Abstract

Održivi razvoj je program koji se fokusira na poboljšavanje načina ljudskog života. Taj program uključuje ravnotežu okoliša, društva i gospodarstva. Proizvodnjom čiste i pristupačne električne energije iz vjetra se direktno utječe na dosta ciljeva održivog razvoja.
U završnom radu je prikazana veza između Agende 2030 i potrošnje električne energije u svijetu i u Republici Hrvatskoj. Provedena je i analiza rada vjetroturbina u različitim klimatskim uvjetima te je naveden i objašnjen utjecaj okolina na njihov rad. Prikazan je i razvoj vjetroturbina te promjena izbora materijala za lopatice vjetroturbina kroz povijest. Na kraju završnog rada je opisan izbor materijala na temelju funkcionalnosti, eksploatabilnosti, tehnologičnosti, cijeni i recikličnosti te su predložena svojstva materijala i sami materijali za pojedine dijelove lopatica vjetroturbine.
Polimerni kompoziti ojačani vlaknima su se pokazali kao najbolji materijal za lopatice vjetroturbine. Imaju manju masu od konvencionalnih materijala, vrlo dobra mehanička svojstva i otporni su na koroziju. Drvo se pokazalo kao vrlo dobra zamjena za polimerne kompozite ojačane vlaknima za određene dijelove lopatica. Napokon, utvrđen je i trenutno najveći problem u industriji proizvodnje čiste i pristupačne električne energije iz vjetra, a to je recikličnost lopatica vjetroturbina. Ponuđeni su neki načini recikliranja, ali to područje ima još mnogo prostora za napredak.

Abstract (english)

Sustainable development is a program that focuses on improving the way people live. This program includes the balance of environment, society and economy. The production of clean and affordable electricity from the wind directly affects many of the goals of sustainable development.
The thesis shows the connection between Agenda 2030 and electricity consumption in the world and in the Republic of Croatia. An analysis of the operation of wind turbine in different climatic conditions was also carried out, and the influence of the environment on their operation was stated and explained. The development of wind turbines and changes in the materials selection for wind turbine blades throughout history are also presented. At the end of the thesis, materials selection is described based on functionality, exploitation, technology, price and recyclability, and the properties of the materials and the materials themselves for individual parts of the wind turbine blades are proposed. Fiber reinforced polymer composites have proven to be the best material for wind turbine blades. They have a lower mass than conventional materials, very good mechanical properties and are corrosion resistant. Wood has proven to be a very good substitute for fiber reinforced composites for certain parts of the blade. Finally, the biggest problem in the industry of producing clean and affordable energy from the wind has been identified, and that is the recyclability of wind turbine blades. Some ways of recycling are offered, but that area still has a lot of room for improvement.
