Clean/Cleaner technology

Clean technology includes those technologies that produce energy with little or no greenhouse gas emissions or nuclear waste, from sources such as wind, solar, biomass, hydro, and clean fuels, as well as energy-efficient techniques in information processing, electric motors, lighting, and many other usages. It also refers to any technology humans use that has a smaller environmental footprint than previously usage. One example is green buildings – structures that are both more energy-efficient and environmentally benign, compared to previous structures. Some new houses can produce more energy than they consume.
