The project compares two potential alternatives that can be used to produce electricity. The University of Texas wants to know whether it should install silicon photovoltaic (PV) cells on the roofs of its parking lots or produce biofuel from algae in tubes. Photovoltaic cells harness energy from the sun and convert it into electricity using electrical components. Algae are a group of tiny organisms that use processes such as photosynthesis and fermentation to produce biofuels which are then used to generate electricity. After a functional, economic, environmental and societal analysis, our team recommended that the University of Texas move forward with the use of photovoltaic cells. The energy produced by photovoltaic cells was greater and had a much higher positive net present value than biofuel production from algae. The societal analysis of a design is of utmost importance and is the deciding factor whether a proposed design can move forward or not. The primary objective of this report is to identify a major societal issue in the designs and a rationale for the decision made in selecting the final design ...
