asked the Secretary of State for Energy what is the current extent of North Sea gas reserves; and what steps he is taking to conserve its use.
Recoverable reserves of gas from proven and probable discoveries were estimated, in the 1974 report to Parliament, as about 35 TCF (1012) cubic feet. My right hon. Friend will be publishing revised estimates in this year's report. Conservation strategy for gas is being formulated as progressively more information becomes available.
