A light bulb uses electricity as its source of energy.
A light bulb to uses electrical energy which is supplied to a resistor that gives off heat as well as light. The resistor is a thin coiled piece of wire made of Tungsten because it has the highest melting point of any metal.

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.

No. The incandescent bulb uses electrical energy and the light stick uses chemical energy.
No. A light bulb can only USE energy, it cannot STORE it. Before it can operate it needs to be given a supply of electrical energy and, from that input of energy, it produces outputs of energy in the form of heat and light.
A compound microscope uses light energy because they have a light source at the bottom

For most light bulbs, they consume equal amounts of energy regardless of bright or dark environments. This is because a light bulb is simply lit up by a power source, and is unable to control brightness, producing the same amount of light. That is why most people say we should not waste energy by switching on a light bulb in the day.

No. The incandescent bulb uses electrical energy and the light stick uses chemical energy.
Photoautotrophs use light as the energy source for producing proteins, lipids and other organic substances. Examples of photoautotrophs are plants.
No a light bulb does not use chemical energy. Even though it uses the chemical mercury to create light. Hope this helps =)

They are the same light bulb, so they are the same. The colored bulb has coloring applies on its outside surface. They do not make energy, they use energy.
Energy efficient light bulb saves half of energy consumed by a regular bulb, although it has a lower range light compare to the high energy consumer bulbs.
No. A light bulb can only USE energy, it cannot STORE it. Before it can operate it needs to be given a supply of electrical energy and, from that input of energy, it produces outputs of energy in the form of heat and light.
If you mean could you use the light from a bulb to energize a solar array or photovoltaic cell, the answer is yes. However the energy to run the bulb would exceed the energy produced by the array so you would have a net loss of energy in such a system.
No, light is not a source of energy at all. Light is something we make with energy. We use water, wind, solar power, coal, natural gas or oil to create electricity which we use to make light.
