I've spoken to David TC Davies on a few occasions, and I have to say that he's a rather pleasant and affable person face to face ... the problem is that quite a lot of what he says in public is stark raving bonkers.
He's just provided us with another example in this article in the Western Mail:
Apparently, we are being asked to believe that:
Official statistics show that by August 2013, the amount of renewable energy produced in Wales was already running at 9.7 TWh.
The official figures for electricity generation are published by DECC, and are available from this page.
The figure for the whole of 2013 was in fact 2.664 TWh ... less than a third of what David Davies quotes.
Now it might just be that he is thinking of the total energy, rather than just electricity, produced from renewable sources. But he probably isn't, for two reasons. First, the figure of 7 TWh/y he quotes comes from paragraph 1.4 of TAN 8, and is specifically for renewable electricity. And second, because the DECC tends to measure total energy in TOE (tonnes of oil equivalent) and as we can see from table 6.6 of these figures, over 70% of energy from renewable sources is used to generate electricity. Therefore even if he tried to claim that he was talking about total energy, rather than just electricity, he'd still be talking complete rubbish.
So, to be clear, we in Wales have definitely not "exceeded" our renewable targets. Paragraph 1.4 of TAN 8 sets two of them: 4 TWh/y of electricity from renewables by 2010, and 7 TWh/y of electricity from renewables by 2020. In 2013 we produced less than 2.7 TWh, in other words we were still a long way short of the 2010 target.
In fact, the picture is quite bleak, because the two large offshore windfarms that would have significantly boosted the amount of renewable electricity generated in Wales—the Atlantic Array in the Bristol Channel and the Celtic Array in the Irish Sea—have both been cancelled.
