§ Mr. Penhaligonasked the Secretary of State for Energy what is his estimate of the total energy in British thermal units lost in the electricity generation process due to various cooling systems.
§ Mr. EadieThe amount of heat which had to be rejected to the cooling water for the whole of the electricity generation system in England and Wales in 1973–74 was approximately 1,300 million million British thermal units.
§ Mr. Penhaligonasked the Secretary of State for Energy if he will list the percentages of the total United Kingdom energy consumption of each primary fuel used in the generation of electricity for each year since 1965; and what is the estimate for 1974 and 1975.

Because of the uncertainties about the supply, I am unable to estimate future consumption in these precise terms.
