Personally, I think when the world realises that most electricity is generated by burning fossil based fuels (which in the UK’s case is brought in by dirty oil burning ships) there will be a swing away from electric vehicles. Wind/solar in this country cannot provide ‘base load’ generation (our climate negates against it). Nuclear which can provide a healthy base load is too expensive, leaving burning natural gas the largest source along with burning Biomass (wood pellets brought from the USA in ships). Neither is exactly clean emissions wise. Plus both must be imported nowadays as the North Sea is vertually empty of natural gas.
People often think electricity is ‘clean’ but neglect to look further up the food chain to see how much CO2 etc is emitted during generation and delivery of the source product.
Also the environmental and health concerns about the process of extracting the heavy metals (usually in poorer countries) for batteries from ore mined underground are going to raise their heads as well.
In time Electric/Battery propelled vehicles will become the ‘Betamax’ of the vehicle industry (for those under 40, I recommend googling ‘Betamax’).
Pretty much the same as is what is happening with Hybrids now. Much rush and bluster about them, but no longer needed in the long run.
In the longer term once Hydrogen infrastructure is more widespread it is the only way to go.
