Add to that the USB-C 100 Watt and you wonder what else you need for low power.

BTW Frauenhofer in Germany proved feasibility of full sustainable energy supply. They also ran simulations usingvreal life data. Maybe it is because we have a pan-europese grid and one cannot compare that to a single state, like CA. https://www.umweltbundesamt.de/sites/default/files/medien/publikation/add/3997-0.pdf

As a matter of fact, currently already there is so much wind power in winter, when solar falls short, that a major power router and battery storage company (http://www.senec-ies.com) has a virtual 'negative power plant', which can sink free electricity distributed across the country by their sold units if there is an overproduction of wind energy. 900 or so seats left. No need to shut down wind turbines OR in times of peak consumption have excess spare gas power plants. Way to go!
But then, who would believe in a world with geo-political-free clean energy but the square pegs??
