This is a common problem with regulatory agencies. They're created to address some real problem, but then they address it, and they still exist, so what are they supposed to do now?

Meanwhile the original rules were the low-hanging fruit. Originally some products were only 50% efficient, but the modern products are 90% efficient. Energy consumption fell from 300 W to 167 W. If you ask them to trim off another 133 watts, that's a violation of the laws of physics. If you ask them for the last 17 watts that are theoretically physically possible, that's not really a thing either. At best you can trim off another 5 W by making some onerous design trade offs that aren't worth five watts.

But what are they going to do if their job is to make new rules?
