Power factor.
VA only equals watts in a purely resistive circuit (PF=1). In an AC circuit if the current sine wave leads the voltage sine wave (capacitive load), or the current sine wave follows the voltage sine wave (inductive load) the apparent power (VA) is higher than the actual power (W). PF=W/VA

I'm gonna need to do some googlage to understand this, but thanks for the explanation!
