Picture a modest house on a street where electricity bills arrive every month like a small emergency. The roof holds no solar panels, even though the sun beats down just as hard here as it does across town on the bigger homes that already have them. For a few years, a federal program set out to change that picture for nearly a million American families. Then, just as it was working, it stopped.
The neighborhood that solar forgot
Clean energy has never been distributed equally. Disadvantaged communities have far fewer solar panels on their rooftops than higher-income areas, even when they face the highest energy burdens.
For Native American tribes, the gap is especially stark. Indigenous families face a significantly higher energy burden on average than other households, according to the Department of Energy.
The reason is straightforward: the upfront cost of going solar has always been a wall. Renters, tribal households and low-income homeowners were simply left out of a technology that was supposed to belong to everyone.
That was precisely the problem one sweeping federal program was designed to fix, and for a while, it genuinely looked like it was going to.
A billion-dollar bet on every rooftop
The EPA announced 60 organizations that would receive a combined $7 billion in grants to bring residential solar to low-income neighborhoods across the country.
By funding programs that provide rooftop solar panels, batteries to store solar energy, and community solar farms, the EPA expected to help more than 900,000 low-income households reduce pollution and reduce bills.
All told, the program was expected to prevent over 30 million metric tons of carbon dioxide from ever entering the atmosphere while also creating 200,000 jobs.
Harris County, Texas, which encompasses Houston, was awarded $249 million to provide distributed solar and battery storage to disadvantaged communities. The award included workforce training for low-income residents and minority and women-owned businesses, making it one of the biggest single awards in the country.
The ocean nobody saw coming
Here is the part that surprises almost everyone: alongside the push to make solar affordable on land, researchers are pursuing something happening far beneath the surface of the sea.
Researchers are now studying how to power underwater robots with solar energy, specifically, how to make solar cells viable for autonomous underwater vehicles (AUVs) and remotely operated vehicles. Scientists at NYU Tandon School of Engineering are developing alternative power solutions for these vehicles, with the goal of enabling unrestricted diving patterns and eliminating the need to resurface to recharge.
Solar power is a potential solution: sunlight can penetrate surprisingly deeply into the oceans. Visible light, particularly in the green to blue part of the spectrum, can reach waters up to 50 metres deep. However, the silicon photovoltaic cells used on land are optimised for the red part of the spectrum, which means underwater solar requires purpose-built technology rather than a simple transfer of rooftop hardware.
Improved understanding of marine ecosystems is one of the goals driving this research, and continuous solar-powered monitoring stations represent a promising tool for long-term environmental observation.
How Solar for All was ended
The program, officially called Solar for All, had already survived one near-death experience when federal funding was frozen in early 2025. A federal court ruled in April 2025 that the EPA could not freeze existing Solar for All contracts, and new and existing solar programs were expected to resume as planned.
That relief did not last. The Environmental Protection Agency announced it was terminating the program entirely, cutting off renewable and affordable energy access for low-income communities mid-stride.
On August 7, 2025, Administrator Zeldin announced the agency would no longer implement the program. The One Big Beautiful Bill Act, signed into law on July 4, 2025, repealed the Greenhouse Gas Reduction Fund, which Zeldin cited as removing the EPA’s statutory authority to administer Solar for All and its remaining funds. That termination is now being contested in court: multiple grant recipients and advocacy groups have sued the EPA, arguing the rescission was unlawful because Congress had already obligated the funds.
For tribal communities already a year into their projects, the timing felt like a particular betrayal. “Tribes have always endured broken promises for many generations at the federal level, and this is just another broken promise,” Cody Two Bears told CBS News.
The program had delivered genuine early results too. Indigenized Energy had completed one of the first Solar for All projects in the country earlier in 2025, despite setbacks when funding had been frozen.
What the sun still promises
Solar energy itself has not retreated. Costs keep falling, and the technology keeps finding new places to go, from offshore wind and solar infrastructure reshaping marine ecosystems, to the rooftops of homes that have never had access before.
Researchers tracking wildlife drawn to solar farms after dark have found that these installations create unexpected living corridors in places once written off as wasteland.
State-level programs and nonprofits are working to fill the gap left by the federal withdrawal, and community solar models let renters subscribe to a shared array without ever touching a rooftop.
The story of Solar for All is genuinely unresolved, and different observers draw opposite conclusions about why it ended. What is harder to dispute is what the program actually did while it ran: it pointed the sun at streets that had been in the shade for too long, and it showed that the technology works just as well there as anywhere else.
The light did not disappear. It just needs a new path to the people who need it most.
