Primary energy supply in Italy decreased by approximately ***petajoules in 2024, when compared to the previous year. Oil was the leading source of primary energy in the Mediterranean country that year. Primary energy supply describes the direct use of an energy source, without considering conversion or transformation processes.  
 Fossil fuels
Oil and natural gas remain the main primary energy sources used. In the last few years, the consumption of natural gas has become increasingly important in Italy, while oil consumption has decreased. However, oil surpassed natural gas in the primary energy mix during the global energy crisis in 2022 when gas prices increased to unprecedented levels.
Renewable energy
On the other hand, the consumption of renewable energy increased in 2022, amounting to some *** petajoules. The consumption of hydro sources (counted separately from renewables due to the use of large-scale plants) declined. Among renewable sources, solar power accounted for the greatest installed capacity and was the second source of renewable power in 2021, after water.
