This is one of my favorite interviews from our cross-country eco-video
project, when we met Cliff Etheridge in Roscoe, Texas, home of the
world’s largest wind farm.
The way Cliff explained, the rural town of Roscoe was dying out, and
once the Dairy Queen left town they knew they were in trouble. Cliff
had just retired as a cotton farmer and knew about the wind farms in
nearby Abilene and Sweetwater, and was interested to find out if
Roscoe could have a wind farm too. There is both plenty of wind and
plenty of open space in Roscoe. He brought in wind experts to assess
whether or not a wind farm would work there, and then got the support
of the townspeople for the idea.
A few years later, the world’s largest wind farm now stands in Roscoe,
Texas with 631 wind turbines producing enough electricity for 250,000
homes. Farmers and landowners are paid by the company who owns the
wind turbines for leasing their land, and they continue to farm around
the turbines. In a rural farming community, that extra money really
helps keep the local economy going. As we saw in so many places,
there are a variety of reasons to support renewable energy: the
environment, the economy, national security, etc. In fact, the week
before we arrived in Roscoe, Cliff won ‘Environmentalist of the Year’
from the state of Texas!
Standing in a field of 631 massive wind turbines was an amazing
experience. It was actually very quiet - just the noise of the wind
blowing. It made me wish that everyone who opposes wind farms could
stand where I was to experience it for themselves. They are quite
majestic, in my opinion. Our local newspaper just featured an article
on building wind turbines here in central Massachusetts, speaking of
the several that have been built in the last two years, and others
that are on the way. I read the online version of the article and it
was of course followed by comments on the website about how wind
turbines are noisy, kill birds, are a bad investment, etc. People may
not like how they look, and that's their opinion of course. I've
heard some complaints about wind turbines being noisy but I've never
experienced that myself with the turbines I've been close to. I know
the smaller residential wind turbines are are noisier. Many studies
have been done about bird mortality with wind turbines and it's
generally found that wind turbines kill about 2 birds per year. Cats,
windshields, and plate glass windows are a far greater menace to bird
populations than wind turbines. As far as wind turbines being a bad
investment, our first video in the ORN series features the wind
turbine at Holy Name High School which has a 7-year payback and then
free heat/electricity for years afterward. The Roscoe wind farm was a
business decision, to boost the economy of a rural town that was
dying. People can argue the numbers all day but in the meantime that
doesn't stop people from investing in renewable energy and
experiencing the very real benefits. If you hear or see these
arguments I encourage you to help counter them and try to correct some
of the misinformation out there.
Enjoy!

ORN#5 Cellulosic Ethanol
Hi friends,
Before I get to the newest video, I want to say thanks for the ratings and reviews on ITunes! If you haven’t yet, please check us out on ITunes and leave a rating and/or review, which helps us get notice in a very large ITunes world. Just do a search for Our Renewable Nation in the ITunes store.

Our latest video, ORN# 5 Cellulsoic Ethanol, is Carrick’s tour of Verenium’s demonstration plant in Jennings, Louisiana. Verenium has been developing a process of using high-energy crops and native plants to make cellulosic ethanol to fuel cars and trucks.
Ethanol has been a controversial alternative fuel to gasoline, with a lot of headlines and politics involved for the last several years. Much of the gasoline now sold in the U.S. has a blend of 10% ethanol, which is being made from corn. Making ethanol from corn really gets into a whole host of issues, like growing food crops for fuel. Corn is an energy-intensive crop to grow and farmers end up using a lot more energy to grow and harvest the corn than we get from using the ethanol in our cars. Then there’s the problem of rising food prices because the corn is being used for fuel instead of food, and corn is in A LOT of food we buy (watch the movie King Corn or read the book ‘The Omnivore’s Dilemma’ by Michael Pollan for more on that). Plus, even planting every acre of land available in the U.S. with corn to make ethanol wouldn’t get us anywhere near what we use for transportation fuel in this country.
Cellulosic ethanol can be made from native plants and grasses that need very little help to grow abundantly, and from crops that are able to produce many times more ethanol per acre than corn. One of the big challenges with producing cellulosic ethanol is breaking down the cell walls to get at the sugars trapped in these plants materials. Verenium has developed a process of conditioning and pressurizing the plant materials then adding enzymes to break down the cell walls, making it possible to yield a much greater amount of ethanol from plants than the process of producing corn ethanol.
On our cross-country journey we were given a rare opportunity to visit and tour Verenium’s cellulosic ethanol demonstration plant in Louisiana. This is not a place that is open to the public. In fact, no kid has ever walked through the facility before Carrick. There is a lot of money invested in developing this process and a handful of other companies are in the race to perfect the secrets to making cellulosic ethanol. Naturally, they are selective about how many people they bring through, so we were very lucky!
You may notice this is a short video, shorter than normal. During our tour of Verenium I couldn’t imagine how we were going to take a subject as complex as cellulosic ethanol and make a 5-minute video for a broad audience including kids. There was so much to show and tell, and so many issues involved that in the end I decided to keep it short and not overload it with information. There is a lot of discussion and debate about ethanol on the internet, so our video serves as a “taste of” and anyone interested can do more poking around on their own.
We use SO MUCH gasoline in this country for transportation that it’s hard to imagine any one source of fuel that we can produce to take its place. That’s not to say it can’t be done, it’s just to highlight the tremendous challenge any alternative fuel faces. Making vehicles more fuel-efficient is one way to help meet that challenge. Also, the idea of a Chevy Volt-style hybrid with a fuel-driven range extender would dramatically lower our use of fuel by letting us drive on electricity most of the time and only use fuel when driving farther than 50 miles.
Before I close this out I want to mention the upcoming sustainability fair in Hull, Massachusetts by our friends at Sustainable South Shore, who helped sponsor our project. We went last year and it was great – here’s more info:
