Pathways to Achieve 100% Clean Power in the US by 2035

Wind and solar provide most (60%–80%) of the generation in the least-cost electricity mix in all the main scenarios. Nuclear capacity more than doubles in the Constrained scenario, reaching 27% of generation, while limited growth in the other three core scenarios results in a contribution of 9%–12%, largely from the existing fleet. The overall generation capacity grows to roughly three times the 2020 level by 2035, including a combined 2 TW of wind and solar.
