Green IT: Corporate Strategies

(page 3 of 3)

Whereas Forrester and Gartner's reports concentrated on green IT, the McKinsey report focuses on a broader sense of energy efficiency, to include office buildings as well as devices and products. The authors argue that implementing such energy efficiencies could offset 85% of projected energy demands by 2030. That's considerably more impact than increasing fuel efficiency in vehicles, replacing industrial equipment and industrial processes that are not energy efficient, planting forests and improving soil, or shifting toward renewable energy sources. Citing projections from the Energy Dept., the report's authors state that overall energy use in commercial environments is predicted to rise at 1.6% each year for the next 22 years. The energy used in offices full of PCs and power-guzzling devices is expected to grow at twice that rate.

What each of the three reports share is statistics that make it clear reducing expenses is the leading reason corporations are seeking more eco-friendly practices. Forrester's report, for instance, states that 55% of those surveyed see reducing their energy-related operating expenses as the main reason for pursuing more sustainable IT operations—above "doing the right thing for the environment," the top motivator for 50% of those polled. In the Gartner report the authors estimate that "potential power cost and CO2 emission reductions of 50% are available" by better managing the power usage of PCs, monitors, and printers—for instance, simply encouraging employees to turn them off.

Going Green Can Mean Dollars Saved

And the McKinsey document, helpful as a macro-view of how the U.S. can adopt more environmentally friendly practices, concludes that corporations, governments, and individuals alike can slash greenhouse emissions 50% from projected levels in 2030 by using technologies that already exist—as well as those in the pipeline. The report also says 40% of the recommended practices would save companies and organizations money too.

In other words, going green can mean dollars saved—clearly a motivating factor for the tech companies already pushing for more earth-saving IT policies, not to mention for those corporations outside the realm of tech that look at such reports to gauge how policies are evolving—and how to emulate them.
