In February, Texas faced the startling reality of a changing climate with single-digit temperatures that led to widespread power outages, flooded homes and lives lost. But why was Texas hit with one of the worst blackouts in our country’s history? And why was its energy grid unprepared to handle it? This week, senior energy analyst Julie McNamara of the Union of Concerned Scientists helps us answer these questions, and Lori Landry, a longtime friend of Sec.
