How do you heat your dwellings? 
(I know that your houses are usually better built than the ones in the USA, but I still have the impression that you waste a lot of energy, to be honest.)
		
		
	 
I have learnt that people in other countries are often less comfortable in their homes, because heating is only available/customary in certain seasons, and because heating is often accomplished with appliances used "as needed" when a room is chilly.
The method of heating may vary in Canada (the Prairies use natural gas, usually for a forced hot-air furnace, occasionally for hot water radiators, electric baseboard heat or natural gas in BC, and I understand down east they still may be using tanks of oil delivered to the home (which stopped in western canada in the 1960's I think) but whatever the method, it is integrated into the home. The furnace comes on for heat as easily as the tap comes on for water.  
The house is 
always 20.5° (or 23 perhaps, if you're a "woman who wears sweaters").  When it is -37° and howling with wind outside. But it's the same when it is +17°, and it surprised me to discover people in other countries might just tolerate it with an extra blanket or a thicker shirt. Unimaginable here. I remember the news: they shot Ceausescu for making everyone keep their thermostats at 15° to save enough energy for his palace...
In our climate, heating is definitely the biggest user of energy.  In some areas, so is cooling in the summer. It is desirable in the southern prairies. Necessary in southern Manitoba and down east - I think Toronto would be uninhabitable without air conditioning.
The large size of the country is maybe the next biggest user of energy.  Our biggest cities (Vancouver, Montreal, Toronto) are being squeezed into more European dimensions. But most Canadians live in detached houses.  Our cities are as big as a European capital, but with a tenth the population.
Metro Edmonton: 9500 km[SUP]2[/SUP], population 1.1 million.
Metro London, UK: 8400 km[SUP]2[/SUP], population 14 million.
So far they are unwilling to build proper transit systems for cities with that much space. So we drive everywhere. In the winter, over streets rutted with snow and ice, meaning people prefer a bigger car better able to handle the roads.  This uses energy too.
Within the home, though, I think we are just as likely to use energy efficient light bulbs or use timers to efficiently control their use, etc.  And our homes are superbly insulated.
It will also get better. Most of the world is preoccupied with saving energy in high-density cities in temperate climates.  The solutions that also work in our climate have all already been implemented.  We will develop different new solutions that work here as well.

Incidentally I have no idea how you Europeans manage in cities so crowded. I can't imagine the equivalent of sharing my property with 10 other families. GAH!
