Introduction to energy storage

This is defined in Eq. (1), where the total energy transferred into ( Ein) or out of ( Eout) the system must equal to the change in total energy of the system (Δ Esystem) during a process. This indicates that energy cannot be created nor destroyed, it can only change forms. (1) E in − E out = Δ E system.
