The environment-friendliness of an electric vehicle is only as good as where it gets its electricity from. By burning coal and natural gas to generate the electricity needed to power electric vehicles, we are just moving the emissions from the road to the power plant. The majority of the electricity comes from fossil fuels.
I basically agree with you.
On the other hand, note that in rainy states like Oregon where much of the electric power is generated hydroelectrically, it can be argued that electric cars are partly solar-powered since the sun’s energy moves water from the ocean to land in the form of rain clouds, rain water turning the turbines of generators. “Solar” states like Oregon ironically have a reputation for being overcast.
Based on the article referenced by this thread, however, we must now question if the latest electric car technology still falls short of the hype about electric cars being pushed by misguided environmentalists.
