Energy is lost through Heat; which is used to obtain & digest food, excrete waste, and maintain body temperature.
Energy is lost through waste energy, or energy that is not required for the action or device. For example a hair dryer is needed for heat. It also gives out sound energy. This energy is wasted.

Energy can be lost in various ways, such as through heat transfer, friction, air resistance, and inefficient energy conversions. Whenever energy is transformed from one form to another, there is typically some energy lost in the process due to these factors.
The question is a little vague perhaps to make a very helpful answer. However, a very relevant example is to explain why if you push a cardboard box on a carpet why it doesn't just keep moving. The friction that is caused by the surface of the carpet and box cause the box to slow down and the energy that is lost (that you originally put into it by pushing it) is lost to heat that heats both the box and the carpet. Loss to heat is the most common form of energy loss.
Potential energy can not be lost, it is only transformed into kinetic energy. This is stated in the Law of Conservation of Energy.
To calculate the amount of energy lost in a system, you can use the formula: Energy lost Initial energy - Final energy. This means subtracting the final energy from the initial energy to find the difference, which represents the amount of energy lost.
The energy lost formula used to calculate the amount of energy dissipated in a system is: Energy Lost Initial Energy - Final Energy.
Lost energy in energy systems is often in the form of waste heat energy. This is energy that is not converted to useful work and is typically released into the environment, resulting in a loss of efficiency in the system. Strategies such as improved insulation, energy recovery systems, and better design can help reduce this lost energy.
People think objects have lost energy when they slow down because kinetic energy, which is the energy of motion, decreases as the object slows down. This lost energy is usually transformed into other forms of energy, such as heat or sound, through the process of friction or air resistance.
is lost as heat due to inefficiencies in the process.
