Total installed capacity in 2001 was 127 MW, of which about one-fourth was hydroelectric. Production of electrical energy in 2000 amounted to 467.7 million kWh, of which 57.5% was from fossil fuels, 25.7% from hydropower, and the rest from other renewable sources. Consumption of electricity in 2000 was 6.2 billion kWh. Electrical production has increased since the dams at Esch-sur-Sûre and Rosport were completed. The hydroelectric plant at Vianden has the largest pumping station in Europe. Virtually all of the country's hydroelectric potential has now been put to use. The steel industry consumes 80% of total industrial energy demand.
