What is a sustainable island?
What is a sustainable island? A sustainable island can cover its needs for fresh air, solid wastes, nutrition and power with self-sufficient processing. More sustainable ways for the island communities to mitigate their impacts on the environment and improve their effectiveness and trading account. There are both large and small windpower plants with over 600 small turbine generators on the network on the isles.
They needed a way to improve their power supplies and replaced a new underwater power line with an intelligent powerline. Orkney's was the first power system in the Orkney Archipelago to combine an accumulator with the power of integrating photovoltaic, marine, wind power and hydroelectric. It has been in operation on Orkney for over three years and is the first of its kind in the area.
The Orkney Smartgrid added one of Europe's biggest power storages, a 2MW lithium-ion bank from Mitsubishi Heavy Industries, in 2013. Elsewhere, Gigha Island will launch a vanadium discharge system in 2015, while the Pure Energies Project on Unst in Shetland has already implemented the production and retention of hydro.
Managing it is an important part of the sustainable island concept. The perhaps most important advantage of the sustainable island concept is that it minimizes dependence on crude gas prices and changes in crude gas prices. Further clear advantages are the more effective managment of our drinking and waste waters and the improvement of our climate and the emergence of a low-carbon world.
The Danish island of Samsø has been converted to zero carbons | Guardian Sustainable Business
If you have doubts about the possibilities of renewables, you don't need to look any further than the island of Samsø in Denmark. This 4,000-inhabitant island in the Kattegat Sea has been energy-positive for a ten-year period and produces more power from land and sea than it used. This year, the island won a contest organised by the Denmark Department of the Enviroment and the Department of Electricity, which was looking for a model municipality - a contest that could demonstrate that the newly declared Kyoto goal of reducing GHGs by 21% was actually attainable.
Competition did not provide the means to finance the transformation of our energies. However, she paid the wage of a man who was charged with implementing the ten-year renewable energies management scheme on the island. This was Søren Hermansen, a Samsø-born grower who became an environment schoolteacher. Over the past two years Hermansen has transformed his own practical approach, his own country town into a verdant power station and shown municipalities around the globe that they too can make the switch.
"Hermansen, who runs the Samsø Energie- und Umweltorganisation and is managing director of the Samsø Energieakademie, says: "It wasn't from one day to the next. Currently he is in Australia to address the Community Power Congress in Melbourne. Until 2000, 11 one-megawatt power plants provided the 22 island towns with enough power to make them self-sufficient.
In 2002, another 10 off-shore windpower plants were built, producing 23 MW of power to compensate for the emission levels from automobiles, busses, tractors as well as the ferry that link the island to the north. Meanwhile, three fourths of the island's homes are supplied with heat and warm running through kilometre-long pipelines from central bio-mass fired boiler plants that run on local hay.
The inhabitants of Saamsø now have a CO2 emissions of 12 tons per capita per year in comparison to a Dane mean of 6.2 tons and 17 tons in Australia in 2015. The participation of the EU was indispensable for the implementation of the Zero Carbon Mechanism Roadmap, says Hermansen. For example, the windpower plants are in the possession of a mixture of privately held companies, groups of investors, the city administration and regional co-operatives.
"Hermansen says, "We are living in a small society, so it is very important that we divide the property. In the case of on-shore windpower plants, the concept was that you could register as a co-investor if you could see the plant from your sill. Hermansen says this has suppressed any boiling dissatisfaction (e.g. about the appearance of the turbines) that could have occurred if only a few in the municipality had benefited from it.
Natives subscribed on to the tune of AU $2. 5m, enough to buy two turbos fully, with the remaining nine bought by singles. It also owns two cooperative off-shore wind farms, and the five of them are municipal revenues that the municipal authorities can re-invest in current sustainable development schemes. These enthusiasms result both from the wish to be a self-sufficient, flourishing peasant society and from the wish to reduce carbon use.
With the continuous buzz of infrastructural developments, the village has had a stimulating effect, offering much needed employment and a continuous flow of eco-visitors who want to know about the island's success. It is the island's view to be free of fossile fuels by 2030. It was two years ago that the local authority changed its diesel-powered boat to a gas-powered one, and there are long-term plans to upgrade the boat to run on biofuels from the island and recharged battery power.
It' s simple to imagine Samsø's power transformation as a unique case, powered by the courage and resolve of the rugged Scandinavians who live on a wind-swept former venture of the Vikings. "Samsø should not be seen as'the' model,' he says. For example, much bigger municipalities with ten thousand inhabitants are also switching to renewables.
"Samso is only a mirror image of what is going on in Denmark in general. There is no excitement at the nationals' levels in Canberra, for example in the city of Armidale in New South Wales or on Kangaroo Island in South Australia. "There is a separation between the countryside and the Swiss Confederation," he says.
According to his own experiences, it is indispensable to provide assistance at German power generation companies with adequate feed-in compensation for renewables and public sector incentive to introduce new technology. "It' s very important that the German authorities give it the right framework," he says. - The Community Congress will take place in Melbourne on 27 and 28 February.
