Renewable biogas provides clean, affordable energy for rural households in Nepal

Trecking through the remote and rugged mountainous areas of Nepal, it was evident to me that the abundance of natural beauty starkly contrasted with the scarcity of access to affordable and environmentally sustainable energy sources.

In Nepal, Most households still rely on traditional energy sources for cooking and heating, such as firewood or agriculture residue with few having access to electricity.

The high demand for firewood has created a number of environmental problems such as deforestation, soil degradation, and flooding. Firewood also requires considerable time for families to collect and its use results in indoor air pollution which particularly impacts women and children.

A solution has been the introduction of biogas as a way to bring cleaner, safer, and more affordable energy to rural households. It is created when animal and human waste are converted into clean sources of cooking fuel, replacing the need for wood, dried dung, and fossil fuel based sources of energy. Its byproduct can also be used as a natural fertilizer to increase agricultural yield.
