> Renewable energy sources have zero fuel costs.
That's not true. It costs fuel to mine the resourses needed, to build the equipments, to install them, to maintain them. The IPCC states that globally, nuclear power emits _less_ greenhouse gases than hydro and solar, and emits about the same as wind. [1]

- foxrob92 6y agoThe 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.
