Martin:

And it is of course no support for your statement that the 'ecological movement' is addressing all the issues, as the current gov doesn't contain people I would count as part of that, while the previous gov did contain such people, and obviously did not deal with the house insulation issues in a way, that only small changes would be enough now.

You are really stretching it when you want to suggest that the greens did not want to do more in the Schröder cabinet than what was decided back then (the current programme, as DoDo states). Anyway, this is from their current (awfully titled) 'Energie 2.0 - Die Grünen Maßnahmen bis 2020'.
