Wind power in Pennsylvania

Share

I traveled back to Pennsylvania last week for my high school reunion. As you may have noted from some of my recent posts, I’ve been investigating energy, particularly renewable forms of energy. It had been three years since we’d been back in the Wyoming Valley and so I was quite astonished to see 12 large wind turbines plainly visible on top of the eastern ridge of the valley up near Bear Creek. Each 2MW Gamesa turbine provides enough electricity for about 600 homes.

I’ve written about wind turbines before in my blog because they started springing up in Colorado a few years ago and whenever I travel across Nebraska and Iowa in the LongEZ, I seem to find more of them each year.

I had yet to get up close to a wind turbine so Terri and I decided to take a drive up to the site. As you may know if you’ve ever traveled around this area of the country , the closer you get to something, the harder it is to find. In other words, you can’t see the forest through the trees. We drove up Route 115 into Bear Creek and the wind turbines all but disappeared behind the mountains and trees. We continued to drive in the general direction of the turbines, and every once in a while, we’d catch a glimpse of a blade to help reorient us toward the wind farm. After driving in a circle, we eventually found the access road to the wind farm, just off Bald Mountain Road. We saw a lot of no trespassing signs, but felt it wouldn’t hurt to go up to the maintenance office to see if we could get permission to drive up to the first tower. I found a friendly engineer there and we began to chat and he said we could drive up to the first tower and take a look around. I was most interested to hear one of these wind turbines from up close.

We were able to get quite close to the turbines and found that the noise they made was hardly noticeable and certainly not objectionable. I asked the engineer why there is controversy when it comes to wind turbines and he felt that people have been conditioned by those who have a vested interest in non-renewable forms of energy attacking them for various reasons that border on being ridiculous. For example, a common objective I hear is that wind turbines kill birds. More than 100 million birds are killed each year flying into windows in the U.S. alone, yet you don’t see anyone trying to ban windows. A similar number are killed by house cats and cars. Wind turbines kill only 1 or 2 birds per turbine per year. Even with the thousands of wind turbines deployed and planned, this number will always be at least 3 orders of magnitude less than the other causes I listed, and so bringing up one’s concern for the well being of birds is a rather odd objection.

Opponents also say that wind turbines kill bats, which eat mosquitoes, that may carry West Nile virus. Again, I think this is really reaching by people who are unaware of the benefits of renewable energy and afraid of any unlikely downside potential, such as lowered property values. I’ve also heard of people fearful that wind turbines cause audible noise but I can attest from my own experience that the noise was not very noticeable. I’d gladly trade wind turbine noise for the noise that comes from the highway 1/4 mile from my house.

I can understand the people who live a few hundred feet from a wind farm being concerned about noise, but I grew up less than 300 yards from a working coal breaker that operated 24 x 7 and it made quite a racket, yet I never knew of anyone complaining about it. It also released plenty of coal dust into the local environment as well as the final product which has significant environmental hazards. So maybe I have a different perspective on environmental noise and pollution than someone who has built a house on a mountaintop.

On the way back down the access road, we came across a large flock of wild turkeys crossing the road which you can see in the picture below. Click on it for a better image of the turkeys.

Later in the week, we traveled up to Scranton and saw the Waymart Wind Farm which has 43 GE 1.5MW turbines.

I think that wind farms along the ridges of Pennsylvania will become a more common sight as time goes on. People should not consider wind turbines as eyesores, but rather see them as examples of majestic beauty that benefit all of society.

I believe people will come to understand we need to eliminate our dependence on exhaustible fuels to provide our electricity. There is no argument that we will run out of them eventually. At some point people will realize that when they turn on a light, a TV, or computer, the energy may be coming from a silent wind turbine spinning in the distance powered by a clean and inexhaustible energy source.

What really happened at Enron?

Share

The word Enron is now nearly synonymous with corporate misgovernance. But what really happened there? It’s easy to remember the news sound bites, but those seemed to address only the more egregious and sensationalistic aspects of the debacle. Namely, they focused on rich corporate executives plundering a company while at the same time the investors and employees were left with nothing. Is that really what happened? Yes, that did happen, but if that’s the only lesson we take away from it, we’ll have missed the real reasons behind what went on there.

I recently saw a movie and later read several books about Enron. The movie entitled Enron: The Smartest Guys in the Room, was based on a book by the same name by Bethany McLean and Peter Elkind. The other books were entitled Power Failure: The Inside Story of the Collapse of Enron by Mimi Schwartz and Sherron Watkins and Conspiracy of Fools: A True Story by Kurt Eichenwald. Between them all, they paint a story that you won’t get from reading just one of the books or by watching the movie. Terri saw the movie and read the books as well and she felt the same way. Reading about Enron is like watching a train wreck. It is hard to look away.

Can what happened at Enron be traced to a single root cause? I think it can. The root cause of the most spectacular bankruptcy in the history of business can be distilled down to one key issue. And that is that the reward system within Enron was not aligned with the long term financial health of the company.

The system at Enron rewarded executives who did ‘deals’ with large bonuses and, in some cases, an equity stake based on the absolute size of the deal, not on how well it served the long term financial goals of the company. As a result of this policy, several executives walked away with many millions of dollars in personal wealth after helping to sew the seeds of Enron’s destruction. Despite the size of their financial windfalls, these people seemed like minor players in the affair, partly because they were gone from the company before Enron’s collapse. Those held most responsible for the actual collapse, and whose names were mentioned in all the news reports, were primarily Ken Lay and Jeff Skilling. They are certainly culpable for their part in fostering a culture that encouraged behaviors that were at odds with the investors’ and employees’ long term interests. But they steadfastly maintained their innocence, thinking what had happened on their watch was nothing more than a ‘run on the bank’, or the fault of their subordinates, and that they personally felt company was actually still financially healthy. But the balance sheet told quite a different story. They just weren’t really paying attention to it. Whether they believed their testimony or not is anyone’s guess, but they were the ones in charge and thus needed to be held accountable for the malfeasance of their underlings. Both of them had been warned on numerous occasions about accounting irregularities and both tended to defend, deny, or ignore the warning signs.

When executives are awarded sizable stock grants and stock options, it can cloud their judgment. There are a number of ways to get a stock to increase in value temporarily while at the same time jeopardizing the long term financial health of a company. A few of the more notable accounting tricks used at Enron were counting profits years before they were actually due to accrue and hiding expenses in off-balance sheet entities. These two techniques, which go against everything a reasonably intelligent person should understand at an early age, were the most damaging accounting frauds perpetrated at Enron. These accounting techniques skirted legalities while flouting any semblance of sound fiduciary judgment.

In addition to these accounting irregularities there was a perceived need to expand the company at any expense and so a lot of money was poured into risky third world energy projects which ended up losing hundreds of millions of dollars. This was unrelated to the fake accounting, yet still an important factor in Enron’s eventual demise. It was the executives’ reward system in striking these deals that caused them to get involved in questionable ventures where their own personal wealth would increase even if the deals went sour afterwards.

Another thing that wasn’t necessarily responsible for the company’s financial woes, but did expose Enron’s toxic culture, was traders’ willingness to engage in schemes to bilk the California out of billions of dollars by exploiting some flawed deregulation laws that left that state exposed. This blatant disregard for ethics exposed a rather laissez faire attitude on the part of the management as long as lots of money was rolling in. The movie features incriminating audio recordings of Enron traders conspiring to overcharge for power using schemes with self-incriminating names such as ‘Death Star’ ‘Fat Boy’, and ‘Ricochet’. Again, this alone did not bring down Enron, but it certainly exposed and reinforced the absence of ethics that permeated the company.

I think that these books about Enron should be required reading for all corporate executives and the story of Enron should be a mandatory case study for all MBA programs as a cautionary tale. I found the stories behind the fall of Enron to be as fascinating as they were educational.

Motorcycle hazards

Silvio at the Splugen Pass near the Swiss border

I got an email from my friend Silvio in Monza to tell me that he crashed his motorcycle last week and hurt his knee. He thinks it will be a few weeks before he is able to walk on it again. I wrote about Silvio in the blog last summer when we visited Italy. We spent a day motorcycling in the Italian and Swiss Alps. He had loaned us his Honda VFR (the same one that was involved in the crash) and we had a great time riding it. I know this his lovely wife, Luisa, reads this blog and so please tell Silvio to get well soon and to be careful on that bike. He needs to stop scraping his footpegs around the turns because you never know when there will be gravel on the road.

Bill Dube with the Killacycle

Today I came across a story about the inventor of the Killacycle, Bill Dube, nearly getting killed while demonstrating it. The Killacycle is an electric drag racing bike with the equivalent of 400 HP. It goes from 0 to 60 mph in less than 1 second. This is going to be one of those videos that gets viewed millions of times, and his sponsor, A123 Systems, will get a lot of free publicity as a result. It appears that it’s already crashing the server at TGDaily.com. It may be time to put it on YouTube. It turns out that Bill got scraped up, but is otherwise OK. I found out he must live not far from me, because Killacycle is based in Denver. It appears that he’s also an experimental airplane enthusiast because he designed some LED position light kits that he sells on the same website that hosts the Killacycle information.

Terri’s Ducati is for sale

The last hazard I have related to motorcycles is that of swapping bikes with someone. A few weeks ago Terri and I were out riding and she swapped her Ducati Monster for my BMW R1150RT. Previously she had never ridden the BMW on the highway and she quickly became accustomed to the comfort of riding behind a streamlined fairing, especially when the weather turns cool and it begins raining. The end result is that the Ducati Monster is now for sale and she’ll be looking for something more like the Beemer for her next bike.

Cozy spar and wings status

Share

Here’s a short posting to show some of the progress on the Cozy. The Cozy was derived from the LongEZ and uses identical construction techniques. The main difference is that it is a 4-place airplane whereas the LongEZ is a 2-place.

This is the jig in which the main spar is built. The main spar is a box beam that is very strong. The wings attach to the spar and it is a major structural component of the airframe.

The part that makes up the shape of the spar is just foam, but it’s covered with many layers of fiberglass and epoxy which give it tremendous strength.

The wings are made of foam, fiberglass and epoxy. The shape of the wing is cut using airfoil templates with a ‘hot wire’ saw to give it an airfoil shape. This is probably the most fun part of building a composite airplane. In just a few minutes you go from a block of foam to something that looks like it belongs on an airplane.

The wing needs to be assembled in a jig to maintain proper dimensions. The jig also helps to set the sweep and twist of the airfoil.
