On August 9, 2023, the smoke finally cleared in Lahaina.
The scene was shocking. In the course of just a few hours on the afternoon of August 8, winds had fanned a dry grass fire on the northwest coast of Maui into an inferno that trapped fleeing residents and left more than 100 people dead and the city in ashes. “We understand that recovery will take years,” Kaniela Ing, the national director of the Green New Deal Network and a seventh-generation Indigenous Hawaiian, told me when we spoke in the immediate aftermath of the tragedy. “And as that recovery unfolds, we want to make sure that the people, the communities, are actually empowered to rebuild themselves — that we don’t open the door for disaster capitalists.”
Since then, Ing and other community leaders have put in the work. Over the past year, their group, Lahaina Strong, has tried to empower the community and challenge the power structures they say contributed to the confluence of factors that made the fire possible.
“We’re all about the community arm — grassroots power, and coalitions,” he told me this week. “Unfortunately, our groups are the same groups that have had to respond to climate disasters like Hurricanes Maria, Harvey, Sandy, and the Paradise fires. There’s always something, and it’s getting more and more frequent.”
On the anniversary of the fire, I spoke to Ing about how other communities can learn from the Lahaina model, the victories organizers secured to ensure a better future for native Hawaiians and locals, and how to ride the momentum forward into November. Our conversation has been condensed and edited for clarity and brevity.
It’s been almost a year since we last spoke; at that time, you’d just arrived in Maui from your home on Oahu after the fire. What happened after that?
I don’t think there had been a clear model of best practices for how to respond. So when [a climate disaster] happened in my backyard, it was like, “Okay, let’s learn from all the responses and organizing traditions that we’ve studied and been trained on” — from the Civil Rights era to the mutual aid of the Black Panthers and tenant rights and welfare organizers, to the modern efforts of the Alinsky-type ACORN model, to the Sunrise model, which is momentum-based. But how do you draw from everything at once?
That is where Lahaina Strong came from. Because this is where I grew up, we knew which community leaders would be stepping up. But it’s not common for everyone to work together — they can be on different sides of different issues. So we convened all of them — mostly those we call kupuna, the older generation of elders. We started coordinating the responses of our leaders and immigrant churches, the heads of canoe clubs and governmental departments, Indigenous leaders, and pro-surfers, because that’s what the community here looks like. And what came of it was a few younger leaders — Millennials, so young for our community — were given the elders’ blessing and told, “It’s time for y’all to lead.”
There was Pa’ele [Kiakona], who was a server at a restaurant, and Courtney [Lazo] and Jordan [Ruidas], who were expecting mothers, and they’re the ones who really blew it up. I raised some money to get them on a salary and train them, but they were already community leaders in their own right. So the question was, “How do we maximize their power?”
The first thing we did was needs assessments. Everyone lived in a hotel, but many of the more established charities were opening up in malls 13 or 14 miles away. But our team had iPads and lived in the hotels, too, so while more established groups were getting 100 or so folks signed up, we were getting thousands every day because they were neighbors.
Yeah, you have to be there.
Right, and they all knew each other. We were working on a team with Salesforce — Marc Benioff was helping us back then — and we could figure out people’s needs and direct them to services. There are so many services, but people just lost their homes; they don’t know where to go. So that was the job.
The last question was, “Would you want to get involved down the line with the big decisions that the government will have to make about the priorities of the rebuild?” So once the council started holding hearings about the rebuilding and the policies of reopening and tourism, we were able to turn out hundreds of people instantly. We seized the momentum. We won unanimous support from the council for delaying the reopening of Lahaina to tourists, and we did a big petition delivery to the governor. The governor wasn’t supportive of us at the time, though, and we didn’t ultimately win that one.
From there, it was, “What else do we need?” We needed to house people; that was the main thing. There was also a government guy, Kaleo Manuel [who had been on the state Commission on Water Resource Management until a land developer accused him of delaying water resources during the fire], who we demanded to be reinstated, and we won that. We also had a demand for a billion dollars in direct aid; we won that. But the housing thing was a longer-term flight and went through the legislative session this year. We did this thing called Fishing for Housing, which involved the occupation of Kā’anapali Beach.
I saw your video about that!
That occupation was rough because we lived on a really sandy beach. And it was big. A lot of people came out. But the local news covered it pretty much daily, and it raised a lot of sympathy. We were educating tourists and raising money.
With that, we were able to form a historic partnership. Pa’ele’s uncle is an activist who wants to return water from the hotels to the communities and restore public streams. The unions generally don’t like that kind of stuff in Hawaii, but we were able to bring in ILWU, the hotel union here, and Local 5, another hotel union, which hadn’t partnered with ILWU since 1940. When we came to the legislative session, it was like, “Okay, we have real power now.” The governor came around and committed to passing the bill.
Our theory was that we had to raise a ton of money for direct relief; that was the most important thing, getting direct monetary aid to people. But it was not going to be enough; we weren’t going to raise $10 billion. We could buy one house if we raised a million and a half. Instead, we did this through a [501(c)4 social welfare organization], where you can advocate and contest power where it matters. And we were able to win 50,000 homes instead.
What’s next?
The next steps are on the climate front. The Inflation Reduction Act is a good step; building and electricity, we’re also on track. Agriculture and transportation on a national level are where we need to fill the gaps. Why is Maui growing mono-crops like sugar and coffee for people thousands of miles away? Why can’t we feed our own people? And transportation — when the fires hit, everyone was stuck because of the one-way-in, one-way-out road. Those issues are pertinent not only on the disaster, resiliency, and community infrastructure levels, but also on the mitigation side.
People are also excited about the possibility of microgrids or community-owned energy systems. When we initially had community hubs, members were using Star Link or small solar systems, and locals were like, “Wow, why can’t we do this everywhere?” It’d be way cheaper than fixing the grid at this point.
We have a blank slate to build the future we need. And we’re going to be up against a lot of powerful opponents in the next 10 years.
When we spoke last year, you talked about how rebuilding after the fire was an opportunity to ensure that the people came first and that the forces that contributed to the problem were pushed out of power. Has that effort been successful?
It’s ongoing. Power has many forms: There are the institutional forms, like CEOs and politicians, but there are the shadows — how ideas are organized, industry association gatherings — that are harder to crack. It’s a chess game, and we’re all trying to stay a step ahead.
I think that’s what is critical about our work. If we were to stop, if we could no longer provide our organizers with salaries, they’d have to go back to working two service jobs, and they wouldn’t have the time to compete with full-time lobbyists.
You mentioned other climate disasters early in our conversation. What advice would you give to people in other communities about incorporating mutual aid and holding corporate powers accountable after a catastrophe?
If you come out right away and say, “Hey, this is a climate disaster!” then everyone is like, Oh, an activist. But if you just come out and help and earn people’s trust — that’s what it really takes. Listen to folks.
The thing about climate action and climate solutions is that they have been so polarized over the last few years. I think it’s been moving in our favor. Generally, the population supports us. But those who don’t are much more vocal than they were 10 years ago, and that matters because as soon as they start speaking up, the less political people are just like, “Keep me out of this.” So we have to be careful about how we approach these communities. They’re not thinking about climate; they’re thinking about how to feed their family and how they will get their kids to school or if school is even available. You have to meet them where they are.
Then you go from there. You start to have conversations with them, and they will support getting the polluters out and not being taken advantage of by corporate utilities. You don’t have to talk to them about climate like we always do among advocates; you shouldn’t. If you want to build power in a community, you’ve got to have a different approach. These people, their power is ultimately that they’re survivors, not activists. The public doesn’t perceive them as having an agenda other than just surviving and showing up for their community.
There’s still a lot of work to be done. How do you plan to keep up the forward momentum heading into this fall and the election season?
Visibility and outreach. There’s that old saying that politics is downstream from culture, and our group has been really political, especially during the legislative session. So we’re trying to show up for the community in more direct ways. Today, we paddled with the canoe clubs to honor the first anniversary of the fire. We’re showing up in these more community-based ways so we grow in cultural power, too — not just as an advocacy group, but as a holistic community.
Do you think anything has been missing from the media narrative about Lahaina?
Some of the media that came out today was like, “A year later, people are still without homes.” But if you look at the numbers, the per capita investments from the federal government, and the commitment from FEMA — I mean, it wasn’t great at first, I’ll admit that, but we’ve won quite a bit. We’re winning. The momentum is on our side, and I think it’s important for folks to understand that. They have to feel like it’s worth it and that there’s hope to keep going. I know it’s not the sexiest media narrative and it’s easier to draw criticism, but this is the rise of self-determination. The survivors, to me, are the real story.
And it’s going to take a long time. The fact that it’s like, “Oh, we can’t rebuild a year later.” It was still toxic just a few months ago! There’s debris everywhere. The focus should be less on charity and more on the change and how the power structures have shifted. That’s been really positive.
Do you feel optimistic about the Harris-Walz ticket heading into this fall?
I do. Many reporters have asked me, “Why Harris and not Biden?” Politics is all about coalitions; our movement did a lot of work to become part of the Biden coalition, which was great. But Big Oil was also a part of the coalition he needed to win, so there was always that tension, from my perspective, during his presidency. But with Harris, we’ll have the opportunity to build a dual coalition — perhaps with us and labor, and not Big Oil.

On Alaska’s permitting overhaul, HALEU winners, and Heatmap’s Climate 101
Current conditions: Kansas, Oklahoma, and Arkansas brace for up to a foot of rain • Tropical Storm Juliette, still located well west of Mexico, is moving northward and bringing rain to parts of Southern California • Heat and dryness are raising the risk of wildfire in South Africa.
The Trump administration has started the process to roll back logging protections from more than 44 million acres of national forest land. On Wednesday, U.S. Secretary of Agriculture Brooke Rollins proposed undoing a 25-year-old rule that banned building roads or harvesting timber on federally controlled forest land, much of which is located in Alaska. “Today marks a critical step forward in President Trump’s commitment to restoring local decision-making to federal land managers to empower them to do what’s necessary to protect America’s forests and communities from devastating destruction from fires,” Rollins said in a statement. “This administration is dedicated to removing burdensome, outdated, one-size-fits-all regulations that not only put people and livelihoods at risk but also stifle economic growth in rural America.”
Environmental groups slammed the proposal for jeopardizing wildlife habitats and putting waterways at risk. “Communities depend on clear water filtered by roadless areas, animals depend on the unfragmented habitat that can only exist where there are no roads, and anglers depend on clean water in the streams where trout and salmon swim,” Ellen Montgomery, the director of Environment America’s great outdoors campaign, said in a press release. “We cannot let these essential forests be carved up by roads, obliterated by chainsaws, and contaminated by mines.”
Heatmap’s new Climate 101 series aims, as Heatmap deputy editor Jillian Goodman explained, to be “a primer on some of the key technologies of the energy transition.” That includes “everything from what makes silicon a perfect material for solar panels (and computer chips), to what’s going on inside a lithium-ion battery, to the difference between advanced and enhanced geothermal.”
This might be especially helpful for those still trying to find their way into the climate conversation, but we hope there’s something here for everyone. For instance, did you know that contemporary readers might have understood Don Quixote’s “tilting at windmills” to be an expression of NIMBYism? Well, now you do!
The federal Permitting Council signed a first-of-a-kind memorandum of understanding to work together with Alaska’s government to streamline permitting on critical infrastructure projects across the state. First established in 2015, the agency was designed to improve transparency and speed up the greenlighting of infrastructure approvals. But it had yet to forge such a close pact with an individual state. “Our team is ready to work with Governor Dunleavy to bring Alaska back into the energy spotlight, ending the neglect of the Biden Administration and bringing Alaska’s incredible natural resources to the rest of the world,” Emily Domenech, the Permitting Council’s executive director, said in a statement.
Domenech — a former staffer for House Speakers Kevin McCarthy and Mike Johnson who went on to serve as a senior vice president at Boundary Stone, a firm founded by alumni of the Obama-era Department of Energy — acted as something of a Republican sage for the clean energy industry. In an interview with Heatmap’s Matthew Zeitlin after last November’s election, she urged the industry to forge closer relationships with members of the current congressional majority. “If you ask Republicans to be for or against the IRA as a whole, they’ll be against it,” Domenech said, “But Republicans think about energy as a regional issue. So instead of forcing this one size fits all approach, IRA advocates would be smart to give people room to support only the policies that make the most sense for their state or region.”
The Department of Energy selected another three companies to receive a special kind of nuclear fuel from its growing stockpile. HALEU — pronounced HAY-loo, an acronym for high assay low enriched uranium — is a reactor fuel enriched up to four times as much as traditional reactor fuel. The fuel is needed for all kinds of novel reactor designs, particularly those that use coolants other than water. Until recently, however, Russia’s state-owned Rosatom had enjoyed a virtual monopoly over its global supply. The Biden administration set aside billions for HALEU production. In April, the Trump administration selected five companies to receive some of the government-procured supply, including Westinghouse, Bill Gates’ TerraPower, and the Google-backed Kairos Power. Now the agency has picked another three:
Two firefighters battling the Bear Gulch fire on Washington’s Olympic Peninsula were arrested by federal law enforcement Wednesday. The reason for the arrests is unclear, according to the Seattle Times. Over three hours, federal agents from Border Patrol carried out an “operation on the fire,” demanding identification from members of two private contractor crews who were among the 400 firefighters battling Washington state’s largest active blaze. The Incident Management Team from the National Interagency Fire Center suggested that the action did not interfere with the efforts to tamp down the flames.
The American West is primed for wildfires right now. Following a lull in June and July, Heatmap’s Jeva Lange wrote that “the forecast for the Pacific Northwest for ‘Dirty August’ and ‘Snaptember,’ historically the two worst months of the year in the region for wildfires,” was full of warning signs, including low precipitation and abnormally high temperatures.
Living, gnawing weedwackers.Vesper Energy
The 1.36 million solar panels at Vesper Energy’s Hornet Solar farm in Swisher County, Texas, one of the United States' largest single-phase solar projects, were overgrown with vegetation. So naturally, the company brought in sheep. More than 2,000 white, wooly ovines arrived this month and were allowed to roam the facility’s six square miles. “As Texas continues to lead the nation in solar energy growth, solar grazing highlights how innovation can support rural economies, preserve farmland, and strengthen the state’s reliable energy future,” Vesper said.
Here at Heatmap, we write a lot about decarbonization — that is, the process of transitioning the global economy away from fossil fuels and toward long-term sustainable technologies for generating energy. What we don’t usually write about is what those technologies actually do. Sure, solar panels convert energy from the sun into electricity — but how, exactly? Why do wind turbines have to be that tall? What’s the difference between carbon capture, carbon offsets, and carbon removal, and why does it matter?
So today, we’re bringing you Climate 101, a primer on some of the key technologies of the energy transition. In this series, we’ll cover everything from what makes silicon a perfect material for solar panels (and computer chips), to what’s going on inside a lithium-ion battery, to the difference between advanced and enhanced geothermal.
There’s something here for everyone, whether you’re already an industry expert or merely climate curious. For instance, did you know that contemporary 17th century readers might have understood Don Quixote’s famous “tilting at windmills” to be an expression of NIMYBism? I sure didn’t! But I do now that I’ve read Jeva Lange’s 101 guide to wind energy.
That said, I’d like to extend an especial welcome to those who’ve come here feeling lost in the climate conversation and looking for a way to make sense of it. All of us at Heatmap have been there at some point or another, and we know how confusing — even scary — it can be. The constant drumbeat of news about heatwaves and floods and net-zero this and parts per million that is a lot to take in. We hope this information will help you start to see the bigger picture — because the sooner you do, the sooner you can join the transition, yourself.
Without further ado, here’s your Climate 101 syllabus:
Once you feel ready to go deeper, here are some more Heatmap stories to check out:
The basics on the world’s fastest-growing source of renewable energy.
Solar power is already the backbone of the energy transition. But while the basic technology has been around for decades, in more recent years, installations have proceeded at a record pace. In the United States, solar capacity has grown at an average annual rate of 28% over the past decade. Over a longer timeline, the growth is even more extraordinary — from an stalled capacity base of under 1 gigawatt with virtually no utility-scale solar in 2010, to over 60 gigawatts of utility-scale solar in 2020, and almost 175 gigawatts today. Solar is the fastest-growing source of renewable energy in both the U.S. and the world.
There are some drawbacks to solar, of course. The sun, famously, does not always shine, nor does it illuminate all places on Earth to an equal extent. Placing solar where it’s sunniest can sometimes mean more expense and complexity to connect to the grid. But combined with batteries — especially as energy storage systems develop beyond the four hours of storage offered by existing lithium-ion technology — solar power could be the core of a decarbonized grid.
Solar power can be thought of as a kind of cousin of the semiconductors that power all digital technology. As Princeton energy systems professor and Heatmap contributor Jesse Jenkins has explained, certain materials allow for electrons to flow more easily between molecules, carrying an electrical charge. On one end of the spectrum are your classic conductors, like copper, which are used in transmission lines; on the other end are insulators, like rubber, which limit electrical charges.
In between on that spectrum are semiconductors, which require some amount of energy to be used as a conductor. In the computing context these are used to make transistors, and in the energy context they’re used to make — you guessed it — solar panels.
In a solar panel, the semiconductor material absorbs heat and light from the sun, allowing electrons to flow. The best materials for solar panels, explained Jenkins, have just the right properties so that when they absorb light, all of that energy is used to get the electrons flowing and not turned into wasteful heat. Silicon fits the bill.
When you layer silicon with other materials, you can force the electrons to flow in a single direction consistently; add on a conductive material to siphon off those subatomic particles, and voilà, you’ve got direct current. Combine a bunch of these layers, and you’ve got a photovoltaic panel.
Globally, solar generation capacity stood at over 2,100 terawatt-hours in 2024, according to Our World in Data and the Energy Institute, growing by more than a quarter from the previous year. A huge portion of that growth has been in China, which has almost half of the world’s total installed solar capacity. Installations there have grown at around 40% per year in the past decade.
Solar is still a relatively small share of total electricity generation, however, let alone all energy usage, which includes sectors like transportation and industry. Solar is the sixth largest producer of electricity in the world, behind coal, gas, hydropower, nuclear power, and wind. It’s the fourth largest non-carbon-emitting generation source and the third largest renewable power source, after wind and hydropower.
Solar has taken off in the United States, too, where utility-scale installations make up almost 4% of all electricity generated.
While that doesn’t seem like much, overall growth in generation has been tremendous. In 2024, solar hit just over 300 terawatt-hours of generation in the U.S., compared to about 240 terawatt-hours in 2023 and just under 30 in 2014.
Looking forward, there’s even more solar installation planned. Developers plan to add some 63 gigawatts of capacity to the grid this year, following an additional 30 gigawatts in 2024, making up just over half of the total planned capacity additions, according to Energy information Administration.
Solar is cheap compared to other energy sources, and especially other renewable sources. The world has a lot of practice dealing with silicon at industrial scale, and China especially has rapidly advanced manufacturing processes for photovoltaic cells. Once the solar panel is manufactured, it’s relatively simple to install compared to a wind turbine. And compared to a gas- or coal-fired power plant, the fuel is free.
From 1975 to 2022, solar module costs fell from over $100 per watt to below $0.50, according to Our World In Data. From 2012 to 2022 alone, costs fell by about 90%, and have fallen by “around 20% every time the global cumulative capacity doubles,” writes OWID analyst Hannah Ritchie. Much of the decline in cost has been attributed to “Wright’s Law,” which says that unit costs fall as production increases.
While construction costs have flat-lined or slightly increased recently due to supply chain issues and overall inflation, the overall trend is one of cost declines, with solar construction costs declining from around $3,700 per kilowatt-hour in 2013, to around $1,600 in 2023.
There are solar panels at extreme latitudes — Alaska, for instance, has seen solar growth in the past few years. But there are obvious challenges with the low amount of sunlight for large stretches of the year. At higher latitudes, irradiance, a measure of how much power is transmitted from the sun to a specific area, is lower (although that also varies based on climate and elevation). Then there are also more day-to-day issues, such as the effect of snow and ice on panels, which can cause issues in turning sunlight into power (they literally block the panel from the sun). High latitudes can see wild swings in solar generation: In Tromso, in northern Norway, solar generation in summer months can be three times as high as the annual average, with a stretch of literally zero production in December and January.
While many Nordic countries have been leaders in decarbonizing their electricity grids, they tend not to rely on solar in that project. In Sweden, nuclear and hydropower are its largest non-carbon-emitting fuel sources for electricity; in Norway, electricity comes almost exclusively from hydropower.
There has been some kind of policy support for solar power since 1978, when the Energy Tax Act provided tax credits for solar power investment. Since then, the investment tax credit has been the workhorse of American solar policy. The tax credit as it was first established was worth 10% of the system’s upfront cost “for business energy property and equipment using energy resources other than oil or natural gas,” according to the Congressional Research Service.
But above that baseline consistency has been a fair amount of higher-level turmoil, especially recently. The Energy Policy Act of 2005 kicked up the value of that credit to 30% through 2007; Congress kept extending that timeline, with the ITC eventually scheduled to come down to 10% for utility-scale and zero for residential projects by 2024.
Then came the 2022 Inflation Reduction Act, which re-instituted the 30% investment tax credit, with bonuses for domestic manufacturing and installing solar in designated “energy communities,” which were supposed to be areas traditionally economically dependent on fossil fuels. The tax then transitioned into a “technology neutral” investment tax credit that applied across non-carbon-emitting energy sources, including solar, beginning in 2024.
This year, Congress overhauled the tax incentives for solar (and wind) yet again. Under the One Big Beautiful Bill Act, signed in July, solar projects have to start construction by July 2026, or complete construction by the end of 2027 to qualify for the tax credit. The Internal Revenue Service later tightened up its definition of what it means for a project to start construction, emphasizing continuing actual physical construction activities as opposed to upfront expenditures, which could imperil future solar development.
At the same time, the Trump administration is applying a vise to renewables projects on public lands and for which the federal government plays a role in permitting. Renewable industry trade groups have said that the highest levels of the Department of Interior are obstructing permitting for solar projects on public lands, which are now subject to a much closer level of review than non-renewable energy projects.
Massachusetts Institute of Technology Researchers attributed the falling cost of solar this century to “scale economies.” Much of this scale has been achieved in China, which dominates the market for solar panel production, especially for export, even though much of the technology was developed in the United States.
At this point, however, the cost of an actual solar system is increasingly made up of “soft costs” like labor and permitting, at least in the United States. According to data from the National Renewables Energy Laboratory, a utility-scale system costs $1.20 per watt, of which soft costs make up a third, $0.40. Ten years ago, a utility-scale system cost $2.90 per watt, of which soft costs was $1.20, or less than half.
Beyond working to make existing technology even cheaper, there are other materials-based advances that promise higher efficiency for solar panels.
The most prominent is “perovskite,” the name for a group of compounds with similar structures that absorb certain frequencies of light particularly well and, when stacked with silicon, can enable more output for a given amount of solar radiation. Perovskite cells have seen measured efficiencies upwards of 34% when combined with silicon, whereas typical solar cells top out around 20%.
The issue with perovskite is that it’s not particularly durable, partially due to weaker chemical bonds within the layers of the cell. It’s also more expensive than existing solar, although much of that comes down inefficient manufacturing processes. If those problems can be solved, perovskite could promise more output for the same level of soft costs as silicon-based solar panels.
