The Department for Children, Schools and Families was formed via a machinery of Government change in June 2007; therefore a complete response to the question above can be provided only for financial years 2007/08, 2008/09.
In 2007/08 the Department consumed 23,763,917 kilowatt hours of energy (gas, electricity and steam) at a cost of £1,489,366 at the four HQ sites in London, Darlington, Sheffield and Runcorn.
In 2008/09 the Department consumed 21,286,750 kilowatt hours of energy (gas, electricity and steam) at a cost of £1,683,021 at the four HQ sites in London, Darlington, Sheffield and Runcorn.
While a green energy tariff is in place for Darlington electricity it is not possible to determine the level of energy generated from renewables sources for each of these years.
