Climate Change

[IT Minion]

Looks like a load of hot air to me. Where do you dredge this rubbish up from?

It's a really good book, I read it when it was first published. But it is very dated now, as that was in 2008. Some of the numbers are funny in retrospect.

Back then industrial PV farms cost around £4,000 per kW capacity. Now you can get (much more expensive) roof mounted PV for around £1,000 per kW. Even if you need to build new grid connections PV farms are lower than that. And the idea we could get nuclear power at £1,300 per kW is sadly nonsense, it's more like £7,000.

It is a great introduction to the practicalities of going to a net zero society, even if the mixes proposed then don't hold up to modern economics.

I suspect that somebody works in the solar panel business!

PV, which only works, when the sun shines. I notice that when we most need the power, in the winter, that the sun just don't shine that long, nor that bright. Nuclear, can run 24/7, winter and summer, and is not reliant on good weather to work.

Nuclear runs at around 80% capacity and you have to buy it even when you don't want it, at a ridiculous price.

Wind is higher in winter, lower in summer which balances out PV for the most part.

You really didn't read the book did you? It covers this.

Really - I think you mean 'wind can be higher. Much of the time, and for many weeks, in winter, there can be periods of zero wind - none at all, and no sun. Then what?

Today, for instance - dark, almost no wind, and the energy cost is at a recent very high cost. That, is a good indication that so called renewable, just are not coping. Instead, we are burning gas, to cope with the Sunday load.

Wind is currently delivering 32% of the national demand. It was around 40% for most of the day.

It's almost like there is more weather in the UK than just around your house.

And the rest, from fossil fuels!
