With the deepening and widespread application of digital technology, the world has entered the era of digital economy, and the total amount of data in the society is exploding, and the demand for computing power is also expanding continuously. As the physical carrier of computing power development, data centers are facing many challenges while blossoming all over the world, the first and foremost of which is green, energy-saving and low-carbon.
Data show that the number of data center racks in China has increased from 1.244 million in 2016 to 3.15 million in 2019, a three-year increase of 154%, with the proportion of mega data centers increasing from 11.3% to 37.4%. Data center power consumption in 2030 is expected to be 5.1 times higher than that in 2020, which means that the construction and development of data centers will itself pose a huge energy consumption challenge.
In terms of the total energy consumption of domestic data centers in 2020, it has exceeded 200 billion kWh, which is about 10 days of the whole society's electricity consumption. If converted into standard coal combustion for power generation, it consumes 60 million tons of coal combustion and emits 160 million tons of CO2. It is undeniable that data centers have become a key area of concern for "carbon emission reduction".
Especially under the national carbon peak and carbon neutral target, promoting the decarbonization transition of the data center industry is important for China to achieve the "double carbon" target. In addition, how to make the data center, which is a major energy consumer, reduce the cost of electricity and achieve effective energy saving and emission reduction is not only related to industrial development, but also crucial to promoting sustainable social development, based on which, the construction of green data center is becoming a major trend.
Carbon peak and carbon neutral are hot terms in the past two years. In September 2020, China announced that it would strive to reach peak CO2 emissions by 2030, and strive to achieve carbon neutrality by 2060. In the context of the country's "dual carbon" strategy, data centers, as the digital substrate of the "new infrastructure", have been given more expectations.
As we all know, in the current era of explosive data growth, the processing capacity and storage capacity of data centers have grown exponentially, and the consumption of energy has also risen, and according to a study by Ariadne, the current cost of electricity has accounted for more than half of the overall operating expenses of data centers. Therefore, to achieve the goal of "double carbon", it is crucial to build a green data center.
In order to accelerate the construction of green and low-carbon data centers, a number of policies have been introduced at the national level to help them. With the accelerated progress of digital transformation and upgrading in various industries, there is an urgent need to promote reasonable layout, balanced supply and demand, green intensification and interconnection of data centers, build a new arithmetic network system integrating data centers, cloud computing and big data, promote the circulation and application of data elements, and realize green and high-quality development of data centers.
