Climate change is no longer a distant threat but a present reality, with a 78% rise in weather-related power outages in the U.S. over the past decade. Our high-resolution analysis of power outage data reveals that hurricanes, flooding, and heatwaves threaten over 60 million people along the U.S. Gulf and Eastern Coasts. During our long-term decarbonization pathway, integrating renewable energy like solar and wind into the grid has introduced new vulnerabilities. Hurricanes not only damage solar panels, their massive cloud structures can also reduce solar energy generation. Wind turbines are limited in their operational capacity during hurricanes. To better understand this risk, we downscaled global climate models and used physics-based climatology methods to project future heatwave and hurricane patterns along the U.S. Gulf and Eastern Coasts. Under moderate and high emission scenarios, projections until 2050 indicate higher frequencies of extreme events, particularly in high-latitude regions like New England. Our socioeconomic analyses predict at least an annual increase of 1.38 million affected electricity customers, with a $40.7 billion loss for a net-zero grid by 2050 in the moderate emission scenario (SSP2-4.5). Beyond these challenges, renewables are naturally distributed, which can also provide us opportunity to fight against climate extremes. By decentralizing our grid to multiple microgrids using rooftop solar and batteries, we are able to achieve energy autonomy in our communities.
