If you have a 400 watt light it will cost you the same amount of electric each month no matter if it is 120 volt, 208,240 or 277 volt.
If you are wiring up a new building you can put more fixtures on smaller wire at higher voltages which will save you money on building costs. If the building is existing and already has both sources there really is not much difference.

REALLY???? It all relates to the process of VARS = Volts, Amps, and Reactance. That is what the electrical grid works with and the electrical generation companies use that to measure their work on the grid. If you are drawing a high resistance, then your meter is reading that and the house load moves to your home and not on the grid. As a nuclear worker, you just gave me a pay raise. Here in about 24 hours, the grid is going to see a lot of load increase in the residential areas, but the loss of all of the industrial loads will counteract that and the grid will stay stable.
The more you use, the more the watts are changed in the formula.
1 var = (1 Volt) x (1 Amp that is 90 degrees out of phase with the 1 Volt)
var = Volts x Amperes x sine theta where theta is the phase angle between load Voltage and load Amperes.
The magnitude of var (imaginary power) is the opposite side of the power triangle formed with the magnitude of Watts (real power) as the adjacent side and the magnitude of Volt Amps (apparent power) as the hypotenuse.
