Review on Current Global Geothermal Energy Potentials and the Future Prospects

Abstract

This paper examined the current Global Geothermal Energy Potentials and their future Prospects. The study assessed the global
geothermal energy resources, their nature, extent of availability, estimated derivable electricity, current level of exploitation, and
business opportunities available. The paper presented a historical perspective of geothermal extraction for power generation,
industrial process heating and cooling of buildings. In the review, different techniques for converting geothermal energy into
electrical power had been studied. The paper also reported a summary of the global geothermal energy usage.
