Professor E Somanathan and Dr. Farzana Afridi discuss ongoing work, aided by ASHA workers, on raising awareness about the detrimental health impacts of using solid fuels for cooking and the need for…
This paper reviews the experience of a for-profit firm in Rwanda promoting biomass pellets and a fan micro-gasification improved cookstove as a clean cooking alternative to charcoal. Consumers purchase locally produced biomass pellets and receive the improved cookstove on a lease basis. The cost of the pellets and stove(s) is lower than the cost of cooking with charcoal in the urban setting where our study takes place. Inyenyeri has been piloting its business model since 2012.
Exposure to household air pollution (HAP) from cooking and heating with solid fuels is major risk factor for morbidity and mortality in sub-Saharan Africa. Children under five are particularly at risk for acute lower respiratory infection. We use baseline data from randomized controlled trial evaluating a household energy intervention in Gisenyi, Rwanda to investigate the role of the microenvironment as a determinant of children's HAP-related health symptoms. Our sample includes 529 households, with 694 children under five.
Cooking with solid fuels and inefficient cookstoves has adverse consequences for health, environment, and human well-being. Despite the promise of improved cookstoves to reduce these impacts, adoption rates are relatively low. Using a 2-wave sample of 144 households from the baseline and first midline of an ongoing 4-year randomized controlled trial in Rwanda, we analyze the drivers and associations of early adoption of a household energy intervention marketed by a private sector firm.
Promoting access to clean household cooking energy is an important subject for policy making in low‐ and middle‐income countries, in light of urgent and global efforts to achieve universal energy access by 2030 (Sustainable Development Goal 7). In 2014, the World Health Organization issued “Guidelines for Indoor Air Quality: Household Fuel Combustion”, which recommended a shift to cleaner fuels rather than promotion of technologies that more efficiently combust solid fuels.
Discussions between policymakers about renewable energy have gained momentum in recent years, amid growing recognition of the need for more investment in green energy sources. The question is whether households in developing countries like South Africa will support green energy actions if it comes at an additional cost or whether they are simply arm-chair environmentalist. To assess this, we use the contingency valuation method (CVM) to identify the determinants of support for renewable energy.
South African households, like households in many other developing countries, are faced with regular power outages. This is a big problem, since the outages that the households experience are both frequent and long in duration. Efficient electricity infrastructure investment decisions are possible only if the welfare loss of electricity blackouts is determined. We estimate a measure for welfare analysis. We subject respondents to eight power outage scenarios. We use a random parameter panel Tobit model to account for both zero willingness to pay (WTP) and cross-sectional heterogeneity.
