Energy in Everyday Life – Basic Principles
How it works
Energy is the ability to do work, give off heat, or produce light. Energy occurs in different forms, e.g. as kinetic energy, potential energy, thermal energy, electrical energy, or chemical energy. In everyday life we encounter energy everywhere: when heating, cooking, driving a car, or doing sport. Energy can be converted from one form into another, but it cannot be destroyed (conservation of energy). Energy sources are, e.g., the sun, food, or fuels; electrical energy is provided, e.g., via sockets, batteries, or rechargeable batteries. Devices and machines need energy in order to function. Saving energy is important for the environment and for costs.
Energy can take on different forms and is constantly converted in everyday life. It cannot be created or destroyed, only converted (conservation of energy).
