Providing village-level energy services in developing countries Meghan Bailey, Justin Henriques, John Holmes and Ruchi Jain Technical Report 1 October 2012 Key words: Off-grid energy, rural development, renewable energy Smart Villages We aim to provide policy makers, donors and development agencies concerned with rural energy access with new insights on the real barriers to energy access in villages in developing countries - technological, financial and political - and how they can be overcome. We are have chosen to focusing on remote off-grid villages, where local solutions (home- or institution-based systems, and mini-grids) are both more realistic and cheaper than national grid extension. Our concern is to ensure that energy access results in development and the creation of ‘smart villages’ in which many of the benefits of life in modern societies are available to rural communities. www.e4sv.org | [email protected] | @e4SmartVillages CMEDT – Smart Villages Initiative, c/o Trinity College, Cambridge, CB2 1TQ Publishing © Smart Villages 2016 The Smart Villages initiative is being funded by the Cambridge Malaysian Education and Development Trust (CMEDT) and through a grant from the Templeton World Charity Foundation (TWCF).
