Electric stations: advantages and disadvantages

Electric stations are the most important partlife of each person, as they transform the energy of natural resources into electricity. One station is a whole complex of measures, artificial and natural subsystems that serve to transform and distribute all types of energy sources. The whole process can be divided into several stages:

  1. The process of extraction and processing of the primary energy source.
  2. Delivery to the power station.
  3. The process of converting primary energy into secondary energy.
  4. Distribution of secondary (electrical or thermal) energy between consumers.

Electric power industry includes productionenergy at the station and its subsequent delivery through power lines. The most important elements of this chain, such as power plants, differ in the type of primary sources that are available in the region.

Let us consider some types of transformative processes in more detail, as well as the merits and demerits of each of them.

Advantages and disadvantages
Thermal power plants (TPP) aregroup of traditional energy and occupy a significant share of generation of electricity on a world scale (about 40%). Advantages and disadvantages of TPP are given in the following table:

Advantagesdisadvantages

Low cost of consumed fuel

High degree of environmental pollution

Relatively small capex

Significant operating costs for plants

Free accommodation. Do not have a binding to any particular area

Low cost of energy

Small area of ​​accommodation

Advantages and disadvantages of AES

Hydropower plants (HPPs) use water resources as a primary energy source, for example, reservoirs and rivers. Advantages and disadvantages of HPPs are also summarized in the table.

Advantagesdisadvantages

No extraction and transportation of the resource is required

Alienation of fertile lands. Dampness

Ecological compatibility

Violation of aquatic ecosystems

Regulation of water flow

Large accommodation areas

High reliability

Easy maintenance

Low cost

Possible additional use of natural resources

Nuclear power plants (NPPs) - a set of plantsand activities designed to convert the energy that is released as a result of the fission of atomic nuclei, into thermal, and then into electrical energy. The most important element of this system is a nuclear reactor, as well as a set of associated devices. The table below shows the advantages and disadvantages of nuclear power plants.

Advantagesdisadvantages

Low amount of harmful emissions

Irradiation hazard

Low fuel consumption

There is no possibility to regulate the output power

High output power

Low probability of an accident, but very severe consequences of the world scale
Low cost of energy

Significant capital investments

Advantages and disadvantages of motor transport

Transportation is an equally important stagefuel resources to the power plant. This process can be carried out in several ways, each of which has its own merits and demerits. Consider the main methods of transportation:

  • Water transport. Delivery is carried out with the help of tankers and bunkering.
  • Automobile transport. Transportation is carried out in tanks. The ability to transport only liquid or gaseous fuels determines the existing advantages and disadvantages of road transport.
  • Railway transport. Delivery in cisterns and open wagons for long distances.
  • Suspended cable cars and belt conveyors are rarely used and only for very short distances.
