Sure, but right now, the only source of clean and abundant energy is fossil fuels. Everything else is either much more expensive up-front (hydro, nuclear) or is extremely variable (solar, wind). Nothing other than fossil fuels can travel well (electric cars are nice, but electric trucks are unlikely to be economical, and electric cargo bots are even worse).

So, the only current solution to climate change is global economic contraction - especially in the richest nations.
