... and the low end of the range is 72%, which leaves many more hours unaccounted for. Some amount of reliable, clean power is needed on top of the renewables.
- bryanlarsen 5y agoYes, the abstract sucks. Those are the numbers without batteries or over-building. To get to 99.99% you have to add all the mitigations: 3x overbuild, 3 hours of batteries and a continent wide grid.
