The document discusses the potential for green energy and renewable resources in Portugal and the European Union. It notes that current energy demands cannot be met through fossil fuels alone. It then outlines various renewable energy sources like organic waste, wastewater, solar, wind, and biomass and estimates their potential energetic output in Portugal and the EU each year.
