Some people are worried that
lots of plug-in electric cars
will cause brownouts or blackouts.
At least two automakers will have
plug-in electrics on the market
next year. But utility companies
say, don’t worry. They’re ready.
Tracy Samilton reports:

A lot of electric power plants in the U.S. sit idle between 9 p.m. and noon
each day.

Ed Kjear is head of Electric Transportation for Southern
California Edison. He says, as long as people plug in their electric cars
during those off-peak hours.

“160, 170 million cars could connect
to the grid tomorrow
and we wouldn’t have to build new power plants to meet that load.”

At first, just a few thousand people will own plug-in electric cars at
first. Utilities will work with these customers to hook up to new “smart
grid” technology that can program when each car starts recharging.

“The customer will say, ‘look I need
the car fueled by
6 or 7 tomorrow morning. You know, have at it.'”

Kjear says the technology will be easy to install and use by the time most
of us shift from gasoline to electricity to fuel our cars.

That search for the right cell phone charger should soon become a thing of the past. Cell phone makers have agreed to come up with a universal adaptor. Julie Grant reports that that could save tons of landfill space:

Top cell phone makers – including Nokia, Samsung and Apple – have struck a deal to standardize handset chargers for European consumers by next year.

And the U.S. wireless industry association says Americans will likely see a universal charger before 2012.

That means when you buy a new phone, you won’t need to buy a new charger. You’ll be able keep using the one-size-fits-all charger.

Ted Scardamalia is with the technology analysis firm Portelligent. He says this is good for consumers – and the environment.

“If I have a charger that lasts for two or three or four phones, that’s two or three or four chargers I don’t have to recycle or put into a landfill.”

Last year, an estimated 1.2 billion cell phones were sold worldwide, according to University of Southern Queensland data reported by industry umbrella group GSMA (Groupe Speciale Mobile Association), generating up to 82,000 tonnes of chargers.

With concerns over the level of waste generated by redundant or outmoded chargers, European legislators had, prior to Monday’s agreement, considered forcing manufacturers to adopt universal technology.

Is There Hope for Hydrogen?

Researchers and start-up companies are looking for new ways to power the country. There’s been a lot of hope for hydrogen. But as Mark Brush reports there have been some bumps for companies on the road to the new hydrogen economy:

There has been a lot of excitement about hydrogen fuel cells for awhile now.

Ten years ago we talked to a rep at a company called Plug Power. He was excited about selling a dishwasher-sized fuel cells that could power and heat your home.

“The only barrier to fuel cells is that people don’t know about them.”

Turns out, that wasn’t the only barrier.

It’s expensive to make these things, and the units weren’t as efficient at heating as they hoped they would be.

But the company is still around, and they are still hopeful about fuel cells for your home.

Andy Marsh is the president of Plug Power.

“So the industry hasn’t moved ahead as rapidly as we would like. It sometimes takes many more years to makes some progress than you had originally hoped.”

Marsh says his company is selling fuel cells in places like India, but he says fuel cells for our homes in the US are probably still three to five years away.

Car makers are showing off new

hybrids. Foreign manufacturers have a

Toyota has been doing well with its hybrid,
the Prius, and the Japanese company plans

Lester Graham talked with Julie Halpert.
She’s a reporter who’s been covering the
preview of the Detroit Auto Show (opens
Saturday January 17th). She says
Honda, which started this hybrid trend,
hasn’t done much lately, but it is now:

Lester Graham: They’re paying a lot of attention to the Detroit Auto Show this
year because of the bailout and because of the new green cars that are being
displayed. Julie Halpert’s been covering the Auto Show. Julie, there’s a lot of
talk about the domestic automakers bringing on board hybrids and plug-in
hybrids in the near future, but it appears the Japanese automakers are coming
out ahead.

Julie Halpert: What’s interesting is the Japanese automakers feel it’s more
important in the near future to focus on regular hybrids. For example, Honda is
coming out with a new version of its Insight, that is comparable in size to the
Prius. And, it’s going to be the most affordable Hybrid. Priced under $20,000,
which makes it very attractive. Their argument is, these electric cars are
interesting, but there’s a lot of work to be done on the battery, and, so they would
rather see lots of people in hybrids, near-term. They think that’s going to make a
bigger difference environmentally than coming up with these plug-in hybrids,
which are going to be more expensive, and aren’t going to be offered for the next
couple of years.

Graham: If oil prices stay low, I’m wondering if domestic automakers will stay the
course of these more energy efficient cars. It sounds like they want the
government to force consumers into that market.

Halpert: Well, the government’s obviously placing a priority on this. And what
they’re very much hoping is that the government fuels demand by creating tax
incentives for these vehicles – they have the ability to do that, Congress has the
ability to do that. I think they’ve invested so much now, there’s really no
reversing course. The problem is that customers are very fickle. If gas prices
are low, they’re going to go back to their conventional internal combustion
engines. When gas prices were high, this past summer, there was a huge cry for
these alternative, more fuel efficient vehicles. The problem is that automakers
need to plan months and months in advance to bring out these vehicles. So
now, they’re on course to do that, it would be very difficult for them to switch
course at this point.

Graham: While Honda’s coming out with this new version of the Insight, Toyota’s
coming out with a third generation of the Prius, GM’s trumpeting the Volt, Ford is
going after smaller engines with turbo power. Why are they taking that
approach?

Halpert: Well, it’s actually quite a prudent approach. They’ve got this hybrid
Ford Fusion, which gets 41 miles per gallon. And, they’ve got this super turbo-
charged engine, which can boost fuel efficiency by 20-30%. And, their argument
is, let’s use more conventional motors to do this, because it gets into an
affordability issue. They can basically provide the power of a V8 engine in a V6
engine. And, consumers still want that power. They want low costs. So, they
figure, this new technology can go quite far in getting a lot of fuel efficiency and
not requiring consumers to pay this up-front premium that other hybrids cost.

Graham: That’s Julie Halpert, who’s been covering the Detroit Auto Show.
Thanks, Julie.

Halpert: Thank you so much.

Detroit Gets Electric

Car makers are at the North
American International Auto Show in
Detroit to show-off their hybrids,
and coming plug-in hybrids. Lester
Graham reports:

GM, Ford and Chrysler have all built hybrids and have plans for more – and all plan
plug-in hybrids. Those kinds of cars need good batteries.

Soon lithium ion batteries will replace what’s being used now. But, it’ll still only get
you 40 miles at best in plug ins before it runs out of juice and needs the gas-powered
engine onboard.

So making even better batteries is important to GM, Chrysler and Ford’s Executive
Chairman Bill Ford.

“I actually think the battery break-throughs will now start coming relatively quickly.”

But what if gasoline prices stay low? Will the majority of car buyers care about fuel
efficiency?

GM’s Rick Wagoner bets as the economy improves, gas prices will go back up.

“In general we’d expect oil prices to resume an increase. Hopefully a more gradual
one than we saw last year.”

And the automakers hope the government continues to encourage sales of fuel
efficient cars with tax credits.

Part One: Kicking Gas to the Curb

people make a typical commute without the gas engine. Carmakers and the government are throwing a lot of money at the technology – GM and Chrysler both hope to release models in the next few years.

One of the great hopes for a green
car is the plug-in hybrid. It’s like a regular

people make a typical commute without the gas
engine. Carmakers and the government are
throwing a lot of money at the technology – GM
and Chrysler both hope to release models in the
next few years. But the cars might not deliver
what boosters promise. In the first part of
our series on saving gas, Gabriel Spitzer
reports on what new research says about plug-in
hybrids in the real world:

Ted Bohn is a researcher at Argonne National Laboratory in the Chicago
suburbs and he’s showing off his ride.

“So this a prototype, plug-in hybrid vehicle. The rear half is a 10
kilowatt-hour battery.”

It’s a modified Saturn Vue, with a big old lithium-ion battery in the rear.

That battery is like what runs your iPod – only it weighs as much as a
linebacker.

Ted Bohn: “If you actually had to drive less than 40 miles on a typical
day, you could drive the whole day without starting the engine.”

Gabriel Spitzer: “Could you drive this very vehicle 40 miles round-trip
without starting the engine?”

Ted Bohn: “Close. If you drive slowly. To be honest, 25 to 30 is what
you’ll really do – driving on a nice day downhill with a tailwind is 40,
more realistically, 25 to 30.”

The thing is, you don’t hear those little caveats from some people, like, say,
General Motors.

“You plug it in. And they expect you’ll get up to 40 miles without a drop
of gas. Wow. The Chevy Volt. I’ve heard the future, and it hums.”

That 40-mile range is based on EPA tests.

Argonne scientist Aymeric Rousseau, with backing from the government,
compared those measures to how people drive in the real world.

Based on more than 100 drivers in Kansas City, he found that 40 mile range
shrinks to about 30.

Flip on your AC, and it’s more like 20.

“People now think about, you know, your mileage may vary. Now we
have to think about, your electrical distance may vary, depending on
how you drive, and what accessories you’re using.”

Rousseau says factors like aggressive driving sap the all-electric range.

And don’t forget – we’re talking Kansas City, here.

“When we talk to people from the EPA they actually say that people in
California drive more aggressively than people in Kansas City.”

General Motors concedes the point.

Rob Peterson is a spokesman for GM.

He says driver behavior can have some affect on the all-electric range.
Though …

“I wouldn’t go as low as 28 to 32.”

He says for a reasonable driver, the Volt can still get about 40.

And how about those pedal-to-the-metal Californians? Well, he says GM
studied exactly those people.

“For 64% of the people that we tested, they would be able to finish their
day with a petroleum-free and a tailpipe-emission-free commute.”

That’s not exactly what Argonne found.

Granted, the batteries they looked at were a little smaller than the Volt’s.
Size matters when it comes to batteries.

Said Al-Hallaj teaches at the Illinois Institute of Technology.

He says carmakers could build a battery that would boost up the all-electric
range – the problem is money.

“If you’re talking about a 25% increase, you know, from 30 to 40 miles,
that could mean thousands of dollars. So that could take it out of the
price range that will make it actually practical for the industry to make
it.”

Al-Hallaj says as the technology improves, so will drivers.

People are already getting better at squeezing fuel efficiency out of their
cars.

“For the first time I see people even worried about closing the window
versus opening the window because of drag. And we’re talking about
common people here, just trying to pay attention to, if your tires are not
properly inflated, the you have prob — so people start adapt and
probably get the best out of your battery.”

So it’s not that a plug-in hybrid can’t get 40, it’s just that you need to drive
like a grandmother to do it.

But if gas prices continue to climb, we may be seeing a lot more grannies
behind the wheel.

Power Plant Pollution From Plug-Ins?

The big automakers are working on
coming up with plug in hybrids. By the
end of 2010, G-M and Toyota plan to have
cars you can plug in to charge up batteries,
backed up with small gas powered engines.
Lester Graham reports there are concerns
about whether pollution from power plants
will be any better than pollution from tailpipes:


I was out the other day with a guy who converted his Saturn four-door into an all electric
vehicle. Did it all himself.

His name’s Bob Gurk. He’s one of a lot of people who think there’s a better way, and
they want you to see for yourself.

Bob Gurk: “Here are the keys.”

Lester Graham: “I’m drivin’?”

Guys like Bob Gurk think the big automakers should have come up with electrics and
plug-in hybrids a long time ago.

Lester Graham: “Unplug here?”

Bob Gurk: “Yeah.”

(sounds of driving)

Bob Gurk says, sure, he spent a lot converting his car to electric. And there are some
sacrifices: no air conditioning, he can only go just a little over 50 miles without a charge,
but then, he’s not paying close to four-bucks a gallon for gasoline now.

Bob Gurk: “I figure it’s about three cents a mile.”

Lester Graham: “Three cents a mile?”

Bob Gurk: “Yeah.”

Lester Graham: “As opposed to gasoline, which is?”

Bob Gurk: “Ten cents a mile, I’d say. At least.”

Some people get a little concerned about more electrics and electric-hybrids. That’s
because 50% of electric power in the U.S. comes from coal-burning power plants. And,
just about every state wants to build more power plants to meet peak demand.

A guy who’s supposed to know something about electric cars is Andy Frank. He’s at
the University of California Davis. Some call him the father of the plug-in-hybrid. Andy
Frank says we don’t use all the power that’s available right now.

“What a lot of people don’t realize is that the grid actually has excess capacity. The
reason why is there has to be enough capacity to satisfy the peak draw in the middle of
the day. But, at night everybody turns off their lights and that draw goes down to about
anywhere between a half and two-thirds of what is required during the peak of the day.”

So, the idea is you could plug in your plug-in hybrid overnight.

“And then the question is how many cars could you charge with that idle capacity on our
existing grid? About 75 to 80% of cars in our entire fleet in the U.S. could be charged
with that excess capacity that we currently have.”

That’s assuming most people would only plug in at night, during the off-peak hours. If
most of them did, that would be a lot of cars that would not be emitting pollution from the
tailpipes.

But that also means some power plants will be burning more coal at night, billowing out
pollution, including greenhouse gasses.

Dustin Dwyer reports on automotive issues for Michigan Radio and he’s covered this
issue.

“One of the benefits, the power companies will tell you, is that if you have millions of
tailpipes out there spewing emissions, it’s much more difficult to capture those emissions
or manage those emissions than it is to manage coming out of one smokestack at the
power plant.”

But, you do end up shifting some pollution upstream to the power plants. And that
would pollute rural areas more, because that’s where they build the power plants.

The experts say that’s why we ought to start building parking lots with car ports covered
in solar panels, put up more wind turbines, and find other ways to use energy better – to
power all those electric and plug-in hybrids that are coming.

For The Environment Report, this is Lester Graham.

The federal government and US carmakers are spending more

money on battery research for plug-in hybrid vehicles. That’s because

existing battery technology is limited. But some of the grant winners

say success won’t come easily. Chuck Quirmbach reports:

The US Advanced Battery Consortium is made up of General Motors, Chrysler and Ford.
Together with money from the Department of Energy, the consortium is handing out millions of
dollars to develop batteries for Hybrid vehicles.

Johnson Controls and a partner will develop lithium-ion batteries for plug-in hybrids.

Michael Andrew is a spokesman for Johnson Controls. He says his company has a lot of work to
do to make a battery that will go forty miles between charges.

“You’ve got to hit volume targets, weight targets, power targets, energy targets, cost targets. For
the 40 mile range application, that’s gonna be a tremendous challenge for us.”

The battery and car makers say it might take even more government support to help the US auto
industry shift away from gasoline-powered cars.

Critics say the companies should have focused sooner on fuel efficiency.

Reducing Ground Level Ozone Pollution

  • Russ Adams mows his lawn with an electric lawnmower. He does so to reduce local air pollution such as ozone. (Photo by Christina Shockley)

Summer can be a perfect time for barbeques, weekend trips, and yard work. But those very things contribute to a summertime health hazard. The Great Lakes Radio Consortium’s Christina Shockley reports:

Transcript

Summer can be a perfect time for barbeques, weekend trips, and yard
work. But those very things contribute to a summertime health hazard. The
Great Lakes Radio Consortium’s Christina Shockley reports:


(sound of gasoline-powered lawn mower)


This time of year, it takes just a short walk along pretty much any residential
street to find someone mowing their lawn.


(crossfade, gas-powered lawn mower sound out, electric mower sound up)


But if you walk past the Minneapolis home of Russ Adams, you might take a
second look.


“My neighbors came over… they were a little bashful ’cause they
weren’t sure how to pose the question. But they wanted to know what I was
doing in my yard and what that machine was. They thought it was some kind of
new-fangled mulcher or something.”


That mulcher is actually an electric lawnmower. The mower is a sleek red and
black. It’s about the same size as a gasoline mower. There’s no cord running
to it. It runs on a battery. There’s a plug on the back of the main unit
that’s used to charge it.


(sound of garage door opening)


“Okay, so this is the garage. Just plug it in
right here, and really it doesn’t take long for it to juice up. And you just
leave it plugged in, and as soon as it’s fully charged it stops drawing on the
electricity, so it’s energy-efficient even in the recharging mode.”


Adams says the main reason he uses the electric mower is that it’s just one way
he can help improve air quality in his city. And as small a step as that
seems, emissions from small engines such as lawnmowers do cause air quality
problems.


Rebecca Helgesen is with the Minnesota Pollution Control Agency. She says one
major summertime problem is ozone. Helgesen says human activity creates the
ingredients in ozone.


“Certainly motor vehicle exhaust and chemical solvents are major
sources. Also, industrial emissions and gasoline vapors.”


The chemicals stew and combine with hot, humid conditions to increase ground
level ozone.


“When the air is stagnant – not moving very much, and it’s hot and
sunny, that’s when you see the chemical reaction that creates ozone.


Helgesen says the Environmental Protection Agency forecasts ozone, so people
will know ahead of time when not to mow their lawns or to stay indoors. The
forecast is called an Air Quality Index. It uses color codes. On a “yellow”
day, the air is dangerous for sensitive people. On a “red” day, everyone is
encouraged to limit outdoor activity. Ground level ozone can cause lung
damage. Helgesen says breathing ozone isn’t good for anyone, especially those
with asthma.


“You’re coughing more, you may find you have some tightness in your
chest, or uncomfortable. You may find that you’re tired more easily.. all of
those mean that there has been some compromising of your lungs.”


Ozone levels start to fall in the evening as people stop driving, as the sun
sets and the air cools. Helgesen says the Minnesota Pollution Control Agency
encourages people to wait to pump gas, drive, and mow their lawns until 7 or 8
at night.


Getting people to do these things is where the organization, Clean Air
Minnesota, comes in. Its members include an unusual mix of business groups,
environmental groups and others.


Bill Droessler is the group’s program director. He says Minneapolis-St. Paul doesn’t
have a big ozone problem, like some other cities… yet. Clean Air Minnesota wants to keep it that
way. If levels go up, the federal government could impose restrictive – and
costly – regulations. Droessler says his group holds on-site training programs
at participating businesses to get people to take action.


“Postpone landscaping things, use of internal combustion engines as late as
possible on those days. Avoiding backyard recreational fires.”


He says even using newer gas cans that don’t let vapors escape as easily helps
reduce ozone. Droessler says he hopes people will take the time to make just one change to
help reduce ozone levels.


Russ Adams sees his electric mower as his one small action. He concedes that
the electric mower does use electricity. But while coal-burning power plants
do pollute, his electric mower is better for air quality than a gas-powered
mower.


“My argument is that if everybody had an electric mower, then we’d be cutting
down on the air quality problem. Wouldn’t solve it, but we’d be making a good dent.
I mean, I talk to my friends all the time about how fun it is to use this
mower.”


Shockley: “So I press it down… and pull back…”
Adams: “There you go.”
Shockley: “Oh, it’s very easy!”


(sound of electric mower)


Adams: “Now what I want you to do, is do this part of the yard in the back. I’ll go in and
have some tea, maybe some orange juice, and then we can tackle the front yard
after you’re done back here.”


Shockley: “Okay, that sounds great.” (laughter)
