Geothermal energy comes from the heat that exists deep down in the Earth. It is a long-lasting, clean and sustainable energy.
Geothermal energy has traditionally been used in its most basic and most accessible forms in places where it was abundant and it did not require very complicated processes of extraction. Where thermal waters or natural vents existed, people used them to cook their food, bathe themselves with hot water, and heat dwellings, greenhouses and stables. Over the course of time and technological advances, its extraction has become much more complex.
Ever since the 1970s, intense efforts to explore and research geothermal resources with the aim of using them for the production of electrical energy or for heating and hot water have begun.
Currently, the geothermal energy potential that we possess on the Earth, just beneath our feet, is equivalent to 50,000 times the energy that is obtained from all of the gas and oil resources in the world. As it is a clean energy, it would be a solution for the world as there is growing concern about both of them because of global warming and environmental pollution. At the same time, taking greater advantage of geothermal energy gives people the opportunity to obtain a more effective control of their own local energy resources and the ability to use a source of domestic energy that is stable and safe.
