Earth’s Geothermal Potential – 4000 Times the World Needs

Geothermal energy and its collection are still a subject of avant-garde and it is used on a small scale at global level.In this article we’ll talk a little about the Earth’s geothermal energy potential. As I said in a previous post, we hear everywhere that alternative energies are not able to provide Earth’s energy needs.

A study made by MIT in 2006, tells us that the Earth’s total geothermal potential is approximately 13,000 ZJ ( zettajoule) per year, of which approximate 2000 ZJ could be used to produce electricity using geothermal plants.

This in the conditions in which the energy needs of the entire globe over a year does not exceed 0.5 ZJ. So if we get to use only 0.25% of this potential, would be no need for coal, plutonium, oil and gas to produce electricity. But in the present, only about 1% of global energy needs was covered by geothermal sources. So, we use 0.0025% of potential.

Is it all what is capable of the actual technology or there are too strong impediments on its way? What do you think?
