In your textbook reading Chapter 26, the author suggests that an electric vehicle (EV) fleet can be used as a kind of distributed energy storage strategy. He assumes 1/3 of EVs might contribute 20% of their storage capacity to this scheme. The US has ~270 million registered vehicles. A recent paper has suggested that the US could generate ALL of its electricity from wind and solar, provided that there is 12 hours worth of storage for the whole country. The US generated 4,015 billion kWh in 2017, so an average 12-hr chunk of supply is 5.5 billion kWh. If we all drove EVs with batteries as in problem 3, could this distributed EV scheme provide the energy storage we require to live on just solar and wind? Show your calculaltions
