Geothermal – the heat from the earth

ECOHZ is now proud to offer its customers renewable electricity from geothermal production, documented with Guarantees of Origin. Geothermal electricity is a renewable and sustainable energy source comparable with better known renewable sources such as hydro, solar, wind and bio.

Geothermal electricity generation utilizes the heat from the earth 2-3 kilometers under the ground. Here water meets heated rock and is turned into steam. Drilling holes transfer the steam into turbines, which again generate electricity using a regular generator. Beside generation of electricity, geothermal energy can be utilized for various applications such as heating and cooling, food preparation, hot spring baths and spas, agriculture, aquaculture and industrial processes. Using geothermal energy for heating and bathing can be traced back to ancient Roman times.

Only few sites have the potential of Geothermal Energy and the installation cost of a steam power plant is quite high. In Europe geothermal generation is mostly used in Italy and Iceland, which jointly has in excess of 1400 MW of installed production capacity.

Geothermal t is a non-polluting and environment friendly source of renewable energy with no wastage or generation of by-products. Geothermal power plants have a low land-use footprint and do not represent a hazard for the natural surroundings. The maintenance cost of geothermal power plants is low and unlike other sources of renewable energy, it is not dependent on weather conditions.

ECOHZ sources its geothermal electricity from Iceland – the home of the geysers. Geothermal electricity generation has played a big part in making Iceland successfully convert from being a poor country, dependent on coal and peat imports, to being self-sufficient on electricity. The environmentally friendly generation of geothermal energy has further enabled Iceland to become a preferred location for new energy intensive industries such as aluminum production and steel smelting.
