Electricity is the power that drives the planet. We can not think about our lives without power. From televisions and refrigerators to vehicles and computers, every thing runs on power. Nearly all of it is 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 as the various resources of electricity.

How to Generate Electricity

Electricity is generated in numerous kinds of power plants. The basic mechanism involves use of the different sourced elements of electricity to rotate the blades of a turbine. Since the blades rotate, electricity is manufactured in the generator. This principle was initially found by British scientist Michael Faraday. As per 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 propane. Fossil fuels were formed an incredible number of years back when dead plants and animal remains got buried under layers of soil and under great pressure and temperature, got became their present form. Fossil fuels would be the main electrical source in the us. Very nearly 49. 8% of electricity in the us is generated by burning coal. For long these have been the absolute most widely used supply of electricity on earth. However, as a result of heavy dependence of the world on fossil fuel for way to obtain electrical power, they've been being depleted at a much faster rate than they could be formed. This really is putting stress on the remaining deposits of fossil fuel and making the planet look for alternative energy sources. A problem of using fossil fuels to build electricity is that burning them gives out plenty of toxic gases that pollute the environment and donate to world wide 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 wide range of energy. The fissile material mostly used are Uranium - 235 and Plutonium - 239. Because of its immense potential, lot of research will be done on nuclear energy such that it becomes one of many major electricity sources. However, one significant problem of using nuclear energy being an electrical power source is managing nuclear waste. These 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 plants in the oceans where they're dumped mostly raises a huge question of the efficiency of these measures. Also, even though the fission reactions are very well controlled in nuclear power plants, in case the checks fail, it could cause a nuclear disaster.
