Your examples aren't well thought out. Solar panels can't provide electricity at night, so you still need a network (for the time being - hopefully batteries change this sometime soon). Most properties don't have wells, especially in the cities, so you'll always need a functional water network. Networks result in natural monopolies, unless correctly controlled/legislated.
