REN21 the global network involving government officials, scientists, public institutions, NGOs and industry badociations, begins its 2018 Renewables Global State Report with this premise. The study, which gives an in-depth look at the trends and progress of green energy in 2017, highlights two different scenarios. In the first, we are witnessing a real revolution: the energy sector is indeed interested in a rapid transformation towards a renewable future . In the second, however, we realize that this change is not happening at the speed our planet would need.
The good news is that the signals that give hope to the first scenario are many: alongside the most developed countries – United States, Europe, China – Countries like India, Rwanda, Chile and Egypt is investing considerable resources in renewable energies. Bottom-up initiatives, decentralized solutions and start-ups make a considerable effort in this direction. Another strong signal comes from photovoltaics which, in 2017, installed 98 GW of new capacity: 29% more than the previous year, surpbading coal, natural gas and nuclear energy
In this context, Italy plays a very respectable role placing itself in fourth place for capacity per capita and the fifth (preceded only by China, the United States , Japan and Germany) by the accumulated capacity. In 2017, with 19,950 GW installed capacity solar energy contributed nearly 9% to electricity generation at the national level.
