Apstrakt

Na osnovu podataka Energetskog bilanasa Republike Srbije za 2017. godinu, potrošnja finalne energije je procenjena na 8429 Mtoe, od čega je 48% ukupne potrošnje u sektoru domaćinstva, poljoprivreda i javno-komunalne delatnosti. U ukupnoj strukturi korišćenja finalne enrgije, obnovljivi izvori energije (samo geotermalna energija i biomasa zajedno) učestvuju sa 12%. Osim kvantitativne (energijske) analize, za potpuno razumevanje svih važnih aspekata korišćenja energije i uspostavljanja odgovarajuće energetske politike, potrebno je izvršiti i kvalitativnu (eksergijsku) analizu, kao i analizu uticaja korišćenja različitih energenata na životnu sredinu. Cene energenata treba da odražavaju vrednost iskoristivog dela, odnosno kvalitet, njihove energije, tj. eksergije. U radu je prikazana termodinamička i ekonomska analiza korišćenja različitih energenata u stambenoj zgradi grejane površine oko 160 m2, za klimatsko područje Beograda. Poređeni su različiti energenti za grejanje i pripremu sanitarne tople vode: električna energija, prirodni gas, daljinsko grejanje, ugalj i obnovljivi izvori energije. Dat je uporedni prikaz potrebne primarne energije, emisije ugljen-dioksida, eksergije, kao i cena energije i eksergije za različite energente.
