Have you always wondered where electrical energy comes from? It is difficult to imagine our lives without its existence. Almost everything in our day by day lives depends on access to electricity.
Electrical energy was one of human beings biggest discoveries. It has helped build new civilizations. The large sum of electrical energy produced has its source in fossil fuels, nuclear fission, water, and wind. This article will explore the different techniques of electricity production.
Electrical energy is churned out by enormous turbines. These turbines need a support to be moved. There are several ways of moving these turbines:
By water: You must have heard how dams are constructed to produce electrical energy. A popular technique to produce electrical energy, a water dams serves two purposes: restricting water bodies and producing electricity. Water dams use the river water to move turbines, helping them produce electrical energy. Electricity generated this process helps control air pollution; however, this technique of electrical energy production adversely affects the ecosystem in the water bodies.
Water accounts for ninety percent of the world’s electrical energy generated by renewable resources.
By wind: electrical energy is produced when wind energy is converted to electrical energy. Wind mills or wind turbines are used to churn up large amounts of wind energy which is then turned into electrical energy.
By burning fossil fuels: electrical energy is developed when the blades of a turbine are moved by tremendous amounts of vapour. This vapour is generated by heating a lot of water in vast furnaces. The water is heated by burning fossil fuels like coal, petroleum, and natural gas. This process releases large amounts of CO2 in the air, thus seriously polluting our atmosphere. It’s important to turn to alternate techniques of electrical energy production for long-term benefits.
By nuclear fission: Yes, nuclear fission doesn’t only make atom bombs, but also helps produce electrical energy. Nuclear fission causes a chain chemical reaction where the element Uranium is bombarded by neutrons causing it to spilt. All time a Uranium nucleus is split, more neutrons are released, causing more splits in the already split Uranium nuclei. The resultant chain reaction gives a lot of heat which is used to heat water the vapour of which eventually moves turbines to create electrical energy.
By bio-waste: With technological advancements, electrical energy is also being developed by bio-waste. Bio-gas is a typical way of generating electrical energy in rural areas in countries like India. In fact, a new technology evolved in the state of Bihar in India that uses human waste to generate electrical energy.
