The price of gas in the future will depend on politics and price per barrel of oil. Seeing that the U.S. gets most of its oil from foreign oil companies, if a war was made the trade of oil will be in danger. When the price per barrel goes up so does the price of gas. Another way gas will go up is the less amount we have the more it will cost. Most things are priced on demand, the more demanding the more it will cost.
