produced the most bioelectricity in 2023, feedstocks in the form of renewable municipal solid waste and other liquid biofuels for heat and power are used to a small extent. This section provides an overview of bio-heat production in centralised heat generation in the EU, primary solid biofuels, i.e. solid biomass (forest and agricultural residues, wood pellets and various wastes, including municipal solid waste). Primary solid biofuels were the most used feedstock with 5 Mtoe in 2000, peaking at 17 Mtoe in 2021, and declining to 15.5 Mtoe in 2023 mainly due to declining household heating consumption. While primary solid biofuels grew in absolute terms between 2000-2023, their share decreased from 87% in 2005 t0 around 77% in 2023, because the growth rates of renewable municipal waste and biogases were higher, increasing their contribution to the mix. The use of renewable municipal waste was growing steadily over the period 2000-2023, which is linked to the use of waste in combined heat and power (CHP) plants. The use of biogases grew from 1% in 2005 to 4% in 2023. This is due to the increasing use of waste heat in biogas plants, which allows for additional sources of revenue, in many cases supported by EU
