The Southern India Engineering Manufacturers' Association has mooted a project to study energy efficiency of star-rated pumps in the agricultural sector.

Former president of the association Mahendra Ramdass said nearly 40 per cent energy saving can be achieved by replacing the old agricultural pumpsets with Bureau of Energy Efficiency (BEE)- rated energy efficient pumpsets. In Tamil Nadu, there were some areas that still had 40-year-old pumps. These consumed a lot of energy.
