- Facebook monthly electricity bill = 1 Million USD  , and adds new servers every few days because users appetites for adding photos keeps growing.
 
- Youtube monthly bandwidth consumption= 25PetaBytes ( 1000 Terabytes )
 
I don't have the excat amounts but the above is a harsh reality of operating such services. Though their financial standings show as mighty, I wonder how long can they sustain just running just on large adverts?
