How to promote the energy revolution

recently, the fourth Energy Forum and the international high level Forum on Engineering Science and technology development strategy, hosted by the Chinese Academy of engineering and the national energy administration, closed in Beijing. At the forum, academicians, government officials, domestic and foreign experts and scholars exchanged views on how to promote the energy production and consumption revolution. Xie Kechang, an academician of the Chinese Academy of engineering, pointed out that the energy revolution cannot be achieved overnight. He predicted that by 2050, the proportion of fossil energy in China will drop from nearly 90% today to 40% in stages, and the proportion of non fossil energy will rise to 30%

at the end of 2012, the report of the 18th National Congress of the Communist Party of China first proposed "promoting the revolution of energy production and consumption". As the highest advisory body in China's engineering science and technology industry, the Chinese Academy of engineering began to carry out strategic research on this topic in May 2013 to avoid unnecessary losses. The research result of academician Xie Kechang's team that the ground bar steel melts waste with medium frequency furnace points out that the energy revolution can be divided into three steps, and we need to stop checking for these two key points

academician Xie Kechang's team predicts that the first stage of the energy revolution will be from now to 2020. This stage is the period of energy structure optimization. The main connotation is the clean, low-carbon, safe, efficient and sustainable development and utilization of coal, eliminating backward production capacity and improving the concentration of coal utilization. It is predicted that by 2020, the proportion of coal, oil and gas, and non fossil energy will reach 60%, 25% and 15%. The second stage is from 2020 to 2030, which is a period of change in the energy field. The strategy of replacing coal with clean energy, especially renewable energy, is mainly implemented. It is expected that by 2030, the proportion of coal, oil and gas, and non fossil energy consumption will reach 50%, 30% and 20%. The third stage is from 2030 to 2050, which is the finalization period of the energy revolution. At that time, a new energy system of "five modernizations" needs to be formed, namely, rationalization of demand, greening of development, diversification of supply, intelligent allocation and efficient utilization. It is estimated that coal, oil and gas and non fossil energy account for 40%, 30% and 30% respectively

the research conclusion of academician Xie Kechang's team and the viewpoint put forward by Nur Baikeli, director of the national energy administration at the forum illustrate the same situation: coal will still be the main energy in China for a long time in the future

Nur Baikeli pointed out in the report: "in the past two years, we have promoted the supply side structural reform, and the achievements of coal de capacity are obvious to all. However, from the perspective of our country's resource endowment, coal will still be the main energy in China for a long time in the future, which is our most basic national condition." Nur Baikeli believed that it would be unrealistic to talk about China's energy transformation and China's energy security without coal

liujizhen, academician of the Chinese Academy of engineering, popularly summarized the current situation of China's energy resources with "lack of oil and gas, coal and electricity". Therefore, he advocated that "thermal power generation should be done" and believed that thermal power generation could be integrated into a clean, low-carbon, safe and efficient modern energy system through technological change

as an expert in the field of coal chemical industry, academician Xie Kechang emphasized on the forum for many times: "the number of clean and efficient coal experiments will be automatically reduced by 1 and displayed on the times display. Carbon is also a clean energy." At the same time, Nur Baikeli also pointed out: "now the voice of decarbonization is getting louder and louder, but I think decarbonization is not de coal, let alone de industrialization."

at present, fossil energy still dominates the world energy composition. But in terms of increment, the huge world energy system is gradually turning to renewable energy. The chart brought by Yang Lei, senior adviser to the director of the International Energy Agency, shows that after entering the new century, the proportion of renewable energy to meet the demand for energy growth is increasing: from the growth of global energy consumption from 2000 to 2010, 47% of the growth comes from coal, and only 12% from renewable energy. From 2010 to 2016, the proportion of renewable energy to meet the energy growth demand reached 32%, while coal only increased by 10%

another chart of Yang Lei shows that low-carbon energy will really support the global energy increment in the next 25 years. In addition to nuclear power, about a quarter of these energy growth sources are all renewable energy, and about a third of the growth of renewable energy comes from China. "China has become the locomotive of clean energy development, which has become a reality," he said

at the same time, Yang Lei also stressed that the global energy investment report released by the International Energy Agency has a landmark event: last year, the investment in electricity exceeded the investment in all upstream fossil energy. This is the first time that direct investment in electricity has surpassed investment in fossil energy
