At 911,550 terajoules (TJ), Switzerland's final energy consumption in 2010 was 4.4% higher than in 2009 and significantly higher than the previous record level attained in 2008 (895,250 TJ). The demand for energy was driven by three main factors:
Consumption of the combustibles extra-light heating oil (+5.5%) and gas (+10.8%) increased sharply while consumption of vehicle fuels rose only slightly. Sales of diesel (+3.9%) and aviation fuel (+5%) increased substantially whereas the consumption of petrol fell (-3.6%). The trend to substitute petrol with diesel as a vehicle fuel continued unabated. Demand for heavy heating oil declined sharply (-17.7%) while more petroleum coke was burned (+23.3%). Electricity consumption rose by 4.0% (see the media release of 13.04.2011).
In 2010, 7.7% more energy was produced from wood. There was a major increase of 21.1% in the use of ambient heat using heat pump technology again underlining the clear trend toward this type of heating. High growth rates were experienced in the district heating (+12.7%), solar heat (+13.5%) and biogas (+7.3%) sectors. After a sharp decline of almost 29% in 2009, biofuels made a strong comeback with a 20.0% increase. Use of industrial waste (+5.8%) and coal (+2.1%) to produce energy also increased although there had been a decline in the previous year.
Beginning with the current overall energy consumption statistics, the energy consumed by heat and power cogeneration plants (CG) will no longer categorised as energy consumed by industry but rather as energy for energy conversion; gas, extra-light, medium and heavy heating oil, industrial waste and wood are all used as energy sources in the operation of CG plants. Revising the statistics in this manner guarantees Switzerland's overall energy statistics remain consistent with the international standards (IEA, EU and UNO). This year the statistics dating back to 1999 have been adapted. Those dating back to 1990 will be recalculated next year.
This adaptation of the statistics has no effect on Switzerland's overall energy CO2 balance because the energy balance and thus the CO2 emissions of the energy industry remain unchanged.
The Swiss Overall Energy Statistics 2010 will be released in print and on the Internet at the beginning of August 2010. Until then the initial summary is available at www.bfe.admin.ch.
