Natural energy from the earth looks very costly compared to traditional types of heating, but there are not enough facts to support this argument. A typical natural gas furnace with central air-conditioning costs about the same as the heat pump, although gas lines and chimney costs should be accounted for. The main installation cost difference comes from the loop in the group, well water transfer unit, excavation and drilling.
Geoexchange technology is also known as geothermal, ground-source heating or heat pump. It offers unlimited renewable solar energy stored underground - about 50% of the sun's energy is usually absorbed by the ground. It is a simple concept: during winter, heat energy gets drawn out of the earth through pipes, known as a loop, which contains antifreeze solution to prevent freezing as the ground's heat is transferred to the home "heat pump" (basically a compressor and heat exchanger).
Gas fired power plants
Power stations using gas have a much smaller carbon footprint than that of coal. Moreover, the gas is piped straight to the power stations, lowering secondary carbon emissions because no transportation is involved in its delivery.
