Abstract

Hidroenergija je obnovljiv, ali nije i održiv („zelen“) i čist način proizvodnje električne energije i umanjivanja utjecaja klimatskih promjena. Održivost pretpostavlja isključivanje daljnjeg uništavanja ili većih šteta na važnim riječnim ekosustavima i biološkoj raznolikosti, a hidroelektrane i brane imaju ogroman i nepopravljiv učinak na okoliš, prirodu i društvo, kao što su: prekinuti kontinuitet toka rijeke, promjene životnih uvjeta, promjene režima pronosa sedimenta, onemogućena veza s okolnim površinskim i podzemnim vodama, šteta ribljeg fonda te utjecaj akumulacija na mikroklimu okolnog područja. Biološki/ekološki aspekti najčešće nisu obuhvaćeni energetskim politikama. Mnoge europske direktive i međunarodni dokumenti odnose se na ovaj problem, ali je njihova provedba tek u začecima, a promjena je nužna odmah kako bi se spasile preostale nepromijenjene, prirodne rijeke i sačuvala biološka raznolikost slatkovodnih ekosustava u Hrvatskoj, ali i općenito u svijetu.

Abstract (english)

Hydroenergy is restorable, but not sustainable („green“) and clean way of producing electric energy and reducing climate changes. Sustainability means that there is no further destruction or bigger damages in important river ecosystems and biodiversity. As we can see, hydroelectrics and watergates have huge and ireclaimable influence on environment, nature and society, as discontinued river flow, changes of life conditions, changes in mode of sediment transfer, disabled connection with surrounding water above and in the ground, damage on fish fund and influence of reservoir on microclime of surrounding area. Biological/ecological aspects usually are not included by energetic politics. Many European directives and international documents take care of this problem, but their enforcement is still in the beginning, and changes are neceseary to save those rivers that are still natural and to save biodiversity of freshwater ecosystems in Croatia and in the world.
