ENERGY
The energy we consume has many different uses.
Household uses.
Industrial uses.
Energy sources
Are natural resources from which we obtain diferemt forms of energy that can be transformed for a specific use.
They are classified in several ways:
By availability in nature and capacity for
regeneration
By origin
By environmental impact
By use in each country
Electricity.
Electricity is the most widely used form of energy in industrialised societies for two reasons:
It can be transported long distances inexpensively
and with very little energy being lost
It can be easily transformed into other forms of
energy, such as light and heat.
Electric power plants.
Electric power plants are facilities where primary or secondary energy s transformed into electrimty, Once electricity is generated, it must be transported to towns, cities or industrial parks.
How an electric plant works
The turbine converts mechanical energy into the rotating movement
of a shaft.
Conventional electric power plants.
Nuclear power plants.
This type of plant includes a nuclear fission reactor that produrces the
pressunsed steam needed to move the turbme rotor.
Combined cycle power plants.
Efectnctty ts generated as a result of two combined cycles, a cycle that uses air and gas, and a conventional thermal cycle During the first cycle, a gas turbine is used that includes a compressor.
Hydroelectric power plants.
This type of power plant uses the potential energy provided by the height of the stored water in a dam, converting it mto kinetic energy. This energy moves the blades of the turbine
