New data provided exclusively to Heatmap shows just how complicated it is to get money where it needs to go.
By the numbers, a new federal program designed to give low-income communities access to renewable energy looks like a smashing success. According to data provided exclusively to Heatmap, in its first year, the Low-Income Communities Bonus Credit Program steered nearly 50,000 solar projects to low-income communities and tribal lands, which are together expected to produce more than $270 million in annual energy savings.
But those topline numbers don’t say anything about who will actually see the savings, or how much the projects will benefit households that have historically been left behind. In reality, the majority of the projects — about 98% — were allocated funding simply for being located in low-income communities, with no hard requirement to deliver energy or financial savings to low-income residents.
A closer look at the data reveals a more complicated success story. While the program did make some clear strides in bridging the solar inequality gap, other factors — including the language in the law that created it — are also holding it back.
The Low-Income Communities Bonus Credit Program came out of the Inflation Reduction Act in August 2022. Though the goal is to increase solar access for low-income households, it’s not actually a tax credit for low income households. It’s for small wind and solar developers — and beginning in 2025, developers of other types of clean energy — whose projects meet certain criteria.
The law caps the total amount of energy the program can support at 1.8 gigawatts per year, and developers have to apply and get their project approved in order to claim funds. To be eligible, a project must produce less than 5 megawatts of power and fall under one of four categories: It must be located in a low-income community, be built on Indian land, be part of an affordable housing development, or distribute at least half its power (and guaranteed bill savings) to low-income households. The first two categories qualify for a 10% credit; the second two, which stipulate that at least some financial benefits go to low-income residents, qualify for 20%. In both cases, the credit can be stacked on top of the baseline 30% tax credit for clean energy projects that meet labor standards, meaning it could slash the cost of building a small solar or wind farm in half.
Each of these provisions has the potential to address at least some of the barriers disadvantaged communities face in accessing clean energy. Low-income homeowners may not have the money for a down payment for rooftop solar or the credit to find financing, for instance. But by giving developers a tax credit for projects located in low-income communities, solar leasing programs, in which homeowners lease panels from a third party in exchange for energy bill savings, now have an incentive to expand into these neighborhoods, and potentially offer lower lease rates. The program helped fund nearly 48,000 residential solar projects in the first year.
Tribal lands, meanwhile, account for more than 5% of solar generation potential in the U.S., but are still a largely untapped resource, for reasons including lack of representation in utility regulatory processes, complex land ownership structures, and limited tribal staff capacity. The program gives outside developers additional incentive to work through the challenges, and it also earmarks funds for tribe-owned development. Crucially, the IRA also opened the door for tribes, as well as other tax-exempt entities, to utilize clean energy incentives and receive a direct payment equal to the tax credits. The program supported 96 solar projects on tribal lands in the first year.
The third category attempts to overcome the famous “split incentive” problem for low-income renters whose landlords have little reason to spend money on a solar project that primarily benefits tenants. The program helped finance 805 solar projects on low-income residential buildings, where the developers are required to distribute at least 50% of the energy savings equitably among tenants.
Lastly, while renters in some states can subscribe to community solar projects, which offer utility bill credits in exchange for a small subscription fee, the subscriptions can be scooped up by wealthier customers if there’s no low-income requirement. The program sponsored 319 community solar projects where at least half the capacity had to go to low-income residents and offer at least 20% off their bills.
U.S. Deputy Secretary of the Treasury Wally Adeyemo declared the program a success. “These investments are already lowering costs, protecting families from energy price spikes, and creating new opportunities in our clean energy future,” he said.
Despite overwhelming demand during the four-month application period, however, the program ended up with capacity to spare. Although applications totaled more than 7 gigawatts, ultimately, the Department approved just over 49,000 projects equal to about 1.4 gigawatts, or roughly enough to power 200,000 average households. All of it was solar.
The gap between applications and awarded projects has to do with the program’s design. The Treasury divided the 1.8 gigawatt cap between the four categories, setting maximum amounts that could be awarded for each one. Within the four categories, the awards were further divided, with half set aside for applicants that met additional ownership or geographic criteria, such as tribal-owned companies, tax-exempt entities, or projects sited in areas with especially high energy costs relative to incomes.
For example, 200 megawatts were earmarked for Indian lands, with half reserved for applicants meeting those additional criteria, but only 40 megawatts were awarded. The fourth category, meanwhile, which was designed to encourage community solar development, was oversubscribed.
Since tax data is confidential, the Treasury Department could not share much detail about these projects, including where, exactly, they were, who developed them, or who will benefit from them. A map overview shows a concentration of awards across the sunbelt, with Illinois, New York, Maine, Massachusetts, and Puerto Rico also seeing a lot of uptake.
IRS, RAAS, Statistics of Income, August 2024
I reached out to more than a dozen nonprofits, tribal organizations, and other groups who advocate for or develop clean energy projects benefiting low-income communities to find examples of what the program was actually funding. The first person I was connected with was Richard Best, the director of capital projects and planning for Seattle Public Schools, who got a 10% tax credit for solar arrays on two new schools under construction in low-income neighborhoods. While the school system already planned to put solar on these schools, Best said the tax credits helped offset increased construction costs due to supply chain interruptions, preventing them from having to make compromises on design elements like classroom size.
“It's not insignificant,” he told me. “The solar array at Rainier Beach High School is in excess of a million dollars — just the rooftop solar array. That's $400,000 [in tax credits]. So these are significant dollars that we're receiving, and we're very appreciative.”
Jody Lincoln, an affordable housing development officer for the nonprofit ACTION-Housing in Pittsburgh, Pennsylvania, got a 10% tax credit to add solar to a former YMCA that the group recently converted to a 74-unit apartment building. The single room occupancy rental units serve men who are coming out of homelessness or incarceration. Lincoln told me the building operates “in the gray,” and that any cost saving measures they can make, including the energy savings from the solar array, enable it to continue to operate as affordable housing. When I asked if they could have built the solar project without access to the IRA’s tax credits, she didn’t hesitate: “No.”
These two examples show the program has potential to deliver benefits to low-income communities, even in cases where the energy savings aren’t going directly to low-income residents.
I also spoke with Alexandra Wyatt, the managing policy director and counsel at the nonprofit solar company Grid Alternatives. She told me Grid partnered with for-profit solar developers, such as the national solar company SunRun, who were approved for the tax credit bonus for rooftop solar lease projects on low-income single-family homes. In these cases, Grid helped pull together other sources of funding like state incentives for projects in disadvantaged communities to pre-pay the leases so that the homeowners could more fully benefit from the energy bill savings.
It’s unlikely that all of the nearly 48,000 residential rooftop solar projects in low-income communities that were approved for the credit in the first year had such virtuous outcomes. It’s also possible that projects installed on wealthier homeowners’ roofs in gentrifying neighborhoods were subsidized. In an email to me, a Treasury spokesperson said the Department recognizes that “simply being in a low-income community does not mean low-income households are being served,” and that it was required by statute to include this category. It was still the agency’s decision, however, to allocate such a large portion of the awards, 700 megawatts, to this category — a decision that some public comments on the program disagreed with.
Wyatt applauded the Treasury and the Department of Energy, which oversees the application process, for doing “an admirable job on a tight timeframe with a challenging program design handed to them by Congress.” She’s especially frustrated by the 1.8 gigawatt cap, which none of the other renewable energy tax credits have, and which changes it into a competitive grant that’s more burdensome both for developers and for the agencies. It adds an element of uncertainty to project finance, she said, since developers have to wait to see if their application for the credit was approved.
Wendolyn Holland, the senior advisor for policy, tax and government relations at the Alliance for Tribal Clean Energy told me there was tons of interest among indigenous communities and tribal clean energy developers in taking advantage of the IRA programs, but it wasn’t really happening. Holland cited challenges for tribes reaching the stage of “commercial readiness” required to apply for federal funding. Tribal developers have also said they are limited by the lack of transmission on tribal lands. When I asked the Treasury about the paltry number of projects on Indian Lands, a spokesperson said it was not for lack of trying. The Department and other federal agencies have conducted webinars and other forms of outreach, they said, through which they’ve heard that many tribes are struggling to access capital for energy projects, and that development on Indian lands has “unique challenges due to the history of allotment of Indian lands and status of some land as federal trust land.”
Holland is optimistic that things will change — in December, Biden issued an executive order committing to making it easier for tribes to access federal funding. The Alliance also recently petitioned the Federal Energy Regulatory Commission to address barriers for tribal energy development in its new rules that are supposed to get more transmission built.
The unallocated capacity from 2023 was carried over to the next year’s round of funding, so it wasn’t lost. But a dashboard tracking the second year of the program looks like it's following a similar pattern. While the community solar-oriented category, which was increased to allow for 900 megawatts, is nearly filled up, the tribal Lands category, which kept its 200 megawatt cap, has received applications to develop less than a sixth of that.
Wyatt said that so far, she does think the bonus credit has been successful in spurring good projects that might not otherwise have happened. Still, it will probably take a few years before it will be possible to assess how well it’s working. The good news is, as long as it doesn’t get repealed, the program could run for up to eight more years, leaving plenty of time to improve things. It’s already set to change in one key way. Beginning in 2025, it becomes tech-neutral, meaning that developers of small hydroelectric, geothermal heating or power, or nuclear projects, will be able to apply. (When asked why no wind projects were approved to date, a spokesperson for the Treasury said taxpayer privacy rules meant it couldn’t comment on applications, but they added that wind projects tend to be larger than 5 megawatts and take longer to develop.)
One thing is for sure, despite the heavy administrative burden of screening tens of thousands of applications, the agencies involved are clearly committed to implementing the program.
“I’m definitely pleased that they managed to get the program up and running as quickly as they did,” Wyatt told me. “I mean, it's kind of lightning speed for the IRS.”

Current conditions: Severe flooding in west and central Africa has displaced nearly one million people • Brazil is choking on wildfire smoke that can be seen from space • Shanghai was struck by Typhoon Bebinca, the strongest storm to hit the city in 75 years.
Flooding across central and eastern Europe has killed at least 10 people and forced tens of thousands to evacuate. Since late last week, the slow-moving Storm Boris has dumped huge amounts of rain on the region, causing dams to burst and rivers to overflow and inundating communities in Austria, Poland, Hungary, Romania, the Czech Republic, and Slovakia. Parts of eastern Germany are also on alert. In the Austrian capital of Vienna, the Wien River’s water level rose from about 20 inches to more than seven feet in the course of a day. Meanwhile some mountain regions received more than three feet of snow. In Poland, Prime Minister Donald Tusk today declared a state of natural disaster. According to the Red Cross Red Crescent Climate Center, the floods could be the worst since 2002.

The European Environment Agency has warned that flooding is likely to be “one of the most serious effects from climate change in Europe over coming decades.”
Both U.S. coasts are experiencing wild weather but of very different kinds. The National Hurricane Center issued tropical storm warnings for the Carolinas as “Tropical Cyclone Eight” approaches with 50 mph winds. The system could bring up to 8 inches of rain and flash floods. Meanwhile, on the West Coast, parts of California are expecting snow. The state issued its earliest snow advisory in 20 years for the Sierra Nevada mountain range, where up to 4 inches could fall through Monday afternoon.
With COP29 now less than two months away, key players are working hard to lay the groundwork for the outcomes they’d like to see from the annual climate summit. Here are some recent developments:
A recent study finds that the risk of weather-related supply chain disruptions will rise more in the U.S. than in any other country over the next 15 years. This is because the country is starting from a pretty low baseline risk, thanks to the interconnectivity of all the states. “If a heatwave or period of extreme rainfall hits one part of the U.S., it is easily able to import goods and services from other areas,” CarbonBrief explained. But the risk won’t stay that low forever, and indeed the authors note that the U.S. “is subject to the strongest relative increases in consumption risks” through 2040 as weather shocks increase.
Tesla sold 5,175 Cybertrucks in July, according to data from S&P Global Mobility. Sales of all other EV pickups combined during that month reached 5,546. Jesse Jenkins, a Princeton professor and energy systems engineering expert (and co-host of Heatmap’s climate podcast Shift Key) predicted back in December that the Cybertruck would be crushed by EV pickup rivals like the Ford F-150 Lightning and Rivian’s R1. But now…
The U.S. Postal Service recently started rolling out its Next Generation Delivery Vehicles — most of which will be electric. The vehicles may not be beautiful, but as Paul Waldman argued for Heatmap, if you want to normalize EVs, “what better way than to have a funky-looking EV rolling down your street every day, delivering mail to your door?”
Isometric is trying to become the most trusted name in the scandal-plagued carbon market.
Regulations are probably coming for the scandal-plagued voluntary carbon market. After years of mounting skepticism and reports of greenwashing, governments are now attempting to rein in the historically unchecked web of platforms, registries, protocols, and verification bodies offering ways to offset a company’s emissions that vary tremendously in price and quality. Europe has developed its own rules, the Carbon Removal Certification Framework, while the Biden administration earlier this year announced a less comprehensive set of general principles. Plus, there are already mandatory carbon credit schemes around the world, such as California’s cap-and-trade program and the E.U. Emissions Trading System.
“The idea that a voluntary credit should be a different thing than a compliance credit, obviously doesn’t make sense, right?” Ryan Orbuch, Lowercarbon Capital’s carbon removal lead, told me. “You want it to be as likely as possible that the thing you’re buying today is going to count in a compliance regime.”
That’s where the carbon credit certification platform Isometric comes into play. Founded in 2022, the startup raised $25 million in its seed round last year, co-led by Lowercarbon and Plural, a European venture capital firm. It has created a rigorous, scientifically-driven standard for carbon removal credits, with the intention of becoming the benchmark that buyers, sellers, and other stakeholders can coalesce around. So whenever federal standards or compliance regimes do kick in, there will be no doubt whether Isometric-verified credits are up to snuff.
“Isometric was basically founded to say, look, the long-term solution here is obviously government and regulation, but in the meantime, this is too important to let the market just keep doing it like this,” Lukas May, chief commercial officer at Isometric, told me. He believes that the government’s role in the carbon market should mirror the financial sector, but instead of preventing insider trading or predatory lending, federal regulators would make high-level determinations on things like what types of credits count and how long carbon must be locked away to count as “permanent removal.” Platforms like Isometric (often referred to as registries) could then focus on setting more granular, scientifically specific requirements for particular methods of carbon removal.
The startup aims to separate itself from existing registries, which include Puro.earth, Verra, and the Gold Standard, in two big ways.
First is just a focus on science. May said that 15 of Isometric’s first 25 hires were scientists. Today, the company’s chief scientist is Jennifer Wilcox, who recently left her position on the leadership team at the Office of Fossil Energy and Carbon Management, housed within the U.S. Department of Energy. Other registries, he told me, are “filled with NGO types” and “policy people” who lack the technical background to, say, evaluate what types rock formations are best for the geological sequestration of bio-oil or how CO2 fluxes in the soil impact enhanced rock weathering. These types of in-the-weeds analyses are integral to establishing stringent protocols to validate the amount of carbon that’s actually been removed.
Additionally, May, Orbuch, and Khaled Helioui, a partner at Plural who led the firm’s investment in Isometric, all said the company fixes a key flaw in the voluntary carbon market —- alignment of financial incentives. Traditionally, carbon removal suppliers pay registries to certify their credits, which creates an incentive for registries to overlook lax standards. But Isometric is instead paid a flat fee by the buyers for performing verification work on a per-ton basis.
This year, Isometric verified its first credits ever, from the carbon removal companies Vaulted Deep, which collects sludgy, organic waste and deposits it underground, and Charm Industrial, which injects processed biomass into abandoned oil and gas wells. Credits from these two suppliers were sold to Frontier, the carbon-removal initiative led by the payments firm Stripe. Just last week, Frontier identified Isometric as its first and only leading credit issuer.
“What makes Isometric stand out is they’re explicitly focused on durable CDR [carbon dioxide removal],” Joanna Klitzke, Frontier’s procurement and ecosystem strategy lead, told me. “Durable” refers to the fact that Isometric’s projects must sequester CO2 for 1,000 years or more. “They’re building tech products that make data and reporting particularly easy for suppliers and for credit management,” she added.
Everyone is essentially trying to avoid another scandal like the one that engulfed rainforest carbon offsets, which were found to be largely worthless. The industry has thus been shifting away from more nebulous carbon offsets, which seek to avoid future emissions by preventing deforestation or funding renewables development, and towards more concrete, but often more expensive, forms of carbon removal — think direct air capture, enhanced rock weathering, or biomass carbon removal and storage, all of which have seen a boom in investment.
“As carbon removal was emerging as a new and potentially very exciting way to do this stuff, potentially more measurable and more rigorous, we couldn’t just sit and watch the same registries do the same thing,” May told me, saying doing so would “destroy trust in the carbon removal industry before it’s even off the ground.”
In a past life, Isometric’s founder and CEO, Eamon Jubbawy, founded a digital identity verification company for the financial services industry. This gave investors confidence that he could bring his expertise in trust-building and verification services to the carbon removal space.
“It’s not a like for like, but there’s a lot of overlap in terms of actually introducing efficiency, effectiveness, and having technology really open a market,” Plural’s Helioui told me. “This is not an endeavor or an opportunity where I would have been necessarily that keen to back a first-time founder, just because of the complexity of what you need to manage,” he said. “We’re really talking about market creation.”
But May doesn’t expect Isometric to totally dominate other registries. Just like there are many private banks, May envisions an “ecosystem of high quality registries,” eventually unified around a set of federal guardrails. Until then, he believes Isometric’s role is to “set a bar that is so high that the expectation and norm in the market shifts,” thus avoiding a race to the bottom where companies are able to greenwash their image with cheap, low-quality credits.
Now, not every company can afford the highest quality credits. And because of Isometric’s 1,000-year storage requirement, many cheaper, nature-based projects, such as reforestation, are excluded from its registry, even though there’s still demand for them. Orbuch told me that Isometric will continue adding guidelines for different carbon removal pathways, as it recently did for biochar, a charcoal-like brick that locks up carbon contained within biomass.
It’s still early days, and there’s plenty of room for Isometric to grow alongside the market. After all, it’s only issued 5,350 carbon removal credits to date, while nearly two billion credits have been issued in the voluntary carbon market overall.
“The whole industry needs to be scaling up,” May told me. “So we need to, in 10 years time, be, you know, issuing and verifying hundreds of millions, if not billions, of credits annually.”
On the U.S. Postal Service’s wonderfully weird shift to electric cars
When you think of a gas-guzzler, what comes to mind is probably a gigantic pickup like the Ram 1500 TRX, which gets a combined 12 miles per gallon, or a sports car like the Ferrari Daytona, which manages a less-than-impressive 13 mpg. But you may not think about a vehicle you’ve likely seen a thousand times: the small trucks driven by most local mail carriers, known as the Grumman Long Life Vehicle. They lived up to their name, since they’ve been in service since the mid-80s; the newest of them were built 30 years ago. But they get an abysmal 9 miles per gallon, burning fuel by the tankful and spewing emissions as they go about their appointed rounds.
So after a long and winding journey to a replacement for the LLV, the first of the Postal Service’s Next Generation Delivery Vehicles — most of which will be electric — just hit the road. And they are beautiful.
Oshkosh Defense
This may not be a widely shared opinion. Indeed, some will find the NGDV downright ugly, and they won’t exactly be wrong. But the new postal truck’s weird appearance — many have remarked that it looks like a duck, or something from a Richard Scarry book — is what, I predict, will make it iconic. In addition to bringing a touch of whimsy to your neighborhood, the NGDV will advance the cause of vehicle electrification much more than you might expect.
Postal delivery vehicles were always a no-brainer for electrification: They do a lot of stopping and starting, they follow fixed routes so they can charge at a single location, and since the existing fleet uses so much gas, electrifying them will make a real dent in the nation’s emissions.
The old trucks didn’t just add to our nation’s carbon emissions, they got no love from the workers who drove them. If you’ve noticed your mail carrier sweating profusely as they bring letters to your door in the summer, it’s not just because they have to carry that heavy bag up and down the street. It’s also because their creaky, uncomfortable vehicles have no air conditioning. In 2024.
“It felt like heaven blowing in my face,” said one carrier after trying out the NGDV, which does indeed have air conditioning, along with many of the safety features, including backup cameras, antilock brakes, and airbags, that are common in modern cars but the LLVs lacked. The new truck also looks unusual because it solves many of the problems the old vehicles pose for letter carriers. The truck had to be tall enough to allow them to stand up in the back, so they won’t have to hunch over the way they do now. It had to be low to the ground so they can get in and out easily dozens of times in a shift. It had to have a big enough windshield for the shortest and tallest carriers to see out comfortably.
Oshkosh Defense
All that meant that the NGDV wound up looking like no other vehicle. Once they are fully deployed — the current plan is to put 60,000 into service over the next few years — their unique profile will become familiar to everyone. And it’s important that this strange electric vehicle will be associated with the Postal Service. Because people love the Postal Service.
That might be a surprise given familiar complaints about lines at the post office. But it turns out that when surveys are taken, the Postal Service always ranks at or near the top of public approval among federal agencies. A recent Pew Research poll put the USPS’s approval at 72%, behind only the National Park Service. Gallup polls show them at the top. A 2020 survey by the department’s Inspector General found 91% of respondents saying they had a positive view of the USPS.
Perhaps people have a sense that what the Postal Service accomplishes is nothing short of miraculous. They move over 300 million pieces of mail every day, and deliver to 167 million addresses. They’ll pick up a letter at your door, take it anywhere in the country by land or air or water, and deliver it right to your Aunt Myrtle in the space of a few days — and not for $50 or $100, but for 73 cents. It costs the same whether that letter is going to Atlanta or Alakanuk. As U.S. law states, the purpose of the Postal Service is “to bind the Nation together through the personal, educational, literary, and business correspondence of the people.” The USPS is nothing less than a national treasure.
Maybe people appreciate that, or maybe it’s just that most of us like getting mail, and our mail carriers are part of our communities (and usually friendly). In any case, the new electric vehicles will be associated with all the positive feelings people have about the USPS.
Which is why it’s fine — and maybe even better — that the NGDV is odd-looking, or even ugly (but in a charming way). One prevailing theory about EV adoption — advanced by Tesla’s Elon Musk and embodied in other vehicles like the Ford F-150 Lightning — is that the way to get people to buy EVs is to make EVs that are cool. It’s a valid perspective, but another way to think about the long-term goal of transportation electrification is that EVs ought to be in as many places and as many forms as possible. If you want to normalize them, what better way than to have a funky-looking EV rolling down your street every day, delivering mail to your door?
It may be a while before you spot an NGDV in your neighborhood; among other things, it will take time to install the charging infrastructure at all the postal facilities necessary to electrify the entire delivery fleet. After all, one of the things that makes the Postal Service such a vital part of our national life is that it touches Americans, and delivers to them, no matter how far-flung they are. At least at first, we may be more likely to see electric delivery vehicles in big cities than in remote rural areas.
But before long, the NGDV could become the most widely recognized EV in the country, and one that people associate with service, community, efficiency, and patriotism. And yes, they look weird. Which is part of what makes them great.
