Energypedia is a wiki-based platform for collaborative knowledge exchange on renewable energy and energy efficiency topics in developing countries.Today one in five people worldwide lack access to electricity, while every third person cooks on unhealthy fireplaces. First-hand knowledge on modern and sustainable energy solutions often only exists locally or in fragments and thus is difficult for individuals to access. Therefore, there is a great need to facilitate and expand the diffusion of these technologies in developing countries through knowledge exchange and collaboration.Recognizing that development in the 21st century requires that all actors have access to information, energypedia is working towards removing the knowledge barriers and expanding the diffusion of information addressing the topics renewable energy, energy efficiency and sustainable energy access for all. Through this platform we strive to create the right environment and provide the right tools for stakeholders engaged in the energy sector to collaborate, create and share knowledge and practical experience.On energypedia.info any registered user can easily create, modify and share content. Our users include energy practitioners, experts, academics and other interested stakeholders.
