Texas has room to improve when it comes to energy efficiency, recent data from WalletHub shows.

The personal finance website ranked Texas at No. 35 on the latest Most & Least Energy-Efficient States list. Texas improved by one spot on the 2025 report, after coming in at No. 36 last year.

The report measured and ranked the efficiency of auto energy and home energy consumption in the 48 U.S. mainland states based on data from the U.S. Census Bureau, National Climatic Data Center, U.S. Energy Information Administration and the U.S. Department of Transportation – Federal Highway Administration.

Texas earned an overall score of 50.60. It was ranked No. 27 for home energy efficiency and No. 41 for auto efficiency. By comparison, No. 1-ranked Vermont earned a score of 85.30, ranking No. 2 for home energy and No. 6 for out energy.

The top five overall states included:

  • No. 1 Vermont
  • No. 2 California
  • No. 3 Washington
  • No. 4 New York
  • No. 5 Massachusetts

South Dakota earned the top rank for home energy efficiency, and Massachusetts earned the top rank for energy efficiency.

“Energy efficiency doesn’t just help save the planet – it also helps save you money by lowering the amount of electricity, gas, oil or other types of energy you need to consume. While there are some steps you can take to become more energy-efficient on your own, living in the right area can give you a big boost," WalletHub analyst Chip Lupo said in the report. "For example, certain states have much better public transportation systems that minimize your need to drive, at least in big cities. Some places also have better-constructed buildings that retain heat better during the winter or stay cooler during the summer.”

According to the report, some progress is being made in increasing energy efficiency across the country. The U.S. Energy Information Administration expects 26 percent of electricity generation in 2026 will come from renewables. A number of them are being developed in the Houston area, including recent announcements like the Pleasure Island Power Collective in Port Arthur.

Still, Houston earned an abysmal ranking on WalletHub's greenest cities in the U.S. report earlier this year, coming in at No. 99 out of 100. Read more here.

Port Houston receives $25 million grant for Bayport hydrogen project

The Port of Houston Authority (Port Houston) received a $25 million grant from The Department of Transportation and the Federal Highway Administration this month to go toward a hydrogen fueling station for heavy-duty trucks in Bayport, known as Bayport HRS.

The funds will also support a public-private collaboration between the port and industrial gas company Linde Inc. with additional partners GTI Energy, Argonne National Laboratory and Center for Houston’s Future, according to a statement.

“The Houston Ship Channel is the busiest waterway in the nation,” Charlie Jenkins, Port Houston CEO, said in the news release. “As one of the channel’s leading advocates, Port Houston is committed to fostering sustainability, resilience, collaboration, and quality of life for the community and nation we serve.”

Bayport HRS will be an innovative pipeline-based hydrogen refueling station (HRS), which will be able to offer high fueling throughput and be publicly accessible. Linde will design, construct, own and operate the new facility.

“Partnering with Linde, one of the largest hydrogen producers in the world and owner of a major pipeline complex that serves the Houston region, is in line with the Port’s strategy of engaging the Houston Ship Channel industry on projects that benefit the community, promote sustainability, decarbonization, and clean transportation,” Rich Byrnes, Port Houston chief infrastructure officer, said in the news release.

Bayport HRS supports the Port’s Sustainability Action Plan and its net-zero emissions goal by 2050. The project will also align with national strategies for clean hydrogen and transportation decarbonization.

Another goal of the collaboration is to support the U.S. National Blueprint for Transportation Decarbonization, the National Zero-Emission Freight Corridor Strategy, and U.S. National Clean H2 Strategy and Roadmap.

In 2024, Port Houston secured nearly $57M in grant funding in sustainability efforts.

"The Houston/Gulf Coast's regional clean hydrogen economy continues to gain momentum, including with announcements such as this,” Brett Perlman, managing director at the Center for Houston's Future, said in the news release. "We are excited to be part of this important work to build out a clean hydrogen transportation network. This is also another great example of collaboration among business, government and community to get things done."

Here's how Houston and Texas fared on a new electric vehicle report. Photo via Getty Images

Texas ranks high on new EV study, but Houston was outpaced by other metros

driving toward progress

A new study shows that Texas is among the top of the pack for states with the most electric vehicle registrations. But Houston falls behind other large metros in the state for EV friendliness.

The March report from StorageCafe, which compiled data from the Federal Transit Administration, the Federal Highway Administration, the Department of Energy and other sources, showed that Texas had the third-most EV registrations in the county in 2021 at 112,000 vehicles.

California outpaced the rest of the country by a longshot with 878,000 registrations, claiming the number one spot. Florida had the second-most registrations at 128,000.

The report also looked at EV friendliness, which factored in EV registrations as well as the number of charging stations per household, EV exemptions, incentives and various other factors.

Houston was ranked 32nd on the friendliness list. The report found that Bayou City drivers registered 27,251 EVs in 2021. Charging stations are available in about 3.8 percent of rental buildings and there are 0.2 charging stations for every 1,000 households in the city.

Dallas claimed the top spot for the state at No. 15 with more than 29,000 EV registrations in 2021. Though Dallas has the same ratio of EV charging stations per household, there are more charging stations in rental buildings in the city.

Austin, at No. 22, also outranked Houston. Though the capital city only registered 8,730 EVs in 2021 there are much more charging stations per household (0.7 for every 1,000) and in rental buildings (5.5 percent).

San Antonio came in at No. 36, the McAllen area at No. 75, and El Paso at No. 83.

Seattle was named the friendliest place to own an EV. The drivers in the city registered more than 47,000 EVs in 2021.

Doug Ressler, a business intelligence manager at Yardi Matrix, which contributed to the report, weighed in on the findings.

“The electric car movement is gaining momentum, but it isn’t without its challenges. The high price of an EV–although brought down by incentives now – range and charging stations still pose some problems," he said in a statement. "However, with the expansion of the charging network–including in apartment buildings–and the gradual lowering of the EV price, buying and using an EV can become mainstream in the foreseeable future."

He also estimated that EVs will "dominate the car market" by 2045. By 2050, he said EVs could make up about 90 percent of the market.

Earlier this month Hertz announced that it would triple Houston's electric rental fleet, as well as add a fast-charging hub to Hobby Airport that's designed to serve ride-hail, taxi fleets and the general public.

Japanese company launches solar module manufacturing at Houston-area plant

solar plant

A local subsidiary of a Japanese solar equipment manufacturer recently began producing solar modules at a new plant in Humble.

TOYO Co. Ltd.’s TOYO Solar LLC subsidiary can produce 1 gigawatt worth of solar modules per year at a 567,140-square-foot plant it leases in Lovett Industrial’s Nexus North Logistics Park on Greens Road. TOYO Solar’s next phase will accommodate 2.5 gigawatts’ worth of solar module manufacturing. The subsidiary eventually plans to expand manufacturing capacity to 6.5 gigawatts.

For now, TOYO Solar operates only one assembly line at the Humble plant. Once TOYO Solar has five assembly lines up and running, it could employ as many as 750 manufacturing workers there, according to Connect CRE.

TOYO says the plant enlarges its U.S. footprint “to be closer to the majority of its clients, meet the demand for American-made solar panels, and contribute to the growing demand for secure, sustainable energy solutions as demands on the grid continue to rise.”

Last month, TOYO purchased the remaining 24.99 percent stake in TOYO Solar to make it a wholly owned subsidiary. TOYO entered the Houston-area market through its 2024 acquisition of a majority stake in Solar Plus Technology Texas LLC.

"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.
