I reject the hon. Gentleman's comment about nuclear power. There is absolutely no reason why expenditure on renewables research and development should bear any proportional relationship to nuclear expenditure. Each energy technology requires a different level of investment to carry out the necessary R and D and to develop it for commercial use. However, I am grateful to the hon. Gentleman for asking this question, because it has provided the House with an opportunity to learn that we have record levels of R and D expenditure on renewables.
