Portugal relies heavily on imported fossil fuels for its energy needs due to limited domestic fossil fuel resources. While some coal and uranium are produced locally, over 80% of Portugal's energy comes from imported oil, natural gas, and coal. Renewable sources like wind, solar, hydroelectric, and biomass are increasingly important to Portugal's energy mix as the country aims to reduce dependence on imports and pollution. Wind power in particular has expanded significantly, with over 3500 MW of installed capacity nationwide. Portugal has good natural conditions for harvesting energy from the sun, waves, and water resources.
