Abstract
Ninety-eight percent of households in Uganda rely on biomass and charcoal fuels for cooking. This heavy reliance on biomass fuels has negative effects on public health, women’s empowerment, and local and global environments. In response, the government of Uganda has made increasing access to electric cooking a national priority and targets 50% adoption by 2025. This study seeks to evaluate strategies to promote the use of electric cooking appliances. Specifically we aim to understand the usage of a highly efficient electric cooking appliance, the electric pressure cooker (EPC), in Ugandan households. Using a randomized experiment, we study how household energy use and cooking decisions are affected by changes in electricity prices and cooking energy use information.

Experimental Details

Interventions

Intervention(s)
This study involves two interventions. In the first, the rebate intervention, households receive a monthly cash transfer, via mobile money, calculated to simulate a lower average electricity tariff and based on each household’s total electricity consumption in the preceding month. In the second, the information intervention, households receive a text message informing them of the amount of electricity they consumed when using the electric pressure cooker (EPC) in the preceding month.

Primary Outcomes

Primary Outcomes (end points)
EPC cooking events per day, week, and month; electricity consumed by EPC (kilowatt-hours (kWh) per month); time spent using EPC (minutes per month); total household electricity consumption (kWh per month)

Experimental Design

Experimental Design
EPC purchasing households will be enrolled into the study at the time of purchase by the appliance distribution partner. At baseline enumerators will visit participant households to administer a short survey and install a smart meter to monitor EPC use. Households will be divided into four groups: 1 control and 3 treatment. The treatment groups will receive a rebate and/or information intervention, with one group receiving only the rebate treatment, one receiving only information, and one receiving both. In the rebate treatment, households receive a monthly cash transfer, via mobile money, calculated to simulate a lower average electricity tariff and based on each household’s total electricity consumption in the preceding month. In the information treatment, households receive a text message informing them of the amount of electricity they consumed when using the EPC in the preceding month.
