Electricity sector in Portugal

The electricity use in Portugal (gross production + imports – exports – losses) was 51.2 TWh in 2008. Portugal imported 9 TWh electricity in 2008. Population was 10.6 million.[1] In 2017 electricity was generated by 30% hydroelectricity, 27% natural gas, 22% wind, 20% coal and 1% solar.[2]

In Lisbon the energy payback time (see also EROEI) in the roof top solar photovoltaic (PV) technology is less than 2 years and less than in Sydney, Munich, Athens or Barcelona, but some more than in Madrid, Los Angeles or Ankara.[10]
