Yep, this is the thing no one is talking about. Dallas has easily added 10k apartment units in the past 5 years. Almost all of them are all electric (no gas heating).

Considering it’s more energy efficient to cool with Air Conditioning on the hottest summer days than it is to heat with electricity in the winter, it’s no wonder the grid collapsed when the region was below freezing for several days and some generating capacity was lost.

Pretty sure you are off by a large factor. It looks like Dallas added almost 300k apartments in the last 5 years.

I think Texas as a whole has seen a huge growth in population in the last 10 years.

Resistive electricity will be close to 100% efficient, and heat pumps even higher depending on the outdoor temperature.

What kinda of air conditioners beat that for efficiency? I don't think we covered those in heat engines

[andbberger]

Air conditioners are heat pumps. Resistive heating is inefficient compared to burning something, and very inefficient compared to heat pumps

In addition to the other comments your missing the heat delta.

We commonly cool from 100 to 70F, or 30 degrees.

Yesterday we were warming from 0 to 65, or a 65 degrees delta.

All of them beat resistance electric.
