asked the Secretary of State for Energy what is the current expenditure budget on energy conservation technology by the support unit at Harwell; and what proportion is being allocated on research and development into utilisation of reject heat by Central Electricity Generating Board power stations.

Expenditure during 1974–75 on energy conservation technology was £88,000, and for 1975–76 this is expected to double. No part of this expenditure is allocated to research and development into utilisation of reject heat; however, a small part of the unit's assessment work does relate to this subject.
