Variation in rural household energy transitions for basic lighting in India.

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.
