According to REN - Redes Energéticas Nacionais, of the 59 percent of electricity consumption supplied by energy production from renewable sources last year, 26 percent corresponds to wind energy, 27 percent to hydroelectric, 7 percent to biomass and 3.5 percent to photovoltaic.

In the case of photovoltaic solar energy, although it continued to be the least significant among renewables, REN highlighted its strong growth (37 percent) compared to the previous year.

As for the 31 percent of electricity consumption supplied by non-renewable energy production in 2021, 29 percent refers to coal, with the last plant closed at the end of November (Pego, in Abrantes) representing less than 2 percent.

The remaining 10 percent corresponds to imports.
