Obnovljivi izvori energije su vrsta resursa koji se prirodno obnavljaju. Oni se ne mogu potro\u0161iti upotrebom ili potro\u0161njom zbog svog prirodnog obnavljanja.\u00a0<\/span><\/p>

\u00a0<\/p>

Obnovljiva energija je vitalna za tranziciju ka odr\u017eivijoj i \u010distijoj energetskoj budu\u0107nosti. Razvoj tehnologija obnovljive energije podsti\u010de inovacije i stvaranje novih radnih mesta. Obnovljiva energija smanjuje zavisnost od fosilnih goriva i podr\u017eava globalne napore u borbi protiv klimatskih promena.<\/span><\/p>

Nakon \u0161to se vekovima energija fosilnih goriva koristila (jo\u0161 uvijek se koristi), danas se globalna slika menja, a obnovljiva energija se smatra klju\u010dnom za budu\u0107i razvoj Zemlje.<\/span><\/p>

Izraz \u201c100% obnovljiva energija\u201d (eng. 100% renewable energy) podrazumeva situaciju u kojoj se sva potreba za energijom zadovoljava isklju\u010divo koriste\u0107i obnovljive izvore energije.<\/span><\/p>

\u00a0<\/p>

Tehnologije obnovljive energije koriste snagu sunca, vetra i toplotu Zemljine unutra\u0161njosti, a zatim je pretvaraju u upotrebljive oblike energije poput toplote, struje i goriva.<\/span><\/p>

Iako \u010desto nije u centru pa\u017enje, hidroelektrane su najve\u0107i obnovljivi izvor elektri\u010dne energije, zatim vetar, pa solarna energija.<\/span><\/p>

\u00a0<\/p>

  1. Vetar<\/span><\/li><\/ol>

    Vetroturbine koriste velike lopatice rotora, postavljene na visokim visinama, na kopnu i na moru, kako bi uhvatile kineti\u010dku energiju koju stvara vetar. Rotor je povezan sa turbinskim generatorom, koji se okre\u0107e da bi pretvorio kineti\u010dku energiju vetra u elektri\u010dnu.<\/span><\/p>

    \u00a0<\/p>

    1. Solarna energija<\/span><\/li><\/ol>

      Solarne tehnologije hvataju svetlost ili elektromagnetno zra\u010denje sunca i pretvaraju ga u elektri\u010dnu energiju. Sposobnost solarnog sistema da proizvodi elektri\u010dnu energiju zavisi od poluprovodni\u010dkog materijala, zajedno sa uslovima okoline kao \u0161to su toplota, prljav\u0161tina i senka.<\/span><\/p>

      \u00a0<\/p>

      1. Geotermalna energija<\/span><\/li><\/ol>

        Geotermalna energija poti\u010de direktno iz Zemljinog jezgra \u2013 toplota se stvara klju\u010danjem podzemnih rezervoara vode, poznate kao geotermalni resursi.<\/span><\/p>

        Geotermalna postrojenja obi\u010dno koriste bunare za pumpanje tople vode iz geotermalnih resursa i pretvaraju je u paru za turbinski generator. Izva\u0111ena voda i para mogu se zatim ponovo ubrizgati, \u010dine\u0107i ih obnovljivim izvorom energije.<\/span><\/p>

        \u00a0<\/p>

        1. Hidroenergija<\/span><\/li><\/ol>

          Hidroelektrane kanali\u0161u kineti\u010dku energiju iz teku\u0107e vode u elektri\u010dnu energiju koriste\u0107i turbinski generator. Hidroelektrane se obi\u010dno nalaze u blizini vodnih tela i koriste strukture za skretanje kao \u0161to su brane za promenu protoka vode. Proizvodnja energije zavisi od zapremine i promene nadmorske visine ili visine vode koja te\u010de. Ve\u0107e koli\u010dine vode i ve\u0107i naponi proizvode vi\u0161e energije i struje, i obrnuto.<\/span><\/p>

          \u00a0<\/p>

          1. Biomasa<\/span><\/li><\/ol>

            Biomasa \u2013 organski materijal poput drveta, suvog li\u0161\u0107a i poljoprivrednog otpada se obi\u010dno sagoreva, ali se smatra obnovljivim jer mo\u017ee da se ponovo uzgaja. Sagorevanjem biomase u kotlu proizvodi se para visokog pritiska, koja rotira turbinski generator da bi proizvela elektri\u010dnu energiju.<\/span><\/p>

            Biomasa se tako\u0111e pretvara u te\u010dna ili gasovita goriva za transport. Me\u0111utim, emisije iz biomase variraju u zavisnosti od materijala koji se sagoreva i \u010desto su ve\u0107e od drugih, \u010distijih izvora energija<\/span><\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"
