Green - Energy Harvesting and I.Eswari 1 Assistant professor Department of , Syed ammal arts & science college, [email protected] S.Najiya Mahjabin2 Department of MCA, Mohamed Sathak Engineering College, [email protected] ------Abstract------Nowadays computer penetration is increasing globally at an amazing rate; hence the energy consumption is also growing rapidly which in turn affect the environment. So holistic approaches are necessary to reduce energy consumption. This paper focus on awareness to the computer users with regards to green computing. It is considered as a major contributing factor to green environment. The goal of Green computing is to maximize the usage of computing resources efficiently with less energy consumption and reduce usage of hazardous materials from which affect the environment. It also focuses on recyclability of products when they are produced with less hazardous materials and consume less energy during their life time. Here we tried to explore the current trends and challenges of Green computing and also what will be the future trends in Green Computing.

 Different wall papers consumes lot Increases of energy so instead of setting Electronic Item Purchases different wall Papers, set blackle as a home page. Blackle is a website powered by Google customsearch.whose screen is black Increases and fonts are graycolor.This arrangement consume less energy.

E-waste  To make the computer, environment friendly sleep and hibernate mode can be used. Both modes are Increases activated by manually or level.

Hazardous material : When a computer is inactive for sometime then the system automatically switches to lower power state. This state Increases preserve energy by cutting power, display hard drive and when pressing any key from keyboard, sleep Risk of Human mode deactivate and system takes back health problems. to its previous state .This mode mainly conserves battery power in laptop computers. E-waste contains a combination of Hibernate mode: reusable raw materials as well as toxic This mode available on materials [1]. Today much of the e-waste windows and and it was designed ends up in landfills. The toxic chemicals for laptops and may not be available for found in e-waste often leach into the ground or may be released into the air all PC’s. When this mode is activated, first data moves to hard disk of the which in turn affect the environment. system and then system is completely The most dangerous materials used in switched off. When the system is turn consumer electronics are, on, all files and documents appear as it i) Lead- which can be found in circuit is. In this method battery power can be board and CRT monitor. It is particularly dangerous to the environment as well as save a lot when start up the PC’s than sleep mode. it can cause permanent damage to the brain and nervous systems. ii)Cadmium- as toxic ,it is used in IV.

DVD and cell phones are commonly referred to as electronic waste.
