Daily Total Generation by Generation Source (mWh)

Daily electricity generation mix by source shows how the U.S. grid is shifting in real time between natural gas, coal, nuclear, wind, solar, hydro, and batteries. Tracking these mix changes matters for reliability and resiliency because higher reliance on weather-driven renewables or aging thermal plants can raise outage risk during extreme heat, cold, or storms, helping consumers and journalists understand when grid stress and power interruptions are more likely and why plan choice on Gatby matters.
