Americans Are Rushing to Get Off the Grid

For years, Americans have been blanketing their homes with scads of solar panels. Now, they’re adding a growing number of batteries to store that electricity and protect against blackouts.

Battery storage in US homes surged by 64% in 2024 compared to the previous year, outpacing increases in commercial and utility installations, according to new data from Wood Mackenzie and the American Clean Power Association, a trade group. These storage units are now in about half a million homes and collectively hold 3,028 megawatt-hours of electricity.
