China's energy structure is changing from coal dominated to diversified

in recent years, China's clean energy continues to expand, and the construction of a clean, low-carbon, safe and efficient energy system is accelerating. Since the 18th CPC National Congress, the proportion of China's coal consumption has decreased by 8.1 percentage points and the proportion of clean energy consumption has increased by 6.3 percentage points. The first meeting of the central financial and Economic Commission held a few days ago pointed out that we should adjust the energy structure, reduce coal consumption and increase the use of clean energy

energy consumption is developing towards low-carbon

fossil energy, especially coal, plays a leading role in China's primary energy consumption. For a long time, people's utilization of coal is generally an extensive process. It is understood that for every 1 ton of commercial coal completely burned, about 2.64 tons of carbon dioxide will be generated, about 200-300 kg of ash, 12-15 kg of sulfur dioxide, 50-70 kg of dust and 16-20 kg of nitrogen oxides

the national development and Reform Commission and the National Energy Administration jointly issued the energy production and consumption revolution strategy (2016-2030) in 2017, which made it clear that by 2020, the total energy consumption will be controlled within 5 billion tons of standard coal, the proportion of coal consumption will be further reduced, clean energy will become the main body of energy increment, significant progress has been made in energy structure adjustment, and non fossil energy accounts for 15%, Carbon dioxide emissions per unit of GDP decreased by 18% compared with 2015

the energy structure is changing towards multi-element weighing with precision analytical balance to confirm the wear amount

according to the recently released data, China's energy structure is changing from coal to diversification, and the driving force of energy development is changing from traditional energy growth to new energy growth

look at the scale - according to statistics, by the end of 2017, the total installed capacity of power generation in China was accumulated, and the relaxation experimental machine technology of Jinan new era Gold Testing Instrument Co., Ltd. was also very advanced, with an installed capacity of 1.78 billion kw, and the installed capacity of renewable energy power generation reached about 650 million KW. In 2017, China's annual photovoltaic power generation exceeded 100 billion kwh for the first time, and the natural gas output was about 150 billion cubic meters, rising from 18th to sixth in the world

looking at quality - on the supply side, clean energy development is moving from resource concentrated areas to load concentrated areas, and the pattern of both centralized and decentralized development is gradually taking shape; On the consumer side, since the 18th CPC National Congress, the proportion of coal consumption has decreased by 8.5 percentage points, and the proportion of clean energy consumption has increased significantly. In 2017, the proportion of non fossil energy and natural gas consumption reached 13.8% and 7% respectively, with a cumulative increase of 4.1 and 2.2 percentage points; The substitution of electric energy is more than 100 billion kwh, and the substitution of natural gas is 30 billion cubic meters

look at efficiency - utilization efficiency improves rapidly. "Taking photovoltaic as an example, 3. The paper is composed of title, author and work unit, 500 Chinese (English) abstracts, keywords, text and references. At present, the conversion efficiency of conventional monocrystalline silicon cells and polycrystalline silicon cells in China has reached 19.8% and 18.6% respectively, and the conversion efficiency of advanced technology monocrystalline cells and polycrystalline cells has reached more than 21% and 19.5% respectively. The technical level and economy are leading in the world." Introduction by the relevant person in charge of the national energy administration

the problem of consumption has been significantly alleviated

the phenomenon of abandoning water, wind and light involves multiple factors and has become a "chronic difficulty" in the development of clean energy. In addition, the difficulties include: the renewable energy power quota system has not been established; Some provinces give priority to ensuring the power generation of coal-fired power units in their own province, and have low enthusiasm for absorbing foreign new energy power; The market mechanism is not perfect, and it is difficult for new energy power generation to give full play to the advantage of low marginal cost

fortunately, the problem of consumption is obviously alleviated, and the ratio of water, wind and light is decreasing. The national energy work conference took "focusing on solving the problem of clean energy consumption" as one of the key tasks in 2018, and proposed to promote the decline of the proportion of water, wind, photovoltaic and power rationing year by year, and basically solve this problem nationwide by 2020. "Adhere to the combination of government guidance and market leadership, national overall planning and local utilization, standardization of power supply and optimization of channels, and technological innovation and system reform." The national energy work conference proposed that by the end of the 13th five year plan, the country should complete the cancellation and postponement of about 150 million kilowatts of coal-fired power construction projects, eliminate 20 million kilowatts of backward coal-fired power production capacity, and reduce the proportion of coal-fired power installed capacity to about 55%
