With global warming,extreme weather and climate events occur frequently.Addressing climate change and accelerating the energy transition bears on the destiny of mankind,and action is urgent.China has put forward the"two-carbon"goal to alleviate climate change and achieve the energy transition,and has actively promoted it.On December 23,2023.Du Xiangwan,academician of the Chinese Academy of Engineering,put forward constructive suggestions on China's energy transformation at the expert innovation lecture jointly hosted by the Ministry of Human Resources and Social Security and the China.
In order to realize China's energy transformation,we must first need to re-understand China's energy and resource endowment."Rich in coal", "lack of oil" and "less gas" can not accurately describe the characteristics of China's energy resources.Compared with the world,China's per capita coal reserves only account for 67% of the world average.Despite China's large coal reserves,the technically exploitable coal storage ratio is only about 40 years old."Coal is a valuable resource rich in carbon, but it is not renewable."Du Xiangwan stressed that while contemporary people are using coal well,they should also prepare early for the future.There is a time limit to rely on coal.
Fortunately,China is rich in renewable energy resources,which has laid a good foundation for the low-carbon energy transition.At present,China's installed capacity of hydropower,wind power,solar power generation and nuclear power under construction are the first in the world.By 2022,China's installed renewable energy capacity reached 1.213 billion kW,accounting for 47.3% of the country's total installed power generation capacity; renewable energy generation capacity reached 2.7 trillion KWH, accounting for 31.6% of the total electricity consumption.
How to use these renewable energy sources efficiently? Experts found that: 1 degree of electricity, the cost of eastern spontaneous generation is lower than the cost of west to east."This conclusion is very important. It is necessary to 'take around' and 'come from afar', but the central and eastern regions should first 'take around' and improve their self-sufficiency rate."Du Xiangwan gave a key hint. Self-produced direct selling and electricity in the people can cultivate a large number of "consumers", which can not only improve the local energy self-sufficiency rate, independence and security, but also alleviate the impact of a high proportion of renewable energy on the power grid. Thus, the low-carbon transition and energy security go hand in hand.
Low-carbon energy has become a global consensus on the future of mankind. The "two-carbon" strategy proposed by China is the only way to follow the trend of green development and promote high-quality economic and social development.
Du Xiangwan believes that the realization of the "two-carbon" goal is a complex system engineering, which is a decades-long scientific transformation process. Under the general trend of energy transformation, it is necessary to pay attention to the innovation and development ability of new energy technology and the control, recycling and recycling of new energy key materials and mineral resources, as well as the invention and innovation ability of material science. At the same time, the policy should prevent "one size fits all" simplification, but also to prevent the ineffective transformation.
Carbon neutrality is an important milestone, but it is only a milestone, not an end point. Du Xiangwan said: " In 2060, whether China or the world, human society needs to develop, but still need to rely on the support of future energy. But as we move into the future and look back, we can better understand the significance and historical position of the 'two-carbon' goal."
