    Different Types of Energy With Everyday Examples

    By Jennifer Betts, B.A. , Staff Writer

    What do turning on a light switch and running a mile have in common? Both activities require energy. Energy is the ability to do work, and the types of energy used depend on the object doing the work. So what are the different types of energy? Keep reading for the 10 different types of energy in the physical world, divided into potential and kinetic forms.

    Types of Potential Energy

    When energy is stored in an object, it has the potential to be used. That's why it's called potential energy. Think about a runner waiting at the starting line of a race. The tension in their muscles is potential energy before the whistle blows to start the race. There are two main types of potential energy, though each type of energy has a potential form.


    Gravitational Potential Energy

    When an object is held in a vertical position, it has gravitational potential energy. The amount of energy it's storing has to do with the object's mass and how high it is. Heavier objects have more potential energy, as do objects that are higher. Examples of gravitational energy include:

    a book on the edge of a desk

    a skier at the top of a hill

    a ripe apple about to fall from a tree

    If you drop a small rock into a lake, it will make a smaller splash than if you drop a large rock. That's because the heavier rock has more gravitational potential energy.

    Elastic Potential Energy

    Elastic potential energy is stored in materials that are made to stretch, such as rubber. Items with springs also hold elastic potential energy. The stretchier (or springier) the item, the more energy it can store, and the more it will stretch or bounce. Some examples of elastic potential energy are:

    a person jumping on a trampoline

    an archer stretching an arrow on a bow

    a balloon holding air

    All of these examples allow elastic materials and springs to hold potential energy. When they release the energy, it becomes kinetic.


    Types of Kinetic Energy

    Potential energy converts to kinetic energy when it's released. The energy held in the springs of a trampoline, for example, converts to mechanical energy when the trampoline bounces someone up high. However, there are other forms of kinetic energy that you see in your everyday life.

    Mechanical Energy

    When you see motion, mechanical energy is at play. It uses potential energy stored in an item to create movement. Objects using mechanical energy can also move thanks to conversion from other types of energy. Examples of mechanical energy you see every day include:

    driving a car hammering a nail riding a bike

    Electrical Energy

    Electrical energy comes from electric charges. We channel the energy from these charges in wires and electrical cords in order to use them to light up our house. Examples of electrical energy in your everyday life include:

    static from rubbing a balloon on your hair

    turning on a light switch

    charging your cell phone


    Chemical Energy

    Chemical energy is the energy released when chemical bonds form or break like in chemical reactions. You aren't likely to see this type of energy on the molecular level, but you can see it in the following examples:

    burning wood in a bonfire

    using batteries for electricity

    digesting food

    Nuclear Energy

    Nuclear energy typically brings about images of atom bombs and nuclear power plants. It occurs when atoms fuse (fusion) or split (fission). It is used to heat houses or destroy whole landmasses. Examples of nuclear energy include:

    nuclear plants producing electricity

    an atomic bomb fission on the sun

    Electromagnetic Energy

    Electromagnetic energy carries light energy on electromagnetic waves. That makes electromagnetic energy one of the only types of energy seen with the human eye. Examples of light from electromagnetic energy include:

    burning a candle

    flipping a light switch

    turning on a flashlight


    Radiant Energy

    The sun is a source of nuclear energy and light energy, but it's also a great source of radiant energy! Radiant energy is a type of energy that creates heat and light. Other examples of radiant energy besides the sun include:

    energy produced by a microwave

    infrared lamps X-ray machines

    Thermal Energy

    Thermal energy keeps you warm. Also called heat energy, radiant energy gives off heat and has three types: convection, conduction, and radiation. Examples of thermal energy include:

    a cake baking in the oven

    heat from an electric heater

    a cup of hot cocoa

    Sound Energy

    Sound energy is an easy one because you hear it. When vibrations create sound energy, it goes to your ear and is translated by your brain into the strumming of a guitar or call of your mother’s voice. Additional examples of sound energy include:

    ry to think of something that doesn't involve energy and you won't get very far. Even thinking—even thinking about energy!—needs some energy to make it happen. In fact, everything that happens in the world uses energy of one kind or another. But what exactly is energy?

    Energy is a bit of a mystery. Most of the time we can't see it, yet it is everywhere around us. Revving car engines burn energy, hot cups of coffee hold energy, street lights that shine at night are using energy, sleeping dogs are using energy too—absolutely everything you can think of is using energy in one way or another. Energy is a magical thing that makes other things happen. Everything in the world is either energy or matter ("stuff" around us) and even matter, when you really get down to it, is a kind of energy!

    Picture: A supernova is the remains of an exploding star and it's just about the most spectacular release of energy you can get. This particular one is a gigantic explosion of dusty gas 14 light-years across (roughly 132 billion kilometers) and booming outward at 2,000 km per second (or 4 million mph).

    Potential energy and kinetic energy

    Although there are many kinds of energy in the world, they all fall into two broad categories: potential energy and kinetic energy. When energy is stored up and waiting to do things, we call it potential energy; "potential" simply means the energy has the ability to do something useful later on. When stored energy is being used to do something, we call it kinetic energy; "kinetic" means movement and, generally, when stored energy is being used up, it is making things move or happen.

    It's easy to find examples of both potential energy and kinetic energy in the world around us. If you push a boulder up a hill, you'll find it's a real effort to get to the top. This is because the force of gravity is constantly trying to pull you (and the boulder) back down. In science, we say you have to do work against the force of gravity to push the boulder up the hill. Doing work means you have to use energy: the muscles in your body have to convert sugar and fat to make the energy you need to push the boulder. Where does this energy go? Although you use energy as you climb, your body and the boulder also gain energy—potential energy. When the boulder is at the top of the hill, you can let it go so it rolls back down again. It can roll down because it has stored potential energy. In other words, it has the potential to roll down the hill all by itself.

    Artwork: You have to "do work" against the force of gravity when you push a boulder up a hill and lose energy as you do so; the boulder gains this "potential" energy as it climbs.

    As the boulder starts to roll down the hill, the potential energy it had at the top is gradually converted into kinetic energy. When we talk about kinetic energy, we usually mean the energy something has because it is moving. Anything that has mass (contains some matter that takes up a volume) and moves along at a certain velocity (or speed) has kinetic energy. The more mass something has and the faster it goes (the higher the velocity), the more kinetic energy it has. If a truck and a car are driving parallel to one another down the freeway, at the same speed, the truck has more kinetic energy than the car because it has much more mass. (Read more about the science of motion.)

    A lot of things we do each day involve converting energy between potential and kinetic. Pull yourself up a cliff on a rope and you have more potential energy the higher you go up. If you abseil down, your potential energy is converted into kinetic energy as you move. By the time you reach the bottom, the kinetic energy has turned to heat (your climbing equipment and the rope will get surprisingly hot) and sound (the rope will make a noise as you whiz down).

    Artwork: You gain potential energy every time you walk up stairs. Your muscles pull your body against the force of gravity, doing work. In theory, the potential energy your body gains as you climb is exactly the same as the food energy it loses: one form of energy is simply converted into another. (In practice, you need to use more energy than you might think because your body wastes quite a lot of energy in the process.) At the top of a flight of stairs, you could turn your stored potential energy back into kinetic energy (movement) in various ways, such as sliding down the banisters or jumping down a fireman's pole! You can trace every bit of energy your body uses back to the food you eat, which comes from animals and plants and ultimately from the Sun.

    The Different Uses of Energy in our Daily lives

    By Jack Dawson - 12.28.2015 Facebook Twitter Linkedin

    When we talk about energy saving, most of you remember being care free children at home and the adults being in a constant need to urge you to switch off the lights or the television or the washing machine. Now that you are an adult, you understand why it was important to actually do things such as switching off the lights when you leave a room.

    Energy saving has been an elusive quest for many of us living in urban developed cities. We need energy for everything in our household and it is one of the earmarks of modern living and convenience. We use energy for everything in the home and in the office and basically to perform daily tasks.

    Energy use can be divided many dfferent ways but the most common is through the the end product — either electricity; themal energy, which is heating/cooling (including hot water); or transportation. You can also break down energy into its end-users, which are described below.

    Residential uses of energy

    When we talk about residential uses of energy, these are the most basic uses of energy. They include watching television, washing clothes, heating and lighting the home, taking a shower, working from home on your laptop or computer, running appliances and cooking. Residential uses of energy account for almost forty percent of total energy use globally.

    Waste in this category of use is also the highest globally. This can be attributed to the lack of education offered to the public on how to conserve the energy they use daily, or to the lack of energy conseration products available in the market. Most people are ignorant to the fact that there are avenues or companies and innovations available that can help them monitor and reduce the amount of energy they use.

    Commercial use of energy is what energy is used for in the commercial sector. This includes heating, cooling and lighting of commercial buildings and spaces, power used by companies and business throughout our cities for computers, fax machines, workstations, copiers just to name but a few.

    The uses of energy in the commercial space is more or less similar to the uses in the industrial space save for personal uses. Energy saving here though, is targeted at the corporate world rather than at individuals. Players in the sector of energy conservation should introduce energy saving campaigns in order to curb the culture of waste present at our places of work.

    Transportation is one hundred percent dependent on energy. Over seventy percent of petroleum used goes into the transport sector. The transport sector includes all vehicles from personal cars to trucks to buses and motorcycles. It also includes aircrafts, trains, ship and pipelines.

    The transportation sector can be very vital in the overall quest for energy conservation. Innovations such as the introduction of more fuel efficient vehicles and development of alternative sources of energy for our transport system can greatly help in the saving of energy

    Efforts at energy conservation can be made on a global scale if we factor in the uses and deal with them one by one. If we focus on them as individual uses rather than trying to find a solution as a whole, we will make much bigger strides in conservation.
