This is not something that should be done lightly. If your problem is that less waste heat is escaping the system, reducing the energy entering the system is not a 1-to-1 solution. His first attempt was too small to have any effect, and maybe he intends to continue operating at a small scale where he's just uselessly grifting, but if not he'd be unilaterally sabotaging the plant growth and solar power that relies on that incoming energy.
