A report on phasing out nuclear power in Sweden

It may make politicians and activists feel empowered and righteous, but it has negative aspects that don’t seem to get the same level of attention as the “feel good” rhetoric does:

Nuclear power faces an uncertain future in Sweden. Major political parties, including the Green party of the coalition-government have recently strongly advocated for a policy to decommission the Swedish nuclear fleet prematurely. Here we examine the environmental, health and (to a lesser extent) economic impacts of implementing such a plan. The process has already been started through the early shutdown of the Barsebäck plant. We estimate that the political decision to shut down Barsebäck has resulted in ~2400 avoidable energy-production-related deaths and an increase in global CO2 emissions of 95 million tonnes to date (October 2014). The Swedish reactor fleet as a whole has reached just past its halfway point of production, and has a remaining potential production of up to 2100 TWh. The reactors have the potential of preventing 1.9–2.1 gigatonnes of future CO2-emissions if allowed to operate their full lifespans. The potential for future prevention of energy-related-deaths is 50,000–60,000. We estimate an 800 billion SEK (120 billion USD) lower-bound estimate for the lost tax revenue from an early phase-out policy. In sum, the evidence shows that implementing a ‘nuclear-free’ policy for Sweden (or countries in a similar situation) would constitute a highly retrograde step for climate, health and economic protection.

How Buildings Learn – Stewart Brand – 2 of 6 – “The Low Road”

Published on 10 Jun 2012

This six-part, three-hour, BBC TV series aired in 1997. I presented and co-wrote the series; it was directed by James Muncie, with music by Brian Eno.

The series was based on my 1994 book, HOW BUILDINGS LEARN: What Happens After They’re Built. The book is still selling well and is used as a text in some college courses. Most of the 27 reviews on Amazon treat it as a book about system and software design, which tells me that architects are not as alert as computer people. But I knew that; that’s part of why I wrote the book.

Anybody is welcome to use anything from this series in any way they like. Please don’t bug me with requests for permission. Hack away. Do credit the BBC, who put considerable time and talent into the project.

Historic note: this was one of the first television productions made entirely in digital — shot digital, edited digital. The project wound up with not enough money, so digital was the workaround. The camera was so small that we seldom had to ask permission to shoot; everybody thought we were tourists. No film or sound crew. Everything technical on site was done by editors, writers, directors. That’s why the sound is a little sketchy, but there’s also some direct perception in the filming that is unusual.

The state of the Royal Canadian Navy

It’s worse than you might think:

HMCS Athabaskan

HMCS Athabaskan

Maclean's maritime chartThis October, NATO is launching Trident Juncture, its largest and most ambitious military exercise in a decade. The massive land, sea and air exercise will be held in the Mediterranean and will include 36,000 troops from 30 nations. Its goal will be to help the fictitious country of Sorotan, “a non-NATO member torn by internal strife and facing an armed threat from an opportunistic neighbour.” Not surprisingly, this is widely seen as an explicit response to Moscow’s increasingly belligerent pressure on the alliances’ eastern borders. The Canadian government, an outspoken critic of Russian President Vladimir Putin and the invasion of Ukraine, had planned to send its flagship destroyer, HMCS Athabaskan, as “a strong signal to the Russians,” whose ships and aircraft have also been bumping up against Canada’s territorial claims in the Arctic.

But, last week, it was reported by the Ottawa Citizen that the 43-year-old Athabaskan was no longer seaworthy and is being sent back to Halifax for extensive repairs. Athabaskan is a fitting symbol of the overall state of the Navy: Its engines require an overhaul, the hull is cracked, the decks need replacing, and the weapon systems are questionable. Even Rear Admiral John Newton, commander of Maritime Forces Atlantic, describes his flagship as worn and tired.

In February, during a storm off the East Coast, Athabaskan was damaged and a number of engines failed. After that, the Royal Canadian Navy (RCN) decided it was no longer capable of weathering the heavy seas of the North Atlantic, so it was sent south for calmer seas. Nonetheless, its engines broke down in Florida, then again in placid Caribbean waters.

“It was garbage. Everything was always breaking,” says Jason Brown, who served as an electrician and technician on Athabaskan for seven years, ending in 2010. “We did 150 to 300 corrective maintenances a month.” Although Brown praises the ship’s crew, he often spent 20-hour days trying to fix equipment. “The two main engines didn’t like to play nice together. It was 4½ years before that issue got fixed.”

[…]

Compared to its allies, the Canadian Navy is now only one-third the size it should be, given our GDP, and can only play smaller and smaller roles. Stanley Weeks of the U.S. Naval War College, a former U.S. admiral who follows NATO closely, is dismayed at the decline of the RCN. “[Canadian politicians] need more seriousness. Canada is an inherently maritime nation, dependent on overseas markets, especially in Asia Pacific, and, therefore, it has to be a contributing stakeholder, militarily and diplomatically.” He believes American military leaders in the Pentagon have not yet grasped the serious implications of losing the Canadian destroyers. Regardless, “Canadians should worry more about this than Washington.”

QotD: The Anglo-German Naval Race

Filed under: Africa, Britain, Europe, Germany, Quotations — Tags: , , — Nicholas @ 01:00

Germany’s decision to embark on an ambitious naval programme has occupied a commanding position in the literature on the origins of the First World War. Viewed with hindsight, it might appear to foreshadow, or even perhaps to explain, the conflict that broke out in 1914. Wasn’t the decision to challenge British naval hegemony a needless provocation that permanently soured relations between the two states and deepened the polarization of the European system?

There are many criticisms one can make of German naval strategy, the most serious being that it was not embedded in a broader policy concept, beyond the quest for a free hand in world affairs. But the new naval programme was neither an outrageous nor an unwarranted move. The Germans had ample reason to believe that they would not be taken seriously unless they acquired a credible naval weapon. It should not be forgotten that the British were accustomed to using a rather masterful tone in their communications with the Germans. In March 1897, for example, a meeting took place between the assistant under-secretary at the British Foreign Office, Sir Francis Bertie, known as “the Bull” for his aggressive manner, and the chargé d’affaires and acting German ambassador in London, Baron Hermann von Eckardstein. In the course of their discussion, Eckardstein, a notorious Anglophile who dressed in the manner of Edward VII and loved to be seen about the London clubs, touched on the question of German interests in southern Africa. Bertie’s response came as a shock. Should the Germans lay so much as a finger on the Transvaal, Bertie declared, the British government would not stop at any step, “even the ultimate” (an unmistakable reference to war), to “repel any German intervention”. “Should it come to a war with Germany,” he went on, “the entire English nation would be behind it, and a blockade of Hamburg and Bremen and the annihilation of German commerce on the high seas would be child’s play for the English fleet.”
