A funny thing my power electronics TA pointed out at a lab class was that, while incandescents radiate heat and waste a lot of power to just heat the space below them, we still need to heat our classrooms. When the university went from incandescent to fluorescent and, later LED lighting, the only thing that changed was the power usage shifting from lighting to heating. Granted, heating can be more efficient when handled by the systems designed to heat, not to illuminate, but at the scale of a reasonably big, cold-war era building with moderately inappropriate insulation, the gain in efficiency is minuscule. It all made me think that we're solving a lot of problems by shifting the issue away from us, in this case from the bulbs to the radiators. It's comparable to EVs in my opinion: "if we take all the pollution and put it in SE Asia, we can cargo cult ourselves into thinking that driving that 20yo beater is worse than generating new waste"
