Human power is the rate of 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.

Useful output energy is always lower than input energy. Efficiency of power plants, world total, 2008. Energy conversion efficiency (η) is the ratio between the useful output of an energy conversion machine and the input, in energy terms. The input, as well as the useful output may be chemical, electric power, mechanical work, light (radiation ...
According to the French energy and environment agency ADEME, [65] an average motor car has an embodied energy content of 20,800 kWh and an average electric vehicle amounts to 34,700 kWh. The electric car requires nearly twice as much energy to produce, primarily due to the large amount of mining and purification necessary for the rare earth ...
The amount of range gained per time charging, charging speed, is the ratio of charging power to the vehicle's consumption, and its inverse is the charging time per driven distance: C h a r g i n g s p e e d [ k m / h ] ≡ c h a r g i n g p o w e r [ k W ] c o n s u m p t i o n [ k W h / k m ] {\displaystyle Charging\ speed\ [km/h]\equiv {\frac ...

As the U.S. faces a mid-June heat wave, here's what to know about heat exhaustion and heat stroke—and how to stay safe.
As in other mammals, human thermoregulation is an important aspect of homeostasis. In thermoregulation, body heat is generated mostly in the deep organs, especially the liver, brain, and heart, and in contraction of skeletal muscles. [1] Humans have been able to adapt to a great diversity of climates, including hot humid and hot arid.
