Estonia produces about 75% of its consumed electricity. In 2011, about 85% of it was generated with locally mined oil shale. Alternative energy sources such as wood, peat, and biomass make up approximately 9% of primary energy production. Renewable wind energy was about 6% of total consumption in 2009. Estonia imports petroleum products from western Europe and Russia. Estonia imports 100% of its natural gas from Russia. Oil shale energy, telecommunications, textiles, chemical products, banking, services, food and fishing, timber, shipbuilding, electronics, and transportation are key sectors of the economy. The ice-free port of Muuga, near Tallinn, is a modern facility featuring good transshipment capability, a high-capacity grain elevator, chill/frozen storage, and new oil tanker off-loading capabilities. The railroad serves as a conduit between the West, Russia, and other points.
