Jo, they are saying that maybe wireless charge up may become possible in the near future, so no cables would be needed. How healthy that would be I've no idea.
Would the cost of electricity rise for everyone, regardless of whether they own an electric vehicle? Atm the government gets circa 70p in tax for every litre of petrol sold. They are going to want that money to keep rolling in. But electricity isn't like petrol, you can re-charge your electric vehicle at home; so in order to keep the quids coming in the government has to start taxing electricity, surely?
LPG. I have wondered why that hasn't become more popular. There are other options, such as adding ethanol to petrol, which makes the car run a bit cleaner and also the hydrogen fuel cell cars currently being developed by Toyota, Honda and Hyundai.
If what you say is true Suff there is no way we will be all electric by 2040. Governments going back for years have been kicking the can down down the road re building new power stations and they still are, as far as I can see.
