Nuclear wins at 75x

Solar PV with hydro energy storage loses at 2x, 4x without storage.

Per the author US needs 7x to be sustainable.

This is entirely suspect. Nuclear plants take about 10 years to build, and about 10 years to dismantle - and we have to store nuclear waste for millenniums - and they only produce power for about 50-60 years. Mining and refining nuclear fuel takes lots of energy. Shutting down nuclear plants every 18 months for several weeks for refueling, and major systems have to be repaired / maintained, requiring additional shutdowns.

The embedded energy of solar panels is covered in about 2 years, or less. They will last for 30-40 years.

Land based wind power is THE cheapest to build, now - and solar is the next cheapest.
