A body giving out light continually radiates energy. Light waves are electromagnetic waves which propagate by time varying electric and magnetic field. As energy is associated with both these fields so light also carries energy. Besides to produce these fields a body(say an electron) has to do work and the body's energy decreases. This energy is carried by light waves.

Electrical energy and light energy are useful to me in a variety of ways from the machines used to make the food you eat to the energy used to purify the water you drink. The clothes you wear are even dyed different colors from the light energy alone.
Light energy is transformed into chemical energy
