A quick Giggle shows that we use 49 billyun litres of fuel a year for transport needs. If we change to electric vehicles, this will need to be replaced by power stations. 49 billyun litres a year is around 5.6 million litres/hour. A litre of petrol/diesel is about 10 units of electricity, so we're talking about 56 million units/hour. IOW, we're talking about 56GW of grid capacity IN ADDITION to what we have now.
1) Any one care to query that?2) Where's it gonna come from?
