Answer: Nuclear energy ⇒ Heat ⇒ Kinetic energy ⇒ Electrical energy
Explanation
Law of conservation of energy states that energy can neither be created nor destroyed. It can convert from one form to another. The energy delivered at our home via electrical wall outlet was not present in the same form in the beginning.
In the power plant, the nuclear energy converted to heat. This heat runs the turbine where energy is converted to kinetic energy. This kinetic energy runs the generator which converts the energy to electrical energy which transported to our homes.
