Geothermal works much like a fridge. A fridge is cold inside and the back is warm. Heat is drawn out and exits at the back through coils. A heat pump is like a fridge in reverse. Geothermal uses energy from the earth in different forms. Iceland uses volcanic heat to turn water into steam to drive a turbine. Other forms just use a steady state temperature. The exchange process is taking warm air threw pipes in your house and injecting it into the earth to cool your house. To warm a house it takes the warmth from the earth and expels it into the house.
Here's a video explaining it better.
-less environmental pollution
-it avoids importing energy resources
-sustainable
-saves money
- works in all weather
- creates less waste disposal
- has a long life span
-reduces utility costs by almost 70%
-it's Renewable
The ground absorbs the sun just like solar panels and it stays at a constant heat of 55 degrees.
According to this article people think geo-thermal is a great idea, they think it might get us off oil some day. Also, the great thing about it compared to other alternatives is that it runs non-stop.
Another way to save the planet.
Act now.
