Energy conservation means reducing energy use.
In the scientific sense, the term energy conservation refers to the Physics Principle which states that the total energy of the universe is constant for any closed system. In this way, energy can only change shape: kinetic energy becomes potential energy, potential energy becomes kinetic energy, internal energy becomes heat or work. Thus energy cannot be created or destroyed, only transformed.
In the technical terminology of the Engineering area, the term energy conservation refers to techniques and procedures aimed at reducing waste and inefficient use of energy, especially electrical energy, without compromising comfort and / or production. In general, the term conservation is linked to the rational use of energy. That is, energy conservation means reducing energy use.
