Well, the Cabinet Secretary clearly doesn’t understand that part of the problem with reliance on renewables is that the lights may well not come on when you press the switch. At the moment, the National Grid is generating 3.33 per cent of power from renewables, compared with 17.32 per cent from coal and 49.68 per cent by combined-cycle gas turbines. Combined-cycle gas turbine generation has to be maintained in order to cope with the intermittent nature of wind. The Campaign for the Protection of Rural Wales has denounced as futile the reliance upon intermittent energy sources because of this duplication of cost, because the average capacity factor of wind turbines is only 20 per cent. So, for 80 per cent of the time they’re not generating enough wind and, therefore, they have to be supplemented by other sources of generation, doubling the capital cost and also in the process, of course, emitting carbon dioxide emissions because of the energy intensive nature of what needs to be created through their capital costs.
