You need a combination of solar, wind, geothermal, hydroelectric, and yes nuclear. What some forget is base load power. One of the main reasons natural gas is used as an alternative for coal despite still producing carbon emissions is because it also can be used as a base load electric grid fuel. Nuclear can provide clean base load power.
I understand many are concerned, especially after the terrible tragedy at Fukushima; however there are ways we can prevent that tragedy from ever reoccurring. By transitioning to nuclear technologies utilizing fuel cycles that consume nuclear waste or use fuels capable of reducing risk of meltdown accidents, we can get closer to both clean energy and safety. We don't primarily need nuclear but it should be considered in the mix at least for baseload considerations.
