Remember that huge blackout in the summer of 2003? Forty-five million people in the Midwest and Northeast US – as well as 10 million in Canada lost power. Julie Grant reports that the federal government and utilities are spending billions of dollars on what’s called a “Smart Grid” – in part, so we don’t have more large scale blackouts.

Right now, electric power in the U.S. is generated by a relatively small number of very big power plants. That power is transmitted all over the place.

But this set up is increasingly running into problems. The demand for power is skyrocketing: from big American houses and TVs, air conditioners and computers. The grid is struggling to keep up. And it’s not always succeeding.

There have been more – and more massive – blackouts in recent years than in previous decades.

Universities, private laboratories, and utility companies are all looking at different aspects of making the electric grid smarter.

Chris Eck is spokesman for First Energy, which provides power in Ohio, Pennsylvania and New Jersey. He says there are so many ideas on how to improve the nation’s electrical system.

“Part of the challenge is defining the smart grid. I think there are different opinions out there about what it will and won’t include.”

The Department of Energy says the smart grid will change the electric industry’s entire business model. Instead of being a centralized, producer-controlled network – it will transform to become decentralized and consumer-interactive.

Ken Laparo works on these kinds of issues at Case Western Reserve University in Ohio. He says a smart grid will get consumers more involved in planning their energy use.

“Right now, you have no idea what a killowatt hour is costing you in Cleveland on March 10 at 8:30 in the evening.”

Laparo says most of us just look at those little bars on our electric bills that show how much energy we used that month. But he says it doesn’t really mean much to us.

But companies are developing all kinds of products: smart plugs, smart thermostats, smart appliances, that tell you how much energy is being used – so customers can decide the best ways to reduce energy use – and to reduce their bills.

Utility companies might start charging more at peak energy times of day – and they will communicate those shifting prices to “smart” consumer devices in real time.

Laparo says these small slices of energy savings might not seem like a lot:

“But it’s the cummulative effect of what everybody is doing, no matter how small it is. When you add it up over millions of customers over days and weeks and months and years that the overall opportunity is huge.”

But there’s still a lot to be done. A decentralized system is going to need better communication. If every programmed refrigerator is constantly trying to optimize its energy usage based on the power’s moment-to-moment price — the electricity system will also have to be an information system. Each smart appliance and home meter, will have to be able to communicate with the energy companies.

If it works, this type of communication could help utility companies predict an overload on the power system – like the one that started the black out in 2003. Utilities today just predict when usage will be high. But a smart grid, they will actually know how high it is in real time.

Utilities will also have a better ability to fix problems in the system before they get out of control.
This is what some researchers call the Holy Grail of the Smart Grid. In the short term, they see consumers learning more about saving energy, and communicating that to the power companies. But in the long term, they want to be able to sense and manage the grid, to avoid those debilitating blackouts.

The 2003 blackout started because there was a high demand for power in one Ohio town. When that one generating plant went off line – it tried to get power from another plant, and overloaded the next plant, setting off a cascade of outages. More than 100 power plants shutdown that day.

First Energy spokesman Chris Eck says a smart grid could help prevent blackouts.

“As it is now, you might know you have circuits out and you have to send crews out to physically for a problem with these lines. With a smart grid, with enough sensors and feedback communication, you might be able to pinpoint before they get to the site. And they can isolate the problem and fix it quicker.”

There’s a new online map for tracking
wildlife diseases that threaten animals and
people. Chuck Quirmbach reports:

Diseases such as West Nile Virus, Chronic Wasting Disease, Avian Flu, and
others are now often in the news. A website partly developed by the US
Geological Survey aims to track reports of the disease outbreaks around the
world.

Veterinarian Josh Dein leads the project. He says he hopes both health care
professionals and the general public use the online map.

“One of the things you can do is say ‘what’s happening in my neighborhood,
what’s happening in my state, my country?’ And maybe I’m traveling to
someplace else. Maybe I want to look to see what’s happening somewhere else.”

Dein says the map also allows people to narrow their search to specific countries, types of
disease and affected species.

endangered Karner blue butterfly. Now these efforts could be helped by a
new computer mapping and statistical modeling technique. The Great Lakes
Radio Consortium’s Chuck Quirmbach has more:


Habitat maps for endangered species can be based on broad general
estimates. But some scientists hope a combination of computer
software and data such as soil type and vegetation will lead to
more accurate information on where the Karner Blue butterfly lives.


David Mladenoff is a professor of Forest Ecology at the University of
Wisconsin – Madison. He says having a better idea of the butterfly’s
habitat might save companies money on things like surveying costs.


“In other words, if they say we’re planning on doing work on this utility
right away or potentially harvest this area of forest, is this even
a place we have to be concerned about for the Karner Blue butterfly
occuring?”


The U.S. Fish and Wildlife Service, a state agency, and some power
companies are funding a computer mapping project in Wisconsin.
Scientists say the same technique could be used in other states.

Interview: Children’s Book Author on Great Lakes Woes

The Great Lakes were flowing with water
On every Great Lakes Day;
Until something frightful happened
And made the Great Lakes drain away.

That’s how the new children’s book, “The Day The Great Lakes Drained Away” begins. The author is Charles Ferguson Barker and he recently spoke with the Great Lakes Radio Consortium’s Charity Nebbe:

The Great Lakes were flowing with water
On every Great Lakes Day;
Until something frightful happened
And made the Great Lakes drain away.

That’s how the new children’s book, The Day The Great Lakes Drained
Away begins. The author is Charles Ferguson Barker and he recently
spoke with the Great Lakes Radio Consortium’s Charity Nebbe:


Nebbe: “Charles, in your book, all of the water disappears from the Lakes and you take us on a tour of all the lakebeds, so we see landforms and shipwrecks and a whole lot of mud… What gave you the idea to show kids what the Lakes would look like without water?”


Barker: “Well, actually, it was from looking at some maps that are put out by the National Geophysical Data Center that show, basically, what’s on the lake floors, and I, for one, had not given it much thought ’till seeing these maps. But these maps have some really cool features like ridges of rock and all kinds of neat stuff and I thought this would be a great idea for a children’s book.”


Nebbe: “What do you think some of the coolest features that you’ve been able to put into the book are?”


Barker: “Um, well, there’s a suspected meteor impact crater on the east side of Lake Ontario, and it’s not confirmed as a meteor impact crater, but a lot of other things it could be have been ruled out. So that’s pretty neat. There’s also, to me, what’s most exciting is the ridge of rock, or ridges of rock underneath Lake Huron, that, in some cases, have maybe four hundred feet of relief. And most of the maps we see of the Great Lakes are basically just a flat blue, so seeing what’s under the Lakes I thought was really exciting.”


Nebbe: “When I was reading the book, I thought, you know, if I were a kid, this would be pretty scary to me because all the water goes away from the lakes and, you know, there are fish dying in at least one picture. Why did you decide to show us the bottom of the Lakes in that way?”


Barker: “Well, actually, that’s pretty much how… the only way I could figure out how to show them, I mean, if we’re talking about features that are on the lake floors, then somehow we’ve got to get rid of the water to see those, and sort of… it’s a fanciful sort of draining away of the Lakes, if you will. The purpose of the book is almost twofold: one is to show that the lake floors are pretty cool, and there’s some neat features under there, but also to sort of reinforce that hey, we’d better make sure this never happens, you know, so it goes to the protection of the Lakes as well.”


Nebbe: “The culprit in your book is water usage among communities in the Great Lakes Basin and there are rules that govern water usage among those communities, one of them is that they have to return the amount of water that they use and that communities outside the basin can’t use the water without approval. Why did you pick that as the culprit?”


Barker: “Well, that’s a good question and it sort of goes back to the original manuscript draft, and I thought, well, gosh, the villain could be actually just everybody taking a little bit of water thinking that it doesn’t matter, but the cummulative effect of that mindset causes a problem, and I think that’s true, I work in environmental consulting, and I can attest that that’s basically how major contamination sites are created is that everybody thinking, ‘Oh well this one little thing won’t matter, this little drop of tetrachlorethyline won’t matter,’ but if everybody has that mindset, then, yeah there’s going to be a problem.”


Nebbe: “You’ve been talking to some of the kids who are reading the book, do you think that message is getting across?”


Barker: “Yeah, I think, you know, initially, they really kind of like to sort of see the pictures and hear and learn about the lake floors and whatnot, but I think it’s important to, you know, relay to kids that they’re actually going to be the ones making decisions down the road about Great Lakes withdrawals and whatnot, and recently, I was just talking to somebody and remembering back to when I was a kid, we used to sail a lot on the Great Lakes, and I remember being in the middle of Lake Erie, sort of out of the sight of land, and sailing through soap suds. It was terrible. I mean, Lake Erie was horrible. This was in the early seventies. And it was like you’re in a bath tub with soap suds. That’s more of a water quality issue, but I think it sort of became a problem because of nobody really, um, paying much attention. So, I think the more attention we pay to the Great Lakes, in terms of just making sure no wacky ideas about withdrawal go through, then that’s good. That’s what we need to do.”


Nebbe: “Charles Ferguson Barker, thank you so much.”


Barker: “Thank you.”
