Low temperatures thermal energy - a huge market and potential environmentally friendly

In everyday life, the concept of thermal energy is associated, in outlook, with areas or facilities which are distinguished by relatively high temperatures. In the shadow of this perception, we are tempted to not see the quantities of heat that benefits all of us, for personal convenience or for carrying some activities. The reason for this negligence is that the heat enter our lives at relatively low temperatures, which is not perceived as dangerous. Required amount of heat at low temperature are huge and are largely obtained on account of adequate fossil fuels quantity burning. This conduct can not be considered environmentally friendly because, on the one hand, leads to high rates of diminishing fuel reserves and, on the other hand, increase the rates in which terrestrial atmosphere is loaded with fossil carbon. However, "Mother Nature" is generous and gives us the opportunity to obtain large amounts of heat through smart exploitation of local resources present practically in any area. This work aims to analyze the thermal energy at low temperature consumption under three aspects. The first of these concerns the structure and dimensions of the particular market. The second issue concerns the "supply" of available heat in the environment. Finally, the third aspect concerns the technical possibilities available for an intelligent exploitation of natural heat supply to cover a portion of alleged market.
