America's changing power grid faces a powerful El Niño

A powerful El Niño is expected to cause significant changes in electricity supply and demand across the U.S. this winter, challenging the nation's power grid. This event is particularly noteworthy because the grid now relies heavily on renewable energy sources like solar, wind, and battery storage, which were less prominent during the last major El Niño. The current El Niño could reveal whether these changes have made the grid more resilient or exposed it to new vulnerabilities. As weather patterns shift, the implications for energy management and infrastructure resilience become increasingly critical.
