Geothermal Power

 Thermal energy is energy stored in the earth's crust, like in hot springs.

We can use it to heat things using geothermal energy, mainly by pumping water deep underground, waiting for it to heat up and then pumping it back to the surface. 

To heat our homes, but in order to generate electricity we must first pump it underground then we wait for it to heat up so much to the point it becomes steam and as the steam rises it turns turbines that turn the hot steam into electrical energy via generators, but these places to gather geothermal energy is rare, but the power gathered from these sources are extremely eco friendly as the initial startup of the geothermal power plant is slight, but it doesn't produce any pollutants at all while running.
