Wasted

By Liz Bloomhardt

Published November 5, 2010


Fuqua Student (FS), you know who you are. You stood at the edge of the parking lot during graduate and professional student Campout with the bottom half of the hamburger bun in your hand and asked me, “Which one does it go in?”

Since this column isn’t actually about being wasted, which you may have been, and since this wasn’t your first time through the waste-free lunch sorting station, I challenged you to figure it out. You paused, looking down at the barrels and the signs, and claimed you didn’t know.

“Go with your gut,” I told you, assuming too much.

You threw that little scrap of bread in the trash.

“Wrong!” I told you. “Try the compost.”

FS, you embody a simple truth: Without me standing there waving my hands at the appropriate barrel, most people get equally flustered when confronted with this seemingly simple choice, or ignore it altogether.

Building to LEED II: A higher standard

By Liz Bloomhardt

Published October 22, 2010


In the seven years since the Board of Trustees adopted the current LEED standard to target a level silver certification on all new construction and renovation projects, the University has registered 27 projects with U.S. Green Building Council for certification. Despite the seemingly large number of registered projects, Duke is not yet getting the full benefit of its LEED commitment.

While “generally” resulting in better buildings from a maintenance and utilities perspective, John Noonan, associate vice president for facilities, informed me in an e-mail that “as we audited past LEED projects, we found a lot of emphasis placed on scoring points, and perhaps less so on focusing the points in areas that impact energy.” Specifically, according to a 2009 study of 20 LEED registered projects on campus, conducted by Nicholas School Masters student Amy Dao, Duke was only awarded an average 28 percent of the total number of energy points, while getting over 50 percent of the available LEED points in all other categories.

Building to LEED

By Liz Bloomhardt

Published October 8, 2010


I work in a building on campus. He’s a mean dude. He swallows me whole to a quiet place in his bowels, then hums and belches air in my face all day. He can’t decide if it should be hot or cold, though in the interior, it’s usually cold. Sometimes the heater is on, even though it’s summer.

My building has a neighbor, and she is clean and bright, full of daylight, with signs pointing toward the recycling bins and motion sensors on the lights.

I don’t work in a LEED building. But the building next door is a LEED Silver certified building. It has a plaque.

LEED distinguishes more than just old versus new, plaque versus no plaque. So, what is LEED? And what does a silver building have that mine doesn’t?

Back To Bikes

By Liz Bloomhardt

Published September 24, 2010

Last week the City of Durham issued a press release announcing its recognition as a bicycle friendly community by the League of American Bicyclists. Durham was awarded a bronze-level recognition, the lowest of four levels recognized by LoAB. Chapel Hill also received a bronze-level recognition. Close by Carrboro bested both college towns, achieving a silver rating. Several other North Carolina cities also received awards.

This publication picked up on the story this week, and Tuesday’s edition of Towerview magazine had a one-page spread on just how hip the bicycle commuting trend is for the fall. In true magazine style, the short blurb was accompanied by a shopping list to aid interested trend-followers in getting in on the act.

I hope bicycling is more than a fall trend, but I also applaud all of the publicity this healthy and fun form of transportation is getting!

Water World

Published September 10, 2010

Welp, Earl was a dud, but we sure could’ve used the rain.

All that sunshine and hot weather that was inescapable the last two weeks have been hanging around most of the summer while many students were off saving the world and being interns. Too much sunshine hardly seems like a bad thing until a lack of rain equals drought.

And I hate to say it, but we are experiencing a low-level drought.

Surprised? You probably shouldn’t be.

Bull City Connected

By Liz Bloomhardt

Published August 27, 2010

There’s some buzz around a bus. It’s in the newspapers. On TV. Even has a new hit single from ages past:

The wheels on the bus go round and round,

round and round, round and round,

The wheels on the bus go round and round,

All the way downtown!

You think it sounds childish? Already been done? Alright, but before you skip to the next column, let me back up a minute.

There is a new bus, introduced just two weeks ago. It’s yellow, but also orange, and no, it’s not taking you to kindergarten.

Here are the facts: It’s called the Bull City Connector. It has a website: www.bullcityconnector.org. It runs every 15 minutes from 7 a.m. to 6 p.m. and every 20 minutes from 6 p.m. till midnight during the week (on Saturdays, the bus runs on 20 minute intervals). The route starts at the Duke Hospital then moseys over to Main Street via Erwin Road before continuing all the way to Golden Belt, passing through town favorites like Brightleaf Square, American Tobacco District and City Center.

The best part: it’s free!

Going green at home

By Liz Bloomhardt

Published July 1, 2010

Since this is the send home edition of The Chronicle, it seems appropriate for the ‘green devil’ column to go home, too.

Most of the year I use this space to explore ways in which Duke is making progress toward its climate neutrality goal. Using the University’s Climate Action Plan as a road map, I’ve covered issues relating to energy, transportation and carbon offsets.

Why does it make sense to focus on what happens off campus? Of the four end-use consumption sectors measured by the Annual Energy Review 2008: Energy Consumption, a report published by the statistical arm of the U.S. Department of Energy, transportation and residential energy use make up the second and third largest sectors in the U.S. respectively. So what Duke thinks about and does on campus, you can think about and do at home too.

Constructing the Death Star... er, I mean... Ecomposter

Constructing the Ecomposter was not a lot like death, despite the warnings.


It came in a box.


The box came from China.

There were lots of pieces in the box, and they went together one by one. First there was one half...


Then there were two.

Two World Cup games after it started, the Death Star... er... Ecomposter, was ready to fill.


What's going in? From left to right, wood ashes (a "brown"), directions (not going in, but useful), a weekend's worth of vegetable scraps, coffee grounds, and eggshells (the "greens"), and fallen leaves (another "brown").


The idea here is to mix greens and browns in a 1:1 ratio to start, then to keep a happy moisture level thereafter. Load, then spin, daily. And, keep adding until full. Then let finish.


I will admit that it does not look delicious or nutritious right now. It looks like a mold pile waiting to happen, and it's likely to get gross before it's finished. But, provided this whole natural process works as advertised, once it's done, my plants are going to love this stuff!

Air, it's what we breathe

by Liz Bloomhardt
Published June, 24, 2010


It’s been hot. Really hot. And humid.

No surprise there, really. This is the South, after all, albeit June.

Here in Durham, the mercury has been getting a workout, topping out at or above 90 degrees for most of the past two weeks.

Along with this increase in heat has come an increase in the AQI, or Air Quality Index. The AQI number ranges from 0-500 with a color code from green to maroon in six colors. The number and corresponding color is a daily measure that tells you how polluted your air is and what consequential health effects might be of concern.

Death Star Composting

The first post in the new green@home category comes straight from woot.com.

Today's podcast on the site advertises a death star-esqe composter, and well, we got a little excited about that, and couldn't help but put in an order!

Here's the full story: for nearly two years, I've been on the verge of starting some sort of composting pile. In fact, just yesterday, I was perusing this site for information on composting and vermicomposting (worms). It's chalk full of great information from the NC Division of Pollution Prevention and Environmental Assistance.

I even had a bin picked out for the vermicompost bin (which I may still start). I just needed to get worms, but where? And that's when the project was just about to get pushed aside, just like last year when I only got as far as collecting pamphlets. The lesson here is that there are many, many ways to get started, so just do it. In our case, it took a death star.

Ok, to be perfectly honest the Eco Composter is not a death star, but it sure looks like one. Of course, once we get the box, we may change our minds. An Amazon.com reviewer had this to say: "This composter should come with a warning: 'Be prepared to abandon your life for the foreseeable future before committing to assembly.'"

"The Death Star wasn't built overnight!" responds my boyfriend.

We are engineers. This is only a challenge to our skills.

Check back for more, I'll have a report once we get the thing into action!

Summer Reading

By Liz Bloomhardt
Published June 10, 2010


Students never stop reading; I think it’s in the job description.

During the school year, as most of us know all too well, reading is likely to be assigned and topical. While not uninteresting, as a graduate student in engineering, that means my reading tends toward the academic—papers and texts full of math and nuanced details that can take hours, if not years to fully understand. So, I don’t usually mind when course work and the semester buzz wanes during the summer months, leaving a little more time to sift through the stack of books collecting on my nightstand.

Summer Reading Survey

It's summer time!

Time to catch up with family, do a little traveling and visiting, and barbecuing, and get all that stuff done that just didn't get done during the school year.

It's also a great time to dig through that pile of books that have been stockpiling on the bedside table for a good read -- maybe something to take with you to the beach.

Got any sustainability/green/environmental books that should be floating to the top of green devil's pile? I'm putting together my summer list, and I'd love to hear your recommendations!

Tar Balls

By Liz Bloomhardt
Published May 27, 2010

It is summer and time for visiting, so I was on the West Coast near Los Angeles this past weekend.

Standing above Laguna Beach, watching the beauty of the surf play against the palms, warm sun on my face, I looked down; three little tar balls, stuck to the bottom of my flip-flop, stinky, and full of sand and dead grass and little rocks. The far off storm that was kicking up the surf had also brought them ashore.

Appropriate, I thought, as there is an oil spill in the Gulf.

Apathetic to the fact that it was the 40th anniversary of Earth Day, the BP-leased Deepwater Horizon drilling platform sank into the Gulf of Mexico April 22, having killed 11 and leaving a broken wellhead gushing countless barrels of oil into the depths of the Gulf.

Oil Spills

It's been several weeks since the BP-leased oil rig exploded and sank in the Gulf of Mexico leaving a gushing oil well spewing countless gallons 5,000 feet below the surface. Much has been written in the weeks following the explosion as elected officials, scientists, and emergency crews converge on the scene, and everyone seems ready to offer their thoughts.

Well, here are a few of mine.

After my initial wave of guilt for consuming carbon during a drive to school last week (I was listening to a radio program on the now national disaster at the time!) I got to wondering if this wasn't a new generation's Exxon Valdez. Being in my mid-aughts at the time of that disaster, I remember little from the coverage and response at the time. When I asked my peers, they also say they were too young. I can only imagine then that today's college age students were infants, if they were alive at all. It was the 80's after all.

Happening at the worst time in the school year, with students in exams and preparing for graduation -- on college campuses at least -- it's just another news story. There's a run on sea food, turmoil in Greece, elections in the UK, unrest in the financial markets... oh well, at least the plan to capture the spewing oil made it on the Daily show last week. Maybe someone does care.

I'm not sure what I expected the response to be exactly, but at least at the beginning, it hasn't been particularly emotional. Photographic evidence of the devastation has been limited, both by weather and the fact that the oil isn't yet heavily impacting the shoreline and marine life. Without that emotional draw, its less quantifiable, less real, less dramatic.

It's possible that as the story persists in the news media, the emotional response will grow as was the case with the Exxon Valdez disaster. For instance, the recent release of video from the sea floor of the gushing pipes are an eerie reminder of the toxic cloud gathering below the surface of the gulf. It may take much longer for the especially emotional footage of impact to birds and shorelines to appear though.

The recent introduction of a climate bill in the US Senate will allow the political fall out to develop as well. The Exxon Valdez disaster led to several legislation measures, including requirements that oil companies have disaster plans in place, and requirements for double-hulled ships. Only time will tell if this disaster will be capable of coalescing the necessary political power to push forward on another round of legislative and bureaucratic initiatives.


Over the coming months I plan to report back on the effects the disaster is having on the dialogue and behavior in the Duke community. I welcome comments on your experiences with the Exxon Valdez disaster, and any parallels or comparisons that may be drawn with the Deep Water Horizon disaster. Stay tuned.

CDC: Week 3

Cars are expensive. So is commuting.

A recent study of the Boston metropolitan area indicates that while people moved to the suburbs to save money on housing, they in fact spent more than their urban counterparts on transportation and commuting, effectively neutralizing any savings they may have gained.

Granted Durham isn't Boston, for starters its much more affordable to live here. While the Boston study area ranks with the most expensive places to live in the country, not so in Durham.

But the Bull City is designed for commuters. Much of the county is occupied by suburbs and more than 25,000 students faculty and staff hold permits to park on Duke's campus.

Anecdotally, when I first moved here, my commute was no more than 5 miles. After living in Boston, where my job required me to drive all over the state, sometimes several hours every day, filling the gas tank every few weeks here seemed pretty fabulous. And on a student schedule, there was little traffic and low hassle (except that parking was across campus!).

But gas is just the start of the expenses that come with owning and operating a motor vehicle. When you include registration, taxes, insurance, inspections, maintenance, and possibly the occasional parking or speeding ticket, it can really start to add up. I can testify to that!

The real question is weather knowing the true cost would change behavior and choice.

My Carbon Diet Challenge

By Liz Bloomhardt

Published April 22, 2010

Today is Earth Day.

What a day for a “green devil” column.

I figured with all the earthy stuff going on today and this week (i.e. Duke’s celebration and concert on the Plaza today and Durham’s Earth Day Festival Saturday), I had to kick it up a notch for this column.

So I went on a diet, a carbon diet that is, and I called it my carbon diet challenge, C.D.C. for short.

Now, I’m not into diets as a general rule. But sometimes a catalyst is required for change.

Carbon Diet Challenge, Day 7: Carpools

Today I checked out the Duke GreenRides program -- a carpool matching service offered through the parking office.

After a short survey in which you fill out your location, time preference and several personal but not overly invasive questions, the database offers you matches and a form email to initiate contact.

I stopped after filling out the profile. Beyond my hesitation to meet people over the internet, I have to admit to not being fully committed. This, mostly because I tend not to be a particularly habitual person, in which case biking and regular bus service offer an attractive alternative that allow for a more independent and irregular schedule. Since I'm still exploring those two options, I'll let the bait dangle for a bit before I dive in further. For now though, my hat's at least in the ring.

CSA Starts Today!

Today was the first day of the 2010 farm share season!

For the past two years I have participated in a community supported agriculture (CSA) program. Every week, I get a box of vegetables that have been grown in North Carolina by the farmer I signed up with at the beginning of the season. Several of the participating farms drop off at locations around the triangle but I get mine at the Sarah P. Duke Gardens, a drop-off location organized through the benefits program of Duke employees. The program, though, is open to anyone.

The idea is that you pay a flat rate at the beginning of the season, and get a weekly cut of the produce the farm harvests. Duke's program has several farms to choose from at a range of price points and usually two or three share sizes.

Farm shares are especially advantageous in a state like North Carolina which has a long growing season and a healthy agricultural tradition. We like it because we're not only developing a relationship with the farmer, but we hardly have to think about vegetables all summer. Shopping lists get shorter and the volume of veggies in the diet goes up. We also get fruit, and that's probably the best part.

Well, I guess this means it's probably time to break out the recipe book and get cooking!

Student U

By Liz Bloomhardt

Published April 8, 2010


In between basketball games and egg hunts this past week, you may have noticed an annual occurrence: Everything turned green, seemingly overnight.

I find it hard not to link this profusion of pollen and photosynthesizing surfaces with another event last week, one slightly less noticeable.

It all started over a cup of coffee.

Amy Morsch, former president of Duke University Greening Initiative and a graduate student in the Nicholas School, and I, coffee drinker, met one morning last semester in Joe Van Gogh. We were there to discuss projects and campaigns, and the hurdles student groups face in marketing them to the Duke community. We wondered what the undergrad groups were working on, and if they felt like they were doing the same leg work year after year.

Carbon Diet Challenge, Day 2: Telecommuting

Telecommuting, a.k.a. working from home; a.k.a. rolling out of bed and into your desk chair, within reach of the coffee maker.

Can you telecommute as a grad-student? Is it a good idea?

That all depends. Like any job, life as a graduate student is dictated by your relationship with your boss, so my adviser, and the work that I'm doing. Mine is one based on trust and results.

If I need to be in the lab running an experiment, I can't telecommute. If I need to be in class, no telecommuting. Meetings, presentations, and group work also require my presence in the flesh, on campus. However, on days when I'm running Matlab programs, making plots and sending emails, the wonders of technology mean I can be anywhere. And if I'm bringing results to the table week after week. The "where" is not a problem.

Wander down to the coffee shop? Sure. But I never do. I find my little folding table under the window is sufficiently isolated, and stimulating to provide for a full day of productivity. Certainly, it's far superior to hours spent under the vent blowing bad air into the cinder-block cave that is my office on campus.

On the other side of an improved state of being and productivity, louder music and a zero-emission commute there are the pitfalls and hazards. Most notable, is that by not being on campus I miss stuff. Events, seminars, lingering conversations in the hallway, or time commiserating with my group mates about the daily tribulations of graduate school. Considering the usual graduate M.O. is working until 5 AM, caffeine binges, and late night fast food, this can be serious missed bonding time. On second thought, that's not my typical schedule regardless of work location...

Anyway, the point is that balance is the key for anyone considering and able to telecommute. I can't, and won't do it every day of the week, and I shouldn't. But on some days, like today, it's great to stay out of the pollen while getting just as much done as I would anywhere else.

Carbon Diet Challenge, Day 1: Pollen Storm

I picked the wrong week to start bike commuting.

Last weekend, the trees unleashed a storm of pollen that has been terrorizing the area. Pollen has become so prolific that I'm afraid there might soon be trees sprouting out from between the keys of my laptop. It's on every surface, and it's getting kicked up with the wind forming little pollen-devils and pollen-clouds. It's as bad as a sand storm in the desert.

To say the least, this is not ideal conditions for biking. I hadn't even left my neighborhood today before I was wondering how many gallons of saline it was going to take to flush the pollen cakes out of my eyes. Though I'm still coughing, and rubbing my eyes, I'll try to move past all that and focus on some of the thoughts spurred by the beginning of this experiment.

I'll start off by saying I don't recommend bike commuting to everyone. I happen to already be a fair-weather cycling enthusiast. I own a bike, helmet, and appropriate gear. I'm in decent shape. I'm thinking of this adventure not as a great tidal shift, but as providing some impetus for an activity that I've always thought about doing, and have wanted to do for some time.


Day one is a good idea to consider a route. If you're thinking you'll just navigate over to the new google.maps "by bike" capability -- not so fast! In the Durham/Chapel Hill area, this will not always get you on a safe, repeatable route. For instance, it put me right onto 15/501 from I-40 to Academy Rd. Anyone who's ever driven this 45 mph stretch, currently with construction, has thought to themselves: Now, why isn't this a highway? It's a box store wasteland, with stoplights and traffic that won't quit, especially during commuting hours.

Being somewhat familiar with the surface roads, I chose to follow the same path I drive to work, down Old Erwin. It's still pretty busy, but it has some shoulder, and a nicer view.

To avoid major overlap with the morning traffic rush, I sent off a few emails from the home office before gathering the bike supplies and hitting the road. I encountered fewer cars, but at least one large truck, which I will admit, is a scary experience.

The ride home, which I did not time as well, was an experience being on the other end of the line of commuters waiting patiently for the first car to work up the nerve and space to sneak around the biker. Unfortunately, even if I'm going a blazing 25 mph (kinda fast on a bike), that's an agonizing crawl to the internal combustion community.

So, here are some thoughts from the first day:

1. Share the road. Drivers: be patient with the biker, and no, I don't think it's necessary to swing all the way into the other lane. There is such a thing as passing safely without threatening the oncoming traffic, yourself, and the cyclist. Cyclists: stay on the shoulder, minimize swirving, use hand signals, and keep a constant speed. There is room for everyone.

2. Casual skirts make for excellent post commute attire. One of the frustrating things about bike commuting is the sweaty, just wiped off the make-up and ruined my hair, I'm still sweating in my new outfit even though I've been in the office 20 minutes problem, especially for the ladies. I don't think I'll be able to do the bike thing if I have an important meeting or presentation. Luckily there's a bus, at least during the school year, but I'll have to overcome the bus hurdle first...

3. Storage. I will not leave my bike outside. I spent good money on it, and I refuse to leave it to the weather and the vandals (not that I know if this is a problem). It's in my office during the day. So are my sweaty bike clothes. I also have office mates, so this is an issue.

4. Distance. There is probably an ideal bike-commuting distance from campus. My guess is that I would fall outside that circle. That doesn't mean that I can't be maverick, it just means there's more risk, because there's more miles, and more time out on the road. In fact, it took me 45 minutes door-to-door on day one. That's about 10 more than my car-commute. And people have died on the Durham roads during routine commutes to work. It's just not worth that.

5. Stress. Especially with the commuters on the way home, I had to be focused. There were lights to pay attention to, people passing me, me passing people. It's so much easier when I can lean back in my leather seat with the windows down and the radio blasting all the way home. For everyone on the road, this is something to be aware of. And no TEXTING! I can see you!


Happily, the weather was nice today, despite the pollen. I lost steam, though, on the way home, and slowed to a crawl. My back hurt, my sit-bones hurt, my legs were drained. Not a good way to start the experiment, but perhaps expected as it's been months since I've been on my bike, let alone with a backpack.

Not to fear, I will persist. But for now, I'm settling in for the evening with a beer, and my feet up. I think I earned it.

A challenge for the green devil

I recently completed the carbon calculator on the Duke Sustainability website. It was part of an email I got from the Green Devil Challenge campaign (no relation to this column).

Overall I think I did pretty well -- I would need to plant 55 seedlings, growing for 10 years to offset my annual footprint. My relative ratings in three of the four categories -- energy, diet, and behavior -- was "Low." These numbers don't necessarily mean I'm doing everything right, but I do live off campus, so carbon emissions associated with my living situation don't come into the Duke equation. If I lived in the dorms, it might be a different story. Since, I don't eat on campus much, or work in my office all day, those contributions are also low. I also do my best to recycle, and I think I got points for that.

What I didn't score so well in was the fourth category: transportation.

Apparently I have an average commuting footprint for a Duke community member. My annual carbon footprint associated with transportation -- based on the generic questions I answered in the survey -- is roughly 1.7 metric tons of carbon equivalents. That's more than two thirds of my total footprint. I was okay with this for a while, but then I asked myself, who wants to be average?! At anything! I do go to Duke after all, a school that prides itself on being above average.

So I'm putting myself on a carbon diet. I'm setting my own challenge: a challenge for the green devil (note the lower case).

For a week, I will stop driving my car, and bike to school, or take the bus. I will post my thoughts on this experiment on this blog, and hopefully talk about the experience in my final column of the year, which will run on Earth Day.

Stay tuned!

(As a side note, I encourage everyone with a netID to navigate to the Duke Sustainability web page, log in and sign the pledge. Then take the challenge for yourself!)

Managing Green

This will be the first post that steps away from the established format of this blog, that is, an archive of my published Chronicle columns. But, change is a wonderful thing, and it is my hope to use this blog to explore more issues relevant to the Duke Sustainability movement than I have time or space to cover in the column.

So first up, a recent article that was forwarded to me by a fellow Jumbo which summarizes data from a survey conducted by McKinsey & Co. The report, titled "How companies manage sustainability" can be read here.

There are several interesting conclusions that are drawn from the results, but what I find particularly interesting to marinate on, is the idea that "engaged" companies are far more successful at reaping benefit from their sustainability efforts in the form of improved reputation, cost savings and growth opportunities.

Perhaps this particular bout of fascination stems from the fact that I just navigated my browser away from Ben & Jerry's corporate site. In the chronicling of the company's history is an interwoven story of its Environmental Action commitment and accomplishments. Sure, they make great ice cream, but a strong commitment from the founders has meant employee involvement in internal committees and programs that have accomplished significant changes in operations and waste reduction from bulk ingredients packaging.

But what does an ice cream manufacturer have to do with Duke? Well Duke is also engaged, and no I'm not just referring to the service-learning program, Duke Engage. Starting with a commitment at the top, the University has established dedicated positions focused on organizing, motivating and enabling sustainable changes. In addition to a willing ear, there is funding available to anyone within the Duke community to start a sustainability project or program. If the McKinsey report is any indication, this commitment and established framework are the first steps to making realizable gains and improvements.

As I sit enjoying my recently purchased pint of Chocolate Chip Cookie Dough, I can only hope Duke will have it's own scrapbook of accomplishments some day, just like Ben & Jerry's.

Published Online March 25, 2010


The overarching goal of the Duke Climate Action Plan is to achieve carbon neutrality by 2024.

On a fundamental level, the idea here is to make operations as efficient as possible. Loyal readers will recall from previous columns some of the mechanisms and policy changes outlined in the CAP that aim to reduce the University’s carbon footprint. Some of the changes, like the East Campus Steam Plant and temperature standards in campus buildings have been implemented. Others are under consideration.

Increasing efficiency however, will never get us to zero.

Do it in the dark: Part II

By Liz Bloomhardt
Published Online March 5, 2010


The Duke Climate Action Plan sets out ambitions goals for future energy reductions. Using a wedge based approach to classify opportunities, the Energy Sub Committee of the University Campus Sustainability Committee, or CSC, has identified significant emissions reductions on campus over a projected 40-year time horizon.

The largest wedge in the energy analysis pie estimates Duke Energy will be responsible for 60% of emissions reductions in 2050, 40 years out. Tavey Capps, Duke’s sustainability coordinator, told me in an email that the CAP assumes these reductions based on information provided by Duke Energy, a publically traded company.
