Meeting the rising energy demand and limiting its environmental impact are the two intertwined issues faced in the 21st century. Governments in different countries have been engaged in developing regulations and related policies to encourage environment friendly renewable energy generation along with conservation strategies and technological innovations. It is important to develop sustainable energy policies and provide relevant and suitable policy recommendations for end-users. This study presents a review on sustainable energy policy for promotion of renewable energy by introducing the devel...

Many policy analysts believe that once electricity from renewable energy becomes less expensive than electricity from fossil fuel, new renewable energy facilities will be built quickly across the United States. Cost-effective renewable energy has largely been achieved, but there appear to be substantial barriers to building new renewable energy facilities. We identified 53 utility-scale wind, solar, and geothermal energy projects that were delayed or blocked between 2008 and 2021 in 28 U.S. states. Using multi-level qualitative analysis, we have identified seven key sources of opposition. Of t...

The world’s ever-increasing population, combined with economic and technological growth and a new, modern way of life, has led to high energy demand and consumption. Fossil fuels have been the main energy source for many years, but their use has many negative impacts on the environment. This has made the transition to renewable energy sources necessary in order to address climate change and meet the 1.5 °C goal. This paper is a review of the different types of renewables, their potentials and limitations, and their connection to climate change, economic growth, and human health. It also examin...

Energy communities is a new, but already successful prosumer model of the local energy systems' construction. It is based on distributed energy sources and the electricity consumers' flexibility who are the members of the community. In search of the most effective ways to interact within themselves and with the external energy system, local energy communities become platforms for exciting experiments in the field of new energy practices including local markets for flexibility, building cooperative microgrids, achieving energy autonomy, and many others. This work aims to present a unified appro...

Renewable energy (RE) is the key element of sustainable, environmentally friendly, and cost-effective electricity generation. An official report by International Energy Agency (IEA) states that the demand on fossil fuel usage to generate electricity has started to decrease since year 2019, along with the rise of RE usage to supply global energy demands. Researches on RE technologies are continuously growing in order to enhance the performance of RE generation, especially in term of energy conversion efficiency. The aim of this review paper is to understand and study further the current RE tech...

This study seeks to evaluate potential solutions to Pakistan's energy shortages based on a renewable green hydrogen source provided by geothermal, wind, biomass, and solar energy. To this end, the application of multi-Criteria Decision Analysis (MCDA) and the Fuzzy-analytical hierarchical process was tested on four primary criteria: social acceptance, economic, commercialization, and environmental. The Data Envelopment Analysis (DEA) is used to analyze the development of hydrogen energy using existing renewable sources under the set parameters. Based on results from the fuzzy-led DEA study, th...

Abstract Wind power, solar power and water power are technologies that can be used as the main sources of renewable energy so that the target of decarbonisation in the energy sector can be achieved. However, when compared with conventional power plants, they have a significant difference. The share of renewable energy has made a difference and posed various challenges, especially in the power generation system. The reliability of the power system can achieve the decarbonization target but this objective often collides with several challenges and failures, such that they make achievement of the...

Nowadays, the growing world population, climate change, pollution, rising consumer demand, and resource exploitation have contributed to a freshwater shortage. Hence, water desalination is heavily used for freshwater production. Meeting water demands in a cost-effective, efficient, and environmentally friendly manner requires the right combination of renewable energy and desalination technology. In this paper, an extensive review of various renewable energy-based desalination technologies is presented. The different types of energy like wind, solar thermal and photovoltaic, geothermal, wave an...

Simulation results illustrate that the proposed energy optimization model optimizes the performance of smart microgrid in aspects of operation cost, pollution emission, and availability compared to the existing models with/without involvement in hybrid DRPS and IBT.

India is the fifth economic power in the World, and 20% of its GDP is contributed by the agriculture and allied sector. The agricultural sector entails various activities involving land preparation, irrigation, crop growth, harvesting, food processing, etc. For meeting the current agricultural energy demand in India, renewable solar energy has come up as a prime energy source that can reduce the farmer’s dependency on the use of conventional energy sources. The regular usage of fossil fuels leads to its depletion and releases considerable CO2 into the atmosphere. It is estimated that 4600 GW o...

Renewable energy sources (RESs) such as wind and solar are frequently hit by fluctuations due to, for example, insufficient wind or sunshine. Energy storage technologies (ESTs) mitigate the problem by storing excess energy generated and then making it accessible on demand. While there are various EST studies, the literature remains isolated and dated. The comparison of the characteristics of ESTs and their potential applications is also short. This paper fills this gap. Using selected criteria, it identifies key ESTs and provides an updated review of the literature on ESTs and their applicatio...

The article presents an analysis of the statistical relationship between the determinants of and barriers to the development of renewable energy sources (RESs) in the macroeconomic system and the development of renewable energy source consumption in individual European Union countries. The article considers four key categories of RES development barriers in the European Union: political, administrative, grid infrastructural, and socioeconomic. The work is based on publicly available historical data from European Union reports, Eurostat, and the Eclareon RES Policy Monitoring Database. The empi...

The energy transition literature assumes that renewable energy sources are more evenly distributed globally than fossil fuels. This assumption implies that the shift from fossil fuels to renewables will enable more countries to pursue energy self-sufficiency and end their dependence on imported energy. However, if the assumption is wrong, the energy transition will depend on transboundary electricity or hydrogen trade, creating new international relationships and opportunities for both cooperation and conflict. The contribution of this study is to test the assumption of the even distribution o...

This study evaluates the effect of renewable, non-renewable energy consumption and economic growth on unemployment rate across 51 US states over the period 1977–2017. We applied a fixed effect model and a Seemingly Unrelated Regression Equations (SURE) model, which allows for an unknown form of cross-sectional dependence and slope heterogeneity. While the results of the fixed effects model indicate the negative and positive effects of non-renewable and renewable energy consumption on the unemployment rate, respectively, mixed results were received by employing SURE model at the state level.
