Fuel prices have risen, again...and again...and again. They will likely continue to increase weekly, if not daily, as we continue to guzzle gallon after gallon to operate our motor vehicles each and every day. We continue to guzzle this fossil fuel as though the supply were endless, while, in actual fact, the supply is limited and will be exhausted much sooner than most of us want to think. As that supply decreases or the expense to make it available to us increases, the prices that we pay for that fuel will continue to rise beyond our control.
