Compare this to the financial costs of nuclear energy. To achieve a situation where 20% of current national electricity production was nuclear power would require the construction of at least five typical nuclear power plants, each with a capacity of around 1000-1500 MW (a typical reactor size).
Based on several recently commissioned third-generation reactors in Japan and South Korea, these reactors would cost between $1500 and $2000 per kilowatt to commission, and therefore between $11.25-$15 billion in total.
Clearly, nuclear power is more expensive. Once built, the plants require fuel rods, an additional cost, and these must be enriched at a separate facility, which would cost upwards of $500 million.
Nuclear power has higher operational and maintenance costs compared to wind power, and nuclear power stations take longer to commission (seven to 10 years) than wind turbines (three to six months once delivered). More carbon dioxide is emitted in the construction of a nuclear power plant, and in the enrichment of fuel rods, than in the construction of wind towers.
