Being sort in the middle here in Canada, with a harsher climate and
one tenth the population of the USA in a larger country, will add the

Electricity, produced almost 100% by less polluting hydro (water)
power in this part of the country is reasonably priced. Domestically
homes here use electrical heating almost entirely. Especially new
construction and renovations.
Also since electrcity is used to heat hot water, if when that water
cools down in the pipe or gradually over a two week period escapes
from extremely well insulated hot water tanks it contributes to
heating the home!
If the hot water was turned off the electric heaters would have to run
just a little bit longer. All electricity entering the house ends up
as heat! So it doesn't matter how that electricity is turned into
heat; by inefficient light bulbs, electric heaters or via hot
water ............ in fact some use electric hot water 'furnaces' in
some cases replacing 50 year old, hot air or hot water, oil furnaces
or for warm water underfloor heating.

I can remember the dirt, smogs and pollution of the 1940s and 50s in
the UK when we still burned coal! Acid rain! The rain off the roof in
Liverpool, for example, was black!
