Biofuel analysis which shows the proportion of energy generated from organic matter could help community energy schemes to qualify for incentives from the government.
Climate change minister Greg Barker this week outlined some of the opportunities open to organisations, businesses and community-level action groups looking to put green energy systems in place.
Among the options open to them are combined heat and power plants, which can run on biomass and other renewable waste materials.
Mr Barker said: "Community groups, businesses and organisations can get together to build a cleaner, greener future.
"They can generate their own heat and electricity, and their own profits."
Guidance from the London Energy Partnership shows how
biofuel analysis can help organisations to qualify for certificates under schemes like the Renewables Obligation.
When generating electricity from renewable resources,
biofuel composition of no less than 90 per cent biomass must be used, the advice from the partnership states.
