Geothermal power accounts for about 1.6-1.8% of the total
electric energy production in Italy and is about 7% of the total renewable energy produced in 2010.
The total energy from Geothermal was 5,660 GWh in 2015. Italy is the seventh country by geothermal installed capacity.
Italy was the first country in the world to exploit geothermal energy to produce electricity.
The high geothermal gradient that forms part of the peninsula makes potentially exploitable also other provinces: research carried out in the 1960s and 1970s identifies potential geothermal fields in
