The document discusses the history and goals of the ENERGY STAR program, which was launched in 1992 by the EPA to identify and promote energy efficient products. It aims to help consumers and businesses save money and protect the environment by adopting efficient products and practices. The ENERGY STAR label identifies top-performing, cost-effective products, homes, and buildings. The document also discusses green PCs and how organizations are focusing on deploying efficient computing systems and PCs that generate less heat and consume less energy through various measures like reducing brightness, unplugging computers when not in use, using laptops instead of desktops, and purchasing Energy Star certified models.

Greening CHAPTER 9
• The concept of green IT emerged in 1992 when the U.S. Environmental Protection Agency launched Energy Star, a voluntary labeling program identifies products that offer superior energy efficiency. • Organizations and consumers that use Energy Star products save money and reduce
ENERGY STAR  ENERGY STAR is the government-backed symbol for energy efficiency.  It was introduced as a volunteer labeling program to identify and promote energy-efficient products.  ENERGY STAR products, which can be identified by the label pictured above, use less energy and help you save money on your electric bill.
Its goal is to help consumers, businesses, and industry save money and protect the environment through the adoption of energy-efficient products and practices. The ENERGY STAR label identifies top-performing, cost-effective products, homes, and buildings. ENERGY STAR
Green PCs
Green Personal Computer • A green PC is also known as a green computer. • A green personal computer (green PC) is a computer designed to save energy. • A green PC is built from environmental friendly materials and features low power consumption and computer power management (CPM) capabilities. Green PCs usually generate less heat than their predecessors.
• Deployment of efficient computing systems and green PCs has become a major focus of many organizations. • Companies and businesses are keen to reduce their energy consumption and carbon footprint. • This has resulted in increased public awareness and ongoing efforts to reduce energy use. • Green PCs support sleep modes in which the PC powers down all unnecessary components when it is inactive because it is wasting the electricity. • As it generate heat and require additional cooling, which add to the total power consumption and cost. Green Personal Computer
Reduce PC energy consumption by adopting several measures: • Reduce computer monitor’s brightness: Most monitors have a built-in sensor that adjusts the screen’s brightness according to the amount of light in the room. We can also manually adjust our PC’s brightness to further reduce its power consumption. • Unplug computer when it’s not in use: Many people leave their computers on all day, even when they’re not using them, to save time powering up. However, this practice wastes a lot of energy. If we are not going to use the computer for a while, it’s best to shut it down and unplug it. That’s because a plugged-in computer (even when it’s switched off) still consumes standby power. • Option for laptop instead of desktop computer: Use a laptop instead of a desktop since laptops are designed to be more energy-efficient than desktops. • Keep laptop plugged in only when it is charging: We leave the laptops plugged in for hours, while they’re charging. The bad news is that overcharging causes the battery to deteriorate over time. When left plugged in, the charger still consumes power, even if it’s not connected to the computer. To save energy, unplug the laptop charger once we are done charging.
• Detach external devices from your PC when you’re not using them: Any external devices (e.g., printer, scanner, or webcam) connected to your PC continues to draw power even when they’re not in use. So when you’re not using them, make sure to disconnect these external devices from your PC. • Use a smart strip, especially for computers you cannot turn off: A smart strip automatically shuts down appliances when they go into standby mode. By connecting your computer and external devices to a smart strip, you won’t have to unplug your equipment when they’re not in use. • Pick an Energy Star-Certified PC: When buying a new PC, look for an Energy Star-certified model. Products that have the Energy Star symbol are guaranteed to deliver both quality performance and energy savings. The number of stars a product has indicates how energy-efficient it is.
 Building and certifying a green data centre or other facility can be expensive upfront but long-term cost savings can be realized on operations and maintenance.  Another advantage is the fact that green facilities offer employees a healthy, comfortable work environment.  Green facilities also enhance relations with local communities The following are examples of some of the technologies and strategies used in green a) Minimized Building Footprints. b) Low-emission Building Materials, Carpets And Paints. c) Sustainable Landscaping . d) Waste Recycling. e) Catalytic Converters On Backup Generators. f) Alternative Energy, Such As Photovoltaic Technology, Heat Pumps And Evaporative Cooling Technology And Hybrid Or Electric Vehicles.
