• Mining and industry

Portugal depends heavily on the importation of petroleum and petroleum-based products.

Coal, the production of which has decreased since the mid-1990s, accounts for about five percent of the country's energy use.

More than half of Portugal's electricity is provided by renewable energy with the largest hydroelectric power station at Alto Lindoso dam and around 100 smaller hydro centres elsewhere.

Tungsten, tin, chromium and other alloy metals are mined in commercial quantities and most of the tungsten is exported.
