Morphology
MWh = megawatt-hour (transparent) = M + W + h
The abbreviation directly represents the unit 'megawatt-hour', so learners who know that unit can derive the meaning.
Etymology
MWh comes from three parts: mega, watt, and hour, where mega means 'million', watt is the common unit for electric power, and hour means 'time'. So an MWh is the energy equal to one million watt-hours, which is why we use it to talk about how much electricity a power plant makes or a city uses.
