That is like 12.5 gigawatts per million people or 12.5 kW per person.
PS, kW per month is meaningless. Perhaps you mean kW-hour per month. If you take the 800 watts, that is: 800 watts x 24 hr/day x 30 day/month = 576000 watt-hours per month or 576 kW-hrs per month. US average is 10¢ per kW-hour 576 kW-hrs per month x 10¢ per kW-hour = $58 per month. 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. To 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. In Brazil, Mexico and China per person use is just 500 kWh, but growth is very different. In Brazil residential use per person has been stable over the last 20 years, whereas in Mexico it is up 50% and in China it has increased 600%. Our household electricity use has been 2,000 kWh each of the last few years, which means it is about 700 kWh per person. We benefit from not using electricity for heating or cooling, although our electric oven is a big source of demand. We have 4 people at home right now and we use on average 100 kwh. The cost for solar panels for a regular rambler house is between $26,000 and $30,000 depending on your usage. These $$ amonts calculated using 100 kwh of electricity and 177 kwh of wood. Just look at your electric bill. It is measured in kwh (1000 watts per hour) if you use 500 watts per day, you will consume 1 kwh in 2 days. If you use 2000 watts per day you will consume 1 kwh in 12 hours. Ovens and microwaves generally consume the most energy, converting that energy into heat How much energy does a person use in a year? In 2011, total energy use per person (or per capita consumption) in the United States was about 313 million British thermal units (Btu). The world per capita consumption of energy 1 in 2011 was about 75 million Btu.  Depending on whether a state is hot or cold, urban or rural, an average household can use as little as 531 kWh a month (Maine) or as much as 1,245 kWh (Louisiana). Costs vary state-by-state, too. Hawaiians pay the most for electricity ($203 a month) and New Mexicans pay the least ($75 a month). But there’s another value listed: how much energy you actually used. If you are a perfectly average American living in a perfectly average household, your monthly electricity bill will read 903 kilowatt hours (kWh), which costs $107, per household. But most of us don’t live in perfectly average households. How much electricity does an American home use? In 2013, the average annual electricity consumption for a U.S. residential utility customer was 10,908 kilowatthours (kWh), an average of 909 kWh per month. Louisiana had the highest annual consumption at 15,270 kWh, and Hawaii had the lowest at 6,176 kWh.  An hour is just 3600 seconds so a Watt hour is simply 1 Watt (Or 1 Joule per second) for 3600 seconds which equals 3600 Joules. 1 kWh is 3600,000 joules and 1 kW is 1000 joules per second. Now that's out of the way, we basically have three different ways of measuring energy usage per person. 1. The energy they produce in their muscles. 2. To 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.
