Thanks for sharing, Jerry.

Interesting is this section:

“The U.S. Department of Energy commissioned a study in 2019 which predicted that the higher energy efficiency of LEDs would mean that the amount of power used for lights at night would go down, with the amount of light emitted staying roughly the same.”

But what happens is that the Jevons Paradox is at work i.e. when a resource is used more efficiently (meaning less of it is needed per unit of output), the lower cost or greater convenience can make people use more of that resource overall, not less …
