asked the Secretary of State for Energy what is his estimate, for each of the years since 1974, of the approximate percentage reduction in Great Britain's primary energy requirements which can be attributed to conservation measures, including the effects of pricing and publicity.
An account of the issues associated with the measurement of national energy savings is contained in written evidence submitted by the Department of Energy to the House of Lords Select Committee on the European Communities. For convenience, copies of this evidence are now available in the Library of the House. Subject to the qualifications given in the main text of the evidence the national savings estimates on present methods of estimation are given at annex I of the submission.
