Dependency on Foreign Oil

Here is my plan to cut our dependency on foreign oil by twenty percent in five years. Replace all of the government vehicles federal, state, and local with some sort of hybrid. I know this doesn't sound like much but if we could get just 5mph better per vehicle the savings would be surprising. Think about it. If the cars used today get 25mpg and they bought cars that get 30mpg just how much money that would be. 1 car driving 20,000 miles in 1 year at 25mpg would use 800 gallons of gas at $3.00 per gallon and that would cost $2,400.00 per year. If that same car got 30mpg it would use 667 gallons and cost $2,000.00 per year. That is a savings of $400.00 and 133 gallons of gas per car. Now think about how many cars the government has. I'm not sure what the exact numbers are but I will bet it is at least 100,000. If so that would be 13,300,000 gallons of gas and $40,000,000.00 per year. That is what 5mpg could do. If they would use hybrid cars that get 40mpg or more........well you do the math.
