With the need for renewable energy growing, America needs to begin researching nuclear energy again, at the very least. Support for nuclear energy in America has waned every time there's a nuclear accident anywhere in the world but the rest of the world has advanced in both research & implementation. Ideally, we need to replace our current, aging nuclear reactors (most of which are passed ideal operating periods) with Generation 4 reactors which can use the nuclear waste from earlier reactors as fuel; has built-in protections against enriching material (for bombs); have been hardened against (terrorist) attack and, most importantly, has passive (automatic) systems to shutdown the reactor in case of emergencies. America need a host of advancements in nuclear energy, solar energy & wind-powered energy; they all need to be more effective, cheaper & more widespread. Until then, let's take that first, bold step into the future where energy independence is an actual possibility.
