I never imagined I would see Los Angeles engulfed in flames in this way in my lifetime. As someone who has devoted years to studying climate science and advocating for climate technology solutions, I'm still caught off guard by the immediacy of these disasters. A part of me wants to believe the intensifying hurricanes, floods, and wildfires are merely an unfortunate string of bad luck. Whether through misplaced optimism or a subconscious shield of denial, I hadn't fully processed that these weren't just harbingers of a distant future, but our present reality. The recent fires have shattered that denial, bringing to mind the haunting prescience of the movie Don't Look Up. Perhaps we aren't as wise as we fancy ourselves to be.

The LA fires aren't an isolated incident. They're part of a terrifying pattern: the Canadian wildfires that darkened our skies, the devastating floods in Spain and Pakistan, and the increasingly powerful hurricanes in the Gulf. A stark new reality is emerging for climate-vulnerable cities, and whether we acknowledge the underlying crisis or not, climate change is making its presence felt – not just in death and destruction, but in our wallets.

The insurance industry, with its cold actuarial logic, is already responding. Even before the recent LA fires, major insurers like State Farm and Allstate had stopped writing new home policies in California, citing unmanageable wildfire risks. In the devastated Palisades area, 70% of homes had lost their insurance coverage before disaster struck. While some homeowners may have enrolled in California's limited FAIR plan, others likely went without coverage. Now, the FAIR plan faces $5.9 billion in potential claims, far exceeding its reinsurance backup – a shortfall that promises delayed payments and costlier coverage.

The insurance crisis is reverberating across the nation, and Houston sits squarely in its path. As a city all too familiar with the destructive power of extreme weather, we're experiencing our own reckoning. The Houston Chronicle recently reported that local homeowners are paying a $3,740 annually for insurance – nearly triple the national average and 60% higher than the Texas state average. Our region isn't just listed among the most expensive areas for home insurance; it's identified as one of the most vulnerable to climate hazards.

For Houston homeowners, Hurricane Harvey taught us a harsh lesson: flood zones are merely suggestions, not guarantees. The next major hurricane won't respect the city's floodplain designations. This reality poses a sobering question: Would you risk having your largest asset – your home – uninsured when flooding becomes increasingly likely in the next decade or two?

For most Americans, home equity represents one of the largest components of household wealth, a crucial stepping stone to financial security and generational advancement. Insurance isn't just about protecting physical property; it's about preserving the foundation of middle-class economic stability. When insurance becomes unavailable or unaffordable, it threatens the very basis of financial security for millions of families.

The insurance industry's retreat from vulnerable markets – as evidenced by Progressive and Foremost Insurance's withdrawal from writing new policies in Texas – is more than a business decision. It's a market signal. These companies are essentially pricing in the reality of climate change, whether we choose to call it that or not.

What we're witnessing is the market beginning to price us out of areas where we've either built unsustainably or perhaps should never have built at all. This isn't just about insurance rates; it's about the future viability of entire communities and regional economies. The invisible hand of the market is doing what political will has failed to do: forcing us to confront the true costs of our choices in a warming world.

Insurance companies aren't the only ones sounding the alarm. Lenders and investors are quietly rewriting the rules of capital access based on climate risk. Banks are adjusting mortgage terms and raising borrowing costs in vulnerable areas, while major investment firms are factoring carbon intensity into their lending decisions. Companies with higher environmental risks have faced higher loan spreads and borrowing costs – a trend that's accelerating as climate impacts intensify. This financial reckoning is creating a new economic geography, where access to capital increasingly depends on climate resilience.

The insurance crisis is the canary in the coal mine, warning us of the systemic risks ahead. As actuaries and risk managers factor climate risks into their models, we're seeing the beginning of a profound economic shift that will ripple far beyond housing, affecting businesses, agriculture, and entire regional economies. The question isn't whether we'll adapt to this new reality, but how much it will cost us – in both financial and human terms – before we finally act.

40+ climatetech startups join Greentown, including a dozen from Houston

green team

More than 40 climatetech startups joined the Greentown Labs Houston community in the second half of 2025. Twelve hail from the Bayou City.

The companies are among a group of nearly 70 that joined the climatetech incubator, which is co-located in Houston and Boston, in Q3 and Q4.

The new companies that have joined the Houston incubator specialize in a variety of clean energy applications, from green hydrogen-producing water-splitting cycles to drones that service wind turbines.

The local startups that joined Greentown Houston include:

  • Houston-based Wise Energie, which delivers turnkey microgrids that blend vertical-axis wind, solar PV, and battery storage into a single, silent system.
  • The Woodlands-based Resollant, which is developing compact, zero-emissions hydrogen and carbon reactors to provide low-cost, scalable clean hydrogen and high-purity carbon for the energy and manufacturing sectors.
  • Houston-based ClarityCastle, which designs and manufactures modular, soundproof work pods that replace traditional drywall construction with reusable, low-waste alternatives made from recycled materials.
  • Houston-based WattSto Energy, which manufactures vanadium redox flow batteries to deliver long-duration storage for both grid-scale projects and off-grid microgrids.
  • Houston-based AMPeers, which delivers advanced, high-temperature superconductors in the U.S. at a fraction of traditional costs.
  • Houston-based Biosimo, which is developing bio-based platform chemicals, pioneering sustainable chemistry for a healthier planet and economy.

More than 100 startups joined Greentown this year, according to an end-of-year reflection shared by Greentown CEO Georgina Campbell Flatter.

Flatter joined Greentown in the top leadership role in February 2025. She succeeded former CEO and president Kevin Knobloch, who stepped down in July 2024.

"I moved back to the United States in March 2025 after six years overseas—2,000 miles, three children, and one very patient husband later. Over these months, I’ve had the chance to hear from the entrepreneurs, industry leaders, investors, and partners who make this community thrive. What I’ve experienced has left me brimming with urgent optimism for the future we’re building together," she said in the release.

According to Flatter, Greentown alumni raised more than $2 billion this year and created more than 3,000 jobs.

"Greentown startups and ecosystem leaders—from Boston, Houston, and beyond—are showing that we can move further and faster together. That we don’t have to choose between more energy or lower emissions, or between increasing sustainability and boosting profit. I call this the power of 'and,'" Flatter added. "We’re working for energy and climate, innovation and scale, legacy industry and startups, prosperity for people and planet. The 'and' is where possibility expands."

NRG makes latest partnership to grow virtual power plant

VPP partners

Houston-based NRG Energy recently announced a new long-term partnership with San Francisco-based Sunrun that aims to meet Texas’ surging energy demands and accelerate the adoption of home battery storage in Texas. The partnership also aligns with NRG’s goal of developing a 1-gigawatt virtual power plant by connecting thousands of decentralized energy sources by 2035.

Through the partnership, the companies will offer Texas residents home energy solutions that pair Sunrun’s solar-plus-storage systems with optimized rate plans and smart battery programming through Reliant, NRG’s retail electricity provider. As new customers enroll, their stored energy can be aggregated and dispatched to the ERCOT grid, according to a news release.

Additionally, Sunrun and NRG will work to create customer plans that aggregate and dispatch distributed power and provide electricity to Texas’ grid during peak periods.

“Texas is growing fast, and our electricity supply must keep pace,” Brad Bentley, executive vice president and president of NRG Consumer, said in the release. “By teaming up with Sunrun, we’re unlocking a new source of dispatchable, flexible energy while giving customers the opportunity to unlock value from their homes and contribute to a more resilient grid

Participating Reliant customers will be paid for sharing their stored solar energy through the partnership. Sunrun will be compensated for aggregating the stored capacity.

“This partnership demonstrates the scale and strength of Sunrun’s storage and solar distributed power plant assets,” Sunrun CEO Mary Powell added in the release. “We are delivering critical energy infrastructure that gives Texas families affordable, resilient power and builds a reliable, flexible power plant for the grid.”

In December, Reliant also teamed up with San Francisco tech company GoodLeap to bolster residential battery participation and accelerate the growth of NRG’s virtual power plant network in Texas.

In 2024, NRG partnered with California-based Renew Home to distribute hundreds of thousands of VPP-enabled smart thermostats by 2035 to help households manage and lower their energy costs. At the time, the company reported that its 1-gigawatt VPP would be able to provide energy to 200,000 homes during peak demand.
