Thermal power plants use coal. As there are large coal reserves on earth, the price of coal is relatively cheap. In addition, the cost of building a thermal power plant is lower than that of a hydroelectric power station of the same power, because a thermal power plant only needs to build furnaces, exhaust installations, production units, coal transportation facilities, etc., and it is safer to build these components, while building a hydropower plant is safer. Before a power station is built, it is necessary to intercept the river and use countless steels and cements to build a reservoir on the river so that water power can be used. to drive the generator. Thermal power production is not affected by climate, while hydropower production is affected by climate. However, coal is not renewable after being burned, and the energy utilization rate is very low. Only less than a third of the energy is used and two thirds of the energy becomes waste heat. the river rose several degrees. The fish and shrimps are dead. Additionally, the exhaust gases emitted from power plants also pollute the environment.
To answer this question, we must answer it from the following three aspects: 1. Not at the moment, because it has its positive effects. 2. It will happen one day. Every tank has a lifespan, and when it reaches the end of its lifespan, it will definitely explode. 3. Perhaps the question you asked is whether we can proactively blow up the dam in advance due to the shortcomings of the Three Gorges Water Conservation Project, as M predicted . Huang Wanli. By analyzing the principles of river movement,the Three Gorges has many similarities with Sanmenxia, except that its sedimentation rate is slower than that of Sanmenxia. According to my personal research (of course, this has not been recognized by experts, including those of Huang Wanli), the elevation of Tongguan of the Yellow River can be reduced to about 324 meters, which can eliminate the damage caused through Sanmenxia to the Guanzhong Plain. Similarly, as long as the Three Gorges uses If the method is correct, we can abandon some special interests, and the problem of siltation at the end of the reservoir can be easily solved. For example, if most of the sediments deposited in the Sanmenxia Reservoir are removed by floods, the amount of sediment passing through the dam each year will be equal to the total amount of sediment in the Yellow River in the previous year, which can guarantee that Tongguan's elevation drops to normal levels (it should beof 323.5 now) m) and returns to the historical average elevation speed. Similarly, the siltation problem at the end of the Three Gorges Reservoir can also be resolved. It's not a big problem at all. Huang Wanli's prediction may be completely broken. However, I don't know if there was any such consideration. the design of the Three Gorges Reservoir, although it was not the case at the time, its reconstruction will now be feasible. As for blaming earthquakes, droughts and other natural disasters on the Three Gorges, I personally think that this has little basis and therefore there is no need to blow up the Three Gorges .
Current methods are somewhat undesirable. For example, the construction of sand-blocking reservoirs in the tributaries of the upper reaches of the Three Gorges has two major disadvantages: 1. The safety factor of these reservoirs doesit be greater than. that of the Sanmenxia reservoir. Otherwise, they will become the reservoirs of the Three Gorges. The “fire” of disasters. Second, these reservoirs cannot release the floods of the Yangtze River, otherwise the water level at the end of the reservoirs will rise and catastrophic floods will increase, which will have a great impact on Chongqing.
