Peak oil is the maximum point of oil in which everthing before it and after it is of less quantity or quality.
Okay, that is interesting.  Is that something we use?
 Some observers, such as petroleum industry experts Kenneth S. Deffeyes and Matthew Simmons, predicted there would be negative global economy effects after a post-peak production decline and subsequent oil price increase because of the continued dependence of most modern industrial transport, agricultural, and industrial systems on the low cost and high availability of the oil
That seems to make sense.  Is that why gas prices are on the rise?
no, the gas prices are high because of the companys wanting to make a large amount of profit
From what I recall, the price of oil is related to the price of gas, as well as supply and demand
The demand is high, but the supply isl arge too. especially when there are alternative such as natural gas storage.
