Good to see acknowledgement that renewables don't work as they are intermittent and unreliable in terms of consistent supply. Bad to see a stupid argument that it can all be fixed by powering the grid from batteries in cars. Sooo stupid. Most people, well nearly all, will want their car charged so that they can use it. Why fill up a car and then sell the power? To profit? A tiny minority might do this, even buy multiple cars to make more profit. But 97% of people will want to use their cars for what they're designed for - travel.
