Geothermic Energy

This one takes advantage of the energy of the materials in fusion on Earth’s interior. So, it means that it can just be applied on volcanic areas.

In this system, the reservoirs of subterranean water at high temperatures (of about 400º C) are used to trigger the turbines (this is, the steam that comes from those waters is the responsible of making the turbines work), and then, start generating electric energy.

This kind of energy system doesn’t pollute, even though you can see an emission of a white steam, that isn’t more that water steam.
Although, the costs of construction and maintenance of these systems are very high.
