A comprehensive illustrated guide to Energy types. Energy facts and information about different types of energies. Learn about the sources of energy

Energy is Ability to do work.

There are two types of energy Potential Energy and Kinetic Energy. Energy can be created in different forms such as heat, kinetic or mechanical energy, light, potential energy, electrical, or other forms. There are two types of energy - stored (potential) energy and working (kinetic) energy. For example, the food you eat contains chemical energy, and your body stores this energy until you release it when you work or play.

The energy we use every day is divided into two groups, renewable energy which is an energy source that can be used over and over again and non-renewable/ conventional is an energy source which we are using up and cannot recreate in a short period of time.

Different types of energy sources

 

There are 14 different types or sources of energy. The energy types can vary on so many different factors such storage types and different types of groups

Electric energy

Electrical energy is the movement of electrons. Everything is made of tiny particles called atoms. Atoms are made of even smaller particles called electrons, protons, and neutrons. Applying a force can make some of the electrons move. Electrons moving through a wire are called electricity. Lightning is another example of electrical energy

Atomic energy

Nuclear energy is the energy in the nucleus of an atom. Atoms are the smallest particles that can break a material. At the core of each atom there are two types of particles (neutrons and protons) that are held together. Nuclear energy is the energy that holds neutrons and protons. Nuclear energy can be used to produce electricity. This energy can be obtained in two ways: nuclear fusion and nuclear fission. In nuclear fusion, energy is released when atoms are combined or fused together to form a larger atom. The sun produces energy like this. In nuclear fission, atoms are split into smaller atoms, releasing energy. Actually, nuclear power plants can only use nuclear fission to produce electricity.

Kinetic energy

Kinetic energy is the energy of motion, observable as the movement of an object, particle, or set of particles. Any object in motion is using kinetic energy: a person walking, a thrown baseball, a crumb falling from a table, and a charged particle in an electric field are all examples of kinetic energy at work. Objects that are not in motion possess potential energy (the other main type of energy), which is converted to kinetic energy when some force , such as gravity , acts upon the object to set it in motion. Elastic potential energy, for example, is stored in a stretched rubber band; when the rubber band is released, the stored energy is converted to kinetic energy. The word kinetic is derived from the Greek word “kinesis” meaning motion. When an object is moving, it possess a energy and such energy is called kinetic energy. The object includes very large things, like planets, and very small ones, like atoms. Heavier objects moves faster and have more kinetic energy. Kinetic energy may be best understood by examples that demonstrate how it is transformed to and from other forms of energy.

When an object is moving, it possess a energy and such energy is called kinetic energy. 

Light energy

Light is all around us. It has the ability to tan or burn our skins, it can be harnessed to melt metals, or heat our food. Light energy posed a huge challenge for scientist up to the 1950′s. Hopefully, in the future, we will be able to use light energy and solar wind to travel among the stars. Light is a form of energy which our sense of sight can detect. It is made of electro-magnetic radiation and travels in a straight path. In everyday we use the word “light” for at least 10 times a day!! Have you ever think about the energy we get from the light. Light is all around us. It has the ability to tan or burn our skins, it can be harnessed to melt metals, or heat our food. Light energy posed a huge challenge for scientist up to the 1950′s.

Water energy

We can define energy as the ability to do work; energy is used to make movements. Water has energy embedded within it. The water has kinetic energy which is used for all its movements for running down the stream. The water that is not in motion or the stored water has potential energy. This energy is not used by the water directly. This potential energy is converted into kinetic energy and this gets converted into mechanical energy which in turn gets converted to electrical energy. As we all know energy cannot be created it is just the transformation of one form to another, so the stored potential energy is used to produce electricity. This is the major process that happens in all hydroelectric power stations.

 

 

Sun energy 

Since solar energy is found in abundance it is used in wide range of areas and many places rely upon this source of energy. Then arises a question about what will happen during winter days? Is it possible to use solar energy when there is no heat at all? Yes. Even at those times one could use it because the solar panels( through which the solar energy is converted into required form of energy) are capable of storing the energy and saving it for later use. However these solar panels storing energy can’t help out for a large number of days, but can be used when we run out of any energy source.

 

 

Gas energy 

Gas energy is also known as natural gas energy. Natural gas is also a fossil fuel like oil. And it is also a non-renewable energy similar to oil energy because it can’t be replaced in human time-frame. It is formed when plants and animals, which store the solar energy in them, gets buried inside the earth and due to heat and pressure applied over a span of 1000 years. Natural gas is a mixture of hydrocarbon gas. Its main constituent is methane of the alkane family. It also consists of various other higher order alkanes such as ethane, butane and others in varying proportions. It might also consist of small quantities of carbon dioxide, nitrogen and hydrogen sulphide.

 

Geothermal energy

Geothermal energy is thermal energy generated and stored in the Earth. Thermal energy is the energy that determines the temperature of matter. The Geothermal energy of the Earth's crust originates from the original formation of the planet (20%) and from radioactive decay of minerals (80%). The geothermal gradient, which is the difference in temperature between the core of the planet and its surface, drives a continuous conduction of thermal energy in the form of heat from the core to the surface. The adjective geothermal originates from the Greek roots γη (ge), meaning earth, and θερμος (thermos), meaning hot. At the core of the Earth, thermal energy is created by radioactive decay and temperatures may reach over 5000 degrees Celsius (9,000 degrees Fahrenheit). Heat conducts from the core to surrounding cooler rock. The high temperature and pressure cause some rock to melt, creating magma convection upward since it is lighter than the solid rock. The magma heats rock and water in the crust, sometimes up to 370 degrees Celsius (700 degrees Fahrenheit).

Geothermal energy is thermal energy generated and stored in the Earth.

Air energy 

Air is basically a mixture of many components in an appropriate ratio that helps humans to be alive by process of breathing. Nitrogen contributes to 78% of it while the Oxygen part is 21%. Finally, that makes a sum of 99%. But what does the remaining 1% percent have? A bag of mixture of Argon, Methane, Krypton, Carbon DiOxide, Neon and Helium makes the air complete by fulfilling the 100% criteria.

Wave energy

Wave energy is nothing but the the energy that is produced with the help of the waves that occurs . The speed of the waves and the energy produced is directly proportional. When the speed of waves increase, the energy produced would be more and when the speed of the wave is less, the energy produced would be very less. This is typically because the energy of wave is calculated with the help of the height of the waves also. When there is more speed the waves would rise up, with more energy and thus producing great energy.

Sound energy 

Sound energy basically is the form of energy, which is generated when sound waves in the form of vibrations travel through any particular medium like air or water. Sound energy can also be considered as one form or a subset of mechanical energy. Sound energy is produced when any object vibrates and the vibrations are passed on to the nearby air particles. One might not have the touch and feel of sound energy but it is present. The sound energy usually travels the least distance among all forms of energy. Sound energy is measured in terms of decibels.

Hydro Energy 

Hydro Energy is created by the force of falling water. Hydro Energy is a renewable energy source. Electricity created using hydropower is known as hydroelectricity. Hydro energy is the energy available in either running or falling water or both, which may be harnessed for useful purposes such as irrigation, power houses, saw mills etc. Since ancient times, hydro energy has been used to irrigate the farms and to power mills to grind grains. The modern way to harness the hydro energy is by using turbines that have been crafted using modern technology and machines. The insdustrial revolution is to be thanked for the growth of the modern turbines that can harness more energy from the hydro energy source with very high efficiency.

Who discovered energy?

Different people discovered different types of energy. One source of energy type is heat and it was a man by the name of James Prescott Joule 1818-1889 that discovered that heat was actually a source of energy.

The term 'kinetic energy' was first used by William Thomson who was a British mathematical physicist.

William John Macquorn Rankine discovered potential energy.

Chemical energy was founded by J.Willard Gibbs.

Nicola Tesla discovered radiant energy in 1893.

Enrico Fermi invented nuclear energy.

Laws for energy:

The three laws of thermodynamics:

The first law is called conservation of energy states that that the total amount of energy in the universe in constant. This means that all of the energy has to end up somewhere, either in the original form or a different form. We can use this to determine the amount of energy in a system, the amount lost as waste heat, and the efficiency of the system.

The second law states that the disorder in the universe always increases. For example after cleaning your room, it always has the tendency of getting messy again and this is a result of the second law. As the disorder in the universe increases, the energy is transformed into less usable forms therefore the efficiency of every process will always be less than 100%.

The third law of thermodynamics tells us that all molecular movement stops at a temperature we call absolute zero, or 0 Kelvin (-273oC). Since temperature is a measure of molecular movement, there can be no temperature lower than absolute zero. At this temperature, a perfect crystal has no disorder. When put together, these laws state that a concentrated energy supply must be used to accomplish useful work.

Sources of energy:-

Renewable energy resources include:

Wind energy

Water energy, such as wave machines, tidal barrages and hydroelectric power
Geothermal energy

Solar energy

Biomass energy, for example energy released from wood

There is a limited supply of non-renewable energy resources, which will eventually
run out. They include:

Fossil fuels, such as coal, oil and natural gas

Nuclear fuels, such as uranium

How is energy stored

One way to store it is in the form of chemical energy in a battery. When connected in a circuit, energy stored in the battery is released to produce electricity. Energy can also be stored in many other ways.

Batteries, gasoline, natural gas, food, water towers, a wound up alarm clock, a Thermos flask with hot water and even pooh are all stores of energy. They can be transferred into other kinds of energy.
