Just to add to the Kiwi picture of UK (and a large part of the rest of Europe I think) here, in a relatively rural part of Switzerland, but not up in the mountains (we're "flatlands", nearest sizeable town is about 8 Km away), we also have little choice for heating.
Electricity of course (if you're a millionaire, and not all Swiss are, I can assure you!) and oil. I have a nominal 5,500 Lts oil tank built into the fabric of the house (which was built in the 1960s, and also includes a nuclear fallout shelter - 'onest - and virtually all houses here have a cellar of some sort).
Wood pellets have become more popular over the last 10 years or so, but take a relatively large amount of storage space (more than the above tank needs), AND the prices are only now beginning to come down. Further, the admittedly small amount of smoke given off when the boiler first starts off does pong a bit - well my nearest neighbour's does anyway.
When we replaced our complete heating system about 15 years ago I looked into all the options, heat pump was FAR too expensive, electricity ditto, oil tank could not be converted to anything like LPG, and the nearest gas line was/is in the above town, about 8 Km away. And at the time the wood pellets thing was a new thing, and quite pricey, and the jury was still out re environmental benefits. Noting the comments above though, I THINK our wood pellets are produced in country, not imported.
Driving around here you will undoubtedly see lots of logs stored in lean-to shelters, but AFAIK, CH boilers to run those are few and far between these days (when looking for a new system 15 years ago we were told "old technology mate"), and mostly the logs are used only in "ornamental" single-room fireplaces.
So there are many here like me who have little realistic choice other than oil.
And all that makes our government policy even more annoying - even with the reduced oil price (I just filled up) I still had to pay an "environmental oil heating surcharge" of approx. 500 quid ON TOP of the standard (newly-reduced) price per litre! And the idiots KEEP saying they're going to ban oil heating here completely "soon".
Fine, in principle I've got nothing against that. But ONLY when I can replace my oil system with something of broadly similar efficiency and running costs.
As I just turned 75 the other day I'm NOT holding my breathe - and this BTW, in a country which, per comparable head of population and/or ground area, probably has more hydro electric production than anywhere else - I won't say "in the world", but certainly "in Europe". The reason why our electricity price is so high here is because we sell a lot to other countries, particularly since the next door Germans started closing down their nuclear power stations.
Like I say, give me a few more years and I guess how I heat our house will most probably be the least of my problems!
