Watercare said ways to reduce wastage include finding and fixing leaks, showering for a less amount of time and washing full loads of laundry.

This reduces wastage, with 92% of the total energy in the gas converted into heat or electricity.

Investment in technology, better transport and storage for India's vast agriculture sector could also help dampen supply-side inflation pressures by reducing wastage.
