Although much of the world's attention is focused on variable renewable energies as a solution to the emissions problem, nuclear power can also play a role in reducing the total emissions created during electricity production. Nuclear energy provides a low-emission energy source that does not vary with the weather and is not subject to the volatility of the hydrocarbon markets. However, nuclear power must overcome its own set of constraints and obstacles if it hopes to compete with other energy sources. And although the world's capacity for nuclear power is likely to expand, the United States probably will not substantially increase its capacity; rather, it will serve as a technological developer that helps other countries ramp up their use of nuclear energy....
