Fossil Fuels & the Non-Fossil Fuels Obligation (NFFO)

Fossil fuels are defined as any naturally occurring fuel, such as coal or oil, formed by the decomposition of prehistoric organisms.

The 1989 Electricity Act requires the electricity supply companies of England and Wales to purchase electricity from specified amounts of non-fossil fuel generating capacity. Costs in excess of those arising from generation using fossil fuels are charged to customers through the Fossil Fuel Levy, which is a supplement on electricity consumption. Under existing legislation NFFO (see below) is due to continue until 1998. The level of subsidy is such that renewable projects assisted by NFFO should recoup their capital costs by then.

Nitrogen Oxides

These are oxides of nitrogen which can cause atmospheric pollution. The main sources of man-made nitrogen oxides are the combustion of fossil fuel (in power generation, heating plants and motorised vehicles).
