For well over 30 years I lived in a very hot area (summer would have days over 100 F - that's over 37 C). I remember when we had over 70 days in a row that way. The temperature overnight may drop by 20, if we were lucky.

Now I'm on the Gulf coast, but further south. It's not as hot (still hot, just not as hot), but very humid, so it may as well be that hot.

We live inside air conditioned homes, but that can become expensive, so we try to keep the use of the oven down, too. However, using an Instant Pot, Slow Cooker, or even a Rice Cooker can help. The Instant Pot, especially, will cut down since it is a much shorter cooking time.

Another thing we do is to cook outside on a barbeque grill. Not just the meat, but the veggies, too.

Anything to keep the temperature down to use less electricity on the air conditioning.

Funny thing, though, this year we have had cooler temperatures than normal.
