Abstract
Geothermal energy takes a rather subordinate position among renewable energy sources. There are two possible sources for it: the radioactive decay of natural radio nuclides which causes the spread of heat onto the earth's surface, and the storage of solar energy in the top layers of the earth. For this reason, geothermal energy is available in many places and independently from the different seasons of the year, even if some regions do have a higher potential than others. This applies, for example, to the city of Ferrara in Northern Italy, they uses the geothermal source in an integrated system for district heating and cooling, together with the heat produced in a biomass plant for solid wastes and methane gas boilers as back-up.
