But the speculation about what this means for a much-touted nuclear "renaissance" in the U.S. has begun. As the New York Times reported Monday, "U.S. Nuclear Industry Faces New Uncertainty." Some quick background: For years, no new nuclear plants were built in the U.S. But nuclear power is now being taken seriously again. Roughly 30 to 40 applications for new plants or expansions to existing facilities are moving through the process with the Nuclear Regulatory Commission (NRC). One of the main reasons nuclear is "back" is that it satisfies two very distinct interest groups: (1) pro-energy lobbyists and companies that usually sit on the right (although President Obama has adopted the rallying cry of "all-of-the-above" as an energy independence strategy as well), and (2) those who want to aggressively fight climate change, who usually camp out on the left.
