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.

The Environmental Protection Agency
is holding up nearly 80 permit
applications for coal mining projects
because of concerns about about water
quality. Tamara Keith
reports this is creating a different
kind of concern in Appalachian coal
country:

The applications involve mountain top removal coal mining. Explosives are used to get at coal that’s close to the surface.

In the past, the mining companies have been allowed to fill in valleys with the leftover rock and dirt. But the EPA is concerned that streams are getting buried and polluted so the agency is now giving that practice a serious second look.

Carol Raulston is with the National Mining Association. She says holding up those permits have people in the mining towns of Ohio, West Virginia, Kentucky and Tennessee worried about losing their jobs.

“You really can’t operate these mines and employ people at them unless you’re able to construct the fills and in many of these communities they are the sole employer.”

An EPA spokesperson says protecting drinking water and coal mining jobs are both important. The agency says both can be done.

companies for mountaintop
removal coal mining. Lester
Graham reports a lot of people
expected the Environmental
Protection Agency to block
new mountaintop removal mining
in Appalachia:

Environmentalists say this is the most environmentally destructive kind of coal mining there is. It blows off the tops of mountains, fills in valleys, pollutes creeks and water supplies.

But the EPA does not have the authority to block it with no reason. The agency has to follow the permitting process in place.

Oliver Bernstein is with the environmental group the Sierra Club.

“They are operating under a fundamentally flawed legal framework around mountaintop removal and so the Obama Administration will need to take the bold steps to enact the rule-makings that will help to end this process completely.”

Environmentalists are calling for the White House Council on Environmental Quality to step in and do whatever is necessary to stop the mountaintop removal coal mining.

Saving With a Smart Grid

The government is spending billions of taxpayer dollars on a new “smart grid.” Mark Brush reports the new grid could eventually save you money on your energy bills:

Right now – power just goes from point A to point B.

But with a smart
grid system, your house can talk back to you and the power station.

The
meter could tell you how much it costs to heat your water, for instance.

And the power company will be able to talk to you if they’re having a
problem.

So, if they’re headed for a blackout, they can text message you
or e-mail you and ask you to shut off your A/C.

Jesse Berst is the founding editor of Smart Grid News dot com. It’s a trade publication.

He says, if electric grids are updated across the country, it would cut
down on pollution and save money.

“And that means there’s billions, tens of billions of dollars of power
plants and lines that we wouldn’t have to build over the next couple of
decades.”

Upgrading the system won’t be easy.

Each state has regulatory agencies that oversee thousands of electric
suppliers.

So there will have to be a lot of coordination.

Mountaintop Mining (Part One)

One of the last things the Bush administration did was change a rule to allow coal mining companies to dump debris into streams. That means one mining company will be able to remove one of the last mountaintops in a West Virginia county. Sandra Sleight-Brennan reports:

Gary Anderson takes me out on his back porch and all you can see is Coal River Mountain. Even on a cold, gray winter day, it’s beautiful.

“All of that mountain range of there, that is Coal River Mountain– that mountain runs for about 3 miles up there.”

When he retired, Gary and his wife Barbara moved from Connecticut back to her family home in Colcord, West Virginia.

“That’s basically what brought us back. Is the mountains and the beauty. We grew up here and we came back to spend the rest of our days here. We thought were coming back to what we remember– the beautiful mountains. And really they just started doing the mountaintop removal over here in the past couple years.”

Other mountains in the area– Cherry Pond Mountinan and Kayford Mountain have been flattened so energy companies could get to the coal inside them.
Over one million acres in West Virginia, Virginia, and Kentucky have already been leveled to mine the thin vein of coal.

The mining companies dynamite the tops off to get to the coal underneath.

“Once in awhile you’ll see a big puff of dust go up in the air like a bomb has been dropped and in awhile it will settle down and then it will happen again the next day.”

Mountains are shorted and flattened–- often by 100’s of feet to get to a 14-inch seam of coal. What the dynamite loosens is dumped in the valleys. Thousands of miles of streams have been covered over and nature destroyed.

It’s pretty simple. They put dynamite in the mountain and blow it up.

Joe Lovett is the Executive Director of the Appalachian Center on the Economy and the Environment. He’s been fighting mountaintop removal for the past 10 years.

It’s like a layer cake. The mountain is like a layer cake and that coal is the icing. The dirt and rock in between is the cake. There is a lot more dirt and rock and mining waste than there is coal. And when they blow up the mountain the dirt and rock swell. So they have even a bigger problem because they have more material than they know what to do with. So, as they blow the mountain up they need to find something to do with the dirt and rock and they dump it into the streams and the valleys.

Dumping into streams was stopped. The Surface Mining Act’s Stream Buffer rule protected the streams. But the new Bush administration rule changes that.

Joe Lovett says that Coal River Mountain fair game for Massey Energy to blow the top off and fill the valleys.

“We have always believed that the rule prevented these fills, that and I guess so did the coal industry and the Office of Surface Mining because this has been the main thing that the coal industry has wanted from the Bush administration for a long time is that change in this rule.”

Lovett says its not good for the environment and it’s not good for the local economy.

“We are taking mountains that could support sustainable timber jobs for generations and, in a few short years, destroying them forever and mining them in such a way that those forests will never come back.”

The mining industry argues that we need this inexpensive energy source in order to be energy independent. But, says Lovett and other environmentalists, if valley fills were outlawed tomorrow the cost of coal for our electric rates would only go up by pennies.

I’ll also talk to an official of the mining industry about why this type of mining needs to continue. The fact it provides American energy and jobs and that West Virginia’s economy depends upon it.

Back at Gary Anderson’s home, he wonders how it came to this.

Who gave them the right to blow the tops of mountains off to get the coal? I mean, that’s what gets me. Where, back in time, did they get the permission to come in and just below the mountains up? It’s really unbelievable. You can’t go back and reconstruct a mountain that’s been here for hundreds of millions of years. Once they’re gone, they’re gone.”

But, the mining companies now have the legal right to level the top of Coal River Mountain and fill up the valleys and streams above Anderson’s home.

Paying for Peak Power

Energy prices are rising, and people are looking
for ways to conserve power. But some rate payers are
saving money without actually cutting their energy use.
Instead they’re changing when they use power. Samara

Energy prices are rising, and people are looking
for ways to conserve power. But some rate payers are
saving money without actually cutting their energy use.
Instead they’re changing when they use power. Samara
Freemark reports:

It’s Saturday morning, and Ellen and Peter Funk are doing laundry.

The Funks used to do chores when most people do – they would get home from work and
switch on their dishwasher, dryer, and computer. They never really paid attention to
what that meant for their electricity bill.

“I never thought about electricity before. Never, never, never. Except when I got the bill.
But, you didn’t have any control. Because you paid the same price whether you used it at 2 in
the morning or 2 in the afternoon.”

But a couple of years ago the Funks started paying for their electricity differently than the
rest of us. They live in one of only a handful of buildings in New York City that
participate in a Real Time Pricing program.

Real Time Pricing charges consumers a different rate depending on when they use power.

The Funks know that running their dishwasher or turning on a light will cost more at 5
pm than at 10 pm. That’s because they get a color-coded chart every month that breaks
down their energy prices by time block.

“The green here is low. And the green starts at 10 o’clock at night and goes through 1
o’clock the following afternoon. The yellow is medium from 2 to 5 every day. And then
Monday to Friday there’s a high period from 5 to 9. That means stop. I think that’s why
they used red.”

It’s the same concept that makes cell phone minutes cost more during the day. Power
costs more when more people want to use it.

Real Time Pricing can save consumers a lot of money. Peter Funk says his family saves
hundreds of dollars a year by just shifting when they use energy.

“It’s an ongoing savings. We do these things because they make sense economically. We
don’t do it because we’re virtuous, we don’t do it because we’re better than our neighbor.
We just, this is the way we buy electricity because it makes sense.”

Real Time Pricing programs shift around power demand, so fewer people use energy
during peak hours. A Department of Energy study earlier this year estimated that Real
Time Pricing programs could cut peak energy use by about 15%.

That could actually help regions improve air quality and conserve resources by
decommissioning old, polluting power plants. Here’s how.

Most areas have a network of power plants. Usually only a few of those plants – the
newest, cleanest ones – are in use. But when energy demand peaks, the older, less
efficient plants kick in. And those plants spew a lot of carbon dioxide and other
pollutants into the air.

“It’s really not the number of power of power plants, but the ones you have to turn on at
critical times.”

Jim Genarro is a New York City councilman. He also chairs the council’s Committee on
Environmental Protection.

He says the plants that kick in when demand peaks are the worst in the system.

“We have a lot of reserve capacity in the city, but these are the older, dirtier plants, and
when you run those at peak capacity, it really means a lot of pollution.”

And Genarro says those plants cost even when they’re not producing energy. The city
has to maintain them all the time so they can switch on when needed. That wastes energy
and resources. It also means there are power plants that are only used a few weeks, or
even days, a year.

If power companies could cut peak energy demand, rarely-used, polluting plants could
become totally unnecessary. And many could be shut down.

Teachers Rap for Energy Conservation

They say that charity begins at home. So does energy conservation. At least,
that’s the idea behind a new program designed to get children interested in
saving energy, one light bulb at a time. The Great Lakes Radio Consortium’s
Chris Lehman reports:


All of German Valley Elementary School’s 100 students are gathered in the
gymnasium to learn about saving the world…


“You guys are the ones who are going to have to worry about this stuff down
the road as you become adults and go out into the world. We always want to
plan, don’t we fifth grade.”


“Yes.”


These kids are about to get a lesson in saving the planet. Although German
Valley Elementary is surrounded by farmland, the students are going to be
treated to a rap concert as part of that lesson. Their teachers are the rap stars,
trying to drive the message home…


(Sound of teacher rap skit)


The unusual school assembly is the kick-off event in a program called PEAK,
which stands for Preserving Energy for All Kids. It’s funded by a legal
settlement against one of the biggest power companies in Illinois: ComEd.
An audit found ComEd under funded its infrastructure. As part of a court
settlement, money was set aside to encourage energy conservation.


David Kolata is Executive Director of the Citizen’s Utility Board. The
consumer advocacy group is one of the agencies charged by the courts with
dispersing the 16 million dollar ComEd settlement.


“The mandate is simply to use that money to reduce our energy usage as
much as we can. We’ve taken the approach that there are multiple programs
out there that makes sense and we’re trying to see…basically pilot programs
to see what works and what doesn’t.”


So, German Valley Elementary is a testing ground. The school was
recommended by State Representative Jim Sacia. Sacia says educational
programs such as PEAK are crucial as younger generations face growing
questions about energy shortages in the future.


“I think it’s just so important that they learn at a young age the importance of
conserving energy and to consider alternative energy sources so that they can
make the world a far more energy-efficient place in years to come.”


The PEAK program includes more than school assemblies and teachers
mimicking rappers. The bulk of the lessons take place in the classroom…


(Sound of classroom presentation)


Teachers at schools participating in the PEAK program use teaching
materials generated by a California-based organization. One of the first
lessons is about the difference between standard light bulbs and compact
fluorescent light bulbs. Those bulbs use about one-third of the energy of a
standard incandescent light bulb, and can last up to ten years.


Students are given an assignment: to go home and count all of the light bulbs
in their house. Then they’ll figure out how much money their parents could
save by switching to compact fluorescents.


The PEAK program is in its beginning stages at German Valley Elementary,
but the message of energy conservation seemed to be hitting home with fifth
grader Brian Kraft:


“Because if we’re older and we don’t have any energy there will be nothing
to do and see.”


“How do you want to save energy yourself?”


“Turn lights off, play outside more than play inside.”


Playing outside means less TV watching and video game playing… and that
saves energy too.


Fifth grade science teacher Robert Nelson says the initial phase of the PEAK
program has generated positive feedback from children and their parents.


The school intends to sell compact fluorescent bulbs as a fundraiser later in
the school year.

Harvesting the Wind (Part 1)

  • Wind turbines can be both a blessing for farmers, as a source of extra income... and annoying to the neighbors. (Photo by Lester Graham)

Wind farms of huge turbines are springing up along coastlines,
windy ridges and blustery farmland. Most of us see them from a distance.
The Great Lakes Radio Consortium’s Chris Lehman recently visited some
of them up close… and has the first of two reports on wind energy:

Wind farms of huge turbines are springing up along coast lines, windy ridges and
blustery
farmland. Most of us see them from a distance. The Great Lakes Radio Consortium’s
Chris
Lehman recently visited some of them up close… and has the first of two reports on
wind energy…


If you can imagine the sight… there are 63 wind turbines scattered across the
prairie farmland,
their huge blades sweeping around, capturing energy from the wind. Each turbine is
213 feet
high. You can see them from miles around. But it isn’t until you stand directly
underneath the
80-foot long blades as they rotate in the wind that you begin to appreciate their size…


(sound of wind from underneath turbine)


“This is probably a typical day. They’re probably producing at about 30 percent of
what they are
rated at, and probably on average, for a year, this is what you’d expect.”


Christopher Moore is Director of Development for Navitas Energy. The Minnesota- based
company opened the Mendota Hills Wind Farm in northern Illinois just over a year ago.


Q: “What are some of the highest levels that you’ve reached?”


“Each turbine is capable of producing 800 kw, and there are times when we’ve had the
windfarm
working at about maximum.”


Moore says the Mendota Hills Wind Farm produces enough electricity to power about 15-
thousand homes per year. It’s the first wind farm in the state of Illinois.


Brian Lammers is a Project Manager for Navitas Energy. He says the location is
ideal since it’s
windy here nearly all year long…


“The wind here is more robust in the fall, winter and spring. So we have more
production during
those months than we do during June, July, August.”


Unfortunately, the summer months are the months that most often experience peak
demand for
electricity. Because of that, and because it takes so many windmills to generate
lower amounts of
power, it’s unlikely that current wind energy will completely replace fossil fuel
generated power.


(sound of turbines)


On the flat prairies of Illinois, the giant turbines are the tallest structures for
miles around. You
begin to wonder about things like lightning strikes…


“We might have experienced one or two last year. The turbines are protected from
lightning. The
entire wind farm is grounded, so if there is a strike typically it will just be
grounded down to the
ground grid. There’s typically no long-term damage associated with a lightning
strike. But as you
can imagine, they’re the tallest structures around so there are periodic lightning
strikes.”


Q “What about a tornado? This is tornado country…what would happen if one came
through
here?”


“I don’t know. These turbines are built to withstand everything but a direct strike
from a tornado,
so I think the same thing would happen to a wind turbine that would happen to any
large
structure if they were struck by a tornado. You’d probably have some significant
damage.”


(fade up sound inside turbine)


Inside the turbine, there’s a distinct hum as the blades whirl away at the top of
the hollow shaft.
It’s about ten feet across at the base, and a metal ladder allows anyone brave
enough to climb all
the way to the top.


Despite the hum of the turbine’s blades up close, the sound fades away just a few
dozen feet from
the tower. But noise isn’t much of a concern for this wind farm. It’s in the
middle of a soybean
field and there are no neighbors nearby.


Noise is just one of the aesthetic concerns for neighbors of wind farms. Appearance
is another.
The Mendota Hills turbines are coated with a special paint that appears white in
bright sunshine.
But when the sun’s not out, the turbines appear grey, and seem to blend in with the
cloud-covered
sky.


Dennis Cradduck has 19 of the turbines on his corn and soybean farm. He says the
wind farm
hasn’t been a problem. Of course, he’s getting paid by Navitas for allowing the
turbines on his
land. But he says the wind farm has led to an unexpected benefit: getting to meet
people from
across the country who pull off the highway for a closer look…


“We get people almost on a daily basis that drive by on the interstate and see them,
and stop and
want to look at them, and they’re amazed at them, and most—about 99 percent of them
have been
positive comments. In fact, one fellow from North Carolina stopped the other day
and said ‘I wish
we’d build more of these around the country because we need renewable energy.'”


The prospect of more renewable energy is appealing to most environmentalists. But
some worry
that wind farms can be deadly to birds. A study by the National Wind Coordinating
Committee
found that wind turbines kill an average of two birds per year.


Another concern is that windmills disrupt the scenery. But the only view around
here is farmland
as far as the eye can see. And on this brisk day, it isn’t just corn and soybeans
being harvested: it’s
the power of wind.
