Abstract

Izvori iz kojih dobivamo energiju sve se više nalaze u centru pažnje strateških gospodarskih planova, osobito nakon donošenja Europskog zelenog plana. Obnovljivi izvori energije (OIE) igraju ključnu ulogu u Europskom zelenom planu koji ima za cilj da EU postane klimatski neutralna do 2050. godine. U tome su OIE neophodni za postizanje tog cilja. Poljoprivreda je sektor opće potrošnje koji zahtjeva značajne količine energije i nalazi se pod pritiskom da u svoje prakse uvede što veće količine energije iz ekološki prihvatljivih, obnovljivih izvora. Geotermalna energija jedan je od obnovljivih izvora energije koji pruža veliki potencijal uz minimalne negativne posljedice na okoliš. Hrvatska se nalazi na dijelu Panonskog bazena i ima značajan geotermalni potencijal. Cilj ovog rada je opisati mogućnosti primjene geotermalne energiju u poljoprivredi, s posebnim osvrtom na njezinu ulogu u stakleničkoj proizvodnji. Uz teorijski dio rada s opisom primjene geotermalne energije u različitim poljoprivredno-prehrambenim djelatnostima, u sklopu rada proveden je intervju s proizvođačem „Rajska rajčica“ (dio Zarja grupe) iz Svete Nedelje. Ova tvrtka u svojoj stakleničkoj proizvodnji rajčica koristi geotermalnu energiju za grijanje pri čemu, prema procjeni intervjuiranih predstavnika, ostvaruju uštedu do 80% u odnosu na grijanje različitim konvencionalnim energentima.

Abstract (english)

Sources of energy are increasingly at the center of strategic economic plans, especially after the adoption of the European Green Deal. Renewable energy sources (RES) play a crucial role in the European Green Deal, which aims for the EU to become climate-neutral by 2050. RES are indispensable in achieving this goal. Agriculture is a sector of general consumption that requires significant amounts of energy and is under pressure to introduce higher amounts of energy from environmentally acceptable, renewable sources into its practices. Geothermal energy is one of the renewable energy sources that offers significant potential with minimal negative environmental impact. Croatia is located in the part of the Pannonian Basin and has significant geothermal potential. The aim of this paper is to describe the possibilities of applying geothermal energy in agriculture, with a special focus on its role in greenhouse production. In addition to the theoretical part of the paper with a description of the application of geothermal energy in various agri-food activities, an interview was conducted with the producer "Rajska rajčica" (part of the Zarja Group) from Sveta Nedelja. This company uses geothermal energy for heating in its tomato greenhouse production, where, according to the estimates of the interviewed representatives, they achieve savings of up to 80% compared to heating with various conventional energy sources.
