To ask the Minister of State, Department for Transport what the estimated (a) amount and (b) cost was of energy used in his Department and its agencies in each year since 1997; what proportion of the energy used was generated from renewable sources in each of those years; and if he will make a statement. (317236)

The Department for Transport was formed in 2002 and therefore no records exist for the Department prior to that date.

The following tables show the electricity, gas and other fuels used by the Department for Transport and its Agencies since 2004-05.

The following table gives the percentage of electricity consumed by the Department that came from renewable resources for each of the last five years.

The reducing percentage of electricity from renewable resources depicted above is as a result of a change in the main supply contract from Buying Solutions which now has a reduced renewable allowance in order to ensure renewable energy is available in the private sector.

Part of the progressive increases shown in the above tables is accounted for by improvements in the standard of data collection.

The following table provides the total annual cost of the energy used in the above tables.

In addition to the above listed energy use the Highways Agency is responsible for the provision of roadside technology and lighting which incurred £23.9 million in energy costs in 2008-09. It is not possible to provide consumption data for this facet of departmental activity.
