Probably they’d keep making money through ads, but less so since they couldn’t rely on their in-house ad monopoly, and may have to give a cut to a third party ad platform.

Yes and no.

Better store than loose energy.

But the choice isn’t between heat storage+conversion and no storage. It’s between differents type of storage (heat, chemical, gravity, electrolysis, freewheel), with multiple technology and chemistry to choose from for each type.

Since there’s many options to choose from, it make sense to compare overall efficiency and cost.

That’s a good article with lots of context on the issue.

However one thing is missing: round trip efficiency figures. The whole process of turning electricity into heat, then back into electricity, is probably low efficiency.

There is discussion of directly using stored heat for industrial processes or heating. That’s probably a better use of energy since it avoid some conversation losses.

A motion sensor in the hallway to turn on the light is handy. It can be found in most hardware store. No need for Internet nor Amazon account nor smartphone. Your grandma, grandpa, toddler, local burgler, anyone can turn on the light.

Science communication could use a few puns.
