The report of the Twentieth National Congress of the Communist Party of China proposed to "strengthen the construction of security capacity in key areas, and ensure the security of food, energy resources, and important industrial chain supply chain", and made it clear that ensuring the security of energy resources is an important part of maintaining national security capacity. Energy is a scarce resource to maintain the national economy and the people's livelihood, and an element of national competition. The world today is experiencing unprecedented changes in a century. The global geopolitical, economic, scientific and technological, and governance systems are undergoing profound changes. The Energy Administration is bound to become more complex. Various "grey rhinoceros" and "black swan" events that threaten energy security occur from time to time, prompting profound changes in the international energy landscape. We will ensure the security of energy supply in an all-round way. To ensure the security of energy supply, we should not only improve the supply system of different types of energy, but also achieve multi-channel energy supply in space. Driven by the strategic goal of carbon peaking and carbon neutralization, China is accelerating the pace of replacing fossil energy with non fossil energy. Fossil energy has the characteristics of non renewable, high pollution and strong stability, while non fossil energy has the characteristics of renewable, low pollution, intermittent and volatility. In the future, China needs to gradually get rid of the dependence on fossil energy dominated by coal, develop strengths and circumvent weaknesses of fossil energy and non fossil energy, complement each other's strengths, adjust surplus and deficit, enrich the supply of different types of energy, and achieve green, low-carbon, safe and efficient energy supply. In the field of international energy trade, we should steadily expand connectivity with countries that have already engaged in energy trade, actively expand energy trade cooperation with more countries and regions, open energy supply channels, expand the geographical scope of energy supply, form a diversified, efficient and high-quality energy trade network, and "strengthen", "extend" the energy industry chain supply chain system. We will increase energy consumption security in a wide range of areas. The safety of energy consumption should be achieved from the aspects of energy conservation, efficient utilization and energy security management. On the one hand, in the process of implementing the dual control of the total amount and intensity of energy consumption, we should change the extensive energy consumption mode and promote the intensive use of energy. When deepening the market-oriented reform of energy prices, we should pay attention to stabilizing energy prices, prevent their abnormal fluctuations from causing instability in energy consumption, enhance consumers' rational expectations of energy commodity consumption, increase the universality of energy consumption, and ensure that consumers of different income levels can continue to consume energy. On the other hand, correct energy management can not only effectively save energy and improve energy utilization efficiency, but also reduce the negative externalities of energy consumption on the ecological environment. While the whole society is vigorously promoting energy conservation and efficient use, we should conduct publicity and education on the correct management of energy for the people, guide consumers to form the correct use methods and safety management habits of energy, and prevent incorrect energy consumption and management methods from harming social facilities, the ecological environment, and the safety of people's lives and property. Carry out energy technology innovation in multiple dimensions. Continuous energy technology innovation is an important magic weapon to ensure energy security.
