Bioenergy is energy derived from biofuels, which is defined according to Swedish Standards as "fuels where biomass or peat is the original material. The fuel can have passed through chemical processes or transformation or other use". Biomass is according to the same Standrads "material with biological origin that has not, or only to a modest extent, been chemically transformed".
That the Swedish Bioenergy Association (Svebio) was founded in 1980, after the oil crisis in 1979. At that time bioenergy accounted for 10 % of the energy supply in Sweden. Bioenergy was not yet commercial and a major part of the bioenergy was used internally in the wood industry.
