Carbon Dioxide - finding out is a problem

I've been blithely quoting stats on my CO2 usage for a while now and you may (or may not) have wondered how I was calculating them.

I've got a spreadsheet. This will probably not surprise you.


I was updating my little spreadsheet yesterday, and hit the problem that is probably the biggest reason more of us aren't doing more: it's just so hard to work it out! I've been using estimates from various sites for a lot of my stats and I decided to dig a bit deeper.

As far as I know, my biggest CO2-releasing activities are:
- electricity usage at home
- petrol usage in my car
- co-generation which heats my water
- flying around the globe so much

I set out to tackle them in that order. So, here's how I worked out the home-electricity thing. My power comes from Mercury Energy.

Mercury Energy is somewhat coy about how much CO2 is produced by their power generation. I followed a tortuous path from the Mercury Energy website's blather about the environment, which told me precisely zip except that their power is generated by Mighty River Power....

.... so off I go to Mighty River Power's Generation page, which at least told me that they had a bunch of hydro stations (yay!), some geothermal (more yay!), a "biomass energy" station or three (a what?) and a co-generation plant, and that they were thinking about wind. So far so sweet and all but still no mention of CO2.

Some random clicking within the Mighty River Power site brought me to their Reports & Documents section, and from there to the 2007 sustainability report (large PDF).

And there, on page 18, in teeny font, was a CO2 breakdown by plant type! Hooray! And even better, on the following page, they've got a CO2 usage measurement for their corporate activities.

So, they generated 5,339 GWh of power and created 385,061 (love that 1) kg of CO2 in the process.

Armed with that data and a recent power bill I can now calculate that my 8 or so kWh per day results in about 0.58kg of CO2 being released per day into the atmosphere. This is data that should be on my bill, rather than requiring me to hunt through so many pages online.

So my questions to the internet today are:
  1. is there any way to get this data about all the power companies, easily and online?
  2. how does your CO2 production from your home electricity stack up?
  3. and do you agree, that this data should be on our bills?
(Interestingly, I originally ran the calculation on 2005 data by mistake, and on that data I would have been producing only 0.48kg of CO2 per day. Unless I'm mistaken, that means Mercury have been getting LESS green over time. I've done my little bit today by signing up for online billing.)

Once in a decade storm? and eating locally


(Image nicked from MetVuw)

Man, it's windy. The Metservice site is down so I can't tell how windy it is, but I can't see the North Shore and the rain is going sideways. The Herald was getting all excited about the weather earlier, saying the lows would be a new record. But they've been getting increasingly excitable about the weather since this new "weather blog" thing with Philip Duncan started up. Are we really such a boring country we need to blog about the weather? Er. On to other topics...

My building creaks in the wind. It's like living in a giant tree. I suppose that makes me a little bird in a nest. In a normal wind it sounds a slow creeeaaaak..........creak......... creak....... Today it's creakcreakcreakcreakcreakcreakcreakcreak.

But I'm pleased to see that the White Lady is open for business despite the weather. Mmm, dodgy cheeseburgers. I wonder what they taste like when I'm sober.

Speaking of food: I've been buying my groceries at the Britomart Farmers' Market for the past few weeks; I'm trying to "eat local, think global" now that I'm back home. Because it's the middle of winter, only winter veges are available and I've been forced to be a more adventurous cook. No pasta and tomato sauce can be made when there are no tomatoes or pasta! I made this beef rib stew with fore ribs from Te Kainga farm and baby carrots and potatoes from the market the other night - it's delicious.

So go, buy food there next weekend.

And while you're doing good for the earth, go have a look at getacross.org.nz - they're a group trying to get a non-car harbour crossing sooner rather than later. I for one would like to walk across the bridge without paying $70 to do it as part of a half-marathon.

Enough! it's dark and stormy outside so I'm going to snuggle down, watch LOTR again, eat stew and drink the rest of the bottle of red wine that I had to open (sigh) for the stew. And maybe it will be less than two months until my next post.

Mission: Nearly Impossible (rant)

Caution: self-indulgent rant follows. You might as well skip it and wait for the next update, which will be more cheerful.

My mission, and I had little choice but to accept it, was to get some new contact lenses. A simple enough task, you would think.

I first tried in Memphis. I was there anyway, and I thought what the hell, it's a major city, they're bound to have a few lenses to spare and I'm on my last pair. I'd seen ads for Sears Optical so off I toddled. In a sweet, ever so polite, Southern accent I was told that it was Sunday and they couldn't sell me any lenses. Grumbling only very slightly to myself, I toddled away again and threw my credit card at other more interesting things which were allowed to be sold on Sundays.

My next attempt was the following weekend in Little Rock, with a little more verve this time (my eyes were starting to hurt). I let my mouse do the walking, and found a Sears Optical near the centre of this very spread-out town (think Canberra with a river rather than a lake). They had the particular lenses I use and at a very good price, and the opening hours were 10am to 6pm at the weekend (which is considered very generous in these parts). Drove there, getting only a little lost on the way. Little Rock is about an hour's drive from where I actually live. Wandered around the deserted store for a wee while and was finally directed in a sweet, ever so polite Southern accent to the Optical desk around the back of the children's wear department, about twenty paces away.

It was deserted and just a little more empty-looking than I expected for 2pm on a Saturday. I looked around inquiringly and then went back to the sweet Southern belle I had asked directions of, to be told in matter-of-fact, very polite tones, "oh, they've gone for the day" with just the slightest hint of "you silly foreigner". Muttering invective, but only to myself, I departed.

My third attempt, immediately after the second, involved driving at some speed to a mall I had visited earlier and in which I had memories of seeing a rack or two of glasses. I triumphantly found the optician, admired the gleaming spectacles briefly and presented my prescription at the desk. It was inspected carefully and then handed back with the information, delivered in a sweet, very polite Southern accent, that here in Arkansas opticians weren't allowed to dispense contact lenses, only doctors could do that, and as anybody could see by the darkened door in the back, the doctor was not there and would not be back until Monday. Apparently my NZ prescription from a real live optometrist doesn't count for much. I pitifully asked for help and was directed, sweetly and ever so politely, to Wal-mart.

I was not holding out much hope at this point (I had tried Wal-mart before. You can buy anything there, except contact lenses). But I dutifully drove the ten or so miles to the specific Walmart to which I had been directed, on the edge of town, and fronted up at their gigantic Wal-Vision or whatever the heck it's called. I waited and waited while the sweet polite white-coated people dealt with their sweet polite customers, and while they chatted to each other, and passed the time of day, and eventually it was my turn. I somewhat briskly presented my prescription to a bona fide eye doctor, and it was duly and politely inspected and admired, every single part of it, and it was a good four or five hours later that she told me in a sweet, gentle, ever so polite Southern voice, that she didn't have those particular lenses in stock. But if I came back in two weeks she could order them in for me.

I accepted this information with what I felt extreme good grace, given I was standing in the biggest flaming optometrist's I have ever been in, only about fifty miles from Wal-Mart HQ, and I allowed through gritted teeth that since I was on my last pair, and that I'd been wearing them for three weeks already, and if I had to wear them for two more weeks my eyelids would fuse shut, I was happy to use any of a dozen other kinds as long as they let me see, but I was told in sweet, polite tones that the law here in Arkansas prevents me from acquiring any kind of contact lenses other than the ones specifically on my prescription. I had spent two or three hours trying to buy lenses by now, and was just a mite frustrated, so decided to give it a rest for the day.

My nearly-penultimate try was the day before yesterday, Monday, when in a light-bulb moment I remembered there was a Sears right here in Pine Bluff. I googled, and lo and behold it had an Optical part! Hours 10am to 6pm, so I have to take time off work, but that's fine! I'll be able to see! I called their number. No answer, but the voicemail message was ever so polite and re-stated their opening hours. They didn't call back. Never mind, they must be very busy. In high spirits I went in. In good cheer I asked directions. In a sweet polite voice I was told it was just past the lawnmowers. In joy I strode. In dismay I read the large, permanent, sign stating "Monday: closed". In bad humour I strode out, past the giver of directions who must have known it was closed on Monday, the brainless woman.

On Tuesday I returned extremely grumpily for what I now know to be my penultimate attempt, at 12:05, figuring that lunchtime would probably be a busy time for them but hey, I just need lenses, it's a quick transaction. I strode. I looked with mounting anger at the hand-lettered sign: "back at 1pm". I strode out. I may have shot some people on the way out.

On Wednesday at 10am I strode back. And he was there! I requested lenses. He gravely and at some length inspected my prescription. He gravely and at some length informed me in a sweet, very polite Southern tone that while he was wearing a white coat, he was not a doctor and could not sell me lenses. The doctor, he said, comes at 1:30. I was about ready to shout, but he must have sensed it (I don't believe anybody has shouted here since 1776) and allowed as the doctor did have another place of business and was there now. I exercised great restraint and did not execute him. I strode, I drove. The doctor, in a sweet, polite, somewhat incoherent Southern accent, made conversation at length about my accent, my nationality, the fact that he had once met a New Zealander in the 60s, asked in detail about the future of the mill, glanced briefly at my prescription and said "we don't have any in stock, we'll have to order them in, it'll be a couple of days. But here are some other ones you can wear until then". And handed over a dusty pair of odd-branded lenses, in blatant contravention of the laws of Arkansas which forbid me from wearing anything other than Acuvue Advance II .

But I strode away happy, because at some point in the next few days a small box will arrive in the mail, and I will be able to see again.

This, gentle reader, if you're still here, is why America is still stuck in Iraq.

Done! Three weeks to go til I come home

Hello dear internet! The go-live is over and done with and I can finally exhale. Here's what my life has been about for the past little while: lots of tasks on whiteboards.


That's not very interesting to anyone outside of the project so here are some interesting things in the sky. Part one: I think this is called a "sundog". It's like a little segment of a rainbow, without the rest of it. Weird. Taken from an SUV doing 75mph down the freeway, so please excuse the lack of focus.


And this is a sunset outside t'mill, on the first day of the four-day cutover. The foreground flag is the Arkansas state flag. Not sure what the background one is, I don't think I've seen it before....


Yeah, that was lame. Sorry.

And in the odd few moments I've been able to snatch, I've been listening to a lot of American podcasts. The radio stations here aren't up to much so I'm getting my fill of NPR and Common Sense (really slow ugly site, but great podcast content) over the internet, same as always. Recommended listening!

I'm coming home on 3 June. If anyone wants me to bring any gadgets such as iPhones, they'd better let me know pretty soon....

Ceiling Cat

Our office is now adorned with a Ceiling Cat,overseeing the food supply. I wonder who will be the first to notice.


Close-up of my somewhat clumsy papercraft skillz. It's been a long time since I got out the scissors and sellotape and made something, so it's a bit scruffy-looking.

Wildlife Weekend

I went to Memphis for the weekend (at a cost of 72kg of CO2 emissions). Without any real intention on my part it ended up being all about the wildlife. Spring is in full flower here (unlike snowy London, as my brother is experiencing), and all the animals and birds are out of hibernation or back from their winter holidays and ready to party.

The parade of wildlife started with American bison, in a farm park in Memphis. Interesting fact: bison like to wallow in ponds. Not many people know that. And boy, do these things have big heads:

Then a basking turtle in another pond in the same park. Rod and I had planned to go for a short walk around the pond but the path had other ideas, and we clocked up more than 16,000 steps according to my pedometer... the turtle hadn't moved when we got back to the pond after 90 minutes. Rod thought it was fake:

I know these ones weren't fake, because just after I took this photo (waaaaayy zoomed in) they took fright at my presence and splashed off the log into the water.


And this one dove for the bottom a microsecond after I got this shot. Turtles are scaredy-cats....


...unlike midges, which are suicidal little sods. Front grille of my car after the 170-mile trip back to Pine Bluff, at speeds in excess of 75 mph for much of the trip. I had to re-fill the windscreen washing liquid.


Just to remind you that it's not all bugs and bison over here, here's another shot of my workplace. Pretty, isn't it? It's a sunrise, by the way, just as I arrive at work.


And, not that I want to bring you down after all those cheery wildlife shots, but here's a pic of our project room. Yes, that's a bucket in the corner below a missing tile in the ceiling. We've had a little trouble with leaks lately and I don't mean the media.


That's all for now. Back to work for me.

Earth Hour 2008: turning my lights off

Since I last updated this blog I've been to NZ and back. Did I take lots of pictures of the wonderful Indian summer weather, my many gorgeous and intelligent friends (hi guys) and their lovely new babies, or my beloved and missed family? Nup. Too busy enjoying myself.

So what did I bring out my camera for? This unassuming little bottle.

I was thirsty when I got to LAX (no fault of Air NZ, they were quite happy to keep pouring any one of a hundred expensive liquids into me for the duration of the flight). So I bought a bottle of water, attracted by the pretty flower on it and the name, FIJI, which reminded me that there are beaches and sunshine in the world. Then I forgot to drink it.

Serendipity struck: on the next flight I read an article in the New Yorker about the owner of the company which bottles the water, and read the fine print on the back. It's not just named after Fiji, it's from there.

Fijian water, flown from Fiji to LAX, bought there and flown to Dallas and then to Little Rock and then driven to Pine Bluff. Water. It's free, it's heavy, and I just bought some and flew it hundreds of miles. No wonder I'm such a carbon-criminal. *Smacks self on wrist*. I'm keeping the full bottle as a reminder to myself.

I've done the maths and I'm now at 8,011 kg of CO2. That's how many trees? Even Google doesn't pretend to know! Searching on "a tree absorbs tons of carbon per year" gives answers like:

A healthy tree stores about 13 pounds of carbon annually

[www.coloradotrees.org/benefits.htm] ......

This is an average of 12.5 kg per tree per year

[www.carbon-info.org/carbonnews_072.htm] ......

a mature tree only absorbs 7.5 kg of CO2 per year, while a young and actively growing tree can absorb 13 kg+ of CO2

[www.carbon-info.org/pressrelease/pressrelease] .....

each tree will absorb 1 ton of CO2

[www.carbonify.com/carbon-calculator.htm] .........

A single mature tree can absorb up to 50 pounds of carbon dioxide per year

[www.greatermemphisgreenline.org/treevalue.htm] ..........

roughly one metric ton of carbon per acre per year

[greenmyplanet.blogspot.com/2007/12/how-much-is-tree-worth.html] .....

in the lower Mississippi River Valley, on a per planted tree basis, each tree absorbs an average of approximately 1.33 tons of carbon dioxide

[www.institutoterra.us/learn] .............

How is it measured? I need to see some peer reviewed scientific research. But I'm sleepy now, because it's late, which is because every detailed scientific page I read leads to ten random minutes browsing wikipedia/slashdot/xkcd/arts&lettersdaily/other people's blogs/etc....

So I'm going to turn out the lights and go to bed.

Oh, speaking of turning out the lights: turn them out at 8pm Saturday to participate in Earth Hour. If you missed it, turn them out NOW! After the mandatory ten minute random browse , of course.

Home on Good Friday!

Yes, that's right! We've rejigged the project plan a bit, and it now makes more sense for me to come home this week rather than the first week of April, so I leave here on Wednesday afternoon and arrive in lovely lovely Auckland early on Good Friday morning. Yay! I get to see all of my lovely lovely friends and my lovely lovely family and eat good food and sleep in my own bed!

See you all soon!

(PS: No offense, Pine Bluff).

Something to think about

Heard on the BBC: The average life contains less than a thousand months.

And I'm spending six of them in small town Arkansas.

Snow Pics

So the first car said to the second car, "I guess we're not going anywhere today".


Snow coats every twig.


My footsteps... the footpath had been trodden down into ice, so I walked on the grass (which was under 3 inches of snow)...


... and collected it in the turnups on my jeans.



It's nearly 9am and the sun is melting the snow so fast it's falling off the trees like rain.

A short video of a tree steaming. (3MB; I need to work out how to compress video).




It's -5 degrees out but it's crisp and dry and doesn't feel cold until you get wet. Now I'm going to watch one of my neighbours manoeuvre his 4WD out of the carpark....

Saturday, 8 March 2008

Testing video posting, with a song I love on YouTube.... These guys are called The Cat Empire, they're Australian, and they deserve more fame than they have. Let's see if this works.





Well. That was easy.

Even more snow! And this time it stuck around!

As I write there is snow falling softly outside. It's formed little hats on the lamp posts and duvets on the parked cars, and lined the top of every twig with white. One of my neighbours is frolicking with his dog in the three or four inches of fresh powder snow on the ground. It's so PRETTY!

Pretty damn hard to drive in. It took 40 minutes to get home from t'mill; it usually takes 10.

Pics as soon as my camera battery recharges.

Snow at last!

After that lovely summery hot weekend, it snowed today! See this news article for proof. We only got a few flurries here but I got to drive through it to work, which was very pretty. No pics, sorry.

Apparently it might do it again on Friday - yay for winter's last gasp. Punxsutawney Phil was right.

Spot sponsorship on CNN

Just watching CNN Morning. They brought up a flu map showing every state except Florida had widespread flu outbreaks (yes, including Hawaii and California). Then the sponsorship for that spot played their ad: Florida Orange Juice ("stay healthy, drink orange juice"). And now I trust the map, and by extension CNN, a little less.

Golf on the first warm weekend of spring


At Pine Bluff Country Club, with Deb and Gabb. We didn't quite play all 18 holes because it got dark, but it was a lovely lovely day. This is me sinking about a dozen balls in a row into the water hazard, which Gabb renamed Lake Carolyn. (yeah, there are two of me in the photo - Gabb did something nifty with Photoshop).


This is the second hole, with me and Debbie in the left foreground. What you can't see is the many squirrels bouncing around all over the greens. I'm sure they stole at least one of my a-bit-off-the-fairway balls...



Rented clubs: woods made of actual wood! I've never seen that before. They felt quite similar to my cheap half-set in NZ though. And of course I could blame all my duff shots on having old clubs ...

Hey Carolyn, have you forgotten about the environment?

Yeah, pretty much. It's amazing how easy it is to forget it, here. But at latest count I've produced 3652 kg of carbon dioxide. (that includes daily living, flying NZ to USA, flying Little Rock to Houston return, and all the driving I'm doing here).

Extrapolating out, that's over 21,000 kg of CO2 for the year. That's more than most people, according to this calculator here:

http://www.carbonneutral.com//shop/results.asp?cat1=Citizen

Haven't done anything to offset it yet. I did buy a bunch of CFLs for my rented apartment in Pine Bluff, but I won't be able to judge the impact of that until I get a power bill.

According to Wikipedia (which of course is always absolutely correct), a tree in the tropics absorbs about 22kg of CO2 per year, and a tree in the temperate zones about a third as much. So after some Excel wizardry, my impact so far this year could be offset if I planted 1162 trees in New Zealand. That's quite a few trees. I might have to buy some land.
