At the just-concluded leaders’ climate summit, China made it clear that the key to green development is “green and low-carbon development of energy.” The carbon emission of photovoltaic power generation is one-tenth to one-twentieth that of fossil energy power generation. It is a true low-carbon energy source, but photovoltaic power generation currently only accounts for 3.5% of my country’s power generation. Photovoltaics will gradually become one of China’s important power sources in the future, providing a powerful engine for achieving “carbon peak” and “carbon neutrality”.
Dalat Banner in Inner Mongolia, the satellite discovered such a change. In the past three years, large squares have appeared in the Kubuqi Desert. After confirmation, this is a row of photovoltaic panels. This horse pattern alone is composed of nearly 200,000 photovoltaic panels. At present, the number of the entire area exceeds 3 million, making it the country’s largest desert centralized photovoltaic power generation base. Moreover, the area will be expanded. Once the three-phase project to be launched is completed, the annual power generation capacity of the entire base can reach 4 billion kilowatt-hours, which is equivalent to the electricity demand of the whole society for a year in an economically strong county.
Thousands of miles away in Datong, Shanxi, the former coal mining subsidence area has also been transformed into a photovoltaic base.
In Huainan, Anhui and Jiangyan, Jiangsu, photovoltaic panels built locally provide a good sun-shading effect for fish farming, realizing “fishing and light complementation”.
When looking at the whole country, the Aerospace Institute of Chinese Academy of Sciences used satellite remote sensing images to accurately extract the distribution of photovoltaic bases for us. Each bright spot on the map represents a concentrated photovoltaic power generation area. As of 2019, there are more than 2,600 such areas. This has led to rapid growth in the installed capacity of photovoltaic power generation in my country.
In 2011, China’s installed capacity was only 60% of Japan and the United States, and 6% of the EU’s. Since 2013, the country has increased energy conservation and emission reduction efforts, and the photovoltaic industry has developed rapidly. By 2017, China’s installed capacity will exceed the total of the European Union.
The photovoltaic industry chain is also continuously optimized and upgraded. Among the four major links of photovoltaic panel production, China’s output accounts for the global proportion, with the lowest reaching nearly 70%, and the highest even approaching 100%. In terms of the number of original patent applications, China surpassed Japan in 2013 to become the largest patent application country.
With the advantages of technology and output, the cost of photovoltaic power generation has fallen by more than 90% in the past ten years. Now in many areas of western China, the price of photovoltaic power is already lower than that of thermal power, which has laid a good foundation for the sustainable development of photovoltaics.
More than a dozen provinces in my country that have issued energy plans for the 14th Five-Year Plan have all made it clear that they will greatly increase the scale of photovoltaics. Among them, the installed capacity of Zhejiang, Jiangsu and other places will increase by more than half by 2025. According to the forecast of the Energy Research Institute of the National Development and Reform Commission and other institutions, by 2050, nearly 40% of China’s electricity consumption will come from photovoltaics. With the continuous development of clean energy such as photovoltaics, China will become more stable on the road to achieve “carbon peak” and “carbon neutrality”.
