In February, a massive winter storm led to a power outage in Texas that left more than 4.3 million households, around one third of the state’s electricity customers, without power for several days amid freezing weather. Over 46 gigawatts of power capacity went offline under the extreme cold weather event, resulting in broad-based failure of the power grid. The energy outages also affected the state’s water services, either making tap water unsuitable for drinking or stopping the supply altogether.
