Necessity is the mother of invention? I believe this current cold-snap is a record for Texas in the multiple day "hard freeze" department. They simply have never had this kind of event and therefore were not prepared for it. They'll learn from it and move forward with more robust infrastructure. You can bet more people will be winterizing their pools! But I also see them re-designing their windmills to handle the cold and taking other power infrastructure steps to avoid outages. It is different in the North where Windmills are largely "feel good" projects that provide nothing substantial to the power grid and could stop producing without anyone even noticing. In TX Wind power is 24% of their power. They cannot afford to lose 1/2 of that generation.
