By: Vinay V.Kale Department of MCA Siddhant College of Engineering Slide 2: Outlines… What is 'Green Computing' ? Need of 'Green Computing' How to achieve 'Green Computing'? Simple way to achieve 'Green Computing' at home Conclusion Slide 3: What is 'Green Computing' ? Practice of using computing resources efficiently. The utmost requirement to protect environment and save energy along with operational expenses in today's increasingly competitive world. Slide 4: Need of 'Green Computing' ? Slide 5: Energy Use of PCs CPU uses 120 Watts. CRT uses 150 Watts. Electrical current to run the CPU, motherboard, memory. Running the fan and spinning the disk(s). Monitor & Printer. Slide 6: Chemical Elements Found in Computers and Components Elements in bulk:- lead, tin, copper, silicon, carbon, iron and aluminum. Elements in small amounts:- cadmium and mercury. List of examples of devices containing these elements are: Almost all electronics contain lead & tin (as solder) and copper (as wire & PCB tracks), though the use of lead-free solder is now spreading rapidly. Lead: solder, CRT monitors (Lead in glass), Lead-acid battery. Slide 7: Disposal Consider that the average computer lifespan is about 2 years (cell phones < 2 years). Between 1997 and 2004, it is estimated that 315 million computers became obsolete (and were discarded, donated, or recycled) 183 million computers were sold in 2004(674 million cell phones). Disposal of these devices constituted 20-50 million tons per year (about 5% of the total waste of the planet). This waste is called e-waste. Where are we going to put all of it? Slide 8: Land Fills The US and Europe export a lot of e-waste to Asian landfills (especially China even though China has outlawed the importing of e-waste). In addition, incineration of computer components leads to air pollution and airborne toxins. Slide 9: How to achieve 'Green Computing' ? By replacing petroleum-filled plastic with bio plastic (“plant based polymers”). Avoiding the discarding of computer not only helps to reduce e-waste but also saves energy and material needed to manufacture a new computer. Use of toxic materials like lead can be replaced by silver and copper making recycling of computers. By recycling computer parts separately with an option of reuse or resale. Slide 10: Simple way to achieve 'Green Computing' at home. Turn off your computer when not in use it will save energy up to net a 67% annual savings. Purchase flat-screen monitors—they use significantly less energy and are not as hard on your eyes as CRTs. Plan your computer-related activities so you can do them all at once, keeping the computer off at other times. Enable the standby/sleep mode and power management settings on your computer. Choose dark backgrounds for your screen display—bright coloured displays consumer more power. Slide 11: Projects On Green computing Power saving by link status Wi-Fi Scheduler Slide 12: conclusion “Green computing has introduced a range of equipment and technologies which help in limiting the impact on the environment”. “Green Computing opens a new window for the new industrialist for harvesting with E-waste material and scrap computers”. “Green Computing grows demand for network computing without putting such pressure on the environment”.
