Great analysis. I would like to add a few more points.
Energy extraction from oil is typically a low efficiency cycle. ICEs are around 30% efficient. Gas Plants are around 40% efficient.
Energy from solar -> batteries -> application usually hovers around 70 - 80% efficiency.
Motors are around 98% efficient. That covers most of our requirements for manufacturing. Conversion of electricity to heat is almost 96-98% efficient.
- pfdietz 5y agoCombined cycle gas plants are about 60% efficient (on a LHV basis). Large marine diesel engines can have a thermal efficiency > 50%.
- folmar 5y ago> Energy from solar -> batteries -> application usually hovers around 70 - 80% efficiency. Nope, energy from solar is around 20%, batteries are at around 90% efficiency.
- creato 5y agoThe dollars per unit energy already includes this inefficiency of photons to electricity though. You are double counting it.
