The International Energy Agency recently published the coal market Interim Report 2017, global coal consumption of 4.32 billion tons of oil equivalent, nearly 44 million tons of oil equivalent of oil consumption. Under the impetus of the huge demand of the emerging markets, the proportion of coal in the global energy mix has increased year by year, it is possible to replace oil in the next 10 years, to become the primary source of global energy.
 
With the accelerated process of industrialization and urbanization in China, coal consumption will continue to increase. At the same time, taking into account the the domestic rich in coal, lack of oil, less gas energy endowment, difficult to change the status of coal as the main energy in China for a longer period of time to come.
 
In this regard, the analysis of Liu Ye, Shanxi Academy of Social Sciences, Institute of Energy Economics, Energy Policy Research Office: 'coal-based, diversified development' is the basic orientation of China's energy strategy, taking into account the adjustment of energy structure, environmental protection, control and PM2. 5 pollution and other factors affect the development of clean coal technology, to promote the efficient and clean use of coal resources will be the trend of the times. "
Coal pollution red light
 
Pollutants emitted into the atmosphere in the process of production and utilization of coal dust, sulfur dioxide, carbon dioxide, nitrogen oxides, 85% carbon dioxide and 60% of nitrogen oxides from the combustion of coal. "Liu Ye said.
 
Liu Ye told reporters that China's coal production is used as a fuel for about 80%, while the proportion of China's coal resources, high-sulfur, high-ash coal, most of the raw coal ash content of about 25%, are ash coal; belongs in high raw coal sulfur coal, about 13% of the sulfur content greater than 2%.
 
Domestic energy consumption has long been over-reliance on coal, coupled with the neglect of environmental pollution in the past, the use of coal led to the intensification of the atmospheric pollution. The use of coal emissions of carbon dioxide and other harmful gases, increasing pressure on our response to climate change.
 
Not only that, the coal mining process will pose a threat to the environment. The destruction of water resources caused by China's coal mining, gas emissions, coal gangue stockpiling, surface subsidence, serious damage to the ecological environment of mining.
 
Liu Ye pointed out that the high methane content of most of our coal fields, the release of methane in coal mining accounts for about 20% of the world's emissions, the greenhouse effect caused by methane is 20-60 times more carbon dioxide.
 
The increase in the greenhouse effect will lead to climate anomalies. Methane consumption of ozone in the stratosphere, ozone reduction irradiation increased to the ultraviolet light on Earth, its results may be induced by a variety of diseases affecting human health. "Liu Ye said.
 
She believes that in this case, vigorously develop clean coal technology, clean and efficient conversion of coal to achieve a low-carbon use of high-carbon energy, China, the world's largest coal production and consumption country, more realistic and urgency.
