Nuclear has significant carbon costs during construction, fuelling and clean-up - unless uranium fuel is mined on-site. So pretending that nuclear is carbon-free is just plain wrong.
Renewables also have a carbon cost, for similar reasons, but obviously it's a very much smaller one.
It also would have been interesting to see what X thousand windmills or Y nuclear power stations would have meant for the UK's available development space.
And microgeneration could have had a mention too.
(And so on.)
