Green Tech was by no means prominent at Macworld 08, but there was still a pretty good amount on display. Environmental sustainability has become a major concern when it comes to technology products. Computers and most other electronic devices consume lots of energy while they’re living and produce lots of waste when they die. Hazardous waste, in many cases. But nearly all of the major manufacturers have begun thinking through the lifecycle of their products and designing them to have as little an impact on the environment as possible – not only because of the demand for Green Tech in the marketplace, but also because it’s just plain old good business.
