Texas appears in the middle of the pack in a new ranking of the best states for sustainable development.

SmileHub, a nonprofit that rates charities, examined 20 key metrics to create its list of the best states for sustainable development. Among the metrics it studied were the share of urban tree cover, green buildings per capita and clean energy jobs per capita. Once SmileHub crunched all the numbers, it put Texas in 24th place — one notch above average.

The United Nations defines sustainable development as “meeting present needs without compromising the chances of future generations to meet their needs.”

Here’s how Texas fared in several of SmileHub’s ranking categories:

  • No. 2 for water efficiency and sustainability
  • No. 7 for presence of wastewater reuse initiatives
  • No. 18 for environmental protection charities per capita
  • No. 25 for green buildings per capita
  • No. 34 for clean energy jobs per capita
  • No. 34 for industrial toxins per square mile
  • No. 38 for share of tree cover in urban areas

California leads the SmileHub list, followed by Vermont, Massachusetts, Oregon and Maryland.

When it comes to water, a 2024 report commissioned by Texas 2036, a nonpartisan think tank, recommends that Texas invest $154 billion over the next 50 years in new water supply and infrastructure to support sustainable growth, according to the Greater Houston Partnership.

“The report underscores a stark reality: a comprehensive, sustainable funding strategy for water is necessary to keep Texas economically resilient and competitive,” the partnership says.

Report: College enrollment in petroleum programs — including in Texas — sees historic drop

looking forward

Student enrollment in petroleum engineering programs at universities — including Texas schools — has dropped significantly, according to a recent report.

This prospective energy workforce is concerned about job security as the industry moves forward in the energy transition, reports the Wall Street Journal. The number of students enrolled in petroleum engineering programs has decreased to its lowest point in a decade, the WSJ found, breaking the typical cycle, which "ebbed and flowed" alongside the price of oil.

This decline is estimated as a 75 percent drop in enrollment since 2014, Lloyd Heinze, a Texas Tech University professor, tells the WSJ. The article specifies that the University of Texas at Austin has seen a 42 percent decline since its peak enrollment in 2015, and Texas A&M University has dropped 63.3 percent. Both schools' petroleum engineering programs are ranked No. 1 and No. 2, respectively, by U.S. News and World Report. Texas Tech, which ties with the University of Houston at No. 9 on the U.S. News report, has seen a 88.1 percent decline since its peak in 2015. UH data wasn't included in the article.

The article highlights declines at Colorado School of Mines (87.7 percent), Louisiana State University (89 percent), and University of Oklahoma (90 percent) since their peak enrollment in 2015.

A decline in future workforce for the energy industry would directly affect Houston's economy. According to the 2023 Houston Facts report from the Greater Houston Partnership, Houston held 23.8 percent of the nation’s jobs in oil and gas extraction (33,400 of 140,200) 17.0 percent of jobs in oil field services (33,600 of 198,100), and 9.6 percent of jobs in manufacturing of agricultural, construction and mining equipment (20,400 of 212,000), based on data from the U.S. Bureau of Labor Statistics.

Barbara Burger tells the WSJ that new climatetech-focused startups have emerged and become more attractive to both college graduates and current oil and gas workforce. “There’s competition in a way that probably wasn’t there 15 years ago,” she shares.

The lack of college student pipeline paired with the diminishing workforce from emerging companies poses a challenge to incubant energy corporations, many of which have invested in programs at schools to better attract college graduates. The WSJ article points to BP's $4 million fellowship program with U.S. universities announced in February.

Just this week, Baker Hughes granted $100,000 to the University of Houston's Energy Transition Institute, which was founded last year with backing from Shell. In a recent interview with EnergyCapital, Joseph Powell, founding director of UH Energy Transition Institute, explains how the institute was founded to better engage with college students and bring them into the transitioning industry.

"It takes a lot of energy to process chemicals, plastics, and materials in a circular manner," he says. "Developing that workforce of the future means we need the students who want to engage in these efforts and making sure that those opportunities are available across the board to people of all different economic backgrounds in terms of participating in what is going to be just a tremendous growth engine for the future in terms of jobs and opportunities."

Clean energy jobs are already in Texas, and are ripe for the taking, according to a recent SmartAsset report that found that 2.23 percent of workers in the Houston area hold down jobs classified as “green.” While oil and gas positions are still paying top dollar, these clean energy jobs reportedly pay an average of 21 percent more than other jobs.

Report: Houston's energy transition economy sees momentum, including $6.1B in financing in 2022

Houston facts

In Houston, the energy transition movement is in full effect — at least, according to the facts and figures from a recently released report.

The Greater Houston Partnership released its 2023 Houston Facts report, which analyzes the business community across sectors. The report highlights the fact that last year Houston's energy transition brought in $6.1 billion in financing from private market investments, which represents a 61.9 percent increase compared to 2021.

"Over the last five years, Houston has seen constant growth in annual energy transition investments, with a notable surge observed from 2020 onwards," reads the report.

Corporate and strategic merger and acquisition investments are what dominated the five deal types, according to the report, representing 68.8 percent of the total investment in 2022. Additionally, private equity accounted for 19.3 percent of all deals, with venture capital comprising 9.5 percent.

According to Houston Facts, there are 550 Houston-based energy transition companies working in battery/energy storage, biofuels, carbon capture, use, and storage, circular economy, and other energy value chains.

The report also looked at clean energy job growth, which increased from 66,047 professionals in the Houston metro area in 2021 to projected increase to 71,305 jobs in 2022. The fastest growing type of clean energy job is within energy efficiency, a section that accounts for 68.1 percent of total clean energy employment last year, which increased 28.2 percent from 2021. Additionally, clean vehicle employment also saw a 14.7 percent increase while job counts in grid and storage and clean fuel applications declined notably in 2022, per the report.

Compared nationally, personal finance website SmartAsset recently ranked the Houston metro area as the fifth best place in the U.S. for green jobs, which pay an average of 21 percent more than other jobs. The SmartAsset study found that 2.23 percent of workers in the Houston area hold down jobs classified as “green.”

The report also analyzed Houston's progress when it comes to emissions. Here are some of the Houston Facts on emission data from the U.S. Environment Protection Agency and the Greenhouse Gas Reporting Program:

  • Houston's power plant sector was as the largest greenhouse gas emitter with 43.2 percent of the region's total industrial emissions, and the sector has had an overall increasing trend over the past few years.
  • With 27.5 percent of industrial emissions, the chemicals sector came in No. 2, but the sector peaked in 2018, slightly declined in 2019, and have remained relatively constant through 2021.
  • Refineries ranked third, with for 21.2 percent of emissions, and have remained stable without notable increase over the past few years.
  • Petroleum and natural gas sector emissions have consistently increased since 2012, except for 2017. That year, Houston's overall emission rate reached its lowest point in the past decade at 225.1 mtCO2e.
  • Currently, Houston's emission rate is slightly below the highest point of the past ten years, which was 243.2 mtCO2e recorded in 2012.

Houston cleantech company closes $12M seed round

fresh funding

Houston-based Helix Earth Technologies has closed a $12 million Seed 2 funding round to scale manufacturing of its energy-efficient commercial HVAC add-on technology.

Veriten, a Houston-based energy investment firm, led the round. Rua Ventures, Carnrite Ventures, Skywriter LLC and Textbook Ventures also participated.

Helix Earth—which was founded based on NASA technology, spun out of Rice University and has been incubated at Greentown Labs—is developing high-efficiency retrofit dehumidification systems that aim to reduce the energy consumption of commercial HVAC units. The company reports that its technology can lead to "healthier indoor air, lower energy bills, reduced building maintenance, and more comfortable spaces for building owners and occupants."

"Building owners are dealing with rising energy costs, uncontrolled humidity, and aging infrastructure with no viable, cost-effective path forward. We are in the field today solving these problems for commercial customers, and this capital puts us on an aggressive path to scale,” Rawand Rasheed, Helix Earth co-founder and CEO, said in a news release.

“The strength of this round reinforces our team's conviction that we can transform innovation-starved sectors with transformational solutions that deliver order-of-magnitude improvements to owners and operators, for both their bottom line and the environment,” Rasheed added.

Maynard Holt, Veriten’s founder and CEO, said that the investment firm is tripling its investment in Helix Earth.

"The team has built breakthrough technology with real applicability across multiple industries,” Holt said in the release. “Their first product will have an immediate and measurable impact on our energy system, and they are already pursuing adjacent innovations to help heavy industries operate more efficiently and with less waste. This is a well-rounded team with a proven track record of strong execution and disciplined capital management.”

Helix Earth also closed a $5.6 million seed funding round in 2024, led by Veriten.

Last year, the company secured a $1.2 million Small Business Innovation Research (SBIR) Phase II grant and won in the Smart Cities, Transportation & Sustainability contest at the 2025 SXSW Pitch Showcase. Rasheed was also named to the Forbes 30 Under 30 Energy and Green Tech list for 2025.

SLB and NVIDIA expand partnership to scale AI across energy sector

AI partnership

Houston-based energy technology company SLB has expanded its 18-year tech collaboration with chipmaker NVIDIA to include the development of an “AI factory for energy.”

Through their partnership, SLB and NVIDIA will create AI infrastructure and models built around SLB’s existing digital platforms to help energy companies scale AI for data and operations.

In addition to the development of the “AI factory,” SLB will:

  • Provide modular design services to enhance NVIDIA’s blueprint for building, launching and operating gigawatt-scale AI data centers. In this case, modular design involves manufacturing data center components off-site.
  • Use NVIDIA’s AI infrastructure to improve the processing of large datasets and AI models across SLB’s digital platforms.

Energy companies generate vast amounts of operational data, which can slow down and silo decision-making, SLB says. By combining NVIDIA’s Omniverse libraries and its Nemotron open models with SLB’s digital and AI platforms, the companies aim to more rapidly transform data into actionable insights.

Omniverse libraries are sets of prebuilt 3D elements, such as objects, surfaces and interactive features, that make it easier to construct detailed virtual spaces without having to design everything manually. They’re commonly used for building immersive environments, digital replicas of real-world systems and simulation scenarios.

Nemotron open models are AI models that are freely available to download and modify. Instead of relying on a hosted service, you can run them on your own infrastructure and tailor them to fit specific needs.

Vladimir Troy, vice president of AI infrastructure at NVIDIA, says the energy sector is at the forefront of AI driving a “new industrial revolution.”

“The winners in AI will be companies with the best data, the deepest domain expertise, and the ability to scale,” Demos Pafitis, SLB’s chief technology officer, added. “By collaborating with NVIDIA to advance modular data center construction and harness our domain expertise and digital platforms, we’re enabling the energy industry to deploy AI at scale and transform operational data into smarter decisions.”
