Data from Portuguese power company Redes Energeticas Nacionais (REN) shows that renewable energy plants generate enough electricity to cover 59% of Portugal's electricity needs between January and October 2021.

Hydropower and wind power contributed the most, accounting for 25% and 24% of national demand, respectively. Biomass energy is a close second with 6% and solar photovoltaics (PV) with 4%.

Non-renewable electricity accounts for 31%, with natural gas accounting for 29% and coal 2%, according to REN. Energy imports meet the remaining 10% of domestic consumption.

In October alone, renewable power generation provided 44% of domestic consumption. Non-renewable resources and imports accounted for the remaining 34% and 22%, respectively.

The utility noted that Portugal's overall electricity consumption was up 1.5% year-on-year so far this year, or 2.2% when temperature and the number of working days were taken into account.
