Nuclear is a high risk game. The evidence is there. Just look at what happened to Nuclear Electric and British Energy. Even recently the combination of Magnox North and South to increase nuclear professionalism and best practise. Private investment is key for a nuclear success.
I'm not sure it is key personally, what is key is that the investment is sufficient and that the things are well run and managed.
But as you know from my previous postings on the topic, I want to see 50-50 private/public partnerships for the things anyway (and only if no private backing can be found then 100% government venture selling off a stake later down the line)
I agree. However from reading your posts, you expect nuclear to happen overnight.
I don't expect things to happen overnight, but after 13 years of "good times" I would have expected to have several builds under construction already with far more planned.
I expect us to have a building boom similar to what China is doing, to future proof our power generation.
I'm afraid it's not. Just look at ErDF, they are struggling with rolling out charging points - even on a small scale.
One of the problems they had (initially) was planning permissions and places to locate the charging stations.
Secondly the cars are only just arriving (a slower start than some other countries mainly due to the fact that we only have one "home" automaker with an interest, BMW with the MINI).
However, we all know that the future is battery electric, so government needs to step in and ensure that infrastructure is build
You're naive. It takes a good few years to field test and tweak discoveries.
Yes it does, but we are over 8 years away from 2020 ... so even if the new cars are not out by 2015 with the tweaked technology - that leaves 5 years to replace 50% of cars. It all depends on price and how economy is doing.

That's what I am saying.
I know you were, but I fail to see any justification for why 80% is too much.
With increased demand at night to charge things it could well see the "base" use rise to 80% of maximum.
