"It would take 10 to 15 years to bring any significant oil online..." That depends on who you talk to, a Democrat would agree with you. Republicans say 5 to 6 years.
"these prices have nothing to do with supply and demand..."??
Have you watched the day to day fluctuation in oil prices?
When the rebels in Nigeria act up and cut supply...the price of oil rises, when Iran fires off a couple of rockets, just the threat of an oil shortage...the price of oil rises, when there is a strike of oil workers in Brazil...the price of oil rises. The balance of the supply of oil and the demand for oil is directly responsible for the price we pay for gas, heating oil, and any oil based procucts.
