No it's not? The fact that the energy supply can adjust to demand is a good thing rather than a problem. At least in the US. Looked into it, and it seems that there's an estimated to be over 300 billion barrels of recoverable oil that is mostly economically viable. Compare that to a current annual consumption of 7 billion barrels a year. There's enough to maintain current consumption for another 40 years. That is most of my remaining lifetime from domestic production alone.
