In the next 15 years, wind power and photovoltaic power generation will drive an investment of 5.4 trillion
on April 11, Greenpeace, an international environmental protection organization, held a media conference and released the report "synergy benefits of wind power and photovoltaic power generation in China", which quantitatively and qualitatively evaluated the energy, environmental, economic and social benefits of wind power and photovoltaic power generation in China for the first time
the report points out that by 2020, China will achieve the strategic goal of energy development that the proportion of non fossil energy in primary energy consumption will reach 15% by 2020 and 20% by 2030. The large-scale development of renewable energy such as wind power and photovoltaic power is an important way to achieve this goal. However, China's wind power PV has encountered some bottlenecks in the process of rapid development. The problem of abandoning wind and light has become increasingly prominent, and the number of power generation hours has not been effectively guaranteed. One important reason is that the significant benefits of wind power PV in many aspects such as energy, environment, economy and society have not been well known by the society, but have been underestimated or even ignored. Not only has it failed to reach a consensus in the whole society, but also there are many misunderstandings, Even distortion of facts
for example, without considering the external environmental pollution cost of coal-fired power generation, blindly emphasizing the subsidy of renewable energy is an unbearable task, but ignoring the declining cost of renewable energy and the subsequent declining subsidy level while replacing coal to reduce environmental pollution, as well as China's use of less subsidies, achieving renewable energy 5 Calibration is carried out by the measurement department for the large-scale development and utilization of raw energy; Regardless of the fundamental change of the power system dominated by fossil energy, it blindly emphasizes the volatility of renewable energy and the consequent merger costs, but 2) the equipment ignores the volatility of renewable energy during the test run, and there are no technical obstacles, and it can promote the development of electricity in a more flexible and intelligent direction
the report points out that there are still many obstacles in China's current institutional mechanisms and policy environment, which are not conducive to the efficient development of renewable energy and the realization of its goals. Understanding the synergistic benefits of wind power and photovoltaic power generation is the basis for condensing social consensus and removing obstacles to the development of renewable energy. In this regard, Li Junfeng, former director of the National Center for strategic research and international cooperation on climate change, believes that only with a comprehensive understanding of the synergistic benefits of wind power and photovoltaic, can we more effectively promote energy transformation from top to bottom and get rid of dependence on fossil energy as soon as possible
according to the report, after 2020, the growth of China's power system will be dominated by wind power, photovoltaic power and gas power. In order to achieve the goal of 20% non fossil energy by 2030, the annual growth rates of wind power and photovoltaic power generation will reach more than 10% and 20% respectively. It is expected that the annual utilization hours of wind power will remain at 2000~2100 hours and the annual utilization hours of photovoltaic power will remain at 1200~1300 hours in the next 15 years
in terms of energy efficiency, the energy recovery period of wind turbine and photovoltaic system is mainly affected by two factors: energy consumption and power generation in the whole life cycle. The energy recovery period of wind power is 0.7 years and that of photovoltaic is 1.6 years. However, the energy recovery period can affect the cost of wind power generation to a certain extent. By 2030, the cost of wind power and photovoltaic power generation in China will be reduced by 20% and 40% respectively compared with 2015. Considering the uncertainty of future technology, the unit cost of wind power and photovoltaic power generation may be reduced to a greater extent
in terms of environmental benefits, the full life cycle environmental damage cost of the wind power industry is 0.000101 yuan/kWh, and the full life cycle environmental damage cost of the photovoltaic power generation industry is 0. The relevant information of Jinan new era Gold Testing Instrument Co., Ltd. is introduced below Yuan/kWh, corresponding to the environmental external benefit of wind power and photovoltaic power generation for coal power is 0.159 yuan/kWh. By 2030, China's combined wind power and photovoltaic annual power generation will reach 980.2 billion kWh and 540 billion kwh respectively, and the environmental benefits of power generation will be about 294 billion yuan and 162 billion yuan respectively
in terms of economic benefits, wind power and photovoltaic industries span the secondary and tertiary industries, involving many fields such as new materials, manufacturing, power and automatic control. From 2016 to 2030, China's wind power and photovoltaic power generation has attracted a total investment of about 5.4 trillion yuan and a total GDP growth of about 14.3 trillion yuan
