Electricity Generation by Energy Sources in Mainland Portugal
(January until December 2017)
In 2017, the renewable electricity accounted for 42.1% (22,956 GWh) of the Portugal Mainland’s total generation. This value contrasts with last years’ share when the renewable electricity represented around 50% of the Portuguese electricity production.
The reason for this RES-E reduction is due to the 2017’s several drought that is affecting the hydroelectricity generation.
