Saving energy can be as simple as turning off the light switch when you leave a room. But in most homes… that doesn’t happen all the time. Lester Graham reports… motion sensing light switches are become more popular because they’ll switch on and off automatically.

In some families, Dad stomping around the house, turning off lights and yelling to no one in particular is legendary.

“How many times do I have to tell you, turn off those lights.”

Don’t burst a blood vessel there, pal.

Well, Dad might have had a point. Matt Grocoff with Greenovation.TV says he’s been poking around the Environmental Protection Agency’s website and found this:

“Sixty-percent of lighting actually goes to lighting an unoccupied room, hallways, bathrooms, your bedroom. Drive by any neighborhood house and you’ll see eight rooms lit. How many of those houses have eight people in them.”

Matt says there’s a solution. Motion-sensing light switches. They can be set to turn on when you walk into a room and turn themselves off when you leave… staying on for a minute or two… or five… or a half-hour. Whatever you set it to.

There are a lot of different types. Laurie Gross is President of Gross Electric in Ohio and Michigan. They’ve been selling lamps and lights and switches for one-hundred years.

She says there are light switches that turn on when you enter and off when you leave, others that you have to turn on and they turn off when the room is empty. Different technology works –well– differently. Gross says passive infrared works well for pantries or kitchens because they detect motion.

“Then there’s ultrasonic which doesn’t need a line-of-sight. So, those are good in public bathrooms so when it senses heat, when go in there, it knows you’re there and turns off if you take a little longer than expected to take.”

And there are switches that use both infrared and ultrasonic… good for places like big office spaces.

You can expect to spend 50 – 60 bucks or more for a good one, depending on what you want. There are cheaper sensor light switches out there… but in this case, you really do get what you pay for.

Now… these switches use a tiny bit of power themselves… so the best place for them is in a room where leaving the light bulb on is not likely to be noticed for a while. Matt tells the story of forgetting to turn off a light in the garage during vacation. That bulb burned for two weeks. A sensor switch makes a lot of sense in a place like that… or in a closet… or a room you don’t use a lot.

Matt Grocoff and his wife Kelly are working to make their 110 year old house the oldest net-zero energy home in America. And he says he loves having motion sensing switches in key areas for the convenience as well as the energy savings.

“We open the door in the kitchen and come through the door with loads of groceries and the light comes on automatically. You don’t have to do the elbow dance.”

His wife Kelly says for her… it’s avoiding a little childhood terror.

“I have a little PTSD from when I was younger and my Dad was constantly harassing us to turn the lights off. Now, I know if I leave the room and I don’t turn the light off, it’s going to go off eventually instead of having my Dad chase me down and giving me some lecture about turning the lights off, saving energy, saving money, blah, blah, blah.”

Funny story about that. Kelly’s Mom, Jane Casselman was visiting when I was at the couple’s house… and she started laughing about Dad lecturing about the lights.

“’Cause in the evening, yours truly would turn all the lights off before going to bed.”

Heh– busted.

Salt in the American Diet (Part 2)

problem. Julie Grant reports:

New research shows that Americans health would benefit dramatically if we ate less salt. But some people say it’s not the salt in the saltshaker that’s the problem. Julie Grant reports:

Darryl Bosshardt comes from a salt family. His grandfather started mining salt on their farm in central Utah. When Bosshardt hears about a new study that shows 100-thousand American lives could be saved each year if everyone reduced their salt intake by just a half teaspoon – he cringes.
He says salt is being given a bad name.

“And the challenge is, how we define salt.”

Most of the salt today all looks the same – perfectly pour-able, uniform bright white grains. It’s pure sodium and chloride, but Bosshardt, whose family owns the Real Salt Company, says it’s not the same as naturally occurring sea salt.

“Sea water occurs with many trace minerals. Over 50 to 60 trace minerals. It doesn’t occur, the salt in sea water doesn’t occur, as pure sodium and chloride.”

Bosshardt says those trace minerals help the body to process sodium, but most salt today looks perfect because the trace minerals have been taken out. He says when our bodies lack the minerals needed to process sodium; it raises blood pressure, which can lead to heart problems.

There are some books by holistic doctors that make these kinds of claims,but there’s not much science to prove this.

Most doctors today say salt is salt; sodium chloride. Our bodies need it, but not as much as much as most Americans are eating.

Dr. Kirsten Bibbins-Domingo is a professor of medicine and epidemiology at the University of California in San Francisco. She’s lead author of that new study on salt – the one that finds Americans could reduce deaths from heart disease by 100-thousand just by slightly reducing salt consumption:

“I don’t think we’re saying salt is bad and one of these other types of salt would be good. I think the newer types of salt that are on the market might have a lower sodium content for the taste that they have and so that would certainly be potentially beneficial.”

But Bibbins-Domingo says most Americans only get 6-percent of their sodium from their own saltshakers. The rest comes from processed foods and restaurants. So buying expensive sea salts with those trace minerals isn’t going to make much difference to most people. She says the problem is that salt is ubiquitous – people don’t even realize they’re eating it:

“If you start out with a healthy bowl of cereal with some milk, you’ve already consumed quite a bit of salt right there. If you have that healthy turkey sandwich or tuna sandwich, you have a bit of salt right there. If you have the marinara sauce with the pasta, you have salt there. So you realize that there are so many different ways, without you choosing items that we might clearly associate with a high sodium content, that there are a lot of places that we’re all consuming salt.”

Bibbins-Domingo supports efforts like the one in New York City. There Mayor Michael Bloomburg is urging food manufacturers to reduce the salt in their foods by 25% over the next five years.

Mark Kurlansky thinks it’s a terrible idea. He wrote a book called “Salt.” When laws curb smoking – that’s one thing. But salt is something different:

“You have to deal with the fact that people like salt. There isn’t the moral imperative of cigarettes because there isn’t a problem of second hand salt. If you don’t want to eat salt and the guy at the next table wants to eat it, it’s not going to affect you. It becomes an issue of government messing around with individual choice.”

But most people don’t realize they’re making that choice – there’s just so much salt in all the foods they buy. Other countries, such Finland and England, have worked with food manufacturers to lower salt content. In the UK, they cut sodium in foods by 10-percent. And researchers say the public didn’t even notice. They’re still studying to see if it’s actually improved health.

If you read nutrition labels on food packages, you might be surprised by how much sodium there is in a lot of foods.
Some researchers say all that salt is causing a plethora of health problems – and they want the government to force food manufacturers to lower the salt content. Julie Grant reports.

When Dr. Kirsten Bibbins-Domingo sees patients with high blood pressure, she advises them to cut back the on the salt.

She says they often return to the office – happy to announce that they’ve cut out fast food and processed snacks.

“AND THEN I ASK THEM TO TELL ME WHAT THEY’RE EATING AND I AM AWAYS BLOWN AWAY WHEN THEY COME BACK WITH THESE NICE HEALTHY VEGETABLE SOUPS THAT ARE CHOCKED FULL OF SALT. AND SO ALL THE THINGS THAT THEY DON’T REALIZE ARE HIGH IN SALT ARE ACTUALLY STILL THERE IN THEIR DIET.”

Bibbins Domingo is associate professor of medicine and epidemiology at the University of California in San Francisco. She’s also lead author of a recent study published in the New England Journal of Medicine.

Researchers at Stanford and Columbia University Medical Centers co-authored the study.

They did a computer simulation – to see what would happen if every American reduced their salt intake by a half teaspoon a day. That’s 3 grams.

“WHAT WE FOUND THAT IS IF WE WERE ABLE TO REDUCE SALT IN THE U-S DIET BY 3 GRAMS PER DAY, WE WOULD ANTICIPATE 100-THOUSAND FEWER DEATHS EACH YEAR, 100-THOUSAND FEWER HEART ATTACKS, AND MORE THAN 100-THOUSAND FEWER CASES OF NEW HEART DISEASE.”

Bibbins-Domingo says the health savings of reducing salt are comparable to cutting the number of smokers in half.

But not everybody puts that much stock in the new study.

Michael Alderman is a professor of medicine and epidemiology at the Albert Einstein College of Medicine. He says the government shouldn’t act so quickly based on this new study:

“WELL, IT’S INTERESTING THAT IT’S CALLED A STUDY, WHICH I THINK SORT OF SUGGESTS THAT THERE ARE REAL OUTCOMES AND REAL PEOPLE THAT WERE STUDIED. IN FACT, OF COURSE, WHAT IT IS A SIMULATION, A MATHEMATICAL MODELING.”

Alderman says there are lots of different findings when it comes to sodium consumption. And some show reducing salt intake could have actually have negative health effects:

“WE KNOW THAT REDUCING SODIUM INTAKE, BY AN AMOUNT SUFFICIENT TO REDUCE BLOOD PRESSURE, ALSO INCREASES SYMPATHETIC NERVE ACTIVITY, IT INCREASES RESISTANCE TO INSULIN…”

If we already ate low salt diets, the researchers in this latest salt study say those concerns might be valid. But Dr. Bibbins-Domingo says salt consumption in the U.S. is higher than is recommended, and it’s on the rise.

But she says there are high levels of salt in so many foods, it’s hard to avoid. Cereal. Bread. Lunch meat. Pasta Sauce.

And she says consumers can’t really reduce salt consumption without some changes by food manufacturers.

“RIGHT NOW THERE ARE NO CHOICES THAT ARE REALLY AVAILABLE THAT MIGHT BE LOWER IN SALT. I THINK THAT’S WHERE THE EFFORTS WITH THE FOOD MANUFACTURERS ARE ABOUT REALLY MAKING A RANGE OF CHOICES SO WE CAN EAT LOWER SALT, WHICH IS VIRTUALLY IMPOSSIBLE RIGHT NOW.”

Some governments are responding. New York City has already started urging food manufacturers and restaurant chains to lower the salt in their foods by 25-percent over the next five years. Bibbins-Domingo says California is considering salt limits in foods the state buys for schools, prisons and other public institutions.

She also wants the Food and Drug Administration to require food makers to alert consumers when foods are high in salt.

In the meantime, Bibbins-Domingo advises her patients to look at food labels – and really look at the sodium content – so they know what they’re getting.

New Houses Get a Little Smaller

  • Huge houses are on the decline. (Photo courtesy of Brendel Signature)

The American dream of home ownership has become a trend of bigger and bigger houses. The square footage of new, detached houses crept upwards for decades even though families shrank. Recent economic troubles have stopped the big house trend. Shawn Allee reports:

Transcript

You might not know it but the American dream of home ownership has translated into bigger and bigger houses.

The square footage of new, detached houses crept upward for decades, even though families shrank.
Shawn Allee reports recent economic troubles have stopped the big-house trend.

Housing stats kinda say it all.

Just after World War II, brand new single-family detached homes were about 1100 square feet.
By 2007, they were twice as big.
One builder, Andrew Konovodoff, says 2007 was the peak.

Konovodoff: My analogy is, you go to McDonalds, you can up-charge or supersize your meal and get a couple hundred extra french fries.

Alee: People did that with homes?

Konovodoff: Yeah. Money was available. People bought more home than they needed. Now, I think people have trended back the other way.

Konovodoff’s right.
The U-S Census bureau says brand-new homes shrank for two years straight, and home builders say they’re going to build smaller for at least another year.

That hasn’t happened in decades, and builders like Konovodoff are adjusting

In the smaller square footages you won’t see a formal dining room … you’ll have an eat-in kitchen. We’ve pushed out the formal dining room.

Konovodoff says he’s considering even smaller designs.
He says it’ll be trickier to make a good living, so he’s not exactly happy with the trend.
But there are people who are glad houses are getting smaller.

One of them’s Alex Wilson.
He edits a magazine called Environmental Building News.

Wilson: In building a house, we need lumber, new windows and a whole range of building materials. It’s just common sense that a smaller house will use less materials. Even with any material, a so-called green material made from recycled content, there’re still impacts from manufacturing that product and shipping it to the job site. So, when we use less, we reduce environmental impact.

Wilson says the size of new homes has dropped just a bit … maybe the equivalent of a big closet or a tiny, tiny dining room.

He’d like homes to see homes get even smaller, but that won’t happen until our heating and cooling bills jump higher.

Wilson: I think if we were paying five dollars a gallon for gasoline and equivalent prices for natural gas and heating oil, then we would see a much more dramatic drop in house size.

Wilson says most of us won’t demand or build small houses until we truly fear a life-time of high utility bills.

DRAWING UP AN ENERGY EFFICIENT MORTGAGE (Short Version)

As homeowners face another winter of rising heating bills, one loan officer in the
region
is promoting energy efficiency when people shop for a mortgage. The Great Lakes Radio
Consortium’s Erin Toner reports:


The government and government-chartered companies such as Fannie Mae offer Energy
Efficient Mortgages. But relatively few homeowners take advantage of them. Under the
program, new or existing homes are inspected and rated for energy efficiency. The
homeowners decide which energy-efficient improvements to do, and then roll the cost of
them into their mortgage.


Joel Wiese is a loan officer. He recently closed one of the few non-governmental
energy
efficient mortgages in the Great Lakes region.


“When you start looking at the total housing expense, utilities on top of the rest
of what
you’re doing, you’re basically going to spend less money than you normally would.
Because you’re reducing your utilities. Even though you’re increasing your mortgage
slightly, you’re reducing your utilities significantly. It’s a win-win.”


Wiese says there haven’t been more energy efficient mortgages in the region because
few
realtors, loan officers and lenders know how to use the program.

Solution for Arsenic in Drinking Water?

  • Researchers from the University of Illinois have discovered a way to remove arsenic from drinking water at its source. (photo by David Guglielmo)

arsenic levels in drinking water. They say, for people to drink water from wells or aquifers, the solution starts at the source. The Great Lakes Radio Consortium’s Jeff Bossert explains:

Researchers believe they have found a way to reduce arsenic levels in drinking water. They say, for people to drink water from wells or aquifers, the solution starts at the source. The Great Lakes Radio Consortium’s Jeff Bossert explains:


Chronic exposure to arsenic in drinking water has been linked to a variety of health concerns, including hypertension, cardiovascular disease, and cancer.


Researchers from the University of Illinois collected groundwater samples from 21 wells. They found that the wells with almost no arsenic in the water also contained high levels of sulphate-reducing bacteria, which convert the arsenic into a solid, where it drops out of the water. Dr. Craig Bethke led the study.


“What we’re saying is that if there’s sulfate in the water, then there’s probably sulfate-reducing bacteria active in the subsurface, and that means that a simple field test, which is very inexpensive and very rapid to protect sulfate, could identify safe water sources.”


Bethke says places where aresenic levels are high, sulphate salts, such as gypsum and calcium sulphate, can be injected underground to reduce arsenic levels.


Researchers say this information could prove to be invaluable in places where aresenic contamination is a major problem, including parts of the U.S., Australia, and Mongolia. The researchers’ findings were published in the journal Geology.

Seeking Answers to Spring Sewage Dumpings

One of the biggest dumpers of raw sewage into the Great Lakes this year may be heading toward a solution that puts the cleanup burden on local citizens. The Great Lakes Radio Consortium’s Chuck Quirmbach explains:

Transcript

One of the biggest dumpers of raw sewage into the Great Lakes this year may be heading toward a solution that puts the clean-up burden on local citizens. The Great Lakes Radio Consortium’s Chuck Quirmbach reports:


Several cities dumped sewage into the Great Lakes during heavy rains this spring and summer. Milwaukee’s overflow total was about five billion gallons. A task force set up by Milwaukee’s mayor concludes much of the problem came from rainwater leaking into the sewer system through illegal hookups and cracked pipes between homes and sewer mains. Mayor Tom Barrett says reducing the so-called infiltration and inflow, or, I and I, will be expensive.


“Well, we’re obviously going to have to put more dollars into I and I in Milwaukee. The city has done that, we’re doing more in this budget, we’re going to continue to do more… I think each of the communities is going to have to face that issue.”


The “communities” are the roughly 30 smaller cities that use the Milwaukee sewer system. Wisconsin’s attorney general is trying to ge the city and suburbs to work together. Milwaukee and many other Great Lakes cities are also asking the U.S. government to spend more money on reducing sewer overflows.
