Inc
There is a high degree of sensitivity amongst organizations today to ensure that they do not add to
environmental abuse. In fact, it is no longer an exception to see customers specifying that their vendors
qualify for essential environmental standards.
Increasingly, vendors are running the risk of getting disqualified in the sales process unless their products
and services comply with international Green IT standards.
Is this talk about Green IT merely a fad?
Consider this!!!
The Servers that are running in Organizations consume power, air conditioning and generate heat that
adds to carbon emissions.
Take a scenario as below
If an inefficient server consumes 300 watts of power, that’s 2.62 megawatt hours/server/year
(300*24*365). Taking our calculations a little forward and translating electricity consumption into CO2
emissions. (Carbon dioxide "is the most prevalent greenhouse gas from the production of electricity.") It is
equivalent to 1.755 tons of CO2, which is equivalent to CO2 emission resulting from driving a sedan for
over 9500 kms.

The same calculations for 4 Servers will make it about 10.48 MWH/Year and CO2 emissions equivalent to a
CO2 emission whilst driving whopping 38000 kms.
An energy efficient server might bring down the CO2@ emission and green house gas effect by over 40%
SaaS
Besides Energy efficient servers, there are other ways of contributing to a Green IT revolutions. A
significant positive trend in the direction of Green IT is embracing the SaaS Model. The Software as a
Service (SaaS) delivery model offers a distinct approach carbon dioxide emission reductions.
Economies of scale realized from centralized processing and a shared services model automatically reduce
the number of decentralized servers thereby contributing to a smaller carbon footprint. Instead of
hundreds of thousands of customers individually operating their own servers and the power hungry
facilities to support those servers, the SaaS multi-tenant model centralizes data center operations to use
less equipment and a small fraction of the supporting facility costs.
Not only is it contributing to the Green IT revolution but it helps save costs by way of servers and
accompanied maintenance/upkeep expenditure.
Many businesses are now finding that switching to a Software-as-a-Service (SaaS) solution not only solves
this problem, but also offers many environmental benefits. In a time when "going green" is high on many
companies' priority lists, SaaS provides a great way to improve business processes on both fronts.
SaaS is Green!
When companies use SaaS applications, the vendor's central data center already provides the computing
resources to run the application. Customers do not need to consume critical resources to generate the
power for their own host machine. Further, the redundant backup power, HVAC systems, etc. are also
handled by the vendor data center and not the customer, which positively impacts the customer's bottom
line -- a very important benefit in a down economy.
Shared Resources such as in SaaS go a long way in optimal usage of infrastructure and not only preserve
the environment but save costs.
Green Data Center
A green data center is one which maximizes energy efficiency and minimizes environmental impact. All of
us need to make a difference in bringing in reforms and rethinking ways of optimizing equipment rather
than purchasing newer equipment. If scaling up is inevitable, it is important to consider energy-efficient
computing products.
