According to Benjamin Sovacool , nuclear power plants rank first in terms of their economic cost , accounting for 41 percent of all property damage . Oil and hydroelectric follow at around 25 percent each , followed by natural gas at 9 percent and coal at 2 percent . Excluding Chernobyl and the Shimantan Dam , the three other most expensive accidents involved the Exxon Valdez oil spill ( Alaska ) , The Prestige oil spill ( Spain ) , and the Three Mile Island nuclear accident ( Pennsylvania ) .
