Bachelor Thesis from the year 2015 in the subject Engineering - Power Engineering, grade: 1,3, University of Applied Sciences Münster (Fachbereich Wirtschaft), language: English, abstract: This paper takes into account various effects the use of wind energy has on different levels of the environment. The most promising benefits and pressing challenges will be presented to allow for a differentiated assessment of the sustainability performance of wind energy as a power source. This will also be done in comparison to other forms of energy generation both fossil and renewable ones. From supply chain perspective, the paper will focus on the supply of rare earths as an input material to wind turbine manufacturing. The reasons for which this is to be considered the most questionable aspect of the supply chain will be explained as well as solutions proposed for how effective supply chain management can help improve the situation.
