Appropriate technology is technology chosen in a way to be sensitive to its context of use.
Appropriate technology is generally considered to be that which is designed with the user in mind, and is often small-scale, often labor-intensive, energy-efficient, sustainable, and amenable to local maintenance and control.
The term "intermediate technology" was used by the economist Dr. E.F. Schumacher in his pioneering work, w:Small is Beautiful.
Appropedia is an active "sustainability wiki" with a focus on appropriate technology and developing country contexts.
Wikipedia has an appropriate technology category.
