Electricity....Lets save It !!!!

  1. 1. Discovery of electricity • About six hundred years back the people of Asia Minor and Greece had a very crude idea of electricity. • Next, the American Scientist Benjamin Franklin proved with the help of a kite that there is electric power in the clouds. • The lightening is nothing but the discharge of electricity that the clouds contain.

  2. 2. Using power transformers to transmit power at high voltage and with low loss. Electricity has been generated at central stations since 1881. Central power stations became economically practical with the development of alternating current power transmission.
  3. 3. Electricity generation is the process of generating electric power from sources of electricity. The fundamental principles of electricity generation were discovered during the 1820s and early 1830s by the British scientist Michael faraday. His basic method is still used today: electricity is generated by the movement of a loop of wire, or disc of copper between the poles of a magnet. The other processes, electricity transmits distribution, and electrical power storage and recovery using methods are normally carried out by the electric power industry.
  4. 4. Thermal Power This is made by coal. Hydro Electric Made by speed of water. Nuclear Power Made by fusion. Fossil Fuel Made by fossils of dead animals. Solar Energy Made by solar energy of sun. Wind Power Made by speed of wind.
  5. 5. Fossil fuel is a material that can be burned and that comes from the fossil remains of animals and plants, such as long-dead dinosaurs. Some examples of fossil fuels are coal, natural gas and petroleum. This source is currently available and it is not dependent upon the weather. Some of the problems of fossil fuel use are that it causes pollution, it is a non- renewable resource and it needs to be mined from the earth.
  6. 6. It is produced by the wind turning a turbine. Using windmills, has been known for many centuries. Also, in order to be effective, the wind speed at a power site has to be over 12 kilometers per hour. Finally, this source of power is costly and requires special equipment. This source of energy produces almost no pollution, and it is easy to capture in many parts of the United States.
  7. 7. Solar energy is the energy that comes from the sun. We capture solar energy through solar panels. This energy produces no pollution; also it doesn’t taint anything. About the equivalent of 22 million barrels of oil of solar energy hits the United States alone per day. This might sound like the perfect energy but it is costly and besides, you can’t be sure that the sun will shine brightly without cloud cover everywhere in the country every day.
  8. 8. It is produced when water falls from a high place to a low place. The turbine drives the generator. This form of energy produces little pollution; in addition, it does not ruin the water. The water still can be used for other purposes. Hydroelectric power does not cost any more than fossil fuels. Another advantage is that there are a lot of lakes or rivers where a dam can be built to produce energy. One disadvantage is that fish, such as salmon, can not climb over the dam, so the dam changes the environment.
  9. 9. It is made by fusion .It is produced in the reactor of a nuclear power station. The energy turns water into steam, which drives a turbine that powers a generator. This energy, unlike other sources, produces lots of radioactive waste. It produces lots of energy and can be made to power major cities. 00 : 01
  10. 10. In a conventional thermal power station, a fuel is used to heat water, which gives off steam at high pressure. This in turn drives turbines to create electricity. At the heart of a power stations is a generator, a rotating machine that converts mechanical energy into electrical energy by creating relative motion between a magnetic field and a conductor. The energy source harnessed to turn the generator varies widely.
  11. 11. During the day when it is brighter outside, open the curtains and use the sunlight instead of turning on the lights. Don't windows or doors open when the air conditioning is on. This makes the AC have to work harder to cool a room.
  12. 12. Turn off the lights when not in use Take advantage of daylight by using light-colored, loose- weave curtains on your windows to allow daylight to penetrate the room. Also, decorate with lighter colors that reflect daylight. De-dust lighting fixtures to maintain illumination. Use electronic chokes in place of conventional copper chokes.
