Mines could be used to provide geothermal energy to local towns according to two engineers from the University of Oviedo, whose research is being published in the journal Renewable Energy. The method they have developed makes it possible to estimate the amount of heat that a tunnel could potentially provide.
Using geothermal energy also helps to reduce CO2 emissions, and is not dependent upon climatic conditions (unlike other renewable energies such as solar or wind power). Other advantages are that these facilities make use of a country’s own resources, do not require new developments on large sites, do not pollute the immediate environment, and are believed to be profitable over the long term.
Geothermal energy can be used directly in family homes, housing developments, swimming pools, fish farms, industrial units and other buildings.
