Atomic, thermal power, hydroelectric power and oil power generation, which is the most cost effectiv

Hello, for your question, I would like to answer as follows.

1.The maintenance cost of nuclear power generation is relatively high, because the process is more complex than others, requires real-time monitoring of nuclear radiation, requires high-tech equipment to control the reaction process, and requires very professional personnel to operate and monitor, all of which require cost of equipment and manpower.

2.Atomic energy is the most environmentally friendly. Because this is clean energy, of course, in normal use and without accidents. If you take into account the risk of accidents, then hydropower is in second place.

3.Thermal power generation is the most environmentally damaging because it uses coal and burns heavily to pollute the atmosphere.

It depends on how you generate electricity, and the easiest and most economical way is hydropower, you make your own water wheel, and then install a motor to become the cheapest generator.

However, when it comes to atomic energy, oil is not a renewable energy source, the cost of raw materials will be high after a few years, the efficiency of firepower is low, the pollution is large, the coal burned is not renewable, and it will definitely be very expensive in a few decades, and water power is a natural resource that will never be exhausted.

Although nuclear energy is complex to maintain, the cost per kilowatt-hour of electricity generated is actually lower than that of hydropower, thermal power and oil.

Hydropower is the most damaging to the environment.

Oil and thermal power have an impact on the environment and are smaller than hydropower.

Under normal circumstances, nuclear power has little impact on the environment.

Hydropower is the most cost-saving, and the cost is falling from the sky!

Atomic power generation has the highest maintenance cost, and special attention must be paid to strengthening the safety precautions of reactors and the protection of personnel!

Atomic energy is the most environmentally friendly in a safe state.

Thermal power generation is the most environmentally damaging!

Atomic energy is the most cost-effective.

Thermal power generation.

Advantages: low cost, mature technology.

Disadvantages: pollute the environment, consume primary energy.

Nuclear power generation. Advantages: does not consume primary energy, disadvantages: nuclear leakage will cause nuclear radiation, the cost is higher than thermal power.

Hydropower. Advantages: green environmental protection, saving primary energy.

Disadvantages: The water source cannot be guaranteed, and the cost is higher than that of thermal power.

The cost of solar energy is now the highest, but solar energy is inexhaustible.

The cost can be measured in terms of feed-in tariffs. At present, the feed-in tariff for thermal and hydropower generation is the lowest. Now, the consumption of conventional fossil fuels and the damage to the environment are not included in the cost.

Wind power generation is relatively low in renewable energy, about yuan; The safety of nuclear power generation is the biggest problem, and the cost of waste disposal is also very high; Biogas power generation is only promoted in rural areas, and most of them are matched with specialized electrical appliances, such as biogas lamps; Solar power generation includes thermal power generation and photovoltaic power generation, and the progress of thermal power generation research is relatively slow. With the policy support of some foreign countries, photovoltaic power generation has developed rapidly in recent years. But its cost is very high, the cost per kilowatt-hour is as high as 4.6 yuan. Some people say that photovoltaic power generation is green electricity, but in fact, photovoltaic cells also consume a lot of energy in the manufacturing process, especially the smelting of industrial silicon, which is said to be similar to steelmaking and ironmaking.

Low construction input costs: the lowest heat (but high operating costs, non-renewable coal resources).

Lowest operating cost: nuclear power generation (a large investment, high technology content, but the lowest cost of operation, almost no consumption of resources, the use of neutrons and other reflections to generate energy to generate electricity).

Initial investment: Solar energy should be the largest, followed by nuclear power, and then hydropower.

Operating costs: It should be wind power, followed by firepower. Conventional energy accounts for a considerable proportion of China's electricity market.

Therefore, the operating costs of other new energy sources cannot be counted. For details, you can visit the new energy network.

Nuclear fusion and nuclear fission both generate atoms, but not in the scope of chemical reactions.

It should be the lowest cost of solar energy and wind energy, but not necessarily, for example, the cost of solar energy, the manufacture of controllable ridge silicon to pollute a large area, and the cost of manufacturing solar power plants are not small numbers.

Thermal power 0 4 yuan or socks, hydropower 0 3 yuan, wind energy 0 5, Qiaoqing 0 mu socks 9 yuan, not fast and wide, etc.

Advantages of firepower: relatively low cost of construction, easy availability of conventional fossil fuels, disadvantages of DAO: greenhouse version and harmful gas pollution, high pressure on transportation.

Hydraulic advantages: pollution-free, renewable; Disadvantages: It is greatly affected by seasonal and climatic factors, causing certain damage to the ecological environment.

Advantages of nuclear energy: no greenhouse gases are produced, and the pressure of fuel transportation is small; Disadvantages: radioactivity, difficult to dispose of decommissioning, high construction cost.

FYI.

Nuclear power plants are facilities that use atomic energy to generate electricity, and many countries in the world regard nuclear power generation as an important measure to solve the energy crisis. By the end of 1988, 26 countries and regions in the world had established nuclear power plants, and 414 nuclear power units were connected to the grid for power generation, accounting for 17 of the world's total power generation. A nuclear power plant converts the energy released by the fission of the atomic nucleus into the internal energy of high-temperature steam, and then drives a steam turbine to generate electricity.

The central part of the nuclear power plant is the reactor where the nuclear reaction takes place. The fuel used in the reactor is enriched uranium (including U23524). U235 easily captures neutrons and produces fission, and when fission, 2 or 3 neutrons are released at the same time, and these neutrons go to bombard other uranium nuclei, so that the fission reaction can be carried out continuously, which is called a chain reaction.

During fission, a large amount of primordial energy is released. The chain reaction of the atomic bomb proceeded very quickly, releasing a large amount of rays and energy in a very short time, which was very destructive. Nuclear reactors used in nuclear power plants, on the other hand, require a slow chain reaction to ensure a steady output of energy.

The fuel inside the reactor is made into a cylindrical shape with a diameter of about 1 cm and a height of about 1 5 cm, and then stacked into uranium rods about 3 meters high, packed in thin zirconium alloy round tubes. About 200 uranium rods make up a bundle of fuel rods. A reactor of about 180 fuel rods is piled up.

Uranium rods are inserted in graphite used to slow neutrons. In order to control the number of neutrons and regulate the reaction rate, cadmium control rods, which absorb neutrons strongly, are also inserted into the reactor. Adjusting the depth of the control rod insertion can ensure the normal speed of the nuclear reaction and make the nuclear reactor have a stable output power.

General power stations can be divided into: thermal power stations, hydroelectric power stations and wind power stations. Compared with general power plants, nuclear power plants have many advantages such as no pollution and low cost.

In addition, the fast reactor of nuclear power plants has the following advantages: (1) The fast reactor not only increases the effective utilization rate of uranium resources by dozens of times, but also expands the uranium resources themselves by hundreds of times. This is because, once fast reactors are used in large quantities, uranium ore that is currently considered of little mining value will have mining value.

In this way, the utilization of fast reactors has the potential to provide extremely abundant energy for mankind. (2) The fast reactor nuclear power plant is the best continuation of the thermal neutron reactor nuclear power plant. The development of the nuclear industry has accumulated large quantities of depleted uranium (uranium-238 containing uranium-235 and very little uranium), and it is depleted uranium that is consumed by fast reactors.

Using depleted uranium to generate electricity, while also breeding fuel, is a good thing. When the thermal neutron reactor nuclear power plant develops to a certain level, it is an inevitable development plan to introduce the fast reactor nuclear power plant in time and use the fast reactor to breed nuclear fuel. (3) Fast reactor nuclear power plants have good economic prospects.

Because it has the outstanding advantages of breeder nuclear fuel, the cost of power generation can still be kept low in the case of fuel. It is estimated that the cost of generating electricity from oil power stations will increase by 60% if the oil is **** 100%; Natural uranium **** 100%, light water reactor nuclear power plant power generation cost increased by 5%, while fast reactor power generation cost only increased.

Remember to adopt it.
