The 2024 edition of CERAWeek by S&P Global wrapped up last Friday in Houston, and a handful of themes emerged as topical and disruptive amid the energy transition.

Here are five takeaways from the conference, according to EnergyCapital reporting.

Funding the energy transition continues to be a challenge.

The biggest obstacle to the energy transition is — and might always be — funding it. A panel at Agora on Thursday, March 21, moderated by Barbara Burger set out to discuss the role of venture capital amid the future of energy.

Daniel Goldman, managing partner at Clean Energy Ventures, said that the first plants for these new, revolutionary technologies are going to be more expensive than its subsequent plants.

"But you have to built it," Goldman says. "'First of a kind' can be very different from the end plant, because you need to manage risk. ... But those first plants are going to be quite costly, and you're going to have to recognize that as an investor."

Microsoft and Breakthrough Ventures Founder Bill Gates would address this in his talk later that day, pointing out that traditional infrastructure investors are used to knowing what a plant would cost before its built. But in clean tech, outside of solar and wind, there's too much unknown to give the estimation those investors are looking for.

"Nothing's at the maturity level that you can do that," Gates says.

The DOE's role of de-risking green tech.

The United States Department of Energy had a significant presence at CERAWeek, with Secretary of Energy Jennifer M. Granholm making two major announcements on Monday, March 18, the first day of the conference. One of the announcements was the DOE's latest Pathways to Commercial Liftoff report, which are initiatives established to provide investors with information of how specific energy technologies commercialize and what challenges they each have to overcome as they scale.

"We develop these Liftoff Reports through a combination of modeling and hundreds and hundreds of interviews with people across the whole investment lifecycle—from early-stage capital to commercial banks and institutional investors," Granholm says in her address, announcing geothermal energy as the subject of the ninth report.

Intended to "create a common fact base and a tool for ongoing dialogue with the private sector on the pathways to commercial liftoff," according to the DOE, these reports can be instrumental for enterprises in the field.

A panel at Agora on Thursday, March 21, featuring geothermal energy innovators discussed the impact of the report. Tim Latimer, CEO and founder of Houston-based Fervo Energy, says the report included details from his company's work.

To Latimer, the report showcases geothermal energy's ability to compete from a cost perspective.

"I think geothermal is already winning that cost discussion," Latimer says. "You're talking about $45 per megawatt hour unsubsidized cost for round-the-clock, 24/7 carbon-free energy. I think that's an achievable ambition the DOE set out, and I think it's an unbeatable value proposition.

Hot topic: Geothermal energy.

Geothermal energy was discussed throughout the week following Granholm's address, in part because of its expected cost efficiency, but also because it's a type of energy that should provide a smooth transition from traditional oil and gas.

John Redfern, CEO of Eavor Technologies, global geothermal technology company headquartered in Canada, says on the geothermal panel that the geothermal industry can build off existing infrastructure.

"Most of it is building blocks that we're recycling from the oil industry — resources, people, technologies," Redfern says. "So, it's more about implementing rather than inventing some new, novel product."

Latimer agrees, adding that Fervo "is fully in the deployment phase."

"The breakthrough needed to make geothermal ready for primetime have already happened," Latimer says.

AI is everywhere — especially the energy transition.

The topic of artificial intelligence was everywhere, so much that by Thursday, panelists joked about every discussion including at least one mention of the technology.

Gates was one speaker who addresses the subject, which isn't all too surprising, since Microsoft owns a portion of OpenAI, which created ChatGPT. One thing left to be known is how directly AI will affect the energy transition — and on what timeline.

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.

Big tech sees green.

And speaking of AI, big tech companies have been making moves to lower carbon footprints, and that was made clear by the activations at CERAWeek. Microsoft and Amazon each had designated houses at the conference, alongside Oxy, Chevron, Aramco, and other traditional energy players.

At Microsoft, Houston-based Amperon, which recently announced a partnership with the tech company, presented and pitched their company. The Microsoft and Amazon houses showcased each company's low-carbon technologies.

Texas falls lower on national ranking of greenest states for 2025

room to improve

Texas dropped in the rankings on WalletHub's Greenest States 2025 report.

The report, released last month, considered 28 relevant metrics—from air and water quality to the number of alternative fuel stations and green buildings per capita—to call out states doing the best (and worst) jobs of caring for the environment.

Texas came in at No. 42 out of 50, with a total score of 42.54 out of 100. Last year, the Lone Star State ranked No. 38 with a score of 50.40 based on 25 metrics.

Texas' poor ranking was driven by its last-placed ranking, coming in at No. 50, for overall environmental quality. It was tied for No. 45 for air quality and ranked No. 46 for water quality, which helped comprise the overall environmental quality score.

Other metrics fell closer toward the middle of the pack. The state ranked No. 32 for eco-friendly behaviors and No. 39 for climate-change contributions.

California also fell on the annual report. While the state claimed the top spot in 2024, it came in at No. 7 this year. Vermont, which came in second in 2024, was named the greenest state in 2025.

Hawaii, which didn't crack the top five last year, was ranked No. 2 on the 2025 report. New York, Maryland and Maine rounded out the top five this year.

West Virginia was the country's least green state again this year, followed by Louisiana, Kentucky, Alabama and Mississippi.

The report also showed that Democrat-led states ranked around No. 12 on average, whereas Republican states fell at around No. 33.

While the WalletHub report seems bleak for Texas, others have shown more positive signs for the state. Texas was ranked slightly above average in a recent ranking of the best states for sustainable development. A recently released U.S. Energy Storage Monitor shows that Texas led all states and surpassed California in the fourth quarter of 2024 by installing 1.2 gigawatts of utility-scale energy storage for solar and wind power.

Still, WalletHub also recently ranked Houston No. 98 out of 100 of the largest cities on its Greenest Cities in America report. Read more here.

Houston renewables developer and Google agree to second solar collaboration

power purchase

EnergyRe, a developer of large-scale renewable energy projects with headquarters in Houston and New York, has signed a renewable energy agreement that will allow Google to invest in and purchase renewable energy credits (RECs) from its projects under development in South Carolina.

Google will be able to pull from energyRe’s portfolio of more than 600 megawatts of new solar and solar storage projects in the state.

The agreement marks the second partnership between the companies. Last year, energyRe and Google signed a 12-year power purchase agreement in which Google would purchase renewable energy from a 435-megawatt solar project. EnergyRe would supply electricity and RECs generated from the solar project to Google to power the equivalent of more than 56,000 homes.

"Strengthening the grid by deploying more reliable and clean energy is crucial for supporting the digital infrastructure that businesses and individuals depend on," Amanda Peterson Corio, head of data center energy at Google, said in a news release. "Our collaboration with energyRe will help power our data centers and the broader economic growth of South Carolina."

EnergyRe's work includes developing high-voltage transmission, onshore and offshore wind, large-scale solar, distributed generation and storage assets in markets around the United States. Its national onshore utility-scale portfolio includes 1,520 megawatts of contracted solar assets and 398 megawatt-hours of contracted battery storage assets.

"This agreement is a milestone in energyRe's mission to develop innovative and impactful clean energy solutions for the future," Miguel Prado, CEO of energyRe, added in the news release."We're honored to partner with Google to help advance their ambitious sustainability and decarbonization objectives while delivering dependable, locally sourced clean energy to meet growing energy demands."

Google aims to achieve net-zero carbon emissions across its operations and value chain by 2030.
