This unit (NEF4205) of study aims to provide applied and creative knowledge and skills in the area of sustainable energy systems and environmental safety. The unit reflects on the concept of sustainability in the electricity generation sector in order to provide a broad and coherent body of knowledge for the consideration of future energy sustainability. The unit will first analyse conventional energy systems and the effect of emissions from these conventional energy systems. Then, renewable energy systems such as solar, wind, and hydro will be introduced and the significance of energy storage technologies will be diagnosed. Technical properties, environmental and economic advantages of these technologies will be discussed and learning activities will focus on mathematical modelling, design, and analysis of exemplar systems. Special emphasis will be given to the critical review of energy conversion principles in turbine based systems including wind and hydro turbines. Energy conversion efficiency and losses occurring during the transformation of mechanical energy to usable electric energy will be specifically diagnosed for a wind turbine case study. An introduction to acoustics, noise level measurements, properties of acoustic materials, and noise control for safe working environment will be delivered.
