Funnily enough, the hon. Gentleman repeats a common misconception about renewables. Although an individual wind turbine in one place might provide an intermittent supply, in managing energy demand we are interested in the aggregate of all renewables over the economy. First, there are few times of day without wind, sun or waves. Secondly, tidal power is—surprisingly enough—incredibly predictable centuries ahead.
We need to be able to predict the aggregate of renewables. I agree that it will not be level throughout 24 hours, but neither is energy demand. We do not need inflexible sources that are simply on all the time, which and that we are stuck with. We need flexibility to meet the fluctuations of demand through the day. We would be lumbered with the nuclear input and obliged to use it, whereas we need flexible sources such as gas-fired stations with carbon capture or renewables, which can to some extent be stored and used at later points. Let me use the Severn barrage as an example: although the tides are predictable, there are ways in which the water can be pumped when there is excess energy and used when it is needed. There are more flexibilities than are commonly understood.
