The end of the solar tax credit is not the end of the solar industry. Photo by Kindel Media/Pexels

Texas still has its best solar days ahead of it, even as federal tax credit sunsets

Guest Column

If you follow energy policy, you already know that Congress repealed the 30% residential solar tax credit. This poses a significant challenge for continued growth in the market. It also provides an opportunity for the industry to grow in a smart, consumer-friendly way. That’s why in Texas, the story is what happens next: The state and the market are continuing to make going solar much simpler, better, and cheaper.

Policies are moving in the right direction. For example, starting this month, a bipartisan permitting reform takes effect that will cut red tape for home solar and batteries. It lets licensed third-party professionals review plans and perform inspections, requires agencies to post standardized rules and fees online, and allows homeowners to start work once those third-party approvals are submitted. It also shifts negligence liability to the third-party reviewer, thereby reducing municipal risk while accelerating safe, code-compliant installs. In plain English: fewer bottlenecks, faster installs, and lower “soft costs.”

As a result, Houston is already piloting the National Renewable Energy Lab’s free SolarAPP+ to auto-approve standard solar designs, which cuts roughly 12 days from typical timelines. Independent analyses estimate that these automated permitting rules could trim rooftop solar costs by thousands. In other words, even small, costless policy changes like this can save you almost as much money as the huge solar tax credit did, and these great reforms are happening all the time, and they make the process much more convenient and reliable.

While Texas is making solar simpler, it’s also helping consumers have a good experience when going solar. As of this month, Texas law now also requires solar salespeople to register with the Texas Department of Licensing and Regulation. The same bill standardizes contracts and provides for mandatory disclosures of upfront cost and financing terms. The whole solar industry benefits when customers have a good solar experience. Word of mouth is vital to keeping solar shining.

There's yet another pro-solar Texas law that's also going into effect this month: in addition to SB 1202 (streamlining solar permits) and SB 1036 (regulating solar sales tactics), the legislature is also supporting the dissemination of information about your options when going solar via SB 1697. You can read more about these three brand-new pro-solar state laws here.

The end of the solar tax credit is not the end of the solar industry. Far from it.

EPA scraps $7B solar program, stripping Texas of hundreds of millions in clean energy funds

funding cut

The U.S. Environmental Protection Agency is ending a $7 billion Biden-era program that was supposed to enable low-income Americans to access affordable solar power. The program, which EPA Administrator Lee Zeldin called a “boondoggle,” would have benefited more than 900,000 U.S. households.

In line with the EPA’s action, the Lone Star State is losing a $249.7 million grant awarded last year to the Harris County-led Texas Solar for All Coalition. The grant money would have equipped more than 46,000 low-income and disadvantaged communities and households in Texas with residential solar power. The nonprofit Solar United Neighbors organization said Texas had already begun to roll out this initiative.

Also slipping out of Texas’ hands are:

  • A more than $156 million 19-state grant awarded to the Clean Energy Fund of Texas in partnership with the Bullard Center for Environmental and Climate Justice at Houston’s Texas Southern University. The Clean Energy Fund is a Houston-based “green bank” that backs investments in solar and wind power.
  • Part of a $249.3 million multistate grant awarded to the Community Power Coalition’s Powering America Together Program. The nonprofit Inclusive Prosperity Capital organization leads the coalition.
  • Part of a $249.8 million multistate grant awarded to the Solar Access for Nationwide Affordable Housing Program, led by the nonprofit GRID Alternatives organization.

In a post on the X social media platform, Zeldin said the recently passed “One Big Beautiful Bill” killed the Greenhouse Gas Reduction Fund, which would have financed the $7 billion Solar for All program.

“The bottom line is this: EPA no longer has the statutory authority to administer the program or the appropriated funds to keep this boondoggle alive,” Zeldin said.

Anya Schoolman, executive director of Washington, D.C.-based Solar United Neighbors, accused the EPA of illegally terminating the Solar for All program. She said ending the program “harms families struggling with rising energy costs and will cost us good local jobs.”

U.S. Sen. Bernie Sanders, a Vermont independent, joined Schoolman in alleging the EPA’s “outrageous” action is illegal. Sanders introduced the legislation that established the Solar for All program.

The senator lashed out at President Trump for axing the program in order “to protect the obscene profits of his friends in the oil and gas industry.”

Houston rolls out discounts on solar installation to move the needle on lower-carbon options

expert panels

A city of Houston initiative is offering a discounted rate for solar panel installation for homeowners and small businesses.

This year's Solar Switch Houston deal produces an average savings of $5,315 for each Houstonian who registers with Solar Switch, according to a news release from the city, which partnered with the nonprofit Solar United Neighbors. It's the third time the organizations have teamed up to provide the discount.

“We had great success with the first two rounds of Solar Switch Houston where residents were provided with a trusted information source and a substantial group discount,” City of Houston Interim Chief Resilience and Sustainability Officer Nicholas Hadjigeorge says in the release. “I am confident that the savings attained in the third round of the program will play a crucial role for residents deciding if solar is the right choice."

The organization vetted solar installers, factoring in "product quality, warranties, company financial stability, and history of customer satisfaction," per the news release. These installers then participated in a reverse auction to provide the discounted services. Those interested in learning more can head to SolarSwitch.com/Houston.

"Everyone deserves to benefit from generating their own solar energy. That’s why we designed Solar Switch – to make installing solar affordable and straightforward for more Houstonians than ever before," America Garcia, Texas program director for Solar United Neighbors, says in the release. "I’m excited to see how much we can broaden the reach and benefits of solar group buying with the continuation of Solar Switch Houston."

Houston charges up new program to help locals buy and install affordable solar panels

sunny days

Alternative-energy-seeking locals now have a sunny way to buy into a solar. The City of Houston has launched Texas Solar SwitchHouston, a new program aimed at helping Houstonians purchase and install rooftop solar panels and battery storage.

In partnership with Solar United Neighbors, the Solar Switch program offers hassle-free way to purchase solar panels by creating a massive, group discount for residents, be it home or small business needs.

This comes with the new Inflation Reduction Act’s clean energy incentives and is part of the City of Houston's Climate Action Plan goal to generate 5 million MWh per year of local solar, per a press release. Customers who install solar also receive a 30-percent tax credit, thanks to the The Inflation Reduction Act.

Registration for the program is free and available online. The City of Houston assures that there is "no obligation for homeowners to purchase solar panels." Discounts and installers are determined through a competitive auction process, per the City.

"With energy prices increasing, homeowners and small businesses are looking for opportunities to save on their energy bills and increase their resilience to climate-related events," said Mayor Sylvester Turner. "Texas Solar Switch Houston provides our community with a simple and straightforward way to become better informed about solar energy and access a competitive offer from a vetted, experienced solar installation company."

Signed and passed into law by the Biden Administration in August, the Inflation Reduction Act will invest some $369 billion in domestic energy production and manufacturing with a goal of reducing carbon emissions by 40 percent by 2030. That federal mandate means locals can now take steps towards power backup, while potentially easing up on the beleaguered Texas grid.

“More and more Houstonians are looking to solar and battery storage for self-sufficiency, which has the added benefit of making our grid more resilient,” said Hanna Mitchell, Texas program director for Solar United Neighbors, in a statement. “With the recent passage of the IRA, now is a particularly good time to go solar.”

Houston researchers develop energy-efficient film for AI chips

AI research

A team of researchers at the University of Houston has developed an innovative thin-film material that they believe will make AI devices faster and more energy efficient.

AI data centers consume massive amounts of electricity and use large cooling systems to operate, adding a strain on overall energy consumption.

“AI has made our energy needs explode,” Alamgir Karim, Dow Chair and Welch Foundation Professor at the William A. Brookshire Department of Chemical and Biomolecular Engineering at UH, explained in a news release. “Many AI data centers employ vast cooling systems that consume large amounts of electricity to keep the thousands of servers with integrated circuit chips running optimally at low temperatures to maintain high data processing speed, have shorter response time and extend chip lifetime.”

In a report recently published in ACS Nano, Karim and a team of researchers introduced a specialized two-dimensional thin film dielectric, or electric insulator. The film, which does not store electricity, could be used to replace traditional, heat-generating components in integrated circuit chips, which are essential hardware powering AI.

The thinner film material aims to reduce the significant energy cost and heat produced by the high-performance computing necessary for AI.

Karim and his former doctoral student, Maninderjeet Singh, used Nobel prize-winning organic framework materials to develop the film. Singh, now a postdoctoral researcher at Columbia University, developed the materials during his doctoral training at UH, along with Devin Shaffer, a UH professor of civil engineering, and doctoral student Erin Schroeder.

Their study shows that dielectrics with high permittivity (high-k) store more electrical energy and dissipate more energy as heat than those with low-k materials. Karim focused on low-k materials made from light elements, like carbon, that would allow chips to run cooler and faster.

The team then created new materials with carbon and other light elements, forming covalently bonded sheetlike films with highly porous crystalline structures using a process known as synthetic interfacial polymerization. Then they studied their electronic properties and applications in devices.

According to the report, the film was suitable for high-voltage, high-power devices while maintaining thermal stability at elevated operating temperatures.

“These next-generation materials are expected to boost the performance of AI and conventional electronics devices significantly,” Singh added in the release.

Energy expert: What 2025 revealed about the evolution of Texas power

guest column

2025 marked a pivotal year for Texas’ energy ecosystem. Rising demand, accelerating renewable integration, tightening reserve margins and growing industrial load reshaped the way policymakers, utilities and the broader market think about reliability.

This wasn’t just another year of operational challenges; it was a clear signal that the state is entering an era where growth and innovation must move together in unison if Texas is going to keep pace.

What happened in 2025 is already influencing the decisions utilities, regulators and large energy consumers will make in 2026 and beyond. If Texas is going to remain the nation’s proving ground for large-scale energy innovation, this year made one thing clear: we need every tool working together and working smarter.

What changed: Grid, policy & the growth of renewables

This year, ERCOT recorded one of the steepest demand increases in its history. From January through September 2025, electricity consumption reached 372 terawatt-hours (TWh), a 5 percent increase over the previous year and a 23 percent jump since 2021. That growth officially positions ERCOT as the fastest-expanding large grid in the country.

To meet this rising load, Texas leaned heavily on clean energy. Solar, wind and battery storage served approximately 36 percent of ERCOT’s electricity needs over the first nine months of the year, a milestone that showcased how quickly Texas has diversified its generation mix. Utility-scale solar surged to 45 TWh, up 50 percent year-over-year, while wind generation reached 87 TWh, a 36 percent increase since 2021.

Battery storage also proved its value. What was once niche is now essential: storage helped shift mid-day excess solar to evening peaks, especially during a historic week in early spring when Texas hit new highs for simultaneous wind, solar and battery output.

Still, natural gas remained the backbone of reliability. Dispatchable thermal resources supplied more than 50 percent of ERCOT’s power 92 percent of the time in Q3 2025. That dual structure of fast-growing renewables backed by firm gas generation is now the defining characteristic of Texas’s energy identity.

But growth cuts both ways. Intermittent generation is up, yet demand is rising faster. Storage is scaling, but not quite at the rate required to fill the evening reliability gap. And while new clean-energy projects are coming online rapidly, the reality of rising population, data center growth, electrification and heavy industrial expansion continues to outpace the additions.

A recent forecast from the Texas Legislative Study Group projects demand could climb another 14 percent by mid-2026, tightening reserve margins unless meaningful additions in capacity, or smarter systemwide usage, arrive soon.

What 2025 meant for the energy ecosystem

The challenges of 2025 pushed Texas to rethink reliability as a shared responsibility between grid operators, generation companies, large load customers, policymakers and consumers. The year underscored several realities:

1. The grid is becoming increasingly weather-dependent. Solar thrives in summer; wind dominates in spring and winter. But extreme heat waves and cold snaps also push demand to unprecedented levels. Reliability now hinges on planning for volatility, not just averages.

2. Infrastructure is straining under rapid load growth. The grid handled multiple stress events in 2025, but it required decisive coordination and emerging technologies, such as storage methods, to do so.

3. Innovation is no longer optional. Advanced forecasting, grid-scale batteries, demand flexibility tools, and hybrid renewable-gas portfolios are now essential components of grid stability.

4. Data centers and industrial electrification are changing the game. Large flexible loads present both a challenge and an opportunity. With proper coordination, they can help stabilize the grid. Without it, they can exacerbate conditions of scarcity.

Texas can meet these challenges, but only with intentional leadership and strong public-private collaboration.

The system-level wins of 2025

Despite volatility, 2025 showcased meaningful progress:

Renewables proved their reliability role. Hitting 36 percent of ERCOT’s generation mix for three consecutive quarters demonstrates that wind, solar and batteries are no longer supplemental — they’re foundational.

Storage emerged as a real asset for reliability. Battery deployments doubled their discharge records in early 2025, showing the potential of short-duration storage during peak periods.

The dual model works when balanced wisely. Natural gas continues to provide firm reliability during low-renewable hours. When paired with renewable growth, Texas gains resilience without sacrificing affordability.

Energy literacy increased across the ecosystem. Communities, utilities and even industrial facilities are paying closer attention to how loads, pricing signals, weather and grid conditions interact—a necessary cultural shift in a fast-changing market.

Where Texas goes in 2026

Texas heads into 2026 with several unmistakable trends shaping the road ahead. Rate adjustments will continue as utilities like CenterPoint request cost recovery to strengthen infrastructure, modernize outdated equipment and add the capacity needed to handle record-breaking growth in load.

At the same time, weather-driven demand is expected to stay unpredictable. While summer peaks will almost certainly set new records, winter is quickly becoming the bigger wild card, especially as natural gas prices and heating demand increasingly drive both reliability planning and consumer stress.

Alongside these pressures, distributed energy is set for real expansion. Rooftop solar, community battery systems and hybrid generation-storage setups are no longer niche upgrades; they’re quickly becoming meaningful grid assets that help support reliability at scale.

And underlying all of this is a cultural shift toward energy literacy. The utilities, regulators, businesses, and institutions that understand load flexibility, pricing signals and efficiency strategies will be the ones best positioned to manage costs and strengthen the grid. In a market that’s evolving this fast, knowing how we use energy matters just as much as knowing how much.

The big picture: 2025 as a blueprint for a resilient future

If 2025 showed us anything, it’s that Texas can scale innovation at a pace few states can match. We saw record renewable output, historic storage milestones and strong thermal performance during strain events. The Texas grid endured significant stress but maintained operational integrity.

But it also showed that reliability isn’t a static achievement; it’s a moving target. As population growth, AI and industrial electrification and weather extremes intensify, Texas must evolve from a reactive posture to a proactive one.

The encouraging part is that Texas has the tools, the talent and the market structure to build one of the most resilient and future-ready power ecosystems in the world. The test ahead isn’t whether we can generate enough power; it’s whether we can coordinate systems, technologies and market behavior fast enough to meet the moment.

And in 2026, that coordination is precisely where the opportunity lies.
