I don't know about the US, but here in Europe there are huge numbers of small wind and solar installations going up on residential and commercial property. Architects and energy experts are calling it "eco-bling" - largely useless, but a highly visible and expensive way of signalling how much you care for the environment. I've lost count of the number of solar panels I've seen fitted on the north side of a building so as to face the main entrance rather than the sun.
