Houston-area company leads Texas businesses on Time's most sustainable list

Spring-based IT company Hewlett Packard Enterprise leads the list of eight Texas businesses that appear in Time magazine’s and data provider Statista’s World’s Most Sustainable Companies list for 2025.

HPE landed at No. 68, earning a score of 74.36 out of 100.

Time and Statista said the ranking highlights corporate responsibility and promotes sustainable practices.

“In an era marked by significant environmental challenges and social inequalities, it is crucial to recognize and reward companies prioritizing sustainability,” according to an article on Time’s website. “By featuring these leading entities, the ranking sets a benchmark for other businesses, fostering transparency and accountability and encouraging the integration of sustainability into core corporate strategies.”

Time and Statista’s ranking process started with a list of more than 5,000 of the world’s largest, most influential companies based on factors such as revenue and public prominence. They identified the top 500 companies based on more than 20 data points.

The process weeded out non-sustainable businesses, such as those involved in producing fossil fuels, and zeroed in on:

  • External sustainability ratings
  • Availability and quality of sustainability reports
  • Performance regarding environmental and social responsibility measures

HPE is targeting net-zero status across its supply chain by 2040. Working toward that goal, the company predicts its carbon emissions will decrease by 33 percent from 2020 to 2028.

“The climate transition demands collective action across our entire value chain, and I am resolute in my commitment to ensure that HPE plays a central role in showcasing the attainability of net-zero emissions through our technologies and actions,” said Antonio Neri, HPE’s president and CEO.

Among the ways HPE is reducing carbon emissions are:

  • Shipping certain products in bigger bundles

8 Houston energy companies land on Time's top greentech list for 2025

top honor

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.

3 Houstonians named to prestigious list of climate leaders

who's who

Three Houston executives — Andrew Chang, Tim Latimer, and Cindy Taff — have been named to Time magazine’s prestigious list of the 100 Most Influential Climate Leaders in Business for 2024.

As managing director of United Airlines Ventures, Chang is striving to reduce the airline’s emissions by promoting the use of sustainable aviation fuel (SAF). Jets contribute to about two percent of global emissions, according to the International Energy Agency.

In 2023, Chang guided the launch of the Sustainable Flight Fund, which invests in climate-enhancing innovations for the airline sector. The fund aims to boost production of SAF and make it an affordable alternative fuel, Time says.

Chang tells Time that he’d like to see passage of climate legislation that would elevate the renewable energy sector.

“One of the most crucial legislative actions we could see in the next year is a focus on faster permitting processes for renewable energy projects,” Chang says. “This, coupled with speeding up the interconnection queue for renewable assets, would significantly reduce the time it takes for clean energy to come online.”

At Fervo Energy, Latimer, who’s co-founder and CEO, is leading efforts to make geothermal power “a viable alternative to fossil fuels,” says Time.

Fervo recently received government approval for a geothermal power project in Utah that the company indicates could power two million homes. In addition, Fervo has teamed up with Google to power the tech giant’s energy-gobbling data centers.

In an interview with Time, Latimer echoes Chang in expressing a need for reforms in the clean energy industry.

“Addressing climate change is going to require us to build an unprecedented amount of infrastructure so we can replace the current fossil fuel-dominated systems with cleaner solutions,” says Latimer. “Right now, many of the solutions we need are stalled out by a convoluted permitting and regulatory system that doesn’t prioritize clean infrastructure.”

Taff, CEO of geothermal energy provider Sage Geosystems, oversees her company’s work to connect what could be the world’s first geopressured geothermal storage to the electric grid, according to Time. In August, Sage announced a deal with Facebook owner Meta to produce 150 megawatts of geothermal energy for the tech company’s data centers.

Asked which climate solution, other than geothermal, deserves more attention or funding, Taff cites pumped storage hydropower.

“While lithium-ion batteries get a lot of the spotlight, pumped storage hydropower offers long-duration energy storage that can provide stability to the grid for days, not just hours,” Taff tells Time. “By storing excess energy during times of low demand and releasing it when renewables like solar and wind are not producing, it can play a critical role in balancing the intermittent nature of renewables. Investing in pumped storage hydropower infrastructure could be a game-changer in achieving a reliable, clean energy future.”

2 Houston energy transition companies recognized for creating top inventions of the year

bright ideas

Innovations from two Houston energy transition companies have been crowned among the top inventions of the year.

Time magazine’s "200 Best Inventions of 2024" identified top innovations across consumer goods, home health, robotics, sustainability, and two dozen other categories.

Fervo Energy, a provider of geothermal power, was recognized the Green Energy category for its FervoFlex system. As Time explains, the system enables horizontal drilling into hot rock under the earth’s surface and pumping in water to generate hot water and steam. The geothermal energy that’s produced can be stored and released for future use by Fervo customers.

Jack Norbeck, Fervo’s co-founder and chief technology officer, predicts that by 2050, geothermal energy will become “the backbone of the decarbonized energy system.”

In September, Fervo secured a $100 million bridge loan for the first phase of its ongoing Cape Station project in Utah, which is being touted as the world’s largest geothermal energy plant. Slated for completion in June 2026, this initial phase is expected to generate 90 megawatts of renewable energy. Ultimately, the plant is supposed to supply 400 megawatts of clean energy by 2028 for customers in California.

Time also lauded NanoTech Materials among its Manufacturing and Materials honorees for its Insulative Ceramic Particle. This powder can be added to materials like drywall or shingles to improve fire resistance and decrease heat penetration, according to Time. NanoTech’s Wildfire Shield coating for buildings contains the powder. Wildfire Shield prevents damage to materials and harm from noxious smoke.

NanoTech’s other product, Cool Roof Coat, is painted on a building to decrease HVAC use. This year, NanoTech moved into a 43,000-square-foot space in Katy, Texas, and brought on new partners that expanded the company's reach in the Middle East and Singapore.

A third Houston company was also praised byTime is BiVACOR — named to its Experimental category of the list. The full list of this year's top inventions is available online.

Houston clean energy founder scores spot on Time's list of most influential leaders

what a coincidence

What do pop star Sabrina Carpenter and Houston geothermal energy founder Tim Latimer have in common? In addition to their successful summers in their respective industries, they both also were named influential leaders on the TIME100 Next list for 2024.

For the fifth year, Time magazine released the annual list that was established to honor influential leaders "who are not waiting long in life to make an impact," reads the announcement article, continuing, "TIME100 Next has no age requirements; its aim is to recognize that influence does not have them either, nor does leadership look like it once did."

Representing Houston, Latimer was selected for his work in geothermal energy innovation. His company, Fervo Energy, has reached numerous milestones over its seven years of existence, garnering partnerships with the likes of Google and Devon Energy and raising an estimated $531 million in venture capital investment. Last month, the company announced it received a $100 million bridge loan from an affiliate of Irvington, New York-based X-Caliber Rural Capital for the first phase of its ongoing Cape Station project, which is being touted as the world’s largest geothermal energy plant.

"At a time when emission reductions are vital, energy demand has surged to a record high as a boom in AI and data centers pushes our nation’s grid to the brink," writes Tom Steyer, co–­executive chair of Galvanize Climate Solutions, which invests in Fervo Energy, in a Time article. "Leveraging multiple forms of renewable energy will be critical to meeting this demand and advancing the climate transition.

"One such solution is geothermal, which could eliminate close to 800 megatonnes of emissions annually by 2050," he continues. "Latimer uses fracking technology to supercharge the output of geothermal wells. Last year, in collaboration with Google, his startup piloted a first-of-its-kind commercial-­scale power plant, and in November, the Nevada plant (Project Red) began pumping electricity into Google data centers. Getting juice to the grid is a key milestone for energy startups—and one many never reach."

In an interview with InnovationMap for the Houston Innovators Podcast, Latimer reported that Fervo is growing and scaling at around a 100x pace. While Fervo's first project, Project Red, included three wells, Project Cape, a Southwest Utah site, will include around 100 wells with significantly reduced drilling cost and an estimated 2026 delivery. Latimer says there are a dozen other projects like Project Cape that are in the works.

"It's a huge ramp up in our drilling, construction, and powerplant programs from our pilot project, but we've already had tremendous success there," Latimer says of Project Cape. "We think our technology has a really bright future."

While Latimer looks ahead to the rapid growth of Fervo Energy, he says it's all due to the foundation he put in place for the company, which has a culture built on the motto, "Build things that last."

“You’re not going to get somewhere that really changes the world by cutting corners and taking short steps. And, if you want to move the needle on something as complicated as the global energy system that has been built up over hundreds of years with trillions of dollars of capital invested in it – you’re not going to do it overnight," he says on the show. "We’re all in this for the long haul together."

California company launches Tesla Megapack battery project in Houston area

power on

Oakland, California-based Nightpeak Energy announced earlier this month that its 150-megawatt battery storage project in Brazoria County, known as Bocanova Power, is now operating to address Houston’s peak capacity needs.

“This battery storage project will enhance grid reliability in the Alvin area while continuing to support integrating renewable energy,” Cary Perrin, president and CEO of the Northern Brazoria County Chamber of Commerce, said in a news release. “I believe we need energy storage now more than ever for its pivotal role in reducing strain on the grid while meeting fast-growing power demand in Texas and Brazoria County."

The project reached commercial operation in August, according to the release. The project utilizes Tesla's Megapack 2 XL battery storage system, and the facility operates under a long-term power purchase agreement with an undisclosed “investment-grade power purchaser.”

“Bocanova Power demonstrates the speed at which Nightpeak Energy is overcoming complex challenges to energize projects that support America's growing need for affordable, reliable, and secure energy,” Paris Hays, co-founder and CEO/CDO of Nightpeak Energy, added in the news release. “Unprecedented AI data center and manufacturing growth has only accelerated the need for these resources.”

Hays added in the release that the company has plans for more energy infrastructure projects in Texas and in the Western U.S.

Nightpeak Energy develops, owns and operates power plants that support the growing capacity needs of a decarbonized grid. It also owns and operates 240 MW of battery storage and natural gas generation facilities.

The company was founded in 2022 and backed by equity funding of up to $200 million from Dallas-based investment firm Energy Spectrum Capital.

Texas ranks low on most energy-efficient states report

by the numbers

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.
