It is reported that energy consumption is the biggest cost in the later operation of data centers, accounting for more than 50%. Reducing the energy consumption efficiency value (PUE) has always been the focus of the relevant departments in the industry.

The Guiding Opinions on Strengthening Energy Saving and Emission Reduction in Information and Communication Industry during the Thirteenth Five-Year Plan issued by the Ministry of Industry and Information Technology in April, 20 17 pointed out that the energy consumption efficiency (PUE) of newly built large data centers during the Twelfth Five-Year Plan period should be generally lower than1.5; By 2020, the energy efficiency (PUE) value of new large and super-large data centers must be below 1.4.

In March last year, the Ministry of Industry and Information Technology issued the "Guidelines for the Application and Development of National Data Centers" for the first time, saying that the average PUE (average power utilization efficiency) of national super-large data centers is 1.50, and that of large data centers is 1.69. According to the 13th Five-Year Plan, by 2020, the PUE value of new large-scale cloud computing data centers will not be higher than 1.4.

Today, the three departments jointly put forward clear guidance on building a green data center. In this context, how data center operators use new technologies and new structures to reduce energy consumption and realize the green development of data centers will become the focus of the industry. At the same time, under the general trend of energy saving and consumption reduction, it will also bring more market opportunities.
