In terms of renewable energy sources, Slovenia has the greatest privilege in being able to utilise hydropower and wood biomass for energy uses. The paper discusses the importance of implementing multipurpose and goal-oriented projects such as hydropower plants (HPPs), which fulfil a number of strategies set by the state and local communities. Since every human intervention in the environment has certain impacts, the paper shows how synergistic effects can be created between environmental protection and energy sector development through responsible environmental planning and implementation of the best possible measures, drawing from a practical example of the multipurpose construction project of HPPs on the lower course of the river Sava. The paper addresses the issue of fish migration and barriers in watercourses, presenting the current situation in Slovenia and worldwide. It also examines the success of fish passes at HPP Arto-Blanca, based on several years of monitoring. Such passes enable fish to migrate past hydropower plants, maintain healthy fish populations, preserve genetic diversity, and ensure the connectivity and preservation of the entire aquatic ecosystem. The example of the future Mokrice hydropower plant illustrates the trend and commitments in the planning of such passes in the futureGeostrateška situacija v svetu opozarja, da je za državo, ki želi biti suverena, nujno, da čim prej okrepi stopnjo samooskrbnosti z energijo in hrano ob sočasni skrbi za vzdržni okoljsko-družbeni razvoj. Slovenija ima na področju obnovljivih virov energije največji privilegij v koriščenju hidroenergije in lesne biomase. V prispevku je obravnavan pomen izvajanja večnamenskih in ciljno usmerjenih projektov, kot so hidroelektrarne, ki izpolnjujejo več zadanih strategij države in lokalnih skupnosti. Upoštevajoč dejstvo, da ima vsak človekov poseg v prostor določene vplive, je na praktičnem primeru večnamenskega projekta izgradnje HE na spodnji Savi prikazano, kako se lahko z odgovornim okoljskim načrtovanjem in izvedbo najboljših možnih ukrepov ustvarijo sinergijski učinki med varovanjem okolja in razvojem energetike. Predstavljena je tematika ribjih migracij in pregrad na vodotokih, prikazano aktualno stanje v Sloveniji ter po svetu in na podlagi večletnih monitoringov obravnavan primer uspešnosti ribjega prehoda pri HE Arto-Blanca. Tovrstni prehodi omogočajo ribam: migracijo mimo hidroelektrarn in ohranjajo zdrave populacije rib; vzdrževanje genetske raznolikosti; povezanost in ohranitev celotnega vodnega ekosistema. Na primeru bodoče HE Mokrice so predstavljeni trend in obveze pri načrtovanju tovrstnih prehodov v prihodnjeTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Mariboru, Fakulteta za energetiko
