Samsø is 100% self-sufficient using only renewable energy sources

Once completely dependent on oil, Samsø is now self-sufficient in electricity (it produces 140% of its needs) and covers 70% of its heat requirements.

The Danish island of 4100 inhabitant gets its electricity and heating tanks to a network of wind turbines, solar panels and biomass funcions.. 11 onshore wind turbines of 1 MW have been financed by local residents, and 10 offshore wind turbineshave been set off the island's coast. The island has also about fifty photovoltaic plants and several biomass power plants fueled by wood, straw, as well as household waste sorting.

This ambitious challenge has been taken up in 10 years by the inhabitants and was coordinated by Energiakademiet that brings together the latest knowledge on renewable energy technologies.

Environmental work on the island has created 30 new permanent jobs according to Samsø Energiakademiet and helped to fight against depopulation.


The community's aim is to be rid of fossil fuels entirely by 2030.


Activities and leisures

Every summer, sea trips are organized onboard M/S Tunø traditional wooden boat to watch the seal colony that lives on Bosserne reef off Samsø

Geographic strenghts

Samsø is a Danish island of 114 square kilometers located in the heart of Scandinavia, in the Kattegat Sea. Once popular for its agriculture, and more especially for its potatoes and strawberries, the island is now internationally  renowned for its self-sufficient community in renewable energy. Secluded and of small extent, the island of 4,100 inhabitants offers an ideal ground to carry out a sustainable EU policy experience and energy engineering. Not to mention that the island is flat and swept by winds.

The island is prized by tourists for its bucolic landscapes, beaches with clear water, walking and cycling paths, picturesque villages with beautiful colorful houses and elegant Protestant churches.

If Samsø is a model regarding energy consumption, it is not ranked among Top ecological islands, especially concerning intensive agriculture and pesticide use. However, organic farming slowly but surely emerges and some small retail outlets open to the public all year round.

Environmental background

In october 1997, Samso won a competition launched by the Denmark’s Minister for the Environment asking local communities or islands to present a plan for a transition to self-sufficiency through renewable energy. Ten years later, Samso was generating more electricity from renewable energy than it consumed, mainly from 11 onshore and 10 offshore wind turbines, totaling 34 megawatts and central heatings. Samso’s CO2 footprint is negative 15 tons per inhabitant, which includes the 10 offshore turbines that were built to compensate for carbon emissions from the transportation sector.

Samso’s longterm goal is to be a fossil free island, phasing out oil, gas and coal by 2030. According to Energy Academy, the success of the island project is based on its bottom up approach. Nine of the 11 onshore wind turbines were bought by farmers, and the remaining two bought by more than 500 islanders. Each 1 megawatt wind turbine powers approximately 630 homes. 

Samso green revolution is a success today thanks to the local community which benfit from national and European funds, and preferential and guaranteed rates fixed by the State. Investments are therefore amortized on less than seven years. Samso has become a global example of how to create a sustainable community through local ownership and community engagement.

Maritime economic background

Because of its central geographic location, Samsø has been the center of the Viking Era for several centuries (sams = collective and ø = island).

1 400 years ago, the island was used as a meeting point for Vikings fleets that gathered there annually and has become the major site of recruiting warriors. Archaeological sites prove the old building castles erections and the canal, dug to facilitate the monitoring of all vessels from the south, can be easily seen from the main road leading north of the island.
The Kingdom of Denmark was formed from Samsø, which controlled at this time much of the Scandinavian islands and fertile land. Ref: The story of the Vikings (about 700 AD to about 1200 AD) by Karl Rasmussen.

New Caledonia: inventory of unknown biodiversity

An inventory of Caledonian biodiversity is being conducted by the National Museum of Natural History (MNHN) and the NGO International Pro-Natura within The Revisited Planet's program. If the archipelago is known for having the highest levels of endemism in the world, small animals remains unknown. During two years scientists will crisscross forests, rivers, mountains and seabed to discover new species.

Ouessant put on agricultural recovery in the fight against wasteland

Ouessant and Armorique Regional Park are launching a call for candidates within the development of innovative and eco-friendly agricultural projects. Farming will help to revitalize and highlight the island while generating employment opportunities and mixing tourism local products development.

Atlantic: draft of whale sanctuary scuddled

At the 66th meeting of the International Whaling Commission held currently in Slovenia, pro-whaling countries have again scuttled a whale sanctuary's proposal in South Atlantic. A disappointing sign of the continued political influence of Japan that pursues commercial whaling under the guise of so called scientific research.

Saguenay-Saint-Laurent Park : whale watching strengthened rules

The many users of the Saguenay St. Laurent Marine Park will have to respect new rules from January 2017. The new measures include the prohibition of jet skis and other motorized pleasure craft and the strengthening of behaviour in the presence of endangered species, such as beluga whales in the St. Laurent.

TripAdvisor boycotts attractions with wild animals

Tourist activities where tourists come in physical contact with captive wild animals or endangered species are becoming "has been" thanks to Tripadvisor. Highly influential, the world's largest travel site announced it stops selling tickets for these activities and intends to launch an educational website dedicated to tourism with animals.

Moorea: the biophonie, a persuasive tool for underwater monitoring

Following four months of records, scientists from Island Research Centre and Environment Observatory (Criobe) in Moorea demonstrated that underwater acoustics is very efficient to identify healthy environment and that marine protected areas are effective. A monitoring has been conducted in four MPAs of the island and four non-protected areas, and has clearly helped to differentiate the two.

Scotland: the largest protection area for porpoises in Europe

The Scottish Government has confirmed the creation of a Special Area of Conservation (SAC) of 13,540 km2 in the Hebrides for the harbor porpoise (Phocoena phocoena) which is a protected species. If porpoises are still the most common cetaceans in European waters and around the UK, their numbers tend to decline because of marine pollution and drowning related incidental catches.
