Leaving one light bulb on unnecessarily can waste a significant amount of energy over time. The exact amount depends on the type of bulb (incandescent, LED, etc.) and its wattage. However, generally speaking, it is more energy-efficient to turn off lights when they are not needed to help reduce energy waste.
The light bulb uses electrical energy, and produces light, as well as waste heat. The act of turning it on in itself uses a small amount of energy stored in your muscles.
Light has heat and light energy. Example is bulb.

Light bulb??
Light energy is stored in a bulb when it is switched off. When the bulb is turned on, electrical energy is converted into light energy and heat.
To plug it in, you use your muscle energy. When current flows through the bulb,electrical energy converted to the heat and light energy in the bulb.
A light bulb produces radiant energy in the form of visible light. When electricity flows through the filament of a light bulb, it heats up and emits light.
An electric light bulb converts electrical energy into thermal energy which is in the form of radiated light and heat. For example, the " easy bake oven" uses a light bulb to cook the food.
The type of energy that makes a light bulb feel warm is heat energy. This energy is generated as a byproduct of the light bulb's operation and is emitted in the form of infrared radiation, which can be felt as warmth.
It means that a light bulb converts one type of energy to a different type of energy.
Electrical energy is transferred into light energy, however if the light bulb is an older one, some energy will also be transferred into heat loss.
