Google revealing how its products helping in green IT, today posted that their study about how Google Apps as a whole stacks up against the standard model of locally hosted services -- show that a typical organization can achieve energy savings of about 65-85% by migrating to Google Apps.
Last year, company made same revelation that its "Gmail is up to 80 times more energy-efficient than running traditional in-house email."
"A typical organization has a lot more servers than it needs--for backup, failures and spikes in demand for computing. Cloud-based service providers like Google aggregate demand across thousands of people, substantially increasing how much servers are utilized. The cloud can do the same work much more efficiently than locally hosted servers. It's all about reducing energy use for servers and server cooling."
Lower energy use results in less carbon pollution and more energy saved for organizations. That's what happened at the U.S. General Services Administration (GSA), which recently switched its approximately 17,000 users to Google Apps for Government.
"We found that the GSA was able to reduce server energy consumption by nearly 90% and carbon emissions by 85%. That means the GSA will save an estimated $285,000 annually on energy costs alone, a 93% cost reduction," posted Urs Hoelzle, svp for Technical Infrastructure.
How is the cloud so energy efficient? Here's how it works:

In other Google energy news, Google Sydney today posted that the two Mitsubitshi i-MiEVs electric cars today are used and 'booked out' for more than 80% of any given week.
"Over the last year and a half, the cars have travelled a combined total of about 36,000km, and they are completely powered by accredited GreenPower," posted Sam Thorogood, Software Engineer, Google Australia.
Google achieved this by giving 'points' to staff who commuted to work in a sustainable fashion, allowing them to be cashed in for business or personal use of the cars. Google engineers have use of what's known as "20% time", where they can devote one-fifth of their working day or week to a Google-related project of their choosing.
"Google Green Credits - or "GoCred" - is built entirely using Google products and technologies that are available to developers around the world, such as App Engine, mapreduce and the Google Chart API," Sam adds.
