The figures used in the answer of 14 March reported that 206,087,269 kilowatt hours, representing 63 per cent. of the Departments energy came from renewable resources. This figure included that element of ‘green’ energy that is supplied from good quality combined heat and power, which whilst sustainable, does not meet the criteria for renewable energy. This combined figure for ‘green’ energy is used internally to highlight the decreasing use of standard “brown” electricity and was therefore used inadvertently.
For 2005-06 the Department used 175,174,178 kilowatt hours of energy acquired from renewable sources—accounting for 53.5 per cent. of the total electricity consumption. The remaining 30,913,091 kilowatt hours of ‘green’ energy was supplied from good quality combined heat and power.
