The Electromagnetic waves that carry electromagnetic energy is a family of waves based on the frequency and wavelength (Tom and Heather 34). Arranged in order of increasing frequency then we have Gamma rays, ultraviolet radiation, X-rays, Visible light, Microwaves Infrared, and Radio waves. Gamma rays have the highest frequency hence a high energy while the Radio waves have the lowest frequency and therefore have less energy.
Electromagnetic energy can be stored in electrical devices such as the capacitors and Inductors. For an electric field, the total energy density which is given by energy stored per unit volume can be determined to be . Where the symbols assume their scientific meaning, this relation is useful in the evaluation of the total energy stored in a capacitor. An inductor is a coil of electrical wire with parameters that enable it to store energy in the form of the magnetic field (David, 1989). The magnetic field energy density is given by. This energy density is useful in the determination of energy stored in the Inductor. Both the electric and magnetic fields play important roles in energy transport as described by the pointing vector (Mats and Jonsson 23). It is however important to notice that the energy associated with magnetic and electric fields is equal and therefore the use of one the equation above can be used to represent the other. It is also important to realize that for an electromagnetic wave with particular energy, the electric field is directly proportional to the energy of “the magnetic field with a constant of proportionality equal to the speed of light” (Mats and Jonsson 30)

Demand Managment and Energy Storage
...effectiveness in building new facilities of generation of power. Implementing the strategy of superconductivity in the power generation process involves using a resistance free technology in the process of electricity generation system comprising the source of electricity and ‘power to the motors and switches that eventually use the power’ (Bellarmine, 2000, p. 143). Huge amount of energy could be stored in superconducting magnetic energy storage (SMES). Uses of strategies like wind and solar energy: Policies are aimed to make these technologies more sufficient and competitive for reducing the load of electricity power generation. Implementation of policy of using pumped...

DEMAND MANAGEMENT AND ENERGY STORAGE
...? Energy Storage and Demand Management I. Executive Summary This report discusses renewable energy storage and management in Scotland. It consists offour major sections. The first section presents the impacts of generating renewable energy upon demand management, hypothesized under three scenarios each with different rates of capacity increases. Demand levels are met effectively under the three scenarios. The second section is concerned about the consequences of either increasing or decreasing renewable energy generation within the Scottish transmission line. Increasing renewables generation would not only modify how the grid network...

Electromagnetic induction
...? Electromagnetic Induction Electromagnetic induction is a principle, which predicts the behaviour of the electric currentswhenever they interact with the magnetic field in the production of the electromotive force. It is a basic principle of operation for many types of electric devices such as motors. In order to understand the characteristics of induction, an experiment set out to investigate the operation of electromagnetic induction. The prime aim of this experiment was to investigate the magnets and coils behaviour, to test Lenz’s law and Faraday’s law, and to test the transformers behaviour. Introduction Electromagnetic induction involves the electric current...

...? Electromagnetism spectrum Electromagnetic radiation (EMR) is one of the key phenomena of electromagnetism, which behaves as photonparticles or propagating waves travelling through space loaded with radiant energy (Abdo 2007). These waves characteristically travels at a speed of light in vacuum and in a straight line (Abdo, 2007). As a wave, EMR can characteristically be absorbed or emitted by charged particles. They also have the magnetic field, as well as electric component that oscillates perpendicularly and in fixed relationship with each other and perpendicular to the direction of the wave energy propagation. Electromagnetic waves are characterized by wavelength and frequency of their waves. In order of decreasing wavelength... and...

Thermal Energy Storage
...The Fundamental Concepts of Thermal Energy Storage I. Thermal energy is not a product of man’s ingenuity but is rather that of nature. Because it is natural, it is renewable and is safe to the environment and to man as well. However, much of this type of energy has been left untapped as mankind has heavily relied on non-renewable sources of energy. These sources of energy are dwindling and have contributed much to the environmental degradation and to the damaged on the ozone layer. With the introduction of thermal energy storage, advances have been made in the efforts of optimizing the use of thermal...

Some devices are not compatible with the electromagnetic structure and they do not perform because they are installed in current advanced atmosphere and modern technology experts have configured electronic devices with multiple codes and designs. While engineers worked on a large number of devices and their functions in an environment of electromagnetic fields, but still there is great...

...concentration gradient must be kept, water must be transparent and a proper system of flushing and disposing of salt must be installed. The feasibility of solar salt ponds can be understood by the results concluded by a study which stated; “A 100m salt pond with 1m storage layer would provide enough energy to power air-conditioners for 50 homes” (Sukhatme, 2008). However, the primary concern with solar salt pond remains the large expense of salt used to drive the pond. The other device widely used to trap solar energy is the flat plate collector. These collectors are used to trap energy for temperature requirements up to 75°C (Prakash & Garg, 2000). The principle on...

...and a maximum when the current in the secondary (pickup) coil is zero and is changing positively. When the current in the primary coil is zero, the current in the secondary (pickup) coil is positive and a maximum. The reason behind this is that the EMF induced by a magnetic field is proportional to the time derivative of the magnetic flux. References Balanis, C. A. (1989).
