Wood is very common in rural areas. Cold areas that don't have city gas largely rely on fuel oil (diesel), propane, and/or wood. Fuel oil and propane are both significantly more expensive than wood, even if you buy it pre-cut. If you have land and cut it yourself the biggest cost is time.
I know Finland has wood-fired electric power plants in the hundred-megawatt range. Just like a small coal plant but with a wood-fired burner. And while not wood, in a similar vein I believe Ireland was burning peat for electricity until recently.
While a lot of people have other heating/cooking systems, those chimney are still in use to some capacity.

My natural body temperature preference is to be too cold rather than too hot[0]. And people always have central heating on far too high for my comfort. When I'm in a building with central heating, I feel my face starting to flush and sweat prickling out on my back. It's horrible and makes me feel really uncomfortable. And because it's "central" heating, I have no option but to suffer.
With an open fire, on the other hand, everyone can regulate the temperature around them to their own comfort level : Too cold? Move closer to the fire. Too warm? Move further away. Central heating is the fascism of domestic temperature control!
[0] I realise I'm probably a rarity in this. I never have the heating on at all in my own home, even in winter. If I get a bit cold, I just stick a jersey on.
