Hey, look at me everybody, I have a certificate!
I had almost forgotten that a few years back I signed up to get a portion of my PECO electricity from wind power. The other day I received a mailing from PECOWIND patting me on the back and including a certificate that I could detach and, I guess, frame and hang on my wall. Look -- 2,400 Kilowatt-Hours from wind, however much that is!
In all seriousness, I do think it's a good idea for PECO to incentivize "good behavior," and the company has a right to crow that the U.S. Department of Energy named it one of the top five green power programs in the country. But dude, a certificate? Attached to a letter, both on heavy cardstock paper? That may or may not (no indication given) even be recycled? Seems like a little bit of dissonance there.
