Through 28 years of practices, Yumen in Gansu province has transformed from a cradle of China's petroleum industry into a city of green energy.

The city has now built an industrial cluster combining wind, solar, water, and hydrogen storage resources worth about 100 billion yuan ($13.93 billion), becoming a model for the transformation of resource-based cities.

In 1997, Danish-made wind turbines were installed in Yumen, launching the development of new energy in western China. In 2007, a 200,000-kW wind power project was launched in the city, shifting the city's new energy industry into large-scale development. In 2009, construction on a national wind power base with a capacity of tens of millions of kilowatts also began.

At present, innovation driven has become the core for the green development of Yumen's new energy sector. At the Yumen Oilfield Renewable Energy Hydrogen Production Demonstration Project site, photovoltaic power is converted into high-purity hydrogen through electrolysis water technology, giving birth to a fully integrated green hydrogen industry chain.

As of the end of 2024, the installed capacity of Yumen electric power had reached 7.24 million kilowatts, with a cumulative power generation of 76 billion kilowatt-hours.
