[en] 2011 was marked by the continued increase in energy prices, raising the country's energy bill and weighing on the activity of businesses and on household budgets. The effect on households was, however, mitigated by the exceptionally mild weather conditions in 2011, which reduced needs for heating. Corrected for climate variations, primary energy consumption increased slightly, its level remaining below pre-crisis ones. Final energy consumption was stable, resulting from contrasting changes: decrease in industry, construction and agriculture, in spite of higher output, and increase in the service, residential and transport sectors. National primary energy production increased in 2011, reaching a new record close to 139 Mtoe. It benefited from high levels of nuclear and wind generated electricity. Conversely, energy production from several key renewable sources - hydro, fuelwood and biofuels - saw a downward trend. (authors)
