I calculated for german capacity factor 19 % from 2011 data. There was on
average 28 GW wind power installed during the year and total output was 46

Your assumption is

It must be considered that windmills in Germany are quite old. And
efficiency has improved quite significantly in recent years.
The equipment wears out in 20 years and it is scrapped and replaced. Only
the towers remain. Fortunately, the tower is
In solving the baseload elex coal problem, I had to generate enough ammonia

One way I looked at was to carpet the Dakotas with wind energy generators

An interesting hybrid approach. Things that sound complicated like this

This is a little complicated. Honestly, too complicated for a spreadsheet
or for my limited mathematical abilities.
We have a moving target and two sets of numbers, one ending in December and
the other in November. There are reportedly ~60,000 MW of wind turbines in
the U.S. as of the end of
The bulk of the new 2012 installations happened on Q4. This amounted total of
8380 MW new wind power. This would imply that the capacity factor in 2012 was
near 0.3 what is usually rounded up into ⅓.

That would produce 155,789 GWH which is still considerably above the actual

I did more exact although still crude approximation using following
formula:
(47GW+(13.1GW-8.4GW)×.7)×.285×24h×366 = 125 900 GWh
This formula considers that 8.4 GW was installed on Q4 . . .
Thanks! It is actually a little better because the

Optimistic:
The Dutch national wind capacity factor is a dismal 0.186. The German
wind capacity factor “is even more dismal at 0.167,” the article

The Brits put it at 15%:

This is not optimistic or pessimistic. This is actual performance data
It is surprising that everyone hates German wind power expect germans
them-self. Windmills are very popular in Germany and local politician must do
unpopular decisions such as reducing the tariffs, because German grid
infrastructure has hard time to handle the peak loads caused by windmills.
