How do I deal with expertise in energy waste that no one values?

You can walk into almost any building and see where it bleeds energy, waste that is invisible to everyone around you. That is a rare and real skill, and the resentment you feel at how unseen it is comes from knowing exactly how much it is worth and watching others miss it. The frustration is fair. But consider why the expertise looks invisible. Waste that gets fixed leaves no trace, no drama, just lower bills and steadier buildings that people quietly take for granted. Your work hides inside things that simply do not go wrong. That is not the same as being worthless. It is the particular loneliness of prevention, and prevention has always been undervalued because absence is hard to applaud. So make the invisible visible. Put a number on the waste you see, in dollars and in carbon, and show it plainly to the people who pay the bills. Do not expect them to notice on their own. When you translate your sight into money and consequence, the expertise stops being invisible, because you have given people a way to finally see it too.
