An article [1] I am writing this letter in order to explain my motivation for applying to Engineering Summer School of RWTH Aachen University. [2] I am applying for a sustainable energy technology course for different reasons. [3] I was born in an industrial region in a family of engineers and from childhood I wanted to carry on my parents' life work. [4] This winter I was in Berlin where I could see a lot of solar panels on the roofs, wind turbines outside the city, and I was also impressed by the excellent thermal insulation of the new buildings. [5] During high school, I made a decision about what I want to do in the future. [6] I knew that I wanted to be an engineer, but I could not decide in which area. [7] After visiting the heat power plant I realized that this technology of energy production will be a thing of the past. [8] And when my father said that such minerals as coal were exhausted and create problems more than good, I realized that I want to live in a clean world and be engaged in renewable energy sources. [9] From this point on, I’ve become very interested in electrical engineering. [10] I have got into the Kiev Polytechnic Institute into the Faculty of Electrical Engineering and Automation into the Department of Renewable Energy Sources and have become the deputy head of the group. [11] I take an active part in university life and attend scientific exhibitions and conferences in my free time. [12] I also was awarded a scholarship for academic achievements. [13] I have a strong interest to be an electrical engineer in the future. [14] I want to work on energy-saving and energy-efficient projects, which from ordinary residential, office and industrial buildings will make not only economical and environmentally friendly consumers, but also energy producers. [15] In this way, it will be possible to reduce the load on traditional power plants and subsequently replace them with clean power plants. [16] Higher results require us to be a better version of ourselves; we must constantly improve our skills, learn new things and develop acquirements. [17] Studying at Engineering Summer School of RWTH Aachen University will give me the opportunity to study new material together with people who think in the same way as I do. [18] Moreover, I have a good background. [19] I taught and successfully passed thermodynamics and heat and mass transfer in the past year. [20] I also studied object-oriented programming language C #, so there shouldn't be any problems
