Geothermal fields produce only about one-sixth of the carbon dioxide that a relatively clean natural-gas-fueled power plant produces. Binary plants release essentially no emissions. Unlike...
10 maj 2024 · Geothermal energy is heat that is generated within Earth. (Geo means “earth,” and thermal means “heat” in Greek.) It is a renewable resource that can be harvested for human use. About 2,900 kilometers (1,800 miles) below Earth’s crust, or surface, is the hottest part of our planet: the core.
11 paź 2024 · geothermal energy, a natural resource of heat energy from within Earth that can be captured and harnessed for cooking, bathing, space heating, electrical power generation, and other uses.

Geothermal energy is thermal energy extracted from the Earth's crust. It combines energy from the formation of the planet and from radioactive decay. Geothermal energy has been exploited as a source of heat and/or electric power for millennia.
Geothermal power plants are a source of 24/7 renewable electricity, unlike wind and solar which are variable and dependent on weather conditions.
Geothermal power plants convert steam or hot water from the Earth into electricity by using turbines connected to generators. The temperature gradient beneath the Earth's surface can reach over 25 °C per kilometer, making deep drilling feasible for extracting geothermal energy.
