What are we wasting it on? Why will we suddenly stop wasting it when we switch to solar/wind?
I would think switching completely to solar/wind would massively increase the amount of wasted energy, because solar and wind energy production is quite variable, so to meet people's needs at low production times, we need to overprovision our production.
- ZeroGravitas 2y agoIt's wasted as heat when converting to electricity, or as heat when running an engine, or wasted in low temp heating when a heat pump could be 4x as efficient. Most predictions are that developed nations will double the amount of electricity they produce to electrify transport and heating but this will still reduce total energy due to the reduction in waste heat.
