Energy in general is the most important common denominator that humankind owns.
Along with the advanced development of humankind in the twentieth century especially, energy has become the most important exponent given its ascension. It is generally accepted that human evolution is directly proportional to the increase in energy consumption.
If at the basis the natural resources were exploited for energy production, in time it was discovered that these natural resources are not infinite. This reality is more worrying as primary resources for creating electricity have become increasingly scarce and very expensive.
While coal still remains an exploitable resource, oil and gas reserves are endangered in the long term. However, electricity has become increasingly used in households and larger areas in the industrial sector.
Electricity is a specific form of energy representing the empowerment of electric charges in the presence of an electromagnetic field. As a form easy to exploit, electricity has always known a transitional period. Today, electricity enjoys consistent transition at both the production and at the increasing global use. This transition aims to fulfill all current and future global targets.
Among the main forms of electricity generation we mention the most important:
Alternative energy sources
All types of electricity acquire private processes of production, but transmission, distribution and consumption know the same ways of use, forming electrical systems that encompass virtually all the energy produced that it manages up to final consumption.
The technological process by which electricity is described involves 4 major steps:
All processes have as main tools the centralization of energy and transport from one stage to another, the chain is shut whenit reaches the final use.
From the moment the energy is stored in power plants, usually by quantify and transmitting in transmission systems.
At their basis power plants were designed as being of high power, capable of supplying with electricity large consumptions.
In time, especially nowadays and in the future the foundation ideology of these power plants was based on building them according to their primary resources for energy production. Increasing importance is given to lower power plants.
Subsequently power plants follow the energy transport process through air electricity networks towards distribution areas, embedded, power grids make up a system, usually represented by the electrical systems at a national level. The trend is to expand the national systems’ network towrads the global ones according to the needs and geographical areas around the world.
Once arrived at the distribution channel the energy is directed in electricity substations usually of lower power than those in the production area, and will be transported to the users. Transportation to users is done via two types of networks: by air and underground.
All these aspects also take into account the technical factors involved, and the economic factors in the area.
Reaching the last part,the final usage of the electricity, from the distribution network there are power plants of connection to final consumers. Technical and economic solutions are adapted according to the types of consumers, large or small.
