| Abstract | If solar panels and wind turbines can generate direct current (dc) voltage, and all electrical and electronic loads can operate directly off dc voltage, why is the distribution network within the built environment an alternating current (ac) system? In a world where carbon footprint is in focus, why are systems dc–ac–dc and not dc–dc–dc? Historically, voltage drop and therefore the need for larger gauge wiring were seen as technical and economic barriers to extra-low dc voltage systems. However, prices and power needs have lowered, it is now technically and economically feasible to use dc systems for the built environment. Such systems can provide energy independence and energy security. Examples of niche usage of solar photovoltaics that are providing electricity in the developing world are used to show that distributed dc voltage can have direct positive impacts on many of the UNs, sustainability development goals. Given the advantages of distributed dc electricity systems over centralised ac systems, it is concluded that policy makers and NGOs have to take on board dc as a sustainable solution to help the billions of people that either are not connected to electricity or use fossil fuels that are adversely effecting there health. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
