Gas and wind power in Sweden today
For a long time, Swedish industry and the transport sector have been dependent on imported oil – over 90 per cent of vehicles are still powered by petrol or diesel. Oil accounts for almost 30 per cent of Sweden's total energy supply (around 170 TWh). Biogas and natural gas together account for approximately 3 per cent (15 TWh).
Biogas is a completely renewable energy source that does not generate any climate-impacting emissions. It is created through anaerobic digestion of crops or food residue and through gasification of forest residue. The economically realisable potential of biogas is estimated at 22 TWh through anaerobic digestion and a further 60 TWh in conjunction with thermal gasification. Biogas can be transported together with natural gas in the Swedish gas grid.
Wind power is facing significant expansion. In 2015, 16.6 TWh of wind power was produced in Sweden and the plan is for production to increase to 30 TWh by 2020. But up to now expansion is being curbed by bottlenecks in the electricity infrastructure and by the fact that wind energy cannot be stored on a large scale. There is also increasing interest in intermittent energy sources, such as solar power and wave power.
