I don't think it is possible to at the same time develop nuclear energy (that is brag about non-polluting-too-cheap-too-meter-our-new program-will-also-be-called-'ploughshares' electricity) and tell people that they have to spend X euros insulating theirs houses, buying special light bulbs, etc.
To me the discourses go in opposite directions. Rien n'est gratuit en ce bas monde. Tout s'expie, le bien comme le mal, se paie tot ou tard. Le bien c'est beaucoup plus cher, forcement. Celine
What is needed is closing fossil power plants and replacing them with something else, and that something is very often nuclear.
I see no inherent problem in promoting both nuclear power and improved efficiency.
It can be framed like this: "our power use shall be efficient and our power generation clean and competitive". Peak oil is not an energy crisis. It is a liquid fuel crisis.
