A large population living in developing and under-developed does not have access to clean domestic energy, in particular, electricity and cooking gas, leading to energy poverty. Many countries around the world are putting efforts to provide clean domestic energy through various schemes by either providing improved cookstove design or LPG cooking stoves. A large population in India still uses conventional biomass-based cooking methods resulting in environmental and health issues. Implementation of the "Pradhan Mantri Ujjwala Yojana (PMUY)," in India, to distribute 50 million gas cylinders to below poverty line (BPL) women increased the LPG penetration in India. India is the world's second-largest LPG consumer. The cumulative annual growth rate of LPG consumers in India is 15%, presented in Fig. 1. It is expected to grow with the increasing population in the country. LPG penetration in India is presented in Fig. 2. Indian rural population is largely moving towards the use of LPG gas stoves from biomass-based domestic cooking. Socio-economic factors, Pradhan Mantri Ujjwala Yojana (PMUY), education, and awareness are the motivators for increasing the use of LPG in rural India. With such a large scale of use, improvement in the fuel consumption of LPG cookstoves will have a huge impact on fuel savings and economy.
