Fortunately, the same American energy source that kept millions cool during the recent heat wave is already preparing to keep them warm this winter. Natural gas. It was natural gas leading electricity generation during peak hours in the Midwest, Mid-Atlantic, New York, and New England. At the height of the storm, natural gas, coal and nuclear combined to provide roughly 80% of America's electricity. U.S. natural gas production is expected to reach a record 111.25 billion cubic feet per day in 2026, up from 107.65 billion cubic feet per day last year.
