My dad is an energy lawyer who has recently been doing a lot of work with natural gas storage projects and he emailed me this Post article. It's an interesting read for those who care, and shows shale gas as a viable alternative (not solution, mind you) to petroleum dependence.

Sparknotes:
we have shit tons of natural gas, which is cleaner than petroleum. It is readily available and can help cut dependence on foreign oil by a decent amount. Also, it has massive positive geopolitical implications, particularly in Europe and Asia
