Most of the energy in a light bulb is heat energy.
A light bulb uses electrical energy, and produces light, as well as heat.
light and heat energy occur in a light bulb when it is turned on.
No. An energy saving light bulb is just a light bulb, and can't charge anything. The reason it's called an "energy saving" device is that it can give you the same amount of light while using less electrical energy than older bulbs used.
In a light bulb, electrical energy is transformed into light energy and heat energy.
A light bulb is not an example of electromagnetic energy, but the light which the bulb gives off is an example of electromagnetic energy.
