Texas Is Heating Up: Why the Lone Star State Is the Next Geothermal Giant
Somewhere outside Pecos, where the desert hums quietly and the horizon barely blinks, a crew drills deep into the earth.
But it’s not oil they’re after this time, but heat — steady, renewable heat that could power homes, charge electric vehicles, and keep Texas running cleanly long after fossil fuels fade. For a state known as the heartbeat of America’s oil and gas industry, that shift might sound surprising. Yet Texas is quickly becoming a hotspot for one of the planet’s oldest—and most dependable—energy sources: geothermal.
Renewable Energy in Texas
Texas is a national leader in renewable energy thanks to massive growth in both wind and solar power – producing more wind-generated electricity than any other U.S. state, accounting for roughly 28 % of the nation’s total wind power output in 2024. Wind capacity in Texas alone far outpaces other states, making it the top source of renewable electricity in the state. U.S. Energy Information Administration+1
Solar energy is also expanding rapidly. Texas ranks second in the country for solar capacity, trailing only California, and continues to add significant new utility-scale solar projects each year. Solar generation now contributes a growing share of the state’s electric mix, playing a key role during peak demand periods and helping reduce reliance on fossil fuels.
Combined, wind and solar are increasingly meeting a large portion of Texas’s electricity demand—at times supplying around 36 – 40 % of the power on the Electric Reliability Council of Texas (ERCOT) grid, which serves about 90 % of the state according to the EIA.
This renewable leadership is driven by Texas’s vast land resources, favorable wind conditions, competitive market structures, and ongoing investment in grid infrastructure, storage, and new generation projects.
Geothermal Energy in Texas
Texas which having long been synonymous with oil drilling – has the knowledge, expertise, equipment and vast swaths of land which make it perfect for wind and solar too. However more recently the fracking revolution has introduced new technologies – specifically horizontal drilling techniques – significantly improves the return on investment and probability of a successful project – and therefore feasible.
Traditional geothermal power relies on natural hot water or steam reservoirs, which are geographically limited. Enhanced Geothermal Systems (EGS), by contrast, aims to access the Earth’s vast heat by artificially creating permeability in hot but low-permeability rock deep underground.
That’s where fracking expertise comes in: hydraulic fracturing techniques are used to create extensive fracture networks that allow water to circulate, absorb heat, and then return to the surface to produce electricity. (The Department of Energy’s Energy.gov)
The drilling methods, pressure-management know-how, and fracture modeling developed during decades of shale oil and gas fracking are directly transferable to geothermal. Horizontal drilling and multistage fracturing — proven in shale plays — now speed up geothermal reservoir creation and improve heat extraction. (NREL)
Geothermal Resource Potential in Texas
Texas sits on a geological jackpot given that beneath its surface lie vast layers of sediment and heat-trapping rock formations perfect for geothermal development. The same formations that once fueled oil booms now hold promise for thermal energy extraction with regions along the Gulf Coast, West Texas, and the Permian Basin show particularly high potential, where underground temperatures soar to levels ideal for electricity generation.
Researchers from the University of Texas at Austin have mapped geothermal “sweet spots” across the state, identifying hundreds of potential sites. Compared to wind and solar, geothermal’s advantage lies in consistency—it doesn’t flicker with sunlight or calm winds. Early studies estimate that Texas could one day generate several gigawatts of geothermal electricity, enough to power millions of homes year-round.
Benefits of Geothermal Energy
Geothermal energy brings a unique blend of environmental and economic value. Unlike fossil fuels, it releases little to no carbon dioxide once operational, and it uses remarkably little land compared to wind or solar farms. For Texas communities, this can mean cleaner air and more stable local climates.
Challenges and Barriers to Geothermal Development in Texas
Still, the path isn’t all smooth strata. Drilling deep enough to reach high heat is technically demanding and costly, especially for exploratory wells. Financing can be tricky too; investors often see geothermal as riskier than more established renewables.
On the policy side, geothermal regulations lag behind those for oil, gas, and wind. Ownership of underground heat — whether it belongs to surface landowners or mineral rights holders — can be legally murky. Public awareness is also low.
While most Texans can spot a wind farm from the highway, geothermal wells stay hidden underground, making it harder to inspire public enthusiasm. Tackling these barriers will require a mix of new policies, incentives, and storytelling that makes geothermal’s quiet power more visible.
Current Geothermal Projects and Innovations
Several pioneering ventures are already proving what’s possible. Companies like Fervo Energy and Sage Geosystems are testing advanced drilling methods borrowed from the oil industry, such as horizontal drilling and closed-loop systems that extract heat without bringing fluids to the surface. These technological tweaks could dramatically further cut costs and scale up production.
In West Texas, pilot projects are exploring “enhanced” geothermal systems — where water is injected into hot dry rock to generate steam — while universities are collaborating with private firms to refine mapping and monitoring tools. Each project adds a piece to the puzzle, turning theory into practical, replicable models for clean energy development across the state.
Policy and Regulatory Landscape
Texas’s energy regulators are beginning to take notice. The Railroad Commission of Texas, long the overseer of oil and gas operations, has started developing guidelines to accommodate geothermal projects. On the federal side, the Department of Energy is funding geothermal demonstrations and offering grants for research and risk reduction. Tax incentives for renewable energy development are increasingly extending to geothermal, helping developers offset high upfront costs.
Future Prospects and Opportunities for Geothermal in Texas
Looking ahead, geothermal’s potential in Texas could redefine the state’s energy story. Advances in drilling technology, real-time data analytics, and predictive modeling are pushing the limits of what’s possible underground. Some researchers even envision co-locating geothermal with carbon storage or hydrogen production, creating integrated clean energy hubs.
The next frontier may also include partnerships with other states and countries sharing similar geology. If Texas can prove that geothermal works at scale, it could export not just energy, but expertise — a new kind of resource boom based on knowledge and sustainability rather than extraction alone.
Conclusion
Geothermal might not have the visual drama of spinning turbines or glittering solar panels, but its potential is immense — quiet, constant, and right beneath our feet. For Texas, embracing geothermal isn’t about abandoning its energy past; it’s about evolving it. With innovation, policy support, and community investment, the Lone Star State could turn its underground heat into a cornerstone of clean, reliable energy for generations to come.
FAQs: Texas as a Geothermal Energy Hotspot
1. Why is Texas considered a hotbed for geothermal energy?
Texas has ideal underground conditions, including deep sedimentary basins, high subsurface temperatures, and extensive drilling infrastructure from the oil and gas industry. These factors make geothermal energy more accessible and cost-effective than in many other regions.
2. Does Texas have enough heat underground for geothermal power?
Yes. While Texas lacks volcanic activity, it has significant deep-earth heat that can be tapped using advanced technologies like Enhanced Geothermal Systems (EGS) and closed-loop geothermal systems.
3. How does existing oil and gas infrastructure help geothermal development in Texas?
Texas already has thousands of deep wells, skilled workers, and drilling technology that can be repurposed for geothermal projects, reducing costs and speeding up deployment.
4. What types of geothermal projects are being developed in Texas?
Texas is seeing growth in enhanced geothermal systems, repurposed oil and gas wells for heat extraction, and geothermal energy for direct use such as industrial heating and district cooling.
