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.
The average power requirement for the US can be calculated by dividing the total annual energy consumption by the number of seconds in a year. The total number of seconds in a year is approximately 31,557,600. Therefore, the average power requirement for the US would be 0.67 watts (21020 joules / 31,557,600 seconds).
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
It varies depending on the energy consumption habits of each person, but on average, an individual in the United States uses about 230 million BTUs of fossil fuel energy per year, which is roughly equivalent to 70,000 kilowatt-hours or 760 million joules. It is essential to reduce this energy consumption and transition to more sustainable energy sources to mitigate climate change and reduce our carbon footprint.
Nice example !2,000 KWh per month = 2,000 x 12 = 24,000 KWh per year = 24,000 x 3,600 = 86,400,000 KW-sec per year= 86,400,000,000 joules per yearE = m c2m = E / c2 = 8.64 x 1010 / (3 x 108)2 = (8.64 / 9) x 10-6 =9.6 x 10-7kilogram0.00096 gramStill incredible !
If you catch on spark of a lightning bolt, it can give electricity to the world for a year.
100 - 200 a week
9,460,800,000,000 km
For an adult man 2500 kilocalories, for a woman 2000. That is 10,500 or 8400 kiloJoules (4.2 Joules per calorie)
Between 1,000 and 2,500 kilo calories a day.
Joules Clothing carries all types of clothing for people of all age types. All seasons of the year have been considered, so anyone can find what they need for the perfect time.
Watts = joules / secondYou need to divide the total annual energy consumption by the number of seconds in a year (which is about 31.5 million).
calories are an measurement of energy, how long it takes water to be heated to a certain degree. kilograms are a measurement of weight grams > kilograms calories > Calories
150 kilo liter
6000 kilo watts
K is short for Kilo. And Kilo equals one thousand. So 115K per annum equals $115,000 a year
For a specific answer, you need to ask about a specific year.
