Many people are finding the information about electrical energy definition to know about it clearly.The energy that is formed by the movement of electrons from one place to the other is called the electrical energy. Since electrical energy cause the movement of electrons or electric charges, it is the form of kinetic energy.
The amount of electric energy depends up on the speed of the electric charges; the more of electric energy is carried when the movement of electrons or electric charges is faster. Car Battery is an example of electric energy in action, where the chemical reaction produces the electric current which is supplied to the circuits in the car. The basic unit of electric energy is called joule and you can learn electrical energy definition through online.

What are the uses of electrical energy?
The notable uses of electric energy or electricity in our day to day lives are:
- Residential purposes: In this modern era nothing is possible without the electricity supply; electricity has become very essential one for the household purposes. It is mainly used for television, water heaters, refrigerators, air coolers, lighting, computing among other purposes.
- Transportation: Electricity is widely used for the transport system across the world. Major countries use electricity as a fuel for the trains in the railway network and it is also served as a fuel for the electric vehicles, which promotes the greener transportation.
- Industrial purposes: Industries require huge amount of electricity for running machines for manufacturing process.
- City power: Even the city requires the electricity for street lights, stop signals, some signs, etc.
- Health care purposes: The powerful lighting is needed for the doctors during the operations on the patients, and if there is no electricity, even the surgeries are impossible with the modern equipment.
What are the primary sources of electricity?
- Sun: The sun is the basic source of energy and its energy is called the solar energy. The solar energy can be used for the production of electricity with help of photovoltaic cell which directly converts the sun light into electrical energy.
- Wind: The kinetic energy of the wind can be utilized to create electricity with the help of efficient wind mills which convert wind energy to electricity. However, the wind energy can be produced only in the windy areas.
- Water heads: The kinetic energy of flowing water can spin turbines and produce electricity. The power plants that are used to produce electricity from water heads are called as the hydroelectric power plants.
- Fossil fuels: Fossil fuels are the great source of electricity which would include natural gas, oil, and coal. Whatever be the fuel in gaseous, liquid or solid state, the principle is the same for all the kinds. The combustion of the fuel is used to produce steam from boiling of water, which is again allowed to expand via nozzles of the turbine and then electricity is produced with the help of turbine system.
- Nuclear energy: Another source that produce huge amount of electric energy is the nuclear energy. The nuclear fission process releases large amount of energy and is used for producing steam which rotates the turbine, producing electricity.
