If everyone shifts to EVs and Vehicle to Grid becomes a normal thing then securing the grid would be a solved problem. Most cars spend more than 90% of the time standing still. If every parking space was fitted with a mid-range, say 7 KW charging point that would go a long way to providing sufficient grid storage.

My Tesla S 70D could supply my house for at least 24 hours if it had V2G.

To secure the grid in a zero-carbon world, we need to supply 4-5x as much electricity and be able to run without renewable generation for over a week.
