Fair point on the concentration. I concede. I will have to adjust the number, but I suspect it will still be in the 1e4+ range. In the meantime I'll pivot to the fact that seawater uranium extraction (while currently more expensive than mining) is renewable on a world-scale. It replenishes through rain runoff and plate tectonics faster than we could ever use it, even if triple the world's current consumption was provided by 100% nuclear.
Off-grid power is very small compared total energy used in the USA.
- Retric 10y agoIf you run the numbers there is a surprising amount of solar lighting for example in the US. Solar hot water heating and passive solar are also not counted in these numbers. The single largest energy use in the US is of course growing plants, but nobody thinks in terms of 'solar power'. While a reasonable argument that this should not be counted, bio fuels are used as an energy source. So sure, grid connected PV solar is a very useful comparison point, but the others are used to fulfill our energy demands.
