Renewable generation output (wind and solar) plays a big role in determining electricity prices. When wind and solar production is abundant, wholesale prices typically fall because cheaper renewable energy displaces more expensive gas or coal generation. When renewable output is low, grids rely more on higher‑cost fuels, pushing rates higher.
Renewable Generation Output (Wind & Solar)
25% share
Direction: Up
Renewable generation (wind and solar) is expected to provide about 25% of U.S. electricity in 2026, up from around 24% in 2025 as more solar and wind capacity comes online.
Past Year Trend for Renewable Generation Output
Wind and solar generated a record 17% of U.S. electricity in 2024, up from around 15% in 2023 and about 12% in 2022. This rapid growth means renewable generation is expanding and surpassing coal, helping to moderate electricity prices.
