Appropriate Technology

The isolation and remoteness of the Ladakh Region makes centralised energy distribution models, neither feasible nor viable. Extreme weather conditions with a prolonged winter season, when temperature falls below zero degree Celsius, remoteness and a crucial scarcity of natural sources of energy like “fuel wood” renders life difficult in the region. Therefore, it is not at all difficult to understand the importance of a daily energy need for the Ladakhi people. Various programs of government agencies for the provision of clean energy sources like electricity and natural gas have not reached majority of Ladakhi people, which has, hence, deprived remote villages of basic need facilities.

This is the prime reason which led LEDeG to bring in intervention which aimed at providing a platform for Community Based Services (CBS), so that the Basic Need Services (BNS) could be facilitated. The first step towards this aim was to encourage a decentralised model of energy production and distribution, using local renewable
resources. These are mainly sunlight and water resources which are found abundantly in the region.

LEDeG has worked on a wide variety of appropriate technologies by carrying out adaptive research and feasibility studies vis-à-vis local conditions, needs and requirements. Presently, LEDeG has in-house expertise in propagation of various appropriate technologies, such as Micro Hydroelectric Power Units, solar waterheating

systems, Trombe wall technology, solar ovens, solar parabolic reflector cookers (both, for individual families and communities), hydraulic ram pumps, improved water mills and solar photovoltaic lanterns and house hold units. The main emphasis of LEDeG is on the ‘Decentralisation of Energy and Water Supplies’ (DEWAS) which fits the requirements and needs in the socio-cultural and geographic context of Ladakh.
