And you'd combine the two to make sure all of the wind energy gets put into a car battery, or car batteries don't end up full because the owners don't need it tomorrow and the wind is expected to be strong tomorrow evening. You can do the same solar energy and cars plugged in during the daytime, soaking up excess solar electric generation.
