Abstract:
Household transitions to cleaner cooking fuels (for example, liquefied petroleum gas (LPG)) have historically been studied
from a demand perspective, with clean energy usage expected to increase with improvements in household socio-economic
status. Although recent studies demonstrate the importance of supply-side determinants in increasing clean cooking, few
large-scale studies have assessed their importance quantitatively, relative to demand-related factors. Here, as part of the
CLEAN-Air(Africa) study, we examine a population-based survey (n= 5,638) of cooking practices in peri-urban communi ties within Cameroon, Kenya and Ghana. Multilevel logistic and log-linear regression assessed the demand and supply-side
determinants of LPG usage (primary versus secondary fuel) and consumption (kilograms per capita per year), respectively.
Supply-side factors (for example, cylinder refill and transportation costs) and the use of single versus multiburner stoves were
better predictors than household socio-economic status for both the probability of primarily cooking with LPG and the annual
LPG consumption. These results highlight the need for policies that promote LPG supply and stove equipment to meet house hold n
