China leads the world in clean energy transition

China is leading the transition to clean energy sources thanks to a series of technological breakthroughs, with wind and solar power growing strongly.

As of the end of June, China's installed solar power capacity was 470 million kW, ranking first in the world for the eighth consecutive year, and its installed wind power capacity was 389 million kW, ranking first in the world for the 13th consecutive year, according to data from the National Energy Administration of China (NEA). The country is accelerating the upgrade of wind and solar power to achieve higher quality development, CGTN reported on September 6.

The wind energy sector has continuously had important technological breakthroughs such as the invention of super-long blades, helping China surpass other countries in terms of scale and technology of building floating wind power platforms, according to Li Chuangjun, director of the renewable energy and new energy department of the NEA.

The world's first 16 MW offshore wind turbine was installed off the coast of Fujian province in eastern China, connected to the grid and started generating power in July. It has a single-unit generating capacity larger than any turbine in operation in the world.

Wind power clusters are springing up across China, from Hainan Island in the south to the traditionally coal-producing province of Shanxi in the north. At a pilot wind farm in Tongyu County, Jilin Province in northeastern China, wind turbine blades with a diameter of 195 meters are in full operation. The blades are made from carbon fiber, which is lighter and stronger than traditional materials.

According to Yang Xudong, an official with China's Ministry of Industry and Information Technology (MIIT), the country's solar power industry is making rapid progress in technological innovation, and advanced products are also being applied more widely.

Cell technology plays a key role in the advancement of solar power. Recently, a solar cell module from Tongwei Solar (Chengdu) achieved a record-high module efficiency, certified by TUV Rheinland, a leading testing and certification service provider in Germany. Compared with traditional modules, the new module has better resistance to high temperatures and can generate electricity from both sides, which increases efficiency and reduces electricity generation costs, according to Meng Xiajie, deputy director of Tongwei Solar's advanced technology department.

The strong competitiveness has helped Chinese wind and solar companies expand their presence in the international market. According to the NEA, Chinese-made solar modules, wind turbines, gearboxes and other key components accounted for 70% of the global market share last year. Data from the National Bureau of Statistics of China showed that in the first half of this year, the country’s solar panel and wind turbine output increased by 54.5% and 48.1%, respectively.

China aims to increase its total installed capacity of solar and wind power to more than 1.2 billion kW by 2030 as it accelerates its transition to a cleaner energy system. The country plans to promote large-scale, high-quality solar and wind power generation between 2021 and 2025.
