Green Computing

GreenComputing is one of the recent trends that is growing inIT sector. Now each company are following the green principles before the design of their systems. Green computing helps in reducing the pollution and destruction of environment.The basic principles are followed here are green disposal, green design and green manufacturing, which are achieved through  ways like power management, green data center.
Green Computing systems take into account the so-called triple bottom line of people, planet, and profit.These focuses are green chemistry; reduction of the use of hazardous materials such as lead at the manufacturing and recycling stages, maximized energy efficiency during the product's lifetime, and recyclability or biodegradability of both a defunct product and of any factory waste.

ROADS TO GREEN COMPUTING
i) Green design
      Designing energy-efficient and environmentally sound components, computers, servers, cooling equipment, and data centers.
ii) Green manufacturing
       Manufacturing electronic components, computers, and other associated subsystems with minimal impact on the environment.
iii) Green use
      Reducing the energy consumption of computers and other information systems as well as using them in an environmentally sound manner.
iv) Green disposal
     Refurbishing and reusing old computers and properly recycling unwanted computers and other electronic equipment.

EMBODIED ENERGY
Embodied energy refers to the quantity of energy required to manufacture, and product, material or service. When considering the energy/emissions impact of IT equipment, the embodied energy of each element must be considered as well as the operational energy consumption for that equipment. Embodied energy is significant.
