Example of Electric Energy

The most famous example of electric energy that can be found in nature is LIGHTNING. Other examples include

  • Light bulbs
  • TV
  • Radio
  • Computer
  • Toaster
  • Fridge etc

Outside of homes, electricity is also used in hospitals machines such as a x-ray machine and life support machine.

  • Light energy can be converted into chemical energy when the plants absorb the light energy, they convert it into chemical energy for their own nutrition in a process called photosynthesis.
  • Another real life example is the sun, the sun gives plants light energy which afterward is converted into chemical energy.
  • Light energy can also be converted into thermal energy when for example the sun heats up your black shirt or a brick wall outside.
  • There are many example we see in our routine life carrying light energy like lightened candle, flash light, fire, Electric bulb, kerosene lamp, stars and other luminous bodies etc. Each act as a source of light.
  • Even a burning candle is an example for light energy.
  • In a car battery, the chemical reaction causes electrons to gain energy and move in an electric current. A huge cluster of electrons moving through the circuit provides electrical energy in a car. When a lamp is plugged into a wall socket,it turns the lamp on because electric current moves from the wall outlet into the light bulb through its conductor wires which allow the electrons to flow with ease. When the electric charges slow down in the filament to light the light bulb, electrical energy is converted into light energy.
  • Batteries in a cell phone provide stored chemical energy with electric charges. The charges travel through the phone supplying the phone with electricity.
  • Our bodies break down food to produce ATP ( A form of energy ) produced from respiration. It converts the ATP into electrical energy which moves through our nervous system and make muscles contract.
  • A stove plugged into a wall outlet takes the moving electric charges, and the electrical energy flowing through the wire is converted to thermal energy when it reaches the coils and the coils get very hot so it can be used to cook food.

True facts about electric energy

  • Energy cannot be created or destroyed but it can be converted from one form to another.
  • Electricity travels at the speed of light - more than 186,000 miles per second!
  • A spark of static electricity can measure up to three thousand (3,000) volts.
  • A bolt of lightning can measure up to three million (3,000,000) volts, and it lasts less than one second!
  • Electricity always tries to find the easiest path to the ground.
  • Electricity can be made from wind, water, the sun and even animal poop.
  • A 600 megawatt natural gas plant can power 220,000 homes.
  • The first power plant - owned by Thomas Edison - opened in New York City in 1882.
  • Thomas Edison invented more than 2,000 new products, including almost everything needed for us to use electricity in our homes: switches, fuses, sockets and meters.
  • Only 10% of the energy in a light bulb is used as light , 90% is often lost as heat .
  • Enough sunlight reaches earth’s surface each minute to satisfy the world’s energy demand for a year.
