"Energy security is an overall and strategic issue that has a bearing on the country's economic and social development. It is vital to the country's prosperity and development, the improvement of people's lives, and the long-term stability of society." "We must, from the strategic perspective of national development and security, judge the hour and size up the situation, take advantage of the situation and find ways to adapt to the general energy trend." "Solving the core demand for oil and gas is an important task facing us. We need to intensify exploration and development, consolidate the domestic production base, and improve our self-protection ability." "The development of the coal industry should be transformed and upgraded, and take the road of green and low-carbon development. In this way, it will not exceed the limits of resources, energy and environment." "We should give more prominence to promoting the development of new and clean energy, and actively and orderly develop light energy, silicon energy, hydrogen energy and renewable energy." Energy is the foundation and driving force of human civilization and progress, and it has a bearing on the national economy, people's livelihood and national security. 100 meters underground, rolling "black gold" intelligent mining; The boundless sea, the giant platform built independently; In the vast desert, the photovoltaic "blue plate" releases clean energy... The vast number of energy enterprises keep in mind the general secretary's instructions, spare no effort to ensure the safe and reliable supply of energy, accelerate the transformation of clean and low-carbon energy, and promote the high-quality development of energy. "Rich coal, poor oil and little gas are the national conditions of China, and it is necessary to consolidate the foundation of domestic energy production". As the largest energy consuming country in the world, how to grasp the strategic bottom line of self-sufficiency in domestic production of important energy and effectively guarantee the national energy security is the primary issue facing China's energy development. He stressed: "rich coal, poor oil and little gas are the national conditions of China. We should consolidate the foundation of domestic energy production and ensure the safety of coal supply." power supply and heating are related to the overall situation of economic development and social stability, and are major issues related to people's livelihood. Entering the summer peak period, Hu Junfeng, general manager of Ruiguang Thermal Power Co., Ltd., tightened his strings: "not only power generation, but also the cooling supply of Wusu airport around us. We must ensure the stable operation of the unit and never fail to live up to the expectations of the general secretary." Ruiguang thermal power operates two 300 MW cogeneration units with an annual power generation capacity of 3 billion kwh. It not only needs to generate electricity and provide cooling, but also undertakes the heating task of 24 million square meters in Taiyuan and Jinzhong in the heating season. The coal and electricity supply is guaranteed. The speed and quality of coal feeding are very important. The northeast corner of the plant is the coal storage yard of Ruiguang thermal power. Before entering the coal storage yard, heavy trucks have to go through a special checkpoint: intelligent robots automatically sample and test, and upload key data such as coal calorific value in real time. Looking at the high "coal mountain" in the coal storage yard, Hu Junfeng was very confident: "the current coal storage can maintain operation for more than two weeks. We are also continuing to promote energy-saving transformation. The coal consumption has decreased from 332 grams per kilowatt hour to 285 grams. The same weight of coal can generate more 'light and heat'." Oil, known as the "blood of industry", is also an important strategic resource of the country.
