Q:

Does removing an LED bulbs from fixture decrease energy usage?

Noob question alert. Electrics have always been my weakness. 
If you have a 6 bulb ceiling light, with 6 LED bulbs each with 5w, and you remove 3 of them, does this half the energy usage when the light is being used?
I guess this can also be re worded to ask whether, if you remove the LED bulb from a light fitting and it is switched on, does it use any electricty?
Thanks
Edit to add some background:
We are renovating our house and we have a room with 6 bulb ceiling light. It's far to bring for the replaced LED bulbs. We will replace the fixture in the future and my thoughts were, if removing bulbs still uses as much electricty, then I will change the fixture sooner. If it uses electricity relativing to only bulbs attached (ie no "Dripping electricty", good ref) then changing the fixture is not a priority. 

A:

Yes, that will cut energy use in half, though the type of bulb (LED, CFL, incandescent, one that's not invented yet) does not matter.
Of course, you also get half the light.
A bulb which is removed does not use any electricity whether or not the fixture is switched on (James Thurber's Grandmother notwithstanding, for the literarily inclined.)
