Energy consumption lost brick by brick: IIT study

by

A new study by researchers from severalIndian Institutes of Technology(IITs), including Hyderabad, and other organisations has revealed energy consumption discrepancies in the Indian brick . They have analysed energy conservation in brick production.Telanganaproduces 3% andAndhra Pradesh4% of Indias bricks. The study, Reconciliation of Energy Use Disparities in Brick Production in India, has been published in Nature.

Highlighting the significance of energy conservation in achieving carbon neutrality in the building sector, the study shows that current energy consumption estimates in the brick industry were vastly underestimated,

comparable to that of steel and cement industries. Researchers, including Azharuddin Hashmi and Asif Qureshi from IIT-H, had modelled Indian brick production and regional energy consumption by combining a nationwide questionnaire survey and remote sensing data on kiln enumeration.

States in the west and east are responsible for 10% and 8% production (of bricks). The contributions from the north and North-East are meagre. This implies that the operational practices in the Indo-Gangetic plain and the peninsula have the largest influence on national energy consumption.
