Literature has highlighted the existence of a gap in clean fuel usage between the social groups in most emerging nations across the world, which is detrimental to global efforts to achieve Sustainable Development Goal (SDG) 7 (access to clean energy) and SDG 10 (reducing inequalities) and just energy transition with recognition justice. This paper, assesses the clean fuel gap across social groups in India using three rounds of representative data (2004, 2014, and 2018) by applying the logit model, exogenous switching treatment effect regression (ESTER), and the Blinder–Oaxaca Decomposition Model. Such an analysis is instrumental in identifying the clean energy usage gap and its causes, thereby providing insight to policymakers to design policies to achieve just energy transition and carbon neutrality by 2060. The results show a substantive clean fuel gap between social groups in India, which is a cause of concern for just energy transition. Clean energy utilization gaps among social groups are alarming across geographical locations and consumption quartiles, highlighting the importance of recognition justice for just energy transition. The results show that in rural areas, only 19.6 % of the General Caste households and 14.5 % of the disadvantaged social groups (Scheduled Tribes, Scheduled Castes, and Other Backward Class) in quartile one use clean energy, while in urban areas, the shares are 60.4 % and 46.3 %, respectively. To achieve a just distribution of the benefits of energy transition, energy policies should focus on disadvantaged social groups and simultaneously target General Caste households from a lower economic status and those residing in rural areas, indicating the need for targeting the neglected regions. [Display omitted] • Clean energy use has steadily increased among all social groups in India, indicating some improvement in energy justice. • Clean energy access gap among social groups has declined, but this gap still persists. • Scheduled Castes and Scheduled Tribes are the most disadvantaged social groups in terms of clean energy. • All social groups from low-income families have limited access to clean energy. • All social groups from households with low education have limited access to clean energy.

India as a developing economic power, has to rely much on its energy sector for growth and development. The growth is largely interlinked with the availability of energy and its judicious utilization. Also involved is the question whether the available energy is environmentally acceptable and technically viable. With the growth of country's economy, per capita power consumption has also increased resulting greater demands for power. India's power sector is mainly dependent on conventional or fossil fuels i.e., coal (60.1%) and gas (8.7%) (2015). India has around 10% of the world's coal reserves that will last for about another 30–40 years at the present consumption rate. The use of conventional fossil fuels has a negative impact on the environment due to the emission of harmful greenhouse gases. On the other hand, according to the Ministry of New and Renewable Energy (MNRE), Government of India, the country has untapped source of renewable energies such as, wind, solar power, nuclear energy and biomass. Globally, depletion of conventional fuel resources, is increasingly turning the focus on non-conventional sources of energy. The present paper is a review of biomass energy, its sources and its energy efficiency. Even though sources of biomass fuels are widely available all across India, these are still largely underutilized. According to the available statistics, in India the share of renewable energy has increased from 7.8% to 12.3% during 2012-13 and to 12.95% as on 31st March 2014, this paper also highlights the challenges and advantages of biomass energy over conventional fuels as well as utilization and applicability of biomass in sintering process as a replacement for coke.

Fossil fuels such as coal, petroleum, and natural gas have been used as the major sources of energy in the recent past. However, the negative environmental impacts associated with the emission of the greenhouse gases from these conventional energy sources forced to realize the importance of renewable energy resources. At the same time, the average annual exponential rate of population growth in India needs increasing amounts of fresh-water for the basic necessities. This might result in water scarcity as the overall population in India is expected to increase to 1.60 billion by 2050. It has been forecasted that, by the year 2040, India will rank 40th in the world in terms of water scarcity. To meet the rising fresh-water demand, desalination is an intelligent and sustainable option for India, which has a very long coastline measuring 7517 km. In this paper, an attempt has been made to provide a comprehensive review of water scarcity in India and suggest a possible solution, which is implementing desalination technologies coupled with renewable resources. The paper reviews the ground water scenario in India and the global desalination market. We summarize the energy consumption in various desalination processes and provide a brief outlook of the desalination techniques in India. Apart from this, desalination using non-conventional sources such as solar, wind, and geothermal energy is discussed. In addition, factors affecting the environment due to desalination and the potential counter measures are presented. This review aims to provide an awareness of the projected water crisis in India, in the coming decades, and is also aimed to help the policy makers for selecting an appropriate desalination technology.

With 21,136 MW of wind energy installed in 2014, India is considered a success story in terms of net installed capacity. Few existing studies on Indian wind energy have highlighted the important role of institutions, and how they stemmed from the work of advocacy groups; studies also tend to focus on short time periods. This paper uses the notion of collective institutional entrepreneurship to analyze Indian wind energy across three time periods (1985–1995, 1995–2003, and 2003–2013). The analysis shows that Indian wind power development was driven by collective efforts of institutional entrepreneurs using two aggregated strategies, that is, supportive techno-economic and socio-political networks and an indigenous innovation infrastructure. The paper highlights setbacks, controversies, and tensions between various entrepreneurship groups and argues that actions must be taken for including actors who have been marginalized.

Rapidly increasing energy demand and growing concern about economic and environmental consequences call for renewable/sustainable energy technologies׳ adoption in India. Renewable/sustainable energy technologies have faced a number of constraints that have affected their rate of adoption. In this paper an attempt has been made to identify and rank the major barriers in the adoption of ‘renewable and green’ energy technologies in the Indian context. Twenty-eight barriers have been identified from an extensive literature review. These identified barriers have been categorized into seven dimensions of barriers, i.e. Economical & Financial; Market; Awareness & Information; Technical; Ecological and Geographical; Cultural & Behavioral; and Political & Government Issues. Analytical Hierarchy Process (AHP) technique has been utilized for ranking of barriers to adopt renewable/sustainable technologies in the Indian context. All pair comparisons in AHP have been made based on experts’ opinions (selected from academia and industry). Sensitivity analysis has also been made to investigate the priority ranking stability of barriers to adopt renewable/sustainable technologies in the Indian context. This paper may help practitioners, regulators and academician focus their future efforts in adoption of ‘renewable/sustainable energy technologies’ in India. Further, this understanding may be helpful in framing the policies and strategies towards adoption of renewable/sustainable energy technologies. [ABSTRACT FROM AUTHOR]

The COVID-19 pandemic has dramatically altered global energy consumption, particularly affecting investment in renewable energy projects. In India, strict shelter-in-place orders enforced during March 2020 have since led to a considerable change in public and private sector investments in planned renewable energy installations. In this paper, we attempt to highlight trends in energy consumption and installed renewable energy capacity noted in India during a period concurrent with the shelter-in-place orders. We discuss recent policy measures and additions to installed renewable energy capacity, and propose key policy recommendations that may help the sector adopt a growth trajectory similar to one noted pre-pandemic. This paper is organized into four main parts. In the first section, we draw focus to India's renewable energy policies and pay special emphasis on recent interventions and campaigns targeted towards achieving high growth rates in the sector. We briefly discuss the need for effective public-private partnerships in order to meet these targets. In the second part, we quantitatively characterise the growth of renewables in India. We present an overview of several mechanisms and missions the government has launched in line with their policy to mitigate the environmental impact of India's energy mix. In the third part, we analyse the decrease in electricity demand in India from 24 March to 30 June 2020, a period concurrent with shelter-at-home orders issued by the Government. We also characterise changes in installed renewable energy capacity between March to December 2016–2020 to provide causal evidence of the effect of the pandemic on the growth of renewables. In this section, we also compile and analyse data on state-wise stressed assets across renewable energy generators in the country. Lastly, in the fourth and final portion of this paper, we highlight policy recommendations that may help the sector overcome logistical and financial bottlenecks in the short-term. We do this with the hope of outlining key measures that decision makers may employ to achieve pre-COVID sectoral growth in the long term. Our recommendations cover three different policy instruments: investment subsidies, operational subsidies, and recommendations for DISCOMs. • The increase in Indian renewable energy capacity installations between February to May 2020 hasseen an increment of 0.75%. • Daily electricity demand has decreased by 18.8% after the announcement of the shelter at home orders. • Immediate effects of the pandemic on the Indian renewable energy sector have been quantified. • A 3 tier system may be adopted to regulate incentives among renewable energy power producers. • Key policy recommendations to improve the fitness of the renewable energy sector have been discussed.

The aim of this research is to examine the link between CO 2 emissions, hydroelectricity consumption, urbanisation and real GDP in China and India during the period of 1965–2013. The long-run cointegration is investigated by the autoregressive distributed lag (ARDL) bounds testing approach, which is augmented with structural breaks. We employ the ARDL cointegration test to establish long run relationship in the variables. Furthermore, we use the ARDL to show that real GDP and urbanisation have long-run positive impact on emission, while hydroelectricity consumption exerts long-run negative impact on emission in both countries. The results support the existence of environmental Kuznets curve (EKC) hypothesis in China and India. Besides, the paper assesses the causal link between the variables by using Granger causality procedures and the results show that there is long-run bidirectional relationship between the variables in both countries.

The aim of this paper is to test whether income inequality contributes to environmental degradation in China and India, where both countries are giving a great concern about the implications of their unsustainable energy consumption to the environment not only to themselves but also to the global environmental sustainability. By applying the bounds test approach to cointegration we found in both countries a long-run but not a statistically significant relationship between income inequality and CO 2 emissions both in the long-run and in the short-run. The robustness of our cointegration results is also ascertained by using three different long-run tests. Furthermore, applying the variance decomposition analysis to examine the dynamic causal relationship between the Gini coefficient of income distribution and CO 2 emissions, we found that income inequality was the least important factor in determining CO 2 emissions and that there was no causality running in any direction between CO 2 emissions and income inequality in both countries. Still income and energy consumption are the major determinants of CO 2 emissions in both countries. Nevertheless, even though the evidence is not statistically significant, in the case of China it indicates that reducing income inequality can have a positive impact on environmental quality, while in India redistributing income to improve environmental degradation may not be effective.

As the world's fastest growing major economy and home to nearly one-fifth of the worlds population, India a vibrant democracy is in the midst of a profound transformation and rapid urbanization. Urbanization improves the quality of life of people while promoting economic growth; however it also increases energy consumption and is capable of generating an energy crisis. Urbanization has a significant impact on Carbon Dioxide (CO 2 ) emissions as well. This paper empirically investigates the temporal, dynamic and causal relationships between urbanization, energy consumption and emissions. The study also aims to understand the urbanization process in India, in terms of the level and tempo of urbanization and the urban growth morphology, by utilizing the census data of 1901–2011. The rise in energy consumption and resulting emissions in the context of rapid urbanization is also reviewed. To address these problems the study recommends a series of measures and a set of strategies that include energy intensity and emission intensity reduction measures through continuous monitoring, information feedback systems, introduction of industrial energy quota management, incentives for energy efficient facilities, shutting down of inefficient facilities, and setting up of smart residential buildings. Reduction of distribution and transmission losses by investing in smart grids is also highly recommended. [ABSTRACT FROM AUTHOR]

China and India accounted for two-thirds of the world׳s rise in energy use between 2000 and 2012. This paper aimed to calculate the P (population)– A (affluence)– T (technology) effects of energy use in China and India – the world׳s two most populous and largest developing countries. To this end, a combination of the IPAT method and the logarithmic mean divisia index technique, and annual time-series data on population, energy consumption, and gross domestic product during 1970–2012 are used. In China, a 12.53-fold growth of energy use emissions from 1970 to 2012 is driven by a combination of rapid growth in individual income and slow growth in population, with offset by technological advancement since 1980. The accelerating rise in energy use since 2000 is a result of accelerating growth rates in individual income and a reversal of earlier declining in energy intensity (technological advancement). Unlike China, the long-term rise in energy use exceeded the long-term rise in individual income in India. In addition, a strong trend of decline in energy intensity has not yet occurred in India. Thus, a 7.39-folds growth of Indian energy use for 1970–2012 was a result of relatively rapid increase in population and relatively slow increase in income, without effective offset by technological advancement. It suggests that market-oriented economic and energy reforms need to send the correct price signal to promote energy-efficient technologies thus improving energy efficiency, which is the key to a sustainable energy future in China and India.

Renewable energy can play a strategic role in India in meeting the country’s growing energy demands, as well as combating climate change. Policymakers have recognized this potential and over the last decade have intensified their efforts towards creating a conducive regulatory and policy framework. Policy instruments such as renewable obligations, feed-in-tariffs and generation based incentives have specially aided the transformation towards large scale generation, enabling higher efficiency and lower costs of generation. However, financing has emerged as a significant barrier for sustaining the momentum gained in recent years. Given this background this paper provides an overview on the evolution of large scale generation and the consequent changes in financing requirements. It further reviews the emerging trends and barriers in the financing landscape and analyses the impact of policy performance in this context. Finally, it considers the design of a national renewable finance framework complete with targeted finance push instruments that can complement existing demand pull policies in facilitating investment.

Solar Tower technology has gained considerable momentum over the past decade. Unlike the parabolic trough, Solar Tower has a lot of variants in terms of type of receivers, working fluids, power cycles, size of heliostats, etc. Most of the literature available on this technology does not address in great depths, details of various parameters associated with tower technology. A detailed examination of plant parameters is required in order to perform a potential assessment, design basis or feasibility analysis. This paper aims to assess the principal parameters of existing plants, namely, solar to electric conversion efficiency, mirror and land area per MW e of equivalent capacity, packing density, field layout configuration, receiver size, tower height and gross costs of plants, wherever data is available. Based on this global review of existing plants, it is observed that, the annual solar to electric conversion efficiencies has an average value of 16% and the packing density has an average value of about 20%. Since most of the existing plants have been constructed for demonstration purposes, the true potential of this technology has not yet been realised. Using this assessment as a basis, the technical, financial and policy drivers and barriers for adopting tower technology in India are discussed. It is seen that based on indigenisation prospects, tower technology with external cylindrical or cavity receivers with storage could be adopted. The role and significance of this technology is brought out in the context of the Jawaharlal Nehru National Solar Mission (JNNSM) in order to achieve grid-connected solar power. It is estimated that around 1800 MW of grid connected Solar Tower plants could come up under this mission by 2022. [ABSTRACT FROM AUTHOR]

Increasing energy demands and commitments in relation to climate change have accelerated the deployment of solar power globally, especially in India. Grid-connected solar capacity in the country has increased ∼11 times in just five years, from 2.6 GW in March 2014 to 28.18 GW in March 2019. However, this development has inevitably also led to the emergence of significant volumes of solar photovoltaic (PV) waste, which will only increase in the upcoming years, a considerable challenge for its waste management system. The environmental and human health risks associated with the unscientific dumping of solar PV waste have been well established in the existing literature, presenting the need to develop an effective strategy to manage this emerging waste stream. This paper presents a review of literature about India's solar PV waste management sector with a view to understanding the ground realities and identifying challenges and barriers that hinder the adoption of a regularised strategy for its management using the DPSIR framework approach. It goes on to propose a regulatory framework aimed at mainstreaming the end-of-life (EOL) management of solar PV waste in India after evaluating strategies that have already been used worldwide. In line with the Extended Producer Responsibility (EPR) concept, a multistakeholder, multi-sectoral and systematic approach has been adopted to develop a specific regulatory framework for India. The framework was subjected to a SWOT analysis to evaluate its functionality. The SWOT analysis indicates that one of the critical strengths of the framework is that it is based on a participatory approach to be adopted by all stakeholders for managing this emerging waste stream. [Display omitted] • Solar PV waste at EOL emerging as a prominent waste stream in India. • EOL solar PV waste management can foster Resource Efficiency and Circularity. • Systems approach and multistakeholder required to manage solar PV waste. • Self-standing EPR legislation is appropriate for EOL solar PV waste management.

An extensive canal irrigation network in South Asia has developed over the past 170 years that consists of thousands of kilometers of constructed channels and distributaries. These canals cut across many energy-poor regions along their paths. In India, this canal network provides a unique opportunity for renewable energy generation that is yet to be realized. Existing technologies for energy generation on canals include small hydropower on canal falls and, recently, canal-top solar panels. In addition, opportunities for hydrokinetic generation in irrigation canals have received limited attention. This paper develops a novel canal-network level framework for energy planning that integrates generation with local energy needs in a canal-corridor. This framework for integrated spatial assessment analyzes the supply of renewable energy generation potential and the demand of unmet energy needs in a canal-corridor, using the Upper Ganga Canal in Uttar Pradesh, India as a case study. We consider the theoretical and technological potential of hydropower and solar power generation and develop three indices to assess the agricultural, domestic, and composite unmet power demand of the canal-corridor. Our results show an overall theoretical potential of 149.1 MW and 13,213 MW for small hydropower and solar power, respectively, which could more than help meet the current 18 hours per day electricity service standard in Uttar Pradesh. The framework uses standardized irrigation and census datasets and therefore is generalizable for canal networks across India and South Asia more broadly. • Irrigation canal energy technologies include small hydro and canal-top solar power. • Novel canal-network level framework for energy planning. • Integration of generation potential with local energy needs in a canal corridor. • Theoretical and technological potential of energy generation on canals. • Three indices for agricultural, domestic, and composite unmet power demand.
