Since fossil fuels are currently a major part of the world's primary energy sources, the amount of mining and combustion consumption is large, and the environmental impact is also of concern.
The most typical environmental impact of the mining process is coal mining, including damage to the land, damage to the village, and impact on water resources. According to incomplete statistics, an average of 0.2 hectares of farmland collapsed per ton of coal has been destroyed so far, with an average annual collapse of 20,000 hectares. China's buildings have more than 4.8 billion tons of coal under pressure, of which 2/3 of the villages are under pressure.
In the plain areas of Shandong, Hebei, Henan, Anhui and Jiangsu provinces, there are 1,100 coal-pressing villages, with more than one million living villagers. The impact of water pollution caused by mining on the ecological environment is also extensive. On average, 2 tons of raw coal is required to be discharged per ton of raw coal. In some areas, due to serious pollution of water sources and rivers and lakes, residents use water. shortage.
The environmental impact of fossil fuels during their utilization is mainly caused by various gases and solid wastes during combustion and waste heat from power generation. There are two main aspects to the environmental impact of pollutants produced by fossil fuels. The first is global climate change. The carbon in the fuel is converted into carbon dioxide into the atmosphere, causing the concentration of carbon dioxide in the atmosphere to rise, resulting in an increase in the greenhouse effect, changing the global climate and imbalance of ecological balance. The second is thermal pollution. The “remaining heat†left by the power station is discharged into rivers, lakes, the atmosphere or the ocean, which in most cases causes thermal pollution. For example, when the waste hot water enters the waters, its temperature is on average 7-8 °C higher than the temperature of the waters, so that the organisms leave the waters.
