The latest available data are for the calendar year 2005 and are published in Table 7.7 of the Digest of United Kingdom Energy Statistics, 2006 as follows:
Renewable sources used (thousand tonnes of oil equivalent) Percentage of UK renewable energy supply Percentage of total UK primary energy demand Industrial wood 80.9 1.9 <0.1 Domestic wood 204.2 4.8 0.1 Co-firing of biomass with fossil fuels 830.7 19.6 0.3 Waste combustion 460.0 10.8 0.2 Landfill gas 1,420.8 33.5 0.6 Sewage gas 179.1 4.2 0.1 Other biofuels 362.4 8.5 0.1 Other renewable sources 704.4 16.7 0.3 Total energy supplied by renewables in terms of primary input 4,245.5 100 1.7 Total UK primary energy demand 246,884 — 100
The contribution of renewables to total UK primary energy demand has grown from 1.3 per cent. in 2003 to 1.5 per cent. in 2004 and 1.7 per cent. in 2006. Thermal renewable sources appear to make a larger contribution to energy supplied by renewables when measured in primary energy terms because, by definition, the primary inputs of non-thermal sources such as wind and hydro are equal to the electricity produced and there are thus no conversion losses.
