Afaik, mostly relevant sources of geothermal power in Portugal are in the Azores islands (wonderful place to visit, btw). Regarding wind power, the highest locations are on the northern part of the country (above Lisbon), so most wind turbines are there. Same thing for water dams, as it is natural that most rivers and streams are on mountain's valleys. 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_Station https://en.wikipedia.org/wiki/Moura_Photovoltaic_Power_Stati...).
