Base on a calorie calculator site, a 12 year old boy would need 1800 - 2200 kCal of energy from food and is 7560 - 9240 kJ per day.
A typical nuclear plant can run continously at 600 MW, which 6 x 108 Joules per second or, per day, 5.184 x 1013 Joules.
Rate of energy= 69.4 watts.
The power of a 150-megawatt wind turbine is 150 megawatts,or 150 million watts.The energy it generates is 150 million joules per second, or 150 thousand kilowatt-hours per hour.1 day = 86,400 seconds1 year = 365 days (rounded)150 million joules per second = (150 million x 86,400) joules per day =(150 million x 86,400 x 365) joules per year =4.7304 x 1015 joulesof energy per year (4,730,400,000,000,000 joules of energy per year)If we convert this number to the more familiar unit that appearson your electric bill, it's equal to1,314 million Kilowatt-hours of energy per year
The watt is a rate of delivery or use of energy (1 Joule per second) Anything called watts per day means an increase in power per day. (100 watts first day, 200 watts second day, 300 watts third day etc). I'm sure you don't mean that. Direct ("normal" ) sunlight that falls on a square metre is up to about 100 Watts so you'll never get more power from that even with 100% efficiency. Consult the brochures. Probably a few tens of watts per square meter. Energy per day is watts x time-of-sunlight (direct, near 90 degrees). Which will be Joules. 3600x1000 Joules equal 1 Kilowatt-hour, sometimes called "1 unit".

A kilojoule is about 4.2 times smaller than a calorie. Find the amount of calories you need in a day and multiply that number (e.g 2000) by 4.2.

about 300 calories per day is about a kilo per month. 1 kilo=2.4 lbs 1lb=3600Ca=12 days
The energy required is roughly 3600 seconds/hour x24 hours/day x1 joule/second=86400 joules /day.
