While the idea of increasing nuclear power is one of the leading solutions, it still has to get past some negative fall-out from previous events (i.e. Chernobyl and Three Mile Island). These incidents are the reason why the law (in the U.S. anyway) makes it hard to build one and why there hasn't been one built in the last thirty years. The other critical point nuclear power plant supporters have to break is the popular idea of NIMBY (Not In My Back Yard). The fear of nuclear meltdowns is so great that coal-plants can't build hyperbolic cooling towers (one of the most efficient type) because the public at large believe the towers are nuclear reactors.
To sum it all up, until the public at large welcomes the idea of nuclear power and gets past previous nuclear mishaps, you won't see many reactors built in America.
