The salaries are different and the working hours are different.
1. The salaries are different. Wages in thermal power generation are generally 6,500 yuan/month, while wages in wind power generation are generally 7,000 yuan/month.
2. Working hours are different. Working hours in thermal power generation are typically five days off and two days off, while working hours in wind power generation are typically six days off and one day off.
Which of wind, nuclear, hydroelectric and thermal energy is completely clean?
Wind energy and photovoltaic energy are new sources of energy that China strives to develop. The electricity network must fully absorb them and use them as a priority. Hydroelectricity also requires priority use ofelectricity network during flood periods. This is a comprehensive consideration of a series of factors such as environmental protection and the reduction of carbon emissions by the State. The electricity network can therefore do nothing! Why is it called “junk electricity”? There are mainly two aspects.
First, photovoltaic and wind power have low installed capacity and are dispersed, making it difficult to meet the peak load regulation needs of the power grid! To put it simply, when the weather is sunny and the wind is blowing, the insufficient thermal power will be supplemented. When short-term electricity demand increases rapidly, photovoltaic and wind power cannot meet it. On cloudy days and when there is no wind, the power plant is dead. In the event of a power outage, thermal energy is used! And the price of new electricity sur the network is relatively high! This means that when the sun rises, the heat load is reduced and when the sun sets, the heat load increases. For the power grid, constant adjustments are required, which is not conducive to the safety and economical operation of the power grid. Secondly, wind and photovoltaic power are not stable enough, resulting in the transmission of harmonics to the power grid system, which will increase power losses and affect motor efficiency, which will affect the manufacturing of high precision ! These two reasons should be the reason why photovoltaic and wind energy are called "garbage energy".
Both are new energy production, which are currently encouraged and vigorously developed by the state, and there are huge state subsidies. , the network settlement price for thermal energy isabout 0.3 yuan per kilowatt hour, and the price of wind and photovoltaic power generation ranges from 0.3 to 0.8 yuan.
Both types of electricity generation had a fatal flaw at the time, namely their intermittency. Solar power produced electricity during the day and could not produce electricity at night. Wind power could produce electricity when it was windy. but could not produce electricity when there was no wind. These two types of power generation are actually not well received by the power grid, but due to state support for new energy and requirements for energy saving and emission reduction, the electricity network company must accept them unconditionally.
There are more and more of these two types of electricity production, which lead to instability in the electricity network. Currently, we relys mainly on thermal energy peak shaving, pumped energy storage, wind energy heating and wind energy heating. building energy storage power plants to solve intermittent problems. At the same time, wind and solar energy forecasts are becoming more accurate, which also reduces pressure on electricity grid regulation.
The only thing that is completely clean is wind power.
Strictly speaking, hydropower cannot be considered clean, because it will produce pollution during the construction process and also raise the groundwater level, which can easily cause water problems. ground. Hydropower also has an impact on the climate. The Aswan Hydroelectric Power Plant in Egypt is the largest hydroelectric power plant in the world, but it ultimatelywas bombed due to environmental concerns.
Nuclear energy will produce nuclear waste. Currently, there is no effective way to deal with nuclear waste except storage.
As for thermal energy, it is the most polluting among these types of power plants. When coal is burned, dust, sulfur dioxide and nitrogen oxides are produced. YesMost polluting
