Companies looking for a green IT solution may want to investigate cloud computing, as it can offer more simple maintenance, faster updates and lower costs, as well as the ability to cut emissions and energy costs, according to TechTarget.

“Energy use is certainly an important consideration in the datacenter, and cloud solutions are more efficient than traditional systems,” said Eric Woods, research director at Pike Research Inc.

The news source said that between 2011 and 2020, ICT equipment and services emissions are expected to double from 2 percent to 4 percent of total emissions worldwide, so many are hoping that the cloud can help IT cut its greenhouse gas contributions.

TechTarget said a green cloud computing solution helps with more efficient provisioning, better business dynamics and multi-tenancy. With cloud computing, there can be shared infrastructures that will work in a more efficient way than autonomous ones. This should work to reduce energy costs and carbon emissions over the coming years.

The Carbon Disclosure Project said cloud computing could help cut 9.2 million tons of CO2 annually by 2020 in the United Kingdom, and carbon emissions equivalent to 200 million barrels of oil in the United States.
