Renewable energy kept Portugal’s lights on for four consecutive days last week.
The clean energy milestone was revealed by System Sustainable Land Association (ZERO) and Portuguese Renewable Energy Association (APREN), which analysed data from the National Energy Network (REN).
Electricity usage in the country was fully covered by wind, solar and hydro power between 6.45am on Saturday, 7th May and 4.45pm on Wednesday, 11th May.
ZERO stated: “This corresponds to a total of 107 hours at a time where it was not necessary to resort to any source of non-renewable electricity production, particularly the production of thermal power plants to coal or natural gas.”
Last week the UK generated zero power from coal-fired plants for a few hours.
