The first step in saving energy is to bring your own bags. This means that you reduce the amount of plastic consumed. Plastic bags are made of petroleum products which are an important and rare fossil fuel. Cloth bags are a good option, especially when you are grocery shopping. These bags are durable and reusable.

If you do have to take a bag, ask for a paper bag instead of a plastic one. Paper is easier to recycle than plastic and therefore an eco friendly option.
