Earth energy and geothermal energy
Posted by Cecilia under: Energy.
Sometimes people are confused about the terminology earth and geothermal energy. They sound like they’re the same thing, but they aren’t.
Earth and geothermal energy are two different types of energy. What are the differences?
Earth energy comes from the air. It uses the earths temperature for heating or cooling air which is forced into the earth.
The advantages are that it requires less energy for moving the heat than for converting one energy in another. Earth energy is widely used in Canada and northern Europe and more and more in the U.S.
Geothermal energy comes from captured steam or water. Geothermal energy requires a certain earth temperature and therefore a certain local geography.
Geothermal energy is widely used in the Philippines, Italy, Iceland, Indonesia, Mexico, New Zealand, Japan and China. Other countries like Canada and Switzerland are testing geothermal sites.
Both types of energy can be applied for residential, commercial and industrial uses.
