This document discusses appropriate technology and how makerspaces and hackspaces can help advance it. Appropriate technology focuses on small-scale, labour-intensive, energy-efficient, and locally-controlled solutions. It remains relevant given many lack access to resources. The document outlines benefits of access to energy and issues that can arise. It provides examples of appropriate technology projects and discusses how makerspaces could introduce local production, share knowledge, and help test and fund new ideas to better connect problems to solutions.
