Colossal energy potential under our feet

The United States is discovering a source of geothermal energy that could transform its energy landscape. A group of experts has identified a capacity of 4 GW of energy, called โ€œsuperhot and superdeep.โ€ This type of energy has the potential to decarbonize the country, challenging traditional reliance on more polluting energy sources. However, accessing this resource will not be easy and will require significant technological advances.

The rise of geothermal energy: a little-known reality

Although currently accounting for only 0.4 percent of U.S. electricity generation, the U.S. Department of Energy envisions geothermal energy could supply up to 10 percent of the countryโ€™s electricity by 2050. That would represent a twenty-fold increase in its current contribution. To achieve this, continued technological and policy support will be essential.

The geographical footprint of geothermal energy

California leads the way in geothermal production, with 66.6 percent of the total produced in the United States, thanks in part to the Geysers, the world's largest geothermal field. Other states such as Nevada, Utah, Hawaii, Oregon and Idaho are also major producers. New projects are being launched, boosted by $74 million in funding for seven pilot projects aimed at expanding the use of geothermal energy beyond traditional locations.

New technological advances and challenges

Deep, horizontal drilling technologies now make it possible to access geothermal resources in previously inaccessible regions. However, the lack of sufficient technological advances remains a major obstacle. Enhanced geothermal systems (EGS), for example, require advanced techniques similar to fracturing to extract heat from deep geopressurized rocks.

Environmental and economic benefits of geothermal energy

Geothermal energy offers multiple environmental benefits, including a significant reduction in CO2 emissions compared to coal-fired power plants. It also requires less water than traditional thermal power plants. Although its initial cost is high, negative externalities are significantly reduced, and it benefits from federal incentives.

Ecological perspectives and impacts

Beyond the 4 GW already identified, offshore geothermal projects could see the light of day, inspired by floating wind turbines. However, their impact on natural ecosystems could be significant, which raises questions about their classification as a clean energy source. Despite this, these initiatives remain preferable to more controversial options, such as drilling in Yellowstone, discussed several months ago but extremely risky.

Challenges and future of geothermal energy in the USA

The future of geothermal energy in the United States looks bright despite technical and ecological challenges. Its expansion could play a crucial role in America's energy transition, offering a cleaner, more sustainable alternative to traditional sources.
