Roger, Wilco, Over And OUT

“Sustainable energy” just isn’t …. well, sustainable

” …We are hearing in the media that the cost of wind-generated electricity is coming down, and may reach parity with coal and nuclear (although not gas).

David Cameron, speaking on April 26th, reaffirmed his faith in renewables and called for prices to come down.  “I really believe that renewables can be among our cheapest energy sources in years, not decades”, he said.

I mean no disrespect to our Prime Minister, but the level of ignorance and complacency shown by his remarks is truly frightening.
Let’s get back to reality.
If you want wind to deliver, say, a megawatt, you need four megawatts of installed capacity (because the load factor is likely to be around 25%).  But you also need to build a megawatt of conventional back-up, either Wärtsilä’s internal combustion engines, or conventional gas.  You’ve paid the capital cost twice, for the same generating capacity.  (actually I make that at least FIVE times the capital cost, Roger! But, let’s be Conservative.)

But it gets worse… “

and then, as Roger points out, even at five times the cost of normal power it still doesn’t actually work as an alternative power scource –

” …(We also saw a graph that destroyed the myth of the Greens, that intermittency can be solved with a European super-grid because “over such a big area, the wind is always blowing somewhere”.  No it isn’t.  We saw a graph of aggregate wind output over a month in Spain plus Denmark plus Germany, which showed massive variation day-by-day and hour-by-hour, absolutely requiring back-up)…. “
