WASHINGTON (CNN) - When asked by CNN's John Roberts about his opposition to Nevada's Yucca Mountain Nuclear Repository, Sen. Barack Obama, whose home state of Illinois gets 40 percent of its power from nuclear energy, said "I don't think nuclear power is necessarily our best option. It has to be part of our energy mix."
Obama said he supported the development of new ways to safely store nuclear energy, eliminating the need to transport nuclear waste across the country. Obama also said he supported charging polluting companies for their pollution output, with the money raised being reinvested in clean forms of energy.
