What are the causes and consequences of the increasing power grid failures across the United States?

Power grid failures in the U.S. have dramatically increased, with annual blackouts doubling from 2015 to 2020. Major incidents like Hurricane Ida's impact on Louisiana and the Texas winter storm demonstrate how aging infrastructure struggles against extreme weather events, which are becoming more frequent due to climate change. The consequences extend far beyond mere inconvenience. Power outages disrupt critical infrastructure including sewage treatment plants and water purification systems, creating cascading public health risks. Most seriously, outages threaten lives of people dependent on medical equipment like ventilators and powered wheelchairs, making reliable electricity a matter of life and death. The situation represents a critical infrastructure crisis that demands immediate attention and significant investment in grid modernization to protect communities from increasingly severe weather patterns.
