Only solar power is quite pervasive, as Portugal is known to have a very high average number of days of solar exposure. I live some 3/4 kms of a quite big solar power array that is the source of the majority of electrical power in the nearby houses. And in Alentejo (just north of Algarve), you can find the Amareleja power station which in 2008 was considered the largest solar power array in the world (https://en.wikipedia.org/wiki/Moura_Photovoltaic_Power_Stati...).
Portuguese solar can take a big bite out of French peak demand. The sun sets on Marseilles, and everyone's coming home for dinner, but there's still some sun in PT.
