Given the amount of work or occupational engagements of man on daily basis, the energy humans produce per day assuredly as its own figure when compared to what other creatures dispense in order to efficiently attend to or take care of their daily activities.
Although the result of the proportion of energy produced per day may vary depending on the kinds of food and nutrients consumed every day by individual men. What also distinguishes the result is the cumbersomeness of the work, whether the man is lazy or diligent has probably nothing to do with the regular energy production or power dispensation of the human being.
Human power is work or energy that is produced from the human body. It can also refer to the power (rate of work per time) of a human. Power comes primarily from muscles, but body heat is also used to do work like warming shelters, food, or other humans.
The Energy Humans Produce Per Day
Humans get their energy from the consumption of food they make per day. Each kilocalorie (kcal) we ingest is tantamount to 4.184 kilojoules (4×103J) of energy. Just imagine an average calorie intake of 2000 per person and almost 8 billion inhabitants on planet earth, we process a staggering 58.58 petajoules (59×1015 J) of energy each day and 21.38 exajoules (21×1018J) per year.
However, these numbers are only a fraction of the estimated global consumption in primary energy of ca. 500-1000 exajoules per year. That means even if we could harvest 100% of the energy we produce, we could not satisfy the global demand.

The conversion of energy is always subjected to losses. For the human body, these losses are mostly thermal, in form of body heat. Thus, we need to discuss the energy humans produce per day. Check the information below:
Most people spend about 10,000 kilojoules amount of energy per day or about constant of 110 watts for 24 hours. The human body is super efficient, it can produce 99% of energy that it gets from food. If you eat 2,000 calories of food, it will produce 1,980 calories of energy.
The average human, at rest, produces around 100 watts of power. Over periods of a few minutes, humans can comfortably sustain 300-400 watts; and in the case of very short bursts of energy, such as sprinting, some humans can output over 2,000 watts.
The bulk of this energy is required for important tasks, such as pumping your heart and flexing your muscles, but a lot of it is wasted, primarily as heat.
