Power in WATTS is Voltage times Amperes.
If you simply plug in, and do not turn on any loads, you
are using 115 Volts times 0 Amperes = 0 Watts
If you add load, say 10 Amperes, you are drawing
115 Volts times 10 Amperes = 1150 Watts = 1.15 Kilowatts
This holds for a 30 Amperes rated circuit, but not for other
types of circuits.
