My boyfriend tells me that a vehicle will use more gas while idling than while actually moving. Is this true? And if so, how? He also says that a computer uses more electricity when you boot it up than when its just on. If you know this one too, let me know.

I think that Lance, Louie and James are all correct. I would suggest that you find a vehicle with a tachometer - they are not uncommon. This gauge tells how fast the engine is running in revolutions per minute (rpm). More rpms equal higher fuel use. With the engine idling, what is the reading on the tach? It is probably something like 850rpm. This number would be somewhat higher if you are cold starting. Now drive the car around the block - conservatively. What was the highest reading? Maybe about 2,000rpm? Could be a lot more, or a little less. Do you think the engine was using more gas at 850rpm or at 2,000rpm?
I would guess that a pc on power up would be doing more work than at steady-state "on" largely due to the drives running. After some small amount of time, power use falls to its normal level. Since the powering up stage is short and the "just on" stage is probably much,much longer, I would say that any small difference in power consumption is lost in the usual variations of ordinary use.

He just means that when you are idling you are using fuel and not going anywhere. you are technically getting zero miles per gallon when you are sitting there idling. The car doesn't use much gas when you idle, but it's still burning some.

Could be. When a car is cold, and idling is does use more gas because the engine is not up to proper operating temperature.

No your car does not use more gas at Idle, it uses more when you step on the pedal requiring more fuel to be injected into the cylinders to obtain the speed you desire, and the faster you drive the more you burn.

I know about the computer. its true it takes more energy to turn it on and off then to just keep it running. It takes more energy to do so because when you first power it up it needs to start the entire motherboard an all programs to get this pc running. Once running it takes little energy to just keep it sitting there. Also many pcs now go into a save mode which conserves energy if runing without usage for a while.
