In a very good article over at the Telegraph, which repays reading in full, the tenacious Christopher Booker makes the point that the Government constantly talks about the capacity of wind farms to generate electricity, citing the total amount as if that's what they provide to the Grid, when - even on the Government's own figures - they only provide, on average, 27-28% of that capacity in reality. So all of their claims wildly overstate the abilities of the energy providers they're promoting.
The really outrageous thing about this is that Booker pointed out that the Government was doing this in a piece in the Telegraph on 13 September - and they just keep on doing it regardless. It is now a wilful untruth and it sits at the heart of our Government's energy policy.
This and things like it are behind widespread enviropower-scepticism which I increasingly share myself.
