The nuclear disaster in Japan is likely to have major effects on US energy policy, according to billionaire investor Warren Buffett.
Buffett, the chairman and CEO of Berkshire Hathaway, said the events in recent weeks have altered public opinion in America.
"Radiation terrifies people," Buffett told CNBC. "It's unseen, there's no way to quantify sort of the limits of what might happen from it so I would say that I would be very surprised if there's any nuclear facilities built in the United States for a long time."
Berkshire Hathaway owns 90 percent of MidAmerican Energy, a utility company. Most of MidAmerican's electricity generation is powered by coal-fired plants.
The United States was poised to move ahead with nuclear plans here, but the events in Japan derailed that, according to Buffett.
"The public opinion was starting to shift in the in favor of nuclear, the administration favors it, I favor it," he said. "But it isn't going to happen because the psychology has changed."
