Water, power, and severe weather, could be a problem anywhere in the US.
Yes, bad weather comes and goes all the time. That's why in the US there are Eastern power grid and Western power grid to prepare for it, except Texas. When Texas desperately needed additional power to make up the shortage due to weather and failed power generation capabilities, they don't have any way to get help from other states.
It's because the Texas power infrastructure is isolated from the rest of USA. It's Texas's choice and weather didn't force them to make this unwise choice.
