we have developed and demonstrated numerous small-scale, energy-saving technologies, most of which can be built and maintained locally. These include:



Hydraulic ram pumps for lifting irrigation and drinking water.

Solar room-heating systems to combat the freezing winters.

Solar water heaters and cookers.

Photovoltaic power for lighting.

Micro-hydro installations and small wind turbines for electricity production.



This work has helped to generate something of a renewable energy revolution in Ladakh. Many of the technologies have been taken up on a large scale by government and other voluntary agencies.
