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.

Automakers Push a Gas Tax

  • These Suzukis at Ken Butman's dealership, which were in high demand last year, are now sitting unsold (Photo by Samara Freemark)

Chances are, you haven’t bought a new car this year. Auto sales are down across the board – including in the small car and electric-gas hybrid markets. Now some dealers and automakers are proposing a way to move some of those cars: increase the gas tax. Samara Freemark explains why the same people who sell cars might want to make driving them more expensive:

Chances are, you haven’t bought a new car this year. Auto sales are down across the board – including in the small car and electric-gas hybrid markets. Now some dealers and automakers are proposing a way to move some of those cars: increase the gas tax. Samara Freemark explains why the same people who sell cars might want to make driving them more expensive:

It was almost exactly this time last year that Ford dealer Ken Butman
traded in his pickup for a Suzuki hatchback.

His Ann Arbor, Michigan
dealership had been selling Suzukis for a couple of years. But they got
really popular last spring when gas prices jumped. Butman ordered a big
shipment to keep up with the demand.

“These are the Suzukis. These little cars get good gas mileage. And
they’re so cute. Look at them. Look at this one here. It’s got a little
rack for your skis. Look at
that.”

But those cars – the ones Butman ordered a year ago – most of them are
still here. They’re still sitting on his lot. Not moving.

“It was strange because they were so hot. For awhile there you couldn’t
give a big car away. And everybody was rushing to the small cars. And then
just as quickly, about when the price of gas came down again, we saw a
complete reversal. Like a light switch. That’s how fast it cut off.”

It’s been like that all over the country. Dealers who last year had
waiting lists for hybrids and small cars suddenly have a lot of extra
inventory. Sales of hybrids are way down from last April, mostly because
gas costs about half what it did last year.

Brett Smith is an auto analyst with the Center for Automotive Research. He
says consumers only really care about fuel economy when gas prices are
high. When gas hits about 4 dollars a gallon, consumers switch to fuel
efficient cars. When prices drop again, so do sales of efficient cars.

“Look at what’s happened every time we’ve had an energy crisis. We’ve
gone to smaller cars for a couple of years, and then the consumer has gone
back to larger cars. Why? Because at that fuel price they can get away with
it, they can justify it.”

It’s a real problem for dealers. It also worries auto manufacturers who
have poured money into developing hybrids and have a lot of new models due
to come out this year.

And that’s why some people who sell cars have begun to push for
increasing the gas tax.

Dealers and auto executives might not seem like the first bunch to line up
behind a tax hike. Traditionally they’ve lobbied hard against anything
that makes driving more expensive.

But a high tax – and therefore, higher gas prices – could get all those extra
hybrids moving again.

Michael Jackson is the CEO at AutoNation. That’s the
nation’s largest chain of dealership.

Jackson wants to see gas at four
dollars a gallon – the figure at which many analysts say consumer behavior
changes. And he thinks the government can keep prices at that magic number
with a floating tax.

Auto makers have been a little more cautious. But some top executives at
American companies have called Jackson’s ideas ‘smart’ and ‘worth
looking into’.

Smith says they believe that higher gas taxes could
stabilize the market for fuel efficient cars – making investment in new
technologies a safer bet.

“The car companies will rarely come out and loudly say, things like, ‘we
think there needs to be a gas tax.’ But almost all of them will say on the
side, if you want people to drive more fuel efficient cars, the best way to
do it is a gas tax.”

For now, though, it might not take a big tax to bring gas prices back up.

Oil trader Anthony Grisanti is the president of GRZ Energy. He says an
economic recovery would do pretty much the same thing.

“Shouldn’t be any doubt about it, once the economy picks up, say,
beginning of next year or year after that, you’re going to start to see oil
prices go higher.”

And that means prices at the pump would go up too.

Proposing higher gas taxes – especially of a couple of dollars a gallon – can
mean career suicide for politicians. So a big hike in the gas tax seems
iffy. But if gas prices rise as the economy recovers, dealers might see
those fuel efficient cars move off the lot again.

Private Wells Tainted

A new report finds that almost one quarter of the private wells in the country are contaminated. Mark Brush reports on a new study that tested the quality of well water:

Transcript

A new report finds that almost one quarter of the private wells in the country are contaminated. Mark Brush reports on a new study that tested the quality of well water:

The government sampled wells across the country. And it found that twenty-three percent of the private wells tested had chemicals at levels that could cause health problems.

The United States Geological Survey published the report. Bob Gilliom is one of the authors.

He says most of the contaminants they found came from natural sources underground – such as arsenic – which is a poison:

“So certain parts of the country there was a relatively high incidence of arsenic concentrations that were greater than the maximum contaminant level identified in the Safe Water Drinking Act.”

Man-made chemicals were also found – especially near farms where nitrogen fertilizers are used. Around one quarter of all the wells tested in these areas had levels of nitrates considered to be unsafe. In the U-S – about 43 million people get their water from a well. And the government says it’s often up to the home owner to find out whether their water is safe.

Investing in Cars of the Future

  • Both studies agree that we need more efficient cars (Photo by Karen Kelly)

Recently two reports on the future of automobiles came out. They looked at cars and trucks from very different perspectives, but came to some similar conclusions. Lester Graham reports:

Transcript

Recently two reports on the future of automobiles came out. They looked at cars and trucks from very different perspectives, but came to some similar conclusions. Lester Graham reports:

The first report was published in the journal, Environmental Science and Technology. It looked at what it would take to get U.S. automobiles to reduce the greenhouse gas, carbon dioxide, enough to lower it to 1990 levels.

Why cars? Because cars and trucks produce a third of U.S. CO2 emissions.

Greg Keoleian is one of the authors at the University of Michigan. He says there are three things that need work.

We need to drive less, burn cleaner fuels, and, within about 40 years, increase the average fuel mileage way beyond the 20-miles per gallon we’re getting now.

“That would need to increase to 136 miles per gallon to meet the carbon targets. Alternatively, if we just focused on fuels, basically we’d need about 80% cellulosic ethanol by 2050. And the third scenario is a reduction in driving. It would mean we’d have to cut our driving in half by 2050.”

It’s unlikely we can accomplish any one of them, and the study’s authors suggest it’ll probably be a combination of more efficient cars, better fuels, and driving less if we’re to reduce greenhouse gases enough to make a difference.

The second report entitled ‘Envisioning an Uncertain Future’ comes from the Boston Consulting Group. It looks at the future of the automobile from a business perspective.

One of the authors, Xavier Mosquet, says the study assumes rising oil prices will force some changes.

“And that the pressure from the consumer on the governments will be so high that the governments will have to take energy actions to develop green products and green cars.”

But the report notes green cars will cost more – as much as 15,000 dollars more for hybrids or plug-in hybrids compared to standard cars.

“The consumer will look at these cars and say, ‘well, these are more expensive than I can pay.’ And therefore they’re not going to buy them. So, what I think the government has to do if they want to go that way is to look at the cost of putting those technologies on the market and either subsidizing the car’s manufacturers and suppliers or helping the consumer with much more tax incentives. Otherwise it will not happen.”

So, from a business perspective, the Boston Consulting Group report suggests without government help, manufacturers won’t build more efficient cars at a price we can afford. But we’ll need them because of high fuel prices.

The University of Michigan report on cars and climate change agrees the government will have a major role.

Author Greg Keoleian says if we take climate change seriously and are committed to doing something about it, we’ll have to change driving habits, encourage innovative manufacturers and invest government money.

“We are capable of doing this and the cost of climate change to society is tremendous. And each sector needs to play a major role in addressing the needs to reduce.”

The studies look at the future of the automobile from very different perspectives, but both agree we need more efficient cars and that won’t happen without the government pushing a little and helping a lot.

Nyc to Turn Yellow Cabs Green?

  • NYC has new incentives to try to get more hybrid taxis, like this one, on the road (Source: Momos at Wikimedia Commons)

When big cities think about putting more fuel efficient, less polluting cars on the road, the first color that comes to mind isn’t green — it’s yellow. There are so many cabs on city streets, they seem like a good place to start environmental initiatives:

Transcript

When big cities think about putting more fuel efficient, less-polluting cars on the road, the first color that comes to mind isn’t green— it’s yellow. There are so many cabs on city streets, they seem like a good place to start environmental initiatives. In New York City, the mayor has a plan to replace conventional cabs with gas-electric hybrids. But not all taxi drivers are thrilled about the plan. Samara Freemark talked to some of them:

Ask a New York city cabbie what kind of car he drives, and chances are, this is what you’ll hear.

“Crown Vic.”

“Crown Vic.”

“Crown Vic.”

Cabbies love this car. It’s this big, solid, safe thing. It’s got a lot of leg room. It’s easy to repair.

But it burns a lot of gas. And that means a lot of pollution, especially when you realize that there are 13,000 cabs in New York City. All that pollution contributes to asthma, heart disease, and a mess of other health problems.

And that is why New York mayor Mike Bloomberg has it in for the Crown Victoria.

Bloomberg has a plan. He wants to use market incentives to encourage cab companies to buy hybrid.

“To turn NY City’s yellow cabs green.”

Cute slogan.

But Bloomberg isn’t messing around. Just ask the reporter who challenged the idea at a press conference.

“The taxi owners who oppose your plan say it’s deeply troubling that the city is…”

“I think it is more deeply troubling that they’re trying to kill our kids.”

Tough talk, right? But here’s how Bloomberg’s plan would actually work.

A lot of cabbies don’t own their own cars – they lease them from cab companies.

Bloomberg wants to lower the fee companies can charge drivers to take out Crown Victorias. So company owners would make less money on conventional cars.

And he wants to let cab companies charge drivers more to take out hybrids. Companies that chose those cars would make more money, giving them a reason to go green.

There’s something in it for the drivers, too. Although have to pay more to rent the hybrid cabs, they’d make up that money, and then some – a big chunk, actually – in gas savings. Bloomberg says hybrid cab drivers could save hundreds of dollars a year under his plan.

It sounded like a win-win-win situation: good for cabbies, good for cab companies, and good for the environment.

So I went out to the curb to ask some cabbies what they thought of the mayor’s idea.

“I wanted to ask you about hybrids.”

“Hybrid taxi? Yes.”

Sukhinder Singh hadn’t heard about Bloomberg’s plan, but he liked it.

“That’s not a bad idea. You’re not spending any extra money. 3, 4 dollars or 10 dollars extra, you know that later on when you go home you get it back because if you spend less on gas. It helps also for the pollution too. Lot of cabs around NYC, so all pollution.”

But a lot of cab drivers – especially veteran drivers – are not that enthusiastic. They are worried that hybrids aren’t safe. They are worried that hybrids are too small. They are worried about the time and money it takes to repair a hybrid. And most of all, cab drivers like Lal Singh are worried about giving up their Crown Victorias.

“Of course we wish not to pay more money for the gas. But I prefer to keep this poor Crown Victoria. This car makes us live. This Crown Victoria is a very big time strong car. These hybrids, they are not for taxi. They are very small, very unsafe, very unfit.”

So you get the idea – he doesn’t like hybrids.

And there’s one more problem with Bloomberg’s plan. It looked pretty good when it came out, when gas was 4 dollars a gallon. But prices now are about half that. That means cabbies don’t save that much money when they pick a hybrid. And so they have even less reason to give up their beloved Crown Vics.

Car makers are showing off new
models at the North American International

are rolling out hybrids and coming plug-in
hybrids. Foreign manufacturers have a
little more experience with hybrids.
Toyota has been doing well with its hybrid,
the Prius, and the Japanese company plans
to release a plug-in version early next year.
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.

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.

Getting Quiet Cars to Make Some Noise

A lot of people who drive gas-electric hybrid cars love how quiet they are. But others say hybrids are so quiet they’re hazardous. People in the blind community say they can’t hear hybrid cars coming… and they’d like to have sound added back into the cars. Rebecca Williams has the story:

A lot of people who drive gas-electric hybrid cars love how quiet they are. But others say hybrids are so quiet they’re hazardous. People in the blind community say they can’t hear hybrid cars coming… and they’d like to have sound added back into the cars. Rebecca Williams has the story:

(tap tap tap of white cane)

Fred Wurtzel has excellent hearing but he can’t see.

He can tell by the echo from his white cane when he’s gotten to the edge of a building or the corner of a city block. And he knows cars by their engines.

(sound of car rumbling past)

“That car has a tweety bird under its hood, a loose belt or whatever it was. Now, there was a car going the other direction. (sound of truck going past) That’s probably a UPS truck.”

But he can’t hear hybrid cars – at least not until they’re right at his feet. That’s because the electric motor is very quiet. And when a hybrid comes to a stop, the engine shuts off.

“If you don’t know there’s a hybrid car there waiting, it may start turning and you may step into its path and not even be aware that there’s a car coming around.”

Wurtzel is president of the Michigan chapter of the National Federation of the Blind. He says the blind community wants some sound added back into hybrid vehicles.

“’Course I grew up in the 60’s so a nice Mustang or something like that would be good (laughs)… just a sound that would let me know that the car’s accelerating or the car’s decelerating – whatever a normal vehicle would sound like.”

Well that’s one idea.

Patrick Nyeste has several ideas. He’s a researcher at North Carolina State University. He tried out 18 different sounds on his test subjects.

Everything from sirens (sound of siren)… to whistles (sound of whistle) … to engine sounds (sound of engine).

“I had a horn from a Beetle – so it’s, ‘meep meep,’ and I would just get giggles from that.”

But, he says to make a quiet car safer, the sound needs to be continuous – like a traditional car. That means some sounds can get annoying really fast.

(sound of continuous beeping)

Yeah that’s enough of that.

Nyeste says that engine noise we heard earlier was one of people’s favorites. They also liked white noise (sound of white noise), and the hum sound (sound of humming). He says that’s because we’re used to hearing those kinds of sounds when a car goes by.

He says a sound added to a hybrid also has to be loud enough to be heard above lawn mowers and garbage trucks.

“You want to make sure that the noise is heard, especially by the blind around corners, around objects, I mean some of these sounds can get masked and that’s important information to know where an object or a vehicle is.”

But some people are worried about adding sound to our cities and suburbs, they say they’re already so noisy.

Lotus Engineering says it has a solution for that. They added a four cylinder engine sound to a Toyota Prius. But the volume’s adjustable.

Colin Peachey is an engineer with Lotus.

“You could set the sound to be higher in certain circumstances or quieter in other circumstances. We could actually make the sound to be whatever level we fancied.”

And you don’t have to hear the sound inside the car.

There’s also a startup company in California – Enhanced Vehicle Acoustics. It’s designing a similar system for hybrids.

But it’s not clear how soon quiet cars might start making noise.

Spokespeople for Toyota and the Big Three say their companies are working on solutions. And some states and members of Congress have been talking about requiring hybrids to make some minimum level of sound.

Then, automakers will have to figure out exactly what a hybrid sounds like.

Csere suggests if the government really wants to change the kinds of cars Detroit
builds, it’ll have to give car buyers a reason to buy more fuel efficient cars.

“If we really wanted to have an energy policy in this country, the solution is not to
force the carmakers to build more efficient vehicles, it’s to force the consumers to
buy them. And a gas tax is a way to achieve that.”

He’s not advocating that policy. And a whole lot of people don’t like the idea – at all.
Members of Congress would rather pressure the troubled automobile manufacturers,
than to tell the voters at home, ‘hey we’re voting to raise taxes on gasoline because
it’s good for the environment.’

Part One: Kicking Gas to the Curb

One of the great hopes for a green

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.
