From an editorial in the La Crosse Tribune:

. . . the pattern repeats itself. When the price of gas gets high enough, all we get are theatrics by Congress to parade the big oil executives in front of hearings. There are special investigations, studies, commissions and plenty of threats and promises, but nothing ever changes.

The oil companies do have us over our own barrel. Take away tax breaks and incentives, and there will be less oil and it will cost more, they argue. And that will cost jobs. And our profits of $36 billion in the first quarter alone — that’s the result of international demand for oil, they say. After all, we’re just providing a needed product for the American economy.

We can’t drill our way out of the fact that we simply consume more oil than we produce. And yet we allow oil to be traded as a commodity where a few speculators get rich while the rest of us hold our breath as the meter on the pumps spins faster and faster.

It’s easy to get mad at the oil companies, whose pomposity and arrogance is an insult to the millions of Americans who struggle to even fill up their tanks. The CEO of ConocoPhillips called repealing the $4.4 billion tax breaks for the biggest oil companies “un-American.”

What’s un-American is that we are still addicted to oil.

Energy policy murky year after oil spill

From an editorial in the La Crosse Tribune:

A year ago Wednesday, the Deepwater Horizon oil rig exploded in the Gulf of Mexico, killing 11 men and spewing 172 million gallons of oil in the ocean.

While we remember images of spewing oil and blackened beaches, nature has shown her remarkable resiliency, despite man’s best attempts at despoiling her.

A report by more than three dozen scientists grade the Gulf’s health as a 68 on a 100-point scale, which is slightly below the grade of 71 they gave the Gulf prior to the spill. While beaches are open as tourism returns to normal, there are still long-term environmental concerns such as hundreds of young dolphins dying and dead spots on the sea floor.

Jane Lubchenco, head of the National Oceanic and Atmospheric Administration, told The Associated Press that the Gulf is “much better than people feared, but the jury is out about what the end result will be. It’s premature that things are good.”

It also will be a while before there are tougher environmental and safety rules regulating the offshore drilling industry. The New York Times published a story Monday that said the Bureau of Ocean Energy Management has much work to do before more rigid rules can be put into place.

There’s certainly plenty of pressure from the oil and gas industry to resume deep-water drilling. A moratorium on new deep-water drilling was lifted in October, and the Interior Department has approved 10 permits and 15 others are pending, the Times said. The House of Representatives has three bills pending that would speed up permit approval and open new areas for drilling off the Atlantic and Pacific coasts as well as easing environmental rules off the Alaska shores.

Our country has an insatiable need for oil but fails to have a comprehensive federal energy policy to wean our dependence on fossil fuel.

From Canada to the Coulee Region: Where our gas comes from

From an article by Richard Mial in the La Crosse Tribune:

On a map of northern Canada, Fort McMurray marks where the highway ends. But it’s the starting point for much of the fuel that runs vehicles in the Coulee Region.

The sands of north Alberta — not the Middle East — provide most of the petroleum that becomes gasoline sold in the La Crosse area.

A pipeline channels that Canadian crude to the Flint Hills Resources Pine Bend Refinery in Rosemount, Minn.

La Crosse-based Kwik Trip is among its primary customers. A fleet of 110 tanker trucks ferries gasoline and diesel fuel 24 hours a day from the refinery to the company’s 363 convenience stores in Wisconsin, Minnesota and Iowa.

The Tribune traced petroleum’s path from the forests of Canada to the pumps.

It’s a route that keeps the region from relying on crude oil from overseas. But it also has raised questions about the environmental costs, both to Canada and Wisconsin.

Oil sands
Alberta’s oil sands region yields about half of the petroleum converted into local gasoline. Production averages about 1.5 million barrels a day, and that’s expected to go up to 1.8 million by 2012, according to estimates by the Canadian Association of Petroleum Producers.

The mixture of sand and thick, tar-like bitumen is mined from the earth with huge shovels, many of them Wisconsin-made.

Large amounts of water are used to separate the oil from the sand — about two to three gallons of water for every barrel of oil, said Don Thompson, president of the Oil Sands Developers Group. Natural gas-fired power plants provide the electricity needed for the energy-intensive process.

Large-scale oil sands mining in the Fort McMurray area dates back to the late 1960s through the Great Canadian Oil Sands, now known as Suncor Energy Inc., said Thompson, a former oil company executive who now lives in Calgary.

Another company, Syncrude, began mining the oil sands in the late 1970s, Thompson said in a telephone interview.

But oil sand production remained limited until the price of a barrel of oil rose enough to justify the expense of oil sand mining, and the quality of technology improved, Thompson said.

Now, about 208 square miles of northern Alberta have been cleared for mines, tailing ponds and “upgraders,” plants that provide some refining before the oil is sent by pipeline to the United States and elsewhere.

A story in National Geographic Magazine includes dramatic photos of tar sands mining.

Geologists: Energy's future in for big change

From an article by Joe Knight in the Eau Claire Leader-Telegram:

"This is the age of oil, but the age of oil is about to end," said Lori Snyder of UW-Eau Claire's geology department.

In 1950, the U.S. did not import any oil. Today, we still like our cars, and we have to import 60 percent of the oil we use to support our driving habit, she said.

Vehicles may have gotten a smaller and more fuel efficient since the 1950s, but our appetite for energy - the majority of it coming from fossil fuels - is huge. Today the average American uses three times the amount of energy we used in 1950, Snyder said.

Snyder and J. Brian Mahoney, also of the geology department, discussed the future of fossil fuels and energy Tuesday night for an "Ask A Scientist" program at UW-Eau Claire.

An audience of mixed ages attended, and many asked questions of the scientists, but the answers they received painted a less-than-reassuring picture of our energy future.

Fossil fuel basically is solar energy trapped by plants and bugs - sometimes millions of years ago - that never completely decomposed. We have extracted the fuels and used it to power our cars, heat our homes and generate our electricity, but supplies are becoming scarce, the geologists said.

Oil supplies in the U.S. peaked in the 1970s, Mahoney said. World supplies of oil that is readily accessible are peaking now, he said.

There are some alternative sources of oil, such as sand tars in Alberta, Canada, which are being mined, but they require a substantial amount of energy to extract and are costly to the environment, Mahoney said.

We still have an abundance of coal in the U.S. - enough to meet our electrical needs for 200 to 250 years, Snyder said. Unfortunately, coal is the dirtiest fossil fuel for emissions. We're already altering the composition of the atmosphere, and continuing at the current rate or increasing emissions brings about more questions about climate change and what life on Earth might be like in 100 years, Mahoney said.

"It's taking us to a place we don't really understand," he said.

Revitalizing Ourselves Through Renewable Energy



From a presentation by RENEW's Michael Vickerman (above) at the Energy Fair of the Midwest Renewable Energy Association:

Energy Policy Must Recognize Energy Realities
+ Supplies of liquid fuels peaked in 2008
+ Capital is disappearing before our very eyes
+ Energy and food are the original currencies
+ The shift from stores to flows is inevitable
+ Current economy is highly energy-intensive
+ Energy return on energy invested (EROEI) must inform decision-making
+ We can’t afford to prop up existing energy sinks or engage in wealth-draining military adventures

Three paths to choose
+ Business as usual
+ Clean green technology
+ Curtailment and community
