Extracting oil from oil shale takes a lot of water. Most of the oil shale in the U.S. is in areas where there’s not a lot of water. Conrad Wilson reports, one big oil company seems to be walking away from oil shale for that reason. But not everyone thinks that’s the case.

In the Western US, some energy companies are betting big on oil shale. That’s a process of basically heating up a shale rock into a liquid that’s eventually refined into oil. But the global recession and the threat of climate change might be giving those companies second thoughts. Add to that a increasingly limited water supply, and oil shale looks like a risky investment.

The process of creating oil shale is energy intensive and uses a lot of water. That’s a problem in the arid West. As the population grows, the value of water is increasing.

Royal Dutch Shell has the most invested in developing an oil shale technology that works. So earlier this year when the company announced it was pulling away from water rights, it sent shock waves through the industry.

“I read that decision as Shell’s acknowledgment that oil shale is a long way off and that this was a really controversial filing and that in a sense it’s not worth it.”

That’s Claire Bastable of the Western Energy Project. It’s an environmental group that keeps on eye on energy issues in the West. Shell had been pursuing water rights on the Yampa River, in the Northwest portion Colorado.

“Shell’s decision was a big deal. We’re talking about 15 billion gallons of water. … It would have basically taken the Yampa River, which is one of the the last free flowing rivers in the West and diverted a huge proportion of it to Shell for potential oil shale development.”

Bastable says the 15 billion gallons Shell was seeking is about three times the amount the city of Boulder, Colorado uses in a year.

But, Shell knows a lot of oil can be extracted from the oil shale. It’s estimated that there are 800 billion barrels of usable oil in the shale – in Wyoming, Colorado and Utah.

Dr. Jeremy Boak researches oil shale development at the Colorado School of Mines. He says Shell could be simply postponing extracting that oil. Boak believes oil shale has a future, but it’s still decades away.

“With all of the comments they’ve made about what the time scale for oil shale, Shell has been pretty comfortable that this is going to take time.”

Shell says that even though it’s no longer pursing water rights on the Yampa River right now, it’s in no way backing off its larger ambitions for oil shale.

The company wouldn’t provide someone to comment for this story, but in a statement the company said:

The “ultimate goal is to create a commercial oil shale recovery operation that is economically viable, environmentally responsible and socially sustainable.”

That statement adds timing depends on government regulation and the market. The company could be waiting to see what the government does about climate change and how that affects fossil fuel costs. Shell could also be waiting for oil prices go up before deciding whether oil shale worth the effort.

Eric Kuhn heads up water management for the Colorado River District. He monitors much of the state’s water West of the Continental Divide. Kuhn says there’s probably enough water for oil shale development right now, but it’s hard to say for how long.

“I don’t think they’re dropping the filing changes anything. I think those companies are dedicated to and still have a plan to develop the oil shale resource if they can find a technology that is economically productive or if they can produce the oil shale at a competitive price, I think they will do it.”

Environmentalists in the region hope they won’t. They say Shell’s decision not to pursue the water right now should be a signal to others… oil shale just might not be worth the effort.

New polling data show drilling for oil and mining for coal is more important to Americans than protecting the environment. Lester Graham reports:

For the first time since Gallup started asking the question nine years ago, the pollsters found Americans put a higher priority on energy production than environmental protection. Frank Newport is the Editor in Chief for Gallup. He says 50-percent of those polled put energy production as a higher priority while 43-percent put environmental protection as a higher priority.

“In other words, I think some Americans are saying we don’t have the luxury at the moment of worrying about the environment in the bad economic times.”

Attitudes seem to be affected by the down economy, more than anything else. Even when gasoline was four-dollars a gallon, most of the people put the environment ahead of energy production.

Acidic Oceans Dissolving Shellfish Industry

  • Oceanographer Richard Feely says the shellfish industry is suffering in part because the more acidic seawater encourages the growth of a type of bacterium that kills oyster larvae.(Photo courtesy of the NOAA)

When carbon dioxide is released into the atmosphere, about a third of it absorbs into the ocean. That creates carbonic acid—the stuff in soda pop that gives it that zing.

That means seawater is becoming more acidic.

Scientists say this ocean acidification is starting to cause big problems for marine life. And Ann Dornfeld reports that could affect your dinner plans.

When carbon dioxide is released into the atmosphere, about a third of it absorbs into the ocean. That creates carbonic acid—the stuff in soda pop that gives it that zing.

That means seawater is becoming more acidic.

Scientists say this ocean acidification is starting to cause big problems for marine life. And Ann Dornfeld reports that could affect your dinner plans.

Taylor Shellfish Farms has been growing oysters for more than a
century. And shucking them, one by one, by hand.

“An old profession. Y’know, they’ve tried for years to
find a way to mechanize it. There’s no way around it. Every oyster is
so unique in its size and shape.”

Bill Dewey is a spokesman for Taylor. The company is based in
Washington state. It’s one of the nation’s main producers of farmed
shellfish. Dewey says if you order oyster shooters in Chicago, or just
about anywhere else, there’s a good chance they came from Taylor.

But in the past couple of years, the company has had a hard time
producing juvenile oysters – called “seed.”

“Last year our oyster larvae production was off about 60
percent. This year it was off almost 80 percent. It’s a huge impact to
our company and to all the people that we sell seed to.”

Shellfish growers throughout the Pacific Northwest are having similar
problems with other kinds of oysters, and mussels, too. They suspect a
lot of it has to do with ocean acidification.

Richard Feely is a chemical oceanographer with the National Oceanic
and Atmospheric Administration. He says when the pH of seawater drops
too low, it can hurt marine life.

“What we know for sure is that those organisms that
produce calcium carbonate shells such as lobsters, and clams and
oysters, and coral skeletons, they generally tend to decrease their
rate of formation of their skeletons.”

Feely says it looks like acidified waters are affecting oysters
because their larvae build shells with a type of calcium carbonate,
called aragonite, which dissolves more easily in corrosive water.

The more acidic seawater also encourages the growth of a type of
bacterium that kills oyster larvae.

Feely says the changes in the ocean’s pH are becoming serious. He
recently co-published a study on the results of a 2006 research cruise
between Hawaii and Alaska. It was identical to a trip the researchers
took in 1991. They found that in just 15 years, the ocean had become
five to six percent more acidic as a result of man-made CO2.

“If you think about it, a change of 5% in 15 years is a
fairly dramatic change. and it’s certainly humbling to see that in my
lifetime I can actually measure these changes on a global scale. These
are very significant changes.”

A couple years ago, Feely gave a talk at a conference of shellfish
growers. He explained the impact ocean acidification could have on
their industry. Bill Dewey with Taylor Shellfish Farms was there.

“All these growers were walking around with all these
really long faces, just very depressed. I mean it was a very eye-opening presentation and something that’s definitely had growers
paying attention since, that this could be a very fundamental problem
that we’re going to be facing for a long time to come.”

Dewey calls shellfish growers the “canary in the coalmine” for ocean
acidification.

Scientists say if humans don’t slow our release of CO2 into the
atmosphere, shellfish may move from restaurant menus into history
books.

Honeybees have been dying by the millions because of colony collapse disorder. But government officials say it’s not just the bees that are in trouble. Lester Graham reports.

Jeffrey Pettis heads up the USDA’s bee lab in Beltsville, Maryland. He says there’s a lot of concern about honey bees because they pollinate crops. But he’s also really concerned about wild native bees, butterflies, bats that pollinate plants in the wild.

“The wild plants that rely on native pollinators can be in trouble as well. So, there’s certainly should be concern for all pollinators in addition to honeybees, which I like to think of as a major agricultural pollinator.”

Pettis says habitat destruction is hitting nature’s wild pollinators hard, but bats are also dying because of white-nose syndrome, a fungus that’s spreading, killing bats by the millions.

Federal Government Invests in Sustainable Planning

  • Getting to work is now the second biggest expense for most Americans, after housing. (Photo courtesy of the Federal Highway Administration)

Planners say people are being forced to spend too much money to get to and from work. The government sees that problem in regions around the country and is ready to spend millions of dollars to plan improvements. Julie Grant reports.

Planners say people are being forced to spend too much money to get to and from work. The government sees that problem in regions around the country and is ready to spend millions of dollars to plan improvements that put jobs and housing closer together… or at least give people more transportation options to get to work. Julie Grant reports.

Dwayne Marsh says for decades, the department of Housing and Urban Development has built housing in one part of a community, while the Department of Transportation invested in another — with no coordination.

“I THINK THAT BECAUSE THE RESPECTIVE AGENCIES WEREN’T IN TIGHT ALLIANCE, THERE OFTEN WOULD BE REGULATIONS THAT WERE AT CROSS PURPOSE.”

That’s one reason why highways often bypass rural communities entirely and split inner-city neighborhoods in two.

Marsh works in a new office within HUD that’s working to integrate housing planning with Department of Transportation, as well as the Environmental Protection Agency.

“NOW WE’RE WORKING REALLY HARD TO ELIMINATE THOSE BARRIERS, SO WHEN COMMUNITIES GET FEDERAL DOLLARS THEY CAN BE USED IN A SYNCHRONOUS WAY.”

The three agencies have 140-million dollars in grants for local governments and regions around the country to do better planning.

And HUD has done something no one can remember it doing before: it’s gone on tour — to Seattle, Denver, Cleveland, and elsewhere. Before HUD starts doling out the planning money, Marsh says they want to hear the vision local communities have for sustainable development.

“YOU KNOW, I’M SNARKY ABOUT THE WHOLE THING ABOUT SUSTAINABILITY.”

Ned Hill is Dean of the college of Urban Affairs at Cleveland State University. He says sustainability means so many different things to different people.

To him, sustainable goes beyond environmental effects.

“AT THE FOUNDATION OF ANY SORT OF SUSTAINABILITY IS HAVE AN ECONOMY THAT’S SUSTAINABLE. AND IN THE OLDER INDUSTRIAL CITIES, OUR FIRST CHALLENGE IS TO RELOAD THE ECONOMY.”

In many of those older cities, as people have moved farther into the suburbs, they’ve started new businesses close to where they live. Hill says that’s why in areas like Cleveland, the central city is no longer the central business district.

Highways have been built to connect the different suburbs – and people are driving all over the place to get to work in those suburbs.

But, getting to work is now the second biggest expense for most Americans, after housing.

Shelley Poticha doesn’t think that’s a sustainable model. She’s director of that new HUD sustainability office.

Poticha says the regions where people have to drive the farthest to get to work –and spend the most to get to work—also have the highest numbers of foreclosed homes.

“THE REGIONS THAT FARED THE BEST WERE THOSE THAT HAD A PATTERN OF LAND USE THAT MADE IT POSSIBLE FOR PEOPLE TO GET TO WORK WITH OUT HAVING TO DRIVE.”

Poticha points to regions like Denver, where they plan a 100 miles of commuter rail, and bus rapid transit lanes, linking the 32 communities surrounding Denver proper. She says Denver wants to use this new federal grant money to design urban villages around those transit stations. So instead of acres of parking lots, there could be a grocery and other retail stores.

The idea is that people won’t have to drive to work and then drive to the store. Instead, they can take mass transit, and get their shopping done and not have to drive all around.

Poticha says that can help reduce pollution and help families to save money.

Dwayne Marsh says the Obama administration is sending a clear message: improving the economy is dependent on transportation options, housing affordability and a cleaner environment:

“AND BECAUSE THE FEDERAL GOVERNMENT PLAYS A ROLE IN ALL OF THOSE ACTIVITIES, WE NEED TO BE FOSTERING INNOVATION COMING FROM LOCAL COMMUNITIES THAT CAN TAKE ON SOME OF OUR TOUGHEST NATIONAL PROBLEMS. AND WE CERTAINLY DON’T WANT TO BE AN IMPEDIMENT TO THAT CREATIVITY.”

Marsh says his HUD office will work with the Transportation Department and the EPA to help – instead of getting in the way – of local areas’ creative solutions.

Oil Prices on the Rise

  • Stephen Schork says the rising prices are based more on investor momentum than anything else, and that there’s plenty of oil on the market.(Photo courtesy of the Federal Highway Administration)

Oil and gasoline prices are going up this summer. Lester Graham reports, it appears the higher prices are not caused by lower supplies.

Transcript

The Energy Information Administration’s new short-term energy outlook says gasoline prices will average about $2.92 this summer– hitting $3.00 or more in some regions. That’s about 50-cents a gallon higher than last summer.

The outlook also predicts oil prices to average $82 a barrel this summer. But, oil already hit $86 a barrel this week.

Stephen Schork with The Schork Report says… the government projections were put together about a week ago… and didn’t really anticipate the investors driving prices up this week.

“So this rally that we are seeing and this upward buy is based more on investor momentum than it is on underlying fundamentals. There’s plenty of oil on the market right now.”

The government says prices should remain relatively stable but rising… although is notes uncertainty over crude oil price forecasts remains high.

Mapping Underground Rivers

The trees and grass that grow up around the sinkhole form a buffer, allowing water to soak into the soil and filtering any pollutants before it reaches the aquifer.(Photo courtesy of Stephanie Hemphill)

Spring in the north is a time of melting snow and running water. It’s the best time of year for people who study underground water flows. Those underground rivers are important, especially where surface water easily drains into bedrock. It can quickly carry pollution long distances. Hydrologists try to map these underground rivers to help protect fragile ecosystems. As Stephanie Hemphill reports, the first step in making these maps is a process called dye tracing.

Spring in the north is a time of melting snow and running water. It’s the best time of year for people who study underground water flows. Those underground rivers are important, especially where surface water easily drains into bedrock. It can quickly carry pollution long distances. Hydrologists try to map these underground rivers to help protect fragile ecosystems. As Stephanie Hemphill reports, the first step in making these maps is a process called dye tracing.

When the snow is melting in the woods and fields, Jeff Green wants to know where it’s going.

“We’re going to hike back to two springs.”

Green is a hydrologist with the Minnesota Department of Natural Resources, and an expert in the limestone geology of Southeast Minnesota.

Green climbs a fence and splashes through a stream that’s flooding a pasture. The stream is bordered by a natural wall of limestone.

Melting snow seeps into the limestone. It runs down vertical cracks to bigger horizontal openings that look like miniature caves. Jeff Green calls these “conduits,” and some are three inches wide.

“You can imagine a pipe that big — water would move very fast, like we’re seeing. So these conduits are what we’re dye tracing.”

Green has traipsed out to this pasture to put what he calls a “bug” in a spring. The ‘bug’ is a small mesh bag about the size of a cellphone, packed with charcoal. The charcoal will capture a dye that he’ll pour into melting snow in a sinkhole a few miles away. He’ll do this in several different spots.

By tracing the paths of different colors of dye, he’ll learn the sources of the water that feeds each spring. That will help him make what he calls a springshed map.

We slog across a corn field that’s dotted with small groves of trees. They’re growing around miniature canyons, about 20 feet deep. Here, you can see how this honeycombed water highway works, and this is where Jeff Green will pour the first dye.

“This is a place where there was a conduit, an opening in the limestone.”

Green climbs down carefully into the crevasse.

“Listen! … All right!”

He’s found some running water.

“Water’s running right here. I don’t know where it’s going but it’s going someplace. So I’m going to try pouring dye here.”

He pours a cup or so of a bright red fluorescent dye into the snow.

Green marks the spot with a GPS unit. This is a place where surface water and groundwater meet.

“That snow-melt is surface water, it’s going into this sinkhole and it’s becoming groundwater as you’re listening to it.”

That means what happens here on the land directly affects the quality of the groundwater.

“In this case, it’s pretty good, you’ve got conservation tillage, lots of corn stalks left to keep the soil from eroding, and then you’ve got grass, permanent cover, around the sinkholes. So this is actually really good.”

There are wonderful trout streams around here. The map Green is making will help protect those streams by pinpointing the source of the water that feeds them.

In a day or two, Green will check the “bugs” he put in the springs, and find out exactly where the dye from this sinkhole went.

He usually finds water traveling one-to-three miles underground before it surfaces.

When the springshed map is finished, he’ll share it with local governments, farmers, and people who want to protect the water in this landscape.

You might think the flu season is over, but H1N1 flu is still around. Rebecca Williams reports health officials still want you to get vaccinated against the virus:

H1N1 flu peaked in the U-S last October and November.

The Centers for Disease Control and Prevention estimates through the middle of January, 57 million Americans got sick and 12-thousand people died.

Right now, most of the people getting sick with H1N1 are in the Southeastern U-S.

Tom Skinner is with the CDC.

“We wouldn’t be surprised to see activity continue into the spring and early summer. How much activity we may see moving forward into the fall and winter it’s just hard to tell.”

He says anyone who hasn’t gotten the vaccine should. Especially people with the greatest risk of complications from the flu. Those are pregnant women, kids younger than 5 years old and adults older than 65.

This fall, the H1N1 vaccine will be combined with the regular flu shot.

Decision Coming on Cape Wind

  • Bill Eddy of East Falmouth, Massachusetts, built his own schooner, and would one day soon like to sail through the proposed wind farm known as Cape Wind. (Photo by Curt Nickisch)

A decade-long fight over a proposed wind farm off the coast of Massachusetts could be over soon. It’s called Cape Wind. U.S. Interior Secretary Ken Salazar says he will make a decision by the end of April. What would be the nation’s first offshore wind farm is bigger than a simple “not in my backyard” issue. It has divided communities and even neighbors. Curt Nickisch met two people, who’ve come down on opposite sides – both for environmental reasons.

A decade-long fight over a proposed wind farm off the coast of Massachusetts could be over soon. It’s called Cape Wind. U.S. Interior Secretary Ken Salazar says he will make a decision by the end of April.

What would be the nation’s first offshore wind farm is bigger than a simple “not in my backyard” issue. It has divided communities and even neighbors. Curt Nickisch met two people, who’ve come down on opposite sides – both for environmental reasons.

At 63-years-old, Bill Eddy has old-man-and-the-sea white hair. He’s been sailing all his life, including the waters where the 130 wind turbines would go up more than five miles offshore. He knows the wind’s power. And he’s willing to give up part of the horizon he loves for clean energy.

“I have a firm, firm belief. We may have to for one generation be willing to sacrifice a very small portion of a coastal sea off the coast of Massachusetts. To launch this new future.”

Cape Wind would generate three-quarters of the electricity used by Cape Cod and the islands of Nantucket and Martha’s Vineyard. Bill says it’s time for residents here to share in the sacrifice for the energy that drives modern life.

“Consider for just a moment the sacrifice that’s already being made by the thousands of our fellow American citizens who live where their mountains are being removed for coal. Or what about the thousands of American men and women who are serving overseas to protect the places where the oil is that we import? To be honest with you, the 130 turbines of the wind farm, I’d prefer any one of them to one more marker in Arlington National Cemetery.”

“It’s not going to make any difference, this one wind farm.”

Martha Powers is just as passionate about Cape Wind, but she’s against it. She lives by the water, too.

“So this was a summer cottage, my Dad bought it in 1958.”

As a kid, Martha spent summers here. Now she’s a librarian with graying hair. She keeps binoculars by the back porch for birdwatching.

“This project would tear a big hole in that whole web of life there that could never be repaired. It would tear a hole that big under the ocean, all of the animals that live in the ocean beneath that water, and that fly above that water, it would be horrific. I can almost see it, like a bomb, to me, it feels.”

Mainly, Martha’s worried about the birds that will be killed by the spinning blades of the wind turbines. Her Christmas card this year was a photo of a chickadee perched on her finger.

“When you feel those little feet on your hand, trusting. It’s an amazing experience. So to kill them is just such a horrible thought. That’s the hardest thing for me to accept about this project.”

A few miles away, Cape Wind supporter Bill Eddy says it would be hard for him to accept the project not going forward.

“I know, I just know that, in a year or so, I’ll be able to go out to the wind farm. The wind in my sails and the winds in the blades of the turbine, that something very old and something very new is bringing about a most wondrous evolution.”

Whether that evolution starts off of Cape Cod will be up to someone in Washington. Interior Secretary Ken Salazar says the nation will move ahead with wind farms off the East Coast. But since people like Bill Eddy and Martha Powers can’t agree, Salazar will decide whether Nantucket Sound is the right place to start.

Drilling for Climate Change

There’s been lots of speculation about why President Obama is allowing expanded gas and oil drilling offshore. Many environmentalists don’t like it. Lester Graham reports the move might be part of a larger strategy to get a climate bill passed in the Senate.

Transcript

There’s been lots of speculation about why President Obama is allowing expanded gas and oil drilling offshore. Many environmentalists don’t like it. Lester Graham reports the move might be part of a larger strategy to get a climate bill passed in the Senate.

President Obama never ruled out expanding drilling offshore, but it still caught a lot of people off-guard last week when he lifted the moratorium. John Prandato thinks he knows why he did. Prandato writes for the Partnership for a Secure America. In a recent article he argues it’s about the climate change and energy bill being pieced together by Senators John Kerry, Joesph Lieberman and Lindsey Graham. Senator Graham has said a carbon cap-and-trade scheme such as the one in the House climate bill… is dead in the Senate. But maybe not… now…

“Graham has been a proponent of offshore drilling and he has said any climate change and energy bill would have to include expanded offshore drilling, which Obama has now made that concession. So, with any luck, this concession could revive cap-and-trade in the Senate. But, we’ll just have to see.”

Senator Graham says offshore drilling should be expanded further. The White House says the President is not “horse trading” to get a climate bill out of the Senate.
