Data and Code for: Credit, attention, and externalities in the adoption of energy efficient technologies by low-income household

We study an energy efficient charcoal cookstove in an experiment with 1,000 households in Nairobi. We estimate a 39% reduction in charcoal spending, which matches engineering estimates, generating a 295% annual return. Despite fuel savings of $237 over the stove’s two-year lifespan—and $295 in emissions reductions—households are only willing to pay $12. Drawing attention to energy savings does not increase demand. However, a loan more than doubles WTP: credit constraints prevent adoption of privately optimal technologies. Energy efficient technologies could drive sustainable development by slowing greenhouse emissions while saving households money.
