I appreciate your willingness to share the environmentals of your present living situation with hints regarding your choices given the day's conditions.
I'll skip over an enumeration of the locales I've lived were the seasonal conditions varied from one extreme to the other.
The point of my point was to highlight 2 factors germane to maggie's post. The first is that power shortages result from strain the electrical grid must endure when demand/supply mismatches become acute. The second point was to tie-in maggie's book on the subject which is IMO a bright-light of insights and pragmatic thinking about the issues of AGW, civic infrastructure and the obstacles to a viable, sustainable solution.
If you've not read magggie's book, I can't recommend it highly enough.
