Tips to Shrink Your Digital Footprint


When Google revealed the energy intensity of its data centers in 2011, it brought attention to the environmental implications of our information technology (IT) infrastructure. On the one hand, these technologies have allowed us to forgo travelling to distant meetings, store files electronically rather than cutting down trees for paper, and work remotely instead of spending long hours commuting. But the energy required for computing and storing data is growing rapidly. Here are some ways we can shrink our digital footprint:

  • Switch to the cloud. Encourage your workplace to consider storing digital assets offsite in a shared data center (otherwise known as the “cloud”). Most large data centers are more efficient than storage available on-site. Many data centers have sophisticated cooling technology, are better able to match server capacity with demand and increasingly make use of renewable sources of energy. Organizations under 100 users, especially, could cut their IT carbon emissions 90% by switching to the cloud. 
  • Ask IT companies to buy renewables. IT companies, like other businesses, are still getting most of their energy supply from coal-fired power plants and other polluting sources. The Greenpeace Cool IT Challenge urges IT companies to put forth innovation, mitigate their own carbon footprint, and advocate for significant policy changes in the mutual interest of business and the climate.
  • Choose efficient devices. According to the Natural Resources Defense Council (NRDC), much of the energy used in computing comes not from distant data centers, but from the devices we use every day. Efficient computers can use up to 80% less energy than their thirsty counterparts. Check out Energy Star for lists of the most efficient devices.
  • Utilize green apps for energy monitoring. Research shows that when people know how much energy they’re consuming, they use less. New software can deliver real-time information on the emissions generated by buildings, transportation, construction and more. For example, Oberlin College has a user-friendly web-based electricity and water monitoring system for their campus buildings. At the individual level, smart phones apps like Carbon Calc and Meter Reading can monitor energy use. Perhaps the greatest potential for IT is in its deployment for the smart grid.Ciscospaget
  • Check your power settings. Ensuring your computer automatically shuts down when not in use is the single biggest energy saving opportunity on most computers, according to NRDC. This can be achieved at the organization level too by managing power from a central server as Oakland University has done. Also keep peripherals like scanners and printers unplugged if you’re not using them.
  • Get certified. Some schools are now offering courses and or degree programs in green IT. Boston University offers a master in green computing. If sustainability isn’t a part of your IT training program, let the school’s administration know that they should offer such courses – green computing is the future of computing, after all.
  • Donate or recycle electronics. Much energy is expended producing and shipping electronic devices, so it’s vital to get as much “mileage” out of them as possible. Reusing electronics also keeps harmful metals and plastics from reaching landfills. The EPA maintains a list of places to donate used electronics.
