On December 6, wangzhongying, deputy director of the Energy Research Institute of the national development and Reform Commission, said that China's electricity currently has enough space to accommodate the development of renewable energy. When the amount of renewable energy connected to electricity is close to 20%, it is necessary to consider the construction of the future power system, and the current proportion of China does not need the state to invest heavily in electricity

Wang Zhongying made the above statement at the 21st century low carbon China Development Summit. Wang Zhongying pointed out that on May 9 this year, the Intergovernmental Panel on climate change (IPCC) released a special report on renewable energy and climate change mitigation, which evaluated 164 development schemes around the world. This is the expert report written by the expert committee composed of 194 countries after nearly two years of work. Wang Zhongying said that the report pointed out that when the proportion of wind power integrated into local power is less than 20%, it will hardly increase the additional cost of power

according to the "wind power safety supervision report" issued by the State Electricity Regulatory Commission in Beijing recently, the proportion of wind power in China's power generation is 1.5%. Whether we have the advantages of electricity or resources, the current proportion has enough space to develop renewable energy. Wang Zhongying said

the development of renewable energy will force the reform of electricity

Shi Lishan, deputy director of the Department of new and renewable energy of the national energy administration, pointed out at the meeting that during the 12th Five Year Plan period, China will expand the proportion of renewable energy, comprehensively improve industrial capacity, especially increase the development of wind power and solar energy, and build a nuclear power based, hydropower regulated, wind power Intelligent power system with solar energy and other new energy as the main source of electricity

the power system is very important in the energy system. Wang Zhongying believes that in the future, the power system should be able to cope not only with the volatility of users, but also with the volatility of power generation, that is, for renewable energy, such as intermittent wind power

for the future power system, Wang Zhongying said that it is possible to accept 100% renewable energy. More renewable energy is unsafe. I think it's wrong. First of all, we need to change our ideas. Wang Zhongying pointed out that if renewable energy can be 100%, there will be a new electric energy system. But what is the cost of the new power system? We need to do research

according to its introduction, the German Energy Agency spent three years studying the energy transformation strategy around the core theory of 100% renewable energy, and found that by 2030, the electricity transformation of 100% renewable energy will increase the electricity price cost of end users by two euro cents per kWh

Wang Zhongying said that the reform of the power system has been called for many years, but the adjustment of the benefit distribution mechanism is too difficult, and the large-scale transcendental development of renewable energy in the future will promote the reform of the power system and energy transformation. By 2030, when renewable energy reaches a certain proportion and the transformation of power system is successful, we will have an economically stable and sustainable energy system, and then we can develop renewable energy on a larger scale. Wang Zhongying said

Shi Lishan believes that when China's energy consumption reaches its peak in 2030 and 2040, it can be based on nuclear power, regulated by hydropower, dominated by new energy, supplemented by coal-fired power. The main features of providing the future are as follows: 1. A systematic energy of 3 billion tons of standard coal. At the same time, focus on building smart electricity, which will bring revolution to China's power management system

urbanization energy consumption increased by 35% year-on-year during the Eleventh Five Year Plan period

Li Xinmin, an inspector of the Department of pollution prevention and control of the Ministry of environmental protection, said at the meeting that China's technological progress in the field of energy is remarkable, and energy efficiency is improving at a rate of 12% per year. However, in recent years, heavy chemical industry and high energy consumption industry have developed rapidly, and changes in the industrial structure have offset or slowed down the downward trend of GDP energy consumption intensity

according to the latest statistical data, in the first half of 2011, the frequency of acid rain across the country. Cities with a frequency of more than 25% are mainly distributed in most areas of Zhejiang, Fujian, Jiangxi, Shanghai, Hunan and Chongqing. Cities with a frequency of more than 75% are mainly concentrated in Zhejiang, the east of Jiangxi and the southwest of Chongqing. Li Xinmin said that this reflects the development of local economy. The increase of coal consumption has brought about the growth of acid deposition

in addition, the emission of nitrogen oxides is also increasing at the same time. Li Xinmin pointed out that during the 14 years from 1996 to 2009, for each percentage point increase in the urbanization rate, about 195000 tons of nitrogen oxides were emitted, while the increment of nitrogen oxides brought by the development of motor vehicles reached about 86000 tons

after analyzing the energy consumption and pollutant emission in the past 14 years, the Environmental Planning Institute of the Ministry of environmental protection found that the contribution of urban development to the increase of energy consumption increased. The development of urbanization has actually promoted the increase of energy consumption and pollutant emissions. Li Xinmin said

according to the analysis, during the 14 years from 1996 to 2009, the urbanization of the experimental machine with constant displacement rate control characteristics increased by an average of one percentage point, which required an additional 49.4 million tons of standard coal. The average energy consumption during the Ninth Five Year Plan period was 41.68 million tons, and the average energy consumption during the Tenth Five Year Plan period was 46.42 million tons. By the Eleventh Five Year Plan period, it had risen to 62.74 million tons of standard coal, an increase of 35% year-on-year
