The table linked lists the following lifecycle emissions (min/median/max) * Hydropower: 1.0/24/2200 * Concentrated solar: 8.8/27/63 * Rooftop Solar PV: 26/41

The table linked lists the following lifecycle emissions (min/median/max) * Hydropower: 1.0/24/2200 * Concentrated solar: 8.8/27/63 * Rooftop Solar PV: 26/41/60 * Utility Solar PV: 18/48/180 * Wind Onshore: 7.0/11/56 * Wind Offshore: 8.0/12/35 * Nuclear: 3.7/12/110 I've gotta say, Nuclear/Utility Solar/Hydro all have massive ranges in their lifecycle emissions. If you're basing "which tech has the lowest lifecycle emissions" from the median alone, you're not getting the full story. Rooftop solar is a lot more consistent than Nuclear, for example.
