Geothermal Energy Explained

Homeowners who want a cleaner and greener source of energy can now tap into geothermal energy using ground source heat pumps.  They work much like a refrigerator they can keep your home warm and supply you with hot water while reducing your costs on the energy you need to heat water.  The geothermal pump systems circulate water through underground pipes and this absorbs geothermal heat and brings this hot water into your home.  During the summer months it works the other way around bringing heat from your home and sending it underground.

We spend millions of dollars each year heating our homes in the winter and cooling them in the summer, imagine if you could reduce those costs by 50% or more.  Geothermal heat is low maintenance with your equipment all being underground.  Nor will you ever have to worry about toxic fumes in your home like carbon monoxide from your conventional heating systems breaking down.

How Does Geothermal Work?

Deep underground there is an endless supply of geothermal energy that is generated by the magma that is found there.  This is created by decaying radioactive materials.  The supply is endless because of the volatile nature of the earth’s core, and this phenomenon has been around for more than a billion years.

The huge difference in temperature between the surface of the earth and the core is referred to as the geothermal gradient.  There is a perpetual supply of thermal energy that comes from heat radiating from the center of the earth.  The earth’s core remains at a steady temperature of about 10,000 degrees Fahrenheit.  That can provide lots of geothermal energy to keep our homes warm.  Here is a closer look at geothermal energy.

Best Places to Tap into Geothermal Energy

Areas that are best to take advantage of geothermal energy are usually around young or active volcanoes.  These are called “hot spots” and they happen around the boundaries of tectonic plates and where the crust of the earth is letting heat escape.  Some of these well know hot spots can be found along the west coast including California, Alaska and Oregon.

You can still finder geothermal energy a little closer to home albeit in milder levels.  Energy that we can use to heat our homes, power the hot water tanks or other geothermic activities can be found between 10 and 200 feet below ground.  There are vast reserves of heat that you reach that is between 5-10 miles underground.

Geothermal is another renewable source of energy that is clean, yet underutilized.  We are only now starting to realize the potential of geothermic energy and how we can use it.
