This study comprehensively considers any input and output that has a certain physical dimension, utilizes the super slacks-based measure directional distance function data envelopment analysis (DDF-DEA) model to measure global energy performance in the period 2010–2016, and compares regional differences in Americas, Europe and Asia. We employ contained directional, non-directional, and undesirable inputs and outputs, which include population number, fossil fuels energy consumption, gross capital formation, gross domestic product, renewable energy consumption, and carbon dioxide emission. From the full energy efficiency and ranking of the DDF-DEA approach herein, the empirical results show that Trinidad and Tobago exhibits the best efficiency (2.8194) and Uzbekistan has the worst efficiency (0.5734). The best regional energy performance is Americas, and the worst is Asia for 2010–2016, showing that regional energy policies have a significant impact. The Environmental Performance Index is an important sustainable environment index, and most Environmental Performance Index levels are quite consistent with the trend of energy efficiency and ranking with DDF-DEA in this study. The energy efficiencies of the higher Environmental Performance Index group and higher renewable energy consumption group are significantly larger than the lower Environmental Performance Index group and better than the lower renewable energy consumption group, respectively. Therefore, we suggest that all countries should adjust their future energy using a strategy based on annual Environmental Performance Index. Their goals can be to reduce fossil fuels energy consumption, increase renewable energy use, and reduce undesirable output of carbon dioxide. Doing so will help them to develop their economies while taking into account a sustainable environment, thus achieving sustainable economic development.

Renewable Energy Consumption

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, policies and development of renewable energies and the causal relationship between renewable and non-renewable energies and economic growth using two methodologies. This study first reviews the current state of energy and energy policies and then employs Granger causality analysis to test the relationships between the variables considered. Results showed that renewable energy technologies currently do not have a significant and adequate role in the energy supply of Iran. To encourage the use of renewable energy, especially in electricity production, fuel diversification policies and development program goals were introduced in the late 2000s and early 2010s. Diversifying energy resources is a key pillar of Iran’s new plan. In addition to solar and hydropower, biomass from the municipal waste from large cities and other agricultural products, including fruits, can be used to generate energy and renewable sources. While present policies indicate the incorporation of sustainable energy sources, further efforts are needed to offset the use of fossil fuels. Moreover, the study predicts that with the production capacity of agricultural products in 2018, approximately 4.8 billion liters of bioethanol can be obtained from crop residues and about 526 thousand tons of biodiesel from oilseeds annually. Granger’s causality analysis also shows that there is a unidirectional causal relationship between economic growth to renewable and non-renewable energy use. Labor force and gross fixed capital formation cause renewable energy consumption, and nonrenewable energy consumption causes renewable energy consumption.

The Us

We examine the relationship between renewable and non-renewable energy consumption and economic growth in the United States. While the regime-dependent Granger causality test results for the non-renewable energy consumption and economic growth suggest bi-directional causality in both regimes, we cannot validate any causality between renewable energy consumption and economic growth. The US meets its energy demand from non-renewable sources; as such, renewable energy consumption does not seem to affect economic growth. Given the efficiency and productivity of renewable energy investments, we conclude that it is worthwhile to consider renewable energy inputs to replace fossil fuels given potential benefits in terms of global warming and climate change concerns. In this regard, increasing the R&D investments in the renewable energy sectors, increases in productivity and profitability of renewable energy investments are likely to accrue benefits in the long run.

When assessing energy efficiency, most studies have frequently ignored environmental aspects even though the concept has been widely used in the past. This study evaluates the energy efficiency and environmental performance of South Asia by using DEA (data envelopment analysis) like mathematical composite indicator. We construct a comprehensive set of indicators, including an energy self-sufficiency ratio, energy production over consumption ratio, energy imports, diversification index of energy imports, energy reserve ratio, GDP productivity, energy intensity, per capita energy consumption index, carbon emission index, carbon emission index per unit of energy consumption and share of renewable energy in order to develop an energy efficiency and environmental performance index. Unlike other studies, this study first examines each indicator and then estimates a combined score for each country. The results reveal that Bhutan as a more secure country and Pakistan showed a decreasing trend, while Sri Lanka and India performed satisfactorily. Remarkably, Bangladesh, Nepal and Afghanistan showed a decreasing trend. This study proposes a policy that increases the cross-border trade of renewable energy for long term energy efficiency and environmental performance.

This paper focuses on delineation of ecological viability due to changes of household energy consumption behavior. Then the research also explored the factors (Environmental resources) behind growing ecological footprint. For having a lot of natural elements and high residential characteristics ward-4 of Khulna city was selected as study area. The research followed a three step approaches. At first, geographical and topographical data are analyzed in geo-spatial environment. Which helped to draw the Environmental Performance framework. Geographical Information system (GIS) helps to evaluate the current scenario and past scenario of the resource compatibility of some existing assets. The second phase is all about assessing the residents’ behavior towards energy consumption practice and the influencing factors behind this. The third part showed the environmental performance index (EPI) that include both the socio-economic problems and environmental circumstances using NSA method under the explanatory variables of environmental impact assessment (EIA). Essential natural assets especially water body and the vegetation has decreased at tremendous rate in recent time in Ward-4 with the enhancement of buildup area. This research is totally based on stakeholder perception towards energy consumption pattern and all the further assessment depend on this concept. To assess the behavioral changing factors, it seems that the correlation between income range and energy consumption is positive and linear. It represents that people want to switch high energy consumption appliances with growing wealth. Third phase assess environmental health (measure threat to human health) and ecological vitality (measures ecosystem service and natural resources) under environmental performance index. As the study is mostly involved local residents of study area so the method of neighborhood sustainability Assessment (NSA) is combined with EPI method for scoring the indicators. The approximate score of Environmental Performance Index (EPI) is around 53 percent demarcating the areas existing situation is in moderate rate and diverted from the standard value. This research draw attention to find out environment viability of ward-4 by measuring environmental stress to human health and ecosystem for providing practical guidance to government that aspire to move towards sustainable future.

The Impact

The trade-off between economic growth and ecological improvement has always become an important and difficult issue for many countries, especially for developing countries. Due to a long-term extensive economic growth pattern, the regional resource allocation deviates from the optimal, especially the existence of energy misallocation, which hinders the maximization of economic output. Therefore, considering the characteristics and heterogeneity of resource endowments in different regions and increasing renewable energy consumption, that is, promoting energy transition, is it capable of sustainable development under China’s actual conditions? The exploration of the issue is a core step in the research of the impact of renewable energy on industrial green transformation. Based on the panel data of 30 regions in China from 2009 to 2016, this paper constructs a threshold model from the perspective of regional energy misallocation and empirically tests the nonlinear mechanism of renewable energy consumption to promote industrial green transformation. The results show that China’s energy allocation efficiency is low, there is a certain misallocation phenomenon, and the improvement effect in recent years is not satisfactory. Further, the relationship between renewable energy consumption and industrial green transformation is not a simple linear relationship, but a double threshold effect due to regional energy misallocation. In areas with severe energy misallocation, renewable energy consumption does not have a significant boost to industrial green transformation. Finally, this paper proposes the policy enlightenment of promoting industrial green transformation from the aspects of performance evaluation, market reform, and factor flow.

The Impact

Renewable energy plays a significant role in mitigating C02 emission and boosts sustainable development. Initially, this study examines those factors which create hurdles in adopting renewable energy technology in Thailand. Later, this study examined the impact of renewable energy with other supporting variables on Thailand's total energy consumption. For this purpose, this study used 38 years of data from 1990 to 2018. Initially, the Augmented Dickey fuller test applied to verify the order of integration on indicators, and it confirms that there exists a unit order of integration. Then applied Johansen Cointegration, and it confirms that there are long-run relationships among trade openness, GDP, energy consumption (fossil fuels), financial development, and renewable energy consumption. Further applied Vector error correction model (VECM) to estimates the coefficients on indicators. Results confirm that openness to trade endorses the consumption of renewable energy in Thailand. However, the development of the economy and traditional energy resources creates hurdles to adapting renewable energy in Thailand. Renewable energy technology in Thailand did not significantly impact financial growth and development. After the research, the researcher advised the government of Thailand to adopt and implement the regulations and policies that maximize the magnitude of renewable energy and maximize the portion of renewable energy in total consumption of the overall energy consumption for the country Thailand.
