It changes things. Europe is developed. If Europe and other developed groups don't switch to clean energy, transportation, heating, etc, the future industrializing countries with probably 2-3-4 billion people will fry us all.

It's not a moral imperative, it's simple survival.

Ok, now try to sell an electric car to someone who makes 10K/y or less.

People just won't have cars.

Hey, I'm not from a developed country. Poor people will just buy second hand cars from developed countries, give it 5-10 years.

They'll just need beat up Opels with 300k km on them :-D

That's pretty difficult, unless fixing batteries for dirt cheap (and with enough range to inter-city travel at least) becomes doable.

I can't see someone making any useful of a VW ID3 in, say, Morocco.
