› How its created.
Hydrogen and nuclei must be together. The protons form each will tend to deny each
other because both have the same positive charge. For example trying to place two
magnets together and feel that each of the magnets they both push each other
apart.
› The advantages/disadvantages.
Advantages: nuclear fusion reduces a amount of energy that is generated from
fossil fuels for example: coal and oil.
Disadvantages: Organizations often use this argument in favor of nuclear energy
but it's a partial truth. Much of the consumption of fossil fuels is due to road
transport, used in heat engines.
› Where is it use.
Nuclear power stations operate in 31 countries. China has 28 new
reactors under construction, and there are also a considerable number
of new reactors being built in South Korea, India, and Russia.
› How is it created.
tidal energy is produced through the use of tidal energy generators. Large
underwater turbines are placed in areas with high tidal movements.
Advantages/Disadvantages.
Advantages: Tidal energy is a renewable energy meaning, this cannot
be depleted. Tidal forces got their own origin in the moon and sun’s
gravitational reaction.
Disadvantages: Power plants harnessing tidal energy are linked with
higher upfront cost required for construction. This therefore displays lack costefficiency and effectiveness in the worldwide energy market.
Where is it use.
The tidal power plant at the Rance River estuary in Brittany, France,
uses a barrage. It was built in 1966 and is still functioning
› How is it created.
converts kinetic energy in the wind into mechanical power
Advantages/Disadvantages.
› Advantages: it’s a clean fuel source.
domestic source of energy.
It's sustainable.
› Disadvantages: Noise Disturbances.
Threat to Wildlife.
Wind Can Never Be Predicted.
where is it use.
India, Germany, France, Spain, United Kingdom, China, Denmark, Italy, Portugal.
› How is it created.
is a reflective surface used to collect or project energy such
as light, sound, or radio waves.
Advantages/Disadvantages.
› Advantages: High gain.
High directivity.
› Disadvantages: Requires reflector and drive element
Cost
Size
Where is it use.
› How is it created.
Converts the energy of light directly into electricity by the photovoltaic
effect, which is a physical and chemical phenomenon.
Advantages/Disadvantages.
› Advantages: It is present in abundance.
They have no moving parts and hence require little maintenance
and work quite satisfactorily without any focusing device.
› Disadvantages: The entire process of manufacture is still very expensive as silver
is used for interconnection of these cells in the panel, which is a
very expensive metal.
where is it use.
Germany, Italy, China, USA, Japan, Spain, France, Belgium, Australia, Czech
Republic.
› How is it created.
coal, oil and gas are called ‘fossil fuels’ because they have been formed
from organic remains of prehistoric plants and animals.
Advantages/Disadvantages.
› Advantages: Easily Available.
Produce Large Amount of Energy.
High Calorific Value.
› Disadvantages: Environmental Hazards
Rising Prices
Acid Rain
Where is it use.
Afghanistan, Albania, Algeria, American Samoa, Andorra, Angola.
› How is it created.
A hydraulic turbine converts the energy of flowing water into mechanical
energy. Hydroelectric generator converts this mechanical energy into electricity.
Advantages/Disadvantages.
› Advantages: Once a dam is constructed, electricity can be produced at a
constant rate.
The lake's water can be used for irrigation purposes.
› Disadvantages: Dams are extremely expensive to build and must be built to a
very high standard.
The flooding of large areas of land means that the natural
environment is destroyed.
Where is it use.
China, Canada, Brazil, the United States, and Russia.
