1. Environmentally Friendly

Geothermal energy is more environmentally friendly than conventional fuel sources such as coal and other fossil fuels.

2. Renewable

Geothermal energy is a source of renewable energy that will last until the Earth is destroyed by the sun in around 5 billion years.

3. Huge Potential

Worldwide energy consumption is currently around 15 terawatts, which is far from the total potential energy available from geothermal sources.

EDUARD
4. Sustainable / Stable

Geothermal provides a reliable source of energy as compared to other renewable resources such as wind and solar power.

5. Heating and Cooling

Effective use of geothermal for electricity generation requires water temperatures of over 150°C to drive turbines.

6. Reliable

Energy generated from this resource is easy to calculate since it does not fluctuate in the same way as other energy sources, such as solar and wind.

ALEX
7. No Fuel Required

Since geothermal energy is a naturally occurring resource there is no fuel required, such as with fossil fuels that are a finite resource which needs mining or otherwise extracting from the earth.

8. Rapid Evolution

There is a great deal of exploration into geothermal energy at the moment, meaning that new technologies are being created to improve the energy process.

Geothermal (meaning geo-earth, thermal-heat) is the general name given to the heat accumulated in various depths of the earth's crust. Geothermal fluid, on the other hand, is hot water, steam and gases containing many different elements and other substances. Geothermal energy is the name of the energy created by the enthalpy and heat of these fluids. This energy creates a renewable energy source by converting it to other different types of energy or by making use of direct heat energy. Geothermal energy is a new, renewable, sustainable, inexhaustible, reliable, environmentally friendly, domestic and green primary energy source. Hot dry rocks without water are also sources of geothermal energy.

Geothermal power plants have low emission levels
Geothermal power plants do not burn fuel to generate electricity, but they may release small amounts of sulfur dioxide and carbon dioxide. Geothermal power plants emit 97% less acid rain-causing sulfur compounds and about 99% less carbon dioxide than fossil fuel power plants of similar size. Geothermal power plants use scrubbers to remove the hydrogen sulfide naturally found in geothermal reservoirs.
