The raw material base for bioenergy is diverse. Also the gained energy sources, the conversion processes and the forms of final energy offer a wide variance.
Biomass is available in solid, liquid and gaseous form for heat production, for generating electricity and for the production of biofuels. With a variety of technologies and processes in many different performance classes energy can be derived from biomass.

For example stoves and pellet heating systems in private households provide bioenergy in the form of heat. Both boilers in industry and commerce fired with residual forest wood chips and wood heating plants for local heating supply in villages and cities generate biogenic heat.

Bioenergy is also produced from scrap wood and residual wood from industry in biomass power plants and by co-incineration of biomass pellets in coal-fired power plants.

Biogas from agricultural biogas plants can be used versatile for heat and electricity supply or as fuel depending on the treatment and conversion processes.

Also the rapeseed oil pressed on farms and used as fuel in tractors is bio-energy, as well as biodiesel and bioethanol, which are added pro rata of the petroleum industry to the diesel and petrol. And last but not least the energy produced from organic waste, sewage gas and landfill gas is delivered into account of the bioenergy.
