The Earth’s Hidden Energy Source That Can Provide Power for Millions of Years
The Earth’s Hidden Energy Source That Can Provide Power for Millions of Years The Secret to Unlimited Clean Energy Lies Beneath Our Feet — And It Could Power the World for Millions of Years Geothermal energy is often called the “hidden power” of the Earth. It comes from the natural heat stored deep under the Earth’s surface, where molten rock and hot minerals create an almost endless source of energy. If the United States could tap into just 2 percent of the geothermal energy found beneath the Earth’s crust, it could provide over 2,000 times the total energy the country uses in one year. This incredible potential makes geothermal energy one of the most promising renewable energy sources available today. What Is Geothermal Energy? Geothermal energy is heat that comes from inside the Earth. This heat is produced mainly by the decay of radioactive materials in the Earth’s core and mantle, and it causes molten rock, or magma, to remain hot for billions of years. Unlike solar or wind pow...
