Going Green Through Gmail

Cloud computing with Gmail can definitely save you money, but it also can save energy.  Results from the Carbon Disclosure Project show, “that by 2020, large U.S. companies that use cloud computing can achieve annual energy savings of $12.3 billion and annual carbon reductions equivalent to 200 million barrels of oil – enough to power 5.7 million cars for one year.”

Due to the movement of ‘going green’ and hard-working efforts to increase sustainability, Google decided to compare Gmail to locally hosted email servers in hopes to show how energy efficient cloud-based email really is. Here is an illustration of an inefficient use of email servers used by small companies in comparison to an efficient use of cloud-based email:

Google then tabulated the results, “switching to Gmail can be almost 80 times more energy efficient (PDF) than running in-house email. This is because cloud-based services are typically housed in highly efficient data centers that operate at higher server utilization rates and use hardware and software that’s built specifically for the services they provide—conditions that small businesses are rarely able to create on their own.”

With the above calculation it’s safe to say Google continues to act as the ringleader not only in a technological perspective, but now serving to help sustain our environment, one energy molecule at a time.
