Electric cars run on coal

The essay by Randy Salzman [January 26: "Dumb and dumber: Silly stuff that's supposed to be green"] was well-written and covered many important points. I truly applaud the author. However, it failed to mention the most glaring fault of electric cars, which is that electric cars do not actually run on electricity. They primarily run on coal.
