How Electricity is Produced
Electrical energy was one of man’s greatest discoveries. It has helped build new civilizations. The large amount of electricity produced has its source in fossil fuels, nuclear fission, water, and wind. This article will explore the different methods of electricity production.
Electricity is churned out by enormous turbines. These turbines need a support to be moved. There are various ways of moving these turbines:
By burning fossil fuels: Electricity is produced when the blades of a turbine are moved by enormous amounts of vapour. This vapour is generated by heating a lot of water in huge furnaces. The water is heated by burning fossil fuels like coal, petroleum, and natural gas. This method releases enormous amounts of carbon dioxide in the air, thus severely polluting our atmosphere. It is important to turn to alternate methods of electricity production for long-term benefits.
By water: You must have heard how dams are constructed to produce electricity. A popular method to produce electricity, a water dams serves two purposes: restricting water bodies and producing electricity. Water dams use the river water to move turbines, helping them produce electricity. Electricity generated this way helps control air pollution; however, this method of electricity production adversely affects the ecosystem in the water bodies.
Water accounts for 90 percent of the world’s electricity generated through renewable resources.
By wind: Electricity is produced when wind energy is converted to electrical energy. Wind mills or wind turbines are used to churn up enormous amounts of wind energy which is then converted into electrical energy.
The latest in wind energy advancement tells us that wind energy is helping create portable cell phone chargers.
By nuclear fission: Yes, nuclear fission does not only make atom bombs, but also helps produce electricity. Nuclear fission causes a chain reaction where the element Uranium is bombarded by neutrons causing it to split. Every time a Uranium nucleus is split, more neutrons are released, causing more splits in the already split Uranium nuclei. The resultant chain reaction generates a lot of heat which is used to heat water the vapour of which eventually moves turbines to create electricity.
By bio-waste: With technological advancements, electricity is also being produced by bio-waste. Bio-gas is a typical way of generating electricity 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 electricity.

Why is the electricity produced when we could move the turbine around?
No complex words please, please answer what i want to know? Why is the electricity produced? Thanks really much, you guys have helped me a lot
Its down to the fact that if you move a conductor in a magnetic field you induce a flow of electrons.
If you take the turbine shaft and put a series of magnets on it, you can then put this shaft inside a series of copper coils, as you turn the shaft the coils will produce a voltage.
As the magnets turn though you get voltage one way then the other (AC – Alternating Current) – this is fine for mains power though.
The number of coils, the spacing and the size of the magnets all affect the overall voltage and also the speed of the turbine.
You can demonstrate the effect if you have a galvanometer (a very sensitive volt meter) – connect it to each end of a copper wire about 6 or 9 inches long, pass the wire between the North and South poles of a magnet and watch the meter show a response.

If you move magnets it makes electricity.
