Summer of Resistance in Iceland – an overview

This year, Iceland saw its third Summer of direct action against heavy industry and large dams. In a much-disputed master plan, all the glacial rivers and geothermal potential of Europe’s largest wilderness would be harnessed for aluminum production (see EF!J May-June 2006). Activists from around the world have gathered to protect Europe’s largest remaining wilderness and oppose aluminum corporations.

‘Aluminium Tyrants’ – The Ecologist

IcelandFTcartoonsml.jpgBy Jaap Krater, Miriam Rose and Mark Anslow, The Ecologist, October 2007.

The gates of a geothermal power station are not where you would expect to find environmental activists. But the morning of 26th July 2007 saw the access road to Hellisheidi power station in Hengill, South-West Iceland, blockaded by a group of protestors from the campaign group ‘Saving Iceland’. After a brief demonstration, nine activists were arrested and several now face legal action.

Geothermal power in Iceland is big business. Just five plants generate 3 TWh a year – more than the annual output from all the UK’s wind turbines combined (Orkustofnun 2005; BERR 2006). Geothermal power also provides at least 85 per cent of Iceland’s homes with heat and hot water. This abundance of cheap, largely CO2-free energy has attracted energy-hungry industries to the country like sharks to a carcass. Of these, by far the most energy intensive is the aluminium industry (Krater 2007; Saving Iceland 2007).

Hydropower Disaster for Global Warming by Jaap Krater, Trouw daily

Trouw (daily), Netherlands, 21 January 2007

Large dams have dramatic consequences. Ecosystems are destroyed and numerous people are made homeless, often without adequate resettlement. But it is yet little known that large-scale hydro-electricity is a major contributor to global warming. The reservoirs could, despite their clean image, be even more devastating for our climate than fossil fuel plants.


narmada mapA few years ago, I spent a month in the valley of the Narmada River, to support tribal activists who have been resisting the Sardar Sarovar dam in central India for decades. These indigenous inhabitants, or adivasis, are desperate. In their struggle, inspired by Gandhi, they attempt to drown themselves when their villages are flooded. Death seems preferable to being forced to move from their valley to tin houses on infertile, barren soil. If they’re lucky, they can live on land that nobody else wants, the only available in the densely populated India. This forced resettlement, made necessary by ´progress´, is not unsimilar to what befell American Indians or the Aborigines in Australia. The consequences of mega hydro: cultures die and alcoholism, depression and violence remains. Read More

Saving Iceland Blockades Rio Tinto-Alcan Smelter in Hafnarfjordur

Landsvirkjun Involved in Coal & Nuclear Powered RioTinto-Alcan Smelter in Africa
Hafnafjordur_blockade_240707_5HAFNAFJORDUR – Saving Iceland has closed access to RioTinto’s Straumsvik smelter in South-West Iceland. About 20 protestors have locked their arms in metal tubes and climbed onto cranes on the smelter site. Saving Iceland opposes plans for a new RioTinto-Alcan smelter in Keilisnes or Thorlakshöfn, expansion of the existing smelter, and a new coal and nuclear powered smelter in South Africa.

“Protests against Alcan have been successful. Of course the people of Hafnafjordur have stopped the expansion of Straumsvik and recently, in Kaskipur, Northeast India, Alcan had to give up it’s participation in a bauxite mine because of protests against their human rights violations and environmental devestation. Alcan has been accused of cultural genocide in Kashipur, 1 because mining and dams have already displaced 150.000 mainly tribal people there 2. Norsk Hydro left the project when police tortured and opened fire on protestors, and then Alcan moved in,” says Saving Iceland’s Jaap Krater.

The reaction of Ca derived from silicate weathering with CO2 in the world’s oceans to form carbonate minerals is a critical step in long-term climate moderation. Ca is delivered to the oceans primarily via rivers, where it is transported either as dissolved species or within suspended material. The relative importance for climate moderation of riverine dissolved Ca vs. suspended Ca transport stems from the total Ca flux and its climate dependence. Data in the literature suggest that, within uncertainty, global riverine dissolved Ca flux is equal to suspended material Ca flux. To determine how these fluxes depend on temperature and rainfall, a 40 yr field study was performed on 4 catchments in northeastern Iceland: Jökulsá á Fjöllum at Grímsstadir, Jökulsá á Dal at Brú, Jökulsá á Dal at Hjardarhagi, and Jökulsá í Fljótsdal at Hóll. Suspended material Ca flux depends more on seasonal and annual temperatures and rainfall variation than does dissolved Ca flux in all four catchments. For example, the average difference between the annual maximum and minimum daily suspended Ca flux for the Jökulsá á Dal at Brú is four orders of magnitude, whereas the difference for dissolved Ca flux is only approximately one order of magnitude. Similarly, the annual dissolved Ca flux for this river varies by a factor of 2.6, whereas its annual suspended Ca flux varies by a factor of 7.1. Because suspended material Ca flux is more dependent on climate, it provides a stronger negative feedback for stabilizing Earth’s temperature through the greenhouse effect. Read More

Hydroelectric Power’s Dirty Secret Revealed – New Scientist

Hydroelectric dams produce significant amounts of CO2 and methane – some produce more greenhouse gases than fossil fuel power plants.

Duncan Graham-Rowe, New Scientist, 26-2-2005, issue 2488

Contrary to popular belief, hydroelectric power can seriously damage the climate. Proposed changes to the way countries’ climate budgets are calculated aim to take greenhouse gas emissions from hydropower reservoirs into account, but some experts worry that they will not go far enough.

The green image of hydro power as a benign alternative to fossil fuels is false, says Éric Duchemin, a consultant for the Intergovernmental Panel on Climate Change (IPCC). “Everyone thinks hydro is very clean, but this is not the case,” he says.

Hydroelectric dams produce significant amounts of carbon dioxide and methane, and in some cases produce more of these greenhouse gases than power plants running on fossil fuels. Carbon emissions vary from dam to dam, says Philip Fearnside from Brazil’s National Institute for Research in the Amazon in Manaus. “But we do know that there are enough emissions to worry about.”

“Reservoirs convert carbon dioxide in the atmosphere into methane, which has 21 times the warming effect” Read More
