Internet Reducing American Energy Use
The internet is saving 10 times the energy required to run an internet-linked computer.
Remember when renting a movie required a trip to the video store or checking a bank balance required a visit to the bank? Now, anything from used books to driving maps are just a click away. Telecommuting is common and taxes can be submitted electronically to the IRS. The internet is shaping our lifestyles, allowing us to save energy.
A recent study by the American Council for an Energy Efficient Economy (ACEEE) discovered that every kilowatt-hour of electricity used to power communications and information technologies is resulting in a 10 fold increase in energy savings.
“Acceleration of information and computer technology across the US landscape post 1995 is driving much of the nation’s energy-productivity gain,” says John Laitner of the ACEEE and coauthor of the study. “Had we continued at the historic rate of prior years, we would today be using the energy equivalent of 1 billion barrels of oil more [per year] than we were” in the early 1990s.

Energy intensity is a measurement of the quantity of energy required to produce one dollar of output and is a good indicator of overall energy efficiency. After the oil embargo, the energy intensity in American fell sharply. From 1986 to 1996 however, energy efficiency improvements fell to under 1% annually.
Around 1995, the use of the internet began to increase significantly. Remarkably, from 1996 to 2001, energy intensity fell by an average of 2.9% annually. This trend has continued since 2001 at a pace of 2.4% annually, with half of it being attributed to technology gains.
The energy saving impacts of information and communications technology can expand through mindful use. Purchasing models that consume less energy, selecting optimal energy settings, and using a laptop instead of a PC all save electricity.
I am happy to know that my beloved computer is helping me to reduce my energy use and studies such as this remind me of how technology can be used as a tool for a greener lifestyle. The future potential is staggering as energy costs increase, concern of climate changing mounts, and the use of the internet expands over time.
Internet Helps Americans Save More Energy Each Year
Printers consume a huge amount of resources including electricity. I put everything on my hard drive, then review it at the end of the quarter, and commit what I want to keep to a DVD after compressing. Paper bills, ink bills and power bills have all dropped, as well as aggravation with printers and piles of used and now useless paper.
And this is with many computers using a lot of energy! In total, my many computers probably take over a kilowatt. I suppose I might be a bit above average, but if there is a movement towards more efficient computers instead of fast ones, I’m sure these numbers could improve even more. Maybe the new, cheap, linux-based PCs (like the Asus Eee and Walmart PC) will help that.
The manufacture of paper is also uses a lot of energy. Those are all good tips.
Paper-making also uses a tremendous amount of water. Can’t remember how much (it was twenty years ago), but it’s a lot. Envelopes from paper bills and junk mail often make good scrap paper. Reuse centers often have industrial paper scraps, cut to useful sizes. Check around your local area - I haven’t had to buy new paper in years. Saves a lot of money, too. But Mom will have to get used to getting her letters on the blank side of junk mail.
