I believe Nuclear power is a viable stop-gap in energy production between moving from fossil fuels to renewables. Right now, renewables do not create enough sustained energy to maintain the growing energy needs of many of the world's nations. Eventually, we will have to move towards figuring out how to capture more of the energy given off by our Sun and also the energy given off by the Earth's weather system. The radioactive component of Nuclear power makes it a poor choice to service energy needs in the long run.
