BusinessWeek has an interview with IT managers in India, Intel, and EMC.

India is facing a power shortage of 70,000 megawatt (MW). As a result, to maintain power supply, much of corporate India has had to rely on generators that run on diesel and cause pollution. And with the soaring crude price, Indian enterprises are faced with escalating energy bills.

Ravichandran said: "Although the desire to create a greener planet will drive some implementations, the primary driver for green IT adoption in Asia-Pacific is the cost savings provided by higher energy-efficiency."

Virtualization is discussed.

"Companies across segments in IT and IT-enabled services (ITES) in India have been early adopters of consolidation and virtualization," Sanjiv Kapur, senior vice president and head of Patni-BPO, told ZDNetAsia in an e-mail interview. Patni Computer Systems is an Indian company providing IT services. "At Patni, almost 50 percent of our data centers are virtualized," Kapur said.

A recent IDC India survey estimated that 22 percent of servers were virtualized in 2007, and projected this would increase to 45 percent by end-2008.

"The virtualization trend is fast catching up in India," Kapur said. "Most of the leading companies in India are proactively looking at server consolidation, virtualization as well as improved cabling architecture."

Today, Indian companies have an array of green computing alternatives to choose from, with large IT vendors including Intel, EMC, IBM and Microsoft, offering more energy-efficient and environment-friendly products.

In the past when I have discussed Green Data Center initiatives in India, the response many times is “we are a rich country we don’t need to be worried about energy efficiency.” It looks like this mindset is changing.

According to Ravichandran, Intel's use of virtualization and grid computing enabled the company to save US$30 million in 2007 in capital purchases. "Since 2006, we have seen an 11 percent increase in server utilization, which will allow Intel to save approximately US$77 million in 2008 capital purchases," he said.
