Ready to Geo? National Geothermal Day is here! (VIDEO)

Everyone knows that solar and wind power are renewable energy sources. But there's another renewable resource that's often overlooked: geothermal heating and cooling.

Homeowners can use to harness the power of the sun for their homes with geothermal heating and cooling. Instead of using a solar panel to generate electricity, you can use a geothermal or ground source heat pump system to heat and cool your home.

Sponsored by Bosch Thermotechnology, National Geothermal Day, Oct. 20 2015, aims to raise awareness about environmental and economic benefits of geothermal energy and its vital role in building a clean and secure energy future.

The website features a wealth of information, activities and resources relating to geothermal along with an educational video and interactive children’s activities. New to the website is the addition of a list of available incentives and rebates provided by each state for the installation of a geothermal heat pump system. This handy resource, which is linked to the online Database for State Incentives/Rebates for Renewable Energy (DSIRE), is quick go-to tool for homeowner/buyer and contractor use.  

Also new to the website are details for Volunteerand GeoSelfie Contests with cash gift card prizes to be awarded. For full details and sign up for the contests, visit On social media, participants should use the hashtag #GeoDay2015.

Since its launch the National Geothermal Day initiative has been recognized by a number of organizations to include the International Ground Source Heat PumpAssociation (IGSHPA), the Geothermal Research Council, individual GRC chapters, among others. To date more than 2,000 individuals have registered on the website as supporters.   

Geothermal 101

Geothermal heating works because the earth absorbs about 48 percent of the sun’s energy, leaving a fairly constant underground temperature between 45 F (7 C) to 75 F (21 C). Geothermal technology uses this stable temperature to transfer heat to and from the earth, instead of using the air in the more common air-source heat pump systems.

A home geothermal system includes a geothermal or ground source heat pump and a ground loop system made up of pipes buried in the ground. A water/antifreeze solution flows through the pipes, absorbing heat from the earth in the winter and moving it to the geothermal system inside the house. Once there, the heat is condensed and transferred to the air that is circulated throughout the home, providing warmth when needed.

If you are thinking about building a new home or wish to retrofit an existing heating-cooling system in a home you are about to build or purchase, you may very well be thinking about going geothermal. You may be like many of today’s homebuyers: especially well educated purchasers who want to know about the full range of features, options and equipment they can to put into their home, to include the heating-cooling system and equipment involved.

You also probably know that heating-cooling your home is going to be your biggest utility expense, so you want a system that will deliver comfortable, well modulated indoor comfort that operates with minimal service requirements while saving on energy bills. You might even desire a system that uses renewable forms of energy, minus any carbon fuel reliance. For all the right reasons, geothermal should definitely be a system option you should consider.
