This would be a relatively major thing, since you generally have no choice but to breathe the air in your dwelling. As a policy matter (i.e., one in which the government can offset out-of-pocket costs for greater savings on the back end), subsidizing electrification so that Americans can have a better quality-of-life with less incidence of cancer, respiratory illness, and catastrophic detonation of inhabited residences seems like a no brainer.

And for people who must have their gas appliances, there are always portable units/generators. They can use those.
