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
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.
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 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.

People have used geothermal energy since the dawn of civilization for cooking and bathing

it will last forever

using the energy does not deplete the energy source
Wind and geothermal will never run out, but they will not supply the world's demands either. It's not clear how long petroleum will last, more is still being discovered. Uranium will last until the end of this century, at least.
Geothermal energy is renewable until radioactive decay stops occurring in the Earth's mantle, which won't happen for a long time yet.
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.
