Energy companies see rooftop solar as competition. Their primary motivation is profit. I do not doubt that they will all eventually go 100% renewable, it's just a matter of ensuring that they lock in their profits. Another issue is the amount they can charge customers. The utilities are also charging for maintenance of the power lines. With rooftop solar, that fee is lost unless the home owner pays the monthly fee to tie their system to the grid.
