- uoaei 5y agoWatt-hours are energy. If cost of energy is decreasing and you get more lumens per watt with LEDs then the benefits stack, they do not cancel.
- zargon 5y agoIf energy price is going down, then even more watts are being bought (since spending is fixed).
- uoaei 5y agoNot all those watts are going into lighting. If spending is fixed on lighting but total expenditure is up that means energy is being bought for things other than lighting. Kirchoff's law applied to the grid in toto. Adds up considering the proliferation of computing devices, particularly cryptomining.
