Wind turbine timing saves bats

The popular wisdom tells us that bats can "see" anything in the dark, thanks to their remarkable sonar. Well, apparently, that doesn't apply to wind turbines.

The mix between clean energy generating wind mills (or wind turbines) and these tiny winged mammals has been deadly. A study performed by the Bats and Wind Energy Cooperative (yes, that is for real...trust me, I could not make that up) found that as wind power has increased in popularity, so have bat fatalities. Turning the wind turbines off at night if the wind is low (bats' favorite time to be out and about) resulted in a nearly 79% drop in the number of bat deaths.

(Okay, forgive me here, folks. I like bats. I really do. I had a big barn in Pennsylvania that was partially leased to a neighbor, and when I found out he was planning to put moth balls in the lofts to get rid of the bats, I threatened to remove all of his stuff and revoke the lease! I used to watch the bats come out at dusk...so I really do like them. But somehow, with this story, I keep getting images of old Batman episodes and Batman and Robin coming out of the Batcave and hitting into a giant windmill placed there by the Joker or Penguin or some other arch enemy...doesn't help that the sources I'm using also talk about bird deaths, and that brings to mind Robin...Anyhow, forgive me if I stray, because I know this is an important topic but I needed to warn you in case my subconscious gets the better of me and inserts a pun or two...)

Bats are critical to the environment, as a primary control on the insect population. No bats, lots more bugs. And clean energy is critical to our environment, too. Wind turbines are an excellent and affordable choice for energy. We need to get beyond oil. So the deadly clash between the two is a major concern for both environmentalists and clean energy producers.

Scientists are studying the reason for the problem, as they aren't sure whether the bats can't see the spinning blades, which can reach speeds of up to 180 miles per hour, or if they are attracted to the shiny metal in the blade itself. There is also some concern that the movement of air around the blades may be interfering with the bats' sonar or even affecting their lungs because of the significant changes in air pressure around a turbine (think divers and the bends.)

Experiments are being conducted to create sonar barriers or physical barriers around the blades to protect the bats. For now, turning the turbines off on low wind night seems to be the best choice, and one that most clean energy producers are willing to try.

Green your computers with Wake on LAN

You want to save energy at your company and at home, but there are updates you need, remote access that's essential or data that needs to be accepted even during times when no one is around.

So do you leave the computer running, sucking up energy and waiting? Or do you miss out on the updates and access?

There is a third choice, and odds are it's already built into you computer. The process is called Wake on LAN. In plain English, it means that even if your computer is in energy-saving hibernate or sleep mode, it can wake up and accept data or allow access even when no one is around to press a button.

There's a complete step-by-step of the process on Lifehacker, but basically it's as simple as making a few tweaks in your computer's BIOS settings, then changes the settings in the Device Manager to allow your computer to utilize the new BIOS.

Best of all, after your computer has stretched its virtual arms and accepted your remote access or incoming data, you can tell it to go back to sleep (or into hibernate) again until the next update.

A free PsShutdown tool from Microsoft SysInternals can be used to script automatic standby after each use.

The whole process will take less than 10 minutes to install, but the energy savings, especially for a large company running PC's at every desk can be enormous. Who said becomig a greener business was hard?

Scotland plans on 50% renewable fuel by 2020

In an ambitious plan to recover lost jobs and reduce oil energy dependence, Scotland is actively pursing plans to harness an abundant natural resource...the wind...as a primary energy source.

According to the Wall Street Journal, Scottish representatives were at a wind power conference in Chicago last week, seeking suppliers and interest for large off-shore wind power rigs. The hope is the move will boost employment and help Scotland gain access to low-impact power sources.

According to Wikipedia,

Wind power in Scotland is an area of considerable activity, with 1550 MW of installed capacity as at October 2008.[1] Wind power is the fastest growing of the renewable energy technologies in Scotland and the world's largest wind turbine generator (5 MW) is currently undergoing testing in the North Sea, 15 miles off the east coast. There are numerous large wind farms as well as a number, both planned and operating, which are in community ownership. The siting of turbines is sometimes an issue, but surveys have shown high levels of community acceptance for wind power in Scotland. There is further potential for expansion, especially offshore, given the high average wind speeds.

And a 2005 map of Scotland's energy plans shows over 250 proposed wind power sites nationwide.

I can't help but wonder why the U.S. hasn't followed suit for our own power needs. I know some companies out there, like Green Energy Prod, are offering wind turbine systems, but I am not seeing them in action. Any ideas on how we can encourage that same type of innovation here?

Green holiday cards big business for businesses

In a recent survey of business owners, 40% said that the environmental aspects of the holiday cards and other business greeting cards they send out matters "somewhat" or "very much." That's up from just over 29% two years ago.

The same survey showed that 52% of businesses are using some form of green business practices with regard to paper choices and disposal within the company, an increase of nearly 30% over the previous survey.

The survey did not evaluate whether the owners were willing to pay more for the cards, or whether they were using green business practices in other, non-paper areas of their companies.

Organic produce production, sales down

The other night in the grocery store, I heard no less that a half a dozen people on their cell phones talking to other people (at home?) asking whether to buy this that based on price. And the differences were usually well less than a dollar. Sometimes, I watched them put down both options and walk away.

Times are tough. The recession/depression has people watching every dollar. And one area especially hard hit is organic produce and organic food products.

Michael Smith, blogger at Green (Living) Review, was discussing the fact that sales of organic produce and other organic foods are dropping. Many farmers, he reports, are returning to "cheaper" standard production methods. Consumers, when faced with two cans of beans or bunches of grapes, are opting for the "regular" version over the double-the-price organic one.

It's not that we don't want organics. We all know they're healthier. But we just can't pay the premiums growers and retailers are demanding for that often ambiguous organic label.

Those of you who have been reading this blog for awhile will remember that I spent a few posts talking about this very issue. Green companies pricing themselves right out of the marketplace. I was talking about t-shirts, notebooks and baby blankets, but the concept is the same.

If the current economic trend continues, will organic food continue to grace our supermarket shelves in large quantities? Will producers and marketers see the writing on the wall (or on the balance sheet) and work to bring prices in line? Or are the days of organics everywhere numbered?

Eco-labeling - Can consumers sort out the hype from the facts?

According to Joshua Saunders at GreenBiz.com, there are now over 300 different so-called eco-labels in use in North America alone. Sounds good, right? All that information for consumers and business buyers who want to make the most environmentally friendly choice in their shopping decisions. Except:

• Most consumers, including B2B shoppers, don't understand more than a few of the most basic labels
  
  
• Even when they do understand them, having a high score on one green factor doesn't necessarily mean the product is better for the environment than a similar item without that factor. (For instance, a product may contain a high percentage of recycled material, but the process needed to transport and reuse that product may leave a larger carbon footprint than a locally made virgin materials product.)
  
  
• When faced with two or more different types of eco-labels on similar products, consumers have no idea which green element is more significant
  
  
• Many misleading or ill-defined labels are in use
  
  
• Enforcement of many labels is non-existent. In fact, many companies are self-certifying their products as "green" or "environmentally friendly" with no data to back that up. This so-called "greenwashing" is on the rise.
  
  
• Useful information about the real environmental costs of a product or service over its useful lifetime are expensive and difficult to measure. Small to medium sized companies simply cannot afford the invest of time or money needed to generate that data.
  
  
• Even basic titles like "organic" which was supposed to be defined once and for all by federal legislation continues to be fuzzy. State, local and industry standards for organic products remain in use, and are in fact, increasing.
  

So what is a consumer or a business to do?

Educate yourself.

• Start with ecolabeling.org for a some good guidelines on what all the labels really mean.
  
  
• Look for trusted labels like the California Organic Certification or the National Forest Service's Forest Stewardship Counsel logo.
  
  
• Learn about the benefits and environmental costs of various green factors, so you can make rational choices when faced with multiple labels.
