At least 2000 years ago the Romans used hot springs for bathing and health. The hot springs were heated by underground heat, which is the meaning of geothermal.
10,000 years ago geothermal energy served as a source of warmth and cleansing while the minerals of geothermal energy was used for a source of healing
It has been used from the beginning of time they natives called geothermal energy (~oun~waveo)
In some countries geothermal energy has been around for thousands of years and has been used for cooking and heating.
Geothermal energy will last as long as the earth lasts, so it technically won't run out. As long as the earth's core remains molten and the sun heats the surface of the earth, we'll have geothermal energy.
Millions of years. The geothermal energy is gradually recharged by the decay of radioactive isotopes.

using the energy does not deplete the energy source
Geothermal energy will last as long as the earth lasts, so it technically won't run out. As long as the earth's core remains molten and the sun heats the surface of the earth, we'll have geothermal energy.
People have used geothermal energy since the dawn of civilization for cooking and bathing
Millions of years. The geothermal energy is gradually recharged by the decay of radioactive isotopes.
it will last forever
A renewable energy source is one that is being renewed on a regular and constant basis, such as the wind, geothermal, tides, and sunlight. It takes a very long time and a lot of effort to make oil, coal and gas so they are not considered renewable sources of energy.
a long time
Geothermal energy is renewable, as the heat from the center of the earth will be available as long as we ever need it. This energy is the only renewable energy that does NOT come from the sun.
Geothermal energy is renewable until radioactive decay stops occurring in the Earth's mantle, which won't happen for a long time yet.
