China's National Energy Administration reported on Tuesday that the country's installed solar capacity exceeded coal capacity for the first time. ^[1] Chinese state media reported on Tuesday that solar capacity surpassed coal capacity in July, becoming the primary source of installed electricity generation capacity in China. ^[2] Digital infrastructure is described as the backbone of the digital era, functioning similarly to water, electricity, and roads to enable effective computing and data transmission. ^[3] At the end of July, China's installed solar capacity reached 1.286 million megawatts. ^[4] China has committed to reaching its peak carbon emissions by 2030 and achieving carbon neutrality by 2060. ^[5] China had 1,288 gigawatts of solar capacity by the end of July, compared to 1,285 gigawatts of coal capacity, according to energy administration figures and state media. ^[6] Solar energy generation remains significantly lower than coal generation because solar power cannot produce electricity when the sun is not shining. ^[7] Wind and solar energy combined represented 24.6% of China's energy mix in the first half of the year, while coal accounted for 49.7%. ^[8] The author states that digital infrastructure allows for effective computing power, fast data transmission, and connected services. ^[9] The article introduces a specific discussion regarding the three invisible foundations that support China's digital infrastructure. ^[10]
