Personal Energy Calculator Developed by Dr. Walter Ernst in 2002 for the Youth Encounter on Sustainability (YES), Edited by Dr. Jeffrey Steinfeld and Beth Conlin. Please enter consumption estimates for the following tasks. Use the provided conversion units to convert to kWh. Task Conversion Factor Household: Direct energy: residence - area heated m 2 x 25-170 kWh/m 2 y = kWh/y residence - area air conditioned m 2 x 5-15 kWh/m 2 y = residence - electricity m 2 x 18-28 kWh/m2y = Indirect energy: residence - total used area m 2 x 55-67 kWh/m 2 y = Total Household kWh/y Mobility Car Direct energy: fuel [Liter gasoline per year] L/y x 12 kWh/L = Indirect energy: km driven per year km/y x 1.2-1.4 kWh/km = car weight kg x 5.3 kWh/kgy = Public Transport Train km/y x .5-.9 kWh/km = Bus/Boat km/y x .15-.8 kWh/km = Aircraft [hours per year]
