I think it is political will and long term thinking.

Even today, aerial view of any place shows what a missed opportunity lies below. So many parking lots that could be covered ones with solar panels on their roofs(who invests on adding the panels? If I want to, would I be allowed to?) Same goes to the roofs of several businesses, supermarkets etc. It is not their core business to buy solar panels and invest for the longer term. Many times they are leased places, and the owner is some faceless corporate entity.

If a local politician thinks for the long term instead of what gets him/her elected the next term, they could change the city code to mandate opening up of such rooftops for community solar projects.

Secondly, the power grid needs to be strengthened/modernised to accommodate localised power generation. This ineens heavy investment.

Of course there will be the oil&gas companies that will fight every step of the way to keep the status quo because they are set to lose if people generate their own energy..

Actually the EU is thinking about exactly doing this.
