Renewable energy tends to work at a household scale. If you can produce enough electricity for your home, why connect to the grid? Some see a vast move of people disconnecting from the grid for cost and independence. That will be true for many, but for many more they may stay connected to handle peak loads, be able to sell back to the grid, or as a backup. The dynamic is large enough in either case that public utilities must begin preparing for a dramatic shift in their service. Recently, they provided all the power, and delivered it through the grid. As more houses can produce power, the utility may provide the grid and only add power when necessary. They may even have to provide incentives to keep people tied to the grid. If not, electrical lines to houses may go the way of landline telephones.
