You may want to ask how we save our energies. These are following steps of how we save it : 1. Computer-  The average usage of computer by us a day is about 4-5hrs before this project. But now we use it only for 20-30mins , and instead of play computer games , we play outdoor games such as basketball and soccer. 2.Air - condition- We cut down our usage on air-condition from 7hrs to 45mins. Same , we switch it on for 45mins mins(only at night) and the rest in replaced by fan. We can do it so can you!
