Adoption of innovative energy efficiency pots to enhance sustained use of clean cooking with gas in resource-poor households in Kenya: Perceptions from participants of a randomized controlled trial

Background: Scaling up clean cooking is a priority to address the substantial health burden from exposure to household air pollution resulting from burning of polluting fuels. The costs of cooking equipment and fuel, as well as cooking behaviors, may present barriers to adoption and sustained use of clean cooking. This paper reports novel qualitative findings from a Randomized Controlled Trial (RCT) evaluating the effects of innovative energy-efficient cooking pots on sustained use of LPG for the first time in a low and middle-income setting. Method: Semi-structured interviews (SSIs) were conducted with 22 of 200 cooks (LPG primary users) from an informal settlement in Nairobi, participating in the RCT. Data were analysed through thematic analysis. Results: Reported benefits of the enhanced pots (compared to standard pots), included perceived fuel and time savings and prestige. Findings also indicate participants' willingness to pay for the pots and ways to support their scale. Conclusion: This study highlights the potential for energy-efficient pots in facilitating sustained/exclusive clean cooking with LPG and their ability to meet all cooking needs. This is relevant to informing commercial scalability of energy-efficient cookware in the local Kenyan market

Pay-as-you-go liquefied petroleum gas supports sustainable clean cooking in Kenyan informal urban settlement during COVID-19 lockdown

Approximately 2.8 billion people rely on polluting fuels (e.g. wood, kerosene) for cooking. With affordability being a key access barrier to clean cooking fuels, such as liquefied petroleum gas (LPG), pay-as-you-go (PAYG) LPG smart meter technology may help resource-poor households adopt LPG by allowing incremental fuel payments. To understand the potential for PAYG LPG to facilitate clean cooking, objective evaluations of customers’ cooking and spending patterns are needed. This study uses novel smart meter data collected between January 2018-June 2020, spanning COVID-19 lockdown, from 426 PAYG LPG customers living in an informal settlement in Nairobi, Kenya to evaluate stove usage (e.g. cooking events/day, cooking event length). Seven semi-structured interviews were conducted in August 2020 to provide context for potential changes in cooking behaviours during lockdown. Using stove monitoring data, objective comparisons of cooking patterns are made with households using purchased 6 kg cylinder LPG in peri-urban Eldoret, Kenya. In Nairobi, 95% of study households continued using PAYG LPG during COVID-19 lockdown, with consumption increasing from 0.97 to 1.22 kg/capita/month. Daily cooking event frequency also increased by 60% (1.07 to 1.72 events/day). In contrast, average days/month using LPG declined by 75% during lockdown (17 to four days) among seven households purchasing 6 kg cylinder LPG in Eldoret. Interviewed customers reported benefits of PAYG LPG beyond fuel affordability, including safety, time savings and cylinder delivery. In the first study assessing PAYG LPG cooking patterns, LPG use was sustained despite a COVID-19 lockdown, illustrating how PAYG smart meter technology may help foster clean cooking access
