Wind turbines are a fast, efficient way to produce renewable energy. They’re good for the environment, the power grid, and local communities. But some residents who live closest to the turbines complain about the noise, and limited data suggests it might be more than a nuisance.

Wind turbines have grown quieter with improvements in technology, but the fact remains that they generate noise. At night in particular, the atmospheric conditions change so that turbines are more likely to generate audible sound. Beyond causing annoyance, some residents have started to complain about health effects. They claim to suffer from exposure to “infra-sound”.

This sound is so low that the human ear can’t detect it, but that’s doesn’t mean it can’t impact the human body. After all, we can’t see UVA or UVB light rays, but you feel them in a sunburn. The question is how and to what extent? Is it serious enough to be a concern?

This is where research into the topic becomes tricky. It’s one thing to find a report or article online that discusses the topic; it’s another to find reputable research that  provides (unbiased? conclusive?) evidence. It’s an emotional subject, so reliable information is hard to find. Some sources made nasty accusations against an opponent (government, industry, organization, etc.) without any evidence at all. The conclusions I was able to draw are pretty straightforward, and they fit nicely into two points. Read the rest of this entry »

My sister and I bought and assembled an electric motor for my dad’s bike this Christmas. It was the first gift he’s ever enjoyed from us.

Recently retired and now living in a suburb of St. Louis, we knew he’d never take to biking as there were a number of screw-this(!) sized hills all throughout his town. Through ten years of teaching I know that adults are far less resilient than children and often times need but one excuse to say “screw this” and go back , in this case, to a steady diet of TV watching. But we were elated to see how much he enjoyed his juiced up Electra Townie! Whether it’s riding with my mom (another proud new owner of an electric bike–she had to keep up), biking to the store for groceries, or putting it on the bike rack and hitting the Katy Trail, few days go by that he’s not on his electric bike.

This began my love affair with electric bikes.

30 steps to a more sustainable you!

7-22-2008. A quarter of a year has gone by since I posted my Earth Day blog offering 22 suggestions to change your lifestyle

Have you made any changes in the last 3 months?

I’ll trust that you have, and in case you’ve done so well that you’ve incorporated ALL 22 suggestions into your daily routine, I have added 8 more in this post (following the original 22) to make it an even 30.

After going through the list please use the comments section to add to my list and/or to explain why you’ve done so well (or poorly) in the last 3 months.

From Earth Day post:
1. Buy a rain barrel. You can’t drink the collected water, but you can water your lawn and wash your car with it. You’ll save thousands of gallons per year in the process!
2. Turn off your TV!!! At least limit your TV watching!
3. Drive less. Walk, bike, skip, skate, and stroll, more. This way you can get some fresh air while running an errand, and you’ll feel (and look) better in the long run.
4. Use natural fertilizers on your lawn and garden. Harsh chemicals found in conventional fertilizers are bad for your lawn and all who play on it. Also, it harms our groundwater supply.
5. Replace old bulbs with CFL’s and/or LED’s.

It started with a long discussion betweeen my wife and me. We each thought it’d be fun to get a scooter, but worried that, for us–a 1 car, 2 bike family–we would actually be doing more environmental damage by getting a scooter. Meaning, unlike many who get a scooter to use instead of their car (wise choice), we’d end up using our scooter instead of our bikes (un-wise choice). Being our primary mode of transport, the bikes would likely fall victim to the newer, sexier, faster scooter.

This got me on the thought process that I wished more people would first give a bike a try for their short trips, instead of viewing the scooter as their only alternative to combat gas prices. Of course it’s more work–but more work can be more rewarding. Which got me to thinking that there are plenty of tools that have traded elbow grease for electricity–yet we have benefitted little. Which turned me on to this mini-series…

Just as John Henry fought the steam hammer to show that human power cannot be undone by the industrial revolution. I am hoping to open a few eyes to the alternatives that are possible when we replace one of our everyday machines with the same machine sans motor/electricity/etc.
In the interest of full disclosure John Henry did beat the steam hammer but he also dropped dead in the process.
That said, I will be realistic with my comparisons–I don’t want anybody to drop dead of exhaustion. I’m sure I’ll find, in some cases, the modern invention to be more beneficial to the manual powered version it replaced.

I’ve long had a theory that many people enjoy golf because of the picturesque surroundings of the typical golf course. Wooded areas, rolling hills, green grass, lakes and ponds, rivers and creeks, sand…sadly, it is the closest that many people will get to “nature”, and the longest chunk of time many are willing to spend outdoors. And although it is beautiful to behold–the average golf course maintains it’s beauty with a high dose of toxic chemicals–not to mention the enormous consumption of water (approx 18 million gallons per course per year), the clearcutting of woodlands and fields, and the loss of animal sanctuaries.
More and more golfers, hackers, and non-golfers are becoming aware of the environmental damage one golf course can have on its surroundings. In the case of George Prior and his family the article “Poisoned Fairways” points out how they learned the hardest way:

In August 1982, after a few rounds of golf at the Army Navy Country Club outside Washington, D.C., Navy Lt. George Prior, an athletic, healthy, 30-year-old Navy flight officer, developed an odd rash on his back and began suffering flu-like symptoms. He checked himself into Bethesda Naval Hospital, where his body soon began to burn from the inside out. His internal organs started failing, blisters bubbled on his skin. After slipping into a coma, he died within days. A Navy forensic pathologist concluded that Prior had died as a result of a severe allergic reaction to Daconil 2787, a fungicide that had been sprayed on the course.

Of course, this is an extreme case, but one that can be tracked to its source (mainly because Mr. Prior was in the armed forces and received a detailed autopsy) unlike many other similar, though less violent, cases. However, most chemicals don’t have such an immediate effect on the golfer or the environment, but the end result of prolonged exposure may be the same. Golf course pesticides and herbicides have been linked to repiratory problems, serious skin irritations, nausea, and cancer.

Change is on the horizon.

Neighborhood associations have applied pressure to keep golf courses (and the surrounding neighborhoods) chemical free. Models have joined to help keep pesticides off the shelves. And, organic golf courses are beginning to pop up.

In my home town of St. Louis, Missouri one company–Keeper of the Green–is helping golf courses create the same beauty and durability while using environmentally friendly products.

Truck stop electrification is boosting fuel efficiency and minimizing dependence on foreign oil from idling trucks

There are 1.3 million long-haul diesel trucks with sleeper cabs in the United States, with most drivers averaging over 100,000 miles annually. These trucks are highly affected by skyrocketing fuel prices and are dependent on foreign oil. As the value of the dollar diminishes, transportation costs are partly to blame.

Idling Trucks Waste Fuel

Truck drivers are required to rest for 10 hours for every 11 hours of driving. A large amount of fuel is consumed when drivers leave trucks idling to maintain comfort. 85% of the energy is wasted sleeper cabs are heated by an idling truck. It is even more inefficient to cool the sleeper cab, wasting 94% of the fuel’s energy.

A few thoughts and a cartoon popped into my head last week while reading an article in Grist on oil companies having to clean up contaminated groundwater. The article stated that

“Some of the nation’s largest oil companies will over the next 30 years have to pay to clean up groundwater befouled with gasoline additive MTBE. In settling a suit brought by 153 public water providers in 17 states, a dozen companies — including BP, Shell, ConocoPhillips, and Chevron — will also have to pay a total $423 million cash.”

Thought #1: Finally!
Thought #2: 30 years! How about 3? And how about shipping clean water to homes in the affected areas in the mean time?
The article goes on to state that the estimated cost of the cleanup is $30 billion…
Thought #3: Why $423 million then?! I’m taking that same logic with me next time I fill up my car. “What, the cost is $4 a gallon? I’ll pay $1.50.”
It also mentioned that Exxon Mobile (among others) did not agree to settle…
Cartoon #1: Big Oil’s Mess? It MTBE, It Could Be, It Is!
And,
Thought #4: How can 17 states worth of contaminated groundwater even be cleaned up?
That’s when discovered that a few University of Aberdeen researchers have found that a whiskey bi-product may just do the trick.

The Internet is so big, it’s easy to miss shopping resources, especially if you’re environmentally conscientious. Here’s an easy guide to green shopping online:

The Internet has revolutionized how we shop. Shopping has become an interesting intersection between society, economy, and technology. Its also an excellent place to find great deals. It used to be true that many green products were more expensive. Free trade? Organic? Recyclable? Post-Consumer? Get out the credit card and take a deep breath! But nowadays that’s not always true; in fact many green products are less expensive, or can save you a lot of money. That fact helps drive their popularity; so much so that even large corporations are taking efforts - or even pains - to go green. But with the mainstreaming green hype, we must beware greenwashing - misleading marketing or practices that lure consumers. On the flip side, buying stuff for the sake of stuff is not environmentally friendly either.

Green Companies:

It’s easy to know which companies are really making an effort.

National Green Pages: Co-op America provides the National Green Pages, which works like a phone book. Major brands include Patagonia, Seventh Generation, and Clif Bar; also features local stores.

LinksOrganic: an international guide to finding organic or environmentally-friendly businesses.

EcoMall: A 90s flash-back site with lots of great links for anything your heart desires.

Climate Counts: this site covers large corporations. It judges their carbon foot print and efforts to reduce it. It covers major brands in all product categories, but it does not cover individual products.

Green Peace Electronics Guide: similar to Climate Counts, covers large electronics corporations. Read the rest of this entry »

For years I’ve been reading about the benefits of a vegetarian lifestyle. Beef production creates more CO2 than autos, factory farm conditions are unhealthy and awful, and veggies are healthier too! But let me be frank: I really really really like bacon. I can cut down on my meat intake, no problem! I only eat it with friends and relatives. But say good bye to succulent chicken breast, or slow-cooked BBQ ribs… forever? Well there’s only so much a girl can do, my friends.

So I suppose it’s not surprising that some people are looking for meat alternatives, and I’m not talking about Tofurkey. I’m talking about real meat, but minus the animal. Read the rest of this entry »

Happy Earth Day to all!

This Earth Day let’s break it all down and see things for what they are.

Our world is in a state of climate chaos as a result of our conveniences. This CleanTechnica blog is an opportunity to see what is being done worldwide in the realm of clean technology (ie. renewable energy, alternative fuels, sustainable products and services etc…) so that we can keep these conveniences.

That’s terrific–I’m glad it is being done, but this Earth Day I’d like to say–F your conveniences!

Here are 22 (since it’s April 22nd) things you can do daily that are inconvenient but we would all benefit greatly if everyone did them. And, to be honest–they’re not that inconvenient. They may in fact be just inconvenient enough that when you do them you get the rewarding feeling that you are doing something to benefit the greater good (i.e. earth, and its many earthlings) besides simply donating to a charity once a year during the holiday season.

I know we live in a country full of citizens more excited that Starbucks has a drive-thru than Toyota has a Prius, and will not be truly satisfied until Starbucks has a video camera mounted a mile from its store so it can read your license plate to anticipate your arrival and have your drink ready for you by the time you get there. Then all you’d have to do is slow down enough for the “barista” to throw your “coffee” into your car as you rolled by with your window down. After all, complete stops are for suckers! I digress…

Those people are out there in large numbers–and they are probably not reading this blog, so it’s up to you to send it to them because these 22 inconveniences can change the world.
