Yes, everybody knows that EVs received precisely zero government subsidy in terms of R&D, business loans, and consumer rebates. That free market did it all by itself. And we've got what... 1% of the cars on the road running on electric?
Take those away and the "green" companies would have NO incentive to push their work. They'd be working with people wanting to do better first and foremost, and then they would - ironically - be competing with petrol and energy companies, who also have "green" all over their marketing.
Renewables and EVs could not compete without government incentives.
Of course, that is the ideal success scenario, in the failure scenario, you subsidize the thing until it fails, or until you can no longer afford to subsidize it.
EDIT: grammar
1. Tesla's impact on global emissions is minimal.
2. Government intervention in EVs has been there from the start.
The charitable conclusion is that governments and markets can work together. The pessimistic conclusion is that markets are only capable of putting lipstick on pigs.
Science, Capitalism and entrepreneurship will be the unstoppable force that will solve our energy crisis, if western governments let them.
Africa, India and China will be the biggest factors going forward.
UPDATE: To be clear, I'm not arguing for laissez-faire capitalism. Government incentives are required to develop markets, as Germany did with PV, and US does with EV. My point is that the US being part of the Climate Accord or not won't matter much, the move away from coal and ICE cars is inevitable due to already existing market forces. A bigger lever would be to de-regulate nuclear where it makes sense, as that is where the biggest cost lie.
