You’d never guess it, but your PC puts about 1,000 pounds of carbon dioxide into the atmosphere every year.
Computers have become, indirectly, a significant source of greenhouse gases, according to Kevin Klustner, CEO of Verdiem, a start-up that has devised software for curbing electricity consumption by PCs. That electricity often comes from coal-fired plants that release carbon dioxide.
Often, the power gets expended for no good reason.
“Thirty percent of the energy consumed by a personal computer is wasted because people aren’t in front of it,” Klustner said.
