The dawn of the laptop era presents new challenges to the computing research community. Performance is no longer the end all be all of computing research because a new, significant requirement has cropped up: reducing the power consumption and improving battery usage. The key restriction to mobility is the constant need to be near a power outlet to recharge the laptop battery. Thus, extending battery life without compromising performance is a pressing concern. A research named as "iGreen" was

... oposed to stimulate power consumption awareness and behavioral change among laptop users via interactive energy-usage feedback with college students as the initial target group. This project is part of iGreen the project with an objective to analyze the users' behavioral changes by examining their usage of laptops and their attitude towards the environmental issues for energy consumption. It also tries to find reasoning and provide a social feedback mechanism to improve the efficiency of energy consumption and reduce the waste of power. v
