Abstract The development of renewable energy technologies (RET) depends on a wide range of criteria and regulations. To evaluate which RET (solar photovoltaic (PV), wind power plants (WPP), hydroelectric power plants (HPP) or bio-energy plants) have the greatest potential in Latvia, the most suitable approach is a multiple criteria decision making (MCDM). The proposed MCDM methodology involves TOPSIS model based on information entropy, which contributes as a criteria weighting tool. The study investigates seven main criteria from technical, economic, environmental and social aspects. Firstly, each alternative country is analysed due to the chosen RET criteria. Secondly, the assessment is extended, comparing specific data with Latvia’s MCDM of RET results. The research results show that, according to the best available examples of RET, hydro energy plants still play a substantial role for Latvia, the most promising RET development is based on bio-energy and wind renewable energies.

Different power generation technologies have different advantages and disadvantages. However, if compared to traditional energy sources, renewable energy sources provide a possibility to solve the climate change and economic decarbonization issues that are so relevant today. Therefore, the analysis and evaluation of renewable energy technologies has been receiving increasing attention in the politics of different countries and the scientific literature. The household sector consumes almost one third of all energy produced, thus studies on the evaluation of renewable energy production technologies in households are very important. This article reviews the scientific literature that have used multiple-criteria decision-making (MCDM) methods as a key tool to evaluate renewable energy technologies in households. The findings of the conducted research are categorized according to the objectives pursued and the criteria on which the evaluation was based are discussed. The article also provides an overview and in-depth analysis of MCDM methods and distinguishes the main advantages and disadvantages of using them to evaluate technologies in households.

Primary Energy Supply

The study analyzes the economics of renewable energy sources into electricity generation in Tanzania. Business as usual (BAU) scenario and renewable energy (RE) scenario which enforce a mandatory penetration of renewable energy sources shares into electricity generations were analyzed. The results show total investment cost for the BAU scenario is much lower as compared to RE scenario while operating and maintenance variable costs are higher in BAU scenario. Primary energy supply in BAU scenario is higher tied with less investment costs as compared to RE scenario. Furthermore, the share of renewable energy sources in BAU scenario is insignificant as compared to RE scenario due to mandatory penetration policy imposed. Analysis concludes that there are much higher investments costs in RE scenario accompanied with less operating and variable costs and lower primary energy supply. Sensitivity analysis carried out suggests that regardless of changes in investments cost of coal and CCGT power plants, the penetration of renewable energy technologies was still insignificant. Notwithstanding the weaknesses of renewable energy technologies in terms of the associated higher investments costs, an interesting result is that it is possible to meet future electricity demand based on domestic resources including renewables.

Abstract Most countries around the world are politically driven to move toward a low-carbon future by embracing renewable energy technologies for electricity generation. With abundance of renewable energy resources, Costa Rica produces over 95 percent of its electricity from hydro, geothermal, and wind power plants. Only one percent of its population live without electricity, mainly in remote territories where rural off-grid electrification is very challenging. The purpose of this research is to contribute to enhancing the opportunities to reach universal electricity access in Costa Rica by studying some cases. A comparison with the African situation is made in order to find common points of benefit and learning. This article highlights that a greater level of engagement is needed from local leaders to develop efficient solutions in Costa Rica, and brings a relevant comparison with Africa’s energy needs as well.

Given the key role of municipalities in the transformation of the energy system and observing the increased occurrence of conflicts about the construction of renewable energy plants, the author analyses conflicts relating to renewable energy plants from a sociological perspective. For this purpose, she undertakes three case studies on the construction of biogas and wind power plants, focusing in particular on the parties involved in the conflicts and their positions, perceptions, actions and potency. She shows that the conflicting parties were either in favour of the construction of the plants or advocated the preservation of the sites on which the plants were proposed to be built.

This article discusses the need for new technologies to address emerging energy and water challenges. The demand for both energy and water is expected to grow with growth in global economy and population. Therefore, there is a need to minimize future conflicts between energy and water development and to foster more reliable and sustainable use of these two very important natural resources. Several renewable energy technologies and alternative cooling approaches for thermoelectric power plants exist that could reduce water consumption for electric power generation. Improving dry, hybrid, and other alternative cooling technologies and carbon sequestration approaches could help lower future water consumption and reduce the water footprint of power plants. Likewise, research to address the issues that are limiting the implementation of low-water-use renewable energy technologies could accelerate their use, reducing both water consumption and carbon emissions. Any major scale-up of alternative transportation fuels must consider approaches that use less fresh water than current methods, and must improve water use efficiency in mining, processing, and refining future fuel resources.

Abstract A substantial part of the global energy mix depends upon fossil fuels that needed to be reduced to overcome the pollution and environment-related challenges. This has directed the world to shift the energy mix towards renewable energy technologies. Among the development in renewable energy technologies, the development of solar tower power plant is an active research topic. Over the past decade, advances in computers and simulation software systems have greatly expanded their use in design and development, which can facilitate the engineering activities of solar tower power plants. However, an important limitation is the visualization of three-dimensional geometrical design data onto two-dimensional computer screens. VR technologies are a great means in the visualization of 3D data. Therefore, this article attempts to illustrate a concept for the application of VR technologies in the development of solar tower power plant and lists down relevant support scenarios. The main focus of the paper is on analyzing the efficiency of the VR technology used in the design of solar tower power plants and learning from the experience gained in this process. A discussion about further scenarios ranging from on-site visualization of solar tower power plant infrastructure, installation and repair, cleaning and maintenance, etc. is included as well as future directions are pointed out. The demonstrator part consists of an Android Smartphone-based VR application and an HMD based VR application. Furthermore, a brief comparison of both the applications as well as of HMD and sVR is also provided.
