Sources of electricity and types of electric power plants

Sources of electricity


Sources of electricity: The energy problem is one of the major problems of mankind. The prime sources of energy, at the moment, are gas, coal, and oil. According to the forecast data, oil reserves will last for 40 years, coal for 395 years and gas for 60 years. The global energy system is undergoing tremendous challenges.


Regarding electricity, we represent the sources of electric energy by various power plants - thermal, hydroelectric, and nuclear power plants. Because of the rapid depletion of natural energy sources, mankind finding alternative methods for generating energy.


You must read about the invention of electricity and inventors that invent electricity.


The sources of electricity can be electrical products or devices that convert various types of energy into electrical energy.



Basic Sources of  electricity



Thermal power plants



Thermal power plants work on fossil fuels like fuel oil, coal, peat, gas. We build up thermal power plants near large oil refineries, mainly in the region where natural resources are present.



Hydroelectric power stations



We build them in places where we block large rivers by a dam, and thanks to the energy of the falling water, the turbines of the electric generator rotate. We consider the production of electricity by this method the most environmentally friendly because there is no burning of various types of fuel, therefore, there is no harmful waste.



Nuclear power plants



When we want to heat the water we require heat energy, which is released because of a nuclear reaction. Because it is like a thermal power plant. Nuclear power plants are enormous sources of electricity.



Unconventional energy sources



Unconventional energy sources consist of sun, wind, ocean tides, and the heat of turbines. Scientists say that by 2050, unconventional energy sources will become the major ones, while conventional ones will lose their significance.



Energy of sun



There are several ways to apply it. During the physical method of obtaining solar energy, we use galvanic batteries that can absorb and convert solar energy into electrical or thermal energy. We also use a mirror system, which reflects the sun's rays and directs them into tubes filled with oil, where it concentrates the solar heat.



The major advantages of solar energy are the general availability and inexhaustibility of sources, complete safety for the environment, and the main environmentally friendly sources of energy.



The major drawback is the need for extensive areas of land for the construction of a solar power station.



Wind energy



Wind farms can produce electrical energy only when forceful winds blow. The windmill is the main modern energy source of wind energy. We program two operating modes in it - weak and strong winds, and there is also an engine stop if there is powerful wind.


So, wind energy power stations are enormous sources of electricity


The major disadvantage of wind power plants (wind farms) is the noise received during the rotation of the propeller blades.



Tidal power plants



Tidal energy is used to produce electrical energy. To build the simplest tidal power station, you need a pool, blocked by a dam, a river mouth, or a bay. We equip the dam with hydraulic turbines and culverts.


Water at high tide flows into the pool, and when we compare the water and pool levels, the culverts are closed. With the approach of low tide, the water level decreases, the pressure becomes of sufficient strength, turbines and electric generators begin their work, gradually the water leaves the pool.


Fresh sources of energy in the form of tidal power plants have some disadvantages. 



  • violating the normal exchange of fresh and saltwater.
  • Impact on the climate, because of their work, the energy potential of the water, the speed, and area of ​​movement change.



Advantages



  • It is environmentally friendly.
  • It produces low-cost energy.
  • Tidal power plant reduces the burning and transportation of fossil fuels.




New promising energy sources - biomass



Biomass is primary and secondary. To get energy, you can use dried algae, agricultural waste, and wood, etc.


To date, a decent amount of garbage has accumulated in the world that degrades the environment, garbage has a detrimental effect on people, animals, and all living things. That is why we require the development of energy, where secondary biomass will prevent environmental pollution.


Advantages - the concentration of carbon dioxide does not increase, we solve the problem of using garbage, therefore; the environment improves.
