Energy-intensity Ratio

HC Deb 31 January 1992 vol 202 cc722-3W

Mr. Alan W. Williams

To ask the Secretary of State for Energy if he will estimate Britain's energy-intensity ratio for each year since 1962; and what are his projected estimates for each year until 2010, based on current Government policy.

Mr. Wakeham

Since 1962 the energy ratio, defined as the ratio of primary energy demand to gross domestic product, has taken the following values:

Year	Value
1962	0.89
1963	0.88
1964	0.86
1965	0.87
1966	0.85
1967	0.84
1968	0.83
1969	0.83
1970	0.85
1971	0.83
1972	0.82
1973	0.80
1974	0.77
1975	0.75
1976	0.75
1977	0.74
1978	0.72
1979	0.72
1980	0.69
1981	0.67
1982	0.66
1983	0.64
1984	0.62
1985	0.62
1986	0.61
1987	0.59
1988	0.58
1989	0.58
1990	0.59

Projected future values of the energy ratio will be included in a forthcoming publication containing revised projections of CO₂ emissions and energy demand. These were described in a parliamentary answer on 6 December 1991, at columns 258–59.
