How are energy and power "loose terms"? Energy might be difficult to fully explain rigorously, but it's one of the fundamental elements of our universe. And power is just energy over time

Well, you yourself just provided the example, since your definition of energy and power are the inverse of the definitions used in the video.

It’s the fact that people use them differently or interchangeably that makes them “loose” IMHO.

He’s making a point about instantaneous versus overall energy use, which it sounds like you already understand. “Power” and “energy” are kind of loose terms IMO, which could confuse that conversation a bit.

But for anyone still scratching their head:

The typical energy consumer need only consider watts (w, kw) when accounting for circuit capacity. For example, if your hair dryer pulls 1600 watts, don’t use it on a 1500 watt outlet, or you will likely trip the circuit breaker.

Otherwise “watt-hours” (wh, kwh) is likely the metric you’re looking for when considering energy use. This is a certain amount of power drawn over a period of time, where 1 watt over 1000 hours and 1000 watts over 1 hour are both equal to 1 kilowatt-hour (kwh), which is the standard unit you likely see in your electric bill.

It’s why low but constant power draw can significantly impact energy use. For example, a typical laptop pulls fewer than 100 watts, lower than many appliances in your house, but if it draws that much power all the time, it might significantly impact your electric bill. Conversely, an electric kettle / coffee maker might pull as much as 1300 watts while in use, more than most appliances in your house, yet it probably represents a minuscule portion of your electric bill, since it only runs long enough to boil a small amount of water with each use.

Edit: include tea drinkers, add more concrete examples

The moment you subscribe, you might as well forget Apple exists.

Slight disagree on this point. Having subscriptions tracked in one place and easily cancelled with a single tap does offer simplicity and some peace of mind. Unfortunately companies sometimes do unexpected things with subscriptions.

For example, say you turn off auto-renew during a promotional period. Often companies will take you through a please-don’t-cancel workflow where you have to find the hidden confirmation button. Worse IMO is when they end the promotional period immediately if you don’t keep auto-renew enabled. Protection from stuff like that must have some value.

Yeah, it’s the nature of dog whistles but 88 is the only one I remember. Even so I’d probably assume birth year and think nothing of it, but I understand the concern.

Just like mom used to make.

The point isn’t really to inconvenience him though. It’s to cede no ground without documented abuse of power.

And then what happened?
That must be really hard for you.
Wow. You don’t deserve that.
How do you feel about it now?
Ugh. That sounds awful.
You’re handling this better than I would.
How do you even respond to that?
Tell me about it.
What can I do to help?
You’ve got this, but I’m here.

Edit: I wrote the above to illustrate how many options there are in the parlance of active listening. The formula is simple: imagine how they feel and join their side or, if you can’t yet imagine, ask questions until you can. That’s it.
