I know most people will want to conserve their cooking gas. Well, one of the ways to save your cooking gas is simply to: Ensure that you use the right size of cooking pot. The width of your cooking pot should be the same as the width of the flame.
If the gas flame is on the side of the cooking pot, it means the pot is too small and much of the heat is being wasted. So, if using a small pot, make sure you turn down your gas cooker.
