Does it do a paper round?
Pay Per Round? Pay Per Play?
No...
My setup is power hungry (plasma TV - 200+ watts - and Krell - 280 Watts idling), and makes heat (more air conditioning expense), so I looked at Solar briefly, decided it is a big illiquid investment with a long pay-back period at which time the system lifespan is likely over and would need major refurbishments, so I parked roughly the same amount of money in the local utility (TECO) stock, 5% dividends paid the entire electric bill right away (well, quarterly), then the Utility was bought out by Canadians (Emera), and I got a surprise capital gain of a little over $20,000, which covers a lot of my past gear purchases.
Moved some of that money to Emera Stock for their dividends to pay the bill, but found I have to pay Foreign Tax on the dividends, so, may rethink that little strategy. Currently have a little gain on that investment (plus dividends to pay the electric bill).

So, in my mind, because the system is inefficient, I decided to hedge the operating expense, and got lucky on that exposure.
Therefore, this system paid for itself (and then some).
Estimate of the split between general electrical use and the Air Conditioning in watt hours per day (by week) for the last year:
Seven years coal-fired (and they have some gas turbines now, too, and are building solar farms) electrical usage:
Ok, I'm warming the Earth, just doing my part... On the other hand, I don't drive much, so, maybe I'm more green than average.
