Is cheap
Is growing at a rate of 30% annually.
Main drawback is this energy is
available only in certain places

Is produced from waterAs water is denser than air , even a
small flow of water can
yield energy more than air

Geothermal energy is energy obtained by trapping the heat of the earth itself, both from kilometers deep into the Earth's crust in volcanically active locations of the globe or from shallow depths, as in geothermal heat pumps in most locations of the planet

Three types of power plants are used to generate power from geothermal energy:
It is expensive to build a power station but operating costs are low resulting in low energy costs for suitable sites. Ultimately, this energy derives from heat in the Earth's core.
