In Norway more than 50% of all new cars are electric. They are heavily subsidised, but it proves that it is only an economic question. I was born in the seventies. My next car will be electric. The only reason I’m holding of is that there’s no model that fit our needs yet (except an very expensive Tesla), but I expect that to change within two years.

For industrial heat they will use hydrogen produced from renewable electricity. See for example [0] where it will be used for large scale steel production.

All the technical and economical components for the shift are already in place. The only thing lacking is political will (and apparently knowledge).
