A windmill captures 300W of wind power for 9h. The kinetic energy is converted to electric energy and stored in a battery, before being used by a 60W light bulb. During the process 78% of the energy is lost. wind energy captured: Wh loss: Wh energy delivered to light bulb: Wh How long could the light bulb be used? hours
