Green Business - A Business of Sustainability
Žan Kokalj, 2016, diplomsko delo/naloga

Opis: Sustainability practices and sustainable development have been in close relation with human beings for a long time. This thesis aims to present historical aspects of sustainable development throughout the time, along with numerous green business ideas and green organizations presentations. From hunter-gatherers to ancient civilizations to fossil fuel era, historical review consists of connections between people from different times and places. Whilst moving from history to the present, the thesis offers insight in terms of green and sustainability-related definitions that help in understanding the idea behind terms such as green businesses, sustainable development, eco-innovations, green products, green consumer, green marketing, greenwashing, green certification, and carbon offsets and carbon credits. For better understanding of the related theoretical approaches, the thesis also offers a wide range of green business ideas such as green building and urban planning, sustainable agriculture, renewable energy sourcing, sustainable forestry, green transportation, green hair salon, green gym, green wedding planning, green cleaning services, recycling and waste management, and sustainable brewing. The benefits, issues and risks that green businesses are dealing with are also described. Green practices nowadays are represented by many individuals and organizations, of which some are also included in the research part of this thesis. 32 organizations have been interviewed and provided valuable data that was used in creating a brand new sustainability model, called ‘Path to sustainability’, which aims to connect vital sustainability fragments together in a wholesome system, along with connections between related fragments. Besides the model, the thesis also provides an overview of issues and restrictions that oppose sustainable development.

Biogas as a renewable energy source
Matjaž Ošlaj, Bogomir Muršec, 2010, pregledni znanstveni članek

Opis: Renewable energy technology does not simply produce energy, heat and transport fuel, but also offers the opportunity to live in the footsteps of a reasonable future development. In Europe and other industrialized regions, the main reason for the development of renewable energy is the environment, in particular the concern in relation to global climate change and the need to improve security and diversity of energy supply. In the developing countries, they promise a new hope for renewable primary energy supply in regions without conventional energy and provide an opportunity for sustainable development. Productionof "green energy" from biogas, which is among the renewable energy sources, promises an environmentally less damaging way of obtaining energy by reducing CO emissions into the environment and reduces energy dependence on imported energy sources. Biogas production is of major importance for the sustainable use of agrarian biomass as renewable energy source.

Renewable energy sources in Slovenia: Determining possible development trends until 2020 by using linear forecast and simulation with geometric Brownian motion process
Dejan Tasić, 2017, diplomsko delo

Opis: Renewable energy sources in the European Union and the Republic of Slovenia present an increasing share of energy each year. This thesis contains the data from Eurostat, where the statistics of renewable sources in the European Union and the Republic of Slovenia are analyzed from 2004 to 2014. On the basis of this data, the linear forecast and simulation by using process of geometric Brownian motion are conducted for the Republic of Slovenia for the time period 2015-2020. The goal is to determine if the Republic of Slovenia will achieve target objectives of European directive for renewable energy sources until 2020.

Practicality of base load renewable generation in India
Karthik Subramanya Bhat, Udo Bachhiesl, objavljeni znanstveni prispevek na konferenci

Opis: India, among several other countries globally, now faces a unique situation where managing the energy transition process without hurting the economic development becomes the highlight of its policies. The Indian power sector is highly carbon intensive, with coal based power providing 70% of the total electricity generated. Renewable energy occupies around 15% of the capacity mix. Energy access along with several other challenges, pose an obstacle to the needed transition to clean energy. As the seasonal load variations in India are not prominent, cheap coal based power supplies most of the load profile,while gas power plants are used for peak loads. The myth that renewable energy sources cannot meet baseload demand has become widely accepted and wide-spread, given their fluctuating nature. Several studies demonstrate an optimistic transition to 100% renewable sources might just be possible in the coming decades. In a carbon-rich power sector like India, the ‘base load’ mind set is a pretty big and powerful hurdle, as ensuring base load generation becomes a major issue with implications directly affecting the country’s economy. In this study, an effort has been made to discuss whether base load renewable generation in India is feasible, and the challenges involved.

Economic effects of renewable energy technologies
Dario Maradin, Ljerka Cerović, Trina Mjeda, 2017, izvirni znanstveni članek

Opis: Rapid economic development has resulted in the more frequent use of renewable energy technologies. On the other hand, the production and use of renewables fosters the development of new technologies, creating many new opportunities for entrepreneurial-minded individuals and, consequently, the economy in general. Renewable energy technologies have a multiplier effect in spurring the economy and the development of not only the energy sector but also all the supporting activities related to such industry. The purpose of this research is to analyse both the positive and the negative economic effects of investing in various renewable technologies, as well as to confirm, by means of the energy-economy model, the benefit of such technologies in boosting the economy.
Ključne besede: renewable energy sources, new technologies, boosting the economy

Public support of solar electricity and its impact on households - prosumers
Jarmila Zimmermannová, Adam Pawliczek, Petr Čermák, 2018, izvirni znanstveni članek

Opis: Background and Purpose: Currently, the idea of households - prosumers is broadly discussed in public governments, mainly in connection with both the energy security issues and the environmental issues. Therefore, the main goal of this paper is to present new agent model of household - prosumer and to compare two scenarios – “off grid household” and “on grid household”. The additional goal is to evaluate the impact of public support of solar electricity on the economic efficiency of household – prosumer projects (systems). Design/Methodology/Approach: The model is structured as a micro-level agent model, representing one household – prosumer. The model has the following general characteristics: one household with own electricity generation (photovoltaic panels), battery and in case of “on grid household” also connection to the grid. The main goal of the agent is to cover electricity consumption in household with minimal costs. The agent model of prosumer is tested and validated, using the empirical data. Results: The highest level of subsidy has significant impact on the economic indicators of selected scenarios. It causes lower investment costs at the beginning of the project and consequently shorter payback period (3-4 years earlier), positive cumulative cash flow, net present value and IRR in earlier period (approximately 5-10 years earlier, depending on the scenario). Conclusion: We can recommend to the government to continue with current system of subsidies, since it contributes to better economic indicators of particular solar electricity projects. On the other hand, the level of subsidy should be at least the same as in current year 2017, for the purposes of representing the significant part of the investment costs. Low level of subsidy has negligible impact on the economic indicators of households – prosumers projects. The developed agent model is suitable for the evaluation of economic impact of public support on households – prosumers.
