The Greening of IT
38 How Companies Can Make a Difference for the Environment

Chapter Summary and Conclusions

You can reach the following conclusions from the discussion on green IT:

■ The huge expenditure of electrical power on IT has reached the point
where it has attracted both government and environmental attention.
■ The projection for additional IT applications will only exacerbate the sit-
uation if current inadequate and wasteful technology trends continue
unchanged.
■ Virtualization is the most-promising technology, addressing both the
issues of IT resource utilization and facilities space, power, and cooling
utilization.
■ Solutions and processes address the situation from end to end: at the
server end through power management features, and at the data center
end through integrated IT facilities modular solutions.

These conclusions should excite anyone in the IT industry, as the ways
ptg
to save energy in IT are pervasive enough that everyone can have a part
in improving a company’s IT energy efficiency.
