1- Model the first option (clearly define the variables), objective function and constraints 2- Solve the model using LINDO showing the optimal quantities of different energy sources and the objective function value 3- Identify the status of resources

In an effort to increase conformance to Sustainable Development Goals SDGs and meet smart cities criteria, the start-up company SDG-COIN, provided you with the data pertaining to several green energy sources. These sources are integrated/combined and synchronized and can be used at any point in time to provide their respective time dependent supply. As a part of your assignment, you were asked to devise an optimum scheduling plan of different energy sources so that the total cost is minimized. The technologies of these sources are available and can be installed without any delay. The company has given you the option of using the different sources without needing the installation because they can obtain the needed energy at given rates $/KWH directly from other suppliers. The relevant costs are given in table (1) for both Summer and Winter seasons (Assuming the whole year can be divided to Summer and Winter). The capacity in this case is not limited and all demand can be satisfied for this option.
