Drive Less or Carpool: By driving less you are not only saving fuel but also helping in reducing global warming. Also, look out for other possibilities, for e.g.: car pooling. If you have colleagues who live in the same area then you can combine trips. If you need to go to a local market then either walk or go by cycle. Both of them are great form of exercise. The biggest pollution emitting fumes are caused by oil and gasoline. Cutting down consumption, is a huge step to reducing energy wastes.
