Multi-energy complementation will be the main feature of clean energy development

Deloitte China recently released the 2017 Clean Energy Industry Report, which discusses the development trend of China's clean energy industry in detail, and analyzes the opportunities and challenges they face from several sub-industries, including solar energy, wind energy, new energy vehicles, solid waste treatment, water treatment and new technologies for energy conservation and environmental protection.

The "13th Five-Year Plan" has formulated a number of indicators for China's 2020 energy structure adjustment plan: 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 increase to more than 55%. This means that clean energy will play a more important role in the future.

Deloitte China National Science and Technology Zhou Jinchang, executive partner of the media and telecommunications industry, said: "From the perspective of data, China's total investment in clean energy has always been higher in the world in recent years, from less than 10 trillion US dollars in 2005 to more than 100 trillion US dollars in 2015, and the installed capacity and output of all kinds of clean energy have 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, higher costs and weak profitability. However, due to The impact of policies and subsidies is greater, and the participation of state-owned capital is higher. However, with the development of the industry and the encouragement of policies in recent years. We can see that the clean energy industry will pay more attention to the law of market independent development, give full play to the role of price regulation, and develop a more sound energy financial system. "

At the same time, multi-energy complementation is also one of the main features of the development of clean energy in the future. The energy complementation system is not only conducive to the development of clean energy, increase the proportion of new energy, but also conducive to reducing the degree of high pollution and high energy consumption such as thermal power. By 2015, renewable energy accounted for a certain proportion of global power generation, including hydropower, wind energy, biomass energy, solar photovoltaic, photothermal power generation, geothermal energy and marine energy. In the future, these kinds of renewable energy will combine with non-renewable energy to create a cleaner and more efficient energy complementary power generation system.

According to the data in 2016, although China's renewable energy power generation has far exceeded the second and third place of the United States and Germany, hydropower accounts for more than half of the renewable energy power generation, and recent practice shows that hydropower may have a certain negative impact on the ecological environment of local waters. Therefore, China will also focus on the development of solar photovoltaic and wind power generation, two major categories of clean energy in the future. Yu Yang, the leading partner of Deloitte China's clean technology industry, said: "Although China's development level of wind energy and photovoltaic power has been at the forefront of the world, the problem of light and wind abandonment is still serious. Therefore, in the future, the country will also pay more attention to system optimization, innovate development models, and actively build smart energy systems. It will not only take improving the peak shaving capacity of the system as a major measure to complement the shortcomings of power development, but also accelerate the construction of high-quality peak shaving power, actively develop energy storage, and change the dispatching operation mode Quickly break through the operation control technologies such as grid balancing and adaptive, thus significantly improving the power system's ability to regulate peak load and absorb renewable energy. "

In addition, under the encouragement of the policy, the photovoltaic industry will develop in coordination with the traditional industries and play a huge role in the implementation of poverty alleviation projects, such as "agricultural and photovoltaic complementation", "fishing and photovoltaic complementation" and other cooperation modes, which have survived and achieved remarkable results. Deloitte expects that during the "13th Five-Year Plan" period, the contribution of solar energy industry to China's economic output value will exceed trillion yuan, providing about 7 million jobs. More importantly, the solar energy industry is likely to bring more innovative investment and financing models to China. Yu Yang said: "In the future, the better economic benefits of the photovoltaic industry will attract more social capital to invest, and more photovoltaic industries will also bring multiple benefits to the society, forming a virtuous circle."

Zhou Jinchang concluded: "Green and low-carbon development of energy is still the main target of the government, and the clean energy industry has always been supported by policies. The government still takes the development of clean and low-carbon energy as the main 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 pollutant emissions, optimizing the layout and structure of energy production, and promoting the construction of ecological civilization Set.
