A libertarian will argue the government created these monopolies in the 1st place.
Sounds like you were busy proving the grand-parents point, and without any trace of irony.
It's enough that, had I the money to put solar on the roof (and if it was economically feasible - I have a small house), I wouldn't do it because I like the trees and don't want to remove them.
Oh I'm sure a free market will spring up to serve your needs in the future -- and people you identify with. If the trees have value -- which they do -- then some entrepreneur will figure out how to serve you. You should really be concerned with the average cost of energy, which everyone pays, regardless of the economic system. If the average cost is low, then the economy can only be good.
There are technological solutions to these types of issues, and some parts of the world are trying to develop the know-how. What we know about solar/wind, combined with long-standing trends, is that it is coming down in price fast. But moving to a new grid has inbuilt challenges, and some of the smartest people in the world are trying to figure out how to make the inevitable transition.
