Solar really seems like it's taking on a mind of its own & while it would be nice to get help from the US gov, it doesn't seem to need it.
It could be that I'm overly optimistic but new energy installation will have to grapple with the fact that solar is cheaper, & regardless of loyalty to fossil fuels, businesses will always go with the cheaper option.
I think you're exactly right, now that solar is cheaper than fossil fuels, market dynamics dictate that it ends up being used because it makes companies more competitive.
