Geothermal Energy Pros and Cons


Heat that is a great source of thermal energy. Geothermal energy is energy contained beneath Earth’s crust. A connection of the words ‘geo’ and ‘thermal’ simply refer to the origin of this energy, where ‘geo’ stands for earth and ‘thermal’ for heat. What is geothermal energy? Geothermal energy comes in the form of heat produced within the Earth. How is geothermal energy produced? PROS OF GEOTHERMAL ENERGY.

Geothermal Energy

Eco Friendly Daily

Geothermal energy literally means the heat from within the earth. The energy is contained in the concentrated heat that the earth’s core radiates. It is only then that the heat can be drawn and utilized as a source of energy. However, this hot water may remain underground and form geothermal reservoirs. These reservoirs can provide a powerful source of energy. In fact, in Iceland, entire districts are heated with geothermal energy.
