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.

Pint-Size Cars Sip Energy

Hybrid cars are all the rage nowadays.

But Mike Rhee reports another car could take the concept of green-friendly vehicles a step farther:

These new types of cars are called neighborhood electric vehicles, or N-E-V’s for short.

Now, to me, they look like souped-up golf carts.

But don’t say that to Matt Stewart.

“It gives them a bad name.”

Stewart is the senior automotive equipment analyst, kind of like the car expert, for the City of Chicago.

It owns four of these small electric vehicles.

And Stewart doesn’t like comparing them to golf carts because he says N-E-V’s are much more sophisticated.

“They can go faster than golf carts, I think golf carts are allowed to go up to just under 20 mph, these go between 20-25 is the top speed. They have safety glass windshields, they have mirrors, they have turn signals, brake lights, headlights, and then they have automotive certified safety belts.”

OK, so N-E-V’s are not golf carts–They’re road ready.

And fully electric.

The vehicles are charged with just a regular wall plug and can go up to 40 miles on a single charge.

And this year, Chicago’s approved these vehicles to drive around nearly everywhere in the city.

“Hi, Garrick.”

“How you doin’?”

Garrick Mueller is a truck driver for the city of Chicago.


We’re standing in this huge warehouse that’s filled with fire engines, garbage trucks, and of course, some N-E-V’s.

Mueller says he uses this little vehicle all the time to move around the warehouse.

We buckle in.

“We’re all set, you ready?”

“Yeah.”


“Alright.”

“This is wild.”

“Isn’t it? It’s pretty neat.”

“OK, so we’re about to go on a regular street.”

“Yeah, Elston Avenue, we’re going to make a right. People look at you, they’re like, what is that? See right there– the cops looking at us? They’re like, ‘What is that.’ It’s like when you see a new car on the street you’re like, ‘Wow, look at that.'”

“Now, the ordinance they passed would allow everyday people like you and me have one of these at home. What do you think about being able to drive this around your neighborhood?”

“You know, I like it. I would definitely drive one of these. I mean, the doors come off in the summer, if you had kids and stuff, you could go to the ice cream parlor, have them seat-belted in and go right to the ice cream, you know, it’s nice.”

“That’s actually the goal.”

That’s Eileen Joyce.

She’s assistant commissioner of Chicago’s vehicle fleet.

Right now, Joyce says the city’s testing out the N-E-V’s for its lighter travel needs.

Say a worker needs to drop off a box of pamphlets at a concert.Or a few employees need to drive downtown for a meeting.

Granted, those kinds of trips are the minority compared to most of the city’s work with large vehicles like garbage trucks and snow plows.

But Joyce says the city wants to show residents how useful these vehicles can be, and, if they catch on, she says it could make a big impact on reducing pollution here.

She imagines N-E-V’s parked in driveways and garages everywhere.

“Plug it in overnight, go and run errands, go to the grocery store, the library, Blockbuster, return something, and come back and plug it in without using any fuel or emitting any emissions into the air.”

Joyce says 39 states permit these smaller vehicles to be used in some form or other.

Some businesses have already started using N-E-V’s for things like food and pizza delivery.

So, you may not have seen one yet, but it probably won’t be long before you do.

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.

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.

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.

The company accused of “killing the electric car” says it’s going to bring a new version of plug-in car back to the market. General Motors recently unveiled plans for a new hybrid SUV. They claim the new technology will get double the gas mileage of any current SUV. But as Dustin Dwyer reports, the CEO of GM says he’s not sure when the vehicle will be on the roads:


GM CEO Rick Wagoner announced the hybrid project at the Los Angeles Auto Show. He said the vehicle would have the ability to be plugged into a wall, to use more electricity and less gas.


The announcement was part of a major speech on GM’s commitment to alternative technologies.


And, although Wagoner set no dates for when his company would have these technologies, Bradley Berman of hybridcars.com says the speech was a big first step.


“For so long, we didn’t even hear the right talk. How can you walk the right walk if you’re not even talking the right talk? At least now it’s the right message. It’s the right way of looking at it. And that sounds promising.”


Berman says GM still has a long way to go to catch up with rival Toyota on hybrid technology.
