Answer 1

The underground water due to the hot rocks present inside the Earth turns to steam at high pressure which can turn the turbines of generators to produce electricity.
Geothermal energy is heat within the earth.
The word geothermal comes from the Greek words geo (earth) and therme (heat).
Geothermal energy is a renewable energy source because heat is continuously produced inside the earth.
The slow decay of radioactive particles in the earth's core, a process that happens in all rocks, produces geothermal energy.
These underground reservoirs of steam and hot water can be tapped to generate electricity or to heat and cool buildings directly.
To produce geothermal-generated electricity, wells, sometimes a mile (1.6 kilometers) deep or more, are drilled into underground reservoirs.
The steam and very hot water is tapped that drive turbines linked to electricity generators.
The first geothermally generated electricity was produced in Larderello, Italy, in 1904.
