Baidu building with ice storage technology peak 'cut' of the electricity saving 4 million degrees every year

Recently, baidu released '2017 - 2018 baidu corporate social responsibility report, the report in the past two years, baidu in fulfilling social responsibility aspects of the practice and thinking, baidu with leading technology in the aspect of energy conservation and environmental protection effect, is worthy of reference for the industry. Report, baidu has been in self-built buildings, green travel, building a green data center and so on to realize substantially, energy saving and emission reduction in 2018 with the introduction of clean energy, only had reached 7 annual CO2 emissions. 80000. Baidu is data center green pioneer and leader in China, through the electrical system break through the traditional architecture, the deployment of the first batch of domestic built-in lithium battery rack server, the introduction of clean energy, improve the efficiency of power supply, reduce carbon emissions.

, energy saving and emission reduction is not only the urgent task of traditional industries, to support the emerging industries such as artificial intelligence, cloud computing data center also face this problem. According to statistics, as an important infrastructure, high-tech industry data center of the world's electricity consumption accounts for the total power consumption of the world's 1. 1% ~ 1. 5%, produce a large amount of greenhouse gas emissions, to resources and the environment bring great challenge. At present, the data center energy efficiency ( 电力使用效率,PUE) Generally higher, and data centers in the United States there is still a large gap.

as the leader of the Chinese AI and cloud computing, and baidu in the field of data center has more than 400 patents of technology innovation at home and abroad, is China's data center green pioneer and leader. It is reported, baidu data center has been adhering to the concept of green data center, aiming at saving energy and reducing consumption, practice & other; Data center as a whole, energy saving starting from the source & throughout; From the software architecture, IT equipment and infrastructure, Electrical systems and the hvac system) A number of green energy-saving technology application innovation, and the AI technology is introduced into data center, intelligent decision-making, intelligent cooling, saving energy and reducing consumption substantially.

just released the '2017 - 2018 corporate social responsibility report shows that baidu baidu cloud computing data center single mode group 2018 annual average PUE reaches 1. In the domestic first 09. According to the Uptime Institute released the 2018 survey data center, the 2018 global data center PUE is 1. 58. Baidu in the data center energy efficiency performance far exceeds the international average. All four yangquan data center in September 2018, is expected to reduce the power consumption of 2 each year. 20 200 million degrees, reduce CO2 emissions. 30000 tons. In addition, baidu also introduce clean energy, 2016 - In 2018, the cumulative declare and signing of wind energy and other clean energy by 81 million degrees, 7 annual CO2 emission reduction. 80000 tons, the equivalent of 1. 67 million trees a year of CO2 uptake.

in addition to the data center to realize energy conservation and emissions reduction, baidu's self-built buildings and measure of enterprise energy conservation and environmental protection measures. It is understood that baidu self-built buildings in the ice storage technology. Each cooling season, through the power load trough the preparation of cold at night in the daytime power during the peak load in preparation for central air conditioning system cooling capacity and cooling, reduce the power peak load of power grid, which can effectively reduce power grid peak valley difference, realizes the power & other Peak cutting & throughout; , improve the load rate of power grid, and saving the enterprise's actual consumption spending. Through & other; Peak cutting & throughout; Baidu, electricity can save about 4 million degrees all year.

baidu also by building new wind system recover part of the amount of cold and heat, to achieve energy saving effect. Refrigeration season recovery of cold energy in a fresh air system, refrigeration power saving 1. 8 million degrees; The quantity of heat recovery fresh air system, heating season save heating with volume of 150000 cubic meters of natural gas; In addition, LED energy-saving lamps and lanterns is used in great quantities in the baidu space, compared to common fluorescent lamp, a year to save electricity is about 580000 degrees; Baidu solar collector heat transfer with a total area of 1178 square meters, all the year round to provide living hot water; Baidu has built rainwater collection pool three science park phase ii, rainwater reuse throughout the year around 2400 m.

as the world's largest Chinese search engine, AI leaders, baidu to & other; Use technology to make the complex world more simple & throughout; As the mission, the social responsibility as an important dimension of development. Through self-built buildings, green travel, energy conservation and environmental protection efforts and action on the level of the data center, baidu to leading technology to explore the way of improving energy efficiency, environmental protection, the green data center construction, build green building technology, experience, is worthy of reference for more business. In addition to the report, the baidu also increased the feedback on their CSR website platform, accept user for the advice of the corporate social responsibility, to improve and enrich the relevant practice.
