This document discusses green computing, which aims to reduce the environmental impact of computers and data centers. It seeks to do this through green use of reducing energy consumption, green disposal of electronic waste safely, and green design and manufacturing of sustainable hardware. While green computing can save money, it may also increase costs and lead to underpowered computers. However, initiatives like EFGCD are working to define standards to guide the industry toward a sustainable future.

4. History
 One of first manifestations of the green
computing movement was the launch of the
energy star program back in 1992

17. Pros:
 Saving energy and resources saves money.
 Reduce the risk existing in the laptops such
as chemical known to cause cancer , never
damage and immune reactions in humans

18. Cons:
 Green computing could actually be quite
costly.
 Some computers that are green may be
considerably underpowered
 Rapid technology chage.

19. Future:
 The Green Computing initiative , stewards
of the industry standard EFGCD(Eco-
Friendly Green Computing Definition)
