Zhang: Cloud computing High energy Consumption data center annual consumption of tens of billions

"Cloud computing" is very energy-intensive, Zhang said on the 2012 China-US Clean Energy Forum held in Nanhui New Town, Shanghai. Energy data from the China Unicom Data Center, which he holds, shows that the center consumes 9.9 billion-kilowatt times a year. With China's current coal efficiency, 920,000 tonnes of coal will be needed to provide enough power for China Unicom's data center to consume energy.

Zhang also said that, with China Unicom, the Chinese Telecom Data Center annual consumption of 11.2 Billion-kilowatt, the total annual consumption of 1.0295 million tons of coal.

2011, Zhang said China's electricity structure, the proportion of firepower generation still reached 83%, a total of 9.8 billion tons of coal burning.

According to NetEase financial understanding, in the communications industry, operators of the data center is a large power consumption. Globally, the total power consumption of ICT (information communication Marvell) accounts for about 8% of the total power consumption in the world, with data centers being the most power-hungry projects in ICT, which have reached close to Chicho each year.

According to a Greenpeace report, by 2020, the world's leading IT operators "cloud computing" (including data processing and telecommunications network) energy consumption of nearly 2,000,000,001,000 watts, more than Germany, France, Canada and Brazil and other 4 countries combined energy consumption.

The report says companies such as Apple, Google, Amazon and Facebook have been using the ever-increasing cloud, leading to massive construction of air-conditioned data centers full of servers. The facility, built by Facebook in Oregon State, will be run by power plants that rely on major fuels for coal, and Apple is building data-storage systems in North Carolina, which relies mostly on coal-fired energy. The data center will consume 1.963 Trillion-kilowatt of its power resources by 2020, more than the current amount of electricity consumed by France, Germany, Canada and Brazil.
