I'm using table 1.
PV panels alone produce 43g/kWh, batteries 33.
Nuclear (light-water or pressurized) are at 12.
We're talking complete life cycle analyses.
To tack onto that: https://ourworldindata.org/land-use-per-energy-source
When you account for land use in the entire life cycle from mining resources to disposal at end of life cycle, nuclear uses a quarter of the land of rooftop cadmium panels and a tenth of silicon panels.
Offshore wind is the only thing that gets close and even that has ecological and commercial concerns.
If you're pro-stable and sustainable ecological systems, nuclear based power grid is a no brainer.
