The Jevons paradox probably applies the strongest to energy, actually. Even if the typical home consumer isn't responsive to energy efficiency, energy is highly fungible, and, at any given moment, there will be many industrial projects just "waiting in the wings" for a tiny change in energy prices to flip back into profitability.

So, in the absence of coordinated legal restrictions on emissions, the most likely effect of your personal cutbacks is for someone else to ramp up. Sad, but true.
