electric energy
Light , which is useful Heat , which is NOT useful.
Electricity is the source of energy in a light bulb.
Light bulbs convert energy to light. This conversion is inefficient, meaning that not all of the energy will convert to light because of the design of the bulb and the laws of physics. The energy that does not become light is released as heat, and that's why a light bulb gets hot.
A light bulb uses electrical energy, and produces light, as well as heat.

More technically, the energy is released.
Compared to other types of light-bulb, energy-saving light bulbs will create less heat. This is because any wasted energy is converted to heat.
Energy that is not released as light is released as heat and other EM band radiation.
In a light bulb, electrical energy is transformed into light energy and heat energy.
Electricity is the source of energy in a light bulb.
Most of the energy in a light bulb is heat energy.

light and heat energy occur in a light bulb when it is turned on.
