Bioeconomy in the European Union was considered a long-term vision leading to increased competitiveness, better use of resources and reduction of carbon footprint already since 2005. Bioeconomy remains one of the key strategies by European countries in the immediate as well as more distant future. The European Commission developed the guidelines, which were followed by instruments enabling the implementation of action plans and strategies. In some European countries, among them Germany and the Netherland as the leading ones, such systems are already deeply rooted in their economic reforms. This includes circular economy, use of biomass, principle of added value cascade and biorefineries. There are opportunities in the field of the processing industry, different fields of biomass production and processing such as agriculture, aquaculture, forestry, food and wood processing, as well as general biobased industry. The aim of this research was to assess the bioeconomy opportunities and factors influencing bioeconomy. Our study was conducted by in-depth semi-structured interviews with several shareholders from industry, research institutions, policy makers and clusters in Slovenia. Surprisingly, we have observed, that in Slovenia, there is practically no strategy focusing on the transition towards bioeconomy, but only few short-term examples of good practice in this field. Although a number of research projects have been conducted in this sector, and considering very low availability of investments in this field, an underdeveloped market and low awareness-level, there are only few biobased products avaiable on the Slovene market. The potential of clustering has thus become been underexploited. Leta 2005 se je v Evropski uniji govorilo o biogospodarstvu kot dolgoročni viziji, ki bo omogočila dvig konkurenčnosti, boljše izkoriščanje virov in zmanjšanje ogljičnega odtisa. Biogospodarstvo bo ena izmed ključnih usmeritev evropskih držav v bližnji in daljni prihodnosti. Smernice razvoja je začrtala tudi Evropska komisija, temu pa sledijo podporni inštrumenti, ki omogočajo vpeljavo akcijskih načrtov in strategij. Nekatere evropske države, med njimi vodilna Nemčija in Nizozemska, imajo tovrstni sistem že močno zakoreninjen v gospodarskih reformah, vse od krožnega gospodarstva, uporabe biomase, principa kaskade dodajanja vrednosti in vpeljave biorafinerij za nove produkte. Priložnosti so tako na vseh področjih, od kmetijstva, lesne in lesnopredelovalne industrije do ribištva in bioosnovane industrije. Namen raziskovalne naloge je bil preveriti dejavnike, ki vplivajo na razvoj biogospodarstva v Sloveniji. Raziskavo sem izvedel s poglobljenimi polstrukturiranimi intervjuji z več predstavniki iz industrije in raziskovalnih ustanov ter s kreatorji politik (državnih ustanov) in grozdov. Izkazalo se je, da v slovenskem prostoru nimamo strategije, namenjene prehodu v biogospodarstvo, in tako prihaja zgolj do kratkotrajnih primerov dobrih praks na tem področju. Zaradi nizkih industrijskih vlaganj, nerazvitega trga in nizke stopnje ozaveščenosti, tovrstnih produktov tudi še ni na tržišču kljub mnogim raziskavam, ki potekajo na tem področju. Potencial grozdenja pa ostaja neizkoriščen.

The Master’s thesis analyzes energy consumption of WiFi modules, which serve to connect devices pertaining to the Internet of Things with the internet. In the context of the thesis, I have reviewed over 200 WiFi modules online and reduced the number of modules to 28 according to certain criteria outlined beforehand. Of the remaining 28 WiFi modules, I selected 4 that I have thoroughly examined and used for various measurements. For measurement purposes, I connected the modules with a test environment via an SPI interface and implemented the necessary software drivers on the microcontroller with ARM architecture. To measure energy consumption, I used a digital flow meter with a sampling frequency up to 20 kHz and an accuracy of the 300 μA order, for which I implemented a library in the Python programming language. I concentrated on the energy consumption using WPA2 encryption, since data security is always of utmost importance. The results of the measurements have shown that despite having comparable specifications, WiFi modules differ greatly between different manufacturers in terms of actual energy consumption. Additionally, the complexity of controlling WiFi modules also varies from manufacturer to manufacturer, which affects costs and development time. Magistrska naloga obravnava problematiko energijske porabe modulov WiFi, ki služijo za povezavo z internetom pri napravah interneta stvari. V sklopu naloge sem preko spleta pregledal preko 200 modulov WiFi, nato sem seznam po v naprej določenih grobih kriterijih skrčil na 28 modulov. Od preostalih 28 modulov WiFi sem izbral 4, ki sem jih nato temeljito preučil ter uporabil v meritvah. Za potrebe meritev sem module priklopil na testno okolje preko vmesnika SPI in implementiral potrebne programske gonilnike na mikro krmilniku z arhitekturo ARM. Za meritev porabe sem uporabil digitalni tokovni merilnik s frekvenco vzorčenja do 20 kHz in natančnostjo reda 300 μA, za katerega sem implementiral knjižnico v skriptnem jeziku python. Osredotočil sem se na porabo energije pri uporabi enkripcije WPA2, ker je varnost podatkov vedno zahtevana. Rezultati meritve so pokazali, da se kljub primerljivim specifikacijam porabe modulov WiFi med različnimi proizvajalci, dejanska poraba energije zelo razlikuje. Poleg tega pa se od proizvajalca do proizvajalca razlikuje tudi zapletenost krmiljenja modulov WiFi, kar vpliva na stroške in čas razvoja.
