Changes will only happen when they can be monetised. Do we really think shipping parts all around the world to build EVs and then charging them, dealing with batteries, etc, is better for the environment than using different fuels for combustion engines? EVs are very profitable - even charging stations represent a huge margin for the providers now that they've done away with the initial rates. It's nice to see Porsche investing in this. There was an interesting video on Harry's Garage showing engines producing water. That seems far better than EV.
Turning amps off might make people feel good and save some pennies but there are far greater issues to deal with and turning those amps off isn't going to save the planet in my opinion. Not that climate change is something that can be entirely avoided anyway. Sure, it all adds up, but these things compared to the other issues and ever increasing populations, requirements for food, etc, are of far greater significance.
