2nd Green Revolution - Part 7

Out with the New in with the Old

A few months back I had the opportunity to tour three LEED certified projects on three consecutive days. All three projects achieved LEED gold and were located in the greater Denver area. The following op-ed is a bit of a reflection on these visits and what it means to build green. They are listed in reverse chronological order to demonstrate the lessons I learned.

The school I visited sits on a 35-acre parcel of land located off the road leading to the airport. Prior to the school, there were no buildings on the site. I believe it was a meadow. This type of development, often referred to as greenfield – because it builds on previously undeveloped land – is often associated with sprawl. Brownfield development – land that was previously developed – often fills in pockets of underutilized land, helping to increase density.

My second visit was to the EPA’s Region 8 headquarters in Denver. This building sits on the grounds of the formal postal annex which was constructed in 1959 and before that a warehouse similar to one that still stands across the street and houses the Alliance Center for Sustainable Colorado. While the new EPA building is a beautiful, gleaming structure with lots of natural light, it does not change the fact that there have been three buildings over the same time frame that another one, currently LEED-certified former warehouse, has stood across the street.

The warehouse was the first building I visited chronologically

Not Your Average Bus Trip: How “Green” is that Green Bus? Part 4

Around the beginning of August, with our bus fully functional again, and about halfway through our adventure, I had ample time to process this whole biofuel phenomenon.  As brought to my attention originally by my father, who would send me periodic articles on the topic, in addition to me personally offering explanations to curious people across the nation, I had begun to realize the downsides of biofuel as a solution to our reliance on fossil fuels for transportation.

The first disturbing issue was the massive deforestation of rainforests already occurring in order to grow crops for biofuel.  According to the United Nations Environment Programme, clearing tropical forests for biodiesel production can actually lead to an overall carbon debt compared to the savings from using biofuel as opposed to fossil fuel for transportation (Working Group on Biofuels of the International Panel for Sustainable Resource Management, 2009).  Of particular concern are tropical countries where agricultural yields are high, such as Indonesia and Brazil.  “If current trends continue, in 2030 the total rainforest area of Indonesia will have been reduced by 29% as compared to 2005, and would only cover about 49% of its original area from 1990” (Working Group on Biofuels).

Another area of great concern is the Amazonia in Brazil, where in addition to its irreplaceable biodiversity, according to demand projections by 2020, the “expanding landscapes of renewable energy, in concert with a growing cattle herd, could require land in excess of what conservation policy has provided, in little over a decade” (Walker, 2011, sec. 4). Compounding other concerns about loss of biodiversity, food security, and impact on water resources, another huge environmental problem exacerbated by the increase in biofuel demand is eutrophication, caused by the leaching of excess nitrogen and phosphate from fertilizers, leading to the overproduction of plant biomass.

Five Friday Facts: Vermicomposting

We’ve had a several posts on composting, including one on an experiment with worm or vermicomposting. Some advantages to composting with worms (if you aren’t squeamish) is that they convert the waste to rich, usable soil faster than conventional methods. Also, because the castings from the worms have a mucous coating, the nutrients are released into the soil over time instead of right away. Here are a few other interesting bits about the little guys and the work they do.

New Year’s Resolutions

For the past few years I have been trying to take steps to be more sustainable.  It started when I was an undergraduate and joined the campus environmental group.  Recycling has always been a habit, so it wasn’t something I had to change.  I did begin riding my bike and walking everywhere possible; a college town made this easily possible.  Thank you Manhattan, KS. I then dabbled with being a vegetarian- which lasted around 3 years.  I still stick to only one meal a week that has meat.  I then started taking a closer look at what I was eating, and started to stray from packaged food.  Then began considering organic, local, seasonal foods.  Those principles have all stuck to a degree.

So this year what else can I add? I always feel I can do better to be more sustainable.  So here are my New Year’s Resolutions:

2012 Consumer Electronics Show to Highlight Green Tech

Each year, the Consumer Electronics Association (CEA) holds the international Consumer Electronics Show (CES) to promote growth and innovation within the consumer technology industry. Since it is the largest, and greenest, technology tradeshow in the world, we’re very excited to see what environmentally-friendly and energy-saving products will be unveiled at this year’s show, to be held January 10-13.

The eco-friendly products being promoted by companies at the tradeshow will be featured in two green exhibits. The first is the Sustainable Planet TechZone, which includes 24 companies, up from just ten in 2008. Though several of the businesses in this group specialize in electronics recycling and efficiency compliance, others may unveil some new, more fascinating products. A few companies that caught my eye were

British Firm Doubles Up with Solar/Wave Power Combo

Wouldn’t it be nice to harness the power from all that turbulence in the seas? There are numerous startups working to try to perfect a technique to do just that from waves and tides. What if you could add a solar powered top to that device, creating the ability to harness both sun and sea?

Marine Solar Cells is attempting such a double. The British company led by Phil Pauley makes a hybrid solar and wave energy generator that “captures both wave energy through natural buoyancy displacement and solar energy through photovoltaic cells as natural sun light also reflects from the surface water to increase solar capture by 20%.” Definitely out there, the device is still in the conceptual design stage. However, from the photos below, you can tell that the idea is starting to take shape.

Devices that can generate energy in more than one way or demonstrate other efficiencies are key to the future of a sustainable economy. Some will fail but some will prevail, pushing us toward balance.

Seattle Joins Washington DC in Banning Plastic Bags

Effective in July 2012, plastic bags will be banned in Seattle. This marks the latest in a series of plastic bag bans. Last year California attempted to pass a statewide ban, but to no avail. However, Washington DC has had a ban in place for a few years now. For a list of the pros and cons of both paper and plastic bags, click here.

NPR reports that there is “a provision to charge a nickel fee for the use of paper bags.” The Seattle Post Intelligencer mentions that this is the city’s second foray in the bag ban. “In 2008, after the Council adoped a 20-cent fee on the bags, the plastics industry spent $1.4 million to crush the measure. Voters repealed the fee in 2009.”

The ban is fairly comprehensive.

Christo Projects Are Awesome, But Use the $50 Million for Something Else

From the art world comes the latest wild idea from Christo, the artist who has wrapped trees and draped orange awnings on a winding path through New York City’s Central Park. Last month, federal regulators gave the go-ahead for a $50 million project to install an enormous piece of fabric over the Arkansas River in southern Colorado. As the New York Times reports, “Over the River will include eight suspended panel segments totaling 5.9 miles along a 42-mile stretch of the river, about three hours southwest of Denver. Construction could begin next year, pending final local approvals, with the goal being a two-week display of the work as early as August 2014.”

While the project could generate over $100 million in economic output and bring up to 400,000 tourists to watch the construction and then look at the actually display, the project was held up over environmental and aesthetic concerns. A few points of contention included “road safety in the narrow canyon highway through the installation zone, which extends from the towns of Salida to Cañon City, to potential impacts on wildlife, especially on the Rocky Mountain bighorn sheep that habituate the Arkansas River canyon and are Colorado’s state mammal.”

The projects Christo comes up with are often memorable and quite interesting. However,
