AFFORDABLE AND CLEAN ENERGY INDUSTRY, INNOVATION AND INFRASTRUCTURE RESPONSIBLE 12 CONSUMPTION AND PRODUCTION CLIMATE 13 ACTION Circular economy – Focus Wind o Inputs Material Main materials used: Steel Concrete Fiberglass Copper Aluminium - ∞ Useful Life 25 years average lifetime > Expected volume at end of life considering the installed capacity¹: - 970 MW before 2030 ~ 1.700 MW 2031-35 ~ 4.000 MW 2036-40 ~ 11.000 MW after 2040 enel New Life Cycle Current recyclability of WTGS ~ 80% (steel, alumiunium, copper already fully recycled) Estimated recyclability of WTGs at 2025 90% - (improvement in the recycling of fiberglass) KEY INITIATIVES (examples) New solutions for wind 1. End of 2022. Development of new materials more sustainable, performing and recyclable through collaboration with start-ups and major players (e.g. wood based tower with a potential CO2 reduction per KWh of 90%). Recycling plant for wind blades In Spain (capacity 8.000 tons/year), and in Italy (capacity 3.000 tons/year) With the aim of reusing recycled fiberglass back into the wind energy sector and other sectors that may require such composites. 154
