how many kWh does one person use per day
That is like 12.5 gigawatts per million people or 12.5 kW per person. To be sure, that must be a cost of $0.63 an hour or about $15 a day just for energy. Lots of people must be using a lot less than that $15 a day.o find out how much energy you use directly in appliances, it's probably easiest just to watch what you do each day and write it down. Add up your energy usage for your house on your electricity meter for a month (usually in kWh) and divide it by the number of days in the month and the number of people in the house.
