6. ABSTRACT
Green Computing is a recent trend towards designing, building, and
operating computer systems to be energy efficient. In the present scenario
green is all over the news like green jobs, green products, and green
programs. While programs such as Energy Star have been around since the
early 1990s, recent concerns regarding global climate change and the
energy crisis have led to renewed interest in Green Computing.
Green Computing deals with different green computing factor applied to
reduce environment hazards and deals with latest invention regarding green
computing to reduce the thermal power from the processor. Green
computing is essential for using computing resources efficiently. Typically,
technological systems or computing products that incorporate green
computing principles take into account of economic viability, social
responsibility, and environmental impact. A typical green computing
solution attempts to address some or all of these factors by implementing
environmentally friendly products in an efficient system. 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).The work habits of computer users and businesses can be modified
to minimize adverse impact on the global environment.
The present scenario in Green Computing is all about making good choices
that reduce the wear and tear that our computing practices have on the
planet. It represents a variety of ways to reduce your power consumption

7. by changing your practices, upgrading your system, buying green, and how
to dispose of old computer equipment in a way that is kind to the planet.
