§ Mr. Favellasked the Secretary of State for Energy by how much productivity has increased in (a) the coal mining industry, (b) the electricity industry and (c) the gas industry since the end of 1980; and how these figures compare with the economy as a whole.
§ Mr. Buchanan-SmithNo specific productivity indices comparable with those compiled and published for the economy as a whole are readily available for the coal mining, electricity and gas industies. However, figures of coal output per man-shift at NCB mines are published monthly inEnergy Trends, copies of which are available in the Library.
