Abstract

Splitsko-dalmatinska županija svojim potencijalom obnovljivih izvora energije, u kojem prednjači sunčeva energija, u stanju je osigurati nesmetani vlastiti gospodarski razvoj uz znatno smanjenje emisija CO2, te dodatno doprinijeti Republici Hrvatskoj u mjerama koje se provode na smanjenju emisija CO2 u energetskom sektoru. Da bi se dokazala postavljena hipoteza nužno je imati i bilancu neposredne energetske potrošnje. Zadnja snimka stanja energetske potrošnje Splitsko-dalmatinske županije izrađena je za 1996. godinu. U radu su definirane metode za računanje potrošnje Splitsko-dalmatinske županije prema podacima o potrošnji Republike Hrvatske za određenu godinu. Metode se temelje na udjelima u energetskoj potrošnji Splitsko-dalmatinske županije u potrošnji Republike Hrvatske za 1996. g. Na taj način se došlo do bilance neposredne potrošnje energije Splitsko-dalmatinske županije u 2003. g., te su određene energetske potrebe Splitsko-dalmatinske županije do 2020. g. i to za dva moguća scenarija. Referentni scenarij je pretpostavio razvoj korištenjem uobičajenih oblika energije, zasnovan je na gorivima fosilnog podrijetla, uz zanemarivo uključivanje obnovljivih izvora energije i novih tehnologija za njihovu primjenu. Da bi se mogao uraditi drugi, ublaženi scenarij, koji u bilancu energetskih potreba maksimalno uključuje obnovljive izvore energije, trebalo je istražiti koliki je njihov potencijal u Splitskodalmatinskoj županiji. Obrađeni su potencijali sunčeve energije, energije vjetra, malih hidroelektrana i energije biomase, uz postojeći potencijal hidroelektrana. Provedenom analizom pokazalo se da je njihov potencijal dostatan za energetski razvoj do 2020. g. U radu je korištena IPCC metodologija izračuna emisija stakleničkih plinova iz energetskog sektora. Prema njoj izračunate su emisije CO2 iz energetskog sektora Splitsko-dalmatinske županije za oba scenarija. Obrađeni su i specifični troškovi primjene obnovljivih izvora za smanjenje emisija i urađeno je investicijsko vrednovanje ublaženog scenarija u odnosu na referentni scenarij. Razrađena je metoda kojom su izračunate ukupne emisije stakleničkih plinova. Svi provedeni proračuni prikazani su grafički i tabelarno. Dobiveni rezultati su prikazani i uspoređeni u posebnom poglavlju. Postavljena hipoteza je potvrđena u cijelosti. Rezultati su u zaključku prokomentirani.

Abstract (english)

The Split-Dalmatia County has a significant potential of renewable sources dominated by the solar energy. It is therefore capable of providing energy for its economic development and considerable reduction of CO2 emissions with the additional contribution to the Republic of Croatia in measures carried out to reduce CO2 emissions in energy sector. To prove this hypothesis, among other things, it is necessary to have the balance of the immediate power demand. The latest power demand data in the Split-Dalmatia County available is for the year 1996. The paper defines the methods for calculating the Split-Dalmatia County demand in relation to the Republic of Croatia demand in 1996. In this way the balance was calculated for the immediate Split-Dalmatia County power demand in 2003, based on which the Split- Dalmatia County power needs were calculated for the two scenarios until 2020. The referent scenario implied the development by using the usual types of energy based on the fossil fuels, with irrelevant involvement of renewable energy sources and new transformation technologies. In order to make a new tempered scenario, which includes maximum renewable energy sources in the balance, it was necessary to find out their potential in the Split-Dalmatia County. The solar energy, wind power, small hydroelectric plants, and biomass energy were treated together with the existing hydroelectric plants potential. The performed analysis showed that their potential is sufficient for energy development by 2020. The IPCC method of calculating greenhouse gas emissions from the energy sector was used. Using it the CO2 emissions for the Split-Dalmatia County energy sector were calculated for both scenarios. The specific costs of renewable energy sources in emission reduction were also calculated and the evaluation was made for the tempered scenario in relation to the referent scenario. The method was developed for the calculation of the total greenhouse gas emissions. All carried out calculations are shown graphically and in tables. The obtained results are shown and compared in the separate chapter. The set hypothesis was completely proven. The results were commented in the conclusions.
