My parents live in Dallas and rarely use the heating because of cost; instead they wear scarves and mittens inside. They are running it now, because it is the coldest they've ever seen. When your alternative is to freeze to death, you pay. Finding fault with people because of that is insensitive and lacking in empathy. They know the cost, they also know what the temperature outside is.

Resilience is an important principle in engineering, we know that from software, but it is even more important in infrastructure. People rely on this for staying alive. It is important to have a diverse set of electrical generators. Atomic energy and coal are very resilient. As someone else pointed out, a lot of green infrastructure is prone to failure in extreme events. The wind turbines froze. When the sun isn't shining the solar doesn't work, and it is coldest at night. It is great to have green infrastructure _with_ other types. This stuff is way to important to play politics with.
