If you're talking about nutrition, potatoes are full of starch, which is a complex carbohydrate. if you are talking about how it obtains its energy, then it goes through photosynthesis like any other plant. If you are talking about literal energy, then it would store potential energy until something else caused it to move, which would then be kinetic energy.
Turbines spin generators that produce electrical energy.
Water and rain
A firecracker uses chemical energy to produce the light and sound.
Fireworks uses chemical energy. They produce heat and light energy.
Nuclear fusion is the process that occurs in the sun that produces energy. Hydrogen atoms are fused together to produce helium. As a result of that fusion, energy is released in the form of heat and light.
Calories don't "produce" energy; calories are a UNIT OF ENERGY.
Computers do not produce energy, they use/consume energy.
The sun produce light and nuclear energy
