Abstract
To reduce carbon emissions and mitigate climate change, many countries are adopting electrification policies to encourage consumers to shift from burning fossil fuels. In Nepal, where electricity generation is mostly hydropower and therefore associated with low levels of GHG emissions, the government is encouraging consumers to adopt electric cooking. Little evidence exists, however, as to how best to do so. Even less is known regarding how electric cookstove adoption affects energy use and electricity consumption. This randomized experiment in Kathmandu, Nepal provides evidence on the two lines of inquiry.

To address the first, the RCT will experimentally tests methods of increasing adoption: subsidies for electric stoves and the associated cookware, information on the recurring costs of stove use, and details on the pollution and health effects of cooking.

To address the second, we will use the experimentally-induced variation in adoption to estimate the effects on energy use and electricity consumption.

Interventions

Intervention(s)
This randomized experiment, which is conducted in Kathmandu, Nepal, provides experimental evidence on electric cooking. The RCT will experimentally vary different interventions designed to increase adoption: subsidies for electric stoves and the associated cookware, information on the recurring costs of electric stove use, and information on the pollution and health effects of cooking. The study will use the experimentally-induced variation in adoption to estimate the effects on energy use and electricity consumption.

Experimental Design

Experimental Design
The RCT will experimentally vary different interventions designed to increase adoption: subsidies for electric stoves and the associated cookware, information on the recurring costs of electric stove use, and information on the pollution and health effects of cooking. The study will use the experimentally-induced variation in adoption to estimate the effects on energy use and electricity consumption.
Experimental Design Details
Of households surveyed in mid-2023, households are randomly assigned to one of the following information treatment groups:
I1: information on the cost of operating electric stoves
I2: information on the health benefits of electric cooking
I3: no information (control group).

Then coupons providing subsidies that can be used to purchase electric cookstoves (or the pots/pans specific to electric induction stoves) are cross-randomized, as follows:
S1: Higher subsidy (3,000 NPR)
S2: Lower subsidy (1,000 NPR)
S3: No subsidy (control)

The cross-randomization results in 9 groups of differing treatments:
1     High subsidy-cost info      
2     low subsidy-cost info       
3     no subsidy-cost info      
4     High subsidy-health info    
5     low subsidy-health info       
6     no subsidy-health info        
7     High subsidy-no info       
8     low subsidy-no info         
9     no subsidy-no info
