HC Deb 18 January 1974 vol 867 c188W
Mr. Alan Williams

asked the Minister for Energy what variation in electricity consumption he estimates would arise from altering the clock in either direction by one hour, and by two hours.

Mr. Patrick Jenkin

I do not consider that such alterations would have a significant effect on electricity consumption as I am advised by the Electricity Council that the total number of units consumed in a 24-hour period is substantially the same irrespective of the time system in operation.
