Not exactly encouraging:
We legislated against natural gas after the OPEC embargoes. Then we pinned all our hopes on natural gas and built capacity like crazy people. Then all the nukes were canceled based on one accident, during which, by all accounts, the safety systems actually behaved the way they were supposed to, avoiding a truly calamitous event. Now sequestration is the answer. We keep regulating, legislating, and reacting to one-time events or one type of pollutant with short-term measures.
