Data by market researcher GfK India showed the contribution by volume, or number of units sold, for energy saving ACs with four and five stars has moved from 14% in 2019 to 27% in 2023. But for a category like refrigerators, which wouldn’t inflate power bills as much as an air-conditioner would, the volume contribution of such models remains flat at 10%. Similarly, GfK data showed volume contribution of energyefficient inverter AC models climbed to 84% in 2023, from 61% in 2019, after manufacturers priced the new models on a par with the older, fixed-speed compressor variants.
