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.

Op-Ed: To protect the Texas grid, help Texans protect themselves

guest column

On the evening of May 16, a devastating “derecho” storm howled through Houston. Nearly 800,000 customers lost power. Many were still without electricity days later, as a heat wave baked neighborhoods that couldn’t power air conditioners.

It was yet another unwelcome reminder about the precariousness of the power grid.

These outages followed repeated grid warnings, conservation calls, and near-misses last summer and the summer before, as well as the catastrophic Winter Storm Uri freeze in February 2021.

The outages also preceded the increasingly extreme weather Texas faces and staggering growth on the ERCOT grid: after growing about 1 percent a year for 20 years, the power grid covering most of Texas may need to be 78 percent bigger by 2030.

So, this latest incident is more than a sign that Houstonians must take control of their power. It also shows that more and more, the state needs you to act.

Like any other market, a power grid runs on supply and demand. The supply of Texas energy is growing, which is great. At the same time, the economy is booming, leaving Texas setting demand records almost constantly. Generators can’t always keep up, especially when power plants break down or don’t produce electricity — there’s about an 18 percent chance that Texas will face at least one grid emergency this summer.

With odds like that, it’s no wonder that more and more Texans are finding ways to live more powerfully. Many are investing in solar panels and energy storage devices like Tesla Powerwalls.

These systems let families and business owners generate electricity during the day, store it, and use it later when there’s an emergency or just when power is scarce. They protect people from high bills and blackouts; it’s no coincidence that just since last month's storm, we've seen a five-fold increase in leads, reflecting a huge growth in interest in solar power. Further, since the storm, 90 percent of new Houston-area solar customers have bought backup battery systems, compared to 50 percent in 2024 and less than 25 percent in 2023.

That pattern has repeated across the country after severe weather events.

Homeowners and business owners can also slash their bills by weatherizing houses and buildings, the way power plants did after Uri. Advanced devices that help people automatically, and voluntarily, reduce electricity use when the grid is stretched would also help.

These improvements and investments would help more than just homeowners and business owners — they’d help the entire power grid. Every kilowatt that someone doesn’t need or can generate themselves frees up power for other families and businesses across the grid. That helps Texas keep the lights on, especially if electricity demand is about to spike as dramatically as the state expects.

Texas already incentivizes conservation and generation at a large scale. For example, large users like manufacturers and crypto miners get paid by ERCOT for reducing electricity use when the grid is stretched. And just last year, the legislature passed a $10 billion program to help fund new gas power plants.

It’s past time to extend similar incentives to everyday Texans, especially when we’re increasingly called upon to help ERCOT keep the lights on.

If crypto companies get money for reducing electricity use when ERCOT asks them to, then residential and business customers deserve to get paid too. The state could help Texans invest in technologies and smart metering programs that cut bills and automatically reward people for reducing use on the hottest afternoons and coldest mornings.

More than that, the state has got to do more to reward solar customers who generate electricity and return it to the grid when demand rises. These virtual power plants will increasingly provide vital power when the state badly needs it, and consumers need to be rewarded for it. (Fortunately, the state is looking at strategies to take better advantage of virtual power plants.)

Finally, if Texas is helping big generators build gas plants, it should figure out ways to help regular Texans install solar panels and battery storage units. Such systems obviously help protect Texans from power outages, but they also fortify the ERCOT grid by reducing the demand on it.

Last month’s derecho was exactly the sort of freak occurrence that will become more common as the weather grows more extreme. The best way to protect the grid from such catastrophes is to protect individual Texas customers as well.

Report: Solar tops coal in Texas for energy generation for the first time

by the numbers

For the first time in Texas, according to a recent report, solar energy generation surpassed the output by coal.

The report — from the Institute For Energy Economics and Financial Analysis — sourced the Energy Information Administration’s hourly grid monitor for March 2024. This shift in a predominantly oil and gas dominated history of Texas energy output, was due to solar power’s 3.26 million megawatt-hours to Electric Reliability Council of Texas (ERCOT) grid, compared to coal’s 2.96 million MWh.

In addition, coal’s market share fell below 10 percent to 9 percent for the first time ever, to just over 9 percent. The increase in solar energy pushed solar’s share of ERCOT generation to more than 10 percent for the month, which was also a first.

Due to its sheer size, Texas is the No.1 state for solar capacity. According to the report from SmartAsset, the Lone Star State has the most clean energy capacity at 56,405 megawatts, but continues to trail states with similar geographic characteristics in overall clean energy prevalence.

Texas only 38 percent of the state’s electricity capacity comes from clean electricity, and it has the second-largest solar capacity, which means Texas has the most means, space, and potential to accommodate cleaner electricity. Texas as a whole, ranked No. 22 on the list for states with the most clean energy in the SmartAsset report.

In Texas, generation in March 2024 was 1.17 million MWh more year-over-year, which is a 56 percent increase. ERCOT data shows that the system currently has 22,710 megawatts (MW) of operational solar capacity according to IEEFA, and is expected to expand by almost one-third by the end of 2024 with an additional 7,168 MW of capacity added. The number just considers Texas solar projects that have set aside the financing required to get onto the ERCOT grid and that have a signed interconnection agreement.

Texas burned 50.7 million tons of coal for electricity, which was 13 percent of the U.S. total in 2023 according to the EIA grid monitor. Coal's annual share of ERCOT demand ranged from 36 percent to 40 percent from 2003 through 2014. The last year percent. In 2020, coal was under 20 percent in 2020; and was less than 15 percent in 2023 supplying just 13.9 percent of the system’s total demand.

The IEEFA notes coal’s low March production is important because in recent years it has been the moderate temperatures of April and May and steady winds that have affected the usage and the market share.

ERock scores Anthropic deal, sees order backlog soar to $1.7B

power deal

Two months after its $400 million IPO, Houston-based ERock (NYSE: EROC) has landed a power-generator deal with AI powerhouse Anthropic, owner of the Claude platform.

In its Q2 earnings report, ERock says it will provide equipment to Anthropic with a 470-megawatt capacity. ERock specializes in utility-grade, onsite microgrid power systems for data centers and other customers. The company previously did business as Enchanted Rock.

The Anthropic deal adds to ERock’s backlog of about $1.7 billion in orders—a figure representing a 1,000 percent year-over-year jump in backorders thanks in large part to the AI boom. ERock expects most of the backlog to convert to revenue by the end of 2027, said Ian Blakely, the company’s chief financial officer.

Bank of America analyst Ross Fowler says the Anthropic contract boosts confidence in ERock’s ability to secure other major deals, according to Traders Union. The Anthropic deal is ERock’s third major data center contract, with separate Anthropic deals for operations and maintenance services expected to follow, Fowler said.

CEO John Carrington says Anthropic’s order “reinforces the momentum” ERock is witnessing across its customer base.

“We are seeing a lot of interest in Texas. It seems to be the easiest place to get a site set up,” company President Corey Amthor said

In its Q2 earnings release—its first as a public company—ERock also reported:

  • Launching generator-assembly operations at its Hyperion equipment factory in Northwest Houston. The plant will expand ERock’s assembly capabilities to 1.2 gigawatts of capacity by the end of 2026.
  • Starting construction of a $473 million, 366-megawatt El Paso Electric natural-gas-powered plant to supply power for Meta Platforms’ $14 billion, 1,000-acre AI data center campus in El Paso. Meta is the parent company of the Facebook and Instagram social media companies.

“Meta gains access to an operational data center years earlier than may otherwise be possible, while El Paso Electric gains a flexible, low-cost, low-emissions grid asset that can support long-term system reliability,” Carrington said.

Telsa eyes Houston area for $10 billion solar manufacturing plant

under review

Electric vehicle and clean energy company Tesla is considering building a new $10.1 billion solar cell manufacturing facility in Fort Bend County, according to documents filed with the Texas Comptroller’s Office.

If approved, the plant, called Project Sun City, would be located on a 3,050-acre site off FM 762 and FM 1994 in Richmond, Texas. Tesla aims to finish construction in 2028, with the plant being operational by early 2029.

The plant will manufacture photovoltaic (PV) solar cells and modules that can convert sunlight into electricity. PV Magazine reports that the facility is "the largest single manufacturing investment Tesla has proposed on paper."

Advisory and consulting firm Kroll submitted the documents to the Texas Comptroller of Public Accounts and noted if an agreement regarding tax incentives isn't reached, the project will exit Texas.

Tesla has requested credits under the Jobs, Energy, Technology, and Innovation (JETI) Act. The incentive program aims to attract large, capital-intensive economic development projects by lowering the property taxes an entity must pay over 10 years if it meets requirements related to job creation and investment. For example, pharmaceutical giant Bristol Myers Squibb Co. recently announced that its forthcoming $2.3 billion Houston-area manufacturing site is a qualified project under the JETI program.

Kroll predicts that the facility would create 9,712 new full-time jobs, over 1,100 construction jobs and billions of dollars in future property tax revenue, the documents show. Additionally, it says the project will spur $1.1 billion in local business expenditures and that Texas would increase its GDP by approximately $107 billion as a result of the project activities.

Tesla opened its $200 million Megafactory in Brookshire, Texas, last year. The company is continuing its goal to deploy 100 gigawatts of solar manufacturing in the U.S before the end of 2028. According to the U.S. Energy Information Administration, 100 gigawatts is equal to about 8 percent of the country's power grid capacity.
