You accused me of trolling when I said that I believe people are good in general and that you shouldn't force them to do anything. I think you shouldn't be surprised if that comes across as an offense.
> Most people care somehow but not enough at all to risk anything. They are even afraid of 'new technology'.
You need to make it attractive for people. Think about the risk/reward here. People are not dumb. They know that investing into new technology comes with a risk per se from experience. They also know that their investment has a slim chance of doing anything to reduce global CO2 emissions because many other factors are at play here. Then, it's not even clear how much of that makes for the current warming. So you need to give them something which is an obvious benefit with regard to their current life situation. If you have access to charging at home, solar panels, and an EV, that's a financial benefit that doesn't need much more explaining. Now you need to find a way to make that accessible to everyone. Better charging infrastructure, increasing range, and bringing down the cost of the technology is key and it takes time.
