Good summary. There is a big question about exports of gas, as that could raise costs significantly as gas would no longer be priced based on domestic requirements but would be a global commodity with higher prices. But then again gas should probably go to the market that can pay more for it, gas has much more value as a chemical / plastic raw material than it does as a fuel.
The changing cost of energy has many other implications. People have shifted to smaller more efficient cars and are driving fewer miles as costs go up, this means the total gallons of fuel consumed has and will continue to drop. The money that pays for highways is based on a fixed number of cents per gallon tax on motor fuel. As consumption drops the fund has dropped and will be exhausted next year. This will become a big fight in congress over how to pay for future road maintenance and road building.
But bottom line is that it is time for government to get out of the way and let the free market determine which future energy sources we will use.
