Golf facilities require a large area and consume energy to operate. As such, golf facilities have the potential to influence ecosystems and contribute to national and regional energy demands. The objective of this study was to document the land-use and energy practices of US golf facilities in 2021 and to determine if changes have occurred since 2005. A survey was distributed via e-mail to 13,938 US golf facilities, with 1861 responding. From 2005 to 2021, the projected acres of maintained turfgrass declined by 14.2, whereas the median maintained turfgrass acreage declined by 3.0 indicating the decline in projected acres was likely a result of facility closures. In 2021, water features, turfgrass, and natural areas accounted for 92 of the total projected facility acres. More golf facilities used cleaner energy sources, such as natural gas and solar-electric, and fewer golf facilities used gasoline and diesel in 2021 than in 2005. The percentage of golf facilities at which behavioral changes were implemented to decrease energy use declined but design changes increased from 2005 to 2021. Golf facilities became more land and energy efficient from 2005 to 2021 by reducing the acreage of maintained turfgrass and increasing the use of clean energy sources, but room for improvement still exists in human behaviors that affect energy use.
