asked the Secretary of State for Energy if he will publish his latest estimates for energy saving through conservation for each of the next 10 years, identifying the amount of saving from each conservation method for each of those years.
It is not possible to make such detailed predictions. In "Energy Projections 1979" a conservation allowance of about 20 per cent. in demand for useful energy was made in the projections for the year 2000. The comparable figure for 1990 would be about 15 per cent.
