Renewable energy source for today situation - GeoExchange systems

An increased utilization of renewable energy sources in the heat and electricity generation is one of priority tasks of the Slovak Republic to boost the use of domestic energy potential and thus to decrease the Slovakia's dependence on imported fossil fuels. For this reason the experimental workplace "Economic Research Centre for Renewable Energy Sources and Distribution systems" was founded last year. In the article we deal with heat pumps offering the most energy-efficient way to provide heating (central and water heating) and cooling in many applications, as they can use renewable heat sources in our surroundings. It is argued that heat pumps are very energy efficient, and therefore environmentally benign. Within good conditions the energy from low-potentional heat, in other way unusable, is used for the price of supplied energy for heat pump performance. This article determines applicability of this system supports utilization of electric energy low tariff rate, which is also valid for the other electrical appliances on the real administrative building.
