Not on the right order of magnitude. We need to reduce our material consumption and energy consumption, even keeping them to the present level would not be sufficient, so for what you're talking about we'd need absolute decoupling, and that won't happen through efficiency gains, I'm willing to take that bet any day (and without even invoking Jeavons' paradox). https://eeb.org/decoupling-debunked1/ PS: this was this week's latest paper that helps comprehend what exponential growth means: https://www.nature.com/articles/s41586-020-3010-5
