SUMMARY
The average energy requirement for an individual performing normal activities is approximately 2,000 kilocalories per day, which translates to about 8.4 megajoules or 2.3 kilowatt-hours (kWh). A typical human burns energy at a rate of approximately 100 watts, leading to a total daily energy consumption of around 2.4 kWh. This discussion clarifies the conversion between food calories and electrical energy, emphasizing that a food calorie is equivalent to a kilocalorie.
