It’s a 1:1 ratio. As I said I earn a credit, expressed as 1kWh, for solar produced in excess of used. I bank those credits over a rolling 12 month period.
It's not trivial, it's a heck of a lot of the great plains that are dotted with wind farms. Regardless though, the growth in renewables can only occur because natural gas peaker plants allow for the variable rate of renewable energy to be balanced to the grid electric demand.
I live in the Coteau Des Prairies in eastern South Dakota and there is wind out here. It really is a trivial amount of land in a typical farmfield and nobody cares that they can see the windmills off in the distance. There's not a whole lot to see out in the great plains anyways. It's miles of farmfields as far as the eye can see. The biggest hindrance towards more wind in this area was power transmission lines which they completed a couple years back.
