Why do power plants burn coal? Can't clean energy be used? Can it replace thermal power generation?

Of course. This is mainly due to the following reasons: the development of new energy is restricted by weak links, the energy consumption density is high, the input cost and technical difficulty are high, and the productivity is low. Thermal energy production is still not the main body of the country, the birth of new industries and the withdrawal of old industries are not synchronized, and power generation and development depend on the development of thermal power plants in many cases, which are very important to industry.

The quality of electricity generated by new energy sources is poor. If it is not converted or directly connected to the power grid in other ways, it may have a great impact on it, bring great risks to it, and finally limit its regulation ability.

At present, most power plants in the world rely on burning oil and coal to generate electricity. Indeed, electric locomotives will not cause pollution to the environment during operation, but the power source of electric locomotives will still cause pollution, so this is a relative concept. Therefore, the positive significance of electric locomotives to the environment will only increase if most power generation depends on clean energy.

For China, coal also accounts for most of China's energy consumption structure. In fact, some studies show that the main mode of power generation in China is coal burning, which is of great significance to the environmental pollution caused by electric locomotives. [Thermal power plant] includes coal burning, straw burning and garbage burning to generate electricity. No matter what kind of fuel, it must be mainly incineration; At the same time, it seems that all kinds of emissions from combustion are not clean energy.

Similarly, more than 60% of electricity demand is due to the gradual decline in the proportion of electricity; However, in the short term, if the growth of new production methods is limited by the cost of standby energy, the power generation cannot be reduced rapidly. But from the perspective of traditional power generation, this seems to be a bigger problem, which is still lower than the emission of automobiles. Fuel is used because emissions are strictly controlled.

New energy has its own disadvantages, such as high energy density, high input cost, great technical difficulty and low production capacity, which restrict the development of new energy. .
