Geothermal Energy
Geothermal energy is derived from heat within the earth. Energy is found deep in the earth in the form of steam, naturally heated water, and rocks that touch magma deep in the earth's crust. On a small, low temperature scale, piping is run through shallow trenches in the ground and water is circulated by a pump. This process cools a building during the summer and warms it during the winter. This form of energy has no harmful emissions and is one of the most efficient systems available.
In total, 2,700 megawatts of electricity were created in 2003 through the use of geothermal processes, and there is potential for around 11,000 megawatts of generation in the nation's northwest region alone. Pennsylvania has the potential to increase its use of geothermal systems, according to the U.S. Department of Energy. Newer and redeveloped buildings can take advantage of geothermal processes using both direct heating and heat pumping systems. Since Pennsylvania is in a geologically stable area, residential and commercial spaces can benefit with geothermal systems.
