Energy and its transformation
Energy sources are natural resources from which we obtain different forms of energy that can be transformed for a specific use.
the operating of electncal appliances, heating systems, hot water systems, heat for cooking and for means of transport for example.
: the operating of factones and companies, construction, agriculture and so on.
The energy we consume has many different uses:
Electricity is the most widely used form of energy in industrialised socieues for two reasons:
It can be easily transformed into other forms of energy, such as light and heat
It can be transported long distances inexpensively and with very little energy being lost.
Electric power plant
Electric power plants are facilities where pnmary or secondary energy is transformed into electriciy. Once electricity is generated, is must be trasported to towns, cities or industrial parks.
How an electric power plant work?
Electncal power plants use an external source of energy to produce electricity to do this, they rely on a
The turbine converts mechanical energy into the rotating movement os a shaft
An alternator has a fixed part, called a stator, and a moving part, called a rotor, connected to the turbine shaft
Non-convetional electric power plants
The environmental problems caused by conventional power plants have led to the creation and development of non-coventional or alternative energy power plants.
The two principal non-conventional electric power plants are:
Wind power plants and wind farms
These power plants use the kinetic energy uf the wind to move the blades of a rotor at the top of a tower, this is referred to as the wind turbine.
Wind farms are a clean form of generating electnmty However, they can only be instaled in places with appropiate wind conditions.
Solar power plants
These plants use the energy from the sun There are two main types of instaflations: photo-thermal and photovoltaic power plants.
