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.

The spinoff of Lawrence Livermore National Lab has a new 10-point plan to get onto the grid by the 2030s.
One of fusion energy’s newest startups, Inertia Enterprises, is betting that the fastest route to commercial fusion runs through one of the field’s oldest ideas. The company, which raised a $450 million Series A earlier this year, plans to build a power plant based on the laser-driven fusion system pioneered at Lawrence Livermore National Laboratory’s — the only tech yet to have produced more energy from a fusion reaction than it took to initiate it. Now, Inertia has shared its commercialization roadmap exclusively with Heatmap, detailing the 10 near-term capabilities it must demonstrate before this landmark experiment can become a grid-scale power plant by the mid-2030s.
The roadmap offers a route from the national lab’s impressive but commercially impractical fusion demonstrations to an economical power plant capable of producing electricity for the grid. At its core are a set of milestones — mostly aimed at developing cheap, mass-manufacturable components — that Inertia says it must clear before those individual systems can be integrated into a working plant. This road is not necessarily linear, however, as various teams will likely be working on many of these goals simultaneously.
At least the physics of Inertia’s approach are already proven, the startup’s CEO Jeff Lawson told me, pointing to the fusion experiments at Lawrence Livermore’s National Ignition Facility as a proof-of-concept. The lab’s demonstration of net energy gain caps more than six decades and $30 billion (in 2026 dollars) of U.S. fusion research. The remaining challenges, he argued, are all engineering-related, requiring “elbow grease, hard work, and smart people” rather than breakthroughs in fusion science.
"It seems to us like a startup or a commercial company of any variety should be focused on commercializing a proven scientific result, as opposed to actually trying to demonstrate the basic science to begin with," Lawson told me. Basic science, he argues, is better left to national labs and universities, where researchers can pursue "unbounded problems" that don’t align with the expectations and timelines of venture-backed startups.
Indeed, no fusion startup has yet achieved scientific breakeven, the milestone Lawrence Livermore first hit in 2022, and has since repeated numerous times. But leading players such as Commonwealth Fusion Systems and Helion Energy maintain that it’s only a matter of time before they validate the physics behind their own reactor designs, which they claim will be highly cost-competitive.
Lawson, on the other hand, readily acknowledged that Lawrence Livermore’s tech is uneconomical in its current form. His bet is simply that the more predictable path to a commercial reactor is to drive down the cost of the lab’s validated fusion approach, known as inertial confinement. This system relies on high-powered lasers firing at a millimeter-scale pellet of fusion fuel, compressing it to extreme temperatures and pressures until the atoms fuse. Today, the National Ignition Facility makes each individual fusion target by hand, a workable solution given that it only uses about a dozen per year.
That production model, however, isn’t remotely plausible for a grid-scale power plant. Because each fusion reaction lasts just a fraction of a billionth of a second, a commercial facility must fire its lasers at a fresh target about 10 times per second to generate continuous electricity — requiring the production of hundreds of millions of targets each year.
Scaling production to roughly a million pellets per day and making them inexpensive enough for commercial operation without compromising the strength or precision required for fusion ignition is central to Inertia’s roadmap. That includes goals five, seven, eight and nine — industrializing the manufacturing of the carbon shells that hold the fusion fuel, making the thin films that hold those carbon shells both durable and cheap, scaling up and automating fusion target assembly, and speeding up how fast targets are filled with the requisite deuterium-tritium fuel.
The other central focus of the roadmap is the laser system, which will ultimately consist of 1,000 individual units operating in concert to compress and heat the fusion fuel. Key priorities include reducing the system’s cost (goal two), dramatically increasing its firing cadence (goal three), and bolstering its durability to withstand high-intensity operations (goal four). Goal six also complements these efforts, calling for the development of a control system capable of tracking moving fusion targets to precisely align each laser shot.
Goals one and 10 bookend the journey with some broader milestones. The first focuses on increasing the fusion target’s energy gain — the ratio of fusion energy produced to laser energy delivered — to more than 25 times ignition. Today, the National Ignition Facility’s best-performing laser shot has yielded a gain of just over four times what it took to start the reaction. Goal 10 then zooms out to the ultimate objective: integrating all these technologies into a commercially viable power plant that can deliver either electricity or industrial heat to end customers.
To reach that point, Inertia has embarked on an industrial engineering hiring spree, recruiting folks with experience taking complex hardware systems from prototype to mass production, “not unlike the processes that are used in the semiconductor or consumer electronics world,” Lawson explained. The company has been making progress on its component development goals since the beginning of the year, he told me, and expects to announce the successful demonstration of a few of these milestones in the coming months. Lawson ultimately expects Inertia to complete the core components of its laser and target manufacturing systems by the middle of next year.
The team will spend the next two to three years integrating these individual pieces into two fully operational subsystems, a prototype laser system and a target manufacturing line. Around 2030, the company will begin combining those subsystems into a first-of-a-kind fusion power plant, which will also serve as the proving ground for the target chamber, tritium fuel breeding system, and power conversion system that turns fusion heat into electricity. By the middle of the next decade, Inertia aims to be generating power from this first plant, setting the stage for the company to build and connect additional grid-scale commercial power plants.
There are plenty of engineering trade-offs that the company will have to solve for. Take the decision around how to size the target chamber, for example. “If you make it bigger, your walls have an easier time and survive longer, but it’s more expensive. If you make it smaller, your walls have a tougher time because they’re closer to all the heat and energy that the fusion reaction is creating, but now your power plant costs less to build.”
But to Lawson, this represents exactly the type of problem Inertia was built to solve: complex engineering issues that come to the fore once scientists have demonstrated the fundamental physics are sound. He thinks other fusion companies may someday reach this stage, as well — though he’s unwilling to hazard a guess on exactly what approach or startup is best positioned to do so.
“There have been generations of scientists who’ve made their predictions about fusion energy and gotten it wrong,” he told me. “I’m not going to pretend to be smarter than them. All I’m here to say is, just knowing that one did work, we can commercialize it.”
