Is green computing good for business?
As more computing powers are required more electricity is needed.
The table below shows the annual cost of electricity for data center servers Year 2000 Year 2007
US $1.3 billion $2.7 billion
World Wide $ 3.2 billion $ 7.2 billion

Gartner group consultants believe that energy bills, which traditionally account for 10 percent of information technology budgets, could soon account for more than 50 percent.
The heat generated from computer rooms is causing equipment to fail. Companies spend as much money to cool the rooms as they spend to power it.
Some big companies are facing their power consumption issues looking into environment and saving money. Google, Microsoft, and HSBC are all building data centers that will take advantage of hydroelectric power.
For example one Microsoft data center deploys sensors that measure nearly all power consumption, recycles water used in cooling, and use internally-developed power management software.
PCs typically stay on more than twice the amount of time they are actually being used each day. One reports claims a 10,000 PCs will cost $165,000 annually in electricity bills if these machines are left on all night. It is believe that about $1.7 billion is wasted each year.
Few companies developed PC power management software that locks power settings and automatically powers PCs up right before employees arrive at work. For example one school cut the time its PCs were on from 21 hours to 10.3 hours daily, another firm saved $320,000 annually by turning off its 20,000 PCs when they are inactive at night.
