Watch Carbon Dioxide Emissions in Real Time

Carbon Dioxide and Nuclear

The first meeting of the nuclear energy study group at Dartmouth was true to its name: Nuclear Power for Climate and for People.  Bob Hargraves gave an excellent presentation on carbon dioxide and the role nuclear energy can play in carbon dioxide abatement.

I sent the class members links to sites where you can watch the carbon content of the electricity sector, pretty much world-wide.  Here's the note I sent.


https://www.epa.gov/ghgemissions/sources-greenhouse-gas-emissions
Carbon Dioxide Emissions

Our first session was mostly about climate change.  In general, the electric sector is only part of the problem: industry, heating and transportation are important sources of carbon dioxide emissions.  However, almost all decarbonization plans for those emissions involve using electricity in other sectors: electric cars, heat pumps.  So the carbon dioxide content of the electric sector is essential, right now and in the hopefully-decarbonized future.

Real Time Electricity

Screen grab of electricitymap selection at 11 a.m. January 20
Now, back to the  electricity sector.  Interactive sites are fun, because you can watch them in real time.  Or maybe I just have an odd idea of fun....

Here's a real-time, interactive map of world-wide CO2 emissions. Many (but not all) countries are on it. https://www.electricitymap.org/?wind=false&solar=false&page=map

Little stuff: To move between areas in the map, click and hold. While holding, you can drag the map around with your mouse. You can also zoom in and out with your mouse. Wind and solar are listed as "false" above, because I have not checked the "wind solar potential" boxes. I am suspicious of the word "potential." I want real time data, not projections.

France and Germany

For fun, let's click on France, which is green on the map.
France is at 39 grams CO2 per kWh right now (it generally hangs around at that level)
96% low carbon electricity
25% renewable (hydro, I believe)

Okay, next, let's click on Germany.
Germany is at 470 grams CO2 per kWh (it is at that level a lot, but sometimes goes down to the 300s or even high 200s.  Watch it for yourself.)
It has 42% low-carbon electricity
22% renewable, probably hydro and wind

The difference between the low-carbon and renewable numbers is nuclear--low-emissions but not renewable.

Data is from around 9 a.m. this morning, January 20

New York, Ontario, Alberta

From EmissionTrak at 11 a.m. January 20
This website gives a week's worth of emissions for New York, Ontario, and Alberta. The source of the emissions is color-coded. http://emissiontrak.com/cei/nyOnAb.html

Ontario is mostly nuclear and hydro, New York is mixed, Alberta is coal and natural gas.  I think their "other fossil" is coal. Coal is--- "He who must not be named."

Fun with Maps!

Enjoy these maps. I think "playing around" is the best way to find out stuff. Have fun. We will see you Thursday!

Nuclear Energy Study Group at Dartmouth OSHER

Black Swallowtail Butterfly
Wikipedia
Dr. Robert Hargraves of Thorcon Power (the Do-able Molten Salt Reactor) and I  will begin leading a four-session study group this afternoon. The study group is a course at Dartmouth OSHER, and the title of the course is Nuclear Power: For Climate and for People.

The course is oversubscribed (has a waiting list).  I always have some butterflies in my stomach before starting something new.  Anything new, despite how familiar some parts of it might be.  Yes, I have taught other courses and been on many stages. Yes, that helps.

I remember an Aikido sensei who told my class: "If you have butterflies in your stomach, make them fly in formation."

I am starting a new course this afternoon, with Bob.  All right.  Get in formation, butterflies!

Nuclear Power:
For Climate and for People

MIT Prof Kerry Emanuel, in his 2017 OSHER@Dartmouth summer lecture, raised awareness of the potential for nuclear power to reduce CO2 emissions that force global warming. Building more nuclear power plants is opposed by many on the grounds of health, safety, and expense. Fission power plants can provide inexpensive, ample power, especially for developing nations desperate to advance prosperity of growing populations. In four sessions we’ll cover the arguments against and for nuclear energy.

We’ll  first have a tutorial on energy, power, sources, uses, value to civilization and prosperity, energy poverty, and civil unrest where there is little. Second, we’ll review Emanuel’s lecture and book on global warming, CO2 in the air and ocean, the solar/ wind bandwagon, and the politics of IPCC, Kyoto, and Paris.  Third, we’ll cover how nuclear power works, why it’s opposed, and the future potential of energy cheaper than coal. Finally, we’ll cover activities of social organizations fighting for/against nuclear power.

There are no required texts for this course.

Robert Hargraves has taught OSHER@ Dartmouth courses on energy, politicized science, and internet money.
Meredith Angwin led The Grid and other courses for OSHER@Dartmouth.

4 sessions, 2:30 PM – 4:30 PM January 18 through February 8, 2018 DOC House - Hanover, NH

Vermont, "Hot Air," and Puerto Rico

Grid prices in the Northeast.  Running about 37c per kWh at 1 p.m.

Vermont

Vermont remains in the deep freeze. It was minus 5 here when I wrote this at 8 p.m. Saturday, and it was about zero at 1 p.m. Saturday when I took these screen shots.

The weather is actually colder now, Sunday morning.  It is minus 15 at 9 a.m. Fuel oil is supplying 37% of the grid now, and the price is around $300/MWh.  I'm going to use the screen shots I took yesterday, because things have not changed very much.  As usual, all charts are from the ISO-NE  ISOExpress web page.

On Saturday, fuel oil supplied over 30% of the grid electricity, and the price of power was bouncing around like crazy between $200 and $400 per MWh (five minute LMP graph at left).

Fuel mix (34% oil) at lower right,
5 minute LMP graph at left totally schizoid:
20 cents to 40 cents per kWh and back, rapidly

Meanwhile, with significant wind chill out there, wind was about half of renewables, and renewables are 11% of the grid, so wind was contributing about 5% of the power. (Same today, Sunday, but wind is about 40% instead of 50% of renewables.)

Wind is about half of the renewables now


Meanwhile, the fuel supply for New England has been getting a bit dicey. (It seems to be hanging in there, for which I am grateful.) According to an article in Reuters, Frigid weather sends heating prices soaring as energy usage spikes, spot gas prices in New England soared to a record-breaking $82.75/mmBTU before falling back to a more normal $3.80/mmBTU. More tankers are heading to the U.S. These tankers are not on a mission of mercy. Right now, the East Coast is the most high-priced market in the world for oil. The tankers can get their best prices, right here.

Coast Guard icebreakers have been used (probably still being used)  to keep open the ports of Boston, New York and Philadelphia.  A Coast Guard icebreaker was even needed on the Hudson River. Overall, the grid is working okay and I am not very worried.

But I must say:
I appreciate the Coast Guard!

Hot Air and Puerto Rico

Meanwhile, some of my earlier posts got some play in bigger media.  Jazz Shaw is a major contributor to the widely read blog Hot Air. On Thursday, Shaw wrote New England Wanted to Use All Renewable Energy...Then It Got Cold. This is a very well-referenced and well-written post.  Shaw quotes my blog extensively, and he also puts the issues in New England together with Rick Perry's aim of rewarding reliable power plants.

I should also mention that Hot Air is a very widely-read blog. As soon as the Hot Air post referencing my blog appeared, email after email arrived: "Hey Meredith, you were on Hot Air!  Great going!" It was fun.

Most of these emails came from my friends, but one note was from someone new to me.  A man who writes the Dark Island Puerto Rico blog wrote to say that Vermont and Puerto Rico seemed to be having some similarities.  He also wrote a blog post about this, also: Weather and Wind Problems.

I have been enjoying reading his blog. Puerto Rico has pretty much disappeared from the main stream news, but there are still huge areas without power. I find it very interesting to hear from a person who is really there, thoughtful and critical of about the recovery effort.  He has posts on the fate of wind farms, the useful possibility of battery back up for solar (but you still need a source of reliable power), how small modular reactors could be used, how cogeneration could be a robust future for Puerto Rico.  I recommend his blog http://darkislandpr.blogspot.com

They say there it is "an ill wind that blows nobody any good," which means that even bad situations can have some good in them.  The situation on the grid isn't great, to put it mildly.  However, my recent blog posts have introduced me to two new blogs: Hot Air and DarkIslandPR.  That is some good, and I appreciate it.

(Note to my readers: the Hot Air blog is mostly political, and DarkIslandPR is mostly about energy.  I don't want people to get the impression that I think the two blogs are very similar: they aren't. )

A Hole in the Community: When a Nuclear Plant Shuts Down


A hole in the community


What happens when a nuclear plant shuts down


Vermont Yankee

At its peak, the Vermont Yankee plant generated more than 70 percent of the electricity made in Vermont. It was the largest, most reliable source of clean energy in the state and one of the largest plants in the New England grid.

But like many other nuclear plants around the U.S., Vermont Yankee was no longer economically competitive and was losing money for its owners. Its closure would cause harm across many states – and for many years.

The environmental and economic effects of closing Vermont Yankee were severe, and they were completely predictable: air pollution increased, as carbon-free nuclear energy was replaced by natural gas; energy costs increased throughout New England, with utilities warning that customer bills could rise 50 percent or more during the winter; and the region’s economy slowed as 1,000 jobs and $500 million in annual spending dried up.

Most painful, though, was the human toll on the Vernon VT, community as nuclear workers were forced to leave behind loved ones and neighbors in search of work.

In the two and a half years since Vermont Yankee closed, many good people had moved on. Someday, the community might recover. But it will never be the same.

Economic Lessons

When he made his political case that Vermont Yankee should be “retired,” then-Gov. Peter Shumlin promised a “billion-dollar bonanza” for the state. Shumlin argued that, in the short-term, decommissioning a nuclear plant would provide employment, income and spending on par with a functioning power station. While Vermont Yankee was operating, it employed more than 600 people with salaries averaging more than $100,000 a year. Those dollars cycled through the local economy, creating hundreds more indirect jobs.

But closing the plant was not a jobs bonanza – it was a jobs cliff. Hundreds of people lost their jobs, and nowhere near that many jobs were created or likely to be created. To contradict Shumlin’s assertions, I looked at the history of other nuclear plants that closed. What I saw wasn’t pretty. One of the lessons learned about decommissioning was that a closing plant must downsize its staff quickly and aggressively, in order to decommission within the budget of the decommissioning fund.

Lessons learned were everywhere, but they weren’t happy lessons. Wherever a nuclear plant closes, the pattern repeats itself: employment and average incomes fall, which means that tax revenues that fund schools, government services, roads and communities fall, too. To make up the losses, tax rates must rise. In general, the first tax rate to rise is the local property tax.

At the same time, the departure of nuclear workers increases the number of houses on the market, and lowers property values. Local businesses also suffer as temporary workers hired for periodic refueling outages no longer come to town: the outage contractors no longer rent rooms, eat at restaurants, buy groceries or fill their cars with gas. They no longer give the area economy a cheerful boost of workers making good money, with money to spend.

Emissions of carbon and other pollutants rise as clean nuclear energy is replaced by plants that burn fossil fuels. And when a nuclear plant’s around-the-clock supply of electricity is turned off, the law of supply and demand dictates that energy prices must inevitably rise. Even though natural gas prices are low now, when a nuclear plant closes, it creates more competition for the natural gas and the price of gas rises. As natural gas prices rise, so do electricity prices.

About the people

NJ Needs Nuclear: Patty from PSEG on Vimeo.

Nuclear workers are highly skilled, highly trained and highly sought-after. There are jobs to be found at other nuclear plants – for someone who is willing to uproot and leave their friends, their kids’ schools, their churches, their doctors, their favorite restaurants, their church choirs or their poker buddies.

I believe these quotes, left by anonymous commenters on my blog, Yes Vermont Yankee, help illustrate the human side of the story:
Yes, I relocated. No, it was not easy. Selling a house, buying another one, moving, finding a new house with the right schools. Moving away from grown kids. Moving away from grandkids. My wife had to leave a job that she loved …”
“There is no way I will come close to breaking even on selling my house, not with the housing market the way it is … We have elderly parents and we don't know how we are going to manage ...”
In some cases, families were split as one spouse moved to take a new job at a faraway nuclear plant, while the other stayed behind to allow children to stay in school. A plant closure could break up a family for months or years.

Change will never be easy, and it will be harder for some than for others. But plant employees will move on, and they will live well.

For younger people, living well probably means getting out of town, taking their lumps on the declining local housing market and starting anew. Older people may see the loss of a job and community as a betrayal of their lifelong work and plans, and may be less able to start over or go somewhere new.

Today, Vermont Yankee is closed, and the region is forever the worse for it: More carbon in the air, fewer jobs, higher taxes and rising electric bills for those who stay. At one low point, during town meeting, the town of Vernon decided to disband its police force and sell off the cruisers. They could no longer afford their small police force. Hard decisions had to be made.

The Bottom Line

For a plant closure, it is comparatively easy to assess the bottom line in monetary costs.

Economic input to the area down severely, taxes no longer collected, energy prices going up. The human cost – people losing their jobs, becoming discouraged and displaced as they are forced to move to new areas – cannot be calculated.

I believe the nuclear industry will survive. Nuclear workers are smart and resilient. I think the future will work out well for all of them.

I’m less certain about the communities left behind.

More Cold and More Oil on the New England Grid

Oil Use Increases

Once again, I will tell this blog in a series of pictures.

In my blog of December 27, I showed a snapshot of the New England grid in the early evening.  The temperature at my location was 7 degrees, the local marginal prices (LMP) on the grid were running around $200 MWh (20 cents per kWh), oil was 22% of the fuel mix, renewables were 11% of the fuel mix (I remarked that this was on the high side for renewables) and the high renewable percentage was due to the wind energy.  Wind was 50% of the renewables.  The blog post was Successful encouragement of oil on the New England Grid.  The source of all the information (except the local weather) was the ISO-NE web page, ISOExpress.

That post was on December 27.  Yesterday, December 28, I noted that the percentage of oil had gone up above 30%, and the portion of renewables had gone down.  But I didn't write another blog post. My snapshot is below. (Double click on any graphic to enlarge it.)

December 28 fuel mix


Getting Colder, and Oil Use Stays High

Today, around 1 pm, the temperature was 1 degree, as show below. The weather had gotten colder.

1 p.m. December 29 temperature
The price of power on the grid had also gotten higher, around $300/ MWh (30 cents per kWh)

1 pm December 29 prices on the grid

Though I must admit that as I write this at 3 p.m, the price has fallen again to around $200/ MWh.  Also, note the color codes on the map.  The colors show the prices graphically.  Closer to red is higher priced.

Oil use has stayed high, from December 28 evening (above) to one pm December 29, (when I took a bunch of screen shots) to right now at 3 pm.  Oil has been between 30 and 32% of the grid.

December 29, oil is around 30% of grid power

Not as much wind on the grid

What about the renewables?  On December 27, a windy day, renewables were at 11% of the grid, and wind was 50% of renewables.  (See my December 27 post for the graphics on this.)

Today, at one pm, not so much wind.  It was actually snowing rather gently.  At that time, renewables were only 7% of the grid power, and wind was only 13% of renewables.

Renewable mix on the grid. Wind at 13%.
 What next?

I think oil use will remain high until the cold weather is over, about a week from now.   The wind may spring up again in the evenings, or it may not.  Whichever it chooses.  Nobody controls the wind.  So renewables may continue at 7% or go up to 11% again.

On the other hand, we haven't really hit peak demand yet.  Here's a screen shot that I just took. This is the ISO-NE estimate of system loads today, and the actual loads up until 3 p.m.
System loads, as forecast
As you can tell in this chart, around 18 hours (6pm) looks like peak demand.  Check in and see if the percentage of oil goes up even further.  I'm going to check.  I'm curious.

Here's the link for these real time updates from ISO-NE, ISO Express. https://www.iso-ne.com/isoexpress/

In conclusion

Isn't it nice that you can store oil on site?  Maybe someone will notice what Rickover noticed: you can store nuclear fuel even more easily than you can store oil!  I wouldn't hold my breath for people to notice this.  (/snark)

Meanwhile, I will check back at about the grid at 6 p.m. but I won't be posting. I leave the evening results as "an exercise to the reader."

Successful encouragement of oil on the New England Grid.

Cold in New England, and Going to Stay Cold

I decided to tell this blog as a series of pictures.  

I will start with a screen shot that I took of the weather report, at about 5:30 this evening. (Note that "Hartford" refers to the town of Hartford Vermont, where I live.)  It was 7 degrees F at that time, with a drop to minus 16 expected tonight.  The next few days are expected to have single digit high temperatures and minus temperatures of two digits (minus 10, etc)
Weather at 5:30 pm and forecast

So, how is the grid doing? Fairly well, actually.  At 5:30, I took this picture, showing that the LMP (local marginal prices) were running at about 20 cents a kWh. ($200 a MWh translates to 20 cents per kWh.) The graphics below are screen shots from ISO-NE. I took my snaps at 5:30 at this ISO page, which is updated every 5 minutes. https://www.iso-ne.com/isoexpress/

Grid prices and electricity use at 5:30 p.m. and throughout the day

As you can see by the retrospective graphs to the left of the map, prices have been up and down between $100 and $250  (10 cents and 25 cents per kWh) most of the day.

Oil on the Grid

During cold snaps, gas pipelines must supply homes first, and gas-fired power plants get short-changed.  ISO-NE has a Winter Reliability Program which mainly compensates gas-fired power plants for keeping fuel on site: oil or LNG or CNG. (Liquefied or compressed natural gas.) The grid was running about 22% oil at 5:30 this evening.

The current Winter Reliability program is described in an update presentation, given December 7,  2017  by Anne George of ISO-NE. On page 5, Ms. George describes the current winter reliability program, which pays oil and gas fired generators to have fuel on site.  (Page numbers are at the lower right of each viewgraph.) On page 18, she describes how the forward capacity auctions are attracting new generation, even as older plants retire.  Specifically, ISO-NE is attracting new dual-fired natural gas resources: gas turbines that can also burn oil, and therefore can store oil on-site for cold weather.

ISO-NE's attempt to provide winter electricity by encouraging oil use in cold weather is working.  The next picture shows (among other things) the fuel mix at 5:30 on the New England Grid. 

Fuel use at 5:30 p.m. and throughout the day
You can see that 25% of the electricity was supplied by nuclear, 24% by natural gas, 22% by oil, and 11% by renewables.  Usually, the grid runs closer to 50% natural gas and just a few percent oil. If you go to viewgraph 19 of the ISO-NE presentation,  you can see that natural gas is expected to be 55% of normal generation, and oil is the merest sliver on the graph.

The Renewables

In the chart above, renewables are making 11% of the power on the grid.  This is on the high side. (Viewgraph 19 of the ISO presentation shows renewables making 5%, for example.)  The high contribution of renewables is due to the wind.

In my experience of New England, really cold weather is often deathly still.  Not this time.  The wind is blowing, the windchill factor is serious, and the wind turbines are making considerable amounts of energy.  Wind turbines are making 50%  of the renewable power on the grid, as you can see in the chart below.  Basically, the other 50% of the renewable power is being made by burning wood and refuse. That power is pretty steady: the wind contribution goes up and down.

Since wind is making half the renewable power on the grid, and renewables are making 11% of the power on the grid, therefore,  the wind turbines are making 5.5% of the power on the grid. 

 The chart below shows the percentage of renewables on the grid at 5:30 p.m. 
Renewables on the grid at 5:30 p.m. 50% of the renewable power is from wind

The End of the Grid Tour

I am pleased that it is both cold and windy. (Actually, I am not that pleased about it. I have to live here, after all.)  I also know ISO must be fuel-neutral, so dual-fuel gas-fired generators are considered good. However, I can't help but think that using more oil in the winter is a step back for New England, not  a step forward.  

If you want, you can go to the ISO site, and watch the grid.  Or if you don't live in New England, look up your own grid, and do a compare-and-contrast. I would love it if you would comment on this article.

Audiobook Now Available for "Campaigning for Clean Air"


Audiobook of Campaigning for Clean Air is now available!

I am so pleased to announce that the audiobook version of Campaigning for Clean Air is now available at Amazon. You can buy it or you can rent it (so to speak) through Audible.  You can give it as a gift through Audible. It should be available at other vendors also, but I haven't checked them out yet.

Audiobook of Campaigning for Clean Air

Read by Pamela Almand

I was so happy that Pamela Almand agreed to read this book. She is a former pilot for Northwest Airlines: she flew 747s, often to Japan.  People told her that her voice was reassuring to the passengers.  Her voice is smooth, low-pitched and easy to understand.

Almand is in great demand as a narrator.  She has been a finalist for the Audie Awards, a finalist for the Voice Arts awards, and a winner in Voice Arts. You can see more of her work at Audiobooks by the Captain, and  TheCaptainsVoice.com 

I listened to quite a few examples before I decided that I wanted Almand to read my book.  She has the right voice quality and a strong technical background. But I wondered if she would narrate my book. My book can be seen as controversial: not everyone wants to narrate something about nuclear power. Almand has many projects from which to choose. To my relief, Almand liked Campaigning for Clean Air, and she narrated it!

You will really enjoy Almand's narration of Campaigning for Clean Air.  Like all audiobooks (and podcasts, etc.) you can "read it" in periods of time that might otherwise be wasted.  This is because you will be listening to it, not reading it.

I am happy that it is available, and I hope you enjoy it!
