(CNN) - In response to a question about whether nuclear power plants are something the U.S. should consider for the future, Sen. Hillary Clinton, D-New York, said, "this issue of energy and global warming has the promise of creating millions of new jobs in America."
Clinton continued by saying that "it can be a win-win, if we do it right."
But she agreed with former Sen. John Edwards, D-North Carolina, who, in his response, said there is currently no solution to the waste and cost associated with nuclear power. Clinton said this was an area that can be explored and solved through new technology.
Edwards, however, disagreed, saying these problems were too hard to overcome and that he would not support creating nuclear energy plants.
"Wind, solar, cellulose-based biofuels are the way we need to go," Edwards said. "I do not favor nuclear power. We haven't built a nuclear power plant in decades in this country. There is a reason for that."
Sen. Barack Obama, D-Illinois, said he'd be open to nuclear solutions.
"I actually think that we should explore nuclear power as part of the energy mix," Obama said. Shortly after that, he criticized what he said was Vice President Dick Cheney's way of creating an energy plan.
"He met with environmental groups once," Obama said. "He met with renewable energy folks once. And then he met with oil and gas companies 40 times. And that's how they put together our energy policy. We've got to put the national interests ahead of special interests."
