Investment in renewable energy sources by logistics companies has become commonplace. Organizations decide to invest in renewable energy sources not only for economic or environmental reasons, but because it is also prestigious for them. The aim of this article is to present the possible risk factors for a logistics company that uses or wants to implement renewable energy sources. This study identified individual risk factors and control mechanisms to reduce the likelihood of a particular risk factor occurring. In this article, the research methodology used is risk management through implementing a diagram of the risk-related decision-making processes of logistics companies around renewable energy sources. The analysis of the risk factors of renewable energy sources is an important element in assessing their effectiveness. By implementing the procedure of selecting an appropriate renewable energy source by logistic entities and implementing an element of risk management, there will be a significant positive impact on the optimal selection of a renewable energy source by enterprises.

Climate Crisis

In the age of the impending climate crisis, and further forecast ecological catastrophes, humankind has begun to think with growing interest about replacing existing energy sources with renewable ones. An increasing number of people have begun to discuss the need to implement registries that collect information about the energy potential of specific parts of the environment we live in. Additionally, the simultaneous registration of installations used for obtaining energy from alternative sources is desirable. In addition to quantitative attributes, such databases should also contain comprehensive spatial information. Since, in the era of globalization, the creation of such databases ought to be standardized, the purpose of this study is to indicate the directions in which the cadastre of renewable energy sources should be developed by: (i) reviewing the solutions of renewable energy sources that have been described in the scientific literature; (ii) analyzing the content of selected geoportals containing data on renewable energy sources. The literature review was preceded by a detailed bio-metric analysis, whereas the content analysis of the geoportals led to the creation of a flow chart containing a proposal for a renewable energy source cadastre, and a ranking of the analyzed portals. Nevertheless, the conceptual work was limited to the solar cadastre only.

Energy poverty is a problem that affects all member states of the European Union to a varying degree, including Poland, where about 9% of the population is at risk of energy poverty. The article aims to show the changes in energy poverty in Poland in 2010–2018. The specific goal, however, is to evaluate government measures aimed at reducing energy poverty through investments based on renewable energy sources. To present changes in the level of energy poverty in 2010–2018, the authors proposed a new synthetic measure that unifies several different measures used by researchers and allows for a comprehensive assessment of this phenomenon. The conducted research showed that in 2010–2018 there was a slow but visible decrease in the level of energy poverty in Poland. In addition, the article indicates investments in renewable energy sources that may have a positive impact on reducing the scale of energy poverty in Poland. The programs implemented with national and EU public funds, which finance investments in renewable energy sources in Poland, are also presented.

Savonius Wind Turbine

Our planet gives us many mineral sources, but they have a big disadvantage. They are finite. Non-renewable energy sources are enough only for decades, exceptionally for centuries. Current generation is aware of the importance of using other energy sources, such as sunlight, wind, rain, tides, waves and geothermal heat. These energy sources are renewable. It means that they come from sources, which are naturally replenished on a human timescale. One of these sources is wind energy. Use of this kind of energy source needs an initial investment, but it can reduce cost of running a household and other sectors. This article is about Savonius wind turbine and its use for the needs of public lighting.

The Sustainable Development

One of the main goals for sustainable development of a country is providing sustainable energy resources, which means satisfying the current needs for energy without compromising the future generations. Moreover, sustainable energy resources primarily involve greater inclusion of renewable energy sources. The biomass is the most widely used renewable energy source, mainly because of its relatively low price and its availability. However, in order for the biomass to stay a renewable energy source, it must be used rationally and with a plan, which primarily requires a detailed analysis of the current situation and resources. Therefore, the aim of this paper is to calculate the optimal utilization of biomass in energy purposes, taking into account the sustainable development of a country. As an example, in this paper Macedonia is considered. A detailed analysis of the data sources related to biomass is made and several different indicators that describe the current situation in Macedonia are presented. Furthermore, several scenarios are defined in this paper in order to calculate the optimal share of biomass in the overall energy mix in Macedonia for the next 20 years, using the MARKAL model.

Hybrid Renewable Energy

In recent days the need for energy resources is dramatically increasing world-wide. Overall 80% of the energy resource is supplied in the form of fuel based energy source and nuclear based energy source. Where fuel based energy resources are very essential in day-to-day life. Fossil fuel is also one among the energy resource and due to the high demand we face shortage in these resources. Providing electricity in rural areas is still a difficult process because of the shortage of energy resources. This issue can be rectified by choosing an alternate to electricity. To achieve this we have integrated many renewable energy sources to form a hybrid-renewable energy source system and this is capable of providing power supply to these areas. We have adopted artificial neural networks (ANN) technique based on machine learning to accomplish this process. For short-term prediction other techniques such as MLP, CNN, RNN and LSTM are used. These values are used as reference value in final execution.

Suitable Framework

Motivated by a practical problem faced by an energy trading company in Poland, we investigate the profitability of balancing intermittent generation from renewable energy sources (RES). We consider a company that buys electricity generated by a pool of wind farms and pays their owners the day-ahead system price minus a commission, then sells the actually generated volume in the day-ahead and balancing markets. We evaluate the profitability (measured by the Sharpe ratio) and market risk faced by the energy trader as a function of the commission charged and the adopted trading strategy. We show that publicly available, country-wide RES generation forecasts can be significantly improved using a relatively simple regression model and that trading on this information yields significantly higher profits for the company. Moreover, we address the issue of contract design as a key performance driver. We argue that by offering tolerance range contracts, which transfer some of the risk to wind farm owners, both parties can bilaterally agree on a suitable framework that meets individual risk appetite and profitability expectations.
