Italy has experienced significant growth in renewable energy over the past two decades, with installed capacity increasing by 267 percent from 20,222 MW in 2004 to 74,303 MW in 2024. This is the finding of the 20th edition of Legambiente's Comuni Rinnovabili report, produced with the GSE, which highlights an increasingly widespread energy transition across the country. The protagonist of this growth is photovoltaics, which has reached a capacity of 37,085 MW thanks to more than 1.8 million installations, with 276,000 new installations in 2024 alone. Also notable is the increase in wind power, which has increased by 11,890 MW and now has 6,130 installations. Despite the progress, Legambiente stresses the need for acceleration in Italian energy policy to close the gap with other European countries such as Spain and Germany. Katiuscia Eroe, Legambiente's energy manager, highlights how greater development of renewables could lead to lower bills and a share of green energy above 60 percent. To achieve these goals, according to the association, we need clear policy choices, consistent regulations and the overcoming of current authorization blocks that slow down investment. The work of Italy's energy communities and businesses, however, represents a solid foundation on which to build a more sustainable future.
