According to the Swiss government, final energy consumption in Switzerland slightly increased in 2019 (+0.3%) due to cooler temperatures, economic growth (+0.9%), demographic growth (+0.7%) and increasing fleet of motor vehicles (+0.8%). This rising trend was offset by continued energy efficiency and substitution effects.
In 2019, the consumption of transport fuels, which cover nearly 49% of the final energy consumption, slightly decreased (-0.8% for gasoline and stable for diesel). Electricity consumption declined by 0.8% and covered less than 25% of the final energy consumption, while gas consumption increased by 2.6% (nearly 14% of the final energy consumption). Final consumption of wood biomass (4.7% of the final consumption) increased by 1.1%, while that of coal fell by 11% (less than 1% of final energy consumption).
Power generation in Switzerland grew by 6.4%, thanks to an 8.4% increase in hydropower generation (over 56% of the power mix) and a 3.5% hike in nuclear generation (35% of the power mix). Thermal power generation only increased by 1.4% to 4.2% of the power mix, a share similar to that of non-hydropower renewables (+11% in renewable power generation in 2019).
