Full textAbstract:
Greening the economy requires green innovations, and innovations require investments. Most countries of the world are still relying on conventional (fossil-based) sources of energy. The transition toward green or renewable energy sources is an effective and innovative way to meet ever-increasing demand as a result of the rising population. Another reason for innovations in the field of green energy is the need to mitigate climate change and avoid pollution, especially in developing countries. The monitored investments into renewable energy sources are usually public. Therefore, this paper aims to determine whether the selected countries of the world produced renewable energy efficiently, considering the investments made by public financial institutions and installed electricity capacity for renewable energy sources, for the period 2013–2017 (for a deeper analysis, the year 2017 was chosen). For this purpose, the Stochastic Frontier Analysis model in the logarithmic form of the Cobb-Douglas production function is used, which helps to judge the competitiveness of countries based on effectively transforming the inputs into outputs. Results suggest that the effect of the first variable “installed electricity capacity” on electricity generation was highly statistically significant, and the impact of the second variable “public investments” was characterized as statistically insignificant. The monitored countries were divided into 10 groups according to the different range of estimated output-oriented technical efficiency from 0.00 to 1.00. Most countries should increase the renewable electricity generation approximately by 40-49%, given the level of inputs (16 countries of 6th group with estimated output-oriented technical efficiency 0.51-0.60) for the year 2017.

Full textAbstract:
We assess how renewable electricity production interacts with GDP per capita to influence CO2 emissions per capita, analyzing cross-national data from 1960 to 2012. We find an interaction effect between the quantity of renewables and GDP per capita, where, counterintuitively, economic growth is more closely tied to emissions in nations with a large share of their electricity from renewable sources and growth of renewable electricity has a smaller suppressive effect on emissions in more affluent nations. Additional analyses suggest that this relationship emerges because renewable energy sources tend to suppress nuclear energy in affluent nations, thereby unintentionally perpetuating reliance on fossil fuels.

Full textAbstract:
AbstractNigeria faces a perennial problem of inadequate electricity generation and supply. Electricity generation from fossil fuel sources has not succeeded in meeting the electricity needs of the country. And attempts to diversify electricity generation sources to include renewable energy sources have not been successful. Although there is a policy direction supporting the inclusion of renewable energy sources for electricity generation, the Electric Power Sector Reform Act 2005 (ESPR) has not succeeded in achieving the country's sustainable electricity drive. Nigeria needs to vigorously pursue its renewable electricity objectives through a law dedicated to encouraging uptake of renewable energy. This article examines the law and the policies underpinning Nigeria's sustainable electricity drive through a critique of the EPSR Act and the energy policy in light of Nigeria's renewable electricity objectives.

The main objective of the paper is to estimate the dynamics of basic categories concerning the exploitation of renewable energy sources for electric energy production in Poland. For the realization of this objective time series were used, in which capacities of electric plants based on renewable energy sources were described both globally and in fractions composing from water energy, energy obtained from solid bio-fuel, energy obtained from bio-gas and solar energy. The research was carried on with the usage of exponential trends. A separate problem is to determine changes of partition of energy obtained from renewable energy sources in relation to the total utilization of electric energy. The investigation shows that in this case the exponential trend fits quite well. The comparison were also made between the average rate of increase of particular renewable energy sources carriers in creation of electric energy in Poland.

The aim of this paper is to present the state of development of renewable energy sources (RES) in Poland in accordance with the obligations of European Union energy policy. The EU Member States are obliged to adopt different support mechanisms for the development of renewable energy sources, and in consequence to achieve their Directive’s targets. Poland, being a Member State of the EU since 2004, has accepted a target of a 15% share of energy generated from renewable energy sources in final energy consumption, including 19.3% from renewable electricity until 2020. Due to the difficulties with target achievement, the authors found it reasonable to analyze the challenge of RES development in Poland. The article presents energy policy in the EU, as well as the review of measures implemented for renewable energy development. The current state of and perspectives on using renewable energy sources in Poland and in the EU are also depicted. In the article, the authors analyze the relation between reference prices at dedicated RES auctions in Poland and the levelized cost of electricity (LCOE). The paper also provides a description of the renewable energy sources’ development in three areas: electricity, heat and transport biofuels. Its main content, though, refers to the generation of electricity from renewable energy sources.

AbstractThe intensive development of renewable energy, especially solar power and wind power plants, poses risks of disrupting the balance reliability of the grid. There is the need to develop electricity storage system area, first of all, due to the global tendency to increase the demand for electricity and the number of electricity generation from renewable sources. The issue of guaranteeing electricity supply to the consumer operating in the autonomous renewable source – energy storage device – consumer system is the main criterion when selecting the installed capacity of the generator on the basis of renewable sources and energy storage device capacity. Also, the application does not allow reducing voltage fluctuations in the renewable sources – the consumer system.

Full textAbstract:
Globally, the continuous increase of energy consumption coupled with the depletion of the limited fossil fuel sources and their negative impacts on the environment, has shifted focus towards renewables for a sustainable development. For the last fifteen years, the world has enjoyed renewables generation capacity increases in a double-digit Terawatt-hours range. Although renewables consumption is fast developing in Asia Pacific, Europe and North America, significant coordination efforts are required among stakeholders in sub-Saharan Africans countries such as Cameroon. In 2018, the total final energy consumption in Cameroon was 7.41 Mtoe, 74.22% of which was from biomass, 18.48% from fossil fuels and 7.30% from electricity. Furthermore, 6977 GWh of electricity was produced, 78.29% of which from the major electricity operator (ENEO S.A. Cameroon) and 21.71% from independent producers (GLOBELEQ, ALTAAQA Sinohydro China and AGGREKO). More than three quarter of electricity produced were consumed by industry (57.04%) and residential (20.74%) sectors. The country's installed electricity generation capacity rose to 1402 MW, 56.15% of which was from hydropower, 43.84% from fossil fuels (17.55% from natural gas and 26.29% from oil) and 0.01% from solar photovoltaic. The promotion of renewable energy is an important part of Cameroon's plan to increase energy security and provide job opportunities to the country. Yet, the lack of proactive and long-term renewable energy policy and laws, in addition to less attention paid to renewable energy training and research, financing mechanisms, and unaffordable costs of renewable energy technologies to the poor population are amongst present issues hindering the development of renewable energy in the country. Hence, this paper aims to highlight the present status of renewable energy exploitation and development in Cameroon.

The world energy crisis from non-renewable fossil energy sources greatly impacts the electricity sector. Meanwhile energy is needed to ensure food security is estimated at 38 percent of the energy consumed in the food system. Agrifood systems require renewable energy, access to modern energy services in rural areas, technology related to climate-smart agriculture. Hybrid technology makes it possible, we combine several new and renewable energy sources to save electricity more effectively and efficiently. Able to manage the shifting period of any renewable energy source in hybrid energy by the control system. In this case, each of these new renewable energies can be arranged based on their respective existence. With the existence of a power plant with renewable energy in the form of hybrid energy, it can also facilitate farmers in terms of electricity sources because in the most recent agriculture there is no electricity installed. With this method farmers can process the natural products they have easily, and are cost-effective.

Full textAbstract:
The existence and continuity of life on Earth is based on the existence of an ecological balance. Under the influence of pollution, the quality of the natural environment gradually degrades. Thus, pressures are exerted on the environment, including from energy production and consumption activities. The different phenomena of pollution, associated with the destruction of the environment, have made the sources of energy production diversified. Sustainable development can be achieved through the use of technologies that protect the environment. Within the electricity sector, energy from renewable sources has grown significantly in recent years. Energy production from Renewable energy reduces the use of fossil fuels, but also influences the process of reducing greenhouse gases. The article starts from the analysis of the current situation of renewable sources in the member countries of the European Union. With support of the comparative analysis of existing data at European level, the stage of achieving the European Union's objectives on renewable energy is presented. Also, comparative analyses of data on the share of renewable energy in final energy consumption are presented. Lack of emissions of pollutants, and the fact that they are inexhaustible, make, on the whole of electricity production, the share of renewable sources increases.

Full textAbstract:
In order to achieve the objectives set by the Sustainable Development Goals and the Paris agreement, the legislative framework that is developed at the national and regional level must be appropriate. Research has focused on the importance of environmental policies to stimulate renewable energy demand and has also highlighted the existence of legal regimes more inclined to preserve the current model of dependence on fossil fuels. The main aim of this paper is to observe the impact of different regulation framework in the use of renewable energies in electricity generation. The choice of Spain and Cuba was based on several reasons: first, they present different models of legal regulations for renewable energies, with more centralized power in the case of Cuba and more influence of supranational institutions in the case of Spain; second, they have similarities regarding their productive model (highly dependent on hydrocarbons as sources of electricity generation) and the high potential for electricity generation with renewable energies thanks to their rich natural endowment that could favor energy generation from sources like the sun, wind and water; finally, both countries face a global situation where they could take advantage of this cost-cutting moment, and therefore, of electricity tariffs, to propose a sustainable model of electricity generation based exclusively on renewable energies. The conclusions show that Spain can become a role model to improve the Cuban system, given that the European and Spanish “green” positions can be very useful in developing Cuba’s future energy model based on renewables. The existing ties between the Caribbean country, Spain and the European Union (EU) should be the basis to support a model for which Cuba has an outstanding endowment of natural resources and where the similarities with Spain can generate synergies based on the European experience.

As the proportion of renewable energy in the electricity system increases, a new suite of barriers becomes apparent. These include the unsuitability of traditional network configurations for often remote renewable resources, and the need to develop a diverse range of renewable-energy sources to ensure electricity system stability and security. Substantial legal reform will be necessary to develop an electricity system that can accommodate high volumes of renewable energy. This paper analyses recent legal reforms for renewable energy in the United Kingdom and Germany to illuminate a regulatory shift away from single-plant support to whole-of-system approaches to electricity system development. Regulatory attention has shifted to reform regulatory frameworks for electricity networks to be more accommodating of renewable energy, rather than simply providing financial support for renewable sources. These changes have been supported by a high-level commitment to develop an electricity system that is both efficient and sustainable.

Full textAbstract:
The energy sector reform in the Republic of Croatia (started 2001), which comprises restructuring, liberalization, privatization, and changes in the overall energy sector, has a significant effect on the possibilities of introducing and increasing the share of renewable energy sources (RES). The adoption of a new legislative framework within the context of reforming Croatia?s energy sector is of key importance for further development and for the future or RES utilization. The Electricity Market Act sets out the le- gal obligation to purchase electricity produced from RES in the manner that a quota or a minimum obligatory share of RES in electricity production is determined by a Government ordinance combined with Tariff system for the production of electricity from renewable energy sources and co-generation. Consequently, on the one hand, incentive funds needed to cover increased costs of production from RES will be collected from customers through the supplier and distributed to privileged producers (feed-in-tariffs, purchase is guaranteed to RES producers on known terms) through the Market Opera- tor. On the other hand, RES investment projects will be encouraged by pur- pose-specific government subsidy and by the Environmental Protection and Energy Efficiency Fund (out of public budget). By applying new energy legislation and associated by-laws (coming into force in 2007), RES projects in Croatia will be provided with a complete and stable legal framework as well as support through incentive measures which will equitably value environmental, social and other benefits of RES use.

Full textAbstract:
AbstractThe article analyses whether electricity production from renewable energy sources can be the object of a public service obligation. This question is of particular importance for the State aid assessment of payments to producers of electricity from renewable energy sources. Such payments typically occur under so-called feed-in tariffs, which are a regulatory mechanism used in most Member States to promote the production of electricity from renewable energy sources. The author argues that there are compelling reasons for considering that Member States can introduce public service obligations with respect to the production of electricity from renewable energy sources, and that compensation payments granted are exempted from the notification obligation under Article 88(3) EC treaty, if the beneficiary undertaking receives not more then 30 million EUR per year as compensation, and if its turnover does not exceed 100 million EUR. Should these thresholds be exceeded, the compensation payments need to be notified to the Commission. The Commission will then assess them under the Community framework for public service compensations, which has been adopted in November 2005.

Purpose This paper aims to identify and introduce areas in Kerman with a very high potential for produce energy from renewable energy. In this paper, with studying renewable energy resources of the world and Iran, and with the introduction of renewable energy resources in Kerman Province and its counties as a proper supplier of energy in Iran and regions. At the end of this discussion, it is seen that the positive impact of clean energies on the economy, the environment and the health of the region and the country and the potential of the Kerman Province in this rare energy place are considered well. Design methodology/approach To study the energy consumption in Iran and based on universal reports, this area is the largest renewable energy production region in Iran. Findings Currently, electricity used in Kerman is nearly 2,000 MW, while the capacity of production is 1,500 MW which is almost the share of renewable energy in electricity production rate is zero. With regard to industrial development plans in Kerman Province, 5,000 MW of electricity will be needed in the near future, so the province will face an energy crisis. Iran is also a developing country and economy; agriculture and the production of this country is extremely dependent on energy and electricity, and it seems that using renewable energy sources is a way to prevent an energy crisis in the country. Originality/value This paper introduces the Kerman Province and examines the potential of this province as a massive source of energy in Iran and the world. Specific qualifications of this region include the climate variability, existing water dams, suitable areas for utilization of biomass and the high potential that this area has for the development of geothermal energy. These qualifications all contribute to make this region a hub for great production of energy from renewable energy sources in Iran.

Currently, the dominant energy source for electricity generation in the Arctic is diesel, which is well proven for Arctic conditions. However, diesel is expensive in the Arctic, often due to long and complicated fuel transportation routes, and so inhabitants of Arctic communities can face high electricity costs. This paper investigates whether renewable energy resources can be harvested in a feasible and cost-competitive manner. The paper highlights which renewable energy resources are generally available in the Arctic and analyzes how renewable resources, such as hydropower, wind, and photovoltaics, can be used. Furthermore, we present three specific case studies to provide in-depth insight. A simulation with different energy generation scenarios using different renewable energy sources and penetration levels was performed for each case. The results indicate that renewables can be a cost-competitive option and that the optimal mix of renewables varies for different communities. Stakeholders and experts from the case study communities were also interviewed and their responses indicated a general acceptance of renewables.

The utilization of conventional sources of energy releases harmful pollutants to the environment causing global warming and acid rain. For that reason, it becomes necessary to use a non-depletable, sustainable and eco-friendly renewable energy as a mean of producing electricity. Malaysia is tropical country rich in resources beneficial in electricity generation as it is in equatorial region therefore it has an abundance of solar irradiance of average annually. In addition, Malaysia’s demand in electricity is increasing to 124,677 GWh by 2020. Therefore, the electricity generation from renewable sources in Malaysia is anticipated to grow in the future alongside the government endorsement due to its clean, eco-friendly and free source of energy which can highly reduce the dependency on oil and gas that emits harmful pollutants to the environment. This paper gives a comprehensive review on the renewable projects and researches in Malaysia, challenges that affect popularity of renewable energy in Malaysia and available and successful renewable energy system in Malaysia.

This article reviews that flow batteries can turn intermittent wind power from a utility manager’s burden to a green and reliable energy source. Customers and the popular press have made it exceedingly clear that they expect wind, solar, and other renewable energy sources to play an increasingly important role in generating the electricity that powers modern society. This desire is often driven by concerns about air quality, public health, and energy security, among other factors. For a utility planner, any intermittent source is not dispatchable. A dispatchable energy source can be scheduled for use at the planner’s convenience. Among renewable energy sources, hydroelectric and geothermal facilities are also dispatchable, within the natural limits of the resource availability.

The study presents assessment of the production of electricity obtained from renewable sources in selected European Union countries in 2010 and 2016. Among selected countries, the largest amount of electricity from renewable sources in 2010 was produced in Germany – 9,546.56 ktoe and in 2016 – 16,409.73 ktoe. In the analyzed countries of the European Union there was an increase in the production of energy obtained from renewable sources in comparison to 2010 and the dynamics of this growth in selected countries ranged from 106.1% to 217.0%. On the basis of the cluster analysis, it was found that Poland was in a similar group as Hungary in obtaining energy from renewable sources. On the other hand, Austria stood out the most from the surveyed countries, which proves that there is a big difference resulting from the energy management there in the area of obtaining electricity from renewable sources. Based on the principal component analysis, it was found that among selected EU countries, Austria is the most focused on the production of electricity from renewable sources from solid biofuels and water. Germany obtains the largest amounts from the sun, other renewable sources and wind.

Global GHG (greenhouse gas) emissions are increasing substantially and electricity sector is one of the key contributors to the world’s total GHG emissions. GHG emissions cause ozone layer depletion and global warming. Different policy regulation agencies are adopting regulations to reduce GHG emissions in various sectors. People already have started power generation from cleaner sources. Renewable energy sources can provide cleaner electricity. Bangladesh is a densely populated country and most of the country’s electricity is produced from natural gas and coal. The Bangladesh government has set a goal to utilize renewable energy for the production of 10% of its electricity by the year 2020. Bangladesh has a lot of isolated coastal areas which are not connected to the national grid which can be electrified by using abundant wind energy. In this study a techno-economic analysis has been conducted for an off-grid island of Bangladesh. The analysis was conducted by developing a data intensive model that calculates the generation cost of electricity from wind energy. The model also estimates the capital cost of the system. The model shows that electricity can be produced from wind energy at a cost of $0.57/kWh. The system’s capital cost was calculated to be $63,550.16.Article History: Received October 15th 2016; Received in revised form January 26th 2017; Accepted February 4th 2017; Available onlineHow to Cite This Article: Rahman, M.M., Baky, M.A.H, and Islam, A.K.M.S.

Full textAbstract:
Information on public support and willingness to pay (WTP) for renewable energy from alternative sources is critically important for the development and evaluation of renewable energy policies and programs. This study assesses consumer support and WTP for electricity from solar panels, wind turbines, and on-farm anaerobic digester systems (ADS) in the United States, using data collected from a household survey in the state of Vermont. Empirical results suggest that solar power was the respondents’ top choice for public investment, and cow power (electricity generated from ADS) was the least-favored choice. Also, the variations in the likelihood of being willing to pay a premium for each renewable electricity across respondents were closely associated with factors such as education, political affiliation, homeownership, and local agricultural engagement. The relatively low level of public support and WTP for cow power is likely the result of unfamiliarity with this renewable source of electricity, and more educational efforts are highly needed to promote this renewable energy with many environmental benefits for a dairy state.

Full textAbstract:
With the rapid development of the emerging technologies and significant cost reduction of the deployment for solar energy and wind power, the replacement of traditional power generation by renewable energy becomes feasible in the future. However, different from currently deployed centralized power sources, renewables are categorized as one kind of intermittent energy sources, and the scale of renewables is small and scattered. In the recent literature, the architecture of virtual power plant was proposed to replace the current smart grid in the future. However, the energy sharing concept and the uncertainties of intermittent energy sources will cause the short-term energy management for the virtual power plant much more complicated than the current centralized control energy management for traditional power generation system. We thus propose a hierarchical day-ahead power scheduling system for virtual power plant in this work to tackle the complex short-term energy management problems. We first collect electricity consumption data from smart appliances used in households and predict power-generating capacity of renewable energy sources at the prosumer level. Then, the proposed hierarchical power scheduling system is employed to schedule the usage of electricity for the customers by considering the efficiency of the use of distributed renewables. Notably, charging management of a moving electric vehicle is also considered in the proposed power scheduling mechanism. In addition, a real-time power tracking mechanism is presented to deal with the forecast errors of volatile renewable power generation, electricity load, and moving electric vehicle charging, and the maximal usage of renewables and reduction of the burden on community virtual power plants during time period of peak load can be achieved accordingly. The experimental results show that the proposed day-ahead power scheduling system can mitigate the dependency on traditional power generation effectively, and balance peak and off-peak period load of electricity market.

Problems and Perspectives in Management 17, no. 3 (September 30, 2019): 464–76. http://dx.doi.org/10.21511/ppm.17(3).2019.37.
Full textAbstract:
This paper elaborates on the theoretical and methodological fundamentals of a tradable green certificates system to foster renewable energy development in Ukraine. It proposes a management mechanism premised on the classical market model of tradable green certificates aiming at increasing the share of electricity from renewable energy sources in the country’s energy mix. Organizational stages of the mechanism formation at the national level and a methodological approach to assess green electricity generation cost are developed. The modeling has shown that the annual increase in the cap for green electricity consumption by 1% will raise the electricity tariff by 3%, which is not a significant financial burden for consumers. The proposed changes in the tradable green certificates system can be an effective management tool to achieve the required amount of electricity from renewable energy sources in the country’s total electricity consumption and to foster the development of the Ukrainian renewable energy sector.

Full textAbstract:
This paper presents the expansion of renewable energy sources of electricity generation over the last 10-15 years, based on statistical data for Hungary and for the EU-28 member states. The share of renewable energy in electricity production was almost 30% in the EU28 in 2016, while in Hungary it was only 7%, which is the second lowest share in EU member states. In Hungary, the share of nuclear energy is still high in electricity production, and the proportion of biomass in renewable energy in Hungary is very high compared to the EU-28 average. An important issue for Hungary is how to reduce the share of nuclear energy in the longer term. Finally, the paper highlights the essential elements of the Hungarian METAR subsidy system aimed at encouraging the production of electricity (and heat) energy from renewable energy sources while minimizing the burden on end users.

At the international level, the problem of the need to increase the contribution of renewable energy sources to domestic electricity demand is highly relevant. Since the production of renewable energy sources is quite expensive, many countries are developing various state and market incentives for investment in such energy sources. One such incentive is renewable energy certificates. The role of these certificates in the development of global renewable energy markets is invaluable. They not only help businesses achieve their goals in the field of renewable energy, but also reduce consumer payments for other renewable energy development programs. This article analyzes the current trends in the use of renewable energy certificates in the world and identifies the prospects for their use in the Russian Federation. In addition, the author of the article studied the issue of cost-effectiveness of renewable certificates. In order to assess the positive economic impact of the application of the certification system, calculations have been made to reduce the financial burden on participants in the Wholesale Electricity and Power Market by taking into account the funds received from the sale of these certificates to reduce payments by market participants to generators based on renewable sources under the program of agreements on the provision of capacity for generating objects operating on the basis of renewable energy sources, from the date of the start of supply of electric energy and of the last planned facility until the date of the last payment under the power capacity agreement. In addition, the author of the article studied the need for renewable energy certificates not only to obtain reliable data on the use of renewable energy sources, but also to create efficient electricity markets using renewable energy sources around the world.

Full textAbstract:
The world is moving in the direction of using electricity derived from renewable sources. With the mass production of devices to enable the production of energy from such sources (wind, solar and tides), peak power capacity is competitive with that of deriving the electricity from fossil fuel. The problem is that the profile of power production does not match that of the requirements. This problem is not new, but it has become more acute: due to the extremely peaky nature of the power from the new sources, unless there is efficient energy storage, it is necessary to maintain the capacity to generate power to cover the full load in certain climatic conditions. While nuclear power is clean and would be ideal for satisfying the requirements of base load, the capital cost of nuclear plants (which should include that of decommissioning) makes the real cost of such power more expensive than that which can now obtained from renewables (and from burning gas or coal, of course). Ever since there have been electrical grids, companies have looked for ways to efficiently store energy so that power can be delivered on demand with minimum capital investment. A wide range of technologies is employed, and is being developed, so that everyday needs can be met. Energy storage is resource neutral: it allows us to use electricity from any power source more efficiently. However, it involves considerable capital investment, and can occupy a lot of space. The idea of moving towards reliance on renewable sources of energy has been taken up by a large segment of the population but there is technically still a lot to do, especially with regard to the essential corollary of energy storage. In addition to the challenge of producing the means to store energy, many other issues must be addressed. These include maintainability and longevity of the equipment (both for producing the energy and storing it). In this report we explore and compare the different methods available for storing energy and investigate trends.

Full textAbstract:
Chile has become one of the first few countries where renewable sources compete directly with conventional generation in price-based auctions. Moreover, the results of energy auctions during the last few years show a remarkable transition from conventional fossil fuels to renewable energies. In fact, the energy auction in 2017, to provide energy to customers from distribution companies, achieved a massive expansion in renewable technology at one of the lowest prices in the world. These positive results prompted the question if such results were permanent or temporal due to factors with limited effects. In this regard, this paper studies the key factors that drove the significant rise of renewable technologies in Chilean energy auctions, obtaining valuable lessons for regulators, not only in Chile, but also in the region and the world. For this purpose, we considered a well-proven method based on a hybrid multicriteria decision-making model to examine and prioritize the main drivers of the expansion of renewables in auctions. The results showed that some specific characteristics of the auction design, particularly the hourly supply blocks, the lead time for project construction, and contract duration, were the most significant drivers for the expansion of renewables in energy auctions. Moreover, the results showed that, provided that the auction design accommodates for such drivers, solar energy ends up as the most attractive technology in the Chilean auctions. The research also shows the main findings are robust by the application of a probabilistic sensitivity analysis.

Full textAbstract:
Increasing the use of renewable energy sources is one of the strategic objectives of the European Union. In this regard, it seems necessary to answer the question: which of the member countries are the most effective in its implementation? Therefore, the main goal was to distinguish groups of European Union countries, including the Visegrad Group, differing in the use of renewable energy sources in transport, electricity, heating and cooling (based on cluster analysis). All members of the EU were determinedly selected for research on 1 February 2020 (27 countries). The research period embraced the years 2009–2019. The sources of materials were the literature on the topic and data from Eurostat. Descriptive, tabular, graphical methods and cluster analysis were used in the presentation and analysis of materials. In 2019 wind and hydro power accounted for two-thirds of the total electricity generated from renewable sources. In 2019, renewable energy sources made up 34% of gross electricity consumption in the EU-27. Wind and hydro power accounted for two-thirds of the total electricity generated from renewable sources (35% each). Moreover, it was determined that there were 5 clusters that differed in their use of renewable energy sources. The highest average renewable energy consumption in transport, heating and cooling in 2019 was characterized by a cluster consisting of Sweden and Finland. In contrast, the highest average renewable energy consumption in electricity was characterized by a cluster consisting of countries such as: Austria, Croatia, Denmark, Latvia and Portugal. Finally, in a group that included countries such as Belgium, France, Luxembourg, Malta, the Netherlands and the entire VG (Hungary, Czechia, Slovakia and Poland), renewable energy consumption rates (in transport, electricity, heating and cooling) were lower than the EU average (27 countries).

Increasing of intermittent production from renewable energy sources significantly affects the distribution of electricity prices. In this paper, we analyze the impact of renewable energy sources on the formation of electricity prices on the Day-Ahead Market (DAM). The case of the 4M Market Coupling Project is analyzed: Czech-Slovak-Hungarian-Romanian market areas. As a result of the coupling of electricity markets and the increasing share of renewable energy sources, different situations have been identified in which prices are very volatile.

Purpose: While the relationships between energy or electricity consumption and economic growth are of great interest to economists, previous studies have not examined the dynamic effect of electricity production on industrial and agricultural output growth in Nigeria; this study attempts to fill the gap. This study thus investigates the dynamic effects of electricity production from renewable and non-renewable energy sources on industrial and agricultural output growth in Nigeria. Design/methodology/approach: This study disentangled electricity production by source - into renewable and non-renewable - and employed a Structural Vector Autoregressive (SVAR) and other time series econometrics analysis. Findings: This study found that electricity production from both sources has a slight impact on the growth of the Nigerian industrial and agricultural sectors. In addition, this study supports the existing claim that economic growth and energy are linked and thus disproves the neo-classical assumption of the neutrality hypothesis. Research limitations/implications: This study considers annual data for all the variables due to the available data frequency for electricity production. However, the study assesses the validity of the estimated SVAR, and the results show that the analysis is robust for this study. Originality/value: This study contributes to the existing empirical literature by disentangling electricity production into renewable and non-renewable- and then examine their impacts on the crucial sectors of the Nigerian economy. This study shows that electricity production from the two energy sources contributes marginally to the growth of the industrial and agricultural sectors in Nigeria. Therefore, among other policy prescriptions, the author recommends that acceleration of projects that focus on off-grid electricity production under the Nigerian Energy Support Program (NESP) could minimize the current challenges of electricity production and its impact on the economy.

Full textAbstract:
Generating electricity from renewable sources is more expensive than conventional approaches but reduces pollution externalities. Analyzing the tradeoff is much more challenging than often presumed because the value of electricity is extremely dependent on the time and location at which it is produced, which is not very controllable with some renewables, such as wind and solar. Likewise, the pollution benefits from renewable generation depend on what type of generation it displaces, which also depends on time and location. Without incorporating these factors, cost–benefit analyses of alternatives are likely to be misleading. Other common arguments for subsidizing renewable power—green jobs, energy security, and driving down fossil energy prices—are unlikely to substantially alter the analysis. The role of intellectual property spillovers is a strong argument for subsidizing energy science research, but less persuasive as an enhancement to the value of installing current renewable energy technologies.

The article proposes a new optimization model of systemic relationships and effects in the formation of a pricing policy for electricity from combined sources of electricity, taking into account indicators of anthropogenic impact and non-renewable resources, socio-environmental and economic interests of society in the distribution of rental income. The model in the end result provides for the formation of a combined model of tariff setting in the energy sector, according to which electricity tariffs for the end user of the corresponding region will combine both market prices for energy generated from alternative sources and prices for energy generated from traditional sources. The authors improved the scientific and methodological approach to identify, formalize and quantify the multiplier effects that arise as a result of a combination of non-renewable and renewable sources of electricity. Also, the article improves the scientific and methodological approach to assessing the benefits of combining different sources of electricity and their advantages when forming a pricing policy within a single energy strategy.

The paper analyzes the energy potential of autonomous power supply based on renewable energy sources in a livestock farm. Based on calculations of the amount of farm waste that act as raw materials for a biogas power plant, the amount of electricity that can be produced from biogas has been determined. The value of electricity generation was also determined when a biogas plant and solar panels are used together in order to fully cover the need for electricity. It has been established that the use of renewable energy sources for autonomous power supply has significant potential for growth, in particular, the generation of electricity by a biogas power plant is calculated according to the minimum indicators for a cattle farm, provides 57% of the required electricity, in addition, there is also thermal energy, which is used for heating farms. The combined operation of the biogas plant and solar panels installed on the roof of the farm allows to cover the need for electricity with a reduction factor of 2.6 solar panels generation. The use of biogas obtained from the waste of a cattle farm and together with solar panels makes it possible to cover the need for electricity with a significant reserve. For a typical farm of 100 cattle, this stock is about 80%. The use of which is possible with the use of energy storage devices and the formation of a biogas reserve. It has been established that the electrical power of a biogas plant, which works in conjunction with solar panels, should be at least the average value of the power consumption to provide autonomous power supply to consumers of the livestock farm, especially in the winter months when solar insolation is minimal.

Nowadays, “energy production” and “global climate change and mitigation”, which are in direct relation with each other, are the most important environmental problems waiting for a solution. Renewable and sustainable energy sources provide the most appropriate alternatives for the solution of this problem. In Turkey, one of the important raw material potential of renewable and sustainable energy sources is “Biomass energy”; it is used in biogas production, biofuel production such as biodiesel, bioethanol, biobuthanol and gasification-burning technology. In this study; the potential for agricultural wastes derived from agricultural activities and domestic wastes from Çukurkuyu town of Niğde where the main economic source are agriculture and livestock, were calculated by using incineration technology, which is one of the methods of production of renewable electric energy. In this study, a feasibility study was carried out for the production of renewable electricity from the wastes generated in the town and the potential of renewable electricity generation was determined by the obtained data. Moreover, in this study, fossil fuel balance of the electricity produced from biomass was determined and potential for greenhouse gas emission reduction was determined. Thus, as an alternative to fossil fuels, energy production from renewable sources has been determined both in agricultural waste management.

Full textAbstract:
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.

The world is constantly seeking new sources of energy to replace the use of coal and fossil fuels to generate electricity. And a strong source of energy from the ocean is one of the hopes of scientists around the world. Ocean energy is an endless renewable energy source for making electricity used for the world. Marine technology was once considered too expensive to be a viable source of alternative clean energy, especially compared to already developed products such as wind and solar. However, with the increased price of oil and the issues of global warming and national security, U.S. coastal sites are looking to add ocean energy to their renewable energy portfolios. This paper gives an overview of ocean energy technologies, focusing on two different types: wave, tidal. It outlines the operating principles, the status, and the efficiency and cost of generating energy associated with each technology.

The aim of the article is to study the implementation of innovative projects for the use of renewable energy sources in the “economy of the future”. According to the concept of “green" energy transition, the following areas of "economy of the future" are identified: energy efficient industry, buildings, heat energy; electric transport; circulating economy, waste reduction; support for research and innovation on electricity storage, production and storage of green hydrogen; digitalization and technological changes; renewable energy sources – wind, solar, bioenergy. It is proved that renewable energy sources can meet 80% growth in electricity demand over the next 10 years. By 2025, renewable energy sources will displace coal as the main means of electricity generation. If states adopt more aggressive policies, the role of renewable energy will be even more active in the next five years. It is proved that it is important to create an appropriate market environment to attract large-scale private investment in innovative renewable energy projects. After all, without sufficient investment, networks will be a weak link in the transformation of the electricity sector, which will affect the reliability and security of electricity supply. The transition to renewable energy sources in the general energy supply, including transport and heating, is most active in large cities. To transition the city to the “green” energy, the issues of attracting investment, changing consumer behavior, integration of electricity with heat supply and transport, the state of existing energy infrastructure (electricity, gas, heating networks), distribution of energy consumption between sectors (buildings, mobility) and players in supply (large energy companies, enterprises, cooperatives).
The research of the basic tendencies of realization of projects of use of renewable energy sources in Ukraine is carried out. To ensure competitive conditions for the production of electricity from alternative energy sources, the introduction of incentive mechanisms and the installation of capacities for the accumulation of electricity at power plants is envisaged. Financial support for renewable energy at the state level is provided in two areas: tax benefits and credit support. Among the tax benefits and mechanisms in world practice are the following: investment tax credit; production tax credit; mechanism of partial or full compensation of interest for the use of loans by industrial companies and individual farms for the installation of energy storage systems; mechanism for exemption from taxation of imported equipment for energy storage systems, etc. However, Ukraine has not yet taken sufficient legislative and diplomatic steps to do so. Important are the problems of balancing the network, defaults and debts to market participants, the restructuring of the “green” tariff.

Abstract When talking about the future of Europe we also think about alternative energy sources. It is up to national governments to decide how to encourage investments in this field in order to contribute to the 20-20-20 EU-objective. Until the network delivery cost for electricity produced from renewable sources will be comparable to the cost for energy from traditional sources ("grid parity"), the development of businesses and markets for electricity from renewable sources is going to be driven by support schemes. The state of the grids and the facility of grid-access constitute another two key factors influencing the development of this sector. Last but not least, the question of policy consistency is raised within the business community. Over the past years some support schemes have proved to be more effective than others, and grid conditions have also evolved. Policies supporting the development of renewables also changed at EU-level and at national levels. Based on statistics, scientific literature and the feedback of the business community, this study aims to analyse the development of renewable energy sectors in the European Union by comparing Germany’s and Romania’s experience. Also this study describes the current and expected future market situation in these countries relying on data gained from questionnaires and interviews with specialists in the renewable field.

Over the past three decades there has been a steady growth in total electricity generation in Asia. Although most of this electricity came from natural gas and coal, renewable electricity generation also has significantly contributed to total electricity generation, with hydro being the largest source of renewables-based electricity. In this study, we analyze the dynamics between economic growth, emissions of carbon dioxide (CO2) and the share of renewable electricity in total electricity generation in eleven Asian developing countries over the period from 1980 to 2010. The Structural Vector Autoregression (SVAR) methodology is used to study the interactions among the variables and to analyze the impact of expansion of renewable electricity on per capita emissions and economic wellbeing. Our results show that the majority of middle-income countries in Asia are likely to face a trade-off between economic growth and environment sustainability at least in the early years. Therefore, such countries may need to implement policies complementing renewable energy generation and improving energy efficiency.

The usage of renewable energy sources and energy storage devices allows an enterprise to reduce its electricity supply costs. Significant savings can be achieved only in the case of a well-organized system of managing energy flows of the enterprise and electricity consumption. The puprpose of the study was to analyze the existing storage devices and renewable energy sources, and on the basis of the analysis, introduce an approach to organizing energy supply of the enterprise based on the usage of storage devices and renewable energy sources. The approach introduced implies the electricity purchase schedule curve optimization to minimize the total costs. The purchase schedule curve optimization for the case of energy storage usage is an ill-posed problem. Within the framework of solving the problem, the form of the curve was formalized to a piecewise constant function, which made it possible to solve it by applying multi-criteria optimization based on a modified method of directed random search. We analyzed a model case, for which an optimal purchase schedule curve was obtained using storage devices and solar panels, and the achievable economic effect from their use was graphed. The maximum value of operational costs, which makes the usage of energy storage and renewable energy source efficient, was found
