What Is Geothermal Energy?
Geothermal energy refers to the sustainable, renewable energy sourced from the earth’s core. The intense pressure at the center of the planet generates thermal energy exceeding 4,000 degrees Celsius, or 7,220 degrees Fahrenheit. The heat rises toward the earth’s surface and heats the mantle. The mantle is a semi-liquid mass of molten rock, or magma. This layer is just below the earth’s crust, and the thermal energy is strong enough to emanate to the surface.
There’s another source of geothermal heating, though you’ll have to look up to spot it. Solar energy also warms the uppermost layers of the soil, creating a source of stored energy that homeowners can tap into through ground-source heat pumps.
