...”swamp coolers” (Yes, they still work in normally dry West Texas)

In mid-summer in the Upper Midwest, the humidity can be 100% even if it’s not raining.
83 indoors happens to be my personal threshold for a/c. That’s upstairs, which is a converted attic with windows on all 4 walls. The computers and printers are up here. High humidity is horrible for both.
Once it’s at 74 and the humidity under control, I turn it to *efficiency*. We haven’t needed a/c at night for years. We stopped using the window unit in the bedroom maybe 5 years ago. We used the portable a few times 2-3 years ago (can’t recall exactly). It has stayed under 70 at night in the hottest part of the year and a ceiling fan and box fan, together, suffice. At the worst, those temps last maybe a week.
Recently, some millennials were up in arms because their college dorms weren’t air conditioned. They complained and were told to use fans. They did not accept the response gracefully, if at all.
As for the light bulbs, we changed out everything to LEDs and never saw the promised savings.

I recently bought some high-dollar LED bulbs. Supposed to last 13 years. 10 months is more like it.
The LED bulbs were another scam. They don’t last nearly as long as they said, power supplies run hot and failed early.
And I have difficulty reading in the light of LED lighting.
LED lamps work a lot better on DC than AC. Low voltage DC power for LED lights is an efficient method. But poor quality lighting.
