Bill Gates talks AI, future of energy at CERAWeek address in Houston

Bill Gates, renowned co-founder of Microsoft and founder of Breakthrough Energy, took the CERAWeek stage to a standing-room-only crowd to discuss his thoughts on the future of energy.

He was joined in conversation with Daniel Yergin, author and vice chairman of S&P Global, at the luncheon on Thursday, March 21. His remarks touched on three themes within the energy transition.

Texas as a hub for energy transition

Yergin started off the conversation inquiring about Gates and his recent tour around Texas, which included visiting energy companies' plants and facilities and their local communities. Though it might surprise people, given the history of oil and gas in the state, Texas has a strong presence in the energy transition, Gates says.

“There is some irony in the fact that so many of the capabilities to embrace (the energy transition) are here in Texas, whether it's the workforce or the permitting,” he says at the event.

Gates adds that while most of the portfolio companies at Breakthrough Energy were founded on the coasts, many turn to Texas when it comes time for their first commercial pilot.

He addressed a progress report on the energy transition as a whole.

“It’s really starting to move. There’s a lot of exciting technologies, and a lot of the big companies are coming in,” he says, specifically noting energy companies' presence at COP28.

“A heroic effort is beginning — I’m very excited about it. But we shouldn’t underestimate how difficult it will be,” he says. “There’s a lot of things that have to happen for these projects to go ahead. It’s far more difficult than anything I worked on at Microsoft.”

Steel and nuclear have big potential for disruption

Gates continued this thought but highlighting that some industries are less advanced than others.

“We’re just at the beginning of many things," he adds, noting that "the steel industry today is 99 percent the traditional process."

With that, steel has a lot of potential to be disrupted, and Breakthrough Energy has two companies working to make the industry greener, but it's an industry that's going to take time to evolve.

Nuclear is another sector Gates is excited about but is developing at a slower pace. Breakthrough Energy has five portfolio companies focused on Nuclear, including TerraPower, which Gates co-founded in 2006.

Despite nearly two decades of development, Gates says TerraPower is a "fast-moving" nuclear company in comparison to other companies out there.

AI's impact is still to be determined

The topic of artificial intelligence inevitably came up, and Gates explains that the technology has come a long way. Microsoft owns a portion of OpenAI, which created ChatGPT. Gates says he expected AI to evolve and to be able to be programmed to understand information to take longer to develop.

“We have achieved a threshold — an unusual threshold because we know how we’ve caused the knowledge represented, but we don’t understand how at a semantic level how that knowledge is being represented,” Gates says.

AI's current applications are within white collar activities, Gates explains, citing writing a regulatory permit or looking at evidence in a lawsuit. He explains that current AI capabilities could continually grow or remain stagnant for a while, he isn't sure.

"The thing that’s daunting is we don’t know how quickly it will improve," he adds.

Gates didn't comment on energy specific AI applications but noted that AI has advanced far past robotics, which would target blue collar roles.

The accolades keep rolling in for Houston-based Fervo Energy, a producer of geothermal power.

Fervo lands at No. 6 on Time magazine and Statista’s new list of America’s Top GreenTech Companies of 2025. The ranking recognizes sustainability-focused companies based on factors such as impact, financial strength, and innovation.

Time notes that Fervo broke ground in 2023 in Utah on what the company claims will be the world’s largest geothermal plant. The plant is scheduled to start supplying carbon-free electricity to the grid next year and to reach its 400-megawatt capacity in three years.

“Technologies like this only make a difference if we deploy them at large-scale in a way that can reduce carbon emissions and increase the reliability of the grid,” Fervo CEO Tim Latimer told Time in 2023.

The startup was named North American Company of the Year by research and consulting firm Cleantech Group for 2025. Fervo topped the Global Cleantech 100, Cleantech Group’s annual list of the world’s most innovative and promising cleantech companies.

Last year, Fervo also made Time’s list of the 200 Best Inventions of 2024. Fervo was recognized in the green energy category for its FervoFlex geothermal power system.

Founded in 2017, Fervo is now a unicorn, meaning its valuation as a private company exceeds $1 billion. The startup’s valuation is estimated at $1.4 billion. According to PitchBook data, the company raised $634 million in the fourth quarter of 2024.

In all, eight Houston-area companies appear among the top 250 greentech companies ranked by Time and Statista. Other than Fervo, they are:

  • No. 43 Lancium Technologies, an energy storage and distribution company
  • No. 50 Solugen, a producer of sustainable chemicals.
  • No. 56 Quaise Energy, which specializes in terawatt-scale geothermal power.
  • No. 129 Plus Power, a developer, owner and operator of battery storage projects.
  • No. 218 Dream Harvest, which promotes sustainable vertical farming.
  • No. 225 Cemvita, which uses synthetic biology to convert carbon emissions into bio-based chemicals.
  • No. 226 Syzygy Plasmonics, which decarbonizes chemical production.
Vermont-based BETA Technologies claimed the No. 1 spot. The company manufactures electric aircraft.
