In the Independent newspaper (London, Monday 23 February) I argued that we may need to accept some new nuclear power stations. I put forward the view that the trench warfare between the pro-nuclear groups and those that support renewables means that progress towards 'decarbonising' electricity generation in the UK is too slow. We probably need to invest in many different types of non fossil-fuel generation as rapidly as we can if we are to meet the tough targets for UK emissions reduction so painfully won by groups such as Friends of the Earth. We no longer have the luxury of ruling out nuclear expansion.
