Powerful Argument for Cutting IT Energy Consumption

View as: Print Mobile App Share:

Although technology is growing more and more energy efficient, more innovation is needed to offset the growing use of computers in countries such as India and China. The focus on innovation "has also sparked the redesign of technology and the revival of old ideas that have gained a new relevance to reduce resource use and cut greenhouse gas emissions," says 1E CEO Sumir Karayi. Better use of server capacity, optimizing cooling, more energy-efficient equipment, and reducing data and applications can reduce carbon dioxide emissions by 75 percent, according to Deutsche Telekom.

T-systems and Intel are researching energy-efficient data centers and focusing on reducing power usage effectiveness. "As IT becomes more dynamic with virtualization and cloud computing, a new dynamic data center infrastructure is emerging that is more closely integrated with the IT assets it supports, flexible in its deployment, and adaptable to rapidly changing operational conditions—like a green data factory," says Pike Research's Eric Woods.

The next step is to use intelligent software to manage energy consumption by the servers.
