Green technology encompasses a plethora of products and practices. What may initially come to mind — computers, TVs, MP3 players, cameras and so forth — is only the beginning. This broad category also includes alternative energy technology (wind, solar, geothermal, etc.), agricultural technology (organic food, plants, meat production and processing, etc.), architectural technology (energy-efficient buildings, etc.), automotive, industrial and much, much more. You'll find thorough coverage of green technology here on MNN. (Photo: Flickr)
