About 74% of the 3.429 GWh (gigawatt-hours) of electricity generated in March in mainland Portugal had a renewable origin, according to data from the Portuguese renewable energy association (APREN), released today. APREN explained that “the 12.3% increase compared to March 2022 is due to the decrease in fossil incorporation, with 668 GWh having been produced, compared to 1.557 GWh in March 2022.”
