Geothermal energy is emerging as a significant player in the renewable energy landscape of the United States, receiving notable attention even during the Trump administration. Unlike other renewable sectors that have faced regulatory challenges, geothermal power is poised for growth, with both public and private funding expected to drive development in the coming years.
According to the European Commission, geothermal energy is derived from the thermal energy stored within the Earth’s crust. This energy can be harnessed by drilling wells that connect underground fluids to the surface, enabling its use for electricity generation, district heating, or industrial processes. While countries with accessible geothermal reservoirs have utilized this resource for centuries, enhanced geothermal systems (EGS) now allow nations with less accessible reserves to tap into substantial clean energy sources.
One of the key advantages of geothermal energy is its reliability. Unlike solar and wind power, which are dependent on weather conditions, geothermal energy can provide a constant supply of power, making it an attractive option for energy production.
In May 2023, the U.S. Department of the Interior announced plans to expedite permitting procedures for geothermal projects across the nation. This initiative aligns with President Donald Trump’s broader energy agenda. Selected projects are set to benefit from streamlined approval processes, reducing wait times from potentially years to just 28 days for urgent energy or mining projects on federal lands. “Geothermal energy is a reliable energy source that can power critical infrastructure for national security and help advance energy independence,” stated Interior Secretary Doug Burgum.
In December 2023, Fervo Energy, a leading player in the geothermal sector, announced a successful raise of $462 million in its Series E funding round. This capital will accelerate the construction of the Cape Station in Utah, which is anticipated to contribute 100 megawatts (MW) to the grid by 2026 and expand to 500 MW by 2028. “Fervo is setting the pace for the next era of clean, affordable, and reliable power in the U.S.,” remarked Jeff Johnson, General Partner at B Capital, highlighting the urgent need for scalable energy solutions amid rising demand.
In New Haven, Connecticut, construction has begun on a geothermal energy network aimed at providing clean heating and cooling to key facilities, including Union Station and a new public housing project. This initiative is part of a broader goal to decarbonize municipal buildings and transportation by 2030. “You’re going to have the most efficient heating and cooling system available,” said Steven Winter, New Haven’s executive director of climate and sustainability.
Nearby, Yale University is also advancing geothermal technology with a new loop serving its science buildings. Furthermore, a recently passed energy bill is expected to enhance the development of thermal energy networks throughout the state, providing additional momentum for geothermal initiatives.
In Framingham, Massachusetts, the first utility-owned geothermal network in the United States became operational in June 2024. The Home Energy Efficiency Team (HEET) recently secured an $8.6 million grant from the U.S. Department of Energy’s Geothermal Technologies Office to expand its existing network. This project currently delivers clean heating and cooling to approximately 140 residential and commercial customers. “This award is an opportunity and a responsibility to clearly demonstrate and quantify the growth potential of geothermal network technology,” said HEET’s Executive Director Zeyneb Magavi.
The future of geothermal energy in the United States looks promising, bolstered by federal support and innovative projects across the country. As the sector expands, it is expected to play a crucial role in achieving decarbonization goals and reducing reliance on fossil fuels.
