Image This paper shows that, compared to onsite IT systems, open source cloud computing (OSCC) saves an average of $1,035 and 0.64 tonnes of CO2 per person on setup, and $742 and 0.46 tonnes of CO2 per person each additional year, making it the greenest information technology option available to small and medium-size organizations today.

OSCC was found to have four key efficiencies with significant cost and green benefits.  Savings were estimated for a representative, cost-conscious, small to medium-size organization ….

Onsite Comparison

Internet packets now travel close to the speed of light of 300,000 kilometers a second, and the switching time at routers in between continues to trend toward zero.  Which means, since our planet is 40,075 kilometers round, that a packet could someday completely circle the earth a bit more than seven times in single second ….

Open Source

Open source software helps you reduce costs for both acquisition and support, enables you to provide more capability to your team and increase productivity, and supports ongoing development of a globally efficient asset that generates compounding value for you over time, while building the best possible IT solution ….

Efficiency Benefits

After carbon savings have been achieved by an efficiency, it would be helpful to know the overall retained net benefit.  In the case of retained green benefit of efficiency and productivity gains, one study has shown that an hour of work saved can translate to about an 80% saving in the associated greenhouse gas impact of that hour ….
