How serious is indoor air pollution (IAP) as a threat to infants and children? This paper estimates the impact of cooking fuel choice – a predominant source of IAP – on under-five mortality in India, where reliance on biomass fuels such as firewood, animal dung, and agricultural waste is pervasive. Leveraging forest cover and agricultural land ownership for identification and nationally representative data, we find that solid fuel use for cooking significantly increases the child mortality rate - mainly driven by neonatal mortality in the first 28 days after birth. The mortality effect is higher for girls than boys and is magnified in relatively small households where there is limited scope for the division of labor between childcare and cooking responsibilities. Among polluting fuels, we find that biomass fuels drive the impact of polluting fuel use on child mortality. [ABSTRACT FROM AUTHOR]

India’s government has a bold goal for deploying renewable energy: 175 gigawatts of electricity-generating capacity by 2022, including 100 gigawatts of solar power. The country has a history of promoting renewable energy and a rapidly growing portfolio of solar and wind projects, but meeting the solar target alone will require a growth rate equivalent to doubling India’s installed solar capacity every 18 months. It will also require a clear understanding of the three factors that drive energy demand in India (access, security, and efficiency); new federal and state policies and incentives; innovative financing for capital investments estimated at $100 billion or more; and additional funding for manufacturing, training, and job creation. Project developers will have to grapple with the cost and availability of land, grid connections, and backup power. To meet the electricity needs of the poor and encourage rural entrepreneurship, India’s energy policies should aim for a mix of grid-connected and decentralized renewable energy sources.

From solar lanterns to home systems and minigrids, distributed renewable energy (DRE) has become increasingly competitive as an alternative to grid extension in household electrification across many parts of the emerging world. We explore how DRE use in Indian households has evolved against the backdrop of massive public investment in grid extension. Using two rounds of the 2015–2018 ACCESS household data from six Indian states, we estimate the impact of household electrification via grid extension on DRE ownership and use. We find that demand for solar microgrids and minigrids has all but disappeared, whereas demand for solar home systems and lanterns as backup solutions to intermittent grid electricity supply continues to grow. Most notably, while grid electrification has increased from 66% to 85%, solar lantern ownership has grown from 1.2% to 5%. The use of DRE as a backup solution to government electrification schemes seems driven by changes in quality of electricity supply. These analyses confirm that intermittent grid electricity supply is key to understanding the solar lantern's continued popularity. The results show that where population density, household income, and government commitment all favor grid extension, the most affordable DRE technologies can still play an important role. These lessons offer insights into the development of solar-based lighting markets in other regions, such as Sub-Saharan Africa, where grid extension continues but grid electricity remains intermittent in supply.

Off-grids such as solar micro-grids offer a sustainable solution in providing universal energy access. However, the literature points out that services gained rather than energy access through any technology matter to people. Using capability approach, this study focuses on understanding the role of solar micro-grids in improving the well-being of rural communities in India. The findings indicate that solar micro-grids play an important part in expanding people's choices and opportunities. Women appear to have benefited through assistance in household chores and reduced drudgery, while men seem to value entertainment and socialisation aspects. However, these energy-related capabilities are, to an extent, defined by socio-economic identities such as gender roles, and certain biases can get reinforced due to the social norms and traditions of the society. The study thus recommends that energy interventions need to be designed keeping in touch with local values and realities, thus, helping policies to be more effective. [ABSTRACT FROM AUTHOR]

In the remote communities of India, government policies have allowed for an increase in the share of solar energy-based technologies used by consumers, making the low-income households in these areas an emerging market for decentralized energy distribution. Despite the policies and involvement of both public and private energy developers, this market has not seen significant expansion in the last decade. Development is plagued by improper promotion strategies, incoherent financial models, and unpredictable markets. These missteps have fostered a negative perception of the technologies, which has a direct effect on low-income households and their ability to purchase renewable energy, impeding expansion of the energy sector. Decentralized solar energy technologies can serve as a major energy provider, but energy market developers have been tapping the wrong energy markets, leading to misappropriation of such technologies. This article explores the concept of energy poverty, with emphasis on solar energy markets and their potential to address the energy crisis in remote communities. It reviews the challenges and opportunities in this sector and suggests methods to accelerate their development. [ABSTRACT FROM AUTHOR]

In the last decade India has seen an increase in the adoption of solar energy‐based technologies by consumers, which has been supported by various government efforts and policies. The rural areas and low‐income households that lack a proper electricity supply have emerged as a market for solar off‐grid technologies, with private developers increasing their market base slowly in this group. This has promulgated the need to restructure the decentralized energy sector. Existing literature points out the suitability of solar off‐grid in such markets; the present study investigates the challenges that have hindered its growth. The study reviews the concept of poverty with respect to the energy sector and analyzes methods of determining poor energy access in the present scenario. It emphasizes the need to understand and reconceptualize policy instruments in order to make solar off‐grid a powerful tool in tackling energy demand and providing adequate energy access. It further explores the causes of energy disconnects and how grid‐independent solar energy is a technological solution of utmost relevance and in consonance with the idea of sustainable development. For a successful venture, both consumer behavior and marketer objectives are important determinants. The work also provides insights into various models, tools, factors, and social constructs that affect consumer perception and subsequently demand. Over the course of the study, it has been revealed how private players and entrepreneurs are tapping the wrong solar market, leading to misappropriation of solar energy technologies. The suggested improvements and recommendations of the present study from the analysis can serve as a guide for policy makers, technological innovators, and financial stakeholders.

Mini grids are increasingly filling the supply gap between government supplied electricity and the requirements of households and enterprises. We present a descriptive analysis of enterprise development within a large mini grid based rural electrification initiative launched in India in 2015. Using data from two surveys conducted with 229 enterprise operators, we explore the change in aspirations among enterprise owners and the impacts of longer duration of reliable electricity on key business outcomes. We find that improved quality of electricity from mini grids leads to a shift towards using mini grids as the primary source of electricity; transition from lighting to productive uses of electricity; and increased aspirational demand for electricity among enterprise operators. Further, we find a positive relationship between increased hours of reliable electricity supply and extended hours of operation and customer footfall, but not with revenue generation. Our findings suggest that mini grids offer an important opportunity for enhancing local aspirations for business development and should be an integral part of policies focused on rural enterprise development. • We surveyed 229 enterprises connected to solar mini-grids in September 2016 and June 2018. • Enterprises shift towards using mini grid electricity as their primary source. • Enterprises adopt more productive loads over time and reveal an increase in aspirational demand for electricity. • Longer duration of reliable power is correlated with increased operational hours and customer footfall, but not revenue. • Mini grids can benefit enterprise development by increasing aspirations and allowing experimentation with business.

Summary Although policy entrepreneurship is essential for fostering policy innovations to achieve sustainable development, the literature has conflated different types of entrepreneurship and disaggregated it using inconsistent terminology. We conceptualize entrepreneurship using a six‐stream variant of the multiple streams framework (MSF)—which addresses key limitations of the original MSF—to examine entrepreneurial activities in the case of the Jyotigram Yojana, a widely recognized policy innovation for managing the energy–water nexus in Gujarat, India. We find that whereas policy and political entrepreneurship no doubt played a significant role in coupling the streams and fostering this policy innovation, the process broker, program champion, and technology innovator were also important in policy formulation, implementation, and "success." We conclude that the six‐stream variant of MSF is useful for identifying and distinguishing various types of entrepreneurship involved in policy innovation for sustainability. [ABSTRACT FROM AUTHOR]

This study identifies and assesses the perspectives of four key stakeholder groups towards solar minigrids in rural India. The stakeholders considered are policymakers, minigrid developers and operators, development organizations, and national grid representatives. Recent state and national policies in India have increased the focus on minigrids and their services. In this study, stakeholder interviews were employed to identify the attitudes towards the recent electricity policy, the underlying context for minigrid development, the role of minigrids in rural electrification, and the inclusion of minigrid systems within the larger framework of electricity sector policies by the recent government minigrid policies. Results indicate that stakeholders agree that minigrids, as a rural electricity service, are currently viable to complement the national grid due to their high reliability, performance in remote regions, and diminishing cost per unit. However, stakeholders disagree on the future outcomes, with diverging views on the priority of minigrids as an electrification tool in the face of the expanding central grid, the ideal implementation strategy for minigrids, and the potential for grid‐minigrid interaction. Based on stakeholder feedback, the growth of minigrids in India is likely to be constrained by the confidence in recent policies, necessitating more frequent dialogue among decision makers and a solidified relationship to the national electricity grid.

Abstract Decentralised Solar Home Systems (SHSs) are established as an effective strategy to connect the 'last mile' without electricity access and leapfrog communities to clean energy solutions. According to the World Bank, the Pay-As-You-Go (PAYG) model has emerged as one of the effective commercially viable solutions to provide decentralised energy access to rural and remote communities in developing nations. The paying ability of households is a critical challenge for energy enterprises, and PAYG, with its easy payment schemes makes solar units affordable and allows households to gradually own these systems. The model also offers user training, ongoing maintenance, and service blocking functionality that minimises investment risk. The PAYG model has demonstrated huge success in Sub-Saharan Africa where Kenya pioneered the model as a cost competitive modern alternative for kerosene. One in five people in India lack access to electricity, and grid-connected rural communities often face frequent blackouts. With the advancement in distributed solar technologies and growing penetration of the mobile telecommunications network in India, PAYG could advance into a successful model to electrify communities living off the grid. Our analysis involves a two-dimensional approach where a systematic review of PAYG literature including case studies from Kenya and India was performed, followed by three expert interviews to further augment learnings and opportunities to deploy PAYG SHSs in India. This analysis finds that India's socio-political context seems suited for increased PAYG penetration, including utilising the opportunity provided by the country's Unified Payments Interface. This paper offers insights for practitioners and policymakers to consider the PAYG model to deploy clean electricity to households and rural micro-enterprises. Highlights • Lessons for successful implementation of PAYG energy model in India • Superior products and maintenance mechanisms are integrated into PAYG. • PAYG financing appropriate for energy budgets of poor households. • India's Unified Payments Interface presents a unique opportunity for PAYG model.

Rural electrification has progressed unevenly across the world since 1945, with some rural communities gaining access to power decades earlier than others. We examine the association between early electrification and the quality of electricity service to households, testing the hypothesis that aging infrastructure compromises the quality of electricity service. Using the 2014–2015 ACCESS survey from rural India, we find that early electrification is associated with improvements in the quality of electricity service, even controlling for village size and distance to nearest town. A possible explanation for the finding is that early electrification generates economic gains that allow the rural community to invest in maintenance and upgrades. [ABSTRACT FROM AUTHOR]

Subjective satisfaction is a central element of technology adoption, but scholars have not analyzed the determinants of households' satisfaction with their cooking arrangements. Drawing on an original survey of 8568 households across six Indian states, we uncover the predictors of such satisfaction. Households do not find firewood collection inconvenient, but they are dissatisfied if they have to travel long distance to purchase firewood. Among sub-components of subjective satisfaction, reduction in smoke, speed of cooking, and quality of meals dominate over others (difficulty, cost, and safety). Moreover, we identify access to LPG – a modern cooking fuel – as a strong and robust predictor of high subjective satisfaction, mostly through reduction in smoke and increase in speed of cooking. Rural households ascribe a lot of value to access modern cooking fuels that reduce indoor air pollution, and beneficiaries of interventions to improve such access would value it. Thus, efforts to reduce reliance on cooking with traditional biomass are not just paternalistic top-down interventions but contribute to significantly improve households' satisfaction with their cooking arrangements.

Although most studies of energy poverty focus on whether or not households have access to modern fuels, expenditure is also an important issue, as households in developing countries spend a significant proportion of their total expenditures on energy. Using nationally representative household data from India, 1987–2010, this article describes and explains trends in household energy expenditure. While monthly household spending on energy has increased in many Indian states, this change is not driven by increased household affluence. Statistical analysis shows that when modern fuels (LPG for cooking, electricity for lighting and appliances) are available, households are willing and able to spend on energy. Indian households that have seen improved access to LPG and electricity have also seen much higher energy expenditures, whereas increased household incomes do not explain greater spending on household energy. For policymakers, the key lesson is that programs to improve access to modern fuels allow both wealthy and poor households to spend money on valuable energy services. [ABSTRACT FROM AUTHOR]

India is a country where 300 million people still live without access to formal electricity, and where hundreds of millions more live with irregular supply through the existing grid network. This paper examines business innovation in the diffusion of off-grid solar technologies in India. An in-country survey of off-grid solar energy providers from across the nation was conducted and coupled with extensive field interviews. Findings reveal that most off-grid solar energy enterprises are not operating in the government subsidy market and that more than half are not offering any form of financing to their customers when selling their products. Also, more than half of the enterprises are selling their products in areas where the electric grid is present. Analysis of data collected suggests that an increase in product categories (lanterns, solar home lighting systems (SHS), micro-grids, etc.) negatively affects unit scaling for a firm but increases the likelihood that the firm is offering financing for its products. In areas without the electricity grid, the number of off-grid solar technology options decreases because the firms operating in the area have fewer categories of technology options. This study finds that off-grid solar technology enterprises that focus on fewer technology categories are more likely to achieve unit scaling. This finding must be balanced with the fact that the extent of the grid has not inhibited the market for off-grid solar technologies, but rather affects the number of categories of technologies that can be offered in those regions. Development programs should thus recognize that those who need electricity access the most may be the ones with the most limited technology options. [ABSTRACT FROM AUTHOR]

• Despite widespread cooking gas availability and use, biomass use for cooking and heating remains prevalent in six energy poor north Indian states. • We observe wide variations in the way households with the same primary and secondary cooking fuels use their secondary fuels. • About 40% of rural and urban slum households used biomass for some non-cooking energy end uses, especially space heating and heating bath water. • Three-quarters of fuel stackers reported switching their primary cooking fuel across seasons of the year. • Detailed surveys of household cooking fuel end use offer insights into the important roles played by biomass in households. Expanding the use of clean cooking fuels has been a priority for the Government of India in recent years to obtain potential public health and women's empowerment benefits. Evidence to date suggests most recent clean fuel adopters continue to use polluting biomass for some household energy needs. However, the specific ways households use both polluting and clean fuels together, known as fuel stacking, is not fully understood. We use survey data from 2,765 households in rural communities and urban slums in six north Indian states to detail fuel stacking practices. Half of rural and one-third of urban slum households stacked a clean and polluting fuel together. We classify stackers into four groups based on their reported primary and secondary fuels (e.g., primary gas and secondary firewood). We observe significant variations in the intensity of secondary fuel use among households in the same stacking group. Across all stackers, about half use their secondary fuel daily, while about one-fifth use it less than once per week. Non-cooking energy needs, like space and water heating, motivates 40% of biomass users to use polluting fuels. Seasonality is another important consideration as 75% of fuel stackers reported switching their primary fuel across seasons of the year, with nearly 90% primarily using gas during the rainy season. Our results highlight considerable heterogeneity in fuel use behaviors among households in the same stacking category. We also underscore that cooking gas is popular and able to meet all cooking needs, but it is important to consider the use of biomass for non-cooking tasks to enable a complete transition to clean cooking fuels. These results signify the need for more nuanced fuel stacking information in policy design and program evaluation. [ABSTRACT FROM AUTHOR]

India faces a formidable challenge in ensuring security of access to modern energy carriers to majority of its population. The fossil-fuel dominated centralized energy system has proved to be ineffective in creating sustainable access to energy, which suggests need for a radical and innovative approach. We present such an approach. First, the need for innovations given the implications of lack of energy access on sustainable development is assessed. Next, possible innovations with respect to technologies, policies, institutions, markets, financial instruments and business models are discussed. Finally, an economic and financial feasibility of implementing such innovations are analyzed. The results indicate that such a proposal needs an investment of US$ 26.2 billion over a period of 20 years for a GHG mitigation potential of 213Tg CO2e. The proposition is profitable for the enterprises with IRRs in the range of 39%-66%. The households will get lifeline access to electricity and gas for cooking at an affordable monthly cost of about US$ 5.7. [ABSTRACT FROM AUTHOR]

While solar home systems hold considerable promise for improving access to electricity in developing countries in tropical regions, scholars and practitioners argue that the lack of awareness, interest, and ability to pay for the technology undermines the growth of the market. We describe and explain patterns of awareness and interest in solar home systems (SHS) in a survey of 760 respondents in rural Uttar Pradesh, India. We conducted the surveys in collaboration with a local solar enterprise, Boond, and chose villages that are prime locations for the installation of solar home systems. We found that high household income and education levels, as well as young age, predict awareness of SHS products. In addition to wealthy and educated households, willingness to pay is higher in households that have electricity. The findings can help policymakers identify and target households with low levels of awareness and solar entrepreneurs identify suitable customers for their products. [ABSTRACT FROM AUTHOR]

Rapid urbanization in the developing world underscores the policy challenge of urban energy poverty. This article investigates patterns of energy poverty in Patna, the capital of the state of Bihar in India. Informed by the field research, our emphasis is on inadequate lighting among street vendors. A survey of 1000 street vendors in the metropolitan area reveals high levels of energy poverty, with vendors being forced to choose between inadequate lighting and expensive power from diesel generators operated by local entrepreneurs. The survey also shows that vendors consider improved lighting a top priority and believe that improved lighting could expand their business and attract customers. While vendors are generally aware of solar panels, a few are using this technology in the marketplaces. The results reveal the need for new policy interventions that either promote grid access for the informal economy or seek new alternatives, such as solar lighting, to diesel generators.

Abstract: Most studies on household energy choices have considered income and education as suitable proxies for socio-cultural contexts, primarily because the available data on household energy is from census surveys which are mainly household consumption surveys, not focused energy surveys. Acknowledging the existing data constraints, a more focussed household energy survey was designed for rural India with the aim of better understanding determinants of current energy use patterns, energy choices, to measure the impacts of these factors, and importantly, arrive at key policy insights. This paper revisits the definition of access to include for reliability and quality going beyond conventional understanding. It also relooks at the role of gender in household energy choices. Having established that apart from income, socio-cultural factors may have a greater role in determining household energy choices, the model results indicate electricity access would have a positive impact on cooking energy choices only after meeting a minimum threshold requirement. As women move towards more formal employment, the odds of choosing cleaner fuels increase significantly. Thus, while macro-policies may provide important guidelines and the necessary framework, implementation strategies need to be designed at the local level through a participatory approach making energy an integral part of the development paradigm.

Abstract: In many developing countries, the national electricity grid fails to provide rural communities with a reliable supply of electricity. Given the high socio-economic cost of this policy failure, both scholars and policymakers have recently become interested in off-grid electrification programs. However, the relationship between national grid expansion and off-grid electrification remains unclear. Are these two approaches independent of each other, or perhaps even competitors? This article develops a taxonomy that allows grid expansion and off-grid electrification to complement each other. Explicit policy integration is necessary to encourage investment in off-grid electrification and avoid duplication of effort. Otherwise, there is a danger that the poorest and geographically most remote segments of the rural population could be left outside electrification efforts. As an illustration, the article offers a case study of India. [Copyright &y& Elsevier]

Abstract: India’s rural energy challenges are formidable with the presence of majority energy poor. In 2005, out of a rural population of 809 million, 364 million lacked access to electricity and 726 million to modern cooking fuels. This indicates low effectiveness of government policies and programs of the past, and need for a more effective approach to bridge this gap. However, before the government can address this challenge, it is essential that it gain a deeper insight into prevailing status of energy access and reasons for such outcomes. Toward this, we perform a critical analysis of the dynamics of energy access status with respect to time, income and regions, and present the results as possible indicators of effectiveness of policies/programmes. Results indicate that energy deprivations are highest for poorest households with 93% depending on biomass for cooking and 62% lacking access to electricity. The annual growth rates in expansion in energy access are gradually declining from double digit growth rates experienced 10 years back to just around 4% in recent years. Regional variations indicate, on an average, cooking access levels were 5.3 times higher in top five states compared to bottom five states whereas this ratio was 3.4 for electricity access.

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.

Solar lamps are a quick, affordable, and effective way to provide basic lighting for households in rural areas of developing countries. However, implementers and researchers argue that the market for solar products is hampered by a lack of awareness and willingness to pay (WTP) for solar technology. In this paper, we investigate awareness of solar products, household motivation to adopt solar technology, household perception of solar lamps when compared to kerosene-based lighting devices, and lastly, the availability of electricity after dark. We analyzed a repeated-measures (longitudinal) data of 1159 rural households in energy-poor villages in the states of Bihar, Jharkhand, and Uttar Pradesh, India. Longitudinal logistic regression analyses were performed to study how various factors influence users WTP for solar lamps at Indian market price (~8.61 US$) over time. We find that households awareness of various solar products and their motivation to adopt solar technology has increased over time but there is much room to grow awareness in Bihar, Jharkhand and Uttar Pradesh, especially for solar home systems and solar water pumps. Our model predicted that the households WTP for solar lamps at the market price increased with high income but it is significantly moderated by their level of awareness of solar products and their motivation to adopt solar technology. These findings suggest that increasing awareness of solar products through various dissemination programs leading to significant interest in solar products among people which in turn may enhance their WTP for solar products. • Repeated-measures (longitudinal) data of 1159 rural households in energy-poor villages in India were analyzed. • This study determines factors that influence the households willingness to pay (WTP) for solar lamps in rural India. • Awareness of solar products coupled with motivation to adopt solar technology significantly raise the probability of WTP. • WTP for solar lamps at the market price increases with income. • Awareness of solar products through various programs lead to significant interest in solar energy products among people.

The transition to sustainable energy requires an assessment of drivers of the use of clean and dirty fuels for cooking. Literature highlights the importance of access to clean fuel for switching from dirty fuels to clean fuels. Though access to cleaner fuels, such as electricity promotes clean fuel use, it does not necessarily lead to a complete transition to the use of clean fuels. Households continue using traditional fuels in addition to the clean fuels. The main objective of this paper is to explain the choice of dirty cooking fuels even when access to electricity is provided. We use nationally representative household survey data to study the household energy use decisions in three middle-income countries, namely, India, Kazakhstan, and the Kyrgyz Republic. The study discusses the role of access to natural gas, free fuel, convenience or multi-use of fuels featured by the heating system installed, built-in environment, and other socio-economic factors in household fuel choice for cooking. The results show that access to natural gas increases the likelihood of opting for clean fuel, while the availability of free fuel in rural areas and the coal-based heating system promote the use of solid fuels., (Copyright © 2021 Elsevier Ltd.

As developing countries ramp up efforts to secure adequate rural electrification, mini-grids are growing in popularity. However, a key barrier for their widespread deployment remains the inherent uncertainty around revenue and project sustainability. To address these concerns, preliminary energy-use surveys that assess the suitability of a site for mini-grid installation should be utilized. Energy-use surveys account for village demography, current and projected demand and willingness to pay, amongst other parameters. This study presents a preliminary quantitative and qualitative methodology for evaluating the suitability of a rural village for the installation of a mini-grid. The framework may be used by energy service companies and project managers prior to selecting a site for a mini-grid. [ABSTRACT FROM AUTHOR]

Many rural households in India lack access to reliable energy services but off-grid solar technologies are able to meet basic lighting and electricity needs. The availability and perception of different technologies, appliances, and services influences how households will transition to renewable energy. To identify factors that affect household decisions among various energy sources, this paper examines purchase and use patterns for electricity sources and basic end-uses for twenty-two households in three rural villages in Jharkhand, India using a qualitative, card-based interview protocol. This paper examines energy stacking or the use of multiple fuel sources to meet household energy needs. Results indicate that households use multiple energy sources to meet basic lighting and charging needs, but these patterns vary across households. Adoption of lighting technologies were influenced by a range of factors, with pricing and payment options influencing 88% of solar lantern purchases and 75% of solar home system purchases. In contrast, decisions to connect to the solar microgrid were more heavily influenced by awareness of the technology. Retention of existing lighting options stems from three factors access or availability, capacity, and quality of new lighting additions – with capacity being the most commonly referenced across kerosene, solar lanterns, and solar home systems. This paper argues that different factors influence adoption and retention of household lighting sources with key interdependencies across sources resulting the need for new, or to retain existing, lighting options. • All 22 households stack or retain multiple technologies over time. • Households on the state-provided grid frequently purchased backup sources of lighting after grid access. • Microgrid households use fewer appliances compared to grid-connected households. • Adoption of new technology was often influenced by awareness, pricing, and access. • Retention of sources was influenced by quality, end-uses, and access to repair services.
