"David JC MacKay", "Sustainable Energy"
There's a free book (Google it and you should fine it) by "David JC MacKay", titled "Sustainable Energy", from I think 2007.
He looks at how much energy we need, and what for, as a single country and as a global civilization.
Then looks at how much energy we could make from each type of renewable - both in theory (10% of the UK covered with wind turbines) and practice..
Conclusion is this : there are only two renewable sources which can provide country or civilization scale energy.
One is nuclear, the other is solar in deserts.
(And when we say solar, we mean installations 100km square).
The USA can do both, in the UK it's nuclear only, unless we want to put solar in North African deserts and trust those countries to be stable (and Tunisia, the only real hope there, is now heading back to dictatorship).
We need to replace more or less our entire energy generation plant with nuclear, and we need to do it, stat, NOW.
As an aside, carbon capture from the air is a complete white elephant.
The problem is you need energy to do it, you need a *lot* - country sized installations - and of course it need to be *renewable* energy.
It's a non-starter. We've failed now to replace our existing plant, which is not far from capacity, even remotely with renewables.
I recall we had to roughly double it for country-wide carbon capture.
This is not on the cards, which mean carbon capture is not on the cards.
Anyway, none of this is going to happen. Mass nuclear or mass renewables just is not going to occur in anything like the time frame needed.
As such, catastrophic climate change will occur, and by the time it's so bad people will bite the bullet, it will be about two or three decades too late.
We are stuffed, and many billions are going to starve and dehydrate to death.
