Since 1976 the National Center for Appropriate Technology has been serving economically disadvantaged people by providing information and access to appropriate technologies that can help improve their lives. During the organization's rich and varied history, NCAT projects have ranged from low-tech to high-tech, addressing complex issues of housing, economics, and environmental quality. Weatherizing houses, training farmers, monitoring energy use, demonstrating renewable energy technology, testing new products and providing information on building construction are just a few of the many ways that NCAT has contributed to fostering healthy quality of life for everyone.
