Electricity is the power that drives the entire world. We cannot think of our lives without power. From televisions and refrigerators to vehicles and computers, everything runs on power. Nearly all of it's provided in the form of electricity that is generated in numerous kinds of power plants. These power plants use fossil fuels, nuclear power, wind, water or geothermal energy whilst the various sourced elements of electricity.

How exactly to Generate Electricity

Electricity is generated in numerous forms of power plants. The fundamental mechanism involves usage of the various resources of electricity to rotate the blades of a turbine. Because the blades rotate, electricity is manufactured in the generator. This principle was initially found by British scientist Michael Faraday. According to the principle when an electric conductor (say copper wire) is rotated between the poles of a magnet, electricity is generated.

Resources of Electricity

Fossil Fuel: Fossil fuels include coal, oil and gas. Fossil fuels were formed millions of years back when dead plants and animal remains got buried under layers of soil and under some pressure and temperature, got converted into their present form. Fossil fuels are the main electric source in the usa. Almost 49. 8% of electricity in the us is generated by burning coal. For long these have been probably the most popular way to obtain electrical power in the world. Nevertheless, because of heavy dependence of the world on fossil fuel for supply of electrical power, they are being depleted at a faster rate than they could be formed. This is putting strain on the remaining deposits of fossil fuel and making the entire world try to find alternative energy sources. A major problem of using fossil fuels to build electricity is that burning them gives out lots of toxic gases that pollute the environment and contribute to worldwide warming.

Nuclear Energy: Nuclear energy is obtained through nuclear fission. This method involves the splitting of nuclei of certain elements which results in the release of a large amount of energy. The fissile material most often used are Uranium - 235 and Plutonium - 239. Due to its immense potential, lot of research is being done on nuclear energy so that it becomes one of the major electricity sources. However, one significant problem of using nuclear energy being an electric power source is managing nuclear waste. They are radioactive products whose radiations can have harmful effects on the living things. Even though utmost care has been taken so that they are safely disposed, effects of nuclear radiations on the plant life in the oceans where they have been dumped mostly raises a huge question of the efficiency of those measures. Also, even though the fission reactions are extremely well controlled in nuclear power plants, in case the checks fail, it can cause a nuclear disaster.
