Wow. That's also equal to 14.4 metric tons of carbon dioxide a year. Some 30% of corporate computers are left on overnight says whatcanonepersondo. Perhaps if companies realized how much they'd save, they'd turn them off. Any good idea--this time, good for the pocket book and good for the earth--takes people doing it on their own and passing the word to their friends and encouraging them to do the same. Then, it builds momentum and a world-scale dent is made. You gotta start somewhere. Turn your computers off when they're not in use and save yourself some money at the same time. posted originally from: AT:Hometech - Statistics and image via the whatcanonepersondo blog.
