Nitrogen energy conservation, compressed air energy conservation, old air compressor energy conservation replacement... Chongqing Pinghu Jinlong Precision Copper Pipe Co., Ltd., located in Wanzhou District, the hinterland of the Three Gorges Reservoir Area, has completed 27 major energy conservation projects in recent years, saving more than 13000 kilowatt hours of electricity per month and 32000 tons of water per year. Based on the total output in 2021, the company saved a total of 35.8248 million yuan, becoming an advanced model of green manufacturing for Wanzhou enterprises. In accordance with the requirements of building an important ecological barrier in the upper reaches of the Yangtze River, all districts and counties in the Three Gorges Reservoir Area in Northeast Chongqing have made every effort to promote ecological priority and green development around industrial ecology and ecological industrialization. The appearance of green water and green mountains and the value of Jinshan and Yinshan have been continuously improved, and a green development path has been blazed out. At the time of welcoming the 20th CPC National Congress, green industries on both sides of the Yangtze River are showing great vitality. Relying on Chongqing's big data intelligence strategy and the construction of "smart manufacturing center and smart city", Wanzhou has implemented green enabling technology transformation for key enterprises and industries in the region. There are more than 1000 digital economy enterprises in the region, and two enterprises have successfully created "national green factories". Wanzhou Economic Development Zone has also been approved as a national demonstration park for recycling transformation because of its achievements in promoting green and high-quality development of industrial economy. Sanba Wind Farm in Fengdu County, completed and put into operation in 2015, has an annual power generation of 97.11 million kWh, which is one of the largest wind farms in Chongqing. By 2021, the total installed capacity of Fengdu's wind power project has reached 350000 kilowatts, ranking first in the city, with an annual grid power of 650 million kilowatt hours. Compared with thermal power projects with the same power generation capacity, it can save 208000 tons of standard coal and reduce 525500 tons of carbon dioxide emissions annually. This summer, Chongqing has been sunny and hot. These green electricity from the mountain wind has brought a cool feeling to many families. "Last year, the energy consumption of Kaizhou's 10000 yuan GDP decreased by 5% year on year, and the energy consumption of 10000 yuan industrial added value decreased by 8%." Gao Yuqiao, deputy director of the Development and Reform Commission of Kaizhou District, introduced that Kaizhou aimed at energy saving economy and circular economy, and developed four green leading industries, namely energy and building materials, medicine and food, electronic information, and equipment manufacturing, by eliminating and closing 91 backward enterprises with excess capacity. Green transformation should not only focus on the long-term, but also adapt to local conditions. Like many districts and counties in the Three Gorges Reservoir Area, Fengjie County faced a large number of idle labor resources and industrial development bottlenecks for a long time after the relocation. In 2015, Fengjie seized the opportunity of the cascade transfer of coastal industries to build the eyewear industry. In seven years, it gathered 82 enterprises with a total output value of nearly 1.5 billion yuan, and also developed a supporting vocational education system including eyewear manufacturing and optometry. In Chongqing, where 98% of the total area is mountainous and hilly, Liangping District, the largest plain in the city, is a national key grain producing region. Liang Ping took the development of the prefabricated vegetable industry as a breakthrough to realize the leapfrog development of the food industry and a new engine for economic growth. He took the lead in proposing to build the "Prefabricated Vegetable City in Western China", which focuses on Sichuan cuisine. Currently, 30 prefabricated vegetable industry projects have been signed, with an agreement to attract 10 billion yuan and more than 50 enterprises. "Digital Smart Forest Town" is a new exploration of Yunyang County for the development of green and intelligent cities and towns. The town maximizes
