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.

State Energy Data System (SEDS): 2021 (updates by energy source)

New releases of energy consumption, price, and expenditure estimates by energy source. See Additional information.

A set of updated data files is presented under Data files. The "2021P" in the data_status field indicates that these are "in progress" estimates generated from the 2021 data cycle. These files incorporate the latest estimates and revisions that have been processed in SEDS. They are updated every time a new set of SEDS estimates is released.

The full set of estimates for the 2021 data cycle was released on June 23, 2023 with a data_status indicator of "2021F." See SEDS Complete for more information.
