Most of all, just thinking about how even renewable energy is entirely embedded in our process of transforming raw resources into waste (with a little bit of economic value extracted in the middle)... This is really just the second law of thermodynamics making its presence felt (not to imply that we're anywhere near close to some kind of entropic limit in the construction of wind turbines, but as a rule of thumb: in the process of doing useful work, things degrade).
