A light bulb uses energy. It uses electricity.
When the bulb is lit it uses energy. When there is no bulb, no energy is used even if it is switched on.
This depends on how long it is being used. The 60 Watt bulb consumes 2.6667 times the power of an 18 Watt bulb, but energy equals power times time. There is also an amount of 'hidden' energy: the energy to manufacture and transport the bulb. This depends on how long it is being used.

More watts means it uses more energy per second (watt is a unit of power). If it is a light-bulb of the same type of technology, the higher-watt light bulb would also give off more light.
Every person has a different power of light bulb. In my room, I have a 7.5 and a whole bunch of 60s. The number of watts you choose for your light bulb depends on how bright you want your light to be. The higher the number, the brighter it is.
NopeNo, potential energy would be, for instance, a spring that is compressed. It could cause motion if released. It is stored energy. The light bulb uses electrical energy, which it converts to light and heat energy. potential energy is like when you wind up a torch or a radio

A light bulb uses energy. It uses electricity.
A light bulb uses electrical energy, and produces light, as well as heat.
A light bulb typically uses electrical energy to produce light. The electrical energy is converted into heat and light energy by the filament inside the bulb.
It uses less energy to produce the same amount of illumination as a standard light bulb
incandescent

No, a light bulb does not convert light into chemical energy. A light bulb works by converting electrical energy into light energy and heat energy through the process of electrical resistance in the filament.
When the bulb is lit it uses energy. When there is no bulb, no energy is used even if it is switched on.

The job of a light bulb is to convert electrical energy into visible light energy. (Not ALL of the electrical energy a bulb uses is converted to light energy. Their efficiency is quite low. An incandescent light bulb is more efficient as a heater than as a source of visible light. Fortunately, our eyes are very sensitive.)
