It'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.

It'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.
