They reflect light.
energy
Brown dwarfs are heated primarily due to the compression of their interiors and are hot enough to glow. Some the the more massive brown dwarfs may also fuse deuterium, an isotope of hydrogen, for a short period after they form.
Yes but not in the way you are thinking. The Moon reflects light but does not produce it's own energy.
Chemical energy is converted into electromagnetic energy in the form of light.
False. Low heat light bulbs can produce the same amount of light, and also save on energy.
No. That is why they are called black dwarfs. See related question
The sun produce light and nuclear energy
Chemical energy will produce the light in a firefly, or in a hand-held glow tube. Electrical energy will produce the light in a light bulb. Heating something up to a high enough temperature will produce light. Burning a material may produce light.
Flashlight produce light energy and heat after turning on.
No, a toaster does not produce light energy. Toaster heats up bread using electrical energy which is converted to heat energy for the toasting process.
energy
The capacity to do work is energy. The capacity to produce light is luminosity.
This type of energy is called current electricity

Leaves appear lighter in the sun than in the shade due to the process of photosynthesis. In the presence of sunlight, chlorophyll in leaves absorbs light energy to produce sugar, which can make the leaves appear brighter.
