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.

Approximately 100 startups from around the world pitched their breakthrough technologies and businesses during Houston Energy and Climate Week, with a select few taking home top prizes and bragging rights.

Each year, investors at the Rice Alliance Energy Technology Venture Forum name the 10 most-promising startups. Greentown's Climatetech Summit also culminates in a pitch event, where member companies can earn cash prizes.

Here's who won at two of the week's anchor events and competitions.

Rice Alliance Energy Tech Venture Forum

The 23nd annual event was held Thursday, Sept. 17, at Rice University’s Jones Graduate School of Business. The most-promising companies were selected by industry experts and participating investors attending the event.

The 10 most-promising companies included:

  • Australia-based Aquafortus, which has developed a non-thermal liquid to liquid desalination technology for resource recovery from wastewater brine
  • Houston-based Focis AI, which converts industrial laser scans into a queryable digital twin of refineries and plants
  • Houston-based ironlattice, a semiconductor manufacturing company
  • Houston-based Licube, which has developed technology to produce ultra-high-purity lithium compounds for the fusion energy, pharmaceuticals, semiconductors and high-performance solid-state battery sectors
  • Houston-based Mars Materials, a clean chemical manufacturing business that is working to convert captured carbon into resources, such as carbon fiber and wastewater treatment chemicals
  • Dallas-based MCatalysis, which has developed a suite of proprietary microwave-driven catalysts to produce high-quality, ready-to-use fuels compatible with existing infrastructure
  • Oslo, Norway-based OTee, an automation machinery manufacturer
  • Houston-based Pike Robotics, which deploys its Wall-Eye robot to inspect hazardous tanks without taking assets offline
  • New Mexico-based Spiritus, a direct-air-capture (DAC) technology company
  • San Francisco-based UptimeAI Inc., which develops AI reasoning agents for industrial operations teams

Stellai won the People's Choice Award. The Norwegian company develops AI products for the waste management industry.

The energy technology ventures selected to participate in the forum were named earlier this year. See the full list here, and read about last year's winners here.

Greentown Lab's Climatetech Summit

The annual summit was held Wednesday, Sept. 16, featured a number of Houston startups in its pitch competition and lighting pitch round. Judges included Dave Dreessen,, Jon Greene, Naval Preet Singh, Philip Llewellyn, Erin Madro, Justin Yeung, Jay Kim, Rawand Rasheed and Moji Karimi.

Pitch winners included:

  • First place: Elementium Materials' CEO Matthew Dawson, winning a $10,000 cash prize sponsored by TotalEnergies plus another $10,000 in legal services sponsored by Foley Hoag. The company develops advanced battery electrolytes. It is a Greentown Boston member; though Dawson is based in Houston.
  • Second place: Houston-based Solidec CEO and co-founder Ryan DuChanois, winning $5,000 in legal services sponsored by Foley Hoag. The company electrolyzes air, water and electricity into onsite hydrogen peroxide.

Lightening pitch winners included:

  • First place: Montana-based MagDrive Technologies, winning a $1,000 cash prize sponsored by Energy Transition Ventures. The company develops magnetically actuated, zero-emission valve systems that eliminate fugitive emissions and improve reliability.
