Mining and industry
Portugal depends heavily on the importation of petroleum and petroleum based products.
Coal, the production of which has increased since the mid-1980s, accounts for about 5 percent of the country's energy use.
One-third of Portugal's electricity is provided by hydropower.
Tungsten, tin, chromium and other alloy metals are mined in commercial quantities and most of the tungsten is exported.
