To ask the Secretary of State for International Development what percentage of the electricity used by his Department was generated from (a) renewable sources and (b) on-site microgeneration facilities in the last period for which figures are available. (104322)

The proportion of energy used in our UK buildings generated from renewable sources for 2005-06 was 95 per cent. The remaining 5 per cent. relates to a building which we are about to vacate. None of our energy is currently generated from on-site microgeneration, but we are currently carrying out feasibility studies into options such as combined heat and power (CHP) units, tri-generation systems, and biomass heating systems for both of our remaining buildings.
