Equation for energy consumed
WebFind the daily energy consumption using the following formula: (Wattage × Hours Used Per Day) ÷ 1000 = Daily Kilowatt-hour (kWh) consumption Find the annual energy consumption using the following formula: Daily kWh consumption × number of days used per year = annual energy consumption WebOne kilowatt-hour is defined as the energy consumed by power consumption of 1kW during 1 hour: 1 kWh = 1kW ⋅ 1h One kilowatt-hour is equal to 3.6⋅10 6 joules: 1 kWh = 3.6⋅10 6 J The energy E in kilowatt-hour (kWh) is equal to the power P in kilowatts (kW), times the time t in hours (h). E(kWh) = P(kW) ⋅ t(h) Kilowatt-hour example
