Gasoline from Crude Petroleum.
So, the price per barrel is at about $70/barrel. This means the cost of the gasoline is around $1.67 gallon. Of course, this assumes the entire $70 goes to obtain the gasoline and nothing else. This does not account for the actual costs of refining, transportation, and distribution to market. Of course, this doesn't include the taxes!
Here in Wisconsin we pay 49.5 cents/gallon (fourth highest in the nation) so for those of us in WI we are looking at 2.165. This leaves about 68 cents/gallon (current gas goes for $2.85/gallon up here) for profit (yes, businesses are in business to make a profit), transportation, refining, and distribution. I can not see or believe any of those are very cheap (except for the profit part) as the transportation, refining, and distribution all requireenergy to carry out. Of course, you have at least two layers of middlemen in the process taking their cut.
