Earth's internal heat powers our homes
Geothermal energy harnesses Earth's deep heat for clean, continuous power, offering a reliable, low-emission alternative that could significantly boost global energy security.
Geothermal energy taps into the planet's immense internal heat, generated by radioactive decay, to create reliable, sustainable electricity. This process involves drilling deep wells to access hot water and steam, which then drive turbines. The first commercial geothermal power plant began operating in Larderello, Italy, in 1904. Countries like Iceland now get about 25% of their electricity from geothermal sources, contributing to nearly 100% renewable grids. This technology offers steady, around-the-clock power, unlike solar or wind, with minimal greenhouse gas emissions. Enhanced geothermal systems could one day supply up to 10% of global electricity, revolutionizing energy security.
