How much gas am I wasting by kegging a small batch in a 5 gal keg?

You drive a car without understanding all the fine details of combustion engine. You use computers and phones without even knowing how transistor works. Never mind a modern silicon based CPU.

What's the problem again?!

I drive the car, not take apart the engine, lube it, replace some parts and put it back together. But, point made. I'm sure I'll get on the keg wagon.
