Yes I think this is the reason. At least for our class of life: organic. Organic life naturally evolved & so all intelligent organic life lives on top of a pile of stored chemical energy (oil / coal / methane gas) Organic life evolves through competition and so when chemical energy is discovered it is rapidly used, most often faster than such intelligent life can figure out what a truly bad idea that is. Once they realize, it's too late. Runaway climate change is occurring. And this ends the intelligent life.
