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.

Houston energy transition hub opens applications for new fundraising cohort

apply now

EnergyTech Cypher has opened applications for its second Liftoff fundraising program.

Applications close May 20 for the 10-week virtual fundraising sprint. The program is geared toward energy and climatech founders preparing to raise their first institutional round. It will cover fundraising requisites, like pitch materials, term sheet negotiation and round closing, according to a release from EnergyTech Cypher.

The program kicks off June 1 and runs every Monday from 1-3 p.m. CST. It will conclude with an in-person capstone simulation in Houston on August 3, where founders will work to close a mock round.

Jason Ethier, EnergyTech Cypher founder and CEO, will lead the program with Payal Patel, an EnergyTech fellow and entrepreneur in residence.

The program is available through Cephyron, EnergyTech Cypher's new investor relationship management platform, built specifically for energy and climatech founders. Users must have a Cephyron Boost membership to participate in the Liftoff program.

The Cephyron IRM app recently went live and is available to founders at any point in their fundraising process, according to the news release. The platform aggregates investor data, tracks market signals and delivers curated weekly recommendations.

EnergyTech Cypher launched Liftoff last year. The inaugural cohort included 19 startups, including Houston-based AtmoSpark Technologies, The Woodlands-based Resollant and others. Each participant closed at least one fundraising deal, according to EnergyTech Cypher.

EnergyTech Cypher rebranded from EnergyTech Nexus earlier this year. It also launched its CoPilot accelerator in 2025. The inaugural group presented its first showcase during CERAWeek last month.

EnergyTech Cypher's annual Pilotathon Pilot Pitch and Showcase applications also opened this month. Find more information here.
