Since gonzomax continues to throw out assertions and refuses to back them up, I figured that I should do a little work to show what he’s babbling about. My doing this work by no means excuses his continued bad scientific behavior in this thread.

According to the American Wind Energy Association 4th-Quarter 2009 report, new wind capacity increased by 9,922MW last year: http://www.awea.org/publications/reports/4Q09.pdf
According to the DoE EIA, total wind capacity was 23,847MW in 2008 (http://www.eia.doe.gov/cneaf/alternate/page/renew_energy_consump/table4.html), and the total net generation in 2008 was 52,025,898 MWh (http://www.eia.doe.gov/cneaf/alternate/page/renew_energy_consump/table3.html). Doing the math, we get:
52,025,898 MW*hr / (8760 hr * 23,847MW) = 0.249, or 24.9%.
Comparing this to nuclear: according to the DoE the net 2008 nuclear summer capacity was 100,755MW, divided over 104 plants (http://www.eia.doe.gov/cneaf/electricity/epa/epat1p2.html). The actual generation in 2008 was 806,182,000 MWh (http://www.eia.doe.gov/cneaf/electricity/epm/table1_1.html). Doing the math, we get:
806,182,000 MW*hr / (8760 hr * 100,755<W) = 0.913, or 91.3%
So in effect, that 9,922MW of wind capacity added last year must be weighted by the ratio of the net capacity factors.
9,922MW *(0.249/0.913) = 2,706MW
So if we assume a modern design of 1300-1600MW for a nuclear unit, we see that approximately 2 modern nuclear units worth of generation were added last year.
Note that I am making no comment on the timing, frequency stabilization, pollution, or other factors, I am only showing how the claim might be justified at a high level.
- Note - used 2008 numbers for calculating the NCF since the 2009 numbers are not final. I would expect no more than a +/- 5% error.
