Untill we make improvements in the green energy nuclear power is a good short term solution. (Altough the waste certainly is a long term commitment.)
Consider; with almost no government subsidies, with major white-anting from the dirty energy industry backed, in many places, by the state, and with little private investment- solar energy has halved in price every year for the last ten. It is already cheaper, on aggregate, than coal fired-power (and probably nuclear as well).
The answer is a properly funded solar-energy development program, and victory over the dirty energy/conservative movement. Within a decade, everything will be powered by solar energy- the choice is whether the US and Australia produces that, or whether Germany and South Korea will. It's looking like, because the German/Korean political system is less corrupt and more responsive, the US will voluntarily surrender a major competitive advantage.
Nuclear energy is a joke. The massive handouts to the industry, including those in the form of R and D, are wasted, because the industry won't exist out of submarines in two decades. The US is paying to make better horses-and-carts in 1910, because the cart industry owns a bunch of congressmen.
