As one of the three critical battles that are important for the building of a moderately prosperous society in all respects, fighting pollution requires an overall improvement in the quality of the environment. 

As China pivots to renewable energy to reduce its greenhouse emissions and fight pollution, hydropower continues to be the foundation of its renewable energy industry. According to the National Energy Administration, at the end of 2018, China's hydropower installed capacity was about 350 million kilowatts, and its annual power generation was about 1.2 trillion kilowatt hours, both ranking first in the world.

Developing hydropower is essential for China.  As hydropower stations are a source of clean, low-carbon, safe, efficient and renewable energy. Exploiting hydropower doesn't consume water and barely emits any greenhouse gases. 

As hydropower is increasingly marketized, it delivers greater economic, social and environmental value. It has also embarked upon a sound, sustainable development path within existing policies. 

China's hydropower enterprises have also been participating in cooperative projects around the globe. From the Belt and Road Initiative to China-Africa cooperation, China has been helping other countries to build their local hydropower plants. 

The major advantage of China's hydropower enterprises is their capability to offer comprehensive services that cover the whole industry chain – from planning, research, survey and design, to investment, construction, operational maintenance and skills-training. 

According to the China Power News Network, the country's hydropower enterprises are operating in more than 140 countries and regions, accounting for more than 70 percent of overseas hydropower construction. It is said that hydropower has become China's “beautiful business card” in world markets.
