Nuclear Power Vs. Windmills, Which is Better? Nuclear power%26#039;s biggest problems are economic: it is simply no longer competitive with other, newer forms of power generation. The final 20 U.S. reactors cost $3 to $4 billion to build, or some $3,000 to $4,000 per kilowatt of capacity. By contrast, new gas-fired combined cycle plants using the latest jet engine technology cost $400-$600 per kilowatt, and wind turbines are being installed at less than $1,000 per kilowatt.

Windmill power contracts were signed with power sold at three (3) CENTS per Kw-hr. Less than half the price of the most efficient solar cell panels. 56% 5 Votes 11% 1 Vote
