Geothermal Projects
Geothermal projects are becoming more and more popular as the fossil fuels which traditionally heat and cool our homes, schools and offices are becoming more scarce. Geothermal projects have been around for some time now and were implemented in a large -- usually subsidized -- way starting in the early 1980s. Now projects are underway across the globe and in the individual home, so all can benefit from the reduced cost and increased health of this technology.

Direct Use Geothermal Water and Space Heating
-
The drilling of wells to directly heat the space and water supply of a building is something that has been actively pursued since at least the early 1980s. In California, a state sitting on a significant source of geothermal potential, projects have been implemented since 1981 in schools and communities to utilize this clean energy source. The results of these projects, still in use today, is a savings of 50 to 90 percent on annual utility costs.
Geothermal Power Plants
-
Impressively, geothermal power plants can operate to generate electricity in hot and moderate temperature climates. Technology referred to as binary cycle power plants are one method of tapping into geothermal energy. Used in moderate climates, liquid is heated to evaporation to turn an electricity generating turbine. Projects to establish this technology as a clean energy source have been in action since the early 1980s in Nevada.

Global Geothermal Projects
-
Geothermal energy is being used by over 52 million people worldwide and over 70 countries are undertaking geothermal energy projects, mostly in the form of geothermal power plants. There has been a 50 percent increase in countries pursuing geothermal projects since 2007. The largest increases in geothermal energy projects have occurred in Europe, with 10 new countries taking on projects, while in Africa, six countries are undertaking geothermal projects.
Geothermal At Home
-
Do it yourself geothermal projects are becoming increasingly popular, with websites popping up to help the homeowner along the way. The idea is to tap into the ground temperature and utilize a system of fluids, pumps and electricity to heat and cool your home. In order to establish an effective system you must first calculate the energy needs of your home, have a thorough understanding of the system and the money to invest in the project.
