What Is Geothermal Energy

The phrase "geothermal energy" 's been around since way back when. The word "geothermal" derives from the Greek words; geo (meaning earth), and therme (meaning heat). This instantly gives us the quick definition, "geothermal energy is heat from the planet earth".

A common misunderstanding of geothermal energy is based on the source of the heat. Both sources which heat our earth will be the earth's core, and sunlight.

The earth's core is predicted to be between 3000 and 4000 degrees Celsius, which heat warms the planet earth right around the land beneath our feet, decreasing in temperature completely.

The suns surface is approximately 5600 degrees Celsius. Heat from sunlight only warms the initial few meters of our earth, and this heat is lost at night time.

So where does the misconception concerning geothermal energy actually result from? Well, lots of people think that the fairly modern approach to heating water by laying pipes under around 1 meter of earth, is geothermal energy. Many scientists disagree with this particular, as geothermal energy ought to be used to spell it out heat energy dispersed by the earth's core.

The variant of geothermal energy which originates from the sun, should be referred to as a ground heat source, because of the fact that solar technology is only in a position to heat the edge of our earth's crust, prior to the sun falls and heat is lost.

Over modern times, companies who used to market "geothermal boilers" are actually switching to the usage of the word "ground source heat pumps", as a ground source heat pump uses the suns energy, not heat energy from the earth's core.

The correct procedure for geothermal energy extraction is connected with geothermal power plants. This extraction is permitted by drilling very deep holes in to the earth, to allow them to reach a considerable degree of geothermal energy to heat water and extract steam to operate a vehicle turbines.

So, there we've the basic knowledge of geothermal energy and the variant of the energy.
