Environmental impacts of renewable energy sources in Slovenia

V Sloveniji pridobivamo električno energijo iz mnogo različnih obnovljivih in neobnovljivih virov energije. Vsak vir energije ima drugačen vpliv na okolje. Postavimo si vprašanje kakšen in kako velik je ta vpliv. V zaključni nalogi smo raziskovali in primerjali vplive posameznih virov električne energije na okolje v Sloveniji. Primerjava je bila izvedena na podlagi analize življenjskih ciklov. V programskem okolju GaBi Thinkstep smo uporabili metodo CML2001, AWARE, analizo porabe primarnih virov in analizo emisij PM delcev v ozračje. Rezultati analiz več okoljskih vplivov so pokazali, da niso samo neobnovljivi viri energije onesnaževalci okolja, temveč tudi obnovljivi viri energije pomembno prispevajo k onesnaževanju. Prav tako so rezultati prikazali, da je pri analiziranju okoljskih vplivov pomembno obravnavati celotni življenjski cikel pridobivanja, od rudarjenja surovin do razgradnje oziroma ponovne uporabe.In Slovenia, electricity is generated from many different renewable and non-renewable energy sources. Every source of energy has a different environmental impact. The question arises as to what and how big this impact is. In the presented thesis we investigate and compare the impact of individual source of electricity on the environment in Slovenia. The comparison is based on the life cycle analysis. In GaBi Thinkstep program we use methods CML2001, AWARE, primary source consumption analysis and analysis of emissions of PM particles into the atmosphere to analyze impacts. The results of analyzing several different environmental impacts show that non-renewable sources of energy are not the only pollutants, but renewable energy sources also importantly contribute to pollution. The results also show that when analyzing environmental impacts, it is important to consider the entire lifecycle of production of energy, from mining of raw materials to degradation or reuse
