In short, lots more than ordinary power generation:
The Telegraph has obtained a policy document, dated July, that seems to suggest that the government is considering a walk away from the most expensive renewables — and now we can see the full copy online. Two No 10 advisers challenge the Department of Energy and Climate Change’s utopian cost predictions, and say energy bills will be much bigger than we’ve been told.
What isn’t in contention is that energy itself will be much more expensive. DECC’s argument is that we’ll all start insulating our homes more — so our utility bills won’t reflect the higher per-unit energy costs. No 10’s energy expert thinks this is nonsense.
The Cameron advisors also suggest that government policy should be “open” to ditching some of the most expensive renewables — such as offshore wind power.
What’s the real cost of wind and solar?
The former power director of the National Grid, Colin Gibson, now estimates that the lifetime per unit cost of onshore wind is £178 per megawatt hour (MWh), and offshore wind at £254/MWh. Nuclear is £60/MWh. The figures DECC provides don’t account for the huge additional transmission costs of wind.
Note how much more expensive reality is than the clean, green vision. Government figures reckoned onshore wind cost £55/MWh and offshore wind £84/Mwh [. . .] compared to gas at £44/Mwh. Politicians seeking to dump the renewables policy could argue that green-minded civil servants sold them a pup. They’d be right.
