Green computing aims to support environmental and social responsibility in addition to financial performance. It focuses on improving energy efficiency, promoting recyclability, and reducing hazardous materials. Existing programs like ENERGY STAR and EPEAT establish standards for energy efficiency and the life cycle of electronic products. A case study found that a government data center saved energy by restricting employee access at nights and weekends without compromising security or oversight through remote maintenance. However, e-cycling programs have high costs and only 50% of usable electronics are recycled, with 70-80% shipped overseas without proper disposal methods.
