Nuclear power is becoming a more attractive alternative energy source to Americans, according to a new survey.

The survey results also indicated that the U.S. public is increasingly unhappy with oil and more willing to develop alternative energy sources such as wind and solar power. Also, while American concern over global warming is on the rise, people are apparently reluctant to pay to fight it.

"We're trying to understand what public policy in the U.S. should do to encourage new kinds of energy development or different patterns of energy consumption," said Stephen Ansolabehere, an MIT professor who conducted the study of 1,200 Americans.

The percentage of people who supported an increase in nuclear power grew from 28 percent in a survey conducted by MIT five years ago to 35 percent in the current survey. Ansolabehere said the increase was likely due to increased concern over carbon dioxide emissions from the burning of fossil fuels that is causing the current global warming.

Though support for nuclear power has increased, Americans still remain wary of the problem of storing nuclear waste. Nearly 40 percent of those surveyed opposed storing waste at Yucca Mountain, Nev., and only 28 percent agreed that "nuclear waste could be stored safely for long periods of time."

While doubts over nuclear power persist, oil has plummeted in popularity, ranking below nuclear power as the least popular fuel source. In the new survey, 74 percent of respondents wanted to decrease oil use, compared to 56 percent in the 2002 survey.

"People have really turned on oil in a big way," said Ansolabehere, who attributes the trend to rising prices and concern over the United States' foreign oil dependency.

Cost remains a major factor in energy choices, the survey results indicate. People favor using more wind and solar energy until they are told that such alternative energy sources cost more than traditional sources like oil, gas and coal.
