     Energy is an important material basis for the survival and development of human society. It is vital to the prosperity and development of the country, the improvement of people's lives, and the long-term stability of society. The relationship between energy and economy and the economic issues of energy development have always been important contents that need to be paid attention to in the development of the national economy. The 19th National Congress of the Communist Party of China pointed out that socialism with Chinese characteristics has entered a new era, and my country's economy has transformed from a stage of rapid growth to a stage of high-quality development. As an important part of the national economy, energy must not only achieve its own high-quality development, but also must further play the role of energy in promoting high-quality economic development. This requires the guidance of the concept of energy development in the new era.
