I'm coming to the same conclusion. I don't pay near that much in electricity annually - less than a third of that - so, yeah probably not worth the bother.Based on some experience, I'd tell you it's probably not worth it. The math just doesn't work out - if you are paying $3500/year for electricity (which is YIKES high, even in the central valley) and can justify 2% of the usage is because of band practices (which is a bit high - that's 3.5 hours of your total weekly usage) and you're looking at $70.
I guess the answer to my question "Does anybody do this?" is mostly "No".
Thanks all.
