What it’s like

The place. Energy is a small village in Williamson County, in southern Illinois, with a population that stays small even by the standards of villages. Most homes are lived in by their owners, and typical home values are modest. Winters are cold, with some snow, and summers turn hot, with plenty of rain and melted snow across the year.

Work. Residents work mostly in schools, hospitals and social care, followed by shops, manufacturing, and banks, insurance and property. Across Williamson County, the largest workplaces include Aisin MFG. Illinois, which makes sunroofs and automotive parts, the Veterans Health Administration, and Herrin Hospital. Unemployment in the county is lower than a year ago, and the county has added jobs. Commutes are fairly short, and few people work from home.

Things to do. Crab Orchard Lake, a reservoir, and Crab Orchard National Wildlife Refuge, a protected area, are both a short drive away. The Little Muddy River is also close by. For a longer outing, Giant City State Park and the Shawnee National Forest are a longer drive away.

FEMA’s National Risk Index (December 2025) rates the risk each natural hazard poses to the people, buildings and farms in Energy’s census tracts, against the rest of the country; all of them together, relatively high. It is meant for planning, not a substitute for a local risk assessment or a flood map: FEMA’s index.

From the U.S. Census Bureau’s 2020 census and its American Community Survey (2020–2024 five-year estimates), and the Bureau of Labor Statistics. A survey, so each figure has a margin of error, and figures it is not sure of are left out. More on Williamson County and the Carbondale-Marion, IL metro.
