it's because people sometimes run a lot and waste their body energy
Energy is often wasted in the form of heat during transfer. This occurs due to inefficiencies in the conversion process, where some energy is lost as heat instead of being used for the intended purpose.
Yes, friction can produce heat energy when two surfaces rub against each other, causing resistance. The kinetic energy of the moving objects is converted into thermal energy due to the frictional force generated between them.
Heat is a form of energy that is transferred between objects or systems due to a temperature difference. When heat is transferred, it can increase the internal energy of an object, causing its particles to move faster and creating a rise in temperature. In this way, heat and energy are closely related as heat is a way in which energy can be transferred between objects.
The primary way heat is transferred through a gas is by conduction, where kinetic energy is transferred from one particle to another through direct contact.
Heat can be transferred in an iron rod through conduction, where vibrations of atoms/molecules pass thermal energy along the rod. However, in a vacuum, heat cannot be transferred in the same way due to the absence of particles to transfer thermal energy.

Outside the homes, electricity is transferred at several thousand volts, for reasons of efficiency (less energy is wasted that way). This voltage is far too high for home use. (Also, home devices are set up for a specific voltage.)Outside the homes, electricity is transferred at several thousand volts, for reasons of efficiency (less energy is wasted that way).

Wasted energy will increase the amount of useless, or unusable, energy, and reduce the amount of usable energy in the Universe. The wasted energy is related to entropy - one way to express the Second Law of Thermodynamics is to say that there are irreversible processes (in terms of energy), another is that "entropy increases". However, entropy is not energy; it is not measured in Joule, but in Joule/Kelvin. In any case, you might say that when energy is wasted, entropy increases.Wasted energy will increase the amount of useless, or unusable, energy, and reduce the amount of usable energy in the Universe.

Time would be considered wasted because once it is wasted, there is no possible way to get that time back. That is why time is the most valuable thing we have.

Seems that nature works that way. Lots of ingenious methods have been devised (like Maxwell's Demon, for example), but in the end, none of them works.Basically, wasted energy, or unusable energy, is energy that is not concentrated in one place, but scattered. Apparently, it takes MORE energy to gather this, than what you get.
