You couldn't get through the presidential debate on many channels without seeing a commercial featuring an electric plug getting its juice from a lump of coal.
The Sierra Club has helpfully put together a guide at coalisnottheanswer.org that challenges many of the assertions made in those coal industry ads, which the group says the industry spent $40 million to air.
The Sierra Club claims coal is neither clean, nor cheap, nor abundant, nor a good liquid fuel replacement for oil, nor is it needed at all.
Coal does power much of America's electric grid, but at increasing cost in dollars, and not without a heavy pollution toll. Emissions from coal plants are leading causes of smog, acid rain and the U.S. contribution to global warming. Promises of developing clean coal technology are still that promises.
This ad which you probably won't see aired as widely sums up the Sierra Club's argument:
