Currently Bangladesh is facing a major problem in generating enough electrical power with conventional way like natural gas, coal, petroleum or hydroelectric power plants to fulfill the demand of the nation. To cope up this situation, it is very necessary to use non-conventional energy sources such as solar, wind, biogas, tidal, and geo-thermal energy etc. as the alternative sources of producing electricity of sufficient amount. All the possible types of solar panels as well as wind turbines and biogas reactors have been studied for maximum electric power generation with highest efficiency and minimum cost. This study opens a new pathway for all universities as well as public and private institutions to design and develop their organizations using this concept Combo-Renewable Campus i.e. using combination of renewable energy sources for meet up the demand of electricity.
