Rising Energy Costs and the Possible Economic Crunch

Now that gas has hit $3 a gallon again, I have started to wonder how society would change if gas stayed at $4 or more gallon for a year or two.  The obvious answer is that electric, natural gas and other alternative fuels vehicles would suddenly become practical.  But a deeper answer is we might develop the energy infrastructure to take advantage of the efficiencies in using freight trains.  We would possibly develop more local oil fields to increase our local supply.  It is reasonable to expect significant changes in our way of life in the the next 10 years. So keep in mind that being conservative financially will keep your options open. Having a years worth of food storage will keep you fed.
