This working paper is part of an ongoing effort at documenting the deployment of renewable energy technologies in productive enterprises. For the purposes of this study, the focus is on-farm and off-farm enterprises that are, or have the potential of, making use of renewable energy for value addition. The paper analyses three value chains from the HKH – bamboo in Bangladesh and Myanmar, yak milk in China and Bhutan, and tourism in Nepal and India – with the objective of highlighting the energy needs in each segment, existing energy flows, and the opportunities for renewables to strengthen constituent enterprises.
