“In fact, it makes us wonder: just what have the other car manufacturers been doing all this time, if what amounts to an internet start-up company can suddenly come out with this.”

The item linked above reads in part: “Let’s not get bogged down in hypothetical meta-discussions about an electric car’s green credentials, because that way lies endless debates about how its ecological aspirations extend only as far as those of the power station it’s fed by.”
That statement is misleading. No, “endless debates”, about an, “electric car’s green credentials”, are justified. The issues are actually quite simple.
Pro: Any electric vehicle (EV) driver can provide for renewable electricity for that vehicle by generating green electricity with rooftop solar or entering into one of the many, “green power”, arrangements available around the world. All EV owners I know are doing one or both of these.
Con: But the EV driver can’t be sure that, in a mixed grid (part renewable, part fossil), that the green electricity paid for, is actually going into the EV.
Pro: Who uses a particular electron doesn’t matter. What does matter is the mix of renewable verses fossil electricity on the grid. If an EV driver pays for additional renewable energy to be generated, it will displace the same amount of fossil electricity, no matter where, or by whom, it is consumed.
Pro: Electric grids around the world are becoming cleaner. Worst case, if a driver takes no steps to provide green electricity for an EV, it will become progressively cleaner, as the grid it is charged on becomes cleaner.
