They're like that in this apartment we're renting and I keep seeing them elsewhere. I don't get it.

No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

Having grown up with it I missed those tbh. Makes saving power easier lol
Does it? Can't you just turn off the device instead?
yes.
Im from the states and live in Ireland. Here, people unplug lamps when they leave for the weekend. Dozens of times, I've had to plug lamps back in when coming into the office over a weekend or things like Christmas break.
I've also had to explain to at least 5-6 people that something that does not draw power by being plugged in, such as a toaster, electric kettle or light fixture (unlike a computerized device that has a stand-by mode) is not "wasting power" unless you unplug it or turn the outlet switch off.
I had a person at a party tell me their father was an electrician and taught her to turn the switches that lead to anything such as lamps OFF when they're not being used because it costs electricity to "keep the wire charged". True story.
Mainly they exist because there weren't central fuse boxes for a while due to wartime copper shortages.
Lol what a donkey. For anyone that's unaware, your meter spins when current is flowing, when a device is actively using power. If there's no current flowing, the meter isn't spinning. Just because a wire has potential doesn't mean it's actively drawing current, it only means it's ready to do something, and any device that has the main feeder going through a physical switch (ie no standby like a computer or tv) has zero current path when the switch is open/off. Even devices in standby are drawing such a negligible amount of power that it doesn't matter.
My mom used to unplug everything all the time, and it took years to convince her that's not how that works. She only finally got it when I became an electrician.
You can test this theory yourself if you have a multimeter. Select ohms/continuity, and put the leads across the two prongs. If there is a resistance value present, it will draw current. If it says OL or 0 ohms, that means open line and it won't draw anything.
the only thing that would make a shred of sense would be reactive power from plugged but unused transformers and the like, and for this reason you should disconnect these when not in use. but the only loads of this type that matter are welders and such
Someone elsewhere in the thread pointed out that the Wikipedia page for BS 1363 says they’re optional and weren’t added to the standard until 1967.
huh! shit. thanks
A lot of devices can be turned off, but they still use power. So you can waste electricity even though the devices are "off".
Things like normal table lamps aren't the problem, it is stuff like TVs, computers, stereos, etc.
