White is More Aerodynamic

While driving through Bretagne, I loved looking out over the hills and seeing the marching rows of wind turbines, so linear and powerful against the green hills. I love the presence of them, strong and seemingly indestructible and so forceful. So modern and futuristic.

Guess what people, the future is here.

Indifferent Cows; Dirk Ingo Franke

I am enamored with wind turbines. I think they are the cats meow. Perhaps I would feel differently if the turbine were in my backyard?! But the truth is that I don't have a personal backyard at this point in my life; the world is my backyard. And I am thrilled to see wind turbines scattered throughout so many parts of our globe.  It's incredible to see such a massive object, with such little environmental impact. Wait, let me correct that statement. Such little negative impact. Such a small (I'm guessing somewhere around a 10 foot diameter) footprint on the earth, with such dramatic positive impacts. They are graceful and serene and mesmerizing. They do not use fuel and do not create air pollution. They generate energy using a renewable resource (wind) and while cows may not share my strong enthusiasm, they are nothing less than indifferent.

I found myself filled with questions about wind turbines. If you are curious, read on!

What is the cost for purchase and installation of a personal wind turbine?
They are expensive: $6,000 to $22,000. Information I found states that the wind turbine could make back the investment in six to ten years.

Okay, well, that's expensive, but maybe there are tax credits or other forms of financial assistance?
Some fantastic incentives exist, but they are different from state to state. For example, Louisiana will
cover 50% (maximum $12,500) of the cost of each system. Awesome! As a larger state with greater expanses of land and larger wind farm opportunities, Oregon has very different and much more extensive policies that include residential, commercial, industrial, and agricultural tax incentives. Visit the DSIRE website for incentives for your state!

Can you get a little turbine? How about one for a suburban backyard?
Although mini-turbines exist, they don't appear to be very effective. An area of land no less than an acre is more appropriate. I expect that this will change over the years. Whoa....I just got a mental picture of IKEA having a store section of minimalist and classy wind turbines. A continuation on that small segway: the oyster transportation card of London is sponsored by IKEA and the small envelope that holds it has directions to all London  store locations. Nice marketing IKEA, you are awesome.

Will this really save me money? 
Apparently, the turbines can lower electricity bills by 50-90%. Sweet. But there is more to keep in mind...

"...the most cost-effective way to power your home is not to buy a larger, and therefore, more expensive wind turbine, but to examine how your electric bill got to be so high in the first place. It is always cheaper to use electricity efficiently, conserving where appropriate, than it is to generate large amounts of electricity that are squandered by energy-wasting appliances. Replacing your existing appliances with their most energy-efficient counterparts is always more cost-effective than installing a larger wind turbine."

- Mick Sagrillo, American Wind Energy Association

What is the life span of a wind turbine?
Wind turbines don't require any maintenance, operate automatically, and are designed to last up to 20 years. Apparently they can be refurbished to add on an additional 15 years of life. This seems like a pretty short life to me. I couldn't find information on how much "refurbishment" would cost, but I expect that it has a substantial price tag.

Wait a second, but we just learned that the turbine might not re-coop the investment for fifteen years. So electricity is only free for five years and then I have to buy a new one?
No answer here, but it sounds like yes. However, wind turbine technology has grown tremendously in the last fifteen years, so presumably, it will in the next fifteen as well. Still lingering on that IKEA image...

Is there any motor involved, at all?
Wind turbines don't have motors. They are constructed with very few moving parts and are powered solely by wind. 

How do wind turbines hold up in the event of an earthquake, hurricane, tornado, etc.?
It seems to depend on who installed it and what the quality of the unit is. And how strong the anchor is.

Do you have to get permission from your city or state to install the turbine?
Wind turbines require a Certificate of Approval (Noise) under section 9 of the Environmental Protection Act (EPA). But as usual, exceptions can always be made.

How do you hook it up to your own house and how does the electricity rebate work?
Apparently, wind turbines are pretty easy to hook up to your house. Now, I'm not saying that I or you could do it, but it's a pretty simple process for a professional. No wiring will need to be changed or modified to accommodate the turbine. After installation, you will have two utility meters: the standard one and your wind meter. Here is some more good news: federal regulations require utility companies to connect with and purchase power from small (less than 80MW) wind turbine systems.  When your wind turbine generates more electricity than needed for your personal use, the utility company is required to buy it back.


N says that wind turbines can be really noisy. How noisy is noisy?
Wind turbines make about as much noise as a washing machine. There is some controversy about whether the noise can negatively effect people over the long-term. 

Why are they always white? Why not fuchsia or pin-striped or covered with advertisements or patterns that create a trippy kaleidoscope effect?
N says that white is "more aerodynamic." I'm not buying into that one. But a little research found an article that suggested that black is the more aerodynamic of colors, at least for racing cars.  I couldn't find a suitable answer to this question, so perhaps there is a niche market for yours truly in the field of "wind turbine decorative arts?"

Some additional thoughts:
I want one for my very own.

Additional research yet to be completed:
Are there communities who have banded together to invest in wind turbines to be used by all members? I would love to read some stories on this...but no time to research.

What will replace the notion of a land of plenty? A fiction.

I.

This is a fiction.

Our destruction, my Gulf of Mexico, La Louisiane, Luisiana, Land of La Cadie, the lands I grew up in, it sickens me.

I know intimately and love dearly, how our destruction came. It came by truck, by an avoidable human waste called oil slick that imitates life... disaster hits the swamps. It makes me want to ask the world a question: What will we do to replace the notion of our planet as a land of plenty?

This land was named after the Micmac word for, “land of plenty.” Yet, we have took more than land could bear. It was new land. It was land for unkempt flood and excessive natural wealth. Our land - Louisiana.

News and continuing shock comes from another disaster in our homeland. Tears of mine reflect on me in the oil sheens of streetlights. The reels turn. Where will our lands rise hence?

II.

Life here mirrors the suffering of our city and countryside in small but no less absolute terms.

Children dive off rocks and swim in to a harbor that glistens with the coat of motor oil exhausted by the boats at anchor. Near the 400 year old Portugese fort there is a sheen that coats plastic bottles and washed up detris along with a thick grass in bright green algae and mosses.

On top of a brutal hard breakwater six small children are playing, they look up to me on a wall and smile… the sharp jetty will not cut their feet.

We never leave where we are from, where we are conscious, when we are from here.

III.

Valdez. Perhaps this one place where I gained my first memory expectation of the disaster. A human disaster in gold rush following a real disaster (black gold - slickening our natures)!!!

Louisiana and Alaska share much in common for being world’s apart. They are colonies in impossible to reach lands found critical for natural resource and natural human pathways.

....

I am walking the otherside. Beaches in Africa. Yet, their brutality and hard living make for only a small number of residents who can ‘make it’ where others try and give up. The salt air curls.

IV.

Martha Serpas, in her beautiful opinion article is summarizing the sweep of environmental, cultural, and economic destruction brought on us all with the most recent BP oil spill disaster. Her biases refer us to our state flag of Louisiana - where a pelican tears at its own flesh to feed its young. She writes - this 'message... stood too long.'

“Ecological self-sacrifice is not pious; cultural self-destruction is not our duty,” she says.

This is an analogy which I find applicable to the place where the world stands today.

Our citizens and civic leadership ready and willing to lend hands as stewards of our planetary health - but under what conditions? When will our efforts begin? Who will shepherd the costs?

V.

Pictures, images, stories from home are always so valued to us as we are off in these distant lands. When we read about what you are reading, when we hear the local anecdotes and your news, it reminds us of the similarities which all of us share with the world.

This week in Morocco, we were invited to attend a wedding, we visited festivals, passed funerals, saw school groups taking field trips to the sea. If you are involved with something special, please share it. We love to hear about you. Many other people do to. You are the shepherds of our trail.

This was my excerpt, a personal fiction, devised for response to a very nice piece of Louisiana literature. ‘Well done, Well said,’ I say. Beautiful Op-Ed by Martha Serpas.

....

It is also a beautiful and morbid reminder of how environmental degradation, human oppression, sordid incongruous power histories - through them all - that it is human resiliency which has overwhelmed the events of disaster. We are the caretakers because we contain a memory of soul on planet Earth. I can remember. I was in VALDEZ, AK, just after the oil spill. It was external and internal. There was a convergence of the sacred, the profane, and our time.

The Great Oil Spill

written by Nathan, May 2, 2010

The great oil spill of 2010 that now slickens the coastal fisheries of our home Louisiana looks particularly offensive from the coast of the Atlantic in West Africa. It is, however, easier to make out through the horizon of thickening plots and dying seas just how wealth generated from our seashores of home mimics colonial trespass, management of land purchases, and the like. A long history of exploitation does not even find financial benefits or economic justice in the riches still pouring from the Louisiana purchase 200 years on.

Louisiana, an economic boon for the United States, is still only an afterthought in discussions of economic justice, resource degradation, and oppressed peoples. While all classes of people are affected by the dangerous physical and environmental degradations at place on the Louisiana Gulf Coast wetlands, our political class will make no collective efforts at restitutions and environmental clean-up and reconstruction so long as they are in the pockets of status quo decision making. Other classes have no power. While we laugh at our tongue-in-cheek state motto, “Louisiana - Third World and Proud of it,” we do not seek meaningful change or equity improvement either as a nation or locally.
