against a 50 Watt monitor, running 24/7, this would save you 100€ per year in germany.
40 W * 24h ~ 1kWh
1kWh ~ 0.3€
0.3€/day * 364 days = 100€
half of the delta is more realistic for a FHD monitor, a 50W monitor is probably 4K so they're not really competing
I can see these used by companies that are forced to do so by some retarded EU regulation
