Fuels are the liquid substances which are used for burning woods and running vehicles. We should conserve fuel because it is used for running vehicles, for burning woods in winter, for cooking food, for running industries, for lighting the house (meaning:-in some areas there isn't electricity so the people use kerosene for producing electricity) and so on. We can conserve it by keeping it away from children, by using in limited amount, by not wasting it on unusual activities, by putting it in a sealed utensil and so on. !!!THANKS!!! ♡♥♧COMMENTS PLZ♣☆★
