STG (previously operating as the Solar Turbine Group) is a non-profit organization based in Cambridge, Massachusetts whose mission is to provide technical, financial and intellectual support, assistance, and training to projects and organizations focused on bringing sustainable energy technologies to communities across the developing world.
Our Vision

Access to an affordable, distributed, renewable form of energy generation can improve productivity and quality of life in rural villages, clinics, schools, and organizations without significantly increasing their carbon footprints. The development of a solar technology that can be locally customized, manufactured, and distributed will promote local economies while extending energy access beyond the traditional electricity grid.
