Cue much hand-wringing, consternation and questioning from government and the Society of Motor Manufacturers and Traders (SMMT), and what have they come up with.
Well:
EVs and hybrids are too expensive without subsidies and they will or have disappeared
The charging infrastructure is not there
There are too few models to choose from
They still do not have the range or fast charge needed for a lot of 'normal' users
They are not as 'green' as the hype would have us believe. See EU rules for 2021.
By and large they are a good idea and could wean us off the use of a lot of fossil fuel - provided the alternative is green power. However, they have fallen into the same chicken and egg problem as colour TVs. People hung on to their B&W sets until the colour TV service was up and running and proved to work before they went out and bought a new one. Another problem for EVs is the work being done on hydrogen powered vehicles.
The beauty of hydrogen, for some, is that current engines with just a few tweaks will run perfectly well on it. So, no big tooling up or new plants for manufacturers. They could be filled up at 'traditional' type filling stations, so they need very little new infrastructure.
However, current methods of producing hydrogen, mainly from water, are expensive and not very green. Crack those nuts and hydrogen looks like a win-win for us all.
