Green Options

Ecovillages are great habitats and support systems for people who want to live environmentally friendlier, happier, healthier lives. One of the most famous modern ecovillages, Findhorn Ecovillage, starts this ecovillage spotlight series.

Ecovillages often combine ecological planning and design with innovative social, political and/or economic systems. Additionally, they often include certain cultural or spiritual goals.

The Global Ecovillage Network (GEN) states, “Ecovillages are urban or rural communities of people, who strive to integrate a supportive social environment with a low-impact way of life. To achieve this, they integrate various aspects of ecological design, permaculture, ecological building, green production, alternative energy, community building practices, and much more.”

Due to their great features but still rather obscure existence, I decided to do this “Ecovillage Spotlight” series to highlight some of the great ecovillages that exist around the world.

The ecovillages that follow show some of the great possibilities that are out there for ecologically friendly, community living.

Wave energy seems to be Scotland’s lottery number. Scotland-based energy developer Pelamis just signed a joint venture agreement with the European energy giant Vattenfall for a large, almost $100 million energy project off Scotland’s Shetland Islands. This follows the recent launch of Oyster, reportedly the largest working hydro-electric wave energy device in the world, by the Scottish government and partners.

This new project by Pelamis and Vattenfall is being named Aegir, named after a Norse mythological sea god. It is Scotland’s largest wave power scheme.

The largest working hydro-electric wave energy device was launched by Queen’s University Belfast, Aquamarine Power Ltd. and the Scottish government recently, bringing the global wave energy industry one major move forward.

The device is called Oyster. It is the only hydro-electric wave energy device producing power in the world, according to Queens University Belfast.

How does it work?

A new report, The Economics of Ecosystems and Biodiversity (TEEB), attempts to bring to the world’s attention the truly great economic value of ecosystems and biodiversity, as well as the benefits of taking these into account when making policies.

The value of the world’s natural ecosystems and biodiversity is something lacking in most economic analyses. Lack of value for what is truly priceless doesn’t just hurt the environment, however. It is also a sort of economic suicide. This new report, hosted by the United Nations Environment Programme and supported by key EU, UK, German, Swedish, Dutch, and Norwegian bodies, attempts to bring all of this to our attention more and show some positive case studies of how taking the environment into consideration can actually save us money.

As the report says: “the failure of markets to adequately consider the value of ecosystem services is of concern not only to environment, development and climate change ministries but also to finance, economics and business ministries.”

Two seperate scientific studies have revealed that global warming is leading to significant reductions in the size of sheep and fish species, more evidence that climate change is forcing a huge range of species to adapt to a hotter world.

The first study, published in the Proceedings of the National Academy of Sciences, investigated fish populations in French rivers and the Baltic Sea and discovered that fish are shrinking as their habitats heat up.

Results show that average fish size in many French rivers have declined over the last thirty years, while the geographical range of tiddlers in the Baltic expanded as species such as herring and sprat also shrunk.

A combination of energy efficiency and targeted growth in renewable energy generation, Scotland would be able to to generate 143% of its annual electricity demand.

Wild sheep on the island of Hirta off the shore of Scotland are smaller than 25 years ago, and scientists have found climate change to be the cause.

On average these wild sheep are weighing in at 5 percent smaller than 25 years ago, an indication that climate change can have a rapid effect on natural populations and a sign of possible more widespread changes in future, researchers said on Thursday.

Scotland plans to reduce its carbon emissions by 42 percent by 2020 from 1990 levels, the most by any country.

The BioMara research project investigating the feasibility of using microalgae and seaweed to produce biofuels was launched on Friday by Scotland’s Energy Minister, Jim Mather.

“Effectively, seaweed harvested off a beach in the Outer Isles could be heating a crofter’s kettle for their cup of tea the next morning.” - Laila Sadler, spokesperson for BioMara

Five activists managed to shut down a coal mine before being arrested and charged with “breach of the peace” for standing on a piece of equipment with a sign reading “No New Coal.”

“We’re here to send a message to [mining company] ATH Resources that mining the dirtiest fossil fuel and fuelling climate change is not acceptable,” said one activist. “As mining companies such as ATH don’t appear to be listening, we’ve come to stop them mining, too.”

Is creating a national park for the chief purpose of economic development a good idea? Or does it ultimately diminish the conservation value of other national parks?

That is what I asked myself after reading this article from the BBC, about how a western region of Scotland known as “Harris Island” is voting on whether or not to attempt to make the area a national park (Harris is not actually an island).

The area’s population has decreased by 25% over the last twenty years, prompting residents to search for methods to develop Harris’ economy and halt its declining population trend. Other than that, the BBC has provided little additional information.
