Green computing is the environmentally responsible use of computers and related resources. Such practices include the implementation of energy-efficient central processing units (CPUs), servers and peripherals as well as reduced resource consumption and proper disposal of electronic waste (e-waste). Green IT is taking on a bigger role for many reasons, this book covers all areas including an increased awareness of environmental danger; concern about power bills; regulatory requirements; government procurement rules; and a sense that corporations should embrace social responsibility.But IT is still responsible for 2% of all carbon releases, and it's coming from many sources. Fast memory for instance is getting to be a surprisingly high energy consuming item.This is a great book as it highlights Green IT in a clear and compelling way and shows how, really, the business case for sustainability has been largely proven. This is a quality, believable business book that will help especially managerial staff understand this topic in biz terms most known to them.
