Elder daughter has an air exchange thingy - I'm never warm at her house and OH and I are often happy to leave in Winter and warm up in the car on the drive home. They do have a small stove, unused most of the year, but it comes into its own in very cold weather.
There is no gas in our village, so most people are on oil-fired boilers, but there are quite a few on wood heating (pellets), one or 2 have bottled gas. All this green initiative may be well enough for young people, but it's a killer for the old. Our house is very well insulated and as economical as it can be. We need to get fracking - using the experience of others to do it safely.
Asked the coal-man about his source for coal when he was delivering the other day (not to me, we don't have a fire or a stove, which is a worry) and he says most of it now comes from Russia! This seems to be lunacy to me. We have it and could dig it up, but are not allowed, so it is dug up elsewhere and then all the miles of travelling are added to its polluting effect. Barmy!
If heating does get as expensive as they think, then a lot of oldies will not be able to afford it and so will clog up the hospitals with chest ailments, hypothermia and other conditions. Well, it'll save on paying the pensions if they die, I suppose.
