Yep, virtual lights work the same as real lights
If theyβre not looked at, they donβt consume as much electricity. So thereβs that difference.
If you have your back to them, they don't emit light either!
Edit: Well, reflections, for you with the FANCY GPUs...

And by convention, all vehicles in video games are electric.
Which is really unexpected if you're looking at an oil lamp.
Change electricity to energy and weβre good again
More interestingly, lamps in video games use the same amount of real electricity if they are on or off.
Not necessarily, on OLED displays (which are definitely a thing for desktop computers and TVs) a light that's turned off is using less power because the pixels the lamp is displayed on (and the ones around it too) are dimmer.

that consumes electricity. ever think about the poor gpu? about how your words hurt its feelings?
jokes aside the power to process a few hundred vertices every frame is insignificant
And traditional LCDs with a backlight use more power for darkness. The LCD is transparent by default and turns opaque/black when a voltage is applied.
Actually, the pixels go completely black and do not consume any electricity at all in that state.
You might be thinking of early OLEDs, which had to stay on at all times to prevent blur/smearing. But panel manufacturers solved that problem a few years ago. Don't remember exactly when the change happened, but I remember first seeing true black OLEDs sometime around 2017/2018.
When a lamp turns off it doesn't become a black hole. Previous commenter was correct, though I appreciate your info about OLED

Highly depends on the rendering engine and if youβre looking at it, as it could unrender if you look away, meaning less energy used.
Did you know that if we took all the rhinos left on the planet, put them in a rocket ship and launched it towards the sun, the would travel 91.511 million mi, and die along the way?
Akshually we currently have no rocket with enough power to launch that much mass towards the Sun. People always assume because the Sun has a lot of gravity, stuff moves toward it automatically. But when launching from Earth that's not the case. Earth is in orbit around the Sun, in order to get to the Sun you need to lose all that energy. Since rhino's are heavy af you'd need a mighty rocket indeed.
We could with some effort maybe launch one small rhino, say 600-700kg towards the Sun. And it requires some fancy ass orbital mechanics. So it would travel way more than 91.511 million miles before ending up in the Sun. This rhino would probably not survive the launch, which is just as well given its destination and travel time.

While getting a rocket or probe to hit the sun smack in the middle sounds hard to do, you can get obliterated by it with much less delta-v.
You need to get to the Earth's escape velocity and just cleverly align the angle of escape so that you get an eccentric enough heliocentric orbit that you'd end up some 6 million kms close to the sun. Anything closer than that is literally overkill.

So an oil lamp in a video game is actually an electric lamp?
Shades in video games use even more electricity
Not on OLED screens + prebaked lightning
Even if the lamps are off.
If you're using an older LCD screen, turning off the lamp uses more electricity than leaving it on
If the game is demanding enough they also consume the same amount of electricity, maybe even more.
But what about candles?
We should demand that they are oil lamps from now on to save the planet
Just make the player stumble in pitch black darkness through the entire game, duh.
Lamps in video games aren't real. It's the video game that's using the electricity.
Video games aren't real. It's the computer components that use electricity
computer components aren't real. It's all just tiny gremlins doing maths really fast and turning pixels on and off
Tiny gremlins aren't real. It's all just a dream. Wake up you have to make me breakfast. I would like pancakes please.

That's like saying "lamps don't create light, it's the flame/filament in the lamp that creates the light"
The lamp is rendered by small electric lights, be it LEDs or LCD. CRTs are in a bit of an grey area. But you can absolutely use a monitor as a light source by itself .
