Energy derived from wind energy is acceptable because of all the forms of energy source it has the least harmful impact on the environment. The installation of a wind farm is much more expensive compared to energy sources that emit CO2, but it is more cost-effective and environmentally friendly in the long run. The main advantage of installing a wind farm is that it does not release harmful CO2 by burning fossil fuels. Wind farms produce clean energy using wind potential at the site where they are installed. The factor that tells us that it is high time to turn to renewable energy is our planet which is currently in a phase of global closure. Global warming does not come suddenly but is the product of the use of resources from non-renewable energy sources. For many years people were the only source of energy while renewable energy sources such as wind, solar and water energy were put in the background because they were not sufficiently researched and gave too little product compared to non-renewable sources. A similar approach was used on the Campus of the University of Rijeka, where the use of any form of renewable energy is not planned, although the Campus is located in a very windy position on Trsat. Therefore, an analysis of the installation of a wind farm on Campus was conducted in this work. Although accurate data on wind speeds for the Campus area are lacking, an approximate calculation can show that the use of wind energy can be not only environmentally friendly, but also economically viable.
