We all have been here. We are complaining about gas prices these days. I can still remember when, as recent as a decade ago, the gas prices were between $1.00 and $2.00 per gallon. Now we pay around $3.00-3.50  a gallon in the northeast. I drive an SUV and it costs me $80 to fill up my gas tank. However, I think the gas prices are relatively low. In spring 2012, I took “VAST 270: Energy Resources and Tech” taught by Prof. Hornfeck (yes, VAST 203 is my second VAST course) and I can recall Prof. Hornfeck saying that our gas prices are actually low, considering the high demand for gas resulting in a major shortage. I believe that higher gas prices would deter larger number of people from continuously getting gas and get them to use a more efficient form of transportation (public transportation, bicycle, walk…). In Europe, while public transportation system is very good, the fuel prices are expensive. € 1.50 per liter, which is equivalent to $7.75 per gallon.
