- diesel – petroleum-based fuel as defined in the Biofuels Act 2007
- biomass – organic matter other than fossilised organic matter
- biogas – gaseous fuel derived or recovered from biomass
- biofuels – liquid fuel from biomass, including biodiesel and ethanol
- on-site renewable fuels – energy generated from a recognised energy savings activity at the site at which it is used, such as solar and wind.
