How many types of engry are there?

There are several types of energy, but they can broadly be categorized into two main forms: potential energy, which is stored energy based on an object's position or state, and kinetic energy, which is the energy of motion. Within these categories, there are various specific types, including thermal, chemical, electrical, nuclear, and mechanical energy, among others. Each type of energy can be transformed into others, following the laws of thermodynamics.
