Understanding MW vs MWh: Power and Energy Explained

Here is the difference: megawatts (MW) measure real power and megavolt-amperes (MVA) measure apparent power. Real power is the power that gets converted into useful work: illumination, cooling, movement, etc. The relationship between MW and MVA is called power factor - a measure of how effectively power is being delivered.

Energy Storage | Applications | Capacitor Guide

Capacitors used for energy storage. Capacitors are devices which store electrical energy in the form of electrical charge accumulated on their plates. When a capacitor is connected to a power source, it accumulates energy which can be released when the capacitor is disconnected from the charging source, and in this respect they are similar to batteries.
