calculating costs wants me to input my kilowatt charges so after looking
at my latest electric bill i have 3 different charges...power supply
energy 457 kwh @0.06726, distribution 457 kwh @0.04195 and energy
optimization 457 kwh @0.01081. i am not sure which of these numbers to
input into my kill a watt meter...any suggestions?

Add them together. As a check, add them, multiply by your usage, add the
billing fee or basic charge (if any), and compare to the bottom line.
