I'm beginning to think darkbeaver's location--currently given as "ward 13 special care"--might be true.
1 We've replaced all the windows in the house with triple glazed, argon-filled, high emittivity units.
2 We replaced the furnace with one of those 97% efficient ones.
3 As incandescent bulbs burn out, I replace them with low wattage flourescents.
4 We recycle papers, cans, bottles, plastics, and organic kitchen waste.
5 We bicycle a lot. Not today though, it's -18°C in blowing snow.
6 We walk a lot. We deliberately bought a home within easy walking distance of a major grocery store and a major mall. Conveniently, it also turned out to be within walking distance of a movie theater, lots of restaurants and coffee shops, a liquor store, a pharmacy, a post office, and a hardware store.
7 We drive as little as possible, about 6000 km in an average year.
8 We have low water use toilets.
9 I've installed flow-restricting shower heads in both bathrooms and we shower only once a month. We don't stink, because we're so pure of heart.
