Electrical energy can be converted to light. In addition, nuclear energy as in a nuclear weapon will give off a blinding flash of light. Also, using fireflies as an example, chemical reactions can also give off light energy.

LED lights
Turning off lights saves energy by reducing the amount of electricity consumed. When a light is on, it continuously draws power from the electrical grid, using more energy the longer it is left on. By turning off lights when they are not needed, less electricity is used, leading to lower energy consumption and a decrease in utility costs.
A piano gives off sound energy when it is played
Currently, LEDs (light emitting diodes) are the lowest energy consumption lights. Unfortunately, they are harder to manufacture and therefore are more expensive that traditional lights.
Electrical energy.
electric energy
Turning off unused lights reduces energy consumption, which falls under the category of energy efficiency. Energy efficiency aims to decrease the amount of energy used for a given task without sacrificing performance or comfort.

A reaction that gives off energy
A toaster gives off thermal energy, which is the energy associated with heat. When the toaster is turned on, electrical energy is converted into heat energy to toast the bread.
