**4.1.1 Natural sources**

Natural sources include biomass gathered from natural resources such as fallen tree branches, woody weeds, etc.

### **4.1.2 Energy crops**

Energy crops include biofuel as sole or principal product such as trees, grasses, and sugarcane, sorghum and oil crops. In addition, biofuel co-production is also part of energy crop category. Biofuel-co-production is a pre-planned multi-output production including biofuel i.e. sugarcane to produce sugar, ethanol, electricity, timber or tree-fruit production to deliver thinning and harvest waste as biofuel.

Generation of biofuel is expected to increase in the near future. A policy for biofuel has been developed by the government. The government is keen on development and generation of biofuel for the benefit of the country. More local or international investors are expected to participate fully in the production of biofuel and thus enhance the energy mix of the country. Availability of renewable energy sources varies depending on their attractiveness to the end user. Biomass differs markedly from conventional fuels and other renewable sources by having a wide range of competing use such as food, fodder, fibre, agricultural fertilizers, fuels, etc. In many places, some types of biomass are less valuable as resource energy than as source fulfilling other needs.

Potential of biomass sources (non-wood) in the country are given in Tables 7.

Estimated average annual production levels of wood fuel and its associates such as tannin residue are shown in Table 8.
