While most energy sources have risks, those from fossil fuels are well known and society has devised ways of dealing with them, that are now embodied in the institutions, such a fire fighting. But there are new dimensions of problems with the batteries of electric vehicles, and these problems need to be completely solved before any transition to electric vehicles from normal fossil fuelled vehicles is made, but it is not going to be done in the frantic rush to be “Green.”
Electric cars can spontaneously combust, and there have been many cases of vehicles doing just this. Most major vehicle producers have recalled sets of their vehicles at one point or another because of features discovered that could make this fire risk greater. While the present number of such EV fires is not greater than the number of vehicle fires from conventional sources, the EV fires can occur in garages overnight. The fires are extremely difficult to put out, and even if it seems they have been extinguished, may light up again. This self-ignition problem is also seen in grid-scale batteries associated with wind and solar power, and these fires are even worse.
