Having regard to the relentless rise in the cost of the production of energy from coal, oil and other sources, will my right hon. Friend take advantage of the sunshine that will follow a massive Conservative majority in the general election to commission more intensive research into the production of energy from solar systems?
I confirm to my hon. Friend that we are concentrating our available research and development funds on the most promising of the renewable technologies for the United Kingdom, which are wind, geothermal and passive solar design. Among the solar systems, my Department is concentrating on the passive solar design, which is the most promising means of exploiting solar energy in the United Kingdom.
The Government's programme for alternative sources of energy is flexible, and, of course, were such a breakthrough to take place, the Government would take account of it.
