On Why Wind Farms Can Be Relied On For Almost Zero Power

As much as I would like to write about wind power in Denmark, you must keep in mind that the readers of this site are largely American. I like to have readers.

On The "Historic" US-China Climate Change Deal Confirms that We are Failing in the Fight Against Climate Change

Willem,

I really do not understand your attitude. I asked you not to copy and paste stuff into the comments. Copying and pasting stuff from your own articles is rude, and is little more than self promotion.

In response to this your have literally copied and pasted your first comment into your second comment. Your first comment already exists. Why do you need to fill up a second comment which is identical to the first?

So we have the following in comment one:

"Biologists estimate at least 50% of the world's land and sea area needs to be kept in a near-unspoiled state for the other fauna and flora.

There is such a thing as the 360 degree systems approach."

And in comment two:

"Biologists estimate at least 50% of the world's land and sea areas need to be kept in a near-unspoiled state for the other fauna and flora; it is their healthcare system!! There is such a thing as the 360-degree systems approach to solving problems."

Why you are writing the same thing twice? You have written this in a blog post, and then copied it into a comment below a piece of mine. I complain about you copying and pasting this stuff. How do you respond? By copying and pasting the stuff all over again. Please behave.

"I was in no way commenting on what you have written".

Then why were you commenting?

Once again, it is incredible rude of you to be copying and pasting stuff from your own articles into my columns. This is happening too often.

Hans,

I have no idea what you are implying with this "analyze it without prejudice" nonsense.

If you are suggesting my stated capacity factors are wrong then say so. Don't hide behind insinuations that I am prejudiced. I quoted the Boccard study and then I said recent production data confirms that the Boccard estimates are still reasonable. In addition, I linked to UK government estimates of wind farm capacity factors which explicitly account for new build.

But perhaps I will provide more data so that we can put aside your insinuation that I am prejudiced. Germany's total installed wind capacity went from 31.3 to 34.3 GW last year. Their total wind generation was 53.4 TWh. This would give an average capacity factor of at most 19.5%.

Perhaps you could have done this calculation yourself before implying that I am offering up prejudiced analysis.

Nathan,


For most markets fuel cost parity is what we should look at instead of grid parity. I considered mentioning that in the conclusion, but it's really another article.

This is particularly obvious for regions where peak load is 6 pm in winter, e.g. most of Europe. In these spots solar can do nothing other than save fuel. So, fuel saving makes perfect sense there. It is a bit different in markets where peak demand is in the middle of the day in summer. In those locations solar can provide capacity as well as generation. Whether wind farms can be viewed as providing capacity is debatable. From memory the Germany grid operator assumes that it cannot. The key problem is that historical output data shows wind farm at close to 1% of capacity at the same time as the annual load peak. So most grids will likely end up so that they would function if all of the wind farms were removed from them.

Ben,


This is a 1000 word piece dealing with the specific issue of how low wind power output can go.

As for capacity credits. You have got this the wrong way round. You claim that as wind penetration increases, the capacity credit also increases. Not true at all, as most studies that have looked into it show. The same goes for solar. Relevant studies referenced on Vaclav Smil's website.

You make a lot of assertions here, but don't provide any real numbers. Are things any different in the US? Does Texas not experience lulls that last many days? I do not see how EVS get you around this problem. And this talk of storing electricity in EVs is all rather fanciful. The US transport system is positively mediaeval. You can hardly even buy a diesel car. I don't take talk of storing excess wind energy in American EVs seriously. The US transport fleet is barely where it should have been in the 1980s, and the same goes for the electricity grid. Talk of smart grids based around EVs is misguided.

Who are you, "Engineer-Poet"? If you are interested in a pissing match, perhaps you could supply your real name. That would be the grown up thing to do.


"Utter lack of ongoing damage", Fukushima "trivial". Either you are paid to say such things or you are a truly heartless individual. Which is it?

A "hopeless waste of time"? You were the one who brought up the train of thought in the first place. So, when I ask you to provide evidence to back up your assertions, you turn around and demand that I find a way to quantify something. I guess this is what discussion forums are for. Evidence free assertions.

You are clearly elevating the quality of debate to a higher dimension by quoting me. You see, some of us use numbers to question our pre-existing beliefs; others use them to confirm them.

Yes, I'm sure that Feynman was a huge fan of obligatory renewables versus nuclear pissing matches.

Is a grown up discussion possible? Imagine, a bunch of grown ups (preferably not all men) actually discussing a specific issue without it turning into a "my favourite energy source is better than yours" argument in ten minutes. Are such things possible?
