HC Deb 09 March 1982 vol 19 cc373-4W
Mr. Gwilym Roberts

asked the Secretary of State for Energy, in the light of his answer to the hon. Member for Cannock of 15 February, Official Report, c. 12, if he will develop a mechanism to measure what part of any savings achieved in energy consumption was due to investment in structural conservation measures.

Mr. Mellor

Work on improving our analysis of changes in energy consumption, and in isolating the effects of price-related energy conservation, is continuing. However, there is as yet no satisfactory mechanism for separating out the effects of structural conservation measures on total energy demand.
