“Green IT” — the idea that IT organizations can and should implement practices and build environment friendly infrastructure.
IT organizations are increasing the attention to green IT has resulted from a number of factors, including:
- Rising energy costs over the past 5 years
- Increased awareness on global warming and “energy citizenship”
- Increased legislation surrounding energy efficiency, toxic materials, and greenhouse gases (GHG) in the United States, European Union, and China
As IT organizations are facing enormous pressure to cut costs and eliminate waste, the executives are now implementing the following areas to promote green practices:
- Data Center
o Eliminate energy leaks
o Use innovative and more efficient cooling methods
o Replace high-density servers with virtual servers
o Use alternative storage tactics
o Reconfigure data center floor layouts
o Explore alternative energy sources
- End-User Computing
o Alter purchasing practices for IT assets
o Encourage adoption of energy-saving settings on computers
o Practice proper disposal and recycling practices of IT assets
Green IT practices can lead to the following benefits:
- Reduced carbon and other GHG emissions
- Increased cooling efficiency in the data center
- Reduced energy costs
I hope that the brief examines the drivers of green IT initiatives and provides case examples of how companies have made IT more environment friendly.
