“My humble plan was to become a hero of the environmental movement. I was going to go up to the Canadian Arctic, I was going to write this mournful elegy for the polar bears, at which point I’d be hailed as the next coming of John Muir and borne aloft on the shoulders of my environmental compatriots …
“So when I got up there, I started realizing polar bears were not in as bad a shape as the conventional wisdom had led me to believe, which was actually very heartening, but didn’t fit well with the book I’d been planning to write.”
All those in favour of keeping away from power those with a violent, intolerant, and dogmatic view on how humans should collectively and individually behave… don’t raise your hand.
UPDATE: The producers of the film have responded to the predictable response,
Last week, 10:10 made available a short film. Following the initial reaction to the film we removed it from our website and issued an apology on Friday 2 October.
Subsequently there has been negative comment about the film, particularly on blogs, and concern from others working hard to build support for action on climate change. We are very sorry if this has distracted from their efforts.
We are also sorry to our corporate sponsors, delivery partners and board members, who have been implicated in this situation despite having no involvement in the film’s production or release.
We will learn from this mistake. Today I have written to supporters and stakeholders explaining that we will review processes and procedures to make sure it cannot happen again. Responsibility for this process is being taken by the 10:10 board.
The media coverage of the film was not the kind of publicity we wanted for 10:10, nor for the wider movement to reduce carbon emissions.
If people have been in touch with us personally about the film, we will be replying to individual emails over the next few days. Meanwhile our thanks go out to all those who support 10:10 and who work to combat the threat of climate change.
More than 300 sea birds, mostly brown pelicans and northern gannets, have been found dead along the U.S. Gulf Coast during the first five weeks of BP’s huge oil spill off Louisiana, wildlife officials reported Monday.
While generating megawatts of electricity, windmills on the Tug Hill Plateau in northern New York are also killing hundreds of bats and birds, according to a recent study.
The consultants’ report for PPM Energy and Horizon Energy identified 123 birds, mostly night migrants, and 326 bats found dead over the course of five months last year beneath 50 wind turbines on the plateau between Lake Ontario and the western Adirondacks.
Those poor birds and bats, done in by some windmills. The article describes 123 birds and 326 bats killed by 50 windmills over 5 months. While the other article explains that about 300 birds killed. This by about 37 million gallons of oil over 5 weeks.
The wind-watch article also mentions that those 50 turbines produce 900,000 megawatt hours per year.
50 turbines produce 900,000 MWh per year 4.35 weeks/month * 5 months = 21.75 weeks
21.75 weeks / 52 weeks/year = 0.42 years
0.42 years * 900,000 MWh/year = 376442 MWh produced by windmills over 5 month period
376442 MWh / 123 birds = 3061 MWh per bird killed
Oil vs. Wind
209667 MWh per bird killed (oil) / 3061 MWh per bird killed (wind) ~= 68
What does this mean?
In terms of environmental impact measured by one factor (birds killed), windmills are about 68x more efficient at killing birds per unit energy derived. To garner the same amount of energy needed from wind than from oil, we’d have to operate the windmills 68x longer or increase the number of windmills by 68x in order to get the same amount of energy. This means that about 68x more birds will die if we wanted to match the energy we’d get from oil. This would result in 68 * 123 birds = 8425 birds dead compared to the 300 dead from the oil spill for the same amount of energy derived.
There is, of course, one major flaw in the calculation above (besides my wanton disregard for sig figs). We’ve only considered oil spilled in the gulf. Alas, the vast majority (ie. 99.9999%) of oil isn’t spilled. When oil isn’t spilled, its efficiency in killing birds goes way down. Further, the wind energy we consider above is the norm not the exception; this is the rate of bird death during normal operation of wind turbines.
Clearly, when considering the environmental impact of oil by showing dead oil slicked birds on cable news, oil actually isn’t comparatively bad. In fact, it is a less efficient killer of birds per unit energy derived.
And in Canadian politics, the NDP crows about windmills:
