Must-read piece up at Technology Review on how expanded U.S. natural gas reserves change energy calculus. Some of that is direct, with there being far more natural gas potentially available than imagined even five years ago; some of it is indirect, with a possible natural gas supply expansion representing a sort of circuit breaker in the face of oscillating and/or climbing oil prices.
There are many challenges of course, not least of which is the absence of natural gas-powered cars on U.S. highways. A wholesale auto fleet transition to natural gas is not in our future, at least not a rapid one. Then again, even the threat of a partial transition is an important development in the tight world of oil supplies.
