An increase in efficiency does not necessarily mean a reduction in total consumption. https://en.wikipedia.org/wiki/Jevons_paradox

I've always struggled with the application of Jevon's paradox to decision making. Does it mean we shouldn't try to make our usage of scarce resources more efficient?

I think it just means you have to do more than simply make things efficient. You also have to have some way to minimize total costs.
