Abstract
ABSTRACT The demand for electrical energy is constantly growing. Power generation from renewable sources will play a role in meeting the electricity demand. Floating photovoltaics is a solution that still needs to be explored in the design and construction phases. The floating system has important characteristics: it reduces evaporation of water and algae growth in the basins, it does not occupy land and has a high efficiency due to the evaporative cooling effect. Multi-criteria decision analysis is used to determine the best technology, between fixed or tracked structure, on a system in Sicily. Analysis provided results regarding the superiority of horizontal axis tracking systems; the Levelized Cost Of Electricity is 64.37 USD/MWh and the avoided CO2 emissions are 23,491.60 tonnes.
期刊介绍：
Engineering and sustainable development are intrinsically linked. All capital plant and every consumable product depends on an engineering input through design, manufacture and operation, if not for the product itself then for the equipment required to process and transport the raw materials and the final product. Many aspects of sustainable development depend directly on appropriate and timely actions by engineers. Engineering is an extended process of analysis, synthesis, evaluation and execution and, therefore, it is argued that engineers must be involved from the outset of any proposal to develop sustainable solutions. Engineering embraces many disciplines and truly sustainable solutions are usually inter-disciplinary in nature.
