Sub-Saharan Africa continues to suffer from a major energy deficit, with hundreds of millions of people lacking access to electricity and clean cooking fuels. There is a great need for innovative mechanisms that can help families access clean and affordable energy. The Carbon Initiative for Development (Ci-Dev) is one such mechanism.  
 
A $125 million fund with a pipeline of 14 pilot projects in Africa, Ci-Dev will help improve living standards and sustainable energy through results-based finance. Along the way, it will generate valuable lessons in how reducing greenhouse gas emissions can generate tangible development benefits for local communities, like cleaner air, improved safety, and financial and time savings.

These lessons can help in the delivery and scale up of innovative climate finance business models.

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.
