that SPEED Act on the NEPA reform and marry it with specific energy reforms, including transmission,” said Peters.
Next, Neil Chatterjee, a former Commissioner of the Federal Energy Regulatory Commission, explained to Rob another regulatory change that could affect the pace of energy infrastructure buildout: a directive from the Department of Energy to FERC to come up with better ways of connecting large new sources of electricity demand — i.e. data centers — to the grid.
“This issue is all about data centers and AI, but it goes beyond data centers and AI,” said Chatterjee. “It deals with all of the pressures that we are seeing in terms of demand from the grid from cloud computing and quantum computing, streaming services, crypto and Bitcoin mining, reshoring of manufacturing, vehicle electrification, building electrification, semiconductor manufacturing.”
Chatterjee argued that navigating load growth to support AI data centers should be a bipartisan issue. He expressed hope that AI could help bridge the partisan divide.
“We have become mired in this politics of, if you’re for fossil fuels, you are of the political right. If you’re for clean energy and climate solutions, you’re the political left,” he said. “I think AI is going to be the thing that busts us out of it.”
Updating and upgrading the grid to accommodate data centers has grown more urgent in the face of drastically rising electricity demand projections.
Marsden Hanna, Google’s head of energy and dust policy, told Heatmap’s Jillian Goodman that the company is eyeing transmission technology to connect its own data centers to the grid faster.
“We looked at advanced transition technologies, high performance conductors,” said Hanna. “We see that really as just an incredibly rapid, no-brainer opportunity.”
Advanced transmission technologies, otherwise known as ATTs, could help expand the existing grid’s capacity, freeing up space for some of the load growth that economy-wide electrification and data centers would require. Building new transmission lines, however, requires permits — the central issue that panelists kept returning to throughout the event.
Devin Hartman, director of energy and environmental policy at the R Street Institute, told Jillian that investors are nervous that already-approved permits could be revoked — something the solar industry has struggled with under the Trump administration.
“Half the battle now is not just getting the permits on time and getting projects to break ground,” said Hartman. “It’s also permitting permanence.”
This event was made possible by the American Council on Renewable Energy’s Macro Grid Initiative.
On gas turbine backorders, Europe’s not-so-green deal, and Iranian cloud seeding
Current conditions: Up to 10 inches of rain in the Cascades threatens mudslides, particularly in areas where wildfires denuded the landscape of the trees whose roots once held soil in place • South Africa has issued extreme fire warnings for Northern Cape, Western Cape, and Eastern Cape • Still roiling from last week’s failed attempt at a military coup, Benin’s capital of Cotonou is in the midst of a streak of days with temperatures over 90 degrees Fahrenheit and no end in sight.

Exxon Mobil Corp. plans to cut planned spending on low-carbon projects by a third, joining much of the rest of its industry in refocusing on fossil fuels. The nation’s largest oil producer said it would increase its earnings and cash flow by $5 billion by 2030. The company projected earnings to grow by 13% each year without any increase in capital spending. But the upstream division, which includes exploration and production, is expected to bring in $14 billion in earnings growth compared to 2024. The key projects The Wall Street Journal listed in the Permian Basin, Guyana and at liquified natural gas sites would total $4 billion in earnings growth alone over the next five years. The announcement came a day before the Department of the Interior auctioned off $279 million of leases across 80 million acres of federal waters in the Gulf of Mexico.
Speaking of oil and water, early Wednesday U.S. armed forces seized an oil tanker off the coast of Venezuela in what The New York Times called “a dramatic escalation in President Trump’s pressure campaign against Nicolás Maduro.” When asked what would become of the vessel's oil, Trump said at the White House, “Well, we keep it, I guess.”
The Federal Reserve slashed its key benchmark interest rate for the third time this year. The 0.25 percentage point cut was meant to calibrate the borrowing costs to stay within a range between 3.5% and 3.75%. The 9-3 vote by the central bank’s board of governors amounted to what Wall Street calls a hawkish cut, a move to prop up a cooling labor market while signaling strong concerns about future downward adjustments that’s considered so rare CNBC previously questioned whether it could be real. But it’s good news for clean energy. As Heatmap’s Matthew Zeitlin wrote after the September rate cut, lower borrowing costs “may provide some relief to renewables developers and investors, who are especially sensitive to financing costs.” But it likely isn’t enough to wipe out the effects of Trump’s tariffs and tax credit phaseouts.
GE Vernova plans to increase its capacity to manufacture gas turbines by 20 gigawatts once assembly line expansions are completed in the middle of next year. But in a presentation to investors this week, the company said it’s already sold out of new gas turbines all the way through 2028, and has less than 10 gigawatts of equipment left to sell for 2029. It’s no wonder supersonic jet startups, as I wrote about in yesterday’s newsletter, are now eyeing a near-term windfall by getting into the gas turbine business.

The European Union will free more than 80% of the companies from environmental reporting rules under a deal struck this week. The agreement between EU institutions marks what Politico Europe called a “major legislative victory” for European Commission President Ursula von der Leyen, who has sought to make the bloc more economically self-sufficient by cutting red tape for business in her second term in office. The rollback is also a win for Trump, whose administration heavily criticized the EU’s green rules. It’s also a victory for the U.S. president’s far-right allies in Europe. The deal fractured the coalition that got the German politician reelected to the EU’s top job, forcing her center-right faction to team up with the far right to win enough votes for secure victory.
Ravaged by drought, Iran is carrying out cloud-seeding operations in a bid to increase rainfall amid what the Financial Times clocked as “the worst water crisis in six decades.” On Tuesday, Abbas Aliabadi, the energy minister, said the country had begun a fresh round of injecting crystals into clouds using planes, drones, and ground-based launchers. The country has even started developing drones specifically tailored to cloud seeding.
The effort comes just weeks after the Islamic Republic announced that it “no longer has a choice” but to move its capital city as ongoing strain on water supplies and land causes Tehran to sink by nearly one foot per year. As I wrote in this newsletter, Iranian President Masoud Pezeshkian called the situation a “catastrophe” and “a dark future.”
The end of suburban kids whiffing diesel exhaust in the back of stuffy, rumbling old yellow school buses is nigh. The battery-powered bus startup Highland Electric Fleets just raised $150 million in an equity round from Aiga Capital Partners to deploy its fleets of buses and trucks across the U.S., Axios reported. In a press release, the company said its vehicles would hit the streets by next year.
