Power Generation

Today we can not imagine life without electricity.Almost all devices work on the supply of electricity, and even those who produce it.

There are several types of power plants - thermal power plants, hydroelectric power stations, nuclear power plants, BES, TEC et al., And the sources from which we have learned to receive so we need energy.At the beginning of the development of the main raw material for energy production is coal.Now, a century later, we have learned to produce electricity using other resources.

electricity production in the world

leading countries for the production of electricity in the world is the United States.In second place China.Then the European Union, Russia, Japan.Nowadays, the production of thermal power mainly occurs with oil, or rather, its faction, referred to as oil.But its use is being phased out.Since we live in a difficult time for the whole world ecologically time comes to replace a "clean" energy production.

One of the first was mastered wind energy.On the ground, everywhere constantly blowing wind.So, the conditions for the development of wind power more than favorable.This eco-friendly and easily accessible production.

Another alternative is the production of electricity using the sun.Interest in the subject has grown considerably in recent years and continues to grow.Many minds are working hard to obtain electricity through solar panels become more profitable.Of course, in various countries, electricity production is developed differently.And if geliostantsii processing of solar energy in Russia are only suitable for some southern regions, for example South America can use this production at full capacity.The same applies to the use of wind energy.In some countries, while in its infancy are geothermal power plants, which use the energy released from the earth in volcanic areas.The services are quite economical power, but the construction of such facilities road.

Electricity transmission

One of the major problems is the energy production and transmission of electricity to the consumer.And consumers are everywhere.Since electricity is generated only in certain places, there is a need to transmit it over long distances.For the transmission of electricity transmission lines are mostly used - overhead power lines.It is known that the transmission of electricity over long distances marked its losses occur.At a considerable distance to the customer transfer can be generally unprofitable.In order to save transmission power, it is necessary to increase the voltage in the power line.The greater the distance, the higher the voltage.It is for this increase in power set voltage transformers.

There is also a "closed" power transmission.It is a closed structure, filled with an electrically insulating gas.Inside are placed under the high voltage wires.

But not always beneficial even such a transfer of power.In some cases, namely at very large distances, it is more expedient to transport fuel for the production of railway: coal - in the capacious cars, and oil - in tanks.

If we talk about the future, because oil is not stable enough for the prices, and inventories become a fraction, soon we will again return to the predominant use of coal for electricity generation.
