Abstract
In Italy renewable energy sources (RES) covered the 18,2% of the gross final energy consumption in 2019, thus, exceeding the target of 17,0% renewables, assigned for the year 2020 by the Directive 2009/28/CE. While electricity and transport sector showed an increase of RES consumption, in absolute terms, a slight reduction of thermal energy production from RES has been observed. However, this last decrease was compensated by a greater decline of gross final energy consumption; consequently, all the three sectors were characterized by an increase of RES penetration, in percentage terms. Industry is one of the main energy intensive sector in Italy, as it accounts for around 21% of final energy consumption; however, the reduction with respect to the previous year (-0,9 %) and the continuous decline of industrial sector energy intensity show that we are exploiting primary energy sources more and more efficiently.
Energy efficiency, indeed, will play a key role to achieve the target of net-zero emissions in the EU energy systems by 2050
