We have done our analysis on power consumption of computer. We have stated different management policies for reduction in energy consumption. Energy Star (ES) programme of the United States promotes energy efficiency in electronics products that provides an exceptional productivity as compared to the old or traditional systems. Energy Star program has been adopted by many countries to make a move towards Clean and Green environment. ES labels can be easily found on electronic appliances at homes, offices, buildings and many other places. Depending upon the devices, using these policies can result between 30%- 90% of less power consumption. In our analysis, we got a reduction of 40% less power consumption in computers after implementing management policies. In this work, we are estimating power bill, and analyzing its economical feasibility along with that we are proposing a plan to reduce power consumption of academia and Institute. We have also discussed about management policies for disposal of e-waste.

Introduction Although computers play a pivotal role in life of human. Whereas, exponential growth of computers, Smartphone, laptop, and Personal Digital Assistant (PDA) used for personal or official purposes by individuals and organizations for a very long period of time almost over one decade has positive as well as negative effects on the environment. Benefits of these devices have helped us to store a huge amount of information though computer without even compromising our natural resources (e.g., paper). Along with positive ecological benefits, technology has made harmful footprint on the environment. Organizational green motivations behind green Information Technology (IT) policies are main guiding factor behind Green IT investments [1]. Energy Star (ES) programme of the United States promotes energy efficiency in electronics products that deliver better services than traditional equipment without the Energy Star label [2]. Along with manipulating FPGA resource, LVCMOS IO standard, Voltage Scaling, Frequency Scaling, Clock Gating, and Adaptive Voltage Scaling (AVS) are also energy efficient techniques that are in use of energy efficient design of ALU [3], Mobile Battery Charge Controller Sensor (MBCCS) [4-5], state-of-the-art VLSI designs in 40 and 65 nm processes [6].
