switching to gas electricity
Gas is a fossil fuel too.
Go nuclear.
Re big vehicles, we need big vans to carry 4 people and a pile of equipment. A piddly electric skate cannot do the job. And sometimes the van has to be used to get to the shops. Which are much more than 1 km away. Only when I lived in Sydney was there a supermarket within 1 km. Not in (at the time) Point Cook, Bullsbrook, Farrer, Ipswich, Raymond Terrace, or Ellerston (1 hour drive to a shop). You have been able to choose your locations well. I have not been so fortunate.
Our personal vehicle is a 7-seat SUV, because (a) I like it, and (b) we often carry a tribe of people 140km to Brisbane and back. There is only 1 train per hour to Brisbane in daylight, and the station is 40 minutes drive away. Or a 90-minute bus ride away, with 2 changes of bus. Only practical to burn some dinosaurs and drive.
