I saw something ages ago about the world hitting peak power for lighting as LEDs took over. You probably won't increase the number of lights in your house and any LEDs outside will use minimal power, possibly solar. I think most people in the '1st' world have all the appliances they will use and won't necessarily get more cars. Moving the cars to electric should reduce emissions depending on types of generation. Of course companies want us to keep buying stuff and a lot of it (from China) is pretty cheap. We're stuck in a consumerism dependency.
'Net zero' may not be so easy, but we need to encourage more of a circular economy with easy routes to recycling. Old EV batteries can go for grid storage and eventual re-use of materials.
We need to be smarter. You have to hope 'AI' can help with that.
