Where? Our renewal energy • • • • • • Water (rivers) Wind Sun Geothermal Waste/disposables Waves Translated by GOOGLE Rivers (Dams) • We call it “white gold” (opposite to “black gold” from petroleum) Go GOOGLE EARTH Wind (farms) Go GOOGLE EARTH SOLAR POWER PLANTS AMARELEJA - MOURA BRINCHES - SERPA Rosário - Almodovar Ferreira do Alentejo Go GOOGLE EARTH Geothermal AZORES Pico Vermelho (10MW, 72GWh/year) Ribeira Grande(13MW, 98.5GWh/year) 41% of the electrical energy in the island, is from this two power plants!!!
