Data centers are huge energy guzzlers mainly because…

With the fast growth of Internet and cloud services, the need for more and larger data centers is also increasing globally.

Data centers already consume significant amounts of electricity, and thus are responsible for significant amounts of CO2 emissions. Globally, about 600 million tons of CO2 emissions are contributed from data center operations alone, about 2% of total CO2 emissions.

Why do data centers require so much electricity? While part of the electricity is needed for operating the servers, a good portion – close to 50% in some cases – of the energy is used for cooling the servers.

Thus, data center cooling alone could be contributing to about 300 million tons of CO2 emissions worldwide – more than the annual emissions of about 90% countries in the world.

So, efficient methods that can halve the energy required to cool data center servers could save 150 million tons of CO2 emissions every year!
