It is a misleading (at best) term, referring to the fact that the national
power grid includes input from coal-fired power plants, therefore
incorrectly implying that everything powered from the grid is primarily
powered by coal.  (Granted, coal, natural gas, and petroleum - in
other words, all fossil fuels combined - are over 50%, but that's at least
not just coal.)

This also overlooks the radical differences in efficiency and environmental
effect between large power plants whose emissions can (at least in theory)
be captured and stored (as opposed to being released into city or
wilderness areas), versus lots of small internal combustion engines that
have no practical choice but to dump their emissions at the point of use
(along the roads that go right through populated areas).
