The Vogtle nuclear power plant cost is projected to balloon to more than $12,000 per megawatt. In a study we did for the California Energy Commission in 2009, even at $4,000 per megawatt, nuclear power was uneconomic. This explains why nuclear power is not taken seriously as a solution to reducing greenhouse gas emissions.
