  •  PV has some limitations (0+ / 0-)

    Available surface area limits how much PV in our most densely populated metro areas can generate. So even if it is a bit more expensive per kilowatt/hr, other options must be employed to support our urban and certain industrial centers.

      Sure, it can be put everywhere. It won't work well in the shade etc. But we have SOOOO many buildings in America alone that have flat rooftops.

      Consider a Home Depot. Those rooftops are 10,000 square meters. There are 3000 Home Depots! How about Lowes? How about Walmart? How about Target? Best Buy? Office Depot?

      I haven't bothered to calculate it all out, but I suspect big box stores could probably power our grid.

      Although being a non-profit, I'm inclined to try and help public schools fill their rooftops. We have roughly 100,000 public schools in America all with varying rooftops. I'd MUCH rather have our schools power the grid and reap the financial benefits.
