To follow up from Josh's post above, we shouldn't be dependent on just one source for energy. Let me give you all some numbers I looked up to think about here: 70% of electricity in the United States comes from fossil fuels alone (coal, natural gas, and petroleum). Meanwhile, about 90% of France's electricity comes from their own nuclear plants, hydro plants, and other renewable resources. They don't have to rely on foreign sources nearly as much. Why can't we be like that?
Anyway, regular unleaded gasoline is $3.26 per gallon in my area today.
