This thesis seeks to determine the most effective means of distributing appropriate sustainable energy technology to individuals that have no access to energy services. There are approximately 1.4 billion people around the world that are 'energy-impoverished.' ASETs are small-scale clean energy technologies that fill the immediate energy needs of these individuals. There are, however, seven fundamental barriers limiting the dissemination of these technologies. These barriers result from the microeconomic and sociological conditions of these populations. This thesis analyzes 12 unique distribution models from companies, nonprofit organizations, and universities, and shows how each model performs relative to these barriers. Following this analysis, I propose the most effective means of distribution ASET to energy-impoverished populations.
