When Electronics Go Green, Everybody Wins
December 8, 2008 6:25 am | by Jeff Ittel, senior vice president of semiconductors, Avnet Electronics Marketing | Articles | CommentsFor members of the electronics supply chain, going “green” is not just a short-term marketing scheme rife with buzzwords but short on substance. Granted, the tech sector has jumped on its share of bandwagons, but this movement is different. It’s not just about pioneering technologies, building a positive public image, padding the bottom line or even “doing the right thing.” It’s all of the above. When state-of-the-art electronic products are energy efficient, environmentally sustainable, and cost effective, everyone wins.
