Deloitte China recently released the 2017 Clean Energy Industry Report, which discusses in detail the development trends of China's clean energy industry and analyzes the opportunities and challenges faced by several subsectors, including solar energy, wind energy, new energy vehicles, solid waste treatment, water treatment and energy-saving and environmental protection new technologies.


The "13th Five-Year Plan" has set a number of targets for China's energy structure adjustment plan in 2020: the proportion of non-fossil energy consumption will increase to more than 15%, the proportion of natural gas consumption will strive to reach 10%, the proportion of coal consumption will be reduced to less than 58%, and the proportion of coal used for power generation will be increased to more than 55% of coal consumption. These imply that clean energy will play an even more important role in the future.


Zhou Jinchang, National Technology, Media and Telecommunications Industry Managing Partner of Deloitte China, said: "From the data point of view, China's total investment in clean energy in recent years has always been the world's higher, from less than $10 trillion in 2005 to more than $100 trillion in 2015, and all types of clean energy installed capacity and output also ranked first in the world. Compared with the traditional energy industry, the clean energy industry has higher requirements for research and development and investment, with correspondingly higher costs and weaker profitability, while China's clean energy industry has a higher degree of state-owned capital participation due to the greater influence of policies and subsidies. However, with the development of the industry and policy encouragement in recent years. We can see that the clean energy industry will pay more attention to the law of independent development of the market, give full play to the regulatory role of prices, and develop a more sound energy financial system."


At the same time, multi-energy complementary is also one of the main features of the future development of clean energy, energy complementary system is not only conducive to the development of clean energy, improve the proportion of new energy, but also conducive to reducing the degree of thermal power and other high-pollution, high-energy-consumption, which can be said to be multi-purpose. As of 2015, renewable energy sources accounted for a certain proportion of global power generation, including: hydropower, wind energy, biomass energy, solar photovoltaic, solar thermal power, geothermal energy and ocean energy. In the future, all of these types of renewable energy sources will be combined with non-renewable energy sources to create a cleaner, more efficiently utilized system of complementary energy generation.


From the data of 2016, although China's renewable energy generation has far exceeded that of the second and third-ranked countries, the United States and Germany, while hydroelectric power generation accounts for more than half of the renewable energy generation, and the practice in recent years has shown that hydroelectric power generation may have a certain negative impact on the ecological environment of the local waters. Therefore, China will also focus on the development of solar photovoltaic and wind power generation, which are the two major types of clean energy in the future. Yu Yang, Deloitte China's Cleantech Industry Leadership Partner, said: "Although China's wind and photovoltaic development level has been at the forefront of the world, the problem of abandoned light and wind is still serious. Therefore, in the future, the country will also pay more attention to system optimization, innovative development mode, and actively build a smart energy system. Not only to enhance the system's peak capacity as a major initiative to make up for the short board of power development, while accelerating the construction of high-quality peaking power supply, actively develop energy storage, change the scheduling and operation mode, accelerate the breakthroughs in grid balance and adaptive and other operation and control technologies, thus significantly improving the power system peak and the ability to consume renewable energy."


In addition, under the encouragement of the policy, the PV industry will synergize with the traditional industry, and play a great role in the development of poverty alleviation projects, such as "agriculture and light complementary", "fishery and light complementary" and other cooperation modes should be more productive and have significant results. Deloitte expects that in the "13th Five-Year Plan" period, the contribution of solar energy industry to China's economic output value will exceed one trillion yuan, which can provide about 7 million jobs. It is also worth mentioning that the solar industry is likely to bring more innovative investment and financing models to China. Yu Yang believes: "In the future, the better economic benefits of the photovoltaic industry will attract more social capital for investment, and more photovoltaic industry will also bring multiple benefits to society, forming a virtuous cycle."


Zhou Jinchang concluded, "Green and low-carbon development of energy is still the main object of government encouragement, and the clean energy industry has always been supported by the policy. The government still takes the development of clean and low-carbon energy as the main attack direction of adjusting the energy structure, gradually reducing the proportion of coal consumption, increasing the proportion of natural gas and non-fossil energy consumption, significantly reducing the intensity of carbon dioxide emissions and the level of pollutant emissions, optimizing the layout and structure of energy production, and promoting the construction of ecological civilization."
