Electric cars are getting cooler, maybe they will stick this time around?
As Daan mentioned electricity demand to recharge cars may require significant investments to produce additional electricity, and distribute it.
Another limiting factor is battery technology which has made huge leaps in the past two decades, but also requires huge amounts of energy to mine and refine the raw materials.
I get that people feel green when driving an electric car "to save the planet", but it is simply shifting the extraction and refining of fossil fuels for another list of materials to use for batteries, solar panels, and related components.
Energy is not free, and converting, and transporting energy leads to losses at every stage.
Until we obtain the Holy Grail of free energy, we are not focusing on the right problem. The larger issue is simply how much energy is used and wasted by much of the Earth's population, which in turn continues to grow due to the abundance of inexpensive energy.
There is a really great comic by Stuart Mcmillan about energy, Bukminster Fuller, energy slaves, peak energy, and conservation: check it out:
