I'm a proponent of nuclear. But lets table that for a moment and talk about renewable.
If I were to propose a green new deal, this is part of what I propose:
Work with Electric Vehicle manufacturers and come up with a universal fast charging standard, like we have with USB connections on computers. Fast chargers are very expensive and there are basically 3 competing standards in the US between CHAdeMO (Chevy), Tesla, and CCS/SAE. It is a shame that these are not compatible with each other. The government spent a great deal of money on the interstate system, we could subsidize fast charging infrastructure.
Secondly, I would want all EVs to be equipped with an out port as well. If 10% of the population has a $15,000 battery sitting in their driveway, these could power 10 homes while solar isn't available. Charge by day, provide by night given that people run their dishwashers and laundry only when renewables are providing. It isn't as simple as having an outport, it would also require expensive equipment to transform and feed the grid but we could add that to new building codes for new houses.
I don't think people really understand the challenge of storage. Germany can provide 100% of non transportation energy when things are good, and 0% when things are not so good. Their main source of energy is coal and they are way more dependent on it than the US and environmentalists have nothing but praise for their system. We need to look to France, not Germany as a good example but if we aren't going nuclear, we need a crap load of energy storage capacity.
