I think he’s referring to the somewhat misleading idea that all electricity is “clean” energy. And the fact that they are really hyping that up in this video. There’s conflicting “truths” out there about the true environmental impact differences between EV’s and ICE vehicles. Not only do you have the production of the electricity itself, you also have to think about the battery production / recycling / disposal aspect as well. Environmental impact is not my main reason for driving an EV. I like the performance, I like the leading edge tech that Tesla was bold enough to put out such as autopilot, and I like the fact that there’s minimal routine maintenance (other than tires and wiper blades/fluid). The fact that electricity can be cleaner is a bonus.
