Some electric companies are working
to put smart meters on our homes.
They want to change how we use
electricity hour by hour. Eventually,
power companies will charge more
when demand for electricity is highest.
Mark Brush reports on a new study
that looks at how people are responding:

Connecticut Light and Power tested the smart grid on about 3,000 of it’s customers. Half of them residential and half of them business customers.

They found that people did respond to high rates during high periods of demand – such as from noon to eight pm.

Jessica Cain is with Connecticut Light & Power. She says there seems to be a limit to how much they’ll change. For example, doing laundry late at night seemed to be a non-starter.

“Doing your laundry after 8pm would be a barrier. And we heard that from customers, both from a residential customer side and then from a business customer side. We heard that changing their business hours outside of that twelve to eight window would be very difficult.”

The power company found the most energy was saved when the utility itself used the smart meter to shutdown things like air conditioners during periods of high demand.

The customers said they liked the “set it and forget it” approach – so long as they could override the system if they needed to.

Climate change has already brought
warmer temperatures, rising sea
levels and melting glaciers. Now,
researchers believe global warming
will cause major shifts in wildfire
patterns around the world. As Sadie
Babits reports, scientists hope to
predict where future wildfires will
light up:

Trying to predict where wildfires are likely to start decades from now, is
kind of like getting a full body scan.

(sound of medical scanner)

Except instead of a medical scanner, scientists scanned the earth using
satellite data, climate models and the history of present day wildfires to
map out global wildfire patterns.

“The impacts of climate change on wildfires are expected to be widespread
around the world.”

Katherine Hayhoe is a climate scientist at Texas Tech University. She’s part
of a group of scientists that has for the first time, tried to project where fire
hotspots will crop up around the world. She says they found that climate
change will affect wildfire patterns.

Hotter temperatures and rain and snow coming at different times in the
year or perhaps not at all, will mean forests and grasslands will dry out
quicker – becoming tinder boxes for fire.

In the next 30 years, scientists believe that the Western U.S. will continue
to see catastrophic fires like the recent blaze in Santa Barbara, which
destroyed 80 homes.

In the next 60 years, they predict wildfires will increase in the Corn Belt and
spread into the East Coast.

Hayhoe says having an idea of how wildfire patterns will shift will help
communities better prepare.

“We can never eliminate the risk of climate change entirely but by making
wise choices and planning strategically we can minimize those risks.”

Some communities are already taking steps to prevent wildfire. The city of
Bend, Oregon was one of the first in the country to launch a public
education campaign to get homeowners to fire proof their homes. The
program, called FireFree, started more than a decade ago, after a massive
wildfire burned nineteen homes and scorched thousands of acres.

“It was something that scarred our community.”

Gary Marshall is the deputy chief of Bend’s Fire Department.

“We have this history of people wanting to live outside the urban area and
live out in rural areas, where they can see the deer and be out in the trees
and live that lifestyle that most Americans who move out to the West want
to be a part of that.”

Bend lies in what’s known as wildfire alley. Every year there are dozens of
fires that crop up either from lightning strikes or from people. The flames
are fed by dried out grasses and forests so dense you can’t see through
them. Add homes to the mix and you have a recipe for disaster not just
here but throughout the West.

But Marshall says the Fire Free program is working.

(sound of a truck driving on a dirt road)

County forester Joe Stutler and Gary Marshall drive me through
neighborhoods outside Bend. We stop first at an upscale suburb called
Coldera Springs. Everyone here has volunteered to fire proof their new
homes.

But just down the road, there’s a much older suburb and a lot of trees that
have been thinned out.

Sadie: “You can’t see through the trees it’s so dense.”

Joe: “You can’t walk through.”

Gary: “And a firefighter won’t go in there. You’d write that off. So if you
don’t take care of it, the fire will.”

That’s a picture that climate scientist Katherine Hayhoe hopes to avoid.
She says having a long term view of where wildfires might pop up could
help communities to start now and follow Bend’s lead.

It took Bend years to get most of the homeowners here to take
responsibility, and give their homes a fighting change to survive a
devastating blaze.

Fighting Over Oil and Water

In the future, keeping your gas tank full could make disputes over water in the American
West a lot worse. It’s because energy companies hope to develop the oil shale industry.

In the future, keeping your gas tank full could make disputes over water in the American
West a lot worse. It’s because energy companies hope to develop the oil shale industry.
Getting oil from shale requires lots of water, and the richest oil shale deposits happen to be
in the dry state of Colorado. Shawn Allee headed there to see why a fight over water and
oil could be in the works:

Oil companies have their eyes on vast oil shale deposits in western Colorado, Utah and
Wyoming.

The federal government says companies could pull 800 billion barrels of oil out of that shale.

That’s about three times the proven oil reserves in Saudi Arabia.

Oil shale’s an impressive resource but it depends on water and there’s not much available
there.

How much would an oil shale industry need?

Shell Oil PR guy Tracy Boyd says the simple answer is that it will likely take his company
three barrels of water to extract one barrel of oil.

It’s because oil shale doesn’t really have oil in it – it’s got something called kerogen.

“You can heat this kerogen up. If you do it really slow, which we do for about 3.5 –
4 years, by putting heaters down in the rock formation, (you) produce a crude-oil
like material but with a little processing this is the first product we get out of it
which basically transportation fuels.”

Heating the ground require loads of electricity from new power plants and generators, and
they’d be cooled by water.

Oil companies are just experimenting with shale right now, but they’re securing rights to
water just in case.

Shell’s latest water claim is on Colorado’s Yampa River.

When Shell filed its court papers – some town governments warned they might fight the
claim.

One of these towns was Parker – a Denver suburb hundreds of miles east of the oil shale
region.

Frank Jaeger runs Parker’s water district.

Jaeger says, like other Colorado cities, Parker plans to expand.

“We know approximately what our numbers are and it will be somewhere in the
neighborhood of 150,000 people. In order to assure 150,000 people for another
150 years from now, I have to be proactive, I have to be at the front of the line for
the next drop of water available in the State of Colorado.”

Oil shale developers and cities across Colorado are set to fight over the water they might
need for the future, but some feel oil companies already have an edge.

“They’re actually one step ahead of the game.”

David Ableson is with Western Resource Advocates, an environmental group.

Ableson says energy companies tried developing oil shale several times in the last century.

They failed, but each time, they bought more water rights – just in case.

Now, they’ve got loads of water rights – and if the industry takes off, they’ll use them.

That could stop cities like Denver and its suburbs from getting water they hoped to have for
new homes and businesses.

Ableson says this isn’t just a Colorado fight, though.

He says some congressmen sell the idea of oil shale as an energy source the whole country
can depend on – even though its future could get tied up in Colorado water courts.

“And so, folks who are looking at this issue who do not live in CO, UT, or WY, need
to understand that when an elected official says, “this can solve our energy woes,”
that it’s actually a far more complicated situation than that and if there are severe
water impacts, that makes it much less likely that you could develop that
resource.”

The energy industry claims the concern over water is overblown – they say they just might
not need all that much water.

Ableson says that’s only true if oil shale fails. But if it succeeds, and we fill up on oil shale
gasoline – he predicts some towns or industries in the West will be left dry.

Getting Water to the Dry, Dry West

  • Colorado Springs pumps water through the Rocky Mountains into town (Photo courtesy of the Colorado Springs Convention and Visitors Bureau)

Out West, a lot of cities figure many more people will be moving in over the next few decades. Water engineers wish those people would bring along all the water they’ll need, but of course they won’t. Shawn Allee reports these cities want to pipe more water from far away, and some people think that’s a bad idea:

Out West, a lot of cities figure many more people will be moving in over the next few
decades. Water engineers wish those people would bring along all the water they’ll
need, but of course they won’t. Shawn Allee reports these cities want to pipe more
water from far away, and some people think that’s a bad idea:

The air in Colorado Springs is usually so dry it quickly chaps your lips.

What gives? Colorado Springs sounds wet enough.

“There’re really no springs in Colorado Springs, so when you start talking
about water, it’s a divergence between our name and reality. Sounds like we
had a lot, and in reality we didn’t.”

This is Matt Mayberry, Colorado Spring’s historian.

I’ve heard about this massive water pipeline project the town’s cooking up, and I was
curious just how long the city’s worked to quench its thirst.

Mayberry’s got an exhaustive book on that with an exhaustive title.

“Blah, blah, blah … the emergence and appropriation of rights in Colorado
Springs.”

The crib notes version?

Early on, buffalo manure poisoned Colorado Spring’s creek, so people dug wells.

Then, the wells got infested with grasshoppers.

And the town grew, and grew, and grew again.

“Very soon you had to bring water from further away, and ultimately to the
Western Slope which is a couple hours drive of here.”

Today, Colorado Springs pipes water through the Rocky Mountain range.

Doing the extraordinary for water is kinda ordinary for Colorado Springs.

Its latest pipeline project is called the Southern Delivery System, and it’ll pump nearly
80 million gallons into town each year – and it’ll pump that water forty five miles –
completely uphill.

Impressive, but some people are asking tough questions about it.

“Our concern with this project is the greenhouse gas emissions that it would
contribute to.”

Stacy Tellinghuisen is with Western Resource Advocates, a Colorado environmental
group.

She says there’s a connection between pumping water uphill and a large carbon
footprint.

“Water is heavy. Pumping it over a great distance takes a lot of energy, and
in the process it would require something along the lines of 60 MW of power,
which is about a tenth of a power plant.”

And, for the most part, the utility burns natural gas and coal to generate power. Both
emit carbon dioxide, a greenhouse gas.

Tellinghuisen says Western cities are considering at least five other water pipeline
projects, some with even larger carbon footprints.

She wants Colorado Springs to set an example by using dedicated low-carbon sources
like wind power for its water pumps.

I ask the Colorado Springs Utilities about that.

Keith Riley helped plan the Southern Delivery System.

“We think there are some ways we can minimize the carbon footprint by
looking at some new technologies.”

Riley says there were lots of environmental regulations to wade through before the
Southern Delivery System got approved.

But a large carbon footprint doesn’t disqualify utility projects.

Riley says, even if carbon were considered, the project might have gone forward
anyway because the city’s expected to grow over the next few decades.

“Water is the essential element for all of us, so when it comes to that level of
sustaining our own lives, then you get to some trade-offs on what we’re
willing to do to keep ourselves alive where we we live, where our cities are.
No matter what happens, we’ve got to move water to Colorado Springs, and
we’re uphill from the river, so we’ve got to get the water uphill one way or
another.”

Riley says Colorado Springs Utilities is considering low-carbon renewable power for its
new pipeline.

But it’ll be expensive, and no one’s stepped forward with all the money.

Other Western cities are engineering clever ways of moving loads of water around,
too. And it’ll be a political and financial challenge for them to pay for the carbon
footprint.

Twenty years ago this year, the
country watched its oldest national park
go up in flames. Looking back, scientists
believe the 1988 fires of Yellowstone
National Park were the signal fire of
climate change. Researchers have been
working ever since to understand this
relationship between climate and wildfire.
Sadie Babits reports on two scientists
searching for clues to ancient climates,
using trees as their guide:

Jennifer Pierce wears work boots as she plows down a steep slope in a
ponderosa pine forest.

(sound of walking, twigs breaking)

Her blonde hair is tucked up under her Boise State bronco cap, but it keeps
sneaking out. She has to keep brushing it back under. She and her
colleague David Wilkins are professors who work for Boise State
University’s Geosciences Department. They’re in the middle of tall pines in
a forest just outside of Boise, Idaho. Suddenly she’s crashing across the
brambles and heads for this tree.

“Oh that’s a great one! Wow! Sweet!”

She drops to her knees and shows me how this tree has been scarred by
fire.

“You see this little V shaped cat face here at the bottom of the tree that’s
blackened? So during a fire when the bark of the tree gets damaged that
preserves a record of the fire as a scar on the tree.”

Pierce says since the tree has annual growth rings, she can tell when the
tree got burned.

It’s one way Pierce and Wilkins reconstruct the fire history of this forest.
It’s a key to understanding how climate has affected forest fires in the past.

“I think as we move into a likely warmer and drier future, it’s going to be
increasingly important to understand the relationship between climate and
fire.”

She says climate is the primary control for wildfires. As the West warms,
there’s less control. Recently, that’s meant a lot more wildfires.

(popping sound) “There you go!” (sound of a drill bit going through the tree
with sound of birds and forest)

David Wilkins is twisting an auger into the tree.

“It’s a good upper body workout!” (laughs)

It’s a way to take a sample of the rings of this tree. Within a half-minute,
Wilkins’ auger is stuck. The tree is rotten inside. An eight-inch core is all he
gets.

(sound of drill bit coming out of the tree)

Jennifer Pierce takes a look at this sample Wilkins twisted out. The rings –
some light, some dark – reveal just how the tree has responded to moisture
and temperature.

“If you have a tree that kind of is at the edge of its comfort zone so to
speak, it will be more of a sensitive recorder of those environmental
stresses. See this one looks pretty good.”

Tree rings aren’t the only clue these scientists use to reconstruct historic
climates.

(scraping sound)

“I didn’t bring my big shovel. I kind of feel naked without it.”

Pierce scrapes away dirt and she finds bits of charcoal. She can sometimes
use charcoal for radio carbon dating. But these won’t do.

“But, um, I wouldn’t use them for dating because you want to make sure
that the charcoal is stratographicly in place and that you haven’t had
critters burrowing and mixing things up.”

Charcoal can be dated much further back than the tree rings. It helps
Pierce and Wilkins understand what happened here thousands of years
ago. With samples from other scientists, they’ll get a snapshot of ancient
climate and how it affects wildfire.

And possibly determine what climate change will mean for forests in the
future.

Thirsty City Waits for Water Diversion Law

  • Diversion of water from the Great Lakes is a controversial issue. Many worry that diversion could affect life in the ecosystem. Others worry about obtaining sources of fresh water for drinking. (Photo by Brandon Bankston)

Great Lakes governors and their counterparts in Canada are working on a legal agreement called Annex 2001. The document will determine how water from the Great Lakes will be used and who gets to use it. Controversy has already erupted over the possibility of one city’s bid for the water. The city is looking toward the completed Annex for guidance. The Great Lakes Radio Consortium’s Christina Shockley reports:

Great Lakes governors and their counterparts in Canada are working
on a legal agreement called Annex 2001. The document will determine how
water from the Great Lakes will be used and who gets to use it. Controversy
has already erupted over the possibility of one city’s bid for the water.
The city is looking toward the completed Annex for guidance. The Great
Lakes Radio Consortium’s Christina Shockley reports:


Dan Duchniak says he’s an environmentalist.


“We have the low-flow showerheads in our house, we have the low-flow faucets, we have the high-efficiency washers and dryers, our kids know about those, you know, they think they’re fun.”


But Duchniak is in the middle of a bitter fight with other environmentalists and officials over his area’s largest natural resource: water from Lake Michigan. Duchniak is the water manager for the City of Waukesha, Wisconsin. It’s just west of Milwaukee. Waukesha is only about 20 miles from the Lake Michigan shore. Right now, Waukesha gets its water from wells that tap an aquifer deep within the ground. But Duchniak says the wells won’t sustain the long-term needs of the city.


“As the water levels drop, the water quality degrades, and what happens is we’ve seen an increase in different water quality parameters, one of those being radium.”


And radium is a health problem. In very high doses, radium can cause bone cancer. To solve its water problems, the City of Waukesha might ask for access to Lake Michigan water. But even though the community considers the lake part of its back yard, there’s a major problem. Even though it’s close, Waukesha sits outside the Great Lakes basin.


That means the area’s ditches and streams drain away from the lake. Rain water runoff and treated water from the sewer system flow toward the Mississippi River Basin. The governors and premiers might include a rule in the Annex 2001 that says communities sitting outside the Great Lakes basin must return treated water to the lake, if they use it.


Engineers who study water in the area say Waukesha could make the case that the city is already using Great Lakes water. That’s because the city’s wells tap into water beneath the surface that supply water to Lake Michigan. But environmentalists say that argument isn’t going to fly. Derek Sheer is with the environmental group “Clean Wisconsin.” He says Waukesha would be pumping a lot more water directly from the lake than the underground aquifer would replace.


“They’re not returning 13 million gallons of water back to the Great Lakes by any stretch of the imagination.”


But the city of Waukesha knows that if the finalized Annex 2001 looks anything like the early drafts, the city would have to return most of the water it uses back to the lake. Waukesha’s water manager, Dan Duchniak says that could be done in a combination of ways. The city could pump it back to the lake, pump it to a nearby stream that flows to the lake, or stop using the ground water completely and let it flow back to the lake.


People on both sides of the water issue seem to agree on one thing: because of the huge amount of water in the Great Lakes system, and its natural ebb and flow, the amount of water the City of Waukesha would take would not harm the Great Lakes’ ecosystem. Even if it’s not pumped back.


Art Brooks is a professor at the Center for Great Lakes Studies at the University of Wisconsin-Milwaukee.


“The amount of water they intend to withdraw would probably lower the level of Lake Michigan on the order of a millimeter or so, probably less that five millimeters per year.”


But it’s not just Waukesha that has environmentalists worried. Professor Brooks and environmentalist Derek Sheer say if Waukesha gains access to Great Lakes water, it could set a dangerous precedent. Sheer doesn’t want other states and countries to start withdrawing Great Lakes water.


“If Waukesha and Arizona and Georgia and all these other places start pumping large amounts of water out of the basin, we could see a dramatic lowering of the water in the lakes.”


The city of Waukesha says it needs the water and would abide by whatever the Annex 2001 agreement sets down. And Waukesha’s water manager, Dan Duchniak, says that includes what it determines about return flow. He says arguing about the issue right now is a waste of time, since the Annex isn’t done. Beyond that, Duchniak says Waukesha is part of the Great Lakes system, and is not about to suck the lakes dry.


“Lake Michigan is in our back yard. We can see Lake Michigan from here. We’re not that far away from it.”


The experts say Waukesha would only be the first in line to ask for Great Lakes water. With suburbs sprawling away from the big cities on the lakes more and more towns will be eyeing the Great Lakes when demand for water exceeds their underground supplies.


A draft of the Annex could be ready this year, but it will most likely go through a lengthy series of votes before it becomes law.
