Abstract The society is looking for renewable sources of energy for example, wind energy, geothermal energy, solar energy, and hydro energy because utilization of fossil fuels poses the threat to global warming. Among these renewable energy sources, utilization of solar energy has shown great potential for growth in the current international energy mix. This research combines both Multi-Criteria Evaluation (MCE) and Geographical Information Systems (GIS) techniques to assess the sustainability of land for the installation of solar farms in Isiolo county in Kenya.

Many towns in Kenya have been experiencing a rapid population increase due to rural urban migration. This, in turn as led to increased demand for housing facilities in these towns. The existing public utilities like Sewage Treatment Plant (STP) facilities have been affected by this rapid increase in population.
