Are governments hoping they can actually create enough energy to power
Yes they think so but based on a wrong look at implementing,
The Big problem is that goverments don't realise the cause and effect of EROEI when there is a declining amount of oil. They only think in terms of money and megawatt per hour to implement renewables which at this moment is the limiting factor because we have plenty of oil. But in the future the amount of oil and eroei of renewables will be the limiting factor.
The govermental approach is starting to get a bit of rush now, there is an energy conference by one of the more "leftwing" Parties from the dutch goverment (opposing site) this saturday about nuclear stuff which is quite a stuck debate here to use it or not. Has been so for a while. this is like the first thing in a long time i have seen.
