The rapid expansion of renewable energy and trillions of new investment are on the road. The continuous expansion of clean energy and the vigorous development of green economy will become one of the main forces driving China's economic growth in the future

since the 18th CPC National Congress, China's energy structure has been significantly optimized, which has played an important role in promoting the energy revolution and protecting the ecological environment. By the end of last year, the installed capacity of renewable energy power generation had reached 570million kW, accounting for about 35% of the total installed capacity of electricity; The utilization of non fossil energy accounted for 13.3% of the total primary energy consumption, an increase of 3.9 percentage points over 2010

the 13th five year plan for renewable energy development (hereinafter referred to as the plan) issued by the national development and Reform Commission last December proposed that during the 13th Five Year Plan period, China's new investment in renewable energy will reach 2.5 trillion yuan, an increase of nearly 39% over the 12th Five Year plan period. By 2020, the annual utilization of all renewable energy will reach 730 million tons of standard coal. Among them, the utilization of commercial renewable energy is 580 million tons of standard coal

the installed capacity of photovoltaic power generation leads the world.

at present, the installed capacity of hydropower, wind power and photovoltaic power generation in China has ranked first in the world

according to the data provided by the national energy administration, since the 18th CPC National Congress, China has increased the installed capacity of hydropower by about 83million kW. It is estimated that the total installed capacity will be about 340million kW by the end of 2017, and the annual power generation will exceed 1.1 trillion kwh. In the past five years, China has started and put into operation a number of large hydropower stations with more than 3million kW, such as Xiluodu on the Jinsha River and Xiangjiaba. Among them, the installed capacity of Xiluodu Hydropower Station ranks third in the world

c919 also adopts a large number of composite materials and new aviation alloy wind power. Since 2012, China's new wind power installed capacity has ranked first in the world for four consecutive years. By the end of last year, the cumulative installed capacity of wind power had increased by 87.58 million KW, becoming the third largest power source after coal power and hydropower

in terms of photovoltaic, since 2013, the installed capacity has increased by more than 1000 for four consecutive years. "The use of graphene in power cables may slightly increase the product cost by million KW. At the end of last year, the cumulative installed capacity of photovoltaic power generation in China reached 77.42 million KW, ranking first in the world for two consecutive years.

the National Energy Administration said that clean and low-carbon energy will be the main body of energy supply increase during the 13th Five Year Plan period. China will continue to promote the large-scale development of non fossil energy and accelerate the utilization of natural gas. While doing a good job in the clean and efficient utilization of coal, we plan to build a number of major hydropower and nuclear power projects, steadily develop renewable energy such as wind power and solar energy, vigorously develop natural gas distributed energy and natural gas peak shaving power stations, and actively promote the replacement of coal and oil with gas in civil, industrial and transportation fields

the plan proposes that by 2020, the installed capacity of all renewable energy power generation will be 680million kW, with a power generation capacity of 1.9 trillion kwh, accounting for 27% of the total power generation capacity; All kinds of renewable energy heating and civil fuels replace fossil energy by about 150 million tons of standard coal; The electricity price of wind power projects can compete with the local coal-fired power generation platform, and the electricity price of photovoltaic projects can be equivalent to the electricity sales price

with the rapid expansion of renewable energy, China has also accelerated the pace of clean and efficient utilization of traditional energy

the upgrading and transformation of energy conservation and emission reduction in coal and electricity are advancing steadily. According to the data provided by the national energy administration, by the end of last year, China had completed a total of 450million kW of ultra-low emission transformation and 460million kW of energy-saving transformation, accounting for 77% and 73% of the 2020 target respectively. At the same time, the level of clean and efficient utilization of coal has been significantly improved

at the same time, significant progress has been made in electric energy substitution. In 2016, China's sales of new energy vehicles ranked first in the world with 507000 units. In order to adapt to the gradual popularization of new energy vehicles, China has accelerated the development of charging infrastructure industry. By the end of April this year, a total of 171000 public charging piles had been built nationwide

Shu Yinbiao, chairman of Guodian, told China first finance and economics that the Intercity Express charging station has formed a pattern of "six vertical, six horizontal and two ring roads", covering 14000 kilometers, 13 provinces and 95 cities

great potential to reduce energy consumption

at present, China has great market potential in the use of energy-saving products

"China's central air conditioning market reaches 70billion yuan a year, but energy-saving central air conditioning (reaching the national first-class energy efficiency) accounts for about 3%, not more than 5% Yang Baolin, general manager of the central air conditioning division of Haier Group's air conditioning products group, said in an interview with first finance

Yang Baolin said, for example, "after a five-star hotel in Zhuhai adopts the magnetic levitation heat recovery energy-saving solution, it saves 504000 kwh of electricity and 430000 yuan of electricity every year. The energy consumption of the hotel's central air conditioning accounts for 40% - 60% of the hotel's energy consumption, while the electricity charge accounts for 30% of the operating cost - the electricity charge of the central air conditioning is very important to the income of the hotel, and these saved electricity charges are the net profit of the hotel."

the current situation of the energy-saving air conditioning industry is an epitome of the energy-saving product market. There is still much room for development in improving energy efficiency in China. Taking Beijing, which has the lowest energy consumption per 10000 yuan of GDP in China, as an example, the latest statistics show that in 2016, the energy consumption per 10000 yuan of GDP in Beijing was 0.2835 tons of standard coal, a year-on-year decrease of 4.79%; The water consumption per 10000 yuan GDP was 15.8 cubic meters, a year-on-year decrease of 4.79%

Zhou Rui, director of the energy and Resources Statistics Division of the Beijing Municipal Bureau of statistics, said in an interview with China business that although Beijing's energy utilization rate is at the leading level in the country, there is still a certain gap compared with developed countries

"In terms of energy efficiency, Beijing's energy consumption per 10000 yuan GDP is 1.5 times that of New York State and 5.9 times that of Tokyo. There is still room for further improvement in Beijing's energy conservation and consumption reduction; in terms of energy use structure, through the promotion of coal to electricity and coal to gas, Beijing is relatively optimized nationwide. In 2016, the proportion of coal energy consumption was 9.8%, and the proportion of coal consumption in some advanced countries was less than 5%; in terms of renewable energy, the proportion of utilization should be increased. In 2016, Beijing Renewable energy accounts for 6%, more than 10% in developed countries and nearly 20% in Germany. " Zhou Rui said

when "green" and "innovation, coordination, openness and sharing" are positioned as "development concepts" and run through all fields and links of economic and social development during the 13th five year plan, green development is expected to become a new driving force for economic growth

Cao Mingdi, a researcher at the ecological finance research center of Renmin University of China, believes that to strengthen green, circular and low-carbon development, it is necessary to reduce the material consumption per unit output and improve the green content of economic development

Cao Mingdi once wrote that we should strengthen the management of binding indicators, implement the action of double control of the total amount and intensity of energy and water consumption, construction land and so on, and improve the standards of energy conservation, water conservation, land conservation, material conservation and mineral conservation; Promote circular production and industrial circulation in which the enterprise circulates and is perpendicular to the axis. 3. Equip all experimental accessories required for wood-based panel physics experiments; The circular combination and the circular transformation of the park will promote the transformation of the traditional linear growth mode of "resources products wastes" into a sustainable development system of closed-loop material flow; Increase the proportion of non fossil energy, promote the clean and efficient utilization of fossil energy such as coal, strengthen the construction of energy storage and smart electricity, improve the industrialization level of electric vehicles, improve the building energy conservation standards, implement the demonstration project of near zero carbon emission areas, and realize the active and effective control of carbon emissions

the plan states that during the "13th five year plan" period, through continuous improvement of renewable energy support policies, innovation of renewable energy development methods and optimization of development layout, we will accelerate the promotion of renewable energy technological progress and cost reduction, further expand the scale of renewable energy applications, increase the proportion of renewable energy in energy consumption, and promote the optimization and upgrading of China's energy structure
