§ Mrs. Dunwoody
To ask the Secretary of State for the Environment how much money was invested in energy efficiency in the United Kingdom in(a) 1991 and (b) 1992; and if he will make a statement.
§ Mr. Maclean
A large part of the investment in the United Kingdom economy will have some effect on improving energy efficiency, although it is not possible to separate out an aggregate total of investment specifically directed at this purpose. However, in 1991 the amount of energy required per unit of GDP was some 18 per cent. lower than in 1979.
