Forbes, here, and reports that China is building a  200 MW solar farm in the Gobi Desert (Clean Technica, here, IFL Science, here.

However, Chinese authorities plan for carbon emissions to peak in 2030 – that is to keep increasing until 2030.  Bellona, here, reported that Chinese authorities plan to increase renewables to 20% by 2030. This will include 200 GW of Wind, 100 GW of Solar. The plan is also to increase burning of Natural Gas to 10% of their electricity capacity, and to focus on coal with carbon capture. (Apparently the Chinese authorities don’t seem to realize how much carbon sequestration really costs. It is, as they say in New England, “wicked expensive.”)

The Celestial Shooting Gallery, Part Four: “You Have Nothing to Worry About (click) Worry About (click) Worry About (click)…”

Stability Model of an experimental distribution grid

A stability map of a simple power grid. Each point on this image represents an operating state of a simple power grid consisting of a few generators. Bluish regions constitute stable working states, red unstable and ‘salt-and-pepper’ represent chaotic behavior. One can tune a grid for stability by controlling the phasing of generators and transformers on the grid and such settings suffice for day-to-day operations. It is difficult to decide where, or by how much, abnormalities such as geomagnetic storms might push a system into red, unstable regions, or, worse, salt-and-pepper regions where the system oscillates between states. It is easy to find cases on the map where chaotic regions lie very close to stable regions, indicating that the destabilizing push need not be large at all. James Thorp, Cornell University, published in IEEE Spectrum

People paid to worry about the North American power grid regard geomagnetic storms as “high impact, low-frequency” events, spawning the inevitable acronym: HILF. Low frequency, in that a geomagnetic storm as intense as May 1921, at 5,000 nano-Teslas/minute, or the 1859 Carrington Event, best guess: 7,500 nano-Teslas/minute, might not happen in our lifetimes, the lifetimes of our children, or even our grand children. If signature traces in Arctic ice core samples are correct, these are ‘500 year events.’ When it comes to deciding where to put that preventative maintenance dollar, storm-proofing Oklahoma elementary schools against EF 5 tornadoes seems a far more practical spend than the hardening of electrical grids against a half-theoretical event that might not even happen in 500 years.

What pulls planners up short is the high impact part: the utter god-awfulness of a power grid that crashes and which then can’t boot itself up. There is a self-referential dependency: fixing a dysfunctional power grid requires it to be functional, as key aspects of the manufacturing of transformers need electricity.

Nor can one expect the cavalry to ride in anytime soon, as the vast geographic reach of geomagnetic storms means that one strong enough to take down the North American grid may very likely take down Eurasian grids as well – entire hemispheres could wind up in the toilet, and we only have two hemispheres. That and the statistical variableness to it all: the Carrington 1859 and May 1921 storms, nominally two ‘500 year events’ were, in fact, separated by only sixty-two years.

Where does the buck stop? Continue reading

Celestial Shooting Gallery, Part Three: When a CME Hits the Atmosphere

Failed GSU transformer at Salem River, NJ

A Generator Step Up (GSU) transformer failed at the Salem River Nuclear Plant during the March 1989 geomagnetic storm. The unit is depicted on the left; some of the burned 22kV primary windings are shown on the right. Though immersed in cooling oil, the windings became hot enough to melt copper, at about 2000 degrees F. John Kappenman, Metatech

Coronal Mass Ejections are mainly charged particles, protons and electrons. When a CME arrives at Earth, the charged protons and electrons come under the influence of the Earth’s own magnetic field, the magnetosphere. Charged particles spin around the lines of magnetic force that comprise the magnetosphere, which diverts most of CME harmlessly around the planet, keeping Earth’s surface tranquil.

If the ejection is large enough, however, it can distort the shape of the magnetosphere, occasionally causing magnetic flux lines to snap and reconnect. When this happens, charged particles leak in and follow the magnetosphere’s flux lines down to the Earth’s ionosphere. There, they strike oxygen and nitrogen molecules and strip them of electrons. These ionized gases glow, giving rise to the ethereal beauty of the auroras around the north and south poles. Unfortunately, these excess charged particles also produce immense electrojets.

Celestial Shooting Gallery, Part Two: The Physics of Geomagnetic Storms

goddard_cme_earth

On August 31, 2012 a long filament of solar material that had been hovering in the sun’s atmosphere, the corona, erupted out into space at 4:36 p.m. EDT. The coronal mass ejection, or CME, traveled at over 900 miles per second. The CME did not travel directly toward Earth, but did connect with Earth’s magnetic environment, or magnetosphere, causing aurora to appear on the night of Monday, September 3. The image above includes an image of Earth to show the size of the CME compared to the size of Earth. NASA Goddard Spaceflight Center

Thursday, May 2nd, 2013, a coronal mass ejection (CME) hurled nearly one billion tons of charged particles from the sun’s corona at an outward velocity of one million miles per hour – 270 miles per second.

In less than a half hour, 2,700 virtual Empire State Buildings, 340,000 tons apiece – give or take a few gorillas – erupted from an active region of the Sun’s surface called AR1748, a northern latitude sunspot. AR1748 had just become visible on the western limb of the Sun’s surface when it ejected this mass, so the vast bulk of it hurled outward, not toward us in Libra, but more or less toward Cancer, at right-angles to us. In practical terms, it shot wide of its mark. Still an impressive shot. The CME had been triggered by an M class solar flare, the second largest in a five step scheme (An, Bn, Cn, Mn, Xn; for n a relative magnitude). It had been the largest coronal mass ejection observed thus far in 2013.

And it was still early in the day for AR1748.

Celestial Shooting Gallery, Part One: The Day We Lost Quebec

Electrojets over N. America

John Kappenman reconstructed the electrojets which formed in the ionosphere late in the March 13, 1989 geomagnetic storm which compromised the Hydro-Quebec power grid in Canada. Concurrently, the eastward jet induced ground currents that severely strained the electrical distribution grid of northern continental United States, resulting in a transformer failure at the Salem Nuclear Power Plant, in New Jersey. Courtesy of Metatech

Nearly a quarter century ago, on March 13, 1989,  a geomagnetic storm led to the collapse of the Hydro-Quebec electrical grid system, which furnishes power to much of the province of Quebec, Canada. So pervasive were abnormal currents, that protective circuit breakers tripped throughout the system, bringing the entire grid to a halt in about one and a half minutes. The grid’s self-protective systems were geared toward local abnormalities happening in particular places. In contrast, ground induced currents created abnormalities everywhere. The good news was that most of the hardware protected itself. The bad news was that six million customers were without power for as long as nine hours, and where transformer damage did occur, outages continued for another week.

Further south, the United States experienced a close shave. A second surge in the March 13 storm generated similar ground induced currents in the northern United States, with large current spikes observed from the Pacific Northwest to the mid-Atlantic states, one spike destroying a large GSU transformer at the Salem Nuclear Power Plant in New Jersey. According to John Kappenman, of the Metatech Corporation “It was probably at this time that we came uncomfortably close to triggering a blackout that could have literally extended clear across the country.”

Earth Day, 2013. Oil Spills, Explosions, Fracking Business As Usual & The Stock Market Response

PLPort_Results.2013.04

Wall St. NYC, April 26, 2013. Monday, April 22, 2013 was Earth Day.  At the close of trading Thursday, April 25, 2013,  as compared to my reference date of Dec. 21, 2012, the Dow Jones Industrials was up 12.3% , the S&P 500 closed up 10.84%, the “Popular Logistics Fossil Fuel Reference Portfolio was up 1.8% and the Popular Logistics Sustainable Energy portfolio was up 34.85%. (This is in line with the trend noted in my previous post, March 23, 2013., in the series that began Dec. 21, 2012.) And Shell Oil has temporarily suspended exploration and drilling operations in the Arctic. (Click here for Forbes). The stock portfolio data are summarized below, in Table 1. That’s the good news (unless you’re long on fossil fuels).

Here’s the bad news. “Fracking” is widespread and unregulated (click here).  An oil spill dumped 500,000 gallons from Exxon pipeline onto Mayflower, Arkansas and into Lake Conway (click here).  A fatal fire & explosion in West, Texas left 35 dead, probably including 16 firefighters and emergency responders (click here).  A fire and multiple explosions on gasoline transport barges docked in Mobile, Alabama injured 3 (click here).  Continue reading

Apple, Google, IBM – the way forward

Apple HQ, in Cupertino

Apple HQ, Cupertino, California

Back in 1965, IBM CEO Thomas J. Watson, Jr, wrote, in IBM’s Basic Beliefs & Principles,

“We accept our responsibilities as a corporate citizen in community, national, and world affairs; we serve our interests best when we serve the public interest…. We want to be at the forefront of those companies which are working to make the world a better place.”

Today, IBM says “Sustainability is no longer an option. Sustainability is an imperative.” IBM is focused on making data centers and supply chains more efficient, and providing their customers with tools to become less unsustainable (IBM green blog). The European Commission awarded IBM for energy efficiency at 27 data centers (IBM Press Release).

However, it looks to me that Google and Apple are one or two steps ahead of IBM. Google has invested $915 Million in solar arrays, which should be 1.0 to 1.5 MW. Apple is putting a 5MW solar array on the roof of it’s headquarters in Cupertino, pictured above, and described here on Treehugger and here on 9to5mac. Apple is also using solar and biofuel to power it’s new data center in South Carolina (article in Renewable Energy World). Essentially:

  • A 100-acre, 20 megawatt (MW) solar array, supplying 42 million kWh of energy each year.
  • A 5 MW biogas system to come online later this year, providing another 40 million kWh of 24×7 baseload renewable energy annually. Apple claims this will be the largest non-utility-owned fuel cell installation in the US.
  • Combined, that’s 82 million kWh/year of onsite renewable energy generation at the facility.

For more details, see the 2012 Apple Facilities Report.

Apple’s building may be a derivative design of the Widex headquarters, in Allerød, Denmark, described on Widex home page,  here. The Widex building is a ring that surrounds a large atrium courtyard to be planted with grass, flowers and trees and is according to Widex,”designed to be both pleasant to look at and be in…. and environmentally friendly

Heat for the building will be supplied by a geothermal system, where groundwater is used like a heat reservoir; excess heat in summer can be stored and used when needed during winter. Our ambition is to reduce energy consumption by 75 percent compared to traditional technology.

Apple, Google, and IBM report high profits. Their stock prices are also high, perhaps demonstrating the correlation between doing well and doing good.

The World Will Not End & Other Predictions for 2012

space-apple-logo

 

Here are my top 10 predictions for 2012. These are less readings of the tea leaves or the entrails of goats and chickens and more simple extrapolations of patterns in progress. Altho that may be the way effective oracles. They just masked their observations with hocus pocus, mumbo-jumbo, and guts.

This list runs a gamut from business and technology to energy, instability in the Middle East, micro-economics in the United States, politics, and not-yet-pop culture.

  1.  Apple and IBM will continue to thrive. Microsoft will grow, slightly. Dell and HP will thrash. A share of Apple, which sold for $11 in December, 2001, and $380 in Dec. 2011, will sell for $480 in Dec. 2012.
  2. The Price of oil will be at $150 to $170 per barrel in Dec., 2012. The price of gasoline will hit $6.00 per gallon in NYC and California.
  3. There will be another two or three tragic accidents in China. 20,000 people will die.
  4. There will be a disaster at a nuclear power plant in India, Pakistan, Russia, China, or North Korea.
  5. Wal-Mart will stop growing. Credit Unions, insurance co-ops and Food co-ops, however, will grow 10% to 25%.
  6. The amount of wind and solar energy deployed in the United States will continue to dramatically increase.
  7. The government of Bashar Al Assad will fall.
  8. Foreclosures will continue in the United States.
  9. Arizona Sheriff Joe Arpaio will resign. Calls for Clarence Thomas to recuse himself from matters involving his wife’s clients will become louder, but Justice Thomas will ignore them. A prominent politician who says “Marriage is between a man and a woman,” or her husband, will be “outed” as gay. President Obama will be re-elected.
  10. The authors of Vapor Trails will not win a Nobel Prize for literature. They will not win a “MacArthur Genius Award.” Nor will I despite my work on this blog or “Sunbathing in Siberia” and the XBColdFingers project.

Here are the details … Continue reading

Matt Wald on Renewable Energy Surpluses

Grand Coulee Dam   Follow LJF97 on Twitter Tweet To paraphrase Bob Dylan,”The answer my friend, is storage of the wind.

We have long been saying that the question is not:

“Can clean, renewable and sustainable energy power the grid?”

It is:

“How can we harness clean, renewable and sustainable energy systems to power the grid?”

As Matt Wald observed in Taming Unruly Wind Power, shattering the conventional wisdom, the critique of renewable-resource energy is that it’s “not enough;” turns out to be wrong. In some places on some days, it’s not only enough, it more than we need. When the winds blow and the rains fall, a power grid built on wind and big hydro turbines, i.e. the northwest grid built on the Grand Coulee Dam, pictured at left, and the wind farms in the Columbia Gorge, below left, can get overloaded. So while you can never, according to the conventional wisdom, be too thin or too rich, you can have too much energy.

The corresponding criticism, that wind and solar don’t work in a storm, also applies to nuclear power. Wind farm in Columbia GorgeAs noted here, on Popular Logistics by Lawrence J. Furman, eight nuclear plants from North Carolina to Connecticut were shut down due to Hurricane Irene or the earthquake that preceded it.  Wind and solar, however, unlike nuclear, come on automatically after the storm.

Excerpted from Matthew L.  Wald:   Taming Unruly Wind Power, published in the New York Times, on November 5th, 2011

For decades, electric companies have swung into emergency mode when demand soars on blistering hot days, appealing to households to use less power. But with the rise of wind energy, utilities in the Pacific Northwest are sometimes dealing with the opposite: moments when there is too much electricity for the grid to soak up.

In June 2010, for example, a violent storm in the Northwest caused a simultaneous surge in wind power and in traditional hydropower, creating an oversupply that threatened to overwhelm the grid and cause a blackout. As a result, the Bonneville Power Administration, the wholesale supplier to a broad swath of the region, turned this year to a strategy common to regions with hot summers: adjusting volunteers’ home appliances by remote control to balance supply and demand. When excess supply threatens Bonneville’s grid, an operator in a control room hundreds of miles away will now dial up a volunteer’s water heater, raising the thermostat by 60 more degrees. Ceramic bricks in a nearby electric space heater can be warmed to hundreds of degrees. The devices then function as thermal batteries, capable of giving back the energy when it is needed. Microchips run both systems, ensuring that tap-water and room temperatures in the home hardly vary.

“It’s a little bit of that Big Brother control, almost,” said Theresa Rothweiler, a teacher’s aide in the Port Angeles, Wash., school system who nonetheless signed up for the program with her husband, Bruce, a teacher. She said she had been intrigued by an ad that Bonneville placed in the local paper that asked consumers to help enable the grid to absorb more renewable energy, especially wind. “We’re always looking at ways to save energy, or be more efficient or green, however you want to put it,” said Ms. Rothweiler, who worries about leaving the planet a livable place for her 21-year-old daughter, Gretchen. Bonneville paid for the special technology, which runs around $1,000 per home. The initial goal of Bonneville’s pilot program is to gain experience in charging and “discharging” the water heaters and space heaters to see how much response operators can count on as the use of these thermal batteries expands.

Mark K. Lauby, director of reliability assessment at the North American Electric Reliability Corporation, which enforces standards on the grid, said that such storage innovations would be “the holy grail” as the nation shifts to greater reliance on renewable energy. While the threat of excess supply is most severe in the Pacific Northwest, other regions may land in the same situation in coming years because a surplus would threaten to destabilize the electric system as much as a shortage. California, for example, is committed to getting a third of its electricity from renewable sources by 2020. That would be harder if it had to turn off the wind machines on their best generating days to prevent the grid from being overwhelmed.

For decades, the Bonneville Power Administration rarely had a problem with excess supply. Its backbone is hydroelectric dams on the Columbia River, and while the operators must often run all of the falling water through its power-producing turbines for environmental reasons, the grid could adjust the supply by turning off fossil fuel plants. That balance began to shift over the last few years as entrepreneurs built hundreds of wind machines nearby in the Columbia River Gorge, an area that utility executives now call a “wind ghetto.” While the wind turbines produce electricity far below their capacity most hours of the year, they get busy when a storm rolls through, which is when river flows are highest, too.

Beyond Fuel – for the 21st Century – Cocoa Beach, Sept. 17

Space Coast Green Living Festival

Follow LJF97 on Twitter Tweet I will be presenting Beyond Fuel: From Consuming Natural Resources to Harnessing Natural Processes at the Space Coast Green Living Festival, Cocoa Beach, Florida, Sept 17, 2011.  The festival  is sponsored by the Cocoa Beach Surfrider Foundation and the Sierra Club Turtle Coast Group. It will be at the Cocoa Beach Courtyard by Marriott. Haley Sales, (Website / Facebook / Youtube),a local singer / songwriter, will perform.

Our current energy paradigm today is to fuel based. We burn oceans of oil and methane mountains of coal. And there are consequences.  We suffer oil spills, polluted water, mercury, coal mine disasters, nuclear power plant melt-downs, we fight wars …

According to the DoE, in 2010 we burned 1,085,281 thousand short tons of coal and 15,022 thousand short tons of coke (here).

Wind and solar don’t burn fuel. The winds blow, the sun shines, you put a widget in the path of those moving particles in the air or those photons of light and you get electricity – without greenhouse gases, radioactive wastes, toxic wastes, and it costs less. So the question is not ‘Can we meet our energy needs with clean, sustainable renewable energy technologies?” The real question are How? How Much? And How quickly?

100% Clean Energy
100 Gigawatts Wind $300 Billion
100 GW Marine Hydro $300 B
50 GW Solar $200 B
50 GW Geothermal $200 B
200 GW Equiv Efficiency $200 B
A Smart Grid $100 B
500 GW or GW Equiv. $1.3 Trillion

And we could do it within 25 Years if we wanted to.

Amory Lovins, of the Rocky Mountain Institute, coined the term “Negawatt” to mean energy you don’t need to buy, as in “The cheapest unit of energy is the one you don’t have to buy.” The next cheapest, the “nega-fuel-watt” is the unit of energy that doesn’t require fuel.

Six solar cells powered a 5-milliwatt transmitter (a second transmitter was powered by a battery). The solar powered transmitter lasted for six years.
This post is part of an occasional series through which we hope to investigate the progress and promise of solar power.  And its limitations.  So we’re looking for  data points, landmarks, so we can plot the vector of solar power over time. One of our first posts on Solar, “Staten Island Ferry – Sailing to the Future,” posted here, March 8, 2007, noted the 40 KW array on the Staten Island Ferry Terminal, at the base of Whitehall Street in New York City.
