Energy Vocabulary – What Does ‘Eergy’ Mean?

The world we live in is made up mostly of energy. Most of the things that we do every day – from cooking our food to walking to operating machines involve some kind of energy transfer. In order to understand this concept, it’s important to understand what energy actually is and how it can be used. We must also have a basic knowledge of the different kinds of energy, their characteristics, and how they are transferred. All types of energy are related to motion.

For instance, any body that has mass has kinetic energy, whether it’s in motion or not. A spring, while at rest, contains kinetic energy due to its configuration; it has potential energy since its design is able to generate motion, because a tensioned spring contains a potential energy gradient. A semi conductor, like a wire, is an example of a nonrenewable material, because it has no potential energy of its own. When the wire is heated, some of its electrons will jump to another part of the wire, and therefore, it generates some kind of electricity. The more electrons that jump, the more electricity generated by the wire.

The different types of energy can be described by their specific characteristics. Kinetic energy is the force that propels an object. It can be defined as the amount of energy needed to move the object with a particular speed. Potential energy is the amount of energy needed to make the object move with that speed. And, thermal energy describes the amount of energy needed to warm up a body or to cool a body.

Now, there are two different forms of electromagnetic energy: electromagnetic light, and sound. Light comes in three varieties, visible, ultraviolet, and infrared. Electromagnetic energy is the most common form and is found everywhere in our environment. Some kinds of electromagnetic energy are in the form of x-rays, gamma rays, sound, and waves.

One of the most interesting forms of electromagnetic energy, however, is sound energy. Sound is produced when something vibrates, such as the air being moved across a bridge. There are three basic kinds of sound, each having differing uses, but all forms have the same basic principle.

Let’s take the last type of renewable energy source, which is biomass energy. Biomass energy is created from living things. Some examples include wood, waste, and agricultural products. Wood and waste can be burned, while agricultural products must be turned into something else before they can be used. They also have to be harvested before they can be used. A biomass energy system involves converting biomass to energy, and storing the energy in energy cells.
