Chernobyl proved American and Canadian nuclear power systems were a lot better than Russian nuclear power.
Three Mile Island was nowhere near as bad as people make it out to be.
There were no detectable health impacts from TMI, with an average dose of an x-ray for people affected But environmentalists made nuclear out to be the worst thing since the opposite of sliced bread. And that is why the US won't build any more nuclear plants, even though coal plants give off more radiation than nuclear plants. Guess where all that radiation goes? The air. Wouldn't you rather have the radiation on the ground where we can dispose it instead of in the air where we have no control over it?
Chernobyl caused 50,000 people to evacuate, and it shows the lack of safety in the plant. There are two reasons - the operators had conducted an experiment at Chernobyl just before the meltdown, and the plant did not comply with accepted nuclear power standards. So it was a substandard nuclear power plant - it means nuclear remains a viable alternative to fossil fuels if built to safety standards. Cost cutting would lead to disaster. So yes, safety comes first. Now if we could get politicians to see that - I'm looking at you Obama.
Renewable energy needs subsidies to even be worthwhile. I'll throw out another link and summarize it for you.

Technology Cost (USD/MWh)
Advanced Nuclear 67
Coal 74-88
Gas 313-346
Geothermal 67
Hydro power 48-86
Wind power 60
Solar 116-312
Biomass 47-117
Fuel Cell 86-111
Wave Power 611
However, this incorporates subsidies - 0% for coal, 14% for nuclear, to over 100% for solar power. Yet, even with a subsidy for solar power, coal power is cheaper than solar power! So the viability of solar power in a large scale isn't there for me. Compared with CA's subsidy, the USA only offers a 30% tax credit. I'd look for cheaper solutions.
Wind power - 30% tax credit in the USA. That puts nuclear power cheaper than wind power. This looks to be the best solution, however, for the Great Plains, and especially the Pacific Coast, the Atlantic Coast, and the Great Lakes.
Hydroelectric power - the problem with it is that there are very few locations to put dams on compared to solar panels, or wind turbines. However, we've got a lot of rivers dammed already, so I'd say look somewhere else.
Geothermal power - Doesn't need oil or coal, but the initial start-up cost is high. Best locations in the USA would be near the Juan de Fuca/Pacific - North American plate boundary - this means the Pacific coast.
And yes, oil spills are no big deal in the long term. Maybe I should have clarified earlier. The Exxon Valdez oil spill - the area is aesthetically back to normal, mostly. And since there is a natural process in which oil can be decomposed, the environment will return to normal - it's just that cleaning the environment makes the process go a lot faster.
Besides, this seems to be a repeat of Ixtoc I. Both suffered from wellhead blowouts. It took 10 months to cap the well from Ixtoc I, and that leaked 3,000,000 barrels of oil. However, the leak was slowly brought under control due to the pumping of mud, and later, 100,000 steel, iron, and lead balls. BP's control mechanisms, however, aren't bringing the leak under control. So it looks like Deepwater Horizon will be worse than Ixtoc I. It shows two things. History repeats itself, we didn't learn from Ixtoc I. And the second thing, if safety doesn't come first, then disaster occurs. Just like the Challenger disaster - engineers got overruled by their managers. End result? Deepwater Horizon blows up and oil spill occurs.
