Healthy industrial city in Century 21 using renewable energy sources

Depletion of world fossil fuel reserves as well as environmental problems make it compulsory to think of new options with regard to heating of premises. We discuss the potential and economic feasibility of solar, industrial process-heat applications. In this paper, an analysis is developed to determine the necessary electrical energy to obtain the required quantity of heat. Additionally, this quantity of heat realizes the temperature rise according to the sort of operation and type of materials. The work presents a new modified energy system for industry. This modified system is a stand-alone photovoltaic system for small workshops and hybrid renewable energy sources according to the required load and the location of the industrial city to prevent pollution. The nature of workshops and its industrial products are the basic factors in the work. The results give an idea about the sizing of renewable energy system. Finally, by applying this study, a healthy and clean area can be realized. This work also discuss the small scale optimization problem for minimizing the output electrical energy of the heat required of each group for the required process subject to the boundary limits of their temperatures.
