  • 12. In 1992, the U.S. Environmental Protection Agency launched Energy Star, a voluntary labeling program which is designed to promote and recognize energy- efficiency in monitors, climate control equipment, and other technologies. The term "green computing" may be created immediately after the Energy Star program began. The revised Energy Star Specifications of 2007 place stringent requirements to attain energy star ratings. In 2012, American household and businesses saved $24 Billion on utility bills Prevented greenhouse gas emission equivalent to that of 41 million vehicles. History of Green Computing
  • 13. Energy Conservation • Buy "Energy Star" labeled monitors, desktops, laptops, and printers • Turn off computers and peripherals when not in use • Put monitor in sleep mode or turn it off instead of using a screensaver • Activate the power management feature on your computer system • Reuse, Refurbish, or E-cycle used equipment
  • 14. Green Manufacturing • Bamboo is becoming increasingly popular for making casings for computers and peripherals • Use of recyclable plastics instead of non-recyclable plastics • Use of eco-friendly and non-toxic flame retardant compounds • Inventory Management: Process of reducing the quality of both, hazardous material and raw material • Volume Reduction: Removing of hazardous portion of waste from non hazardous portion
