Abstract
We conduct an experiment studying adoption of an induction stove manufactured by ECOA (formerly Burn Manufacturing) by households in Kenya currently using a charcoal stove. Purchase of an induction stove also includes three induction pots. The induction stove has a power rating of 200W--2000W depending on the desired functionality (from low simmer to high boil) and a voltage rating of 240--250VAC and 50--60Hz. Between 12 August and 19 September 2025 study enumerators enrolled into the study 2,511 people residing in the urban and peri-urban areas around the cities of Naivasha, Gilgil, and Nakuru in Nakuru county in Kenya. Respondents were enrolled by enumerators walking around the study areas. Respondents who consented to participate in the study completed a short survey consisting of demographic and socioeconomic questions. Barring financial and logistical constraints, our plan is to re-visit each household again one month after enrolment for a Visit 2 and then again one month later for Visit 3.
