{{p2|(example)|Suppose an [[electric car]] charger operates at 4800 watts, but the car is only charging for 2 hours per day on average. So the wattage ''averaged over time'' is 400 watts. Also note: If a family of 2 people owns 1 of these cars, then that's 200 ''watts per capita''.}} | {{p2|(example)|Suppose an [[electric car]] charger operates at 4800 watts, but the car is only charging for 2 hours per day on average.
