Within alternative energy, wind and solar get all the media attention, all the glamour. Yet both suffer from intermittency, from the problem that their power sources wax and wane. By contrast, geothermal draws on heat from deep below the earth to provide reliable base load power 24 hours a day.
I’ve been to several homes that are heated and cooled using geothermal technology in the course of my travels for Natural Home, but I’d never actually had the opportunity to watch as the wells were being drilled.
In the United States, renewable energy is growing, but we still don't get very much of our electricity from renewable sources. How can we speed things up?
Geothermal energy is cleaner than fossil fuels and is endlessly renewable. Find out more about why we should seriously reconsider geothermal energy as a way to meet the world's energy needs.
Geothermal heating and cooling systems rely on the earth’s constant underground temperature of 45 to 75 degrees Fahrenheit to provide comfortable indoor climates. The technology works in any size or style home, in nearly any setting on earth.
Here's why a heat pump might be a good choice for your home.
