The data center industry consumes an enormous amount of water, and Google is no exception. In a recent post, Google revealed how much water it uses each year, and the results are staggering.
The tech giant has always done that kept his water consumption a secret in its data centers. Subsequently, many speculations circulated on the web, creating debates about the environmental responsibility of data infrastructures. Today, the American giant has decided to break the silence to end the debate.
Google’s data centers use 15 billion liters of water per year
15 billion liters of water represent approx 4 billion liters of water. To give an idea of the scale, it is approx. 10 times the capacity of an American football stadium full of water.
Ben Townsend, head of water strategy at Google, explained that the company kept these figures secret the privacy of the data power in each Google data center.
It is important to note that you use this amount of water may affect local water resources. This affects all the more in regions where water is scarce or expensive. Data centers and the companies that operate them should therefore be aware of these impacts and seek more efficient and environmentally friendly cooling methods to reduce water consumption.
Why do data centers need so much water?
Water is mainly used to cool servers, as well as to drive the pumps and other plant equipment. This keeps the data center temperature within an acceptable range, so prevent servers from overheating and don’t go down.
this process requires a large amount of water, because it constantly evaporates and needs to be replaced. Moreover, water is used to clean the components data center, as dust and other particles can affect hardware performance.
Currently, water is the most used element for data center cooling systems. In fact, she is one excellent heat conductor. It is the most effective fluid for dissipating the heat generated by computer servers. Moreover, water is plentiful and cheap compared to other cooling methods such as refrigerants.
