I looked at those same numbers - and opted to use a power provider that uses 100% renewables. It cost maybe 5% more than our previous provider.

The key is consumers being able to select whichever provider they want to buy from. In my state (MA) that's possible because charges for energy generation and transmission are separated - but it doesn't work that way in many states.

That said, in places where the grid is substandard (i.e. Puerto Rico) there's a lot to be said for local solar generation and microgrids) - and a lot of the unused area available for placing panels is on the rooftops.
