Geothermal applications are cost effective, reliable, sustainable, and environmentally friendly.  These applications gather thermal energy generated and stored deep within the earth to provide heat, hot water, and electricity. Ranging in size, variety, and depth, there are a variety of geothermal applications. For example, direct geothermal applications can drill wells over 3000 feet deep and ground-source heat pumps, which are smaller applications similar to an irrigation system, are located about six feet below the ground.
