There are quite a number of different alternative energies but in this paper Biogas will be analysed as a form of alternative energy in the context of sustainable development. A number of aspects need to be investigated if biogas is used as a form of energy supply. Criteria to consider include the availability of water and the area of agricultural land that needs to be used to supply the reactors with enough substrate to operate. Should energy crops be cultivated for the reactors, or is there enough other forms of substrate already available? There are factors to be taken into consideration such as whether to use the crops for food or fuel, area, water, labour and sustainability of the farmers.
