What is geothermal energy?
Geothermal energy is defined as the natural heat of the Earth. It is one of the cleanest source of energy available on earth. Geothermal energy is abundant, reliable, & nearly inexhaustible making it a sustainable power source. The
heat from deep within the earth’s core can be used to generate electricity by building geothermal power plants.
The interior of Earth contains a massive amount of thermal energy. From the Earth’s surface, the temperature increases the deeper you go.
There are places where the Earth’s heat is closer to surface. Making them accessible with modern drilling technology.
A geothermal power plant takes water from depths of 1-4 km to the surface. In the power plant, the steam will be used to turn a turbine. This turbine generates the electricity.
What makes a successful geothermal power project?
To effectively convert Earth’s heat to power, a geothermal project must have the following criteria met:
fluid
Water or steam in the subsurface
heat
This fluid acts as a carrier of the heat
Flow
Natural pathways for the fluid to move
