Tesla Motors Shoots for Bigtime

If you want a clean electric vehicle to cruise the highway today, you really only have one option – a small, Silicon Valley company named Tesla. Tesla has plans to be a big player in the auto industry, but so far the company has only built a few hundred cars. Dustin Dwyer looks at whether Tesla can make it in one of the toughest industries around:

Transcript

If you’re trying to get attention for a new vehicle, a big auto show is one of the best places to get it.

And even this year, as GM and Chrysler hobbled into the Detroit auto show on federal life support, and all carmakers scaled back, there was still a lot of hype.

Here’s GM’s introduction for the Chevy Volt.

“Ladies and gentlemen, the future of automotive transportation has entered the building.”

That’s how the big players make their announcements.

Tesla is not a big player.

CEO Elon Musk made his big announcement in a hotel conference room in front of a bunch of geeky auto analysts.

“A big announcement that I’ve just gotten this morning permission this morning to make is, um” (takes drink)

Here he takes a drink of his water.

“…that Daimler has given us permission to acknowledge that they are the automotive partner that we’re working with.”

That means Tesla is going to help make an electric version of Daimler’s tiny Smart Car.

Musk is not much of a salesman. But maybe he doesn’t have to be. While all the big carmakers are seeing huge sales drops, Musk says Tesla sales keep going up.

“And, well, actually we can’t produce them fast enough and we’re sold out through November of this year.”

Now, Tesla – at most – makes 30 vehicles a week. And its only car, a sporty roadster, sells for more than $100,000.

A company like GM sells thousands of cars a week, and people who aren’t movie stars can actually afford some of them.

But Musk says he wants Tesla to be more than just a small time player.

So now the company is working on a four-door sedan that will sell for about $50,000 – still pricey for most of us, but half the price of its two-seat roadster.

Here’s the thing though, right now, Tesla has the electric vehicle market all to itself. But all the big companies are working on their own electric cars.

So when Tesla comes out with its four-door sedan, the competition will be much tougher.

Michael Robinet is an auto industry analyst with the firm CSM Worldwide. He says Tesla’s small size is a problem.

“Economies of scale is one of the main drivers of this industry to get cost out of the vehicle and be competitive. And that’s where the major vehicle manufacturers are going to have a leg up in the future.”

Some who follow the auto industry think Tesla’s future could be as more of a partner to existing companies, like what Tesla is doing with Daimler.

But Elon Musk insists Tesla will continue to make its own cars. And it can succeed.

“You go through sort of stages of denial, I guess. You know, when we first said we’d make this car, people said you can’t make this car. It’s not going to work, the technology’s not going to work, and even if the technology works, nobody’s gonna buy the damn thing. And we’ve shown, hey, we can make the technology work and people really want to buy it. So, okay, then they go to the next stage, ‘Oh, well, sure, okay, people will buy that car, but they won’t buy a sedan.’”

Tesla plans to unveil the new sedan later this month (March 26). The car is expected to go on sale in 2011.

In the meantime, Tesla has not been completely immune to all the problems facing the auto industry. Tesla had trouble raising money last year to finance the new sedan. So it turned to the federal government for a 350 million dollar loan.

At least in that one sense, Tesla is already acting like a major player.

Pint-Size Cars Sip Energy

Neighborhood Electric Vehicles (N.E.V.'s) can go up to 25 mph. The City of Chicago would like to see more people using them for short-distance errands. (Photo by Mike Rhee)

Hybrid cars are all the rage nowadays.

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

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.

Saving With a Smart Grid

The government is spending billions of taxpayer dollars on a new “smart grid.” Mark Brush reports the new grid could eventually save you money on your energy bills:

Right now – power just goes from point A to point B.

But with a smart
grid system, your house can talk back to you and the power station.

The
meter could tell you how much it costs to heat your water, for instance.

And the power company will be able to talk to you if they’re having a
problem.

So, if they’re headed for a blackout, they can text message you
or e-mail you and ask you to shut off your A/C.

Jesse Berst is the founding editor of Smart Grid News dot com. It’s a trade publication.

He says, if electric grids are updated across the country, it would cut
down on pollution and save money.

“And that means there’s billions, tens of billions of dollars of power
plants and lines that we wouldn’t have to build over the next couple of
decades.”

Upgrading the system won’t be easy.

Each state has regulatory agencies that oversee thousands of electric
suppliers.

So there will have to be a lot of coordination.

Google’s Power Meter

Google's new smart meter technology will eventually let consumers see how much energy each appliance (like a fridge) in their home uses, in order to help them find ways to reduce their monthly bill. (Photo by M. Minderhoud, Courtesy of Wikimedia Commons)

There’s 11-billion dollars in the new economic stimulus plan for upgrades to the electric grid and so-called smart meters. These smart meters hook up to your home and give the utility company real-time feedback on how much energy you’re using. Rebecca Williams reports Google is working on a way to let you see that information:

Transcript

Google’s system is called PowerMeter. It’s in beta testing right now but the idea is: if you get a smart meter, you’ll be able to see exactly how much energy your TV, fridge and computer use.

The system will hook into the info utility companies draw from your home. Then, you can log into your secure i-Google website, for free. And get real-time feedback so you can figure out how to spend less on your power bill.

Kirsten Cahill is a program manager at Google. She says they’ve been testing the PowerMeter around the office:

“I think people are surprised about things like their oven; how much the oven uses or the microwave. Things that you using every day that are actually, you know, pretty huge energy users.”

It’ll probably be a year or more before the Google system is open to everybody.

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.

Ice Storm Reveals Dated Power Grid

Hundreds of thousands of people in the lower Midwest are still without electricity and heat because of an ice storm. Lester Graham reports the storm shows that the electric power grid is fragile:

Transcript

Hundreds of thousands of people in the lower Midwest are still without electricity and heat because of an ice storm. Lester Graham reports the storm shows that the electric power grid is fragile:

People who tried to stay at home are running out of supplies and now heading for shelters. Rachel Harper and her three children are staying in a shelter in a church basement staffed by Red Cross volunteers from around Bowling Green, Kentucky.

“We’re doing okay. They’ve been watching movies, playing games. Just trying to be together as a family.”

Others are trying to stick it out at home. Mike Jarvis was stocking up at a Wal-Mart.

“I’ve got a wood heater and we’re cooking on the grill, so we’re doing okay.”

In the hardest hit areas, power crews say it will be two more weeks before they find all the downed lines.

The stimulus package includes money for automatic meter readers that could help find downed power lines faster.

Patrick Levine is with the National Rural Electric Cooperative Association. He says that technology could help.

“There is probably an opportunity to more quickly identify which consumers are without power.”

The ice storm revealed just one of the weaknesses in the grid that’ll have to be upgraded if we’re going to start using electricity to power our cars.

Mountaintop Mining (Part Two)

Gary Anderson in Front of Coal River Mountain (Photo by Sandra Sleight-Brennan)

Mountaintop removal coal mining blows off the tops of mountains to get to a thin layer of coal. Environmentalists say there’s a better way to extract energy from mountain tops. They want to put up wind turbines. Sandra Sleight-Brennan reports they believe it will mean more energy in the long term and less environmental destruction:

Transcript

Coal River Mountain is one of the last in Raleigh County West Virginia, and it’s next in line for mountaintop removal mining. A local group, the Coal River Wind Project, wants to build a wind farm along the mountain’s ridges.

Lorelei Scarbro has lived most of her life in the West Virginia coal fields. She’s the daughter, granddaughter and widow of coal miners. She knows her opposition to coal mining is seen by her neighbors as a direct threat to their jobs.

“It has been difficult. But people begin to understand that we’re not trying to take something away from them. You’re trying to add something to the area.”

She says mountaintop removal coal mining is short-term gain with long-term damage.

“The pace we’re going; it will be nothing left. I have a five-year-old granddaughter, and I can’t imagine what the air and water will be like when she is at childbearing age if we continue at this pace, because they’re covering headwaters streams, they’re starving off the water supply, they are destroying the air.”

And the next mountain in Scarbro’s home area to be mined is likely Coal River Mountain.

That’s why Coal River Wind Project commissioned a study to see if wind turbines would work. It turns out, the mountain has industrial strength wind. Enough to power 164 turbines. The project would create 200 local jobs during construction, and 40 permanent jobs. Rory McIlmoir is the project coordinator.

“The wind farm would generate an average of $1.74 million a year for the first 20 years. In year one it would generate over three million dollars. That’s the property tax. Blowing up the mountain for coal, on the other hand, would only bring $36,000 back to the county.”

That’s just the property taxes. The wind farm would make about $1.75 million dollars a year in revenue according to the study.

But the wind project has hit a stumbling block. A recent Bush administration rule change allows mining waste to be dumped into streams. That’s cleared the way for the West Virginia Department of Environmental Protection to approve a permit for Massey Energy to do mountaintop removal mining here. If the mining occurs, the mountains would be lowered by several hundred feet. That would scrap the wind turbine project.

Activist Lorelei Scarbro thinks the wind project is the one thing that can stop the destruction of Coal River Mountain and others targeted for mountain top removal coal mining.

“It will save the mountains, it will save the wildlife and the hardwood forests and the vegetation and the water. It’s something that is desperately needed. Of course, our biggest obstacle is the fact that that the land is leased to the coal company.”

But the people who own the land say, if coal mining were stopped by the government, they’d consider the wind farm. The wind farm project coordinator, Rory McIlmoir, says they’d benefit for a lot longer if they did.

“Because, if they can make a few million each year from royalties then they’re interested in that. But, the choice right now is easily coal.”

The Coal River Wind Project has presented the study to West Virginia’s Governor. And 10,000 people signed a petition asking the state to think beyond coal and think about the future of energy, the economy, the mountains and the people.

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:

Transcript

(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.

Lifting Bans on Nuke Power Plants?

The nuclear power plant in Braidwood, Illinois, was started up just after the state banned new nuclear power construction. For its entire history, it's been operating without a permanent home for its spent nuclear fuel. (Photo by Shawn Allee)

There’s been plenty of buzz
about dozens of proposed nuclear power
reactors in the US. Well, Wall Street’s
financial mess is making power companies
scramble to find all the investment money
for them. But, in twelve states, it won’t
matter whether power companies have cash
in hand or not; it’s illegal to build new
nuclear power plants there. Shawn Allee
reports there are efforts to repeal some
of those bans:

Transcript

JoAnn Osmand represents a state legislative district in northeastern Illinois.

Nuclear power is close to her heart – there’s an old, dormant nuclear power plant in her
district. Osmond thought, maybe that plant could be useful again. So, she sat down with
the plant owner.

”And I asked a question: ‘Why are you not taking some of the parts away and
putting them in other nuclear locations?’ They said, ‘there’s a moratorium, we’re
not building any more nuclear plants in the state of Illinois.’”

Osmond was stunned.

Illinois has six existing nuclear power plants – she didn’t know it’s illegal to build more.
She hears plenty of gripes about energy prices – so she thought, why leave nuclear energy
off the table?

“I don’t want my granddaughters to have to buy their electricity from another state.
I want to be able in 2020, 2030 to be able to plug in our electric cars.”

Osmond’s bill to lift the moratorium stalled – it’s still illegal to build nuclear power
plants in Illinois. California and Wisconsin recently had similar fights over their nuclear
moratoria.

Some veterans of nuclear politics are shocked anyone would want to life a ban on nuclear
power plants.

“It makes absolutely no logical, rational sense in any mode of analysis.”

I find Dave Kraft at a coffee shop. Kraft is with the Nuclear Energy Information Service,
a group that’s worked against nuclear power for almost thirty years.

Twelve states severely restrict or ban new nuclear power plants. Kraft says seven have
language almost identical to Illinios’.

“The moratorium simply said, no more new construction of nuclear reactors until
the federal government has a demonstrated means of dealing with the waste
permanently.”

Kraft says states tried protecting themselves from becoming dumps for the most
dangerous nuclear waste – the radioactive spent fuel.

The federal government is supposed to store spent fuel – maybe in Yucca Mountain,
Nevada. But so far, that hasn’t happened, so it’s piling up in nuclear power plants – like
this one in Braidwood, Illinois, southwest of Chicago.

(sound of a door)

Bryan Hanson manages the Braidwood power plant. He leads me to a square storage
pool. It has the bluest water I’ve ever seen.

Hanson: “This is where we store our spent fuel. It’s about thirty feet of water
between us and the top of the fuel bundles down there. So you’re looking at thirty of
water and another twelve feet down below.”

Allee: “If you look into it, it’s almost like honeycomb.”

Hanson: “Honeycomb … looks like an egg crate or honeycomb. Within those cells
are fuel bundles that have been used in the reactor, generated energy, and now
they’re waiting for eventual disposal.”

Braidwood’s pool was meant for short-term storage, but spent fuel’s been stored here for
nineteen years. Hanson says the company is planning for when spent fuel will have to be
stored on-site, but outdoors, perhaps for decades.

It’s a situation the nuclear industry’s is unhappy about, but it’s confident the federal
government will come up with a solution – some day.

So, most power companies support removing bans on new plants. This drives critics like
Dave Kraft crazy.

“To build more reactors at a time when we have no place to put the waste makes no
sense at all. The first rule of waste management is, stop producing.”

Even though Kraft says it doesn’t make sense to lift bans on nuclear power plant
construction, he predicts those bans will get challenged again soon.

Greening Your Computer Usage

Follow the 'turn it off' advice and save, on average, $75 a year. (Source: Julo at Wikimedia Commons)

The average personal computer is a real energy guzzler. Only about half of the power it
uses makes videogames run, or music play, or run office software. The other half goes
up in wasted heat. Shawn Allee found out there are energy-saving PCs, but maybe using
the computer correctly can save the most power and money:

Transcript

I want a peek at some energy-saving PCs, so I head to a Best Buy electronics store.

“We’re heading to the computers.”

“Yes.”

I’m with a store manager. He wants me to use his first name, Tim.

Shawn: “When people come to the store, what’s usually the thing they’re asking
about or looking for in their PC?”

Tim: “First thing they look for is memory and hard drive space, that’s pretty much
it, and price.”

Shawn: “So it’s like, what can this thing do, and how much is this gonna cost me?”

Tim: “Exactly.”

Shawn: “How often is it the case someone comes in and says, Tim, which one saves
the most energy?”

Tim: “I have never heard that question asked.”

Shawn: “How long you been doing this?”

Tim: “I’ve been with Best Buy for five years.”

And you know, when I ask shoppers about energy consumption and computers, I just get
blank stares.

Well, Tim’s got several computers that have thumb-sized Energy Star labels.

Energy Star rated computers cut energy use by a third, and they usually cost the same as
comparable models.

This can save an average user maybe $25 a year in energy costs.

There are people who say that’s not enough.

You can actually save three times that by using PCs right.

One guy making this case is Pat Tiernan. He directs the Climate Savers Computing
Initiative, a computer industry group.

Tiernan says no matter how you get a PC – new or hand-me down …

“Make sure power management settings are aggressively set.”

Those are in the computer’s control panel settings.

Tiernan wants people to give power-settings the once-over, just to make certain the
computer can detect when you’re not using it.

“It puts it into a lower energy state like sleep mode.”

That’s if you don’t use the computer for fifteen minutes.

That’s the biggest energy saver.

Tiernan’s next tip is to simply turn off the machine when you’re not using it.

“It’s funny to me, people don’t just leave their cars on when they’re done with them,
right? They don’t leave them running in the garage or on the street. Yet, most
people in the U.S. leave their devices on in one form or another.”

Now, Tiernan says, there’s turning off a machine and there’s really turning off a machine.

“Even though you’ve turned many devices off on your household doesn’t mean
they’re not using power.”

Tiernan says computers always sip a little electricity out of your wall socket.

Printers, computer speakers and monitors can, too.

“Put your devices on a power strip. Flip that switch off and you’ll be doing yourself
and the environment a benefit.”

Now, there are critics of turning off your PC.

Shawn: “I have heard in the past that turning your desktop on and off again is hard
on your hard drive, though.”

Tiernan: “Well, a hard drive is and spinning up and spinning down throughout its
entire use. Does it put added wear on your hard drive? It really depends. Depending
on what you have loaded on it, your disk may be spinning up and down anyway, so
there’s a good argument to be made that turning it shutting it down for 8 hours that
you sleep may be better.”

So, what’s the bottom line if you follow Tiernan’s ‘turn it off’ advice for your PC?

On average, you could save $75 a year.

You can save even more if you use an Energy Star model.

But Tiernan says cutting power doesn’t just help your bottom line.

He says there’re more than a billion PCs on the market.

Cutting their power use can take a bite out of climate change.
