I agree with you on ag and chemicals (many of which we would be better off without), but wind and solar are making rapid advances and lower costs, thanks largely to China. So are batteries and other storage devices. Those prices will drop as the market expands. Speaking of efficiency, an EV costs about half per mile compared to an equivalent gasoline vehicle. This conversion to electric vehicles may come sooner than most people expect.

Given continued economic growth, I see the market for internal combustion engines shrinking, first slowly, then rapidly. The military will want to carry liquid fuel with them, however.
