Definition and Types of Energy
Energy is derived from the ancient Greek words “active” (“en”) and “work” (“ergon”), signifying “convertible to work” Ref . Fundamentally, energy refers to the capacity to perform work. It exists in various forms such as chemical, light, fossil, and electrical energy, all of which can be converted into one another. According to the Law of Conservation of Energy, energy cannot be created or destroyed but only transformed, maintaining a balance in a closed system Ref .
