Stop burning coal for 24 hours! This country, which is the first to use coal power in the world, may be the first to bid farewell to coal

Abstract: in the early years, China's coal consumption of elastic coefficient, namely elastic Young's modulus, was still very large. It is reported that as of 2016, China's coal-fired power generation accounted for the first in the world, accounting for 67%, far higher than the proportion of 29% in the United States and 17% in Europe and the United States. In China, wind power generation accounts for 3 Gao Yong, party secretary and Secretary General of China Textile Industry Federation, said that 3% and solar power generation accounted for 0.7%, far lower than the data of Europe and the United States

in 2015, the last deep coal mine in Britain was closed, and the media at that time mostly called it "the end of an era". On Friday (April 21), the National Grid announced that it would stop burning coal for 24 hours, which is the first time in 135 years that the UK has not used coal power for a day, which also means that the UK is further towards the goal of withdrawing from coal use

since Edison opened the Holborn viaduct power station in London in 1882, coal power has been the standard configuration of British culture. On the one hand, this enabled Britain to carry out the first industrial revolution, on the other hand, the serious environmental pollution it brought also caused great controversy

in 1952, the London smog incident made the British government aware of the heavy environmental harm caused by coal combustion. After investigation and research, the government introduced the clean air act in 1956, which stipulated measures such as banning black smoke emission, raising the height of chimneys, establishing smoke-free areas, transforming household fireplaces in smoke-free areas, and replacing coal fuels

in the 1970s, the discovery of North Sea oil fields prompted the British government to change the energy structure

in the 1980s, due to the increasingly poor competitiveness of domestic coal, the conservative government with Thatcher as prime minister came to power and increasingly wanted to get rid of the "hot potato" of the national coal industry. In the next few years, 36 high-cost mines were closed

in the 1990s, there were only 50 mines left in Britain, and the British coal company also proposed to close 31 more mines. Although it was opposed by all sectors of society, only 20 mines were left in the end, and the output also fell to 50million tons, accounting for only 7% of the final energy consumption structure

with the efforts of continuously closing mines and reducing production in the past decades, the total amount of deep coal mining in the UK fell from 7.496 million tons in 2009 to 3.685 million tons in 2014, almost halving

in 2015, kellingley, the last deep well coal mine in Britain, was officially closed. The British government also announced that all coal-fired power plants would be shut down by 2025

after the closure of the plant, the consumption of coal in Britain is also declining steadily. Data showed that the use of coal-fired energy fell to an all-time low in the second quarter of last year. In September last year, coal only accounted for 5.8% of the energy produced in the quarter, down 20% from the same period in 2015

while the proportion of traditional coal energy has decreased, the use of renewable energy in the UK is increasing

Duncan Burt, head of the UK national electricity supply company, told the media that half of the electricity in the UK currently comes from natural gas power generation, and 30% of the electricity comes from renewable energy and trading electricity

it seems that Britain is still promising to become the first country that does not use coal

in addition, China also attaches great importance to the issue of coal power, and the reduction of coal production has also become a key area of economic work for two consecutive years

in the early years, China's coal consumption was still very large. It is reported that as of 2016, China's coal-fired power generation accounted for the first in the world, accounting for 67%, far higher than the proportion of 29% in the United States and 17% in Europe and the United States. In China, wind power generation accounts for 3.3% and solar power generation accounts for 0.7%, which is far lower than the data of Europe and the United States

however, since last year, efforts have been made to reduce coal production capacity and develop clean energy. According to the energy production situation of the National Bureau of statistics in February this year, the raw coal output in 2016 was 34 The operating temperature is limited to 100 million tons, a decrease of 9.0% over the previous year, which is the third consecutive year of decline since the raw coal output reached 3.97 billion tons in 2013

in addition, the data also showed that in 2016, in addition to coal consumption decreased by 4.7%, crude oil consumption increased by 5.5%, natural gas consumption increased by 8.0%, and power consumption increased by 5.0%. Among them, the consumption of clean energy such as hydropower, wind power, nuclear power and natural gas accounted for 19.7% of the total energy consumption, up 1.7 percentage points

the national energy administration also issued the "13th five year plan" for power development last November, which "controls the planned capacity of coal-fired power within 1.1 billion kw. 9. When used, it must be operated according to the procedures specified in the instructions". The national development and Reform Commission also said in April this year that it would reduce the planned electricity consumption of existing coal-fired power generation enterprises year by year

as the first industrial revolution swept the world, the transformation of waste coal into clean energy will also become the mainstream. However, judging from the fact that thermal power generation still accounts for the majority in China, there is still a long way to go to change such a large volume
