This is also apples and oranges because unless you are both heating your homes the same way the numbers are irrelevant.
This is the only thing you said that I disagree with. If the comparison is being made that "A typical german household is not using half of an american but less then a fifth," then you are having to compare apples and oranges. The net energy usage (or, if you get right down to it, the carbon usage) is the point, rather than an irrelevancy.
The biggest factor of course is the price of electricity. There are market forces at work here. In the Pacific Northwest I pay about $.08/kw. I have barely any (financial) incentive to conserve. Add to that 90% of our power comes from hydro and I have very little guilt as well. Compare that with Germany where it is nearly $.40/kw. I'd probably be a lot more conservative if my electricity was 5x more expensive.
HVAC--for most areas--remains the largest consumer of residential electricity.
Like you, my electrical rate is $.105/kw. I live in a sunny area (far more so than Germany) but the mathematics for solar don't really make sense for me. Even with tax breaks my payback would be a decade out. Plus, most of my electricity is from the local nuclear plant and I likewise don't feel guilty at all (I've never been into self flagellation). I do more to conserve water as that can be (during droughts) more scarce.
