### Comment:
As someone who has solar panels I can tell you they are not a primary energy source. I still use natural gas. Solar is great for supplemental energy. But basic physics and math shows it's nowhere near as efficient.

### REPLY:
First Solar is utility scale only and the economics of that are changing pretty rapidly, it is already far superior to rooftop panels which struggle to be economic due to the cost of installation. It's a lot easier to line them up in a field and string them together than it is to put them on a roof and wire them into the grid
