Samso: World's Most Inspiring Renewable Energy-Powered Island

Wade Lyman, a College of the Atlantic human ecology major from Bar Harbor, spent his formative years developing a deep appreciation for the natural world—and a deep fear of the possibility of ecological collapse. “I hope that involving myself in this cooperative sustainability effort with the Samso course is a good way to rapidly develop and refine a skill set that can be applied to a career in sustainable development. I’m particularly interested in energy storage and smart grid technologies, as well as heating and cooling, especially in difficult climates."

[Editor's note: This fall, 13 students and two faculty members from College of the Atlantic visited Denmark's island of Samso, the world's first island to be 100 percent powered by renewable energy. Here's an article by one of the students that visited Samso.]

Considering Samso's reputation as the home of perhaps one of the most inspiring renewable energy projects in the world, it's very encouraging to leave it with a sense of normalcy.

Very early on in the course, I got the sense that apart from the initial costs of the energy projects there were no deviations from normal life associated with the switch to renewables. Their goal was simple: replace fossil sources of energy for electricity, heat and transportation with tried-and-true renewables; and that's precisely what they did.

While quite remarkable in many respects, Samso's energy project is most noteworthy in that it was achieved by un-extraordinary means.

A local electrician on Samso expressed the idea clearly: "We don't necessarily do anything different here on Samso, we just provide people with more information about existing energy solutions and actually use the available technology and subsidies."

I was surprised by the visual subtlety of Samso's sustainability measures.

There were no major innovations, no ground breaking technologies developed for the move toward decarbonization, even the scale of the projects seemed surprisingly unobtrusive. Instead, 11 land-based wind turbines—each harnessing enough power for 600 homes—provide comprehensive electricity for the entire island, and several district heating plants provide heat and hot water for most of the homes and businesses. The rest is covered by several municipal- and privately-owned solar installations, heat pumps and wood stoves.

The transportation sector, which comprises Samso's most energy intensive investments (including a ferry that runs constantly, year round), is more than offset by 10 offshore wind turbines.

When reading about Samso, the idea of 21 sky-scraping turbines seemed insufferably obtrusive and loud, but I changed my opinion when I actually experienced it. Although they were very conspicuous, it was clear that the amount of power they generated was well worth any negative visual impact they might have on the landscape. And as for their impact on the soundscape, I stood right beneath them in a roaring wind and found their noise subtle and rhythmic—easily ignored.

A local couple in the Samso community told me that most of the negative impacts of wind disappear when the people are allowed to invest in the projects themselves. They explained that they were among the community members investing in a turbine adjacent to their driveway.

Now that they associate the turbines with economic gain, it doesn't look at all like an eye sore, instead it "looks like a sculpture and sounds like music."

In my opinion, even without financial compensation, the turbines instill a sense of security. The knowledge of their tremendous power—providing energy for 600 Danish homes—is substantiated by their impressive aesthetic, which ultimately leaves me with hope for eventual freedom from fossil fuels. That alone makes them worth it.

Seeing such a dramatic switch to wind power makes me wonder how social resistance to the technology was overcome, given that many people in the U.S. seem unconditionally opposed to wind turbines.

The courageous leaders of the Samso Energy Academy, Soren Hermansen and Malena Lunden, described a long struggle and democratic discussion replete with social nuances and disagreements that eventually led to a project that most community members could agree on.

After spending three weeks on the island and having discussions with the local community, it is clear that wind was the dominant renewable resource available and that Samso may have been  particularly well suited both logistically and culturally for wind as opposed to solar as a main power source.

On Samso, the strong east winds seldom stop, and on several hilltops stand the archaic remains of long decommissioned windmills. Turbines are thus seen as a part of the cultural landscape—and the roots of this sentiment are deep and resilient.

In past centuries, the windmills of Samso were the axle of the community's wheel; the landscape was stippled with more than 100 turbines, which drove the grindstones that partly defined the local food system and economy.

It seems that the community of Samso may have been primed for wind projects, but how much of a role this cultural history played was unclear to me.

Car Pollution Is Killing Coho Salmon

The grisly video above shows a coho salmon struggling to survive in polluted stormwater runoff on the Duwamish River in Washington. This contaminated water—filled with oil from cars, pesticides, dirt and debris—can kill this particular species of Pacific salmon in hours, according to Puget Soundkeeper Alliance, which posted the clip on Oct. 21.

Sadly, it appears that this fish is one of many coho salmon in the Puget Sound Basin that have died, and will continue to die, from this man-made tragedy.

The Tragic Tale of Tony the Truck Stop Tiger

By Stephen Wells

For more than six years, the Animal Legal Defense Fund fought tirelessly to save a tiger named Tony from a cage in the parking lot of a Louisiana truck stop. Sadly, we received news last week that Tony had died of kidney failure after spending 16 years confined to his cage, living and dying as a roadside attraction. Tony's plight is a microcosm of the problems with our legal system, a system that treats sentient beings as property and affords disproportionate political influence to their captors and abusers.

Tony was born into captivity, sentenced from birth to a life of exploitation, a gimmick used by his owner Michael Sandlin to sell gasoline at the Tiger Truck Stop. It doesn't take a degree in veterinary medicine to know that a truck stop is no place for a tiger. But veterinarians and animal behaviorists weighed in emphatically on Tony's behalf. Dr. Jennifer Conrad, a doctor of veterinary medicine with decades of experience with captive large cats, personally visited Tony and concluded that he was "exploited to the detriment of his welfare."

'Landmark Decision' Casts Youth as Official Intervenors in Pipeline Case

By Frank Jossi

In what is regarded as an unusual step, a group of 13 young people have joined together to become court sanctioned intervenors as they fight a proposed Enbridge Energy pipeline through northern Minnesota.

Intervenors are sanctioned by the state Public Utilities Commission to represent parties in contested cases. They are generally lawyers and experts hired by energy firms, clean energy organizations, environmental groups, governmental agencies and an occasional citizen or two.

Solar Power Forecast: Record-Low Costs Expected to Keep Plummeting as Technology Improves

The already-plummeting costs of installing solar power could fall an additional 60 percent over the next decade, the head of the International Renewable Energy Agency (IRENA) said Monday.

IRENA director general Adnan Amin told Reuters that the organization expects an additional 80 to 90 GW of solar capacity will be added worldwide each year for the next five to six years, and that improvements in technology, including batteries, will help drive down costs.

Report: EPA Hires 12 More Bodyguards for Pruitt, Costing $2M Annually for Full Security Team

The U.S. Environmental Protection Agency (EPA) Administrator Scott Pruitt has been noted for taking unusual steps to operate with extreme caution at the job—including the installation of a $25,000 soundproof communications booth and contravening a bi-partisan EPA transparency practice of keeping his schedule secret.

Now, CNN reports, the EPA is expanding Pruitt's security detail with an additional 12 agents, meaning his total security fleet stands at 30 bodyguards. This will cost the department $2 million a year in salaries alone and does not include training, equipment or travel.

Offshore Oil Drilling May Be Coming to a Coastline Near You

By Pete Stauffer

It's nearly impossible to convince certain people, most notably leaders of our federal administration, that bold action is needed on climate change, but recent events have certainly made a compelling case.

Three major hurricanes have battered U.S. coasts in recent months, impacting the lives of millions of people and causing billions of dollars in damage. Although no single storm event can be blamed directly on climate change, scientific experts agree that the warming climate and ocean waters contribute to the frequency and scale of hurricanes—putting the residents, natural resources and economic security of coastal communities at elevated risk. This makes the Trump administration's proposal to expand offshore oil drilling off U.S. coasts all the more dubious.

'We Are Not OK': A First-Hand Account of Hurricane Maria

By Cathy Mazak

I'm so happy to be able to communicate with you again. As many of you know, I live in western Puerto Rico. In this post I want to tell you a little about my family's experience with Maria, and how you can help Puerto Rico.

On Thursday Sept. 21, when the sun came up, I looked out our front door at a wintery landscape. There was not one leaf on one tree in all the tropical forest that surrounds our property. Instead, the walls of my house were plastered with one-inch-by-one-inch pieces of leaves. It was as if they had been stripped off the trees, chopped in a food processor, and coated onto our house with a pressure washer.
