Louisiana is the #2 state with the most power outages in the last year

An aging power infrastructure and a growing climate crisis have left U.S. residents increasingly in the dark. Traditionally, power outages are caused by singular disruptions—a car rams into a pole, equipment fails, or a tree falls onto a power line. These incidents usually affect small areas for short periods. However, as the changing climate spurs more natural disasters, power outages also become more frequent and severe.

Stacker analyzed data from the Department of Energy to identify the states that have experienced the most power outages since the start of 2021. Data was available through June 2021, so it does not include more recent natural disasters like Hurricane Ida. These states do share one severe weather incident: the arctic blast that caused record low temperatures across 48 states in February 2021.

- Total electric disturbance events (2020): 18
--- Most common cause: severe weather

Hurricanes in Louisiana have contributed to power outages vast in both quantity and scope. Hurricanes Laura and Delta touched down just six weeks apart in 2020. One utility company, Entergy Louisiana, had nearly finished restoring power to those affected by Hurricane Laura when Hurricane Delta led to outages for over 300,000 of its customers. Overall, more than 600,000 Louisiana residents lost power as a result of Hurricane Delta. In May 2021, flash flooding in Louisiana led to four deaths, including an oxygen-dependent older man who died from oxygen failure during a power outage.

These outages are life-threatening in more ways than one. Power outages leave residents without air conditioning or heating, making them susceptible to heatstroke or hypothermia. Furthermore, improper use of alternative energy sources like grills or gas-powered generators can lead to carbon monoxide poisoning.

During an outage, hospitals resort to contingency plans to power only the most vital equipment. Accessibility is hindered as motorized stair lifts and elevators stop functioning. Prolonged power outages also disrupt the food supply chain. Factories pause or halt production, warehouses stop loading trucks, and stores lose perishable food.
