The national installed capacity of renewable energies between 2006-2021 has increased significantly, especially wind and photovoltaic energy. As pointed by Intermoney, they have grown 139% and 9,110%, respectively. Similarly, the installed conventional energy (coal and fuel + gas) has decreased with declines of 53% and 73%, respectively. Spain would also exceed the European targets for the penetration of these energies with 42% compared to the European 38-40%. For the experts of Renta 4, the very strong operational and financial growth of the companies will be coupled with the growing trend of ESG.
