For ease of reference, details relating to my Department and Executive Agencies for each of the last five years are reproduced in the table.
Energy consumed (KWh)
Energy spend (£)

The data in columns two and three are aggregates for my Department and its Executive Agencies, the data in column four relates solely to my Department. Disaggregated data could be obtained only at disproportionate cost.
Definitive quantification of the amount of energy saved through energy efficiency measures is affected by a number of variables such as weather conditions, floor area and number and activities of building occupant, and could be provided only at disproportionate cost.
My Department's energy is managed within an ISO 14001 certified environmental management system, and energy policy is based on the environmental policy objectives of conserving natural resources and reducing emissions of greenhouse gases.
To ask the Secretary of State for Trade and Industry what proportion of the United Kingdom oil supply was refined within Wales in the last three years; and how much this represented per head of population.
