Cuba, a small island in the Caribbean Sea with a total land area of 109.884 km2 and a population of around 11.423 million, has no significant proved oil, gas and coal reserves. Also use, in a very limited manner, some of the four main renewable energy sources available in the country for electricity production, generating just 50,1 GW/h or 4,04% of the total electricity consumed in 2015 (20.288 GW/h). In 2016, electricity consumption fell to 15.182 GW/h; this means a reduction of 25% in comparison to 2015. In 2016, the participation of renewable energy sources in the energy mix of the country reached 4,65%. The different renewable energy sources available in the country are hydropower, wind power, solar photovoltaic, and bioenergy. In 2015, out of Cuba’s total 566 MW of renewable energy capacity installed, 83% of the total was in the bioenergy sector. In 2016, the renewable energy capacity installed in the country reached 642 MW. According to the decision adopted by the Cuban government, the participation of renewable energy sources in the energy mix of the country should reach 24% in 2030, an increase of almost 20% compared to the level reported in 2016. Among the different renewable energy sources available in the country, solar energy is one of the main contributors to the national energy system, and also one of the leading supplier of energy to independent users all over the country.

Design Study

Design study of a synergetic system among small long life gas cooled fast reactors and renewable energy has been performed. A pump storage system is the center in the integration among considered energy sources. Using this system many renewable energy sources and the small nuclear power plant can be integrated to produce reliable energy sources which can be used for electricity production, desalination, etc. In this system each energy source can store energy by contributing pumping water from a low level reservoir to a high level reservoir. The nuclear power plant module must satisfy inherent safety requirement, and have flexibility in producing electricity, clean water (through desalination), etc. The reactor can be operated for 25 years without the necessity to refuel during that period. To achieve inherent safety capability it is important to minimized excess reactivity during burn-up to be below delayed neutron fraction value so that super prompt critical accident such as in Chernobyl accident case can be avoided. Here minimization of excess reactivity is carried out by adjusting core and blanket region width and plutonium enrichment in core regions.

Abstract Examining willingness-to-pay (WTP) for renewable energy sources (RES) as well as views on energy topics can enable policymakers to design effective measures for facilitating the transition from fossil fuels to a renewable-based energy system. The aim of this study was to investigate environmental students’ willingness-to-pay for renewables and their views on various energy topics. Results showed that respondents preferred renewable-based electricity production to conventional energy production while solar energy emerged as the most preferred renewable type. In addition, most respondents were willing to pay for renewable energy but would pay relatively low sums of money per month. Moreover, respondents were divided over whether new lignite plants should be constructed in Greece. Finally, social media and special websites were the most favored media of daily information.

The article provides an overview of the current state of energy in the world and in Russia, which focuses on the development of renewable energy sources (RES). An analysis is made of the trend in the production and consumption of energy resources, as well as an assessment of the use of renewable energy in Russia. Incentives for the development of renewable energy sources with the characteristics available in the world are determined. Conclusions are drawn about the importance of developing this industry both in Russia and in the Chechen Republic, as one of its regions. An assessment is given of the development of wind and solar energy in Russia. The current power supply structure of the Chechen Republic is considered, where the indicators of maximum electric power, consumed electric power, and also electric power generation of the republic are given. The analysis of the possibility of using wind and solar energy resources, as well as small hydropower of the Chechen Republic. Options for the development and effective use of renewable energy sources are considered, taking into account the fact that the use of energy resources based on modern innovative technologies, the introduction of new promising alternative sources, and the search for ways to stimulate the use of renewable energy sources, where it is supposed to organize and introduce a tariff policy, is one of the main tasks of energy development which give a complete systemic idea of the scale of the problem of transferring the energy system to innovative rails. Some options are proposed for the most expedient development of the energy system of the Chechen Republic, the construction of small pilot plants using renewable energy sources, with the goal of actual (experimental) confirmation of the predicted calculated values, as well as the gradual mass introduction of plants using renewable energy sources in the private sector with the creation of the necessary tariff conditions for use and construction installations on an industrial scale within the framework of energy private or public companies. Priority tasks have been set for the prospective development of the republic’s energy sector by introducing renewable energy sources.

Growing Economy

India’s energy needs are in demand with the increase in energy and other electric uses which is highest among the world. There are sectors which heavily rely on energy generated by fossil fuels but there is also seen a paradigm shift towards renewable energy sources. If India continues to rely on the former then they end up blocking development in energy system meeting uncertainties and face difficulties in supply of fossil fuels. To meet the fast-growing economy, India needs to supply the energy 3-4 times more of what they are supplying now. Government of India has become aware of the situation and has started facilitating polices in action towards a sustainable energy. As of 2019, India’s on grid renewable energy capacity is 85.9 GW. Government is working to establish 500 GW of renewable energy source by 2030.

Positive Effects

In this article, we aim to identify the determinants that profoundly impact renewable energy sources development in Poland. To this end, the authors have conducted qualitative and quantitative analyses of Poland’s renewable energy sector. In this paper, we demonstrate an original approach considering the different development levels of the given sector across provinces (voivodeships). It uses panel data from the Local Data Bank of the Statistics Poland on electricity production from renewable energy sources in individual voivodeships in Poland from 2005 through 2019. The study confronts the results of previous studies and sheds light on the situation in Poland—specifically, upon the changes that have happened over the ten years (2010–2019). The qualitative analysis shows a negative correlation between energy consumption and the share of renewable energy sources in total energy production. Evidence shows that favorable changes are underway in the energy production structure: RES share is growing and by degrees satisfying energy demand, and there is growing potential of energy entities in Poland. Furthermore, the analysis shows that R&D and total expenditures on environmental protection and water management investments do not significantly affect the development of RES. A dynamic panel data model has been used to analyze the group and time effects on the dependent variable. The findings confirm the existence of the persistency effect and indicate positive effects of total installed electric capacity (IEC) and household electricity consumption (HEC). Nonhousehold electricity consumption (NHEC) has a negative effect on the endogenous variable, i.e., the renewable energy sources share in the gross final energy consumption (RESS). The research results may be applicable as recommendations for energy efficiency policy development based on renewable energy sources depending on the RES development level in the regions of Poland.

The Impact

Abstract BackgroundThe characteristic feature of modern energy sector in the EU is the development of environmentally friendly technologies based on renewable energy sources (RES). The use of alternative and RES contributes to resolving not only energy efficiency issues, but many of the environmental, economic and social problems. RES are also one of the priorities of the world's low carbon policy and reducing CO2 emissions into the atmosphere. Growing electrical energy consumption and increasing integration of RES in power systems have led to new challenges, thus it is required to investigate and properly analyze the impact of integrated RES on the power system as a substitute for fossil fuel resources.ResultsThe aim of the article is to show the possibilities of developing RES in Poland in the context of environmental protection, energy self-sufficiency and international obligations. The depletion of primary energy sources and the increase in emissions of greenhouse gases to the atmosphere forces undertaking certain activities, aimed at seeking substitutes for fossil fuels. According to the author’s analysis, RES are the best and safest substitutes for traditional energy resources such as fossil fuel.ConclusionsThe author examines electricity production mix in EU counties and compares it to Polish energy sector. Taking into consideration the transmission network density in Poland, while energy sector changes its structure and expands, the mix of technologies deployed to produce electricity determines the associated burden on transmission networks. Polish energy sector development in the context of modernization of transmission grid provides an opportunity for investors to prepare the energy system for increasing the share of renewable energy sources. In the process of implementing the appropriate solution, the experiences of other countries that have significantly increased the share of renewable energy in the past could be used. This article presents the main areas of action that may facilitate the further integration of different energy sources in the specific context of Poland's changing energy system. Not all integration options will be important for Poland at the same time.
