Power Generation: Coal, Solar, Wind & Nuclear
Transcript of Power Generation: Coal, Solar, Wind & Nuclear
Nuclear energy is power produced during a nuclear reaction. Energy released from a highly reactive element in the nuclei of the element is known as nuclear power. Nuclear energy/power can be produced in two different ways; by nuclear fusion and nuclear fission. Nuclear energy can be produced naturally from the sun and the stars or, when the sun releases heat to the atmosphere (it adds to nuclear radiation and energy).
Coal is a fuel that is found in the ground. The energy that coal produces is from the sun and it is stored in plants. When coal is burned, it produces energy as heat. The coal's heat energy can be turned into electrical energy which happens at a power plant. *
how power is generated through solar energy
Advantages & Disadvantages
What is Electricity?
Electricity is the flow of electric charges and is a controllable element as it is controlled by an on/off switch.
In a circuit, electricity is supplied by a power source (battery) and is measured a voltmeter in volts.
Electricity is the creator of many energy charged equipment such as; electromagnet radiation, static electricity and electronics.
What is Generation?
Generation is the process of generating electrical current to another power source.
A generator is an equipment that produces energy by the movement of a conductor in a magnetic field.
Electricity travels through a number of stages before reaching at it's destination (homes, industrial uses, commercial uses etc).
Electricity is first created at the generator then distributed to the transformer, where the electricity travels through to the transmission lines. Then, the electricity travels to the substation. The substation divides the electricity and sends it in different paths over wires called distribution lines. These distribution lines then transfer the electricity to your home.

Firstly, coal is mined from the ground and taken to a generator (power plant). When in the power plant, it is burned in a boiler which makes the water in the boiler pipes becomes into steam. The steam travels through the pipes in the turbine and spins the turbine blades. In the generator, big magnets spin close to the coils of wires which are where electrical currents are produced.
After the generator, the electricity travels to the transformer. Here, the electricity transferred to transmission lines then a substation. The substation divides the electricity the electricity and sends it in different paths over wires called distribution lines. These distribution lines then take the electricity to your home.

Wind is a main feature of weather patterns and is almost always present with or without an existing storm in the area. Wind can be at any power from a simple breeze to a hurricane, and is created in the atmosphere.
There are certain devices/structures that are built in a field where wind occurs frequently. These are called wind turbines, are hoisted atop a tower to get maximum wind and will use the power of the wind to generate electricity. As long as there is wind, the turbines will create electricity.
The advantages of nuclear energy are:
- Nuclear power points do not need a to build it
- Nuclear energy does not contribute to carbon emissions
- Nuclear energy produces a lot of energy from a small amount of fuel
- Nuclear energy is very reliable
- Produces a small amount of waste( though its radioactive waste)
The disadvantages of nuclear energy are:
- Nuclear energy waste is radioactive
- The disposal of nuclear waste is very expensive
- Nuclear accidents and incidents can spread radiation to the environment near the power point
- A nuclear power point meltdown can lead to radioactive particles being polluted into the environment
