That's the same mindset that we've been holding all the way until now - since X is producing way more than we are, why stop? It certainly wouldn't hurt us to take a step back and reevaluate practices that could be changed - whatever they could be - in order to do our fair share of cutting down environmental issues.
People are increasing electricity consumption until: a. They can produce as much as they need. b. there is nothing too serious that would cause a significant climate change. Any local issues are not really affecting the global situation.
Now there is nothing that can make people stop and start producing less things.
