WSJ; Overheard On Wall Street: Super Bowl's Marketing Play-By-Play Power Off

"The game's partial black-off offered a glimpse of what it would be like if coal-fired power plants were shut down." Coal miner Peabody Energy issued the statement on Monday morning after the big game.
True, coal is important. It fueled 37% of U.S. power in the 12 months ended in November. But the juxtaposition with Sunday's blackout is somewhat strained. For starters, it is unclear what caused the lights to go out. Some have blamed Beyonce's intense halftime show. Utility Energy's announcements seem to indicate a problem at the stadium itself rather than lack of power per se.

And even if it were a supply issue, the vast majority of the power in Entergy's New Orleans unit comes from nuclear or gas-fired plants, according to data from mid-2011. Indeed, this gets to one of the reasons why coal needs all the promotion it can get. It is losing market share to cheap gas, which provides 30% of the country's power, up from just a fifth five years ago.
