Yes, it does. The energy has to come from somewhere. It's a negligible drain, but it is a drain.

If I go and start my car, leave everything off, the engine will turn at 850 rpm, if I turn everything on, it will still turn 850 rpm.

The alternator is running either I'm using all my electronics or not, the overcharges just get grounded to the frame of the car. so no, it wouldn't.

Once again:
A) It does use gasoline.
B) It is an incredibly minuscule amount, and you'd never notice through normal observation.

Your link send me to a blank page.

As said, it doesn't. the charge of your alternator doesn't change either you are using your electronics or not. it will remain at a 12-14 volts charge rate. The sprung rate of your alternator DO require gasoline to create its charge yes, but it spin if you're using them or not. So the activation of your electronics do not change anything to the gas consumption.

F = ma + (P0 +Tw)/v + mg(mcosq + sinq) + (rAf + m/x0)v2/2

Every extra load increases the power consumption of the alternator to maintain it's 'nominal' level. It is an extremely small percentage, but it exists.

Does adding a grain of said to a beach increase the size of the beach? Yes, but only by an incredibly small fraction. Same thing here. You're never going to notice the difference, but the difference does exist.

That does make sense, but here what I did yesterday:


I went and filled my car to full, drove an hour with no electronic on, ended up costing me 9,56 $, than I went back to the same road, with all my electronic on, went back to fuel up, 9,56 $. This amount is so small that it didn't even show up on even a liter or a cent worth of gas. So I this point, I might as well keep on saying that it doesn't consume gas given that the alternator probably produce a greater charge than what would be required to run all my electronics.

If we're talking technically/scientifically, then it consumes gasoline.
If we're talking practically/realistically, then it doesn't*.

Never said you needed to have the engine running. Just like I don't need my laptop plugged into the wall to use it. That's how batteries work.

However:

Gasoline is required for a combustion engine to run.
The combustion engine powers the alternator.
The alternator charges the battery/powers electronics.
The battery powers the electronics when the alternator isn't active.

Unless you are charging your car battery using a separate method than the normal alternator, then the electricity created by the alternator or stored by the battery (other than it's initial charge at time of purchase), comes from the power of the combustion engine. Which is powered by gasoline.

Therefore, using the electronics of the car, powered by the battery/alternator, does cost gasoline.

But I did say that the engine consumption isn't affected by the alternator running, since the MPG is calculated with it bolted onto the engine.

So no having a certain electronic doesn't use more fuel than the engine require.

The original energy source is still the gasoline/combustion engine.
Is it a truly significant amount? No. But that's not the point of robuntu's post.

You still don't need to have the engine running to operate any of these thought.

Well, cars like that shouldn't even have backseats imo.
