Geothermal Energy is generated and stored in the earth, under the soil. It is earth heat converted to energy. This kind of energy has been used since ancient Roman times from hot springs, and as other environmental friendly energy sources it is nothing new, but just modernized. Geothermal power is cost effective, reliable, sustainable and environmentally friendly. This alternative suits well for all types of energy consuming areas as industry, greenhouses and homes.
Geothermal sources under the soil releases greenhouse gases, but the emissions are much lower that fossil fuels and is a good alternative to replace usage of fossil fuels. This energy alternative can easily cover all of the humanitys needs. It is an energy source that will grow significantly the coming years as the investment costs has reduced and people has showed interest to pay more for renewable energy.
Two sources for geothermal energy are magma and hot water springs
Thermal energy plants was before built only where high temperatures were to be found close to the surface, but thanks to developed technology as e.g. better drilling equipment, the areas are today wide spread. Thermal energy today is converted from hot waters to magma. Almost anywhere the temprature three meters under the soil is between 10-16 °C (50-60 °F) and this is enough to install a heat pump.
