§ Mr. Cohenasked the Secretary of State for Energy what is the estimated annual value of the low-grade heat which remains in water emerging from steam condensers in coal and nuclear power stations and which is unable to be put to economic use.
§ Mr. Michael SpicerLow grade heat emerging in water is equivalent to some 50 per cent. of the calorific value of fuel burnt in power stations. Any economic uses for such heat are a matter for the CEGB.
