While I agree there are risks, the chance of any accident is not huge, and even if there is an accident, the chances of it being a huge accident are almost nonexistent. The thing is that fossiil fuels also have their own risks, espeically oil spills. Besides, their emmissions contribute global climate change. Point being, personally I feel that the best way to deal with increasing energy needs is to increase our nuclear capacity instead of using more fossil fuels, until such a time that fully renewable energy is feasible. I do like the the idea of a decentralized grid of renewables, but again the problem is that not all places have access to the same renewables. In a place like Finland during the winter, there is really nothing except the wind, and how do you get electricity when the wind stops blowing?
