This[0] shows that coal fueled energy production produces about 65% of CO2 emissions related to energy production in the US. This[1] shows that energy production makes up 92.6% of all coal consumption in the US and residential is at most 1% of that, so it's pretty insignificant in CO2 emissions compared to the other sources of energy production, namely natural gas which produces 33% of all CO2 emissions related to energy production. However, like you say, it'd be significant in places where coal heated homes are more common. And the other pollutants that cause smog and acid rain and other issues definitely cause local problems. But emissions caused by energy production are a much larger problem on a nation wide scale.
