Geothermal Energy Facts
Geothermal energy is a renewable energy source that derives from the heat of the earth's core. See below for our list of geothermal energy facts surrounding what this energy source is, how we can use it and the history of it.
- Geothermal energy has been around since the earth formed and humans have used hot springs heated by geothermal activity for thousands of years.
- The process of extracting geothermal energy has been in existence for over a hundred years.
- Electricity from this energy source was first generated in 1903 in Italy.
- Geothermal power is seen as clean, efficient and cost-effective yet can only be produced in particular areas.
- There are over 40 geothermal power plants in the USA alone with many more dotted across the globe.
- Iceland has the world's most efficient geothermal power stations and contributes a large percentage of global geothermal electricity production levels.
- The term "Geothermal" derives from the Greek words "geo" (meaning earth" and "therme" (meaning heat).
- The placement of geothermal power stations is very difficult as they have to be placed in an area of high geological activity to be highly efficient.
- Geothermal energy is greater along fault lines in the earth's crust and volcanic regions as liquid rock (magma) can be found closer to the earth's surface, thus providing more geothermal heat.
- Geothermal energy can also be used to provide heating for homes. This technique makes use of ground source heat instead of the geothermal energy described above.
An Overview of the Geothermal Energy Facts
Overall, geothermal activity is seen as a highly efficient, renewable and environmentally friendly source of energy. We can use this energy to provide electricity via the use of geothermal power stations or to heat our homes via the use of ground source heat pumps. Geothermal energy has been around since the earth formed and man has been known to use this for bathing purposes for thousands of years.
