Wind power
Portugal produced 11% of electricity with wind power in 2008 and had the average year capacity of 14% of wind power in the end 2010. Wind power capacity was 3,357 MW in end 2009 and 3,702 MW in end 2010.
Solar power
Solar electricity production with the photovoltaic arrays is pollution-free. It is easily integrated into the urban environment, close to consumption needs. It does not emit greenhouse gases, it does not dip into finite fossil fuel resources. In Lisbon the energy payback time 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.
