HowisElectricalEnergyMeasured?Electricalpower is therateofenergy flow,and ismeasuredinWatts(W).Electricalenergyisequalto electrical power multiplied by the time it isused, and is usually measured in Kilowatt-hours(kWh).
A gigawatt hour (GWh) is equal to one billionwatt-hours or one million kilowatt-hours. NWTcommunities used about 370 GWh in 2014-15
