Michaux has been widely discredited. His 2021 report, for example, listed 65.4% of energy as wasted. That's probably true, most fossil fuel powered systems produce massive amounts of waste heat. But he still seems to think that we need to produce that much if we switch to electricity, which is obviously not the case.
Some of it is just misrepresentation. He uses Germany as an example, claiming they need 12 weeks of energy storage. The estimate he cites, which was already outlandish, actually says 24 days, and that's ridiculous. In the real world, there is no need for a whole country UPS because with enough renewables you only ever see hours of deficit, which can be covered with gas (only because it's cheaper to do that and offset it than to go 100% renewables/storage).
He also ignores all the HVDC lines that were being built at the time, and hasn't updated for all the once built since or announced since, so his estimate for the battery storage requirement is at least an order of magnitude off. He also bases his mineral estimates on old chemistry that was poor even when he wrote it, let alone today, and assumes it all has to be lithium ion battery storage.
He does the same thing with copper. Bases it off old technology, ignores aluminium as a conductor, ignores recycling, and vastly over-estimates the requirement.
The whole thing is full of obvious holes. Reality is that most countries can get to over 95% renewables + storage, and then some other sources for the remaining few percent which can have carbon capture and offsetting to reach net zero. The result is cheaper energy and a small chance we might not completely bugger up the planet.
