With the spotlight shining on clean energy, the stage has been set for the U.S. to rid itself of a harmful addiction to foreign oil. The stars are aligned and the cards have been dealt. Soon we’ll have kicked the dirty habit, right?

Sarah Palin seems to think so. Perhaps you’ll remember her proposal to tap the natural gas supply found under the pristine Alaskan wilderness. As Governor of Alaska she “fought to bring about the largest private-sector infrastructure project in North American history . . . a nearly $40 billion natural gas pipeline to help lead America to energy independence.”

Tar sand, a source of non-conventional oil, consists of bitumen, a sticky, tar-like form of petroleum which is so thick and heavy that it must be heated or diluted before it will flow. Harvesting tar sand requires huge amounts of energy and water.

In addition to heavy water use, extraction of Alberta’s Athabasca oil sands also involves clear-cutting of the Boreal Forest, formation of toxic “tailings” lakes, habitat destruction of iconic species such as the woodland caribou, and up to five times higher greenhouse gas emissions than conventional oil extraction. All of these factors lead Canada’s Environmental Defence to label tar sand development “the most destructive project on Earth.”

People in Montana have been noticing some big rigs on their highways, really big rigs.

Special trucks the size of a football field are carrying equipment cargo in “superloads” to the Canadian Tar Sands for oil extraction.

The Billings Gazette reports on the massive size of the trucks:

How big? One load that is coming up from the port of Houston and began its passage through Montana on Wednesday is 20 feet wide, slightly more than 20 feet tall and 290 feet long. It has 90 tires on 24 axles and weighs 917,000 pounds - so heavy that two trucks are attached to the rear to help push it along.

In his recent book Tar Sands: Diry Oil and the Future of a Continent, Nikiforuk lands a knockout blow on the kissers of the oil industry, oil-friendly bureaucrats, and petrol-guzzling North Americans. It is obvious that this Canadian is sick and tired of watching his own beloved habitat mutate from a pristine Northern ecosystem to a veritable toxic wasteland.

That said, Nikiforuk is clearly perturbed (another “p” word springs to mind…but this is a family-friendly blog). His book combines intensive research with a lively, caustic writing style…sort of enlightened invective. This makes for an astonishingly entertaining read that raises your hackles while raising your awareness about a seriously dangerous issue.

85 year old Liz Moore is nobody’s fool. The minute she laid eyes on Syncrude’s Canadian Oil Sands operation in Alberta, Canada, she knew some terrible things were happening to the ecology of that area. While touring the company’s site, she took pictures of land not reclaimed, a few snapshots in the visitors center, and came home to Colorado bound to tell a story. She set up a website, The Oil (Tar) Sands of Alberta The Canada/U.S. Connection, and published her pictures along with some interesting facts about the operation.

Almost immediately, Syncrude’s legal staff wrote her and demanded she remove the pictures she had taken. Shortly thereafter, the company’s publishing firm did the same, as did the Alberta provincial government concerning pictures of the Oil Sands Discovery Center which they helped fund.

Liz also maintains another website: Energy Smart

Here is her story….

Now if the natural gas and land depletion aren’t enough to get you thinking; the water consumption is heinous. It takes two to four barrels of water to produce one barrel of bitumen (which is what they are really after). The used tailings are then stored, unusable, in tailings lakes, which have potential negative effects on the health of the environment and the population surrounding the contaminated area.

Oil Sands Facts

Climate Change
· Alberta’s greenhouse gas regulation does not require real reductions in emissions from oil sands operations.
· Oil sands production is much more greenhouse gas–intensive than conventional oil production.
· Oil sands are the fastest-growing source of greenhouse gas emissions in Canada.
· Continued increases in greenhouse gas emissions show that Canada’s commitment to address climate change falls far short of what’s needed.
· Large-scale carbon capture and storage for oil sands emissions is currently a distant and uncertain prospect.
· Companies are allowed to switch to burning dirtier fuels as a source of energy for oil sands extraction — further increasing greenhouse gas emissions from the oil sands.

Water Impacts
· Oil sands mining uses two to four barrels of water for every barrel of bitumen produced.
· Oil sands companies are not required to stop withdrawing water from the Athabasca River, even if flows are so low that fisheries and habitats are at serious risk.
· Capping toxic tailings waste in end pit lakes with water is an unproven and risky concept.
· For over 40 years, oil sands mining companies voluntarily managed tailings on their own, in the absence of concrete government regulations.
· Tailings lakes seep toxic waste. It is uncertain exactly what is seeping, how much is seeping and what ecosystem components are affected.
· Tailings lakes house compounds known to be acutely toxic to aquatic organisms.
· Reclamation of tailings lakes has not yet been demonstrated.

Boreal Forest Impacts
· Alberta’s oil sands underlie one-fifth of the province, and development is already planned for more than 79,000 square kilometers.
· The Athabasca Boreal Forest will not be restored to its native state following mine closure.
· Oil sands mining reclamation standards are weak and lack transparency; only one square kilometer of land has been certified as reclaimed to date.
· The security bonds that are supposed to protect Canadians from costly environmental liabilities may be inadequate.

Perhaps Alaska’s natural gas store will help America achieve oil independence. But it is going to take strong regulations to stop the spread of “the most destructive project on earth.”
