Coal powers us

The commentary in Tuesday's Post-Gazette by Robert F. Kennedy Jr. about the burning of dirty coal is obnoxious ("Coal Cannot Be Clean," Sept. 22 Perspectives). What a hypocrite.

He was surely using coal-fired electricity when he used the computer at his home or office to write the article. Also I guess he was writing in the dark, or did he dare use coal-fired electricity to see what he was writing?

As he was preparing his convoluted article, he and his family surely weren't using the washer, dryer, microwave, refrigerator, toaster, outside lights, etc. And I mean etc.
