Don’t let the political process intimidate you.

Driving less has a lot of benefits. You’ll be healthier than your vehicle-bound peers, about a third of whom don’t walk for more than 10 minutes a week. You’ll cut carbon dioxide, nitrous oxide, and methane emissions. In the process, you’ll probably realize how awful America’s public and active transportation infrastructure is — and may want to do something about it.
The same goes for just about any action you’ll find in Heatmap’s guide to decarbonizing your life. Should it be easier to get a permit to install rooftop solar panels? For sure. Should there be more public chargers to support EV adoption in your community? Without a doubt.
It can be especially overwhelming to think about getting involved in your local political processes when it comes to mobility because the cards are stacked so heavily in drivers’ favor. But it’s far from impossible. Here’s Heatmap’s guide to advocating for better transportation options and infrastructure in your community.
This might be the hardest step of all. To take transportation as an example, most American cities and towns were literally constructed to get drivers from point A to point B as fast as possible — meaning that their design is often actively hostile to anyone who wants to walk, bike, or take mass transit instead. If you put your mind to it, you could probably devise a dozen ways to make your immediate neighborhood friendlier to carless commuters.
Transportation for America’s transit advocate guide has several suggested starting places, including advocating for additional late-night service on a particular bus route, improving access to transit stations or stops (known as first- or last-mile connectivity), and pushing for shuttle services to connect riders with jobs. Petitioning for something like a bike lane, new sidewalk, safer intersections, or a missing crosswalk is another good place to start.
“Focus on one individual project,” Alexa Sledge, the communications director at Transportation Alternatives, a New York City nonprofit promoting non-polluting, safe, and quiet travel, told me. Being clear and focused on what you want — and, importantly, not getting overwhelmed or pulled in multiple directions — will help you achieve your goal. Strong Towns, a nonprofit that supports transportation advocates, calls this step the “humble observation:” identifying where people are struggling in your community and zeroing in on the smallest first possible step to help.
Here’s the excellent news: You aren’t in this fight alone.
Pretty much every major city and metropolitan region in the U.S. has its own transportation advocacy group these days, and you’re potentially just a Google search away from locating yours. (If you can’t find a transportation-specific group, look into local climate or pedestrian organizations, which frequently have overlapping objectives.)
It’s important to link up with others not just because they might already have identified priority projects in your area. Advocating for structural change requires, by definition, allies — and unfortunately, car-centricity is so dominant that transit advocates are often forced to prove the obvious community benefits of things like better bus routes or protected bike lanes.
If you don’t live in an area with an active transit group, nationwide organizations like Transportation for America and Strong Towns can connect with to get the tools, resources, training, and advice you need to start gathering allies.
How do I change a zoning law? Or weigh in on a renewable energy project near me?
Maybe you’re reading this guide because you’re interested in advocating climate-conscious zoning reform or want to weigh in on a wind farm nearby. There is a “profound diversity” of processes to do so from municipality to municipality, and no one-size-fits-all approach. That’s why it’s extra important to get involved with a local advocacy group; veteran organizers in your area can help you navigate the labyrinthine processes of your specific local government.
That said, here are a few things to keep your eyes peeled for:
There is an old urban planning joke about how traffic woes could be fixed by adding just one more lane. (They can’t be). Alas, this is also something of a federal policy; even though the 2021 Bipartisan Infrastructure Law set aside $36 billion to “transform our transportation system,” many states used their flexible funds for things like widening roads. Mass and active transit are often only an afterthought when it comes to funding: the Capital Investment Grants Program, one of the most significant federal programs for transit, is on the chopping block every budget-writing session, and programs like the Highway Trust Fund puts as little as 13% toward mass transit.
It’s our elected officials who make these decisions, though — and it’s their job to listen to their constituents. Here’s a handy page for determining the relevant senators and representatives to contact about federal funding for transit and active mobility policies; for local projects, you’ll want to reach out to your city council members, whose names and email addresses or phone numbers you should be able to find on your city website. And if you feel you’re getting brushed off by city staff when you reach out, focus on the smallest possible steps forward and be persistent (you can learn more strategies here).
The truth is, most people don’t go to their city council meetings. “When you really get down to the local level, there often aren’t as many people fighting, so you really can make a big difference,” Sledge said. Speaking up at hearings, town halls, public comment periods, or city council meetings can result in significant change and progress.
But let’s face it: Because most of us don’t have experience in local activism, telling someone to “go to a city council meeting” is much easier said than done. “The thing to remember is that your city council members work for you,” Sledge said. “They are elected members of your government, and you vote for them, and they are paid with taxpayer money. It’s part of their job to listen to you.”
Doug Gordon, the cohost of The War on Cars, a podcast about the fight against car culture, also suggested taking some of the pressure off yourself. “Don’t feel like you have to give the rousing patriotic speech in defense of the neighborhood bike lane,” he told me. “Just go and listen, and maybe if all that’s asked of you is to raise your hand when they ask how many people support this project, and that’s all you do, great.”
You don’t necessarily need to show up at a town council meeting or a representative’s office, either. Sledge suggested taking smaller steps like a phone call or email, or even just talking to people in your immediate community (for example, if you want a crosswalk outside your kid’s school, start by talking to the school board or other parents). When approaching someone like your city counselor, use language like: “This crosswalk is really important to me. How do I get this done?”
1. Depending on the project you’re pursuing, look up when your local transportation authority is inviting public comments ( here’s an example of what that page looks like in New York City). You can also search for when your state is holding public transportation hearings (here’s what Oklahoma’s looks like) and contact the relevant representatives to express your views. Most likely, though, you’ll be looking for your town’s public meeting schedule (here’s an example of San Jose’s) and seeking a special session related to transportation or a regular business meeting. Virtual hearings have also been common since the pandemic.
2. Research beforehand to learn how to comment publicly in your city or town. This may involve signing up on the town’s website or on a sign-in sheet when you arrive at the hearing.
3. In most cases, during the public comment portion of the city council meeting, you can address the council on any public issue (it does not have to be on the agenda). Again, check your city or town’s website to learn the specifics of procedures. Also, be aware of the time limit for your comments; generally, you’ll have about three minutes.
When you’re called on:
During your comment, you will probably see a timer somewhere in the room to help you track how long you have left to speak. The best comments are short and concise. Even if you’re frustrated with the process, be polite; remember that your comment can be seen and cited by anyone, including the media. Speak slowly. Here’s a guide for making an effective public comment from the National Resources Defense Council, with a sample script.
“If changing the system was easy,” writes Strong Towns, “we’d have done it long ago.” Many campaigns take years to come to fruition — being persistent and building a consensus, so advocates are working together toward the same cause, are two of the biggest lessons for success that Transportation for America stresses in their case studies.
It may take getting creative. Join the greater transportation advocacy community; listen to relevant podcasts, read related books, watch relevant YouTube videos, and learn from other campaigns. “You need a website, you need a public petition, and you need a T-shirt, because otherwise you’re just somebody with an opinion,” Rob Goodspeed, a founder of Trains Not Lanes, which successfully convinced Michigan’s Department of Transportation to drop highway expansion plans, told Streetsblog.
And when you do finally succeed? Celebrate. Promote it. Share your lessons with other organizers. Then identify a new project and begin again.

A federal judge in Massachusetts ruled that construction on Vineyard Wind could proceed.
The Vineyard Wind offshore wind project can continue construction while the company’s lawsuit challenging the Trump administration’s stop work order proceeds, judge Brian E. Murphy for the District of Massachusetts ruled on Tuesday.
That makes four offshore wind farms that have now won preliminary injunctions against Trump’s freeze on the industry. Dominion Energy’s Coastal Virginia offshore wind project, Orsted’s Revolution Wind off the coast of New England, and Equinor’s Empire Wind near Long Island, New York, have all been allowed to proceed with construction while their individual legal challenges to the stop work order play out.
The Department of the Interior attempted to pause all offshore wind construction in December, citing unspecified “national security risks identified by the Department of War.” The risks are apparently detailed in a classified report, and have been shared neither with the public nor with the offshore wind companies.
Vineyard Wind, a joint development between Avangrid Renewables and Copenhagen Infrastructure Partners, has been under construction since 2021, and is already 95% built. More than that, it’s sending power to Massachusetts customers, and will produce enough electricity to power up to 400,000 homes once it’s complete.
In court filings, the developer argued it was urgent the stop work order be lifted, as it would lose access to a key construction boat required to complete the project on March 31. The company is in the process of replacing defective blades on its last handful of turbines — a defect that was discovered after one of the blades broke in 2024, scattering shards of fiberglass into the ocean. Leaving those turbine towers standing without being able to install new blades created a safety hazard, the company said.
“If construction is not completed by that date, the partially completed wind turbines will be left in an unsafe condition and Vineyard Wind will incur a series of financial consequences that it likely could not survive,” the company wrote. The Trump administration submitted a reply denying there was any risk.
The only remaining wind farm still affected by the December pause on construction is Sunrise Wind, a 924-megawatt project being developed by Orsted and set to deliver power to New York State. A hearing for an injunction on that order is scheduled for February 2.
Noon Energy just completed a successful demonstration of its reversible solid-oxide fuel cell.
Whatever you think of as the most important topic in energy right now — whether it’s electricity affordability, grid resilience, or deep decarbonization — long-duration energy storage will be essential to achieving it. While standard lithium-ion batteries are great for smoothing out the ups and downs of wind and solar generation over shorter periods, we’ll need systems that can store energy for days or even weeks to bridge prolonged shifts and fluctuations in weather patterns.
That’s why Form Energy made such a big splash. In 2021, the startup announced its plans to commercialize a 100-plus-hour iron-air battery that charges and discharges by converting iron into rust and back again. The company’s CEO, Mateo Jaramillo, told The Wall Street Journal at the time that this was the “kind of battery you need to fully retire thermal assets like coal and natural gas power plants.” Form went on to raise a $240 million Series D that same year, and is now deploying its very first commercial batteries in Minnesota.
But it’s not the only player in the rarified space of ultra-long-duration energy storage. While so far competitor Noon Energy has gotten less attention and less funding, it was also raising money four years ago — a more humble $3 million seed round, followed by a $28 million Series A in early 2023. Like Form, it’s targeting a price of $20 per kilowatt-hour for its electricity, often considered the threshold at which this type of storage becomes economically viable and materially valuable for the grid.
Last week, Noon announced that it had completed a successful demonstration of its 100-plus-hour carbon-oxygen battery, partially funded with a grant from the California Energy Commission, which charges by breaking down CO2 and discharges by recombining it using a technology known as a reversible solid-oxide fuel cell. The system has three main components: a power block that contains the fuel cell stack, a charge tank, and a discharge tank. During charging, clean electricity flows through the power block, converting carbon dioxide from the discharge tank into solid carbon that gets stored in the charge tank. During discharge, the system recombines stored carbon with oxygen from the air to generate electricity and reform carbon dioxide.
Importantly, Noon’s system is designed to scale up cost-effectively. That’s baked into its architecture, which separates the energy storage tanks from the power generating unit. That makes it simple to increase the total amount of electricity stored independent of the power output, i.e. the rate at which that energy is delivered.
Most other batteries, including lithium-ion and Form’s iron-air system, store energy inside the battery cells themselves. Those same cells also deliver power; thus, increasing the energy capacity of the system requires adding more battery cells, which increases power whether it’s needed or not. Because lithium-ion cells are costly, this makes scaling these systems for multi-day energy storage completely uneconomical.
In concept, Noon’s ability to independently scale energy capacity is “similar to pumped hydro storage or a flow battery,” Chris Graves, the startup’s CEO, told me. “But in our case, many times higher energy density than those — 50 times higher than a flow battery, even more so than pumped hydro.” It’s also significantly more energy dense than Form’s battery, he said, likely making it cheaper to ship and install (although the dirt cheap cost of Form’s materials could offset this advantage.)
Noon’s system would be the first grid-scale deployment of reversible solid-oxide fuel cells specifically for long-duration energy storage. While the technology is well understood, historically reversible fuel cells have struggled to operate consistently and reliably, suffering from low round trip efficiency — meaning that much of the energy used to charge the battery is lost before it’s used — and high overall costs. Graves conceded Noon has implemented a “really unique twist” on this tech that’s allowed it to overcome these barriers and move toward commercialization, but that was as much as he would reveal.
Last week’s demonstration, however, is a big step toward validating this approach. “They’re one of the first ones to get to this stage,” Alexander Hogeveen Rutter, a manager at the climate tech accelerator Third Derivative, told me. “There’s certainly many other companies that are working on a variance of this,” he said, referring to reversible fuel cell systems overall. But none have done this much to show that the technology can be viable for long-duration storage.
One of Noon’s initial target markets is — surprise, surprise — data centers, where Graves said its system will complement lithium-ion batteries. “Lithium ion is very good for peak hours and fast response times, and our system is complementary in that it handles the bulk of the energy capacity,” Graves explained, saying that Noon could provide up to 98% of a system’s total energy storage needs, with lithium-ion delivering shorter streams of high power.
Graves expects that initial commercial deployments — projected to come online as soon as next year — will be behind-the-meter, meaning data centers or other large loads will draw power directly from Noon’s batteries rather than the grid. That stands in contrast to Form’s approach, which is building projects in tandem with utilities such as Great River Energy in Minnesota and PG&E in California.
Hogeveen Rutter, of Third Derivative, called Noon’s strategy “super logical” given the lengthy grid interconnection queue as well as the recent order from the Federal Energy Regulatory Commission intended to make it easier for data centers to co-locate with power plants. Essentially, he told me, FERC demanded a loosening of the reins. “If you’re a data center or any large load, you can go build whatever you want, and if you just don’t connect to the grid, that’s fine,” Hogeveen Rutter said. “Just don’t bother us, and we won’t bother you.”
Building behind-the-meter also solves a key challenge for ultra-long-duration storage — the fact that in most regions, renewables comprise too small a share of the grid to make long-duration energy storage critical for the system’s resilience. Because fossil fuels still meet the majority of the U.S.’s electricity needs, grids can typically handle a few days without sun or wind. In a world where renewables play a larger role, long-duration storage would be critical to bridging those gaps — we’re just not there yet. But when a battery is paired with an off-grid wind or solar plant, that effectively creates a microgrid with 100% renewables penetration, providing a raison d’être for the long-duration storage system.
“Utility costs are going up often because of transmission and distribution costs — mainly distribution — and there’s a crossover point where it becomes cheaper to just tell the utility to go pound sand and build your power plant,” Richard Swanson, the founder of SunPower and an independent board observer at Noon, told me. Data centers in some geographies might have already reached that juncture. “So I think you’re simply going to see it slowly become cost effective to self generate bigger and bigger sizes in more and more applications and in more and more locations over time.”
As renewables penetration on the grid rises and long-duration storage becomes an increasing necessity, Swanson expects we’ll see more batteries like Noon’s getting grid connected, where they’ll help to increase the grid’s capacity factor without the need to build more poles and wires. “We’re really talking about something that’s going to happen over the next century,” he told me.
Noon’s initial demo has been operational for months, cycling for thousands of hours and achieving discharge durations of over 200 hours. The company is now fundraising for its Series B round, while a larger demo, already built and backed by another California Energy Commission grant, is set to come online soon.
While Graves would not reveal the size of the pilot that’s wrapping up now, this subsequent demo is set to deliver up to 100 kilowatts of power at once while storing 10 megawatt-hours of energy, enough to operate at full power for 100 hours. Noon’s full-scale commercial system is designed to deliver the same 100-hour discharge duration while increasing the power output to 300 kilowatts and the energy storage capacity to 30 megawatt-hours.
This standard commercial-scale unit will be shipping container-sized, making it simple to add capacity by deploying additional modules. Noon says it already has a large customer pipeline, though these agreements have yet to be announced. Those deals should come to light soon though, as Swanson says this technology represents the “missing link” for achieving full decarbonization of the electricity sector.
Or as Hogeveen Rutter put it, “When people talk about, I’m gonna get rid of all my fossil fuels by 2030 or 2035 — like the United Kingdom and California — well this is what you need to do that.”
On aluminum smelting, Korean nuclear, and a geoengineering database
Current conditions: Winter Storm Fern may have caused up to $115 billion in economic losses and triggered the longest stretch of subzero temperatures in New York City’s history • Temperatures across the American South plunged up to 30 degrees Fahrenheit below historical averages • South Africa’s Northern Cape is roasting in temperatures as high as 104 degrees.

President Donald Trump has been on quite a shopping spree since taking an equity stake in MP Materials, the only active rare earths miner in the U.S., in a deal Heatmap’s Matthew Zeitlin noted made former Biden administration officials “jealous.” The latest stake the administration has taken for the American taxpayer is in USA Rare Earth, a would-be miner that has focused its attention establishing a domestic manufacturing base for the rare earth-based magnets China dominates. On Monday, the Department of Commerce announced a deal to inject $1.6 billion into the company in exchange for shares. “USA Rare Earth’s heavy critical minerals project is essential to restoring U.S. critical mineral independence,” Secretary of Commerce Howard Lutnick said in a statement. “This investment ensures our supply chains are resilient and no longer reliant on foreign nations.” In a call with analysts Monday, USA Rare Earth CEO Barbara Humpton called the deal “a watershed moment in our work to secure and grow a resilient and independent rare earth value chain based in this country.”
After two years of searching for a site to build the United States’ first new aluminum smelter in half a century, Century Aluminum has abandoned its original plan and opted instead to go into business with a Dubai-based rival developing a plant in Oklahoma. Emirates Global Aluminum announced plans last year to construct a smelter near Tulsa. Under the new plan, Century Aluminum would take a 40% stake in the venture, with Emirates Global Aluminum holding the other 60%. At peak capacity, the smelter would produce 750,000 tons of aluminum per year, a volume The Wall Street Journal noted would make it the largest smelter in the U.S. Emirates Global Aluminum has not yet announced a long-term contract to power the facility. Century Aluminum’s original plan was to use 100% of its power from renewables or nuclear, Canary Media reported, and received $500 million from the Biden administration to support the project.
The federal Mine Safety and Health Administration has stopped publishing data tied to inspections of sites with repeated violations, E&E News reported. At a hearing before the House Education & the Workforce Subcommittee on Workforce Protections last week, Wayne Palmer, the assistant secretary of labor for mine safety and health, said the data would no longer be made public. “To the best of my knowledge, we do not publish those under the current administration,” Palmer said. He said the decision to not make public results of “targeted inspections” predated his time at the agency. The move comes as the Trump administration is pushing to ramp up mining in the U.S. to compete with China’s near monopoly over key metals such as rare earths, and lithium. As Heatmap’s Katie Brigham wrote in September, “everybody wants to invest in critical minerals.”

South Korea’s center-left Democratic Party has historically been staunchly anti-nuclear. So when the country’s nuclear regulator licensed a new plant earlier this month — its first under a new Democratic president — I counted it as a win for the industry. Now President Lee Jae-myung’s administration is going all in all on atomic energy. On Monday, NucNet reported that the state-owned Korea Hydro & Nuclear Power plans to open bidding for sites for two new large reactors. The site selection is set to take up to six months. The country then plans to begin construction in the early 2030s and bring the reactors online in 2037 and 2038. Kim Sung-whan, the country’s climate minister, said the Lee administration would stick to the nuclear buildout plan authored in February 2025 under former President Yoon Suk Yeol, a right-wing leader who strongly supported the atomic power industry before being ousted from power after attempting to declare martial law.
Reflective, a nonprofit group that bills itself as “aiming to radically accelerate the pace of sunlight reflection research,” launched its Uncertainty Database on Monday, with the aim of providing scientists, funders, and policymakers with “an initial foundation to create a transparent, prioritized, stage-gated” roadmap of different technologies to spray aerosols in the atmosphere to artificially cool the planet. “SAI research is currently fragmented and underpowered, with no shared view of which uncertainties actually matter for real-world decisions,” Dakota Gruener, the chief executive of Reflective, said in a statement. “We need a shared, strategic view of what we know, what we don’t, and where research can make the biggest difference. The Uncertainty Database helps the field prioritize the uncertainties and research that matter most for informed decisions about SAI.” The database comes as the push to research geoengineering technologies goes mainstream. As Heatmap’s Robinson Meyer reported in October, Stardust Solutions, a U.S. firm run by former Israeli government physicists, has already raised $60 million in private capital to commercialize technology that many climate activists and scientists still see as taboo to even study.
Often we hear of the carbon-absorbing potential of towering forest trees or fast-growing algae. But nary a word on the humble shrub. New research out of China suggests the bush deserves another look. An experiment in planting shrubs along the edges of western China’s Taklamakan Desert over the past four decades has not only kept desertification at bay, it’s made a dent in carbon emissions from the area. “This is not a rainforest,” King-Fai Li, a physicist at the University of California at Riverside, said in a statement. “It’s a shrubland like Southern California’s chaparral. But the fact that it’s drawing down CO2 at all, and doing it consistently, is something positive we can measure and verify from space.” The study provides a rare, long-term case study of desert greening, since this effort has endured for decades whereas one launched in the Sahara Desert by the United Nations crumbled.
