yes, this is the problem. we use more energy in transport than we do electricity, so we have to generate an awful lot more electric (and to replace gas remember). fast charging makes adds complications as more current is needed, so you cant just plug into the normal mains.
Eons response is from the marketing department writen by BA graduates, engineers will know that we dont (cant) produce enough energy domestically. people will say you can do with solar and battery systems, but it doesnt scale out to the whole population. home generation could be a thing if we went down the hydrogen fuel cell route, but no interest seems to be shown in that.
I am no expert of the technical elements of this but as I understand it the battery technology is key to this, the latest rapid chargers that are being rolled out deliver the charge from huge battery packs and not directly from the grid.
The answer to mass adoption of EV's is also not necessarily about increasing overall capacity of the grid to produce more electricity but smoothing out fluctuations and peaks in demand. For example they are current trialling vehicle to grid technology where EV's communicate with the power grid and respond to fluctuations in demand by either returning electricity to the grid or by throttling their charging rate. In this way EVs could be used to solve some of the problems with renewables as they will be able to store the energy when renewables such as wind and solar are available and then discharge it back to the grid when it is most needed. In addition to this it seems likely that all houses and businesses in the future will have there own energy storage facilities/ batteries which will also improve the overall stability of the grid.
