Top Research Papers on Renewable Energy

Recent global environmental concerns have called for efforts to promote the transition of energy sources toward renewable energy, particularly in emerging countries that prioritize high economic growth. One missing aspect in environmental studies is that renewable energy is composed of traditional and modern ones, where the former could induce environmental and health problems, and the latter could solve them. Accounting for different types of renewable energy, this study evaluates the energy mix evolution in relation to a country's development level (proxied by real GDP per capita) for 23 eme...

An analytical model is developed to analyze the impacts of the interaction of RES and REC polices on the renewable energy investment levels of an electricity generation firm and the carbon emissions and finds that the green tags price under REC policy has a non-monotonic effect on the solar energy investment.

Globally, energy consumption profile is largely dominated by fossil fuels with non-renewable energy sources accounting for as high as 84% of the total energy mix in 2019. Non-renewable energy resources emit high carbon and are subject to resource depletion which create concerns over environmental safety and resource sustainability. To correct these scenarios, there is need to rejig energy mix of individual countries by reducing the share of non-renewable energy and increase that of renewables. Nigeria is one of the countries which has a significant proportion of its energy consumption accounte...

Renewable Energy Resources is a numerate and quantitative text. It covers the many renewables technologies implemented worldwide by harnessing sustainable resources, mitigating pollution and climate change, and providing cost effective services. This fourth edition is extensively updated by John Twidell with global developments as underpinned by fundamental analysis and illustrated by case studies and worked examples. Efficiency of end-use and cost-effectiveness is emphasized. Each chapter begins with fundamental scientific theory, and then considers applications, environmental impact and soci...

The use of fossil fuels has contributed to climate change and global warming, which has led to a growing need for renewable and ecologically friendly alternatives to these. It is accepted that renewable energy sources are the ideal option to substitute fossil fuels in the near future. Significant progress has been made to produce renewable energy sources with acceptable prices at a commercial scale, such as solar, wind, and biomass energies. This success has been due to technological advances that can use renewable energy sources effectively at lower prices. More work is needed to maximize the...

The risks imminent to younger technologies and markets may hinder renewable energy firms' access to financing. This could curtail the investment needed for the transformation of the global energy sector. However, comprehensive analyses of the cost of debt of renewable and non-renewable energy firms are lacking. Here, we empirically analyse the differences between the costs of debt of firms developing and producing renewable energy technologies and of non-renewable energy firms. We use global micro-level data on individual loans matched to firm-level data. The results suggest that renewable ene...

The present study is designed to empirically investigate the effect of financial development, per capita income and trade openness on renewable and non-renewable energy consumption in China. To achieve that, we make use of annual data from 1980 to 2016 and employ several robust time series econometric techniques. Our empirical findings from the fully modified ordinary least squares (FMOLS) technique suggest that increase financial development and per capita income contribute for higher energy demand of both renewable and non-renewable energy sources in China. The evidences also show that their...

The intensification of the use of different renewable energy sources is essential for the fulfillment of the Paris Agreement or for achieving the goals of sustainable development. The environmental impacts of various renewable energy sources have been engaging environmental professionals since their inception. The aim of this work is to collect the most important sizing variables and environmental impacts of hydropower, wind energy, geothermal energy, solar energy and biomass, which have been discussed in the literature. By using the tools of network science, it is possible to jointly manage t...

Iran, endowed with abundant renewable and non-renewable energy resources, particularly non-renewable resources, faces challenges such as air pollution, climate change and energy security. As a leading exporter and consumer of fossil fuels, it is also attempting to use renewable energy as part of its energy mix toward energy security and sustainability. Due to its favorable geographic characteristics, Iran has diverse and accessible renewable sources, which provide appropriate substitutes to reduce dependence on fossil fuels. Therefore, this study aims to examine trends in energy demand, polici...

In a comprehensive analysis of the global transition towards renewable energy, the study revealed significant disparities in adoption rates and technological advancements across nations, while also underscoring the potential for an extensive shift in energy paradigms. Utilizing data from the renewable energy map scenario, findings indicate that renewable energy sources could command up to two-thirds of the global primary energy supply by 2050, a stark contrast to the modest 24% contribution predicted by the reference scenario. European Union countries, particularly Denmark and Germany, emerge ...

This article reviews the literature on the geopolitics of renewable energy. It finds that while the roots of this literature can be traced back to the 1970s and 1980s, most of it has been published from 2010 onwards. The following aggregate conclusions are extracted from the literature: renewable energy has many advantages over fossil fuels for international security and peace; however, renewable energy is thought to exacerbate security risks and geopolitical tensions related to critical materials and cybersecurity; former hydrocarbon exporters will likely be the greatest losers from the energ...

Renewable energy transitions are essential for decarbonizing the world economy and mitigating global climate change. Yet many energy technologies classified as renewable have human health and livelihood implications that jeopardize the lives and wellbeing of those already most vulnerable to the impacts of climate change. The purpose of this study is thus to summarize the documented environmental justice (EJ) impacts associated with renewable energy technologies included in many renewable energy policies globally. Our motivation for this study is to ensure that renewable energy policies incorpo...

Environmental degradation has become a global issue that requires recent studies' emphasis. Non-renewable energy is a significant factor in environmental degradation. Thus, policymakers have switched their focus towards promoting renewable energy production and consumption in all economic activities to secure low carbon economies. Given this scenario, the present study aims to investigate the effect of energy consumption (both renewable energy and non-renewable energy) on carbon emissions under Environmental Kuznets Curve hypothesis in the world's next fastest emerging economies named N-11 eco...

This research work examines the nexus among renewable, non-renewable energy consumption, CO2 emissions, and economic growth in 26 European countries with data obtained from the World Bank database within the time period of 1990 to 2018 to indicate that there exists a long-run nexus among non-Renewable, renewable energy, carbon-monoxide, andEconomic growth.

The long-run elasticity of pooled mean group shows positive impact of economic growth and non-renewable energy consumption on ecological footprint while negative impact is observed in case of renewable energy consumption, globalization and urbanization.

The increasingly severe environmental crisis has become one of the most important issues of international debate at present. The acceleration of environmental problems places considerable pressure on individuals, governments, and policymakers. Greenhouse gas emissions caused by fossil-based energy sources have made clean energy sources, such as renewable energy, a strategic choice. Although renewable energy is a key factor in mitigating environmental problems, analysis of its determinants has certain limitations. Despite studies that focus on macroeconomic and environmental determinants of ren...
