The energy E in watt-hours (Wh) is equal to 1000 times the power P in kilowatts (kW) times the time period t in hours (h):
E(Wh) = 1000 * P(kW) * t(h)
Watt-hours = 1000 * Kilowatts * Hours
Wh = 1000 * kW * h
Find the energy consumption in watt-hours when the power consumption is 5 kilowatts for a time duration of 3 hours.
E = 1000 * 5kW * 3h = 15000 Wh
