Energy is released in the form of radiation. For an electron to move from a lower shell to a higher one, energy must be put in. This means that going from a higher shell to a lower one, it must lose energy to be in a less excited state. The electron must emit this radiation in the form of light with a wavelength equivalent to the amount of energy put in.
