I imagine it would look like some college campuses, with little electric vehicles hauling stuff about at low speeds, and most travel accomplished by foot or bicycle. Most people wouldn't own cars, they'd consider car ownership an expensive, unnecessary nuisance. Cars would be stowed away in parking structures on the outskirts of town, and renting or sharing a car would be easy.
Per capita use of energy would be greatly reduced because most people wouldn't often drive.
Energy storage is still a problem with solar, giving an edge to on-demand gas fired or hydroelectric central utilities, but we are getting nearer long lasting, less expensive, and easily recycled batteries. At the same time the amount of energy required for things like lighting, televisions, laundering clothing, keeping and cooking food, and computing is plummeting.
We are gradually replacing our compact fluorescent lights with LEDs. Both these technologies use less electricity than incandescent lights. Our new washing machine uses 1/4 the energy our old machine did, and it spins the clothes at very high speeds so they dry quicker. Aseptically packaged or dry foods can be cooked in the microwave oven and this uses far less energy than frozen foods and conventional ovens.
By some planning and good fortune my wife and I have avoided the commuter lifestyle since the mid- 'eighties. When we met we were both Los Angeles commuters. I don't miss the days it would take an hour to drive twenty miles, breathing carcinogens, and being on constant high alert for idiot, sleepy, and overly aggressive drivers.
