60 watts to illuminate just one room used to be the norm. Now it sounds insane. Maybe losing the perfect color rendering index was a worthwhile tradeoff after all.

    It’s honestly amazing that we got quite some low-energy gear nowadays.

    I hope more hardware will get properly power-optimized. There’s no good reason your desktop should suck 600w out of the mains when -20% performance can convert to like -80-90% power draw, like it is in the laptops.

    My own setup uses less than half of that at peak (when my server is running at 100%, which is very rare).

    Then again that’s because my server is an N100 Mini-PC that doubles as a TV Media Player and which I chose explicitly for the low TDP of the CPU (just 6W).

    It’s actually pretty insane how mainstream PC tech for quite a while just kept going up in power consumption (hence people needing 500W+ power sources) until at some point there was a period when CPU and GPU makers actually made some effort towards better power efficiency, though that period is over and we’re back to graphics cards using so much power you need multiple standard molex power connectors to feed them.

    Multiple 60w bulbs!

    Chandeliers with 10 40w bulbs. Recessed lights - 4, 6, or 8 75w bulbs. It’s crazy!

    500w or 1000w street lights too. That’s one reason we can absolutely have street level charging, if the owner of the lights plays along.

      Street lights use sodium-vapor fluorescence rather than incandescence, which was actually more efficient than LEDs until a few years ago (and I believe that low-pressure sodium-vapor still is and only high-pressure sodium-vapor has been surpassed by LED tech).

      So there isn’t all that much power freed in replacing existing street lights lamps with LED.

      However that tech doesn’t really work well for lower power application such as home use, hence why people used to have 60W incandescent lamps at home or their fluorescent lamp equivalent (which is around 20W) that were replaced by first 10W LEDs and now even lower as LED light bulb tech has improved.

      Some places only permit electric utilities to sell electricity based on kwh usage, so it’s tough unless the electric company also owns the street lights. Otherwise you pay an hourly “parking” rate, not one based on electric consumption

    Sitting in my tiny Chicagoland apartment with my AC blown out, I could reach my arm out in the kitchen and feel the temperature from my single 60W bulb in the corner.

    A year or so ago I touched a 60W incandescent and about peeled skin. Forgot how much heat comes from a glowing filament!

    Anyone still call your power bill the “light bill”? :)

      I recently saw in a series or movie (I think it was Spider Noir) someone grab a naked lightbulb to stop it from swinging without any reaction whatsoever. I was screaming at the TV

    Y’all got some efficient machines. Meanwhile my server closet is sucking over 400W when taxed. It is 1 unraid server, 1 home assistant server, 1 Unifi dream machine, 2 switches (1POE).

    I guess it is not that bad overall. But how the fuck did we have houses using a bunch of 100W bulbs years ago but now we use less but pay way more.

    I’m often flabbergasted at tech YouTubers who complain about the high energy cost of their 20 watt or 14 watt home server.

    I’m like, you understand that we used to burn 2.4 kilowatts a day to light a single room, right?

      We also used to build houses to ‘breathe’, specifically encouraging air flow through the walls, etc. to carry away the water leaking in through all the unsealed holes, and allowing any efforts in heating and cooling to go out that same way. In the days of yore, the gas lines that fed English streetlamps with coal gas were allowed to just flow, even when not lit. It’s a wild thought to wonder how much longer the end of fossil fuels could have been put off if efficiency had been a priority from the start.

        If efficiency is key, burning things is out of question decades earlier.

        Because burning is never really efficient

      This is actually not entirely true if you have a heat pump.

      Heat pumps can be more efficient than electric / resistive heating since they just move latent heat around rather than having to create it from electricity. The heat itself is still not being wasted, but using an electric heater to heat a space will use more power than using a heat pump.

      Same. I’ve got my server racks in my den on my first-floor, and the heat fairly reliably and evenly rises to warm my second and third floors to comfortable levels.

    Mine is like 18 W idle, just the server. I did setup auto taking down some unused containers though
