At least in the UK, using coal or oil is very uncommon, while gas is very common.

So gas is the bigger problem to resolve. We need to get rid of them all eventually.

Totally agreed! But for me I'd love to strike the word "eventually" from the sentence. At this point we're in such deep shit that we have to move more quickly than "eventually" in my opinion. :)

It's far better to emit NO pollutants in your home (and cars!) than to emit less, especially since polluting home infrastructure is replaced every ~15 years and pollutes for its entire lifetime.
