Abstract/Summary

India aims to reduce pollution from solid residential fuel use and promote clean energy through the Pradhan Mantri Ujjwala Yojana (PMUY) scheme launched in 2016. The scheme targeted below-poverty-line (BPL) families using traditional stoves by providing free LPG connections. BPL families in urban slums and village dwellers of Delhi are major users of solid residential fuel. This study investigates the overlying reasons by surveying ∼6500 households from ∼700 urban slums and villages and identifying high consumption areas and fuel use patterns. The urban slums and villages of Delhi reported a total usage of 0.415 Mt. residential fuels annually for the year 2019 (72 % fuelwood, 27 % dung cake, 0.002 % crop residue, and 0.001 % coal). An interrelation of household energy consumption patterns, socio-economic demographics, and kitchen characteristics is also presented in the study. The energy-ladder hypothesis was found to be validated in slums while the linearity of the hypothesis was contradicted in rural areas as the use of traditional stoves was driven by food preferences rather than economic constraints. Predictive models were developed to estimate residential fuel usage for space heating and water heating during winters, which are not reported by NSSO annual reports. The study also calculated the gross calorific values of biomass fuels to assess their energy content. This information aids in further understanding biomass combustion efficiency and the importance of transitioning to cleaner energy sources like LPG for sustainable practices. This study estimated an additional annual $10.04 million in Government aid is sufficient to minimize pollutant load emanating from residential fuel combustion by providing free LPG refills to economically weaker households. This action has the potential to reduce residential fuel usage for cooking significantly leading to a decrease in pollution levels across the megacity.
