Chemical >>> Electrical
In most energy transformations, part of the energy is wasted. Much of the wasted energy is usually converted to heat.
The byproduct of energy transformations is heat, which is released into the environment. This is due to the second law of thermodynamics, which states that some energy will always be converted into an unusable form (in this case, heat) during energy transformations.
Electrical energy to kinetic energy
from electrical energy to mechanical energy
Kinetic and potential energy are common types of energy involved in energy transformations. Kinetic energy is associated with the motion of objects, while potential energy is associated with the position or state of an object. These energies can be converted from one form to another during energy transformations.
There are a few energy transformations when a gun is fired. Some of these include potential to kinetic energy, chemical to mechanical energy, and chemical to electromagnetic energy.
During energy transformations, energy is never created or destroyed, but it can change from one form to another (e.g., thermal to mechanical).

Thermodynamics
The "all day" efficiency of a transformer is defined as the ratio of energy out/energy in for a given all day cycle.
