According to table 5.1 of BERR’s latest “Energy Trends” publication (http://www.berr. gov.uk/files/file40156.pdf), the total amount of electricity supplied in the UK during 2005-06 was as follows:
GWh (a) coal 136,670 (b) oil 5,540 (c) gas 143,730 (d) nuclear 75,000
Apart from renewables, it is the Government’s policy not to target the proportion of electricity generated by different fuel types. These are commercial decisions for generators in a market framework designed to incentivise security of supply and carbon dioxide abatement.
