Daily Renewables Share of Total Generation (mWh)
Renewables share of total U.S. generation tracks how much of today's electricity comes from wind, solar, hydro, geothermal, and storage-paired renewables. A rising renewables share often lowers marginal costs and is a useful signal for consumers comparing fixed-rate vs variable plans.
Key Insights
The share of U.S. electricity generated from renewables fluctuates daily, reflecting weather conditions and grid demand. Renewables regularly account for a meaningful portion of total generation, but variability underscores the importance of complementary dispatchable resources. Higher renewables share often coincides with lower marginal generation costs.
