Houston hosted the inaugural Energy + Climate Startup Week in September, which brought together leading energy and climate venture capital investors, industry leaders and startups from around the world to showcase the most innovative companies and technologies that are transforming the energy industry while driving a sustainable, low-carbon energy future.

Repsol was one of the inaugural sponsors for the weeks kick off event that hosted several leading startups. This year marked 25 years of energy innovation for Repsol in the United States. As the energy landscape evolves, Repsol has committed to significant growth in renewable capacity, with an impressive 720 MW of solar and storage capacity already operational and 1.5 GW under construction.

Caton Fenz, CEO for Repsol’s Renewables North America shares more about Repsol’s approach to expanding its renewable footprint, integrating green energy into its core business and leveraging Houston’s unique role as a leader in the energy transition. Here’s an inside look at Repsol’s milestones and future goals in the journey toward decarbonization and a sustainable energy future.

Can you tell us more about Repsol’s strategy for expanding its renewables business?

This year Repsol is celebrating 25 years of energy development in the United States. Across the US, we have a team of more than 800 employees, with more than 130 employees working in the renewables business specifically.

Repsol’s growth ambition in the US renewable energy market is significant. Since launching our renewables activity in the US three years ago, we have installed more than 720 MW of solar generation and energy storage capacity. Today we have more than 1.5 GW of additional solar and energy storage capacity under construction, and more than 20 GW of solar, wind and energy storage in development across 13 states.

How does Repsol plan to integrate renewable energy sources into its broader business model?

Repsol Renewables operates in accordance with Repsol’s values and strategies. Renewable energy generation is one of the pillars of Repsol’s decarbonization strategy. Repsol will invest between €3 and 4 billion to organically develop its global project portfolio and aims to reach between 9,000 MW and 10,000 MW of installed capacity by 2027. Of this, 30% will be in the United States.

With these objectives in mind, we have been able to accelerate the development of wind, solar, and energy storage across the US market and the globe. By expanding our renewable energy business, we can further meet record demand growth for renewable energy.

What are the key projects or milestones that have been achieved within Repsol’s renewables portfolio so far?

Earlier this year, we announced the commercial operation of Frye Solar, our largest solar project worldwide. This project, located in Swisher County, Texas, has a total capacity of 637 MW. And as noted above, we have an additional 1.4 GW of projects under construction currently. These major energy infrastructure projects are indicative of the scale of our operations in the US.

Why does Repsol believe being located in Houston is critical for its business, particularly in the energy transition?

Repsol is proudly committed to Houston’s role in developing and delivering energy and value for the world. Houston is known as the Energy Capital of the World and over the next 10 years, we’ll see it be known as the Energy Transition Capital of the World. With Repsol’s Renewables North America business located in downtown Houston, we have access to talent and partnerships in a booming city filled with energy experts.

Why does Repsol see value in participating in Houston Energy + Climate Startup Week?

At Houston Energy + Climate Startup Week, Repsol Renewables is honored to support and learn from leaders and investors in the energy and climate industry. We believe it is important to continuously invest in talent, ideas, and collaboration across the energy value chain as we pursue our net zero by 2050 goal.

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.
