This morning, as the jet stream brought frigid air south to the central United States, Texas residents found themselves facing rolling blackouts as statewide grid struggled to meet demand amidst a large shortfall in generating capacity. As the day wore on, many saw these blackouts extend for ever longer periods of the day, and grid authorities are expecting problems to extend into at least Tuesday.
