A new methodology to find out cooking energy needs for a rural household.

In the era of global warming and ever rising energy demand, climate justice has become the need of the hour. Sustainable solution has become the key to the success for environment. The cooking sector is considered as one of the major energy consuming sectors in developing and underdeveloped countries. Inherently, associated hazardous effects and energy inefficiencies of conventional biomass cooking system forces unconventional cooking energy to become popular day by day. In this study, a new census based approach is being presented to find out cooking energy requirement of a single rural household of India. Mathematical modelling is being done while scrutinising coke, firewood and chips, coal, and LPG as cooking fuel and by eliminating charcoal, petrol, diesel and kerosene. Exact heat energy required per household per meal has been achieved 4,212.02 kJ. Out of which vaporisation of water, heating food to boiling temperature and convection losses from vessels shares 1,474.21 kJ, 842.40 kJ and 1,895.41 kJ respectively. The outcome of this study can serve a baseline for inventors, researchers and policymakers of micro-scale unconventional/solar cooker. [ABSTRACT FROM AUTHOR]
