Is electricity wasted if a light switch is on but no bulb is in the socket?

I have several lights that used three bulbs. I want to change to CFLs to save both money and electricity. Will less electricity will be used if I use just one CFL bulb and leave the other two sockets without a bulb? Thanks.

No electricity will be used in the empty sockets, provided that they remain empty. However, the center conductor at the bottom of the socket continues to be live. This can present a shock or fire hazard if you have small inquisitive childrem that like to explore holes by sticking fingers or foreign objects into them.

No !!!
Dont worry, If there isnt a bulb in you will not waste electricity.
An empty socket does not leak electricity. so no energy is wasted. justr less light produced.
