The addition of wind, solar, and nuclear power will have no impact on our dependence on oil. All of those sources of energy would be used to generate electricity. However, when it comes to the generation of electricity we already are oil independent. That is, virtually no electricity is generated from the use of oil. Instead our electricity is generated primarily from coal, hydroelectic, and nuclear power. Only 2% of our electircity is generated from oil based power plants.
It is in the area of trasportation that the majority of oil is consumed in this country. Approximately 75% of the oil imported into this country is converted to gasoline and deisel to fuel our cars, trucks, and buses. Hence, it is in the transportation area that we must find alternatives to oil. The good news is that there currently are substitute fuels available -- ethanol, methanol, battery power, and natural gas -- and the technology available to immediately begin production of vehicles using these alternative fuels.
The most promising of these vehicles for immediate mass production are the hybrid cars, which use a combination of battery power and gasoline, and flex vehicles, which are capable of using ethanol, methanol or gasoline, or any mixture of these products. Right now Brazil has become foreign oil independent having undertaken a program beginning in the 1970s to require that vehicles in Brazil be flex vehicles. This has been possible because the automakers are capable of converting conventional vehicles into flex vehicles at a cost of only an additional $100 per car. The flex cars in Brazil run primarily on ethanol that is produced from sugar cane grown in Brazil. Currently more than half of the energy used by cars in Brazil is in the form of ethanol.
Right now there is a bill to promote flex vehicles in the United States, but unfortunately it is hung up in Congress. Lets put the pressure on our congress by writing to our senators and congressmen to allow the bill to go forward.
However, the conversion of the American car fleet to flex or hybrid vehicles is not an immediate solution to our oil dependence.
Vehicles have approximately a 16 year life span within the United States so existing gasoline cars will be with us for some time to come even if we were to begin selling only flex and hybrid vehicles immediately. That is why it is equally important that we expand drilling in this country to take advantage of as many of our oil deposits as possible, including off-shore drilling. This will not only have the longer range effect of reducing our dependence on foreign oil, but will also have the added benefit of having an immediate impact on lowering the cost of gasoline. (see my post Drill, Drill, Drill).
