Brian Won of Ars Technica writes: "For years and years, computing was all about performance. Faster CPUs, better video cards, more RAM-all to make sure you had the biggest and baddest box on the block. Recently, we've seen a new trend, focused mainly on lower-energy, more efficient computing. The marketing buzz says that a green PC will result in reduced power bills, smaller servers, and lower carbon footprint for the environment. Couple this lean approach with reductions on hazardous substances (a la RoHS) that have been made over the past two years, and computing is clearly becoming less wasteful."
