==Legal situation and subsidies==
Several legal and economic means have been used to enhance the market share of renewables. 
The UK uses [[Non-Fossil Fuel Obligation]]s (NFFO), a collection of [[Statutory Instrument|orders]] requiring the electricity [[distribution network operator]]s in [[England]] and [[Wales]] to purchase electricity from the [[nuclear power]] and [[renewable energy]] sectors. Similar mechanisms operate in [[Scotland]] (the Scottish Renewable Orders under the Scottish Renewables Obligation) and [[Northern Ireland]] (the Northern Ireland Non-Fossil Fuel Obligation). In the US, [[Renewable Energy Certificates]] (RECs), use a similar approach. German [[Energy transition|Energiewende]] is using feed-in tariffs. An unexpected outcome of the subsidies was the quick increase of pellet byfiring in conventional fossil fuel plants (compare [[Tilbury power stations]]) and cement works, making wood respectively biomass accounting for about half of Europe's renewable-energy consumption.<ref Name=woodecon/>
