Green data centers, for less energy consumption
Until a decade ago, companies hosted servers on their own premises, while the vast majority of individuals kept their digital data on their microcomputer at the local level. But today, professionals and individuals can take advantage of data centers to store their digital data safely and outside their own offices. A data center is a physical space – a single room or an entire building – that houses a large number of servers. Many data centers can now accommodate thousands of servers. It is estimated that data centers will be able to store 4 times as much digital data by 2021. This strong development of data centers is driven in particular by Cloud Computing. Cloud Computing is a recent digital practice that allows access to digital data stored on remote servers via the Internet, from wherever you are: at home, at work, on holiday…
Data Centers: how to reduce their impact on ecology?
According to statistics, while digital in general consumed about 10% of the world’s electricity production in 2015, data centers used 18%. In France, data center electricity consumption was 3 TWh, which is equivalent to more than the electricity consumption of the city of Lyon. Because of the joule effect – the dissipation of electricity in the form of heat – air conditioning accounts for nearly half of a data center’s electricity consumption. In order to reduce their electricity consumption and also reduce their environmental impact, some data centers prefer free cooling, i.e. natural cooling based on fresh outside air. Facebook, for example, has chosen to set up one of these data centers in Sweden, specifically in Luleå where the average annual temperature is 1.4°C. It is also possible to recover the heat produced by recovering it for district heating. In France, a public swimming pool in Paris, a student residence in Grenoble and the Val d’Europe business district already use this heating system.
In addition to data centers, terminals (computers, tablets, smartphones, etc.) and the Internet are also very energy-intensive. In 2015, it was found that terminals were twice as energy intensive as data centers. As far as the network was concerned, 4G consumed up to 23 times more than WiFi. To reduce energy consumption related to terminals and networks, the solution lies in individual awareness and responsible behaviour on the part of everyone.
