The officer added: “For example, during Raksha Bandhan, the celebration will be encouraged by taking a pledge to save trees by tying a rakhi to trees and pledging to protect them, Christmas, will be an occasion for energy soldiers to sing energy carols, Ganesh Utsav will be celebrated by energy soldiers to popularise the use of small recyclable Ganesh idols rather than that of large plaster of paris idols that are normally used, along with their immersion at home in the bucket to protect the lakes.”
