Conservation ("Save It" Appeal) Mr. Arthur Lewis asked the Secretary of State for Energy how much money has been spent to date on the "Save It" campaign; and what has been the actual or estimated energy saving during the same period. Dr. John Cunningham The "Save It" campaign was launched on 20th January 1975. Approximately £7·7 million has been spent so far on all forms of publicity.Energy savings, as a result of the Government's energy conservation programme including the influence of energy prices, have been estimated to be about 6 per cent. in both 1975 and 1976, but the margins of error are very wide. Final estimates of energy consumption during 1977 and the level of savings achieved are not yet available.On the basis of interim estimates, existing policies are believed to have contributed to energy savings worth approximately £1,800 million in 1976 cost terms during the period of the "Save It" campaign.
