Extreme Weather’s Growing Threat to Power Grids: Millions at Risk

As the climate warms, extreme weather events are becoming more common, placing immense strain on power grids across the United States. The consequences are dire: widespread power outages, health risks for vulnerable residents, and a looming threat to critical infrastructure. Scientists warn of an increase in the frequency of extreme weather, including storms, wildfires, and heatwaves, leading to more frequent and severe power disruptions. While most outages are localized, the Texas freeze of 2021 highlighted the catastrophic potential of system-wide failures. The lack of power during extreme heat or cold can pose significant health risks, particularly for those with underlying medical conditions. Experts emphasize the need for investments in grid resilience and adaptation measures, including maintaining aging infrastructure, burying power lines in vulnerable areas, and promoting energy efficiency.
