The law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. In the case of a closed system, the principle says that the

Energy is the quantitative property that is transferred to a body or to a physical system, recognizable in the capacity to do work and in the form of heat and light. Energy is a conserved quantity—the

A plasma globe using electrical energy to create plasma, light, heat, movement, and a faint sound
In a typical lightning strike, 500 megajoules of electric potential energy is converted into the same amount of energy in other forms, mostly light energy, sound energy, and thermal energy.
Thermal energy is energy of microscopic constituents of matter, which may include both kinetic and potential energy.
