Oil Workers Find New Path in Booming Geothermal Energy

Mike Fleming spent a decade drilling wells in New England, but he never imagined his career would lead him to the forefront of clean energy. When his boss recommended him for a geothermal drilling position in late 2024, Fleming discovered something remarkable: the skills he'd honed for years transferred almost seamlessly to this sustainable energy source.

"You're making a hole in the ground, you're putting some plastic pipe down there, and you're sealing the hole," Fleming explained. The difference? Instead of extracting fossil fuels, he's tapping into the Earth's natural heat to warm and cool homes.

Fleming isn't alone in this career transition. As many as 300,000 workers already possess the skills needed for geothermal energy, according to a 2024 Department of Energy report. These drillers, geologists, and technicians spent years perfecting complex techniques in oil and gas fields, and now that expertise is opening doors in renewables.

Geothermal energy works by drilling into the Earth to access consistent temperatures underground. Conventional systems reach 200 to 500 feet down, finding rock that hovers around 50 to 60 degrees Fahrenheit. Enhanced geothermal goes much deeper, boring thousands of feet to reach temperatures as hot as 750 degrees, hot enough to power entire communities.

The timing couldn't be better. While other renewable energy sources face political headwinds, geothermal has found bipartisan support. Recent legislation preserved tax credits through 2033, and the Department of Energy just announced $171.5 million for next generation field tests.

Cindy Taff saw this potential years ago. After spending 35 years at Shell, she grew frustrated watching the oil giant overlook geothermal opportunities. In 2020, she co-founded Sage Geosystems to bridge the gap between fossil fuel expertise and clean energy needs.

"What people tend to overlook is that the oil and gas industry over the last 100 years has really done a lot of innovative stuff," Taff said. That innovation, from offshore drilling in thousands of feet of water to hydraulically fracturing rock formations, translates directly to accessing deep geothermal resources.

The industry is already growing. The domestic geothermal workforce has climbed to 8,870 people, with 145,000 workers employed globally. Drilling companies are taking notice, recognizing the long term potential as they shift resources toward renewable projects.

The Ripple Effect

This transition means more than just jobs. It represents a practical pathway for entire communities built around fossil fuel extraction to evolve without leaving workers behind. Third generation driller Brock Yordy, who started at 16, compares the skill transfer to hanging a painting on different wall types: the tools might vary slightly, but the fundamentals remain the same.

Jonathan Ajo Franklin, a geophysicist at Rice University working with geothermal startups, sees the technical overlap clearly. The same industry that spent decades learning to extract oil from stubborn rock formations now possesses exactly the expertise needed to efficiently drill for heat energy.

For workers like Fleming, it's a chance to apply hard earned skills to something that feels genuinely hopeful. "There's not many jobs where you're going to, by 500 feet, be drilling a piece of the subsurface that hasn't been touched in 25,000 to 100,000 plus years," Yordy said. "It's like being Indiana Jones."

As data centers and factories search for reliable clean power, geothermal stands ready to deliver, powered by workers who've been preparing for this moment their entire careers.
