Report: Houston recognized in the top 5 cities for green jobs

Green jobs are generating more green — aka money — for workers in the Houston area.

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.”

“Houston is known as being an energy hub, especially for oil. So this metro area ranking fifth may surprise some people. However, the green industry is pretty big around Houston, too,” says SmartAsset.

Topping the SmartAsset list is Dallas, followed by Denver; Newark, New Jersey; Oakland, California; and Houston.

The release of the SmartAsset study preceded a new report from the U.S. Department of Energy showing Texas added slightly more than 5,100 jobs in clean energy from 2021 to 2022. That’s a gain of 3.5 percent. Last year, Texas boasted a little over 396,000 jobs in the clean energy sector, the report says.

In the energy sector as a whole, Texas added the most jobs (nearly 51,000) of any state from 2021 to 2022, followed by California (almost 21,200), and Pennsylvania (nearly 15,200), according to the DOE report.

To determine the best places for green jobs, SmartAsset crunched data for the 50 largest U.S. metro areas that included the percentage of workers holding down green jobs, the average earnings for green jobs, and the average green worker’s earnings compared with the average worker’s earnings.

The U.S. Bureau of Labor Statistics supplies two definitions for green jobs:

  • Jobs in businesses that provide goods or provide services benefiting the environment or conserving natural resources.
  • Jobs in which workers’ duties involve making their employers’ processes more environmentally friendly.

The bureau lists these as the 10 highest-paying green jobs (followed by the median annual pay in 2021):

  • Biochemist or biophysicist, $102,270
  • Materials scientist, $100,090
  • Environmental engineer, $96,820
  • Atmospheric scientist, $94,570
  • Hydrologist, $84,030
  • Geoscientist, $83,680
  • Chemist, $79,430
  • Microbiologist, $79,260
  • Environmental scientist, $76,530
  • Conversation scientist, $63,750

Even though many green jobs in the U.S. are in renewable energy, that sector remains smaller than the traditional oil and gas industry, according to a recent report from career website LinkedIn. However, the growth of U.S. job postings in renewable energy (69 percent) surpassed the growth of job postings in the oil and gas industry (57) during the first three months of 2023 compared with the same period in 2022.

Globally, the growing demand for green-job skills is “outpacing the increase in supply, raising the prospect of an imminent green skills shortage,” the LinkedIn report says.

Among the sectors seeking workers with those skills are solar and wind power. Texas tallied almost 11,800 solar energy jobs and nearly 25,500 wind energy jobs in 2021, according to a DOE report.

Some observers believe Texas is positioned to become the world’s clean energy capital — and home to thousands more green jobs — with Houston poised to lead the way.

“Industry leaders believe the [Houston] region’s relatively high concentration of engineering talent, a solid base of support services for complex, large-scale offshore and onshore drilling projects, and legacy oil and gas infrastructure can be leveraged to assist in the energy transition and decarbonization,” the Federal Reserve Bank of Dallas says in a 2022 report.

Two Rice University spinouts, Coflux Purification and DexMat, appear on a new list of the world’s 50 cleantech companies to watch.

Cleantech Group’s 2026 Cleantech 50 to Watch list recognizes early-stage companies “creating groundbreaking solutions to address some of the world’s most pressing environmental and sustainability challenges.”

Cleantech Group, a market research, consulting, and events company, selects the 50 honorees based on insights from analysts and early-stage innovators, along with public nominations.

Destroying “forever chemicals”

Coflux, founded in 2024, offers an onsite treatment system that captures and destroys manufactured “forever chemicals”—per- and polyfluoroalkyl substances—in water and wastewater. It’s a member of Greentown Houston.

Alec Ajnsztajn, CEO; Jeremy Daum, chief technology officer; and Dana Vazquez, chief commercial officer, co-founded Coflux. Ajnsztajn and Daum earned doctoral degrees from Rice, and Vazquez earned an MBA from the university.

Coflux spun out of Rice labs directed by professors Rafael Verduzco and Pulickel Ajayan.

Last year, Coflux received a $175,000 grant from the U.S. Food and Drug Administration’s National Institute of Food and Agriculture. The startup has also raised more than $500,000 in non-dilutive funding, including $80,000 awarded in 2024 by Rice’s One Small Step Grant program.

Promoting an alternative to copper

DexMat, founded in 2015, produces carbon nanotube products such as fibers, yarns, cables, and fabric. The company’s products address demand for materials that can reduce carbon emissions, according to CB Insights.

Its main product, Galvorn, is a copper alternative made of carbon nanotube fibers. CB Insights says Galvorn is engineered to be lighter and stronger than traditional conductive materials like carbon and steel. It’s used in industries such as energy, aerospace, defense, automotive, consumer electronics, and health care.

DexMat emerged from Matteo Pasquali’s Carbon Lab at Rice. Pasquali, co-founder of DexMat, co-invented the company’s technology with the late Nobel Prize-winning chemist Rick Smalley. Smalley was a professor of chemistry, physics, and astronomy at Rice.

Pasquali is a professor of chemical and biomolecular engineering, chemistry, materials science, and nanoengineering at Rice. He co-founded DexMat with Rice graduate Dmitri Tsentalovich, the company’s director of product innovation.

Earlier this year, DexMat raised $5 million in seed funding from Non Sibi Ventures, Governance Partners, Tailwind Futures, BetterWay, Capital Factory, and other investors. The company also secured $3 million in non-dilutive funding.

In 2023, DexMat raised $3 million in a pre-seed round led by Shell Ventures.
