I'm no electrical engineer (could be doing the math wrong), but I think there is a pretty glaring error in this page:

The author mentions a 400 MW wind farm, and then says that correlates to 400,000 homes. Unless homes in Denmark use only 3% of what homes in the US use on average[1], that number should be somewhere closer to 15,000 homes.

You have not accounted for the difference between power and energy. 909 kilowatt hours (energy) divided by a month (720 hours) is an average of about 1250 watts (power).

So 400 megawatts might only power 300,000 US homes, but the scale is about right.

No, this is a correct figure. I think you are confusing power with energy. Also, the consumption of the average US home is a lot higher than in Europe.
400 MW not 400 MWh. The power generated by the wind farm is enough to power 400,000 homes at peak. The link you provided talks about energy generated.
This would equate to a constant 1kW load per home which looks about right on the face of it. In fact that's probably a bit high.
Ah, thanks for all the replies.
