    I fail to see the problem. You cool your house down while the sun is up and even if it is still hot outside, then your house gets a bit warmer, so what? Still it is comfy inside and in the night you can open everything up to get some fresh wind in.

      This is what I do, but there are still problems. Some people are at work and don’t have programmable thermostats. If you have a poorly insulated house, even if you do pre-cool in the middle of the day, by the time late evening rolls around, it can be getting quite hot again. And during extreme heat waves, the overnight temperature can remain very high. Last night I went to open my windows around 10 PM but it was still hotter outside than in my house. And yesterday wasn’t even particularly hot where I live, the high was only in the low 90’s.

          Even in the desert it can be an issue. Phoenix had an overnight low of 97 this summer. Soon that may be commonplace.

          Part of the problem is poor planning by utilities but our systems are also being tested by weather that is truly unprecedented in human history. Our grid, and our strategies for keeping cool were developed in a different climate than the one we now inhabit.
