12: The Future of Green IT for Corporations 209

6. Make Use of Rebates and Incentives

Chapter 4, “The Government’s Role—Regulation and EPA Activity,” and
Chapter 5, “The Magic of ‘Incentive’—The Role of Electric Utilities,”
describe the rebates or other incentives that encourage businesses to update
equipment and adopt efficient operational practices. These practices can help
reduce peak and total power demands, and that’s what makes the electric
power utilities happy.
Chapter 3, “Collaboration Is Key for Green IT,” describes how going to
green IT on a worldwide basis requires the collaboration of many different
groups, including electric utilities, government agencies, IT technology ven-
dors, data center design and build businesses, and all companies and organi-
zations worldwide, including your company. That’s one of the best things
about green IT as a step toward solving the energy crisis—we can all partici-
pate. The case studies in Chapter 9, Chapter 10, “Green IT Case Studies for
Universities and a Large Company,” and Chapter 11, “Worldwide Green IT
Case Studies,” and Appendixes A through D give details on how other com-
panies have implemented green IT.

Green IT for the Future

According to a 2008 article in ComputerWorld, “Green computing promises
an enormous win for IT: a chance to save money—and the environment. Many
companies are trying to go greener, but a few truly stand out.” Many compa-
nies have begun to address some of these challenges head on. In fact, between
30 percent to 50 percent of large enterprises have consolidated or started to
consolidate during 2008, and most are doing some level of virtualization.
Those that have really advanced these efforts are seeing significant returns or
savings. Some customers have shown the ability to do the following:

■ Triple asset utilization
■ Provision new resources in minutes
■ Reduce heat by up to 60 percent
■ Reduce floor space by as much as 80 percent
■ Reduce disaster recovery time by 85 percent

The following section describes one vision for a green IT future.
