This project is quite successful in Germany. In the past five years, local carbon dioxide emissions have been reduced by 38.1% and the average annual energy modernization rate is three times higher than the German average. ] The town of Bottrop, in the northwestern part of Germany, is not well-known to Germans, but the town of Ruhr, once relied on coal resources, is morphing into an urban laboratory, attracting businesses to experiment with Energy-saving innovation. This, at the other end of Eurasia, has aroused the interest of Chinese officials. At the end of May, Bernd Tischler, the mayor of Bottrop, who led locals onto the road to innovative cities in a restaurant in a Bottrop park restaurant, told The First Financial Times reporter: "Soon, Before I just met with your Minister of Environmental Protection, he was very interested in Bottrop's urban transformation.We also signed an intent cooperation agreement with Pingdingshan City, a coal mine in Henan Province, where both parties exchanged experiences of urban transformation, And promote the businesses of the two places to open markets to each other's cities. " Energy City Transformation Experiment Bottrop, a municipality in North Rhine-Westphalia, is located in the northwestern part of the Ruhr industrial area of ​​the state. With its rapid expansion of rich coal resources, the population has now risen to about 120,000. However, like other cities in the Ruhr area, it is difficult for Bottrop City to rely heavily on the development of coal resources. In the 1960s, cheap oil and gas were gradually becoming mainstream energy sources, and coal's position in energy was greatly weakened. At that time, the shallow coal mines in the Ruhr area were almost exhausted and suffered a serious "coal crisis", which in turn led to the relocation of the iron and steel enterprises and the Ruhr area into a "steel crisis." Tischler told this reporter that the substantial increase in local coal mining costs and the environmental problems caused by coal mining are all forcing the urban transformation. In the 1980s, the local embarked on the road to restructuring and the two last coal mines will be closed in 2018. "Innovation" will become the key word for the smooth transition of this energy-based city. Tischler, who became mayor of the city in 2009, led the citizens onto an innovative city that paved the way for a project called the "City of Innovation Ruhr." The project, coming from a group of about 70 companies in the Ruhr area, launched the "Future Urban Climate Competition" in early 2010. In November of that year, an independent jury chose Bottrop from 16 applications. Companies such as Siemens will provide technical and financial support for the city's transformation. The "City of Innovation Ruhr" project aims to rebuild the industrial zone with a planned operation of 10 years (to be completed by the end of 2020), which will halve its carbon dioxide emissions and improve the quality of life of its residents. Tischler proudly told the "First Financial Daily" reporter that the project was quite successful in Germany. Over the past five years, local carbon dioxide emissions have been reduced by 38.1% and the average annual energy modernization rate is three times higher than the German average. He believes that the next five years will be able to achieve 12% reduction in emissions, so as to achieve the goal of halving the ten-year period . Through this project, Bottrop is being built as a laboratory for business innovation. Many companies are now starting to apply their technology locally and using the city to demonstrate their innovative results.
