Energy is a fundamental concept in both physics and everyday life, describing the capacity to perform work or produce change. It exists in various forms that can be categorized as either kinetic (movement energy) or potential (stored energy). Common types include mechanical, thermal, electrical, chemical, nuclear, and radiant (light) energy. Energy is conserved in isolated systems, meaning it cannot be created or destroyed but only transformed from one form to another. This principle is central to the laws of thermodynamics, which influence everything from biological processes to the technologies powering modern society. Additionally, the concept of energy efficiency—using less energy to perform the same task—is crucial in efforts to manage resources and mitigate environmental impacts. Renewable energy sources like solar, wind, and hydroelectric power are increasingly important due to their potential for sustainable use without depleting resources.
