4. History
 One of the first manifestations of the green computing
movement was the launch of the Energy Star program way back
in 1992.
 Energy Star served as a kind of voluntary label awarded to
computing products that succeeded in minimizing use of energy
while maximizing efficiency.

6. Real Reported Issues
 Servers and desktop PC s remain fully powered on nights and
weekends.
 Carbon dioxide emissions generated by cooling.
 Amount of electricity needed power and cool the data center
makes it one of the costliest aspects of an IT department.
 Facilities issues
Inefficient and expensive cooling methods
 Hardware issues
Energy-intense high-density servers
