What we didn’t plan was the myriad ways in which our online classes are so much more resource-conserving than their brick-and-mortar counterparts. Here are a few that come to mind.
No Driving — Instead of having each of our students burn a few gallons of gasoline getting to class (a lot of them are pretty far from campus), we use a few watts of electricity to deliver their classes electronically. They can participate in their classes anywhere they can get online, whether that’s at home, at work on a quiet night shift, at their favorite coffee shop, or from their hotel room while they’re traveling on business. It goes even further than that, because many of our faculty also teach their classes from home. Given that we have faculty who live in the Triangle, in Charlotte, and even out of state, that adds up to a lot of driving avoided by teaching and taking classes online.
No Buildings — We don’t need big spaces to gather faculty and students in the same room, so we don’t have to spend a bunch of money and resources building, heating, cooling, and lighting classroom buildings. That means fewer buildings and more green space for everyone, and it adds up to a substantial savings in terms of resource usage. Even with smart climate-control systems, classroom buildings take a vast amount of energy to heat and cool, and because of their scale, they have to be heated and cooled around the clock, even at night when no one’s around. By delivering our classes online to our students, we help reduce the pressure to build and maintain more resource-hogging classroom space. In fact, an online class full of students using their laptops at home, even if they leave them on all the time, still uses less electricity than it takes just to run the nighttime security lighting in a classroom building.
No Paper — Using online discussion boards, and writing, receiving, critiquing, and grading essays online saves reams of paper (literally) for each online class. My writing-intensive class has ten discussion boards, a prospectus, an essay, and a final revision. With twenty-five students in that class, assuming one full page each for the discussion boards, two pages for the prospectus, and ten pages each for the essay and revision, that’s (*does some math*) eight hundred pages that aren’t getting printed. Add in a syllabus that doesn’t have to get printed and handed out to the class, and that one 25-student online class has saved two whole reams of paper. Multiply that by the twenty-four classes we are offering this semester, and that’s a nice, heavy case of paper that isn’t getting deforested, pulped, packaged, shipped, and most likely ending up in a landfill somewhere at the end of it all.
So, less driving, less construction, less heating and cooling, and less paper. As a green freak, I gotta say that’s not too shabby as an accidental side effect. And here we were just trying to make it easier for you to go to class in your pajamas!
