http://www.businessweek.com/news/2012-02-07/wind-power-market-rose-to-41-gigawatts-in-2011-led-by-china.htmlThe global wind power market rose 6 percent to 41 gigawatts last year, led by China, which captured more than two-fifths of the total, the Global Wind Energy Council said today in a report.
China installed 18 gigawatts of turbines in 2011, followed by the U.S. with 6.8 gigawatts and Indias 3 gigawatts. Germany, the U.K., Canada and Spain followed, according to the Brussels- based industry lobby group.

Despite the state of the global economy, wind power continues to be the renewable generation technology of choice, GWEC Secretary-General Steve Sawyer said in an e-mailed statement. 2011 was a tough year, as will be 2012, but the long-term fundamentals of the industry remain very sound.
Wind power capacity now totals 238 gigawatts worldwide. The 6.8 gigawatts installed in the U.S. last year could power almost 2 million American homes, and the industry is on its way to providing 20 percent of the nations electricity by 2030, according to the statement.

yup
FBaggins
(26,744 posts)How does the 6% growth rate compare to prior years' growth rate?
IOW, is the rate of increase accelerating or decelerating... and by how much?
jpak
(41,758 posts)If there are now 238 GW of installed wind power capacity.
and we added 41 GW last year to get to 238 GW.
What was the annual growth rate in 2011?
(clue: typos do happen - this is where critical thinking comes in handy)
yup
FBaggins
(26,744 posts)You're still not reading that right. Sorry.
6% is not the rate of increase in total capacity from last year (you would have gotten this had you actually done that division). It's the second derivative. The rate of change in the annual change.
What was that second derivative in 2010? 2009? etc? Is the acceleration in the rate of growth positive or negative... and to what extent?
kristopher
(29,798 posts)Now, about the rate of growth in the nuclear industry last year...
FBaggins
(26,744 posts)...but we're talking highschool math here.
It isn't a complicated question.
jpak
(41,758 posts)yup
FBaggins
(26,744 posts)Now the reading comprehension weakness is in your ability to understand your own article?
First of all. Global wind production isn't anywhere close to 6% of total generation.
But that doesn't matter. Because they're clearly talking about the growth in the size of the wind power market. That is... the amount of new generating capacity added in 2011 compared to the amount added in 2010. As I said... the second derivative. The amount they sold (in label capacity, not dollars) is 6% higher than it was in the previous year.
kristopher
(29,798 posts)Where did jpak write that wind was 6% of total generation? You misread the article and you are intent on trying to cover it up.
FBaggins
(26,744 posts)His post title was "The 6% refers to the contribution of wind to global generating capacity" You can twist that if you choose to, but nothing changes that simple fact that this is not what the 6% in the article refers to... as your correction to him makes clear.
kristopher
(29,798 posts)FBaggins
(26,744 posts)Everything else has been avoidance on your part and calling you on it on mine.
kristopher
(29,798 posts)You clearly construed the 6% as referring to rate of growth in installed capacity.
FBaggins
(26,744 posts)Where? I never did anything of the sort. That's how jpak MISconstrued the question... but I clearly asked for the prior year figure that's comparable to the reported 6%.
I have yet to get one.
On edit - How you can read "6% is not the rate of increase in total capacity from last year" and get "clearly construed the 6% as referring to rate of growth in installed capacity" is hilarious.
kristopher
(29,798 posts)1. How does that 6% compare to the last few years?
When's the last time it was this low?
FBaggins
(26,744 posts)Let me know if you need help with the math.
jpak
(41,758 posts)There are now 238 GW of installed wind capacity - after 41 GW was added in 2011.
238-41 = 197 GW that is the installed capacity at the end of 2010.
(41/197) * 100 = 21%
duh
yup
FBaggins
(26,744 posts)What you just provided is the first derivative. The 6% figure is the second derivative.
"Duh" indeed.
kristopher

You've become a self perpetuating joke, Baggins
FBaggins
(26,744 posts)If you simply answered it there wouldn't be anything to "perpetuate".
But you embarass yourself with this continual spamming of the thread while ignoring the question.

The global wind industry installed over 41 GW of wind energy in 2011, bringing the total global installed capacity to more than 238 GW at the end of last year, the Global Wind Energy Council (GWEC) announced in its latest report. This represents an increase of 21%, with growth in the size of the annual global market of just over 6%.
About 75 countries worldwide now have commercial wind power installations, and 22 of them have already passed the 1 GW mark.
Despite having faced a challenging year, China has consolidated its position as the global market leader, installing 18 GW in 2011 for a cumulative capacity of more than 62 GW. India was also a leader, installing over 3 GW of wind power in 2011 to push the nations total capacity to just over 16 GW - a number that is likely to go up to 5 GW per year by 2015, according to D.V. Giri, chairman of the Indian Wind Turbine Manufacturers Association...

FBaggins
(26,744 posts)The relevant quote from what Kris is showing you is "growth in the size of the annual global market of just over 6%."
I'm asking you for the comparable figure for the last three years. Is 6% a good number or a bad number?
If you can provide a resource for global wind capacity over the last decade or so, I'll be happy to do the math for you.
kristopher
(29,798 posts)FBaggins
(26,744 posts)And this thread proves it.
Once again... it was a VERY simple question and you guys are dancing around the subject. At first I thought it was that you knew the answer and didn't like what it says... but know it looks more like the problem is ignorance of simple mathematics.
Why you keep whining about it is beyond me.
kristopher
(29,798 posts)You are now trying to cover that mistake by a strategy of disruption.
Please stop.
FBaggins
(26,744 posts)Where in the thread is there an aswer to the simple question asked?
See your post #8. The 6% is the "growth in the size of the annual global market" - That is... the amount of new wind added during the year compared to the amount added the prior year.
What's the comparable figure for 2010, 2009, etc?
The disruption is all yours. It's a VERY simple question. Tell me the total capacity by year for the last decade and I'll tell you the answer.
FBaggins
(26,744 posts)The question is clear and simple. Your inability to answer it indicts your basic math skills.
Your continual spamming of the thread indicts your credibility and maturity.
1. How does that 6% compare to the last few years?
When's the last time it was this low?
That is what you wrote and it is obvious you were referring to the rate of growth in installed capacity. You screwed the pooch, just admit it and move on.
FBaggins
(26,744 posts)So what is it?
If you can't do the math... I'm happy to help.
kristopher
(29,798 posts)Using the economic crisis as an excuse Conservatives around the world have been attacking the transition to renewables, yet even so wind and solar grew. How did it turn out for nuclear?
FBaggins
(26,744 posts)I must have missed that. I could have sworn it was earlier.
I take it your attempt to dodge the question is because you know the answer and don't like it.

I'll leave you to count the beads.
FBaggins
(26,744 posts)So not too bad all things considered.
I wonder what their projection is for 2012.
Dead_Parrot
(14,478 posts)My money's on around 20%, FWIW.
kristopher
(29,798 posts)FBaggins
(26,744 posts)At what price? And with how much generation 2-3 decades later?
Is there a dollar figure for the size of the wind market in 2011?
