I need to compare the energy consumption of an industrial machine before and after improving. Shall I compare the apparent power or the active power? I know usually factories use compensated capacitors (or other similar components) to compensate the reactive power, so if I use the apparent power, it's not the real power consumed.

Why reactive power is needed in a power system? How is it being absorbed or delivered by alternators? For reactive power control we are changing excitation but reactive power absorbing or delivering related to stator. How these two are interlinked? i want a detailed explanation with necessary expressions and figures?
