Alternative Energy


NYSERDA: Geothermal Heat Pumps
Geothermal heat pump systems tap the constant temperature of the earth to provide efficient heating and cooling. The systems operate by using water-source heat pumps which can be distributed throughout the building. Heat energy can be extracted from the earth in the winter, and added to the building. In the summer the process can be reversed. Unwanted heat is extracted from the building and added to the earth.

Department of Environmental Conservation (DEC)
New York State lacks traditional geothermal energy sources (volcanoes, geysers and hot springs). However, the earth absorbs almost 50% of the sun's energy. Geothermal heat pumps utilize the energy absorbing capacity of the earth to heat indoor air during the cold winter months and remove heat from indoor air during the warm summer months.

Environmental Protection Agency (EPA)
The constant temperature of the Earth creates underground sources of heat, hot water and steam which become fuel to produce geothermal energy. People have used various forms of geothermal energy for hundreds of years; modern technology accesses these underground reservoirs, steam deposits and hot air by drilling, and then using the heat or hot water directly or using it to create power. Geothermal energy represents an enormous, underused power source that provides clean, renewable energy in virtually unlimited supply.

U.S Department of Energy (DOE)
The U.S. Department of Energy (DOE) develops innovative technologies to locate, access, and develop the substantial geothermal resources available in the United States by advancing hydrothermal power production—where fluid flow and hot rock occur naturally—and enhanced geothermal systems technologies—where fluid is injected into deep, hot rock formations to create a geothermal reservoir. The U.S. Geological Survey estimates that, in the United States alone, 30 gigawatts of undiscovered hydrothermal resource capacity and more than 100 gigawatts of EGS potential lie deep in the subsurface—equivalent to 10% of today's energy needs.
