Most people don't know it but street light were sold to public for improving safety on streets. The real reason was to provide night load for the boilers. Many boilers that run on low quality coal have small turndown ratio. If they need to at less than about 80-90% they have to use "stabilization" by oil or gas to keep the boiler from flame out.
What this country needs is high efficiency primary transmission network capable transferring energy long distances. There are several proposals in design and planning for DC lines. There are several in operation. Some already for about past 50 years. They are cheaper to build because they have only two wires. They can carry large amperage because they don't suffer skin effect. They have no capacitive or inductive losses. The biggest hurdle is converting DC to high voltage for transmission and back to low voltage for distribution to users.
If transmission and storage issues are solved then wind and solar could generate more than 30% of our power consumption. Then we could have large number of electric cars and have power for them.
Another thing about in example solar is that large portion of the investment is made by small investors by installing the equipment on their property. The problem for the utility is that they can't charge for the energy but pay for it. That is why they loobby hard to stop or limit PV. They would rather spend tax payer money and build another generating plant.
