In Fiscal Year (FY) 2022, federal agencies used more than 5.8 million megawatt-hours (MWh) of renewable electric energy—11% of total FY 2022 federal electricity use. The Federal Energy Management Program (FEMP) helps agencies meet statutory renewable electricity requirements and accomplish their missions through investment in lasting and reliable energy-generation projects and purchases.

FY 2022 Renewable Electricity Procurement Methods

Federal agencies procured 5.8 million MWh of renewable electricity using the following methods.

Chart breaks down the methods used to procure renewable electricity.

Procurement MethodMWhPercentage of 5.8 million MWh
Renewable energy certificate (REC) purchases2,358,00440.2%
Direct bonus and REC replacement1,550,45026.5%
On-site renewable energy1,325,16822.6%
Off-site renewable energy626,66710.7%

Renewable energy certificate (REC) purchases: RECs represent the renewable attributes of generation produced from renewable energy projects and are sold separately from commodity electricity. Agencies can purchase RECs to help achieve their renewable energy goals.

Direct bonus and REC replacement: Renewable energy that is produced on federal or Indian land and for which the agency owns the renewable attributes, referred to as on-site renewable energy, allows the agency to claim a bonus toward their renewable energy goal. An agency can own the project and RECs directly, or, if the agency gives up ownership of the RECs to another party, it can purchase replacement RECs to reclaim the bonus.

On-site renewable energy: Produced from projects on federal or Indian land where the agency owns the renewable energy attributes.

Off-site renewable energy: Includes both the renewable attributes (RECs) and the source electricity for the renewable attributes.

On-Site Renewable Energy Progress

In FY 2022, federal agencies used 1.32 million MWh of renewable electricity from on-site renewable energy projects—1.5 times more than in FY 2015, and 5 times more than in FY 2010.

Chart shows the progress of on-site renewable energy.

FY 2022 On-Site Solar Energy Generation

In FY 2022, federal agencies generated 784,695 MWh of renewable electricity with on-site solar energy projects. The top five states for federal on-site solar energy generation were California (173,927 MWh), Hawaii (100,517 MWh), Georgia (65,995 MWh), Arizona (62,916 MWh), and Texas (50,250 MWh). Solar generation is grouped into ranges in the map below.

FY 2022 On-Site Wind Energy Generation

In FY 2022, federal agencies generated 81,572 MWh of renewable electricity with on-site wind energy projects. The top five states for federal on-site wind energy generation were Texas (61,984 MWh), Massachusetts (10,619 MWh), Utah (3,421 MWh), Wyoming (2,284 MWh), and California (1,417 MWh). Wind generation is grouped into ranges in the map below.

Federal Renewable Electricity Requirement

In accordance with Section 203 of the Energy Policy Act of 2005 (42 U.S.C. § 15852), each fiscal year the federal government must consume at least 7.5% of its total electricity from renewable sources—referred to as the renewable electricity requirement.

As defined in 42 U.S.C. § 15852(b), renewable electricity is electric energy generated from solar, wind, biomass, landfill gas, ocean (including tidal, wave, current, and thermal), geothermal, municipal solid waste, or new hydroelectric generation capacity achieved from increased efficiency or additions of new capacity at an existing hydroelectric project. Nonelectric or thermal renewable energy, including geothermal heat pumps, does not count toward the renewable electricity requirement, but will be tracked as an indicator for an agency’s OMB Scorecard.

For most recent requirements, see Federal Renewable Energy Use Requirement: 42 U.S.C. § 15852(a) as amended by EPAct § 203 and the Energy Act of 2020 §§ 3002(o), 3006(b)(2) of December 27,2020, 134 Stat. 2497, 2512).
