State Profile and Energy Estimates

Changes to the State Energy Data System (SEDS) Notice: In October 2023, we updated the way we calculate primary energy consumption of electricity generation from noncombustible renewable energy sources (solar, wind, hydroelectric, and geothermal). Visit our Changes to 1960—2022 conversion factor for renewable energy page to learn more.

Notes & Sources

-- = No data reported.
*  = Value is less than half of the smallest unit of measure (e.g., for values with no decimals, the smallest unit is 1 then values less than 0.5 are shown as *.)
NA = Not available.
NM = Not meaningful due to large relative standard error or excessive percentage change.
W = Withheld to avoid disclosure of individual company data.
Note: Small differences between source data and values displayed here may be due to independent rounding.
Note: Components of "Utility-scale net electricity generation (share of total)" may not add to 100% because "Total utility-scale net electricity generation" includes net generation from petroleum coke, pumped storage hydroelectric, other gases, and other energy sources, which are not shown separately.
Note: Territory data may be estimates based on EIA's Short-Term Energy Outlook.
